dissenting.*
The Court has avoided the difficult problems raised by § 301 of the Taft-Hartley Act, 61 Stat. 156, 29 U. S. C. *461§ 185,1 by attributing to the section an occult content. This plainly procedural section is transmuted into a mandate to the federal courts to fashion a whole body of substantive federal law appropriate for the complicated and touchy problems raised by collective bargaining. I have set forth in my opinion in Employees v. Westinghouse Corp. the detailed reasons why I believe that § 301 cannot be so construed, even if constitutional questions *462cannot be avoided. 348 U. S. 437, 441-449, 452-459. But the Court has a “clear” and contrary conclusion emerge from the “somewhat,” to say the least, “cloudy and confusing legislative history.” This is more than can be fairly asked even from the alchemy of construction. Since the Court relies on a few isolated statements in the legislative history which do not support its conclusion, however favoringly read, I have deemed it necessary to set forth in an appendix, post, p. 485, the entire relevant legislative history of the Taft-Hartley Act and its predecessor, the Case Bill. This legislative history reinforces the natural meaning of the statute as an exclusively procedural provision, affording, that is, an accessible federal forum for suits on agreements between labor organizations and employers, but not enacting federal law for such suits. See also Wollett and Wellington, Federalism and Breach of the Labor Agreement, 7 Stan. L. Rev. 445.
I have also set forth in my opinion in the Westinghouse case an outline of the vast problems that the Court’s present decision creates by bringing into conflict state law and federal law, state courts and federal courts. 348 U. S., at 454-455; see also Judge Wyzanski’s opinion in Textile Workers Union v. American Thread Co., 113 F. Supp. 137, 140. These problems are not rendered non-existent by disregard of them. It should also be noted that whatever may be a union’s ad hoc benefit in a particular case, the meaning of collective bargaining for labor does not remotely derive from reliance on the sanction of litigation in the courts. Restrictions made by legislation like the Clayton Act of 1914, 38 Stat. 738, §§ 20, 22, and the Norris-LaGuardia Act of 1932, 47 Stat. 70, upon the use of familiar remedies theretofore available in the federal courts, reflected deep fears of the labor movement of the use of such remedies against labor. But a union, like any other combatant engaged in a particular fight, is ready to make an ally of an old enemy, *463and so we also find unions resorting to the otherwise much excoriated labor injunction. Such intermittent yielding to expediency does not change the fact that judicial intervention is ill-suited to the special characteristics of the arbitration process in labor disputes; nor are the conditions for its effective functioning thereby altered.
“The arbitration is an integral part of the system of self-government. And the system is designed to aid management in its quest for efficiency, to assist union leadership in its participation in the enterprise, and to secure justice for the employees. It is a means of making collective bargaining work and thus preserving private enterprise in a free government. When it works fairly well, it does not need the sanction of the law of contracts or the law of arbitration. It is only when the system breaks down completely that the courts’ aid in these respects is invoked. But the courts cannot, by occasional sporadic decision, restore the parties’ continuing relationship ; and their intervention in such cases may seriously affect the going systems of self-government. When their autonomous system breaks down, might not the parties better be left to the usual methods for adjustment of labor disputes rather than to court actions on the contract or on the arbitration award?” Shulman, Reason, Contract, and Law in Labor Relations, 68 Harv. L. Rev. 999, 1024.
These reflections summarized the vast and extraordinarily successful experience of Dean Harry Shulman as labor arbitrator, especially as umpire under the collective-bargaining contract between the Ford Motor Co. and the UAW-CIO. (See his Opinions of the Umpire, Ford Motor Co. and UAW-CIO, 1943-1946, and the review by E. Merrick Dodd in 60 Harv. L. Rev. 486.) Arbitration agreements are for specific terms, generally much shorter than the time required for adjudication of a con*464tested lawsuit through the available stages of trial and appeal. Renegotiation of agreements cannot await the outcome of such litigation; nor can the parties' continuing relation await it. Cases under § 301 will probably present unusual rather than representative situations. A “rule” derived from them is more likely to discombobulate than to compose. A “uniform corpus” cannot be expected to evolve, certainly not within a time to serve its assumed function.
The prickly and extensive problems that the supposed grant would create further counsel against a finding that the grant was made. They present hazardous opportunities for friction in the regulation of contracts between employers and unions. They involve the division of power between State and Nation, between state courts and federal courts, including the effective functioning of this Court. Wisdom suggests self-restraint in undertaking to solve these problems unless the Court is clearly directed to do so. Section 301 is not such a direction. The legislative history contains no suggestion that these problems were considered; the terms of the section do not present them.
One word more remains to be said. The earliest declaration of unconstitutionality of an act of Congress — by the Justices on circuit — involved a refusal by the Justices to perform a function imposed upon them by Congress because of the non-judicial nature of that function. Rayburn’s Case, 2 Dali. 409. Since then, the Court has many times declared legislation unconstitutional because it imposed on the Court powers or functions that were regarded as outside the scope of the “judicial power” lodged in the Court by the Constitution. See, e. g., Marburg v. Madison, 1 Cranch 137; United States v. Ferreira, 13 How. 40; Muskrat v. United States, 219 U. S. 346; Keller v. Potomac Electric Power Co., 261 U. S. 428.
One may fairly generalize from these instances that the Court has deemed itself peculiarly qualified, with due *465regard to the contrary judgment of Congress, to determine what is meet and fit for the exercise of “judicial power” as authorized by the Constitution. Solicitude and respect for the confines of “judicial power,” and the difficult problem of marking those confines, apply equally in construing precisely what duties Congress has cast upon the federal courts, especially when, as in this case, the most that can be said in support of finding a congressional desire to impose these “legislative” duties on the federal courts is that Congress did not mention the problem in the statute and that, insofar as purpose may be gathered from congressional reports and debates, they leave us in the dark.
The Court, however, sees no problem of “judicial power” in casting upon the federal courts, with no guides except “judicial inventiveness,” the task of applying a whole industrial code that is as yet in the bosom of the judiciary. There are severe limits on “judicial inventiveness” even for the most imaginative judges. The law is not a “brooding omnipresence in the sky,” (Mr. Justice Holmes, dissenting, in Southern Pacific Co. v. Jensen, 244 U. S. 205, 222), and it cannot be drawn from there like nitrogen from the air. These problems created by the Court's interpretation of § 301 cannot “be solved by resort to the established canons of construction that enable a court to look through awkward or clumsy expression, or language wanting in precision, to the intent of the legislature. For the vice of the statute here lies in the impossibility of ascertaining, by any reasonable test, that the legislature meant one thing rather than another . . . .” Connally v. General Construction Co., 269 U. S. 385, 394. But the Court makes § 301 a mountain instead of a molehill and, by giving an example of “judicial inventiveness,” it thereby solves all the constitutional problems that would otherwise have to be faced.
Even on the Court’s attribution to § 301 of a direction to the federal courts to fashion, out of bits and pieces *466elsewhere to be gathered, a federal common law of labor contracts, it still does not follow that Congress has enacted that an agreement to arbitrate industrial differences be specifically enforceable in the federal courts. On the contrary, the body of relevant federal law precludes such enforcement of arbitration clauses in collective-bargaining agreements.
Prior to 1925, the doctrine that executory agreements to arbitrate any kind of dispute would not be specifically enforced still held sway in the federal courts. See, e. g., Judge Hough’s opinion in United States Asphalt Refining Co. v. Trinidad Lake Petroleum Co., 222 F. 1006; Judge Mack’s opinion in Atlantic Fruit Co. v. Red Cross Line, 276 F. 319; and Mr. Justice Brandéis’ opinion in Red Cross Line v. Atlantic Fruit Co., 264 U. S. 109, 123, 125. Legislation was deemed necessary to assure such power to the federal courts. In 1925, Congress passed the United States Arbitration Act, 9 U. S. C. § 1 et seg., making executory agreements to arbitrate specifically enforceable in the federal courts, but explicitly excluding "contracts of employment” of workers engaged in interstate commerce from its scope. Naturally enough, I find rejection, though not explicit, of the availability of the Federal Arbitration Act to enforce arbitration clauses in collective-bargaining agreements in the silent treatment given that Act by the Court’s opinion. If an Act that authorizes the federal courts to enforce arbitration provisions in contracts generally, but specifically denies authority to decree that remedy for “contracts of employment,” were available, the Court would hardly spin such power out of the empty darkness of § 301. I would make this rejection explicit, recognizing that when Congress passed legislation to enable arbitration agreements to be enforced by the federal courts, it saw fit to exclude this remedy with respect to labor contracts. See Amalgamated Association v. Pennsylvania Greyhound *467Lines, 192 F. 2d 310 (C. A. 3d Cir.); United Electrical, Radio & Machine Workers v. Miller Metal Products, Inc., 215 F. 2d 221 (C. A. 4th Cir.); Lincoln Mills v. Textile Workers Union, 230 F. 2d 81 (C. A. 5th Cir.); United Steelworkers of America v. Galland-Henning Mfg. Co., 241 F. 2d 323 (C. A. 7th Cir.); and the legislative history-set forth by the parties in the present cases. Congress heeded the resistance of organized labor, uncompromisingly led in its hostility to this measure by Andrew Furuseth, president of the International Seamen’s Union and most powerful voice expressing labor’s fear of the use of this remedy against it.2
Even though the Court glaringly ignores the Arbitration Act, it does at least recognize the common-law rule against enforcement of executory agreements to arbitrate. It nevertheless enforces the arbitration clause in the collective-bargaining agreements in these cases. It does so because it finds that Congress “by implication” rejected the common-law rule. I would add that the Court, in thus deriving power from the unrevealing words of the Taft-Hartley Act, has also found that Congress “by implication” repealed its own statutory exemption of collective-bargaining agreements in the Arbitration Act, an *468exemption made as we have seen for well-defined reasons of policy.
The Court of Appeals for the First Circuit, which reached the conclusion that arbitration clauses in collective-bargaining agreements were enforceable under the Arbitration Act, nevertheless found that such clauses would not have been enforceable by virtue of § 301:
“A number of courts have held that § 301 itself is a legislative authorization for decrees of specific performance of arbitration agreements. ... We think that is reading too much into the very general language of § 301. The terms and legislative history of § 301 sufficiently demonstrate, in our view, that it was not intended either to create any new remedies or to deny applicable existing remedies. See H. R. Rep. No. 245, 80th Cong., 1st Sess. 46 (1947); H. R. Rep. No. 510 (Conference Report), 80th Cong., 1st Sess. 42 (1947); 93 Cong. Rec. 3734, 6540 (daily ed. 1947). Arbitration was scarcely mentioned at all in the legislative history. Furthermore, the same practical consideration that militates against judicial overruling of the common law doctrine applies against interpreting § 301 to give that effect. The most that could be read into it would be that it authorizes equitable remedies in general, including decrees for specific performance of an arbitration agreement. Lacking are the procedural specifications needed for administration of the power to compel arbitration. . . . Thus it seems to us that a firmer statutory basis than § 301 should be found to justify departure from the judicially formulated doctrines with reference to arbitration agreements.” Local 205 v. General Electric Co., 233 F. 2d 85, 96-97.
I would put the conclusion even more strongly because, contrary to the view of the Court of Appeals for the First Circuit, the rule that is departed from “by implication” *469had not only been “judicially formulated” but had purposefully been congressionally formulated in the Arbitra-' tion Act of 1925. And it is being departed from on the tenuous basis of the legislative history of § 301, for which the utmost that can be claimed is that insofar as there was any expectation at all, it was only that conventional remedies, including equitable remedies, would be available. But of course, as we have seen, “equitable remedies” in the federal courts had traditionally excluded specific performance of arbitration clauses, except as explicitly provided by the 1925 Act. Thus, even assuming that § 301 contains directions for some federal substantive law of labor contracts, I see no justification for translating the vague expectation concerning the remedies to be applied into an overruling of previous federal common law and, more particularly, into the repeal of the previous congressional exemption of collective-bargaining agreements from the class of agreements in which arbitration clauses were to be enforced.
The second ground of my dissent from the Court’s action is more fundamental.3 Since I do not agree with the Court’s conclusion that federal substantive law is to govern in actions under § 301,1 am forced to consider the serious constitutional question that was adumbrated in the Westinghouse case, 348 U. S., at 449-452, the constitutionality of a grant of jurisdiction to federal courts over contracts that came into being entirely by virtue of state substantive law, a jurisdiction not based on diversity of citizenship, yet one in which a federal court would, as in *470diversity cases, act in effect merely as another court of the State in which it sits. The scope of allowable federal judicial power that this grant must satisfy is constitutionally described as “Cases, in Law and Equity, arising under this Constitution, the Laws of the United States, and Treaties made, or which shall be made, under their Authority.” Art. Ill, § 2. ' While interpretive decisions are legion under general statutory grants of jurisdiction strikingly similar to this constitutional wording, it is generally recognized that the full constitutional power has not been exhausted by these statutes. See, e. g., Mish-kin, The Federal “Question” in the District Courts, 53 Col. L. Rev. 157, 160; Shulman and Jaegerman, Some Jurisdictional Limitations on Federal Procedure, 45 Yale L. J. 393, 405, n. 47; Wechsler, Federal Jurisdiction and the Revision of the Judicial Code, 13 Law & Contemp. Prob., 216, 224-225.
Almost without exception, decisions under the general statutory grants have tested jurisdiction in terms of the presence, as an integral part of plaintiff’s cause of action, of an issue calling for interpretation or application of federal law. E. g., Gully v. First National Bank, 299 U. S. 109. Although it has sometimes been suggested that the “cause of action” must derive from federal law, see American Well Works Co. v. Layne & Bowler Co., 241 U. S. 257, 260, it has been found sufficient that some aspect of federal law is essential to plaintiff’s success. Smith v. Kansas City Title & Trust Co., 255 U. S. 180. The litigation-provoking problem has been the degree to which federal law must be in the forefront of the case and not collateral, peripheral or remote.
In a few exceptional cases, arising under special jurisdictional grants, the criteria by which the prominence of the federal question is measured against constitutional requirements have been found satisfied under circumstances suggesting a variant theory of the nature of these *471requirements. The first, and the leading case in the field, is Osborn v. Bank of the United States, 9 Wheat. 738. There, Chief Justice Marshall sustained federal jurisdiction in a situation — hypothetical in the case before him but presented by the companion case of Bank of the United States v. Planters’ Bank, 9 Wheat. 904—involving suit by a federally incorporated bank upon a contract. Despite the assumption that the cause of action and the interpretation of the contract would be governed by state law, the case was found to “arise under the laws of the United States” because the propriety and scope of a federally granted authority to enter into contracts and to litigate might well be challenged. This reasoning was subsequently applied to sustain jurisdiction in actions against federally chartered railroad corporations. Pacific Railroad Removal Cases, 115 U. S. 1. The traditional interpretation of this series of cases is that federal jurisdiction under the “arising” clause of the Constitution, though limited to cases involving potential federal questions, has such flexibility that Congress may confer it whenever there exists in the background some federal proposition that might be challenged, despite the remoteness of the likelihood of actual presentation of such a federal question.4
The views expressed in Osborn and the Pacific Railroad Removal Cases were severely restricted in construing general grants of jurisdiction. But the Court later sustained this jurisdictional section of the Bankruptcy Act of 1898:
“The United States district courts shall have jurisdiction of all controversies at law and in equity, as distinguished from proceedings in bankruptcy, be*472tween trustees as such and adverse claimants concerning the property acquired or claimed by the trustees, in the same manner and to the same extent only as though bankruptcy proceedings had not been instituted and such controversies had been between the bankrupts and such adverse claimants.” § 23 (a), as amended, 44 Stat. 664.
Under this provision the trustee could pursue in a federal court a private cause of action arising under and wholly governed by state law. Schumacher v. Beeler, 293 U. S. 367; Williams v. Austrian, 331 U. S. 642 (Chandler Act of 1938, 52 Stat. 840). To be sure, the cases did not discuss the basis of jurisdiction. It has been suggested that they merely represent an extension of the approach of the Osborn case; the trustee’s right to sue might be challenged on obviously federal grounds — absence of bankruptcy or irregularity of the trustee’s appointment or of the bankruptcy proceedings. National Mutual Ins. Co. v. Tidewater Transfer Co., 337 U. S. 582, 611-613 (Rutledge, J., concurring). So viewed, this type of litigation implicates a potential federal question.
Apparently relying on the extent to which the bankruptcy cases involve only remotely a federal question, Mr. Justice Jackson concluded in National Mutual Insurance Co. v. Tidewater Transfer Co., 337 U. S. 582, that Congress may confer jurisdiction on the District Courts as incidental to its powers under Article I. No attempt was made to reconcile this view with the restrictions of Article III; a majority of the Court recognized that Article III defined the bounds of valid jurisdictional legislation and rejected the notion that jurisdictional grants can go outside these limits.
With this background, many theories have been proposed to sustain the constitutional validity of § 301. In Textile Workers Union of America v. American Thread Co., 113 F. Supp. 137, 140, Judge Wyzanski suggested, *473among other possibilities, that § 301 might be read as containing a direction that controversies affecting interstate commerce should be governed by federal law incorporating state law by reference, and that such controversies would then arise under a valid federal law as required by Article III. Whatever may be said of the assumption regarding the validity of federal jurisdiction under an affirmative declaration by Congress that state law should be applied as federal law by federal courts to contract disputes affecting commerce, we cannot argumentatively legislate for Congress when Congress has failed to legislate. To do so disrespects legislative responsibility and disregards judicial limitations.
Another theory, relying on Osborn and the bankruptcy cases, has been proposed which would achieve results similar to those attainable under Mr. Justice Jackson's view, but which purports to respect the “arising” clause of Article III. See Hart and Wechsler, The Federal Courts and the Federal System, pp. 744-747; Wechsler, Federal Jurisdiction and the Revision of the Judicial Code, 13 Law & Contemp. Prob. 216, 224-225; International Brotherhood v. W. L. Mead, Inc., 230 F. 2d 576. Called “protective jurisdiction,” the suggestion is that in any case for which Congress has the constitutional power to prescribe federal rules of decision and thus confer “true” federal question jurisdiction, it may, without so doing, enact a jurisdictional statute, which will provide a federal forum for the application of state statute and decisional law. Analysis of the “protective jurisdiction” theory might also be attempted in terms of the language of Article III — construing “laws” to include jurisdictional statutes where Congress could have legislated substantively in a field. This is but another way of saying that because Congress could have legislated substantively and thereby could give rise to litigation under a statute of the United States, it can provide a federal forum for state-*474created rights although it chose not to adopt state law as federal law or to originate federal rights.
Surely the truly technical restrictions of Article III are not met or respected by a beguiling phrase that the greater power here must necessarily include the lesser. In the compromise of federal and state interests leading to distribution of jealously guarded judicial power in a federal system, see 13 Cornell L. Q. 499, it is obvious that very different considerations apply to cases involving questions of federal law and those turning solely on state law. It may be that the ambiguity of the phrase “arising under the laws of the United States” leaves room for more than traditional theory could accommodate. But, under the theory of “protective jurisdiction,” the “arising under” jurisdiction of the federal courts would be vastly extended. For example, every contract or tort arising out of a contract affecting commerce might be a potential cause of action in the federal courts, even though only state law was involved in the decision of the case. At least in Osborn and the bankruptcy cases, a substantive federal law was present somewhere in the background. See pp. 470-472, supra, and pp. 480-484, infra. But this theory rests on the supposition that Congress could enact substantive federal law to govern the particular case. It was not held in those cases, nor is it clear, that federal law could be held to govern the transactions of all persons who subsequently become bankrupt, or of all suits of a Bank of the United States. See Mishkin, The Federal “Question” in the District Courts, 53 Col. L. Rev. 157,189.
“Protective jurisdiction,” once the label is discarded, cannot be justified under any view of the allowable scope to be given to Article III. “Protective jurisdiction” is a misused label for the statute we are here considering. That rubric is properly descriptive of safeguarding some of the indisputable, staple business of the federal courts. It is a radiation of an existing jurisdiction. See Adams v. *475United States ex rel. McCann, 317 U. S. 269; 28 U. S. C. i 2283. “Protective jurisdiction.” cannot generate an independent source for adjudication outside of the Article III sanctions and what Congress has defined. The theory-must have as its sole justification a belief in the inadequacy of state tribunals in determining state law. The Constitution reflects such a belief in the specific situation within which the Diversity Clause was confined. The intention to remedy such supposed defects was exhausted in this provision of Article III.5 That this “protective” theory was not adopted by Chief Justice Marshall at a time when conditions might have presented more substantial justification strongly suggests its lack of constitutional merit. Moreover, Congress in its consideration of § 301 nowhere suggested dissatisfaction with the ability of state courts to administer state law properly. Its concern was to provide access to the federal courts for easier enforcement of state-created rights.
Another theory also relies on Osborn and the bankruptcy cases as an implicit recognition of the propriety of the exercise of some sort of “protective jurisdiction” by the federal courts. Mishkin, op. cit. supra, 53 Col. L. Rev. 157, 184 et seq. Professor Mishkin tends to view the assertion of such a jurisdiction, in the absence of any *476exercise of substantive powers, as irreconcilable with the “arising” clause since the case would then arise only under the jurisdictional statute itself, and he is reluctant to find a constitutional basis for the grant of power outside Article III. Professor Mishkin also notes that the only purpose of such a statute would be to insure impartiality to some litigant, an objection inconsistent with Article Ill’s recognition of “protective jurisdiction” only in the specified situation of diverse citizenship. But where Congress has “an articulated and active federal policy regulating a field, the 'arising under’ clause of Article III apparently permits the conferring of jurisdiction on the national courts of all cases in the area — including those substantively governed by state law.” Id,., at 192. In such cases, the protection being offered is not to the suitor, as in diversity cases, but to the “congressional legislative program.” Thus he supports § 301: “even though the rules governing collective bargaining agreements continue to be state-fashioned, nonetheless the mode of their application and enforcement may play a very substantial part in the labor-management relations of interstate industry and commerce — an area in which the national government has labored long and hard.” Id., at 196.
Insofar as state law governs the case, Professor Mish-kin’s theory is quite similar to that advanced by Professors Hart and Wechsler and followed by the Court of Appeals for the First Circuit: The substantive power of Congress, although not exercised to govern the particular “case,” gives “arising under” jurisdiction to the federal courts despite governing state law. The second “protective jurisdiction” theory has the dubious advantage of limiting incursions on state judicial power to situations in which the State’s feelings may have been tempered by early substantive federal invasions.
Professor Mishkin’s theory of “protective jurisdiction” may find more constitutional justification if there is not *477merely an “articulated and active” congressional policy regulating the labor field but also federal rights existing in the interstices of actions under § 301. See Wollett' and Wellington, Federalism and Breach of the Labor Agreement, 7 Stan. L. Rev. 445, 475-479. Therefore, before resting on an interpretation of § 301 that would compel a declaration of unconstitutionality, we must, as was stated in Westinghouse, defer to the strong presumption — even as to such technical matters as federal jurisdiction — that Congress legislated in accordance with the Constitution. The difficult nature of the problem of construction to be faced if some federal rights are sought was set forth in Westinghouse, where the constitutional questions were involved only in their bearing on the construction of the statute. Now that the constitutional questions themselves must be faced, the nature of the problem bears repeating.
Legislation must, if possible, be given a meaning that will enable it to survive. This rule of constitutional adjudication is normally invoked to narrow what would otherwise be the natural but constitutionally dubious scope of the language. E. g., United States v. Delaware & Hudson Co., 213 U. S. 366; United States v. Jin Fuey Moy, 241 U. S. 394, 401; United States v. Rumely, 345 U. S. 41. Here the endeavor of some lower courts and of this Court has resulted in adding to the section substantive congressional regulation even though Congress saw fit not to exercise such power or to give the courts any concrete guidance for defining such regulation.
To be sure, the full scope of a substantive regulation is frequently in dispute and must await authoritative determination by courts. Congress declares its purpose imperfectly or partially, and compatible judicial construction completes it. But in this case we start with a provision that is wholly jurisdictional and as such bristles with constitutional problems under Article III. To avoid *478them, interpolation of substantive regulation has been proposed. From what materials are we to draw a determination that § 301 is something other than what it declares itself? Is the Court justified in creating all the difficult problems of choice within a sphere of delicate policy without any direction from Congress and merely for the sake of giving effect to a provision that seems to deal with a different subject? The somewhat Delphic wisdom of Mr. Justice Cardozo, speaking for the whole Court, pulls us here in the opposite direction: “We think the light is so strong as to flood whatever places in the statute might otherwise be dark. Courts have striven mightily at times to canalize construction along the path of safety. . . . When a statute is reasonably susceptible of two interpretations, they have preferred the meaning that preserves to the meaning that destroys. . . . ‘But avoidance of a difficulty will not be pressed to the point of disingenuous evasion.’ . . . ‘Here the intention of the Congress is revealed too distinctly to permit us to ignore it because of mere misgivings as to power.’ ” Hopkins Federal Savings & Loan Assn. v. Cleary, 296 U. S. 315, 334-335.
Assuming, however, that we would be justified in pouring substantive content into a merely procedural vehicle, what elements of federal law could reasonably be put into the provisions of § 301? The suggestion that the section permits the federal courts to work out, without more, a federal code governing collective-bargaining contracts must, for reasons that have already been stated, be rejected. Likewise the suggestion that § 301 may be viewed as a congressional authorization to the federal courts to work out a concept of the nature of the collective-bargaining contract, leaving detailed questions of interpretation to state law. See 348 U. S., at 455-459.
Nor will Congress’ objective be furthered by an attempt to limit the grant of a federal forum to certain types of *479actions between unions and employers. It would be difficult to find any basis for, or principles of, selection, either in the terms of § 301 or in considerations relevant to promotion of stability in labor relations. It is true that a fair reading of § 301 in the context of its enactment shows that the suit that Congress primarily contemplated was the suit against a union for strike in violation of contract. From this it might be possible to imply a federal right to bring an action for damages based on such an event. In the interest of mutuality, so close to the heart of Congress, we might in turn find a federal right in the union to sue for a lockout in violation of contract. But neither federal right would be involved in the present cases. Moreover, it bears repetition that Congress chose not to make this the basis of federal law, i. e., it chose not to make such conduct an unfair labor practice.
There is a point, however, at which the search may be ended with less misgiving regarding the propriety of judicial infusion of substantive provisions into § 301. The contribution of federal law might consist in postulating the right of a union, despite its amorphous status as an unincorporated association, to enter into binding collective-bargaining contracts with an employer. The federal courts might also give sanction to this right by refusing to comply with any state law that does not admit that collective bargaining may result in an enforceable contract. It is hard to see what serious federal-state conflicts could arise under this view. At most, a state court might dismiss the action, while a federal court would entertain it. Moreover, such a function of federal law is closely related to the removal of the procedural barriers to suit. Section 301 would be futile if the union’s status as a contracting party were not recognized. The statement in § 301 (b) that the acts of the agents of the union are to be regarded as binding upon the union may be used in support of this conclusion. This provision, *480not confined in its application to suits in the District Court under § 301 (a), was primarily directed to responsibility of the union for its agents' actions in authorizing strikes or committing torts. It can be construed, however, as applicable to the formation of a contract. So applied, it would imply that a union must be regarded as contractually bound by the acts of its agents, which in turn presupposes that the union is capable of contract relations.
Of course, the possibility of a State’s law being counter to such a limited federal proposition is hypothetical, and to base an assertion of federal law on such a possibility, one never considered by Congress, is an artifice. And were a State ever to adopt a contrary attitude, its reasons for so doing might be such that Congress would not be willing to disregard them. But these difficulties are inherent in any attempt to expand § 301 substantively to meet constitutional requirements.
Even if this limited federal “right” were read into § 301, a serious constitutional question would still be present. It does elevate the situation to one closely analogous to that presented in Osborn v. Bank of the United States, 9 Wheat. 738.6 Section 301 would, under this view, imply that a union is to be viewed as a juristic entity for purposes of acquiring contract rights under a collective-bargaining agreement, and that it has the right to enter into such a contract and to sue upon it. This was all that was immediately and expressly involved in the Osborn case, although the historical setting was *481vastly different, and the juristic entity in that case was completely the creature of federal law, one engaged in carrying out essential governmental functions. Most of these special considerations had disappeared, however, at the time and in the circumstances of the decision of the Pacific Railroad Removal Cases, 115 U. S. 1, see p. 471, supra. There is force in the view that regards the latter as a “sport” and finds that the Court has so viewed it. See Mishkin, 53 Col. L. Rev., at 160, n. 24, citing Gully v. First National Bank, 299 U. S. 109, 113-114 (“Only recently we said after full consideration that the doctrine of the charter cases was to be treated as exceptional, though within their special field there was no thought to disturb them.”), and Puerto Rico v. Russell & Co., 288 U. S. 476, 485; see also Mr. Justice Holmes, in Smith v. Kansas City Title & Trust Co., 255 U. S. 180, 214-215 (dissenting opinion). The question is whether we should now so consider it and refuse to apply its holding to the present situation.
I believe that we should not extend the precedents of Osborn and the Pacific Railroad Removal Cases to this case, even though there be some elements of analytical similarity. Osborn, the foundation for the Removal Cases, appears to have been based on premises that today, viewed in the light of the jurisdictional philosophy of Gully v. First National Bank, supra, are subject to criticism. The basic premise was that every case in which a federal question might arise must be capable of being commenced in the federal courts, and when so commenced it might, because jurisdiction must be judged at the outset, be concluded there despite the fact that the federal question was never raised. Marshall’s holding was undoubtedly influenced by his fear that the bank might suffer hostile treatment in the state' courts that could not be remedied by an appeal on an isolated federal question. There is nothing in Article III that affirmatively supports the view that original jurisdiction over cases involving *482federal questions must extend to every case in which there is the potentiality of appellate jurisdiction. We also have become familiar with removal procedures that could be adapted to alleviate any remaining fears by providing for removal to a federal court whenever a federal question was raised. In view of these developments, we would not be justified in perpetuating a principle that permits assertion of original federal jurisdiction on the remote possibility of presentation of a federal question. Indeed, Congress, by largely withdrawing the jurisdiction that the Pacific Railroad Removal Cases recognized, and this Court, by refusing to perpetuate it under general grants of jurisdiction, see Gully v. First National Bank, supra, have already done much to recognize the changed atmosphere.
Analysis of the bankruptcy power also reveals a superficial analogy to § 301. The trustee enforces a cause of action acquired under state law by the bankrupt. Federal law merely provides for the appointment of the trustee, vests the cause of action in him, and confers jurisdiction on the federal courts. Section 301 similarly takes the rights and liabilities which under state law are vested distributively in the individual members of a union and vests them in the union for purposes of actions in federal courts, wherein the unions are authorized to sue and be sued as an entity. While the authority of the trustee depends on the existence of a bankrupt and on the propriety of the proceedings leading to the trustee’s appointment, both of which depend on federal law, there are similar federal propositions that may be essential to an action under § 301. Thus, the validity of the contract may in any case be challenged on the ground that the labor organization negotiating it was not the representative of the employees concerned, a question that has been held to be federal, La Crosse Telephone Corp. v. Wisconsin Employment Relations Board, 336 U. S. 18, or on the ground that subsequent change in the representa*483tive status of the union has affected the continued validity of the agreement. Perhaps also the qualifications imposed on a union’s right to utilize the facilities of the National Labor Relations Board, dependent on the filing of non-Communist affidavits required by § 9 (h) and the information and reports required by § 9 (f) and (g), might be read as restrictions on the right of the union to sue under § 301, again providing a federal basis for challenge to the union’s authority. Consequently, were the bankruptcy cases to be viewed as dependent solely on the background existence of federal questions, there would be little analytical basis for distinguishing actions under § 301. But the bankruptcy decisions may be justified by the scope of the bankruptcy power, which may be deemed to sweep within its scope interests analytically outside the “federal question” category, but sufficiently related to the main purpose of bankruptcy to call for comprehensive treatment. See National Mutual Ins. Co. v. Tidewater Transfer Co., 337 U. S. 582, 652, n. 3 (concurring in part, dissenting in part). Also, although a particular suit may be brought by a trustee in a district other than the one in which the principal proceedings are pending, if all the suits by the trustee, even though in many federal courts, are regarded as one litigation for the collection and apportionment of the bankrupt’s property, a particular suit by the trustee, under state law, to recover a specific piece of property might be analogized to the ancillary or pendent jurisdiction cases in which, in the disposition of a cause of action, federal courts may pass on state grounds for recovery that are joined to federal grounds. See Hurn v. Oursler, 289 U. S. 238; Siler v. Louisville & Nashville R. Co., 213 U. S. 175; but see Mishkin, 53 Col. L. Rev., at 194, n. 161.
If there is in the phrase “arising under the laws of the United States” leeway for expansion of our concepts of jurisdiction, the history of Article III suggests that the area is not great and that it will require the presence of *484some substantial federal interest, one of greater weight and dignity than questionable doubt concerning the effectiveness of state procedure. The bankruptcy cases might possibly be viewed as such an expansion. But even so, not merely convenient judicial administration but the whole purpose of the congressional legislative program — conservation and equitable distribution of the bankrupt’s estate in carrying out the constitutional power over bankruptcy — required the availability of federal jurisdiction to avoid expense and delay. Nothing pertaining to § 301 suggests vesting the federal courts with sweeping power under the Commerce Clause comparable to that vested in the federal courts under the bankruptcy power.
In the wise distribution of governmental powers, this Court cannot do what a President sometimes does in returning a bill to Congress. We cannot return this provision to Congress and respectfully request that body to face the responsibility placed upon it by the Constitution to define the jurisdiction of the lower courts with some particularity and not to leave these courts at large. Confronted as I am, I regretfully have no choice. For all the reasons elaborated in this dissent, even reading into § 301 the limited federal rights consistent with the purposes of that section, I am impelled to the view that it is unconstitutional in cases such as the present ones where it provides the sole basis for exercise of jurisdiction by the federal courts.7
*485APPENDIX — LEGISLATIVE HISTORY.
I.The Case Bill (H. R. 4908, 79th Cong., 2d Sess.).
(The Federal Mediation Act of 1946.)
A. Legislative history in the House:
1. Hearings before the Committee on Labor on H. R.
4908, 79th Cong., 1st Sess.:
a. H. R. 4908, as considered by committee, provided for fact-finding boards. It had no provision concerning suits on collective-bargaining contracts.
b. During these hearings, there was, however, some concern with breach of such contracts. Despite the filing of two memoranda detailing the problems of enforcement of agreements against a union (pp. 89, 96), there was no elucidation of the problem. The prevalence of violation was noted and the desire to do something to promote enforceability expressed. (Pp. 15, 27, 28, 38, 41, 68, 73, 84, 88, 97, 101, 113.)
2. The House Report contained no comment on the problem. (H. R. Rep. No. 1493, 79th Cong., 2d'Sess.)
3. The bill, as introduced on the House floor (92 Cong. Rec. 765):
“See. 10. Binding effect of collective-bargaining contracts: All collective-bargaining contracts shall be mutually and equally binding and enforceable either at law or in equity against each of the parties thereto, any other law to the contrary notwithstanding. In the event of a breach of any such contract or of any agreement contained in such contract by either party thereto, then, in addition to any other remedy or remedies existing either in law or equity, a suit for damages for such breach or for *486injunctive relief in equity may be maintained by the other party or parties in any United States district court having jurisdiction of the parties. If the defendant against whom action is sought to be commenced and maintained is a labor organization, such action may be filed in the United States district court of any district wherein any officer of such labor organization resides or may be found.”
4. House debate:
a. General comment on the desirability of mutual enforceability of contracts: 92 Cong. Rec. 662, 668, 677, 679, 684, 686, 753, 767.
b. Representative Francis Case’s only comments were not pertinent. Id., at 680, 765.
c. Representative Vorys, in offering corrective amendments to Section 10, stated:
“We do create, if there is any doubt about its present existence, an action for damages for breach of contract against a labor organization or an employer, which means that either party, the labor organization or the employer, may have the benefit of a trial by jury in any such action.
“. . . Since we are attempting to create no new right in the equity side, there is no reason to refer to the equity side ....
“. . . It will take away any particular benefits or advantages of one party or the other that now exist under other laws which keep the obligations from being equal and mutual; will not give any new rights by way of injunction to either party but will specifically provide for an action at law for damages to enforce any act of violation of the contracts.” {Id., at 853.)
*487d. Representative Thom, opposing Section 10 as an incursion on States’ rights, appears to have been the only member to have felt that collective bargaining contracts already were enforceable in state and federal courts. Id., at 847.
5. As it finally passed the House, Section 10 read:
“Sec. 10. Binding effect of collective-bargaining contracts. — All collective-bargaining contracts shall be mutually and equally binding and enforceable against each of the parties thereto, any other law to the contrary notwithstanding. In the event of a breach of any such contract or of any agreement contained in such contract by either party thereto, then, in addition to any other remedy or remedies existing, a suit for damages for such breach may be maintained by the other party or parties in any State or United States district court having jurisdiction of the parties.”
B. Legislative history in the Senate:
1. Hearings before Senate Committee on Education and Labor on S. 1661:
a. Hearings were held on a companion bill to the fact-finding bill on which House hearings were held. The Case bill had not yet passed the House.
b. As in the House, however, concern was expressed over a general impression that unions were not subject to suits for damages for breach of contract to the same extent as employers. (Pp. 138, 168, 354, 383, 400, 554, 623, 662, 740.) For the first time, however, oral testimony directed the legislators to the primary source of the problem. This testimony, with a supporting memorandum, indicated that the problem lay in the status of the union *488as an unincorporated association. This memorandum, however, also pointed out that in some jurisdictions the union was viewed as acting as agent of the individual employees in negotiating the collective agreement, and thus was not viewed as having, even in theory, any rights or obligations on the contract. (P. 411.)
2. Hearings before a Subcommittee of the Senate Committee on Education and Labor on H. R. 4908 (as it had passed the House):
a. “Mr. CASE. Section 10, opening the miscellaneous provisions of the bill, is very brief, and I would like to read it because I think it speaks for itself.
“It almost would seem unnecessary to say that contracts entered into between two parties call for mutual obligations and mutual observance. That is implicit in all contracts, whether expressed or not, by statutory provisions saying they are equally binding and enforceable; but because of some interpretations or some theories that they are not binding where labor organizations are involved, I thought in harmony with what the President said here — recognizing a practical situation for which we have to find methods not only of peaceful negotiation but also of insuring that the contracts once made must be lived up to — we should have a section in the bill on that subject.
“This section was modified somewhat in the consideration in the House. Originally I think we had in a provision authorizing restraining orders, but that was eliminated . . . with the consent of myself and others who had been studying the bill, with the thought that this possibly met the situation by authorizing a suit for damages for breach of contract.
*489“Senator TAFT. Mr. Case, there are one or two minor questions on that. It says:
“All collective-bargaining contracts shall be . . . enforceable by a suit in a State or a United States district court having jurisdiction of the parties.
“Would you intend to give jurisdiction to the United States district court in purely local collective-bargaining contracts not dealing with interstate commerce? Ought not that be limited in some way?
“Mr. CASE. That may be. There are other places in the bill where we worked in, first of all, a declaration of public interest, and my thought there was that resting on the general welfare clause, it was clearly within the authority of Congress where substantial public interest was involved to take cognizance—
“Senator TAFT ... I would think that probably the jurisdiction of the United States court should be confined to the type of dispute which is interstate in character and under the jurisdiction of the National Labor Relations Board.
“Mr. CASE. I certainly would have no objection to a clarification on that point. . . .
“Of course, the Senator is aware of the fact that the interpretation of the Supreme Court recently, on the subject of interstate commerce, has been so broad that anything which affects interstate commerce, which is technically interstate commerce has been ruled to be interstate commerce.
“Senator TAFT. On the other hand, there is still a field of intrastate commerce. It doesn't destroy it, although it goes a long way.
“Mr. CASE. As far as I am concerned, I would be glad to protect that vanishing field of intrastate *490commerce, and if the Senators wanted to clarify that I would have no objection.
“Senator TAFT. The other question relating to that section which occurs to me is the effect of this 'binding and enforceable/ as related to the incorporation of unions. As I understand it, a collective-bargaining agreement is already mutually and equally binding and enforceable. I can't think of any circumstance where it would not be. But the problem seems to be a practical problem, in many States, of successfully suing a union which is not incorporated. I don’t take it that this section would change the requirements in a State, we will say, to make every member of the union a party. It doesn’t really meet that particular difficulty, which seems to be the chief difficulty in enforcing collective-bargaining agreements.
“Mr. CASE. I think that what this would do would be to make the officers of a collective-bargaining agent suable. I do not think it would extend to individual members of the union, because the language is that the contract is made ‘mutually and equally binding and enforceable against each of the parties thereto’ and under the Wagner Act the party to the contract is the recognized bargaining agent.
“Senator TAFT. No; the recognized bargaining agent is the union, not the officers of the union; it is the union, and the union is usually an unincorporated association. The point I was trying to make is that if you want to sue an unincorporated association in many States it is almost impossible to get them into court, because they have requirements that you have to serve every member, and you can’t reach them, you can’t find them in many cases. So *491the whole thing is delayed, and it is a long and tedious problem, if it can be done at all. In some States that is not so. You can sue an unincorporated association by serving the officers. But we have before us a bill from Senator Byrd requiring that unions be incorporated for the purpose of carrying out, as I see it, the same purpose you have here, at least partially, and I just wondered whether this really was effective to meet the actual difficulty today in enforcing collective-bargaining agreements.
“Mr. CASE. Well, the intent of it is to make it possible to bring the action against the union in the common name of the association.
“Senator TAFT. I don’t say it doesn’t have that effect, but I don’t think-it does. I don’t think that ‘other law to the contrary notwithstanding’ would affect the method by which you had to bring a suit against an unincorporated association.
“Senator BALL. Would that make it possible to sue the union as an entity in the Federal court by simply serving the officers?
“Senator TAFT. I don’t think so, unless you said so. You might conceivably say so.
“Senator BALL. Then the other question is: Could we, in effect, waive State laws and make the same provision apply in State courts?
“Senator TAFT. No; I don’t think you can. But this would authorize suit to be brought in the Federal court and I thought that should be confined to interstate cases.
“Mr. CASE. Following the procedure probably, however, of the law of the State in which the action was brought.
“Senator TAFT. I don’t know; that is a complicated question, as you know, in a Federal court as *492to when you have to comply with the State law and when you do not.
“Mr. CASE. The Senator is probably more familiar than I with what is called the Second Coronado case. I am not familiar with the details of it, but as I have read references to it I think there the Supreme Court held that an injunction could be obtained against a union as such where the United States was the party. Now of course, this section doesn’t carry any injunctive procedure; but there, at least, the Supreme Court seemed to recognize that a union might be made the object of an action as an association without reaching the individual members.
“Senator TAFT. This would carry to a civil injunction process if it were one generally usable under laws of equity, I think, when you say it is binding and enforceable; whatever the equitable remedies might be in that State, or might be considered proper by the court, could be used.
“Senator SMITH. I would like to ask Mr. Case one question on section 10. I have difficulty in seeing how that changes what the situation would be if it just wasn’t in there at all. I don’t quite see why we need to put that in this bill.
“Let me say first that I have not studied this carefully, so I am raising the question as it comes to me.
“Mr. CASE. The intent primarily was to meet the technical legal difficulty that at the present time the union isn’t suable or actionable as an association unless it is incorporated, and to avoid the necessity of joining all members of the union as parties.
“Senator TAFT. I would suggest if that is your purpose it ought to say so in so many words.
*493"Mr. CASE. I appreciate the Senator’s suggestion.
“Senator SMITH. That was my difficulty. It didn’t seem to me it did make that clear, if that is the intent.” (Pp. 8-11.)
b. The technical, procedural nature of the problem was also stressed in testimony of some other witnesses. See pp. 175-179; 198-200; 248-249.
c. Other less discerning discussion: pp. 34, 47, 48, 110, 125, 129, 135, 144, 148, 157, 225, 237, 240, 266, 371, 372, 378, 385, 409.
3. Senate Report (No. 1177, 79th Cong., 2d Sess.):
a. Majority:
“Your committee has also considered and rejected section 10 of H. R. 4908, as passed by the House, which would explicitly declare that all collective-bargaining contracts shall be mutually binding and enforceable by the parties thereto. In the first place, this proposal appears to be based upon a misapprehension as to the legal responsibility of the parties under such contracts. Collective-bargaining agreements are at present legally enforceable in the courts, and in the Federal courts, if jurisdiction is otherwise established according to applicable law, unions may be sued in their own names under the doctrine of the first Coronado case (United Mine Workers v. Coronado Coal Company, 259 U. S. [344]). Legally, therefore, the proposed provision is unnecessary. Practically, it presents serious dangers. By offering easy access to the courts in cases where a breach of a collective-bargaining agreement is alleged, it would act as an inducement to litigate every alleged grievance, and would result in a flood of litigation making the courts again the battlefield *494for industrial disputes, increasing rather than eliminating the acrimony and conflict between the parties. In addition, your committee wishes to point out the fallacy of a widely held notion that breaches of contract are most often committed by labor organizations and employees. On the contrary, most breaches of contract are by employers. As has been elsewhere stated at greater length in this report your committee feels that labor disputes should be settled by conference, negotiation, and compromise, and not by the use of mandatory judicial processes. . . (Pp. 8-9.)
b. Minority (Senators Ball, Taft, and H. Alexander Smith):
“Amendment No. 3 [the minority proposal] would make unions suable as legal entities in the Federal courts for violation of contract, with liability limited to union assets and not enforceable against individual members or their property. A subsection would provide that where individual employees participated in a ‘wildcat’ strike in violation of contract, not sanctioned or approved by the union, the union itself would not be liable but such employees would lose their legal status as employees under the'Wagner Act, leaving the employer free to discharge them or not. While collective-bargaining agreements theoretically are legally enforceable contracts, as a practical matter, because of the many obstacles to suits against unions imposed by most States, they are actually binding on only one party, the employer. The minority believes this provision, imposing equal responsibility on both parties to such contracts, is absolutely essential to the stability of labor relations. The only argument so far advanced against it is that some employers might embarrass *495unions by suits for enforcement of contract. This hardly is a valid ground for continuing to regard such contracts as one-way arrangements, wherein one party receives benefits and assumes no binding obligations whatsoever.” (Pp. 3-4.)
“Text of Amendment No. 3
“Amend H. R. 4908 by inserting at the proper place the following new section:
“Sec. —. (a) Suits for violation of a contract concluded as the result of collective bargaining between an employer and a labor organization if such contract affects commerce as defined in this Act may be brought in any district court of the United States having jurisdiction of the parties.
“(b) Any labor organization whose activities affect commerce as defined in this Act shall be bound by the acts of its duly authorized agents acting within the scope of their authority from the said labor organization and may sue or be sued as an entity and in behalf of the employees whom it represents in the courts of the United States: Provided, That any money judgment against such labor organization shall be enforceable only against the organization as an entity and against its assets, and shall not be enforceable against any individual member or his assets.
“(e) For the purposes of this section district courts shall be deemed to have jurisdiction of a labor organization (1) in the district in which such organization maintains its principal office, or (2) in any district in which its duly authorized officers or agents are engaged in promoting or protecting the interests of employee members. The service of summons, subpena or other legal process upon such officer or agent shall constitute service upon the labor organization.
“(d) Any employee who participates in a strike or other stoppage of work in violation of an existing collective-bargaining agreement, if such strike or stoppage is not ratified or approved by the labor organization party to such agreement and having exclusive bargaining rights for such employee, shall lose his status as an employee of the em*496ployer party to such agreement for the purposes of sections 8, 9, and 10 of the National Labor Relations Act: Provided, That such loss of status for such employee shall cease if and when he is reemployed by such employer.
“The purpose of this amendment is simple: to make collective-bargaining contracts equally binding and enforceable on both parties to them. The courts have held that the purpose of the Wagner Act was—
“to compel employers to bargain collectively with their employees to the end that an employment contract, binding on both parties, should be made. (H. J. Heinz & Co., 311 U. S. 514 — 1941.)
“But neither the Wagner Act nor any other Federal statute makes labor unions legally responsible for carrying out their agreements.
“The laws of many States make it difficult to sue effectively and to recover a judgment against an unincorporated labor union. It is difficult to reach the funds of a union to satisfy a judgment against it. In some States it is necessary to serve all the members before an action can be maintained against the union. This is an almost impossible process (see testimony of Raymond S. Smethurst before committee, February 25, 1946). Despite these practical difficulties in the collection of a judgment against a union, the National Labor Relations Board has held it an unfair labor practice for an employer to insist that a union incorporate or post a bond to establish some sort of legal responsibility under a collective agreement.
“President Truman, in opening the management-labor conference in November 1945, took cognizance of this condition. He said very plainly that collec*497tive agreements should be mutually binding on both parties to the contract:
“We shall have to find methods not only of peaceful negotiation of labor contracts, but also of insuring industrial peace for the lifetime of such contracts. Contracts once made must be lived up to and should be changed only in the manner agreed upon by the parties. If we expect confidence in agreements made, there .must be responsibility and integrity on both sides in carrying them out.
“If unions can break agreements with relative impunity, then such agreements do not tend to stabilize industrial relations. The execution of an agreement does not by itself promote industrial peace. The main reason for an employer to sign a collective labor agreement is to assure uninterrupted operation during the term of the agreement. Without some effective method of assuring freedom from economic warfare for the term of the agreement, there is little reason why an employer would desire to enter into an agreement.
“Consequently, to encourage the making of agreements and to promote industrial peace through faithful performance by the parties, collective agreements dealing with interstate commerce should be enforceable in the Federal courts. Our amendment would provide for suits by unions as legal entities and against unions as legal entities in the Federal courts in disputes affecting commerce (as defined by sec. 2 (a)(1) of this act).
“The amendment specifically provides that only the assets of the union can be attached to satisfy a money judgment against it. The property of the individual members of the organization would become absolutely free from any liability under such a judgment. Thus the members of the union would *498secure all the advantages of limited liability without incorporation of the union.
“The proposed amendment relative to union liability specifically provides that a labor organization would be bound by the acts of its authorized agents only. Thus a labor organization would not be liable for damages arising as a result of an unauthorized strike carried on in violation of a contract. If a union or an officer thereof did not authorize the strike or participate in it, or support it, or subsequently approve it, no liability would be imposed on the union as a consequence of the work stoppage. To protect the employer against work stoppages in violation of an agreement but not approved by the union, employees who take part in such strikes would lose their status as employees under sections 8, 9, and 10 of the National Labor Relations Act. The employer could refuse to rehire them after the strike. Besides providing a remedy for the employer for irresponsible interruptions of production, such a provision would tend to strengthen sound union discipline.
“The initial obstacle in enforcing the terms of a collective agreement against a union which has breached its provisions is the difficulty of subjecting the union to process. The great majority of labor unions are unincorporated associations and at common law' voluntary associations are not suable as such (Wilson v. Airline Coal Company, 215 Iowa 855; Iron Molders’ Union v. Allis-Chalmers Company, C. C. A. 7, 166 F. 45). As a consequence the rule in all jurisdictions, in the absence of statute, is that unincorporated labor unions cannot be sued in their common name (Grant v. Carpenters’ District Council, 322 Pa. St. 62). Accordingly, the difficulty or impossibility of enforcing the terms of a collective *499agreement in a suit at law against a union arises from the fact that each individual member of the union must be named and made a party to the suit.
“Some States have enacted statutes which subject unincorporated associations to the jurisdiction of law courts. These statutes are by no. means uniform; some pertain to fraternal societies, welfare organizations, associations doing business, etc., and in some States the courts have excluded labor unions from their application.
“On the other hand, some States, including California and Montana, have construed statutes permitting common name suits against associations doing business to apply to labor unions (Armstrong v. Superior Court, 173 Cal. 341; Vance v. McGinley, 39 Mont. 46). Similarly, but more restrictive, in a considerable number of States the action is permitted against the union or representatives in proceedings in which the plaintiff could have maintained such an action against all the associates. Such States include Alabama, California, Connecticut, Delaware, Maryland, Montana, Nevada, New Jersey, New York, Rhode Island, South Carolina, and Vermont.
“In at least one jurisdiction, the District of Columbia, the liberal view is held that unincorporated labor unions may be sued as legal entities, even in the absence of statute (Busby v. Elec. Util. Emp. Union, U. S. Court of Appeals for the District of Columbia, No. 8548, January 22, 1945).
“In the Federal Courts, whether an unincorporated union can be sued depends upon the procedural rules of the State in which the action is brought (Busby v. Elec. Util. Empl. Union [323 U. S. 72], U. S. Supreme Court, 89 Law. Adv. Op. 108, December 4, 1944).
*500“The Norris-LaGuardia Act has insulated labor unions, in the field of injunctions, against liability for breach of contract. It has been held by a Federal court that strikes, picketing, or boycotting, when carried on in breach of a collective agreement, involve a 'labor dispute’ under the act so as to make the activity not enjoyable [sic] without a showing of the requirements which condition the issuance of an injunction under the act (Wilson & Co. v. [Birl,] 105 F. 2d 948, C. C. A. 3).
"A great number of States have enacted anti-injunction statutes modeled after the Norris-LaGuardia Act, and the courts of many of these jurisdictions have held that a strike in violation of a collective agreement is a ‘labor dispute’ and cannot be enjoined (The Nevins v. Kasmach, 279 N. Y. 323; Bulkin v. Sacks, 31 Pa. D & C 501).
“There are no Federal laws giving either an employer or even the Government itself any right of action against a union for any breach of contract. Thus there is no ‘substantive right’ to enforce, in order to make the union suable as such in Federal courts.
“Even where unions are suable, the union funds may not be reached for payment of damages and any judgments or decrees rendered against the association as an entity may be unenforceable. (See Aalco Laundry Co. v. Laundry Linen Union, 115 S. W. 2d 89 Mo. App.) However, only where statutes provide for recognition of the legal status of associations do association funds become subject to judgments (Deeney v. Hotel & Apt. Clerks’ Union, 134 P. 2d 328 (1943), California).
“Financial statutory liability of associations is provided for by some States, among which are Alabama, California, Colorado, Connecticut, Delaware, *501New Jersey, North Dakota, and South Carolina. Even in these States, however, whether labor unions are included within the definition of 'association’ is a matter of local judicial interpretation.
“It is apparent that until all jurisdictions, and particularly the Federal Government, authorize actions against labor unions as legal entities, there will not be the mutual responsibility necessary to vitalize collective-bargaining agreements. The Congress has protected the right of workers to organize. It has passed laws to encourage and promote collective bargaining.
“Statutory recognition of the collective agreement as a valid, binding and enforceable contract is a logical and necessary step. It will promote a higher degree of responsibility upon the parties to such agreements, and will thereby promote industrial peace.
“It has been argued that the result of making collective agreements enforceable against unions would be that they would no longer consent to the inclusion of a no-strike clause in a contract.
“This argument is not supported by the record in the few States which have enacted their own laws in an effort to secure some measure of union responsibility for breaches of contract. Four States— Minnesota, Colorado, Wisconsin, and California— have thus far enacted such laws and, so far as can be learned, no-strike clauses have been continued about as before.
“In any event, it is certainly a point to be bargained over and any union with the status of 'representative’ under the NLRA which has bargained in good faith with an employer should have no reluctance in including a no-strike clause if it intends to *502live up to the terms of the contract. The improvement that would result in the stability of industrial relations is, of course, obvious.” (Pp. 10-14.)
4. Senate debate;
a. Senator Taft:
“Mr. President, this amendment is the third and last of the amendments which attempt to strengthen the collective-bargaining process. I do not know of anything for which there has been greater demand than recognition that labor unions shall be responsible on their collective-bargaining contracts exactly as the employer is responsible. The United States Supreme Court has said that the purpose of the Wagner Act was:
“To compel employers to bargain collectively with their employees to the end that an employment contract, binding on both parties, should be made.
“I quote from President Truman’s address to the Management-Labor Conference in November 1945:
“We shall have to find methods not only of peaceful negotiation of labor contracts, but also of insuring industrial peace for the lifetime of such contracts.
“I quote still further from President Truman’s address:
“Contracts once made must be lived up to and should be changed only in the manner agreed upon by the parties. If we expect confidence in agreements made, there must be responsibility and integrity on both sides in carrying them out.
“A bill was introduced, as I recall, by the Senator from Virginia [Mr. Byrd] to require all labor unions to incorporate. We found that to be awkward, and we thought it unnecessary. All we provide in the amendment is that voluntary associations shall in *503effect be suable as if they were corporations, and suable in the Federal courts if the contract involves interstate commerce and therefore involves a Federal question. As a matter of fact, labor unions in theory are responsible for their contracts. At times they have been sued, including actions for tort. In the Danbury Hatters case it will be remembered a judgment was obtained, and because it was a voluntary association, the houses of all the various members were levied upon and taken in satisfaction of the judgment. We do not want to perpetuate such a condition. Therefore, we provide very simply that a labor union may be sued as if it were a corporation, and if it is sued, then the funds of the labor organization and its assets are responsible for the judgment, but the funds and the assets of the individual members are not liable on such a judgment. In other words, we think in subsection (a) and in subsection (b) we have fairly stated the proposition.
“Let me finish discussing subsection (c) first. It simply provides how labor unions may be sued, how they may be served, and provides the machinery by which the suit may be brought. The difficulty with respect to unincorporated associations is that under most State laws they are very difficult to sue. In theory, they are suable, but as a practical matter there are many States in which it is almost impossible to sue them. It is necessary to make practically every member of the labor organization a party to the suit. Various other kinds of restrictions and difficulties exist which, as a practical matter, in a large part of the United States makes it absolutely impossible to sue a labor union.” '(92 Cong. Rec. 5705.)
*504“What good is a collective-bargaining agreement if people are not bound by it? If there is a collective-bargaining agreement and the men are bound by it, they ought to carry it out. If the union wants to carry it out, and some of the men say, ‘We will not do it/ they ought to be liable. This provision applies only if the action of the individual is a violation of the collective-bargaining agreement.” {Id., at 5706.)
b. Senator Ball:
“The pending amendment very simply seeks to establish for unions the same responsibility for carrying out their contracts that now apply to employers. . . .
“Mr. President, it is the contention of some of the opponents of this amendment that unions are now suable in State courts. A lawyer on my staff looked up a number of recent decisions. Several of them show that in Kentucky, West Virginia, in Massachusetts, and in Illinois, all of which are important industrial States, unions cannot be sued as legal entities. . . .
“Mr. President, it seems to me that equal responsibility by both parties to a contract is a principle which the Senate should apply in the field of labor relations. I hope the amendment will be adopted.” (Id., at 5722.)
c. Senator Murray, opposing the measure, argued, among other things, that labor unions are peculiar in that they are unincorporated associations, that state rules regarding them are the same for all *505unincorporated associations, and that it would be unjust to subject the union to different rules in the federal courts. The following quotations, relied upon by those seeking to find federal substantive law in Section 301, must be viewed in the context of this procedural discussion:
“By their proposal, the minority members of the committee proposing this amendment would create a completely new Federal right in the United States courts. It would not create this new right as against all unincorporated associations, but it would set up a new and special court right against unions.
“To realize the full implication of this matter, it should be remembered that the courts of the United States, as distinguished from the courts of each of the several States, operate under a very longstanding set of laws defining their jurisdiction. It is not possible to bring each and any case into the United States courts. . . . The Federal courts were created solely for the purpose of handling special matters which are appropriately in the jurisdiction of a Federal agency. Thus, suits involving rights of a citizen under Federal statute may go to a Federal court. Suits involving citizens of more than one State may go to a Federal court under appropriate circumstances.
“What is the state of the law today with respect to the right to bring a suit in a Federal court for violation of a collective-bargaining agreement? The law in such a situation is identical with that affecting all individuals, corporations, or associations. Where there is diversity of citizenship— plaintiffs and defendants from different States— action may be brought in the Federal courts. Where rights under a Federal statute are involved, *506the matter may be brought to a Federal court. In short, where, under general law a matter appropriate for Federal jurisdiction is involved, suits under labor contracts, as under any other type of contract, may be brought in the Federal courts.
“The Senators making the present proposal are not satisfied with this, however. Their proposal would take labor agreements out of the category of normal State court operations, and would make them at all times and under all circumstances a matter for the Federal courts. The proposal would create a new and special Federal right to enforce in the Federal courts the terms in a labor agreement.” (Id., at 5708.)
“Continuing my discussion of the amendment, I wish to say that the first issue is not whether a collective-bargaining agreement may be enforced in court. Collective-bargaining agreements are as enforceable in the courts as any other kind of agreement under the law today. The first question is whether collective-bargaining agreements, unlike any other agreements, are to be thrown into the Federal courts and made the subject of Federal court jurisdiction.” (Id., at 5720.)
d. Senator Magnuson, opposing the amendment before it was actually introduced, went into detailed consideration of the amendment, which he described as one to “create a right of action, under Federal statute, for breach of a collective-bargaining agreement.” He asserted that such agreements were already fully binding legally on both parties, and that the difficulty was in the union’s status as an unincorporated association. He defended the necessity for the restrictive rules regarding suits against such associations, and emphasized the modification of *507the rule in many states designed to facilitate suits against unions. Then:
“The minority views of the Senate Labor Committee in urging the adoption of the amendment, correctly assert that the Federal courts must follow the laws of the States in suits on collective-bargaining agreements when a Federal statute is not involved. The minority views however, give an incorrect picture of the laws of the various States on the question. At the present time, fully three-fourths of the States permit suits to be brought against unincorporated associations in their own names. In other words, at least three-fourths of the States allow a suit to be brought against any employee or any group of employees for the violation of a collective-bargaining agreement.
“The comparative freedom of courts of equity also make [sfc] it possible for them to limit recoveries to funds or property belonging to the associations as a condition for permitting this type of suit. Senators, in view of this progress made by the States, I see no reason why it is necessary for the Federal Government to invade the realm of the States to such an extent as to furnish them laws governing suits for breaches of purely private contracts. The law governing private contracts has traditionally been a matter for State control, and we should not lightly violate this separation of functions under the guise of controlling interstate commerce.
“Mr. President, the minority views picture a dark future for a party who wishes to enforce an agreement with a labor union. Actually the picture given is quite misleading. For instance, it says that *508an employer or even the Government has no Federal right of action to enforce a collective bargaining agreement.
“Of course, the amendment of the Senator from Minnesota would allow a Federal right of action to enforce a collective-bargaining agreement. All of us who are lawyers know that a party who enters into an ordinary private contract has practically no Federal right of action to have the contract enforced.
“. . . Under the amendment of the Senator from Minnesota a contract would be enforceable only in Federal courts, and would, therefore, violate a longtime cardinal principle of law, namely, that all contracts are enforceable, if at all, in State courts.
“Mr. President, there is another point regarding the pending amendment which I should like to mention. The amendment under discussion is designed to make it easier for employers to bring suit against labor unions. Do the Members of the Senate realize that it is almost impossible for a labor union to sue an employer for breach of contract? Collective-bargaining agreements are generally construed either as contracts between the employer and the employees or contracts for the benefit of the employees. In either case injured employees must usually sue for themselves. A union may not bring suit because it has no interest in the matter. Furthermore, even though its disability to sue as an unincorporated association has now largely been removed, it still has the same difficulties bringing suit as an employer does in bringing it into court as a defendant. If the Senate is going to confer special *509privileges on one side, it probably should also adopt an amendment which would confer the same privileges on the other side.
“Mr. BALL. . . . The Senator is complaining that unions have difficulty in suing employers for violations of contract. This amendment would cure that situation.
“Mr. MAGNUSON. I do not so understand it. Perhaps I have not read the amendment too carefully, or perhaps the language has been changed.
“Mr. BALL. The language of the amendment is ‘may sue or be sued.’ ” (Id., at 5412-5415.)
e. Senator Magnuson’s belief that the section was intended to exclude State court jurisdiction was disposed of later by Senator Ferguson, answering Senator Murray’s similar assumption. (Id., at 5708.) These incorrect assumptions by Senator Magnuson do much to explain his belief that a federal “right of action” was granted by § 10. Moreover, his discourse occurred prior to Senator Taft’s explanation of the purpose of the amendment.
5. Senator Taft’s amendment was incorporated in the bill by the Senate without substantial alteration. 92 Cong. Rec. 5723. See I., D., infra, p. 511.
C. House debates:
1. The House accepted the Senate version of § 10 without requesting a conference.
2. Representative Case:
“All this section on suability does is to carry out the same purpose we had in the House bill, when we provided for making contracts actually binding *510upon both parties to it. It has been found that while a few States permit suing on a labor contract, many States do not. Unless you have some such provision as this in Federal law, collective-bargaining contracts will not be good, in the words of the President, 'for the lifetime of such contracts.’
“So the Senate very carefully and properly drafted this provision in the way they did, to insure that 'contracts,’ again in the words of President Truman, 'once made must be lived up to’ and 'changed only in the manner agreed upon by the parties.’
“Individual members of a union are not made liable for any money judgment, I might point out, but only the union as an entity. ...” (92 Cong. Rec. 5930-5931.)
3. Representative Slaughter:
“The second point in the bill provides for mutuality of contracts. Who is there in this body or in any labor union or among any group of right-minded men and women who would say that both parties to a contract are not mutually liable. . . .
“An employer is liable for his contracts and should be, and, by the same token, so should the employee.” {Id., at 5942.)
4. Representative Springer:
“. . . It does, however, contain the provision that after collective bargaining and the meeting of the minds upon a contract, agreeable to both parties, that for the duration of that contract, so agreed upon, both parties are bound by the terms and provisions of that contract.
“Of course, that is merely the law under which every American is guided. The sanctity of contracts must remain inviolate, and all parties to a *511contract fully agreed upon, . . . must be bound by the terms and provisions contained therein. ... it would be an assurance that labor would carry out its contractual obligations under the provisions of the contracts made and entered into. . . .” (Id., at 5944.)
5. Representative Robsion:
“. . . It also provides for suits by labor organizations for damages done to them by management for violation of contract and the right of action is given to the employer against the labor union for damages sustained by the breach of a contract between the employer and the union. . . . When a contract is once entered into the aggrieved party should have the right of action against the party at fault. . . (Id., at 5939.)
D. The bill, as passed by both Houses:
“Sec. 10. (a) Suits for violation of a contract concluded as the result of collective bargaining between an employer and a labor organization if such contract affects commerce as defined in this Act may be brought in any district court of the United States having jurisdiction of the parties.
“(b) Any labor organization whose activities affect commerce as defined in this Act shall be bound by the acts of its duly authorized agents acting within the scope of their authority from the said labor organization and may sue or be sued as an entity and in behalf of the employees whom it represents in the courts of the United States: Provided, That any money judgment against such labor organization shall be enforceable only against the organization as an entity and against its assets, and shall not be enforceable against any individual member or his assets.
*512“(c) For the purposes of this section district courts shall be deemed to have jurisdiction of a labor organization (1) in the district in which such organization maintains its principal office, or (2) in any district in which its duly authorized officers or agents are engaged in promoting or protecting the interests of employee members. The service of summons, subpena, or other legal process upon such officer or agent shall constitute service upon the labor organization.
“(d) Any employee who participates in a strike or other interference with the performance of an existing collective bargaining agreement, in violation of such agreement, if such strike or interference is not ratified or approved by the labor organization party to such agreement and having exclusive bargaining rights for such employee, shall lose his status as an employee of the employer party to such agreement for the purposes of sections 8, 9, and 10 of the National Labor Relations Act: Provided, That such loss of status for such employee shall cease if and when he is reemployed by such employer.”
E. Veto Message (H. R. Doc. No. 651, 79th Cong., 2d Sess.):
“Section 10:
“I am in accord with the principle that it is fair and right to hold a labor union responsible for a violation of its contract. However, this legislation goes much further than that.. This section, taken in conjunction with the next section, largely repeals the Norris-LaGuardia Act and changes a long-established congressional policy.
“I am sure that, without repealing the Norris-LaGuardia Act, ... a sound and effective means of enforcing labor’s responsibility can be found.”
*513II. The Taft-Hartley Act.
A. Legislative history in the House:
1. Hearings before Committee on Education and Labor on H. R. 8, 725, 880, 1095, and 1096, 80th Cong., 1st Sess.:
a. Among the bills under consideration, only H. R. 725 contained a section concerning federal jurisdiction touching breach of contract. It provided:
“equal responsibility and liability
“Sec. 305. (a) Suits for violations of contracts between an employer and a labor organization if such contracts affect commerce as defined in this Act may be brought by either party in any district court of the United States having jurisdiction of the parties.
“(b) Any labor organization whose activities affect commerce as defined in this Act shall be bound by the acts of its duly authorized agents acting within the scope of their authority from the said labor organization, and may sue or be sued as an entity and in behalf of the employees whom it represents in the courts of the United States: Provided, That any money judgment against such labor organization shall be enforceable only against the organization as an entity and against its assets, and shall not be enforceable against any individual member or his assets.
“(c) For the purposes of this section, district courts shall be deemed to have jurisdiction of a labor organization (1) in the district in which such organization maintains its principal office, or (2) in any district in which its duly authorized officers *514or agents are engaged in promoting or protecting the interests of employee members. The service of summons, subpena, or other legal process upon such officer or agent shall constitute service upon the labor organization.”
b. Discussion of the problem of contract responsibility was frequent, but almost exclusively in general terms of the existence of a problem and the desirability of having collective agreements enforceable against the union as well as the employer. See pp. 4, 34-36, 90-91, 125, 135, 227, 229, 406, 533, 547, 558-559, 569-570, 582, 590-591, 593, 673, 1007-1008, 1074, 1088, 1218, 1804, 1891, 2292, 2345, 2368, 2530, 2532, 2631, 2695.
c. The only considered analysis of the problem, and the remedy proposed, occurred in the testimony of Secretary of Labor Schwellenbach:
“suits by and against labor organizations
“H. R. 267, section 305 of H. R. 725, section 4 of H. R. 1430, and section 2 of H. J. Res. 43, refer to suits by and against labor organizations.
“Few subjects are so widely discussed and so little understood as this one. I agree that labor unions should be subject to suit. The general idea seems to be that labor unions are not subject to suit because they are labor unions. Such a concept has no basis in law.
“In some States labor unions are not suable in their common names because they are unincorporated associations.
“As a matter of fact, there are only 13 States where unincorporated associations cannot be sued in their common name in an action at law for breach of contract or tortious conduct. . . .
*515“Since the adoption of the Federal Rules of Civil Procedure, there are 35 States where they can sue or be sued in the Federal courts. Rule 17 (b) of those rules provides in part [reading]:
"... capacity to sue or be sued shall be determined by the law of the State in which the district court is held; except that a partnership or other unincorporated association, which has no such capacity by the law of such State, may sue or be sued in its common name for the purpose of enforcing for or against it a substantive right existing under the Constitution or laws of the United States.
“Since the field of necessary legislative action is so narrow, I see no reason why the gates of the Federal courts should be opened so wide as to invite litigation, as would be done by the bills listed above.
“I have three suggestions to make concerning these bills.
“Second, I do not see why it is necessary in this field to abandon the diversity of citizenship requirement. In fact, I doubt that it can be abandoned constitutionally. The Constitution, as you know, limits suits in the Federal courts to cases arising under the Constitution and the laws of the United States or involving diversity of citizenship.
“I grappled with the question of what the meaning of ‘arising under the laws of the United States’ was a good many times and I make no categorical statement as to whether or not under this proposed legislation the courts would hold that suits so started would arise under the laws of the United States.
“However, the general concept always has been in private litigation that a necessary prerequisite to Federal jurisdiction is diversity of citizenship.” (Pp. 3016-3017.)
*5162. The bill, as reported from committee (H. R. 3020):
“equal responsibility and liability
“Sec. 302. (a) Any action for or proceeding involving a violation of an agreement between an employer and a labor organization or other representative of employees may be brought by either party in any district court of the United States having jurisdiction of the parties, without regard to the amount in controversy, if such agreement affects commerce, or the court otherwise has jurisdiction of the cause.
“(b) Any labor organization whose activities affect commerce shall be bound by the acts of its agents, and may sue or be sued as an entity and in behalf of the employees whom it represents in the courts of the United States. Any money judgment against a labor organization in a district court of the United States shall be enforceable only against the organization as an entity and against its assets, and shall not be enforceable against any individual member or his assets.
“(c) For the purposes of actions and proceedings by or against labor organizations in the district courts of the United States, district courts shall be deemed to have jurisdiction of a labor organization (1) in the district in which such organization maintains its principal office, or (2) in any district in which its duly authorized officers or agents are engaged in representing or acting for employee members.
“(d) The service of summons, subpena, or other legal process of any court of the United States upon an officer or agent of a labor organization, in his capacity as such, shall constitute service upon the labor organization.
*517“(e) In actions and proceedings involving violations of agreements between an employer and a labor organization or other representative of employees, the provisions of the Act of March 23, 1932, entitled 'An Act to amend the Judicial Code and to define and limit the jurisdiction of courts sitting in equity and for other purposes,’ shall not have any application in respect of either party.”
3. House Report (No. 245, 80th Cong., 1st Sess.):
a. Majority:
“It makes labor organizations equally responsible with employers for contract violations and provides for suit by either against the other in the United States district courts.” (P. 6.)
“Section SOB deals in improved form with another subject which was included in last year’s Case bill. It provides that actions and proceedings involving violations of contracts between employers and labor organizations may be brought by either party in any district court of the United States ....
“When labor organizations make contracts with employers, such organizations should be subject to the same judicial remedies and processes in respect of proceedings involving violations of such contracts as those applicable to all other citizens. Labor organizations cannot justifiably ask to be treated as responsible contracting parties unless they are willing to assume the responsibility of such contracts to the same extent as the other party must assume his. Public opinion polls in evidence before the committee show that nearly 75 percent of the union members themselves concur in this view. For this reason, not only does the section, as heretofore *518pointed out, make the labor organization equally suable, but it also makes the Norris-LaGuardia Act inapplicable .... Among other things, this change makes applicable in such cases as these the rules of evidence that apply in suits involving all other citizens.” (Pp. 45-46.)
b. Minority:
“Section 302 of title III has the dual purpose first of giving the Federal courts jurisdiction, without regard to the amount in controversy, to entertain actions involving violations of collective bargaining agreements affecting commerce or where the court otherwise has jurisdiction of the cause; and, second, of providing for suit against labor organizations whose activities affect commerce, with judgment enforceable only against the union assets. In any such suits the union would be bound by the acts of its agents and the courts would have the power to grant injunctive relief regardless of the provisions of the Norris-LaGuardia Act.
“The question of amenability of unions to suit has been the subject of much misunderstanding. Unions have never been exempt from suit because they are labor unions. It has only been difficult to reach union assets because unions are unincorporated associations. And even here, these difficulties have been removed in the great majority of States. Actually, there are only 13 States where union funds cannot be easily reached under laws in effect permitting satisfaction of judgments from the central funds of the union. ... Of the remaining 35 States, there are 10 which by statute permit the union assets to be reached by representative suits in any type of action and there are 25 which permit suits against unions in the common name of the *519union, in some cases with liability attaching not only to the union funds, but also to the assets of every individual member of the union.
“This bill would seek to open the Federal courts generally to suits by and against labor organizations. Since the adoption of the Federal Rules of Civil Procedure, however, the Federal courts have already been authorized to entertain suits by and against labor organizations in the 35 States which already permit effective recovery against union funds. Rule 17 (b) of those rules provides in part as follows:
“. . . The capacity of an individual, other than one acting in a representative [sic], to sue or be sued shall be determined by the law of his domicile. ... In all other cases capacity to sue or be sued shall be determined by the law of the State in which the district court is held; except that a partnership or other unincorporated association, which has no such capacity by the law of such State, may sue or be sued in its common name for the purpose of enforcing for or against it a substantive right existing under the Constitution or laws of the United States.
“It is concluded, therefore, that there now exists only a very narrow field for necessary Federal legislative action. There is perceived very little reason why the Federal courts should now be opened to so wide a degree, inviting litigation, when rules presently in existence effectively permit suit and may, in the sound discretion of the United States Supreme Court, be broadened even further to permit suit regardless of State procedural laws and without the necessity of further legislation.
“The question of conferring upon Federal courts broad power to entertain suits for violation of union agreements regardless of the amount involved and apparently in complete disregard of the constitutional requirement of diversity of citizenship is *520fraught with grave issues of policy and legality. It would appear particularly unwise to abandon in this field the present requirement of the $3,000 amount in controversy as a prerequisite to Federal jurisdiction. It is feared that the result would be to involve the Federal courts, already overburdened, with a great mass of petty litigation over amounts less than $3,000, easily capable of being adjudicated effectively by the more numerous State courts. This type of action would undoubtedly invite the return of conditions in the Federal Courts during prohibition days, when they bogged down in litigation ordinarily handled by the average police court.
“As to legality, the bill would apparently give the Federal courts jurisdiction of disputes over union agreements affecting commerce regardless of diversity of citizenship of the parties. The Constitution limits suits in the Federal courts to cases arising under the Constitution and laws of the United States or involving diversity of citizenship (Constitution, art. 3, sec. 2). The bill apparently attempts to found jurisdiction upon the Constitution and laws of the United States by the use of the words ‘if such agreement affects commerce.’ There would be involved here, however, no substantive right under the laws of the United States or under the Constitution. Actually substantive legal questions as to a contract dispute would be decided in accordance with applicable State law. The United States Supreme Court has held that the fact that the circumstances involve engaging in interstate commerce will not permit the Federal courts to assume jurisdiction where there is no diversity of citizenship (In Re Metropolitan Railway Receivership, 208 U. S. 90, 28 S. Ct. 219, 52 L. Ed. 403). *521It is therefore concluded that this aspect of the bill constitutes an approach which is of doubtful legality and certainly is both hasty and unwise.
“It is noted that the bill makes an effort to secure union responsibility for the acts of its agents. Very general language is used. It is submitted, however, that, instead, care should be used in determining what are acts of duly authorized agents acting within the scope of their authority. . . .” (Pp. 108-110.)
4. House debates:
a. Representative Hartley:
“It makes labor organizations equally responsible with employers for contract violations and provides for suit by either against the other in the United States district courts.” (93 Cong. Rec. 3424.)
b. Both Mr. Hartley and Mr. Case agreed to the following statement by Representative Barden:
“It is my understanding that section 302, the section dealing with equal responsibility under collective bargaining contracts in strike actions and proceedings in district courts contemplates not only the ordinary lawsuits for damages but also such other remedial proceedings, both legal and equitable, as might be appropriate in the circumstances; in other words, proceedings could, for example, be brought by the employers, the labor organizations, or interested individual employees under the Declaratory Judgments Act in order to secure declarations from the Court of legal rights under the contract.” (Id., at 3656.)
c. No other member of the committee made a statement with regard to the section. Nor did any other *522member cast any light upon the section. Only casual references to it appear. (Pp. 3529, 3531, 3666.)
5. The bill passed the House in the same form as introduced.
B. Legislative history in the Senate:
1. Hearings before Committee on Labor and Public Welfare on S. 55 and S. J. Res. 22, 80th Cong., 1st Sess.:
a. S. 55, under consideration, was introduced by Senators Ball, Taft and Smith, and contained as Section 203:
“SUITS BY AND AGAINST LABOR ORGANIZATIONS
"Sec. 203. (a) Suits for violation of contracts concluded as the result of collective bargaining between an employer and a labor organization representing employees in an industry affecting commerce as defined in this Act may be brought in any district court of the United States having jurisdiction of the parties.
“(b) Any labor organization which represents employees in an industry affecting commerce as defined in this Act shall be bound by the acts of its duly authorized agents acting within the scope of their authority from the said labor organization and may sue or be sued in its common name in the courts of the United States: Provided, That any money judgment against such labor organization shall be enforceable only against the organization as an entity and against its assets, and shall not *523be enforceable against any individual member or his assets.
“(c) For the purposes of this section district courts shall be deemed to have jurisdiction of a labor organization (1) in the district in which such organization maintains its principal office, or (2) in any district in which its duly authorized officers or agents are engaged in promoting or protecting the interests of employee members. The service of summons, subpena, or other legal process upon such officer or agent shall constitute service upon the labor organization.
“(d) Any employee who participates in a strike or other interference with the performance of an existing collective-bargaining agreement, in violation of such agreement, if such strike or interference is not ratified or approved by the labor organization party to such agreement and having exclusive bargaining rights for such employee, shall lose his status as an employee of the employer party to such agreement for the purposes of sections 8, 9, and 10 of the National Labor Relations Act: Provided, That such loss of status for such employee shall cease if and when he is reemployed by such employer.”
b. Again, there was considerable general discussion regarding the necessity for making unions responsible for their agreements. (Pp. 389, 635, 780, 965, 1227, 1321, 1422,1493, 1617, 1656, 1817, 2019, 2349, 2371.)
c. The unions, in testimony and filed statements, unanimously opposed the section. One of the points constantly made was that the belief that state law did not regard them as responsible on their contracts was erroneous. (Pp. 1042, 1154, 1391, 1534, *5241547, 2295.) The procedural nature of the problem was, however, seldom made explicit. (Pp. 689, 1798, 2011.)
d. Again the most significant testimony occurred when Secretary of Labor Schwellenbach appeared as a witness:
“Secretary SCHWELLENBACH. . . . Suits by and against labor organizations: This is a subject upon which there is much discussion and about which there is very little widespread information. The general concept is that labor unions are exempt from suits because they are labor unions. There is no legal basis for this conclusion. They are exempt from suits because they are unincorporated associations. Actually there are only 13 States in the Union where unincorporated associations are not subject to suits ....
“Since the adoption of the Federal Rules of Civil Procedure, there are 35 States where they can sue or be sued, in the Federal courts.
“Since the field of necessary legislative action is so narrow, I see no reason why the gates of the Federal courts should be opened so wide as to invite litigation, as is done by this proposed section. Speaking as a lawyer and former member of the Federal judiciary, I have an objection to the abandonment in this field of the requirement of the $3,000 amount in controversy as a prerequisite to Federal jurisdiction. This is a right which has been jealously guarded by the Congress and by the Federal courts. To have them cluttered up with a great mass of petty litigation involving amounts less than $3,000 would bring them back to the position which *525they occupied during prohibition days when they became just a little bit above the level of the average police court insofar as criminal work was concerned.
“I do not see why it is necessary in this field to abandon the diversity of citizenship requirement. In fact I doubt that it can be abandoned constitutionally. The Constitution, as you know, limits suits in the Federal courts to cases arising under the Constitution and the laws of the United States or involving diversity of citizenship.
“I grappled with the question of what the meaning of ‘arising under the laws of the United States’ was a good many times and I make no categorical statement as to whether or not under this proposal [sic] legislation the courts would hold that suits so started would arise under the laws of the United States. However, the general concept always has been in private litigation that a necessary prerequisite to Federal jurisdiction is diversity of citizenship. In addition to that, care should be used in determining what are acts of duly authorized agents operating within the scope of their authority. To that extent a distinction must be made between labor unions and other organizations. The question was fully discussed, studied, and argued by the Congress at the time of the passage of the Norris-LaGuardia Act and the language there used limited the liability of the organization to those ‘unlawful acts of individual officers, members or agents,’ where there is ‘clear proof of actual participation in or actual authorization of such acts or of ratification of such acts after actual knowledge thereof.’ With few exceptions I have found that the officers of international unions were just as anxious to pre*526vent the breaking of contracts as were the employers. I found that the officers of local unions by and large were much more anxious to prevent breaking of contracts than some small groups within the union. I respectfully suggest that the language of the Norris-LaGuardia Act should be inserted in the provision of this section.
“The CHAIRMAN [Senator Taft]. Mr. Secretary, of course, the basis for the jurisdiction is the Federal law — in other words, we are saying that all matters of collective-bargaining contracts shall be made in certain ways; that both parties shall be compelled to negotiate them, and they furnish the solution for the difficulty, which is an interstate commerce difficulty. I don’t quite see why suits regarding such collective-bargaining contracts, when made, are not properly the subject of Federal law arising under the laws of the United States, therefore subject properly to the jurisdiction of the Federal courts. I don’t understand how we can cover the whole subject, as we do, in Federal laws, and then say, when you come down to suing about it, that the Federal court has no jurisdiction. I don’t understand that.
“Secretary SCHWELLENBACH. I am not contending that the Federal court should not have jurisdiction. My two objections are that you should not clutter up the Federal courts with small suits, and—
“The CHAIRMAN. I should not think there would be many suits against unions for violating collective-bargaining contracts. I think that would be only a club in a closet. It would be an awkward suit. Many unions would not have any funds to collect, and I should think that any suit brought *527would certainly involve more than $3,000. It doesn’t seem to me that this would bring any great deluge of litigation upon the Federal courts.
“Secretary SCHWELLENBACH. I am testifying as a former Federal judge with a desire to protect the courts from a large volume of small matters.
“Senator ELLENDER. What limitation would you make?
“Secretary SCHWELLENBACH. You should have the same requirements for jurisdiction in reference to these suits, $3,000 the amount in controversy, and diversity of citizenship. They have got the right to go into the State courts, you know, in 35 of the 48 States.
“Senator BALL. Aren’t there some pretty important industrial States among those 13, though, where they cannot go into the State courts, such as Massachusetts and Virginia, Rhode Island?
“Senator DONNELL. Don’t leave out Illinois and Missouri. [Laughter.]
“Secretary SCHWELLENBACH. I am not going to get into that one.
“Senator PEPPER. Mr. Secretary, in any of these 13 States that you have mentioned, where an unincorporated association is not suable, if those States were to provide that they are suable, under the Federal rules they would be suable in the Federal courts. So in those cases the matter would be up to the State to determine whether the Federal courts should have jurisdiction or not, and whether they would be suable in the State courts or not.
“Secretary SCHWELLENBACH. I am not objecting to the provision, except I don’t like the idea.
“Senator PEPPER. That is the fact, isn’t it?
“Secretary SCHWELLENBACH. Yes.
*528“Senator PEPPER. Now, in the second place I get the intimation from your statement that you made the decision [sic], which I was not quite sure the chairman recognized or agreed to, namely, that there was a difference between intrusting a right that exists under the Federal law or Federal Constitution, for which there could be redress in the Federal court, and the attempt of Congress merely to provide a Federal forum, Federal procedure, for the determination of the substantive rights which might be enforced by State law? Isn’t that a distinction that you meant to suggest?
“Secretary SCHWELLENBACH. When I was on the bench I suppose I tried half a dozen or 10 cases involving the question of whether or not there was jurisdiction, because they arose under the Federal statute, and they are tough, very tough, very hard to distinguish. And I am not making any categorical statement.
“Senator PEPPER. I mean to suggest this distinction: If Congress should provide a forum—
“Secretary SCHWELLENBACH. That is what this proposes to do; provide a Federal forum for suits against labor.
“Senator PEPPER. For violation of substantive rights. If Congress were to lay down rules of damages in cases within congressional jurisdiction — that is, involving interstate commerce — if Congress were to lay down the obligations of the parties and prescribe the rules and measure of damages, and so forth, for the violation of those obligations, then a suit for the enforcement of the penalty provided, or for the redress allowed, might properly be brought in the Federal “courts, but what seems to be the intention here is to transfer to the Federal courts *529suits for breach of contract, the contracts being entered into under local law, and redress in all but 13. States being available now under local law.” (Pp. 56-58.)
2. The bill as reported:
“SUITS BY AND AGAINST LABOR ORGANIZATIONS
“Sec. 301. (a) Suits for violation of contracts concluded as the result of collective bargaining between an employer and a labor organization representing employees in an industry affecting commerce as defined in this Act may be brought in any district court of the United States having jurisdiction of the parties, without respect to the amount in controversy or without regard to the citizenship of the parties.
“(b) Any labor organization which represents employees in an industry affecting commerce as defined in this Act may sue or be sued in its common name in the courts of the United States: Provided, That any money judgment against such labor organization shall be enforceable only against the organization as an entity and against its assets, and shall not be enforceable against any individual member or his assets.
“(c) For the purposes of this section district courts shall be deemed to have jurisdiction of a labor organization (1) in the district in which such organization maintains its principal office, or (2) in any district in which its duly authorized officers or agents are engaged in promoting or protecting the interests of employee members. The service of legal process upon such officer or agent shall constitute service upon the labor organization, and make such organization a party to the suit.”
*5303. Senate Report (No. 105, 80th Cong., 1st Sess.):
a. Majority:
“ENFORCEMENT OF CONTRACT RESPONSIBILITIES
“The committee bill makes collective-bargaining contracts equally binding and enforceable on both parties. In the judgment of the committee, breaches of collective agreement have become so numerous that it is not sufficient to allow the parties to invoke the processes of the National Labor Relations Board when such breaches occur (as the bill proposes to do in title I). We feel that the aggrieved party should also have a right of action in the Federal courts. Such a policy is completely in accord with the purpose of the Wagner Act which the Supreme Court declared was 'to compel employers to bargain collectively with their employees to the end that an employment contract, binding on both parties, should be made’ (H. J. Heinz & Co., 311 U. S. 514).
“The laws of many States make it difficult to sue effectively and to recover a judgment against an unincorporated labor union. It is difficult to reach the funds of a union to satisfy a judgment against it. In some States it is necessary to serve all the members before an action can be maintained against the union. This is an almost impossible process. Despite these practical difficulties in the collection of a judgment against a union, the National Labor Relations Board has held it an unfair labor practice for an employer to insist that a union incorporate or post a bond to establish some sort of legal responsibility under a collective agreement.
“President Truman, in opening the management-labor conference in November 1945, took cognizance *531of this condition. He said very plainly that collective agreements should be mutually binding on both parties to the contract:
“We shall have to find methods not only of peaceful negotiations of labor contracts, but also of insuring industrial peace for the lifetime of such contracts. Contracts once made must be lived up to and should be changed only in the manner agreed upon by the parties. If we expect confidence in agreements made, there must be responsibility and integrity on both sides in carrying them out.
“If unions can break agreements with relative impunity, then such agreements do not tend to stabilize industrial relations. The execution of an agreement does not by itself promote industrial peace. The chief advantage which an employer can reasonably expect from a collective labor agreement is assurance of uninterrupted operation during the term of the agreement. Without some effective method of assuring freedom from economic warfare for the term of the agreement, there is little reason why an employer would desire to sign such a contract.
“Consequently, to encourage the making of agreements and to promote industrial peace through faithful performance by the parties, collective agreements affecting interstate commerce should be enforceable in the Federal courts. Our amendment would provide for suits by unions as legal entities and against unions as legal entities in the Federal courts in disputes affecting commerce.
“The amendment specifically provides that only the assets of the union can be attached to satisfy a money judgment against it; the property of the individual members of the organization would not be subject to any liability under such a judgment. Thus the members of the union would secure all *532the advantages of limited liability without incorporation of the union.
“The initial obstacle in enforcing the terms of a collective agreement against a union which has breached its provisions is the difficulty of subjecting the union to process. The great majority of labor unions are unincorporated associations. At common law voluntary associations are not suable as such (Wilson v. Airline Coal Company, 215 Iowa 855; Iron Molders’ Union v. Allis-Chalmers Company, C. C. A. 7, 166 F. 45). As a consequence the rule in most jurisdictions, in the absence of statute, is that unincorporated labor unions cannot be sued in their common name (Grant v. Carpenters’ District Council, 322 Pa. St. 62). Accordingly, the difficulty or impossibility of enforcing the terms of a collective agreement in a suit at law against a union arises from the fact that each individual member of the union must be named and made a party to the suit.
“Some States have enacted statutes which subject unincorporated associations to the jurisdiction of law courts. These statutes are by no means uniform; some pertain to fraternal societies, welfare organizations, associations doing business, etc., and in some States the courts have excluded labor unions from their application.
“On the other hand, some States, including California and Montana, have construed statutes permitting common name suits against associations doing business to apply to labor unions (Armstrong v. Superior Court, 173 Calif. 341; Vance v. McGinley, 39 Mont. 46). Similarly, but more restrictive, in a considerable number of States the action is permitted against the union or representatives [sic] in proceedings in which the plaintiff could have *533maintained such an action against all the associates. . . .
“In at least one jurisdiction, the District of Columbia, the liberal view is held that unincorporated labor unions may be sued as legal entities, even in the absence of statute (Busby v. Elec. Util. Emp. Union, U. S. Court of Appeals for the District of Columbia, No. 8548, Jan. 22,1945).
“In the Federal courts, whether an unincorporated union can be sued depends upon the procedural rules of the State in which the action is brought (Busby v. Elec. Util. Empl. Union [323 U. S. 72], U. S. Supreme Court, 89 Law. Adv. Op. 108, Dec. 4, 1944).
“The Norris-LaGuardia Act has insulated labor unions, in the field of injunctions, against liability for breach of contract. It has been held by a Federal court that strikes, picketing, or boycotting, when carried on in breach of a collective agreement, involve a 'labor dispute’ under the act so as to make the activity not enjoyable [sic] without a showing of the requirements which condition the issuance of an injunction under the act (Wilson & Co. v. [Birl,] 105 F. (2d) 948, C. C. A. 3).
“A great number of States have enacted anti-injunction statutes modeled after the Norris-La-Guardia Act, and the courts of many of these jurisdictions have held that a strike in violation of a collective agreement is a 'labor dispute’ and cannot be enjoined (Nevins v. Kasmach, 279 N. Y. 323; Bulkin v. Sacks, 31 Pa., D and C 501).
“There are no Federal laws giving either an employer or even the Government itself any right of action against a union for any breach of contract. Thus there is no 'substantive right’ to enforce, in order to make the union suable as such in Federal courts.
*534“Even where unions are suable, the union funds may not be reached for payment of damages and any judgments or decrees rendered against the association as an entity may be unenforceable. (See Aalco Laundry Co. v. Laundry Linen Union, 115 S. W. 2d 89 Mo. App.) However, only where statutes provide for recognition of the legal status of associations do association funds become subject to judgments (Deeney v. Hotel & Apt. Clerks’ Union, 134 P. 2d 328 (1943), California).
“Financial statutory liability of associations is provided for by some States, among which are Alabama, California, Colorado, Connecticut, Delaware, New Jersey, North Dakota, and South Carolina. Even in these States, however, whether labor unions are included within the definition of 'association’ is a matter of local judicial interpretation.
“It is apparent that until all jurisdictions, and particularly the Federal Government, authorize actions against labor unions as legal entities, there will not be the mutual responsibility necessary to vitalize collective-bargaining agreements. The Congress has protected the right of workers to organize. It has passed laws to encourage and promote collective bargaining.
“Statutory recognition of the collective agreement as a valid, binding, and enforceable contract is a logical and necessary step. It will promote a higher degree of responsibility upon the parties to such agreements, and will thereby promote industrial peace.
“It has been argued that the result of making collective agreements enforceable against unions would be that they would no longer consent to the inclusion of a no-strike clause in a contract.
*535“This argument is not supported by the record in the few States which have enacted their own laws in an effort to secure some measure of union responsibility for breaches of contract. Four States— Minnesota, Colorado, Wisconsin, and California— have thus far enacted such laws and, so far as can be learned, no-strike clauses have been continued about as before.
“In any event, it is certainly a point to be bargained over and any union with the status of 'representative’ under the NLRA which has bargained in good faith with an employer should have no reluctance in including a no-strike clause if it intends to live up to the terms of the contract. The improvement that would result in the stability of industrial relations is, of course, obvious.” (Pp. 15-18.)
“Section 301 is the only section contained in [Title III]. It relates to suits by and against labor organizations for breach of collective bargaining agreements and should be read in connection with the provisions of section 8 of title I also dealing with breach of contracts. The legal effect of this section has been described at some length in the main body of the report, supra.” (P. 30.)
b. Minority:
“Finally, sections 8 (a) (6) and 8 (b) (5) together with section 301 would give rise to a conflict of jurisdiction between the National Labor Relations Board and the United States district courts. This latter section permits suits in the United States district courts for violations of collective-bargaining agreements. Parties to such agreements thus have the choice of bringing their action before the Board or the United States district courts. Obviously, *536the necessity for uniform decisions in such matters and the avoidance of conflicting decisional rules by judicial bodies make this legislative scheme wholly undesirable.
“(1) Suits for violation of collective-bargaining agreements
“The Federal courts have always had jurisdiction to entertain suits for breach of collective-bargaining contracts and have awarded money damages where the amount in controversy fulfills the present $3,000 requirement and diversity of citizenship exists. Nederlandsche Amerikaanische Stoomvart Maatschappij v. Stevedores and Longshoremen’s Benevolent Society ((1920), 265 Fed. 397). It is apparent from the language of section 301 that no change is made in the application of State law for this purpose. The section states that—
“suits for violation of contracts concluded ... in an industry affecting commerce . . . may be brought in any district court of the United States ....
“Every district court would still be required to look to State substantive law to determine the question of violation. This section does not, therefore, create a new cause of action but merely makes the existing remedy available to more persons by removing the requirements of amount in controversy and of diversity of citizenship where interstate commerce is affected.
“. . . the Federal courts would be made an available tribunal for every petty cause of action between citizens of the same State, and, undoubtedly in many instances, residents of the same community, *537with application by the Federal judge of exactly the same principles of law which would govern the controversy if it were brought before a State judge in the more numerous State courts.
“Added to these practical objections, are serious questions concerning the legality of abandoning the diversity-of-citizenship requirement. The Constitution limits suits in the Federal courts, inter alia, to cases arising under the Constitution and laws of the United States or involving diversity of citizenship (Constitution, art. Ill, sec. 2).
“Reflection upon these practical and legal objections to this phase of the bill lead to the conclusion that very little useful purpose would be served by making Federal courts more broadly available for the adjudication of disputes under collective-bargaining agreements. The only advantage, if indeed it may be called an advantage, is to give many disputing parties an otherwise unavailable opportunity to choose a Federal forum rather than a State forum. The substantive law governing the settlement of the dispute would not be changed in the least no matter which forum were chosen. It is our conviction that the added burdens upon the Federal courts and the doubtful legality of this measure constitute an extravagant price to pay for a needless indulgence benefiting litigants whose remedies are now as adequate in the State courts as they would be in the Federal courts.” (Pp. 13-14.)
4. Senate debates:
a. Senator Taft:
“Mr. President, title III of the bill, on page 53, makes unions suable in the Federal courts for viola*538tion of contract. As a matter of law unions, of course, are liable in theory on their contracts today, but as a practical matter it is difficult to sue them. They are not incorporated; they have many members; in some States all the members must be served; it is difficult to know who is to be served. But the pending bill provides they can be sued as if they were corporations and if a judgment is found against the labor organization, even though it is an unincorporated association, the liability is on the labor union and the labor-union funds, and it is not on the individual members of the union, where it has fallen in some famous cases to the great financial distress of the individual members of labor unions.” (93 Cong. Rec. 3839.)
“What is the purpose of title III? The purpose of title III is to give the employer and the employee the right to go to the Federal courts to bring a suit to enforce the terms of a collective-bargaining agreement — exactly the same subject matter which is contained in titles I and II. It is impossible to separate them.” (Id., at 4141.)
“Finally, we have a provision in title III for bringing a lawsuit for breach of contract. Breach of what kind of contract? Breach of contract for collective bargaining.” (Id., at 4262.)
“The Senator from Oregon, when speaking about paragraph (5) [§ 8 (b)(5)] on page 16, stated clearly that for the purpose of enforcing the collective-bargaining agreement we were duplicating the two remedies, one by lawsuits in court for violation of an agreement and the other by making the violation of the agreement an unfair labor practice. I do not think that is a legitimate objection to such an amendment.” (Id., at 4437.)
*539b. Senator Ball:
“Fourth, we give to employers the right to sue a union in interstate commerce, in a Federal court, for violation of contract. It does not go beyond that. As a matter of law, I think they have that right, now, but because unions are voluntary associations, the common law in a great many States requires service on every member of the union, which is very difficult; and, if a judgment is rendered, it holds every member liable for the judgment.
“The pending measure, by providing that the union may sue and be sued as a legal entity, for a violation of contract, and that liability for damages will lie against union assets only, will prevent a repetition of the Danbury Hatters case, in which many members lost their homes because of a judgment rendered against the union which also ran against individual members of the union.” (Id., at 5014.)
c. Senator Smith:
“I now come to title III, which is very brief, and merely provides for suits by and against labor organizations, and requires that labor organizations, as well as employers, shall be responsible for carrying out contracts legally entered into as the result of collective bargaining. That is all title III does. I cannot conceive of any sound reason why a party to a contract should not be responsible for the fulfillment of the contract; it is outside my comprehension how anyone can take such a position.
“I have heard it argued that it is a terrible thing to make labor unions responsible for carrying out their contracts, but I have a quotation here, if I can find it, from Mr. Justice Brandéis, who was the greatest friend of labor in the Federal judicial field. *540He said the greatest thing labor could do would be to recognize its responsibility. This is a quotation from an address delivered by him before the Economic Club of Boston on December 4, 1902:
“The unions should take the position squarely that they are amenable to law, prepared to take the consequences if they transgress, and thus show that they are in full sympathy with the spirit of our people, whose political system rests upon the proposition that this is a government of law, and not of men.
“I cannot see how anyone can take issue with so clear-cut a statement as that, or can take issue with the provisions of title III, which simply carry out the idea, by providing that whichever side is guilty of violating a contract solemnly entered into shall be responsible for damages resulting from such violation.
“All that has been done in title III of the pending bill is to state, in terms, the very principle that Mr. Brandéis lays down as a precept to be followed by unions who desire to be respected in the community.” {Id., at 4281-4282.)
d. Senator O’Daniel:
“I believe that labor unions should be made responsible under the laws with which other citizens must comply. I do not think anyone is justified in giving labor unions legal immunity when they practice coercion, or when they seek to exercise the secondary boycott, or when they engage in violence, or when they seek to evade their responsibility for damages with which they may rightly be charged. There is no reason on earth why we should allow labor unions special exemption from laws with which all other citizens must comply.” {Id., at 4758.)
*541e. Senator Murray read, word for word with minor exceptions, the material contained in the Senate minority report, quoted above (II. B. 3. b.), which stressed the fact that Federal courts would be required to look to state law, and that a serious constitutional problem would be involved. (Id., at 4033.) At a later point, in connection with a substitute bill proposed by the minority, he said:
“We of the minority do not see the wisdom of permitting suits in the Federal courts concerning the violation of collective-bargaining agreements regardless of the amount involved or of the constitutional requirement of diversity of citizenship. It is clear that the Federal courts are already open to these suits where the present Federal requirements are met, and we object to burdening them with a host of petty litigation not heretofore countenanced in any way. The State courts are adequate for the purposes of these petty suits. We have nonetheless found that there is a present inability of Federal courts to permit union assets to be reached easily in the few States where the application of State procedural laws prevent suits against unincorporated associations. For this reason section 601 would grant jurisdiction in otherwise justiciable contract actions where suit is brought by or against a union in its common name.” (Id., at 4906.)
f. Senator Thomas:
“Or consider the provisions which open the Federal courts to damage suits for breach of collective bargaining agreements. Not content with the unfair labor practice provisions relative to breaches of collective-bargaining agreements, the authors of S. 1126 now propose to give the Government two bites at the cherry. It must be remembered that *542these provisions do not, in fact, give a remedy where none previously existed, although some care has been taken to create the impression that they do. What these provisions really do is to invite the Federal district courts to police the parties in their adherence to their collective-bargaining agreements by dispensing with the sensible statutory requirement of a jurisdictional amount of $3,000 and the constitutional requirement of diversity of citizenship. I am firmly convinced that this is a vain effort, because I am sure that the suits contemplated by these provisions will not be regarded by the courts as presenting any Federal question. . . .” {Id., at 4768.)
g. Senator Morse:
“One procedure is found in the title which permits, of course, suits by employers against unions for breach of contract. That is subject to a great deal of criticism on the part of unions. I do not think the criticism is well founded, because in my opinion, when union officials sign a labor contract, their signature ought to be given the same sanctity and the same effect as the signature of an employer. So I am going along with the proposal for legislation which permits suits for breach of contract against unions. I think a careful reading by labor leaders of the particular proposal contained in the bill will dispel their minds of many of the exaggerated fears they seem to entertain. But, be that as it may, I think it is only fair and proper that when unions damage the property rights of employers or third parties as the result of breaches of contract, they should be held responsible for the obligation they took unto themselves when they signed the contract.” (Id., at 4207.)
*543h. Other references to the section are of little importance here. (Id., at 3838, 4030, 4148, 4209, 4358, 4986, 5007, and 6454.)
5. Section 301 remained unchanged in the bill as it passed the Senate.
C. Conference Report (H. R. Rep. No. 510, 80th Cong., 1st Sess.):
1. The Conference’s revised Section 301 was that presently in force.
2. The Report stated:
“Suits By and Against Labor, Organizations
“Section 302 of the House bill and section 301 of the Senate amendment contained provisions relating to suits by and against labor organizations in the courts of the United States. The conference agreement follows in general the provisions of the House bill with changes therein hereafter noted.
“Section 302 (a) of the House bill provided that any action for or proceeding involving a violation of a contract between an employer and a labor organization might be brought by either party in any district court of the United States having jurisdiction of the parties, without regard to the amount in controversy, if such contract affected commerce, or the court otherwise had jurisdiction. Under the Senate amendment the jurisdictional test was whether the employer was in an industry affecting commerce or whether the labor organization represented employees in such an industry. This test contained in the Senate amendment is also contained in the conference agreement, rather than the *544test in the House bill which required that the ‘contract affect commerce.'
“Section 302 (b) of the House bill provided that any labor organization whose activities affected commerce should be bound by the acts of its agents and might sue or be sued as an entity in the courts of the United States. Any money judgment in such a suit was to be enforceable only against the organization as an entity and against its assets and not against any individual member or his assets. The conference agreement follows these provisions of the House bill except that this subsection is made applicable to labor organizations which represent employees in an industry affecting commerce and to employers whose activities affect commerce, as later defined. It is further provided that both the employer and the labor organization are to be bound by the acts of their agents. This subsection and the succeeding subsections of section 301 of the conference agreement (as was the case in the House bill and also in the Senate amendment) are general in their application, as distinguished from subsection (a).” (Pp. 65-66.)
D. Debate on the Conference Report:
1. House:
a. Representative Case:
“The Taft-Hartley bill incorporates some other provisions which were in the Case bill of last year and which are pretty much accepted as proper subjects of legislation.
“For instance, the bill establishes suability for and by labor organizations as entities. The bill last year did that. The objection to suits against labor *545organizations has stemmed from a proper resentment against the travesty that took place in the old Danbury Hatters case where individual members of a union were harried and their property attached to satisfy a judgment for action taken by officers whom they did not control. It was as bad as such action would be against minority and individual stockholders of a corporation for acts they could not control. Both in the bill last year, and in this Taft-Hartley bill, the language while making labor organizations responsible under their contracts and for the acts of their agents, limits judgments to the assets of the organization itself.” (93 Cong. Rec. 6283.)
2. Senate: None.
E. Veto Message (H. R. Doc. No. 334, 80th Cong., 1st Sess.):
“It would discourage the growing willingness of unions to include ‘no strike’ provisions in bargaining agreements, since any labor organization signing such an agreement would expose itself to suit for contract violation if any of its members engaged in an unauthorized ‘wildcat’ strike.” (P. 3.)
“The bill would invite unions to sue employers in the courts regarding the thousands of minor grievances which arise every day over the interpretation of bargaining agreements. . . .” (P. 4.)
“At the same time it would expose unions to suits for acts of violence, wildcat strikes and other actions, none of which were authorized or ratified by them. . . .” (P. 5.)
*546F. Subsequent debate:
1. House:
a. Representative Robsion:
“For a number of years high, responsible labor leaders have stated over and over that they believe in the observance of contracts by both parties. One of the purposes of organizing and collective bargaining is to make a contract by management and the workers. This bill provides that management and labor each shall fairly and honestly live up to the terms of their contract and if either party breaks the contract and the other suffers loss or damage thereby, the party who is at fault must respond in fair and just damages. If the parties do not intend to live up to their contract, why should they take the time, trouble, and incur expense of making a contract? . . .” (93 Cong. Rec. 7491.)
2. Senate:
a. Senator Taft:
“This is a perfectly reasonable bill in every respect. If we are to have free collective bargaining it must be between two responsible parties. Some of the provisions of this bill deal with the question of making the unions responsible. There is no reason in the world why a union should not have the same responsibility that a corporation has which is engaged in business. So we have provided that a union may be sued as if it were a corporation. . . .” (Id., at 7537.)
[This opinion applies also to No. 276, General Electric Co. v. Local 205, United Electrical, Radio & Machine Workers, post, p. 547, and No. 262, Goodall-Sanford, Inc. v. United Textile Workers, post, p. 550.]
“Sec. 301. (a) Suits for violation of contracts between an employer and a labor organization representing employees in an industry affecting commerce as defined in this Act, or between any such labor organizations, may be brought in any district court of the United States having jurisdiction of the parties, without respect to the amount in controversy or without regard to the citizenship of the parties.
“(b) Any labor organization which represents employees in an industry affecting commerce as defined in this Act and any employer whose activities affect commerce as defined in this Act shall be bound by the acts of its agents. Any such labor organization may sue or be sued as an entity and in behalf of the employees whom it represents in the courts of the United States. Any money judgment against a labor organization in -a district court of the United States shall be enforceable only against the organization as an entity and against its assets, and shall not be enforceable against any individual member or his assets.
“(c) For the purposes of actions and proceedings by or against labor organizations in the district courts of the United States, district courts shall be deemed to have jurisdiction of a labor organization (1) in the district in which such organization maintains its principal office, or (2) in any district in which its duly authorized officers or agents are engaged in representing or acting for employee members.
“(d) The service of summons, subpena, or other legal process of any court of the United States upon an officer or agent of a labor organization, in his capacity as such, shall constitute service upon the labor organization.
“(e) For the purposes of this section, in determining whether any person is acting as an ‘agent’ of another person so as to make such other person responsible for his acts, the question of whether the specific acts performed were actually authorized or subsequently ratified shall not be controlling.”
At the Seamen’s Union convention in 1923, at a time when the proposed Arbitration Act contained no exemptions, Furuseth, after referring to the effect of the Act on individual contracts, stated:
“So far we have dealt with the individual. What about those, who shall seek to protect themselves through mutual aid? Some organizations are very strong in their cohesiveness. Cannot those organizations save not only the individuals but themselves?
“The Supreme Court has decided that voluntary organizations may be sued. If they shall enter into an agreement containing an arbitration clause, there can be little doubt that the organization will be bound.” Proceedings of the 26th Annual Convention of the International Seamen’s Union of America, p. 204 (1923).
The reference was to this Court’s decision, the previous year, in United Mine Workers v. Coronado Coal Co., 259 U. S. 344.
In view of the course that this litigation has taken, I put to one side the bearing of the Norris-LaGuardia Act. It is not the first time that unions have conveniently disregarded, when it suited an immediate end, their vehement feelings that secured the restriction upon the federal courts in granting injunctions in labor disputes. Candor compels me to say that I do not think that the conclusion reached by Judge Bailey Aldrich in Local 205 v. General Electric Co., 129 F. Supp. 665, has been persuasively met.
Osborn might possibly be limited on the ground that a federal instrumentality, the Bank of the United States, was involved, see n. 5, infra, but such an explanation could not suffice to narrow the holding in the Pacific Railroad Removal Cases.
To be sure, the Court upheld the removal statute for suits or prosecutions commenced in a state court against federal revenue officers on account of any act committed under color of office. Tennessee v. Davis, 100 U. S. 257. The Court, however, construed the action of Congress in defining the powers of revenue agents as giving them a substantive defense against prosecution under state law for commission of acts “warranted by the Federal authority they possess.” Id., at 263. That put federal law in the forefront as a defense. In any event, the fact that officers of the Federal Government were parties may be considered sufficient to afford access to the federal forum. See In re Debs, 158 U. S. 564, 584-586; Mishkin, 53 Col. L. Rev., at 193: “Without doubt, a federal forum should be available for all suits involving the Government, its agents and instrumentalities, regardless of the source of the substantive rule.”
Enunciation of such a requirement could in fact bring federal law somewhat further to the forefront than was true of Osborn, the Pacific Railroad Removal Cases, or the bankruptcy cases in the few cases where an assertion could be made that state law did not sufficiently recognize collective agreements as contracts. But there appears to be no State that today possesses such a rule. Most and probably all cases arising under § 301 — certainly the present ones— would never present such a problem.
In No. 276, respondent’s motion in the Court of Appeals to amend its complaint to show diversity of citizenship was denied on alternate grounds of possible mootness and Rule 17 (b) ’s reference of questions of capacity to sue to state law. The view of § 301 that I have set forth would permit that section to be applied constitutionally to situations, such as diversity of citizenship, where there is jurisdiction in the federal courts apart from § 301. I would therefore remand this case to permit the amendment alleging diversity of citizenship.
