dissenting:
The decision in this case mutilates principles that have long been regarded as basic in the law. New legal doctrines have been more universally accepted than those recognizing the powers which this Court now denies to the states when suits under the Federal Employers’ Liability Act are brought in state courts: the power of a court to prevent injustice by restraining a person subject to its *709authority from maintaining an inequitable suit in the courts of another state, Cole v. Cunningham, 133 U. S. 107; the right of a court to decline its facilities to a suit that “in the interest of justice” should be tried elsewhere, Canada Malting Co. v. Paterson Co., 285 U. S. 413, 422-23. The decision disregards the constitutional relationship between the “judicial power” of the federal government and that of the states whereby state courts enforce federal rights (when such remedies have not been exclusively entrusted to the federal courts) as part of their “duty to safeguard and enforce the right of every citizen without reference to the particular exercise of governmental power from which the right may have arisen.” Minneapolis & St. Louis R. Co. v. Bombolis, 241 U. S. 211, 222.
For a decision so far-reaching in its implications, warrant is found in the inarticulate radiations of § 6 of the 1910 amendment to the Federal Employers’ Liability Act. While the words of a statute do not by themselves distil its meaning, we must at least begin with them. The language of § 6 is simple and direct. After establishing a two-year period of limitations, it continues: “Under this Act an action may be brought in a circuit court of the United States, in the district of the residence of the defendant, or in which the cause of action arose, or in which the defendant shall be doing business at the time of commencing such action. The jurisdiction of the courts of the United States under this Act shall be concurrent with that of the courts of the several States, and no case arising under this Act and brought in any state court of competent jurisdiction shall be removed to any court of the United States.” 36 Stat. 291.
This is a conventional provision. There is nothing novel or distinctive about it. Recognition of concurrent jurisdiction in the state courts to vindicate federal rights is found in the first Judiciary Act of 1789. 1 Stat. 73, 77. *710And the statute books are replete with instances in which Congress has acknowledged the existence of this jurisdiction in the state courts unless explicitly withheld from them. See the discussion of Mr. Justice Bradley in Claflin v. Houseman, 93 U. S. 130, 139-43. The essence of § 6 is merely that the state courts are open to a plaintiff suing under the Act, and that if he chooses to bring suit in a state court, the defendant may not remove the cause to a federal court. So far as language conveys ideas, the Act affords no intimation that Congress intended anything more.
We are not of course concerned here, as we were in the Kepner case, decided the other day, 314 U. S. 44, with an attempt by a state court to prevent resort to a federal court. Historically, the problem of interferences, direct or indirect, between federal and state courts is entirely separate from the problem of the relations of the state courts to each other. See Warren, Federal and State Court Interference, 43 Harv. L. Rev. 345. The question now before us — relating to the power of a state to enjoin those subject to its jurisdiction from unjustly resorting to the courts of a sister state — is an aspect of the latter problem. In the Kepner case, this Court held only that the provision of § 6 “filled the entire field of venue in federal courts” and that what had thus been legislatively given to the federal courts could not judicially be taken away. The Kepner decision cast no cloud upon Douglas v. New York, N. H. & H. R. Co., 279 U. S. 377, which sustained the power of a state to apply the principle of forum non conveniens to suits under the Act brought in its courts by non-residents. The issue in the case at bar is essentially another phase of the problem in the Douglas case — whether, merely by authorizing access to the state courts to enforce rights created by the Federal Employers’ Liability Act, Congress impliedly repealed pro tatito the means for *711achieving justice which the states customarily employ in similar cases. Specifically, the question for decision is this: Has Congress, by providing explicitly that state courts shall have concurrent jurisdiction of suits under the Act, withdrawn from each state its recognized power to enjoin persons within its jurisdiction from bringing a suit under the Act “contrary to equity and good conscience” in the courts of another state? This question was wholly outside the scope of the Kepner case. It was not presented, and was therefore not decided, by that case.
The relevant circumstances here are these. A resident of Tennessee was killed in a railroad accident occurring in Tennessee. The railroad, an Illinois corporation, has its principal offices in Tennessee. All of the witnesses reside in Tennessee, as do the deceased’s legal representatives. But suit was brought in a state court of Missouri, where the railroad does some business. Finding that the Missouri suit was “oppressive and inequitable,” the Tennessee Court of Appeals sustained the power of the chancellor to restrain the further prosecution of that suit. The finding that the Missouri suit was “oppressive and inequitable” was challenged by the petitioners neither before us nor in the courts of Tennessee, and the propriety of the action taken by the Tennessee cqurt, as a matter of equitable discretion, is not here in issue. We are called upon to decide only whether Congress has deprived Tennessee of the power which it has asserted in this case.
It is admitted that the courts of Tennessee customarily exercise this power in situations like the present case. See American Express Co. v. Fox, 135 Tenn. 489, 187 S. W. 1117. If the accident here had occurred while the deceased was engaged in intrastate commerce, and consequently had not given rise to a right of action under the federal statute, Tennessee would unquestionably have *712had the power to do what she has done here. For while the Privileges and Immunities Clause, Art. IV, § 2, secures to citizens of other states such right of access to the courts of a state as that state gives to its own citizens, Chambers v. Baltimore & Ohio R. Co., 207 U. S. 142, 148; McKnett v. St. Louis & S. F. Ry. Co., 292 U. S. 230, 233, it does not take away from a state its historic power to prevent unjust resort to the courts of another state. Cole v. Cunningham, 133 U. S. 107. Moreover, the Constitution would not prevent Missouri from declining to entertain a suit to vindicate a federal right, such as was brought here, if an action to enforce a similar non-federal right would also not lie in her courts. The availability of state courts for the enforcement of federal rights has not resulted in putting federal rights on any different footing from state rights. “A state may not discriminate against rights arising under federal laws,” McKnett v. St. Louis & S. F. Ry. Co., supra, at 234, but neither the Constitution nor Congress has compelled the states to discriminate in favor of federal rights. And this Court has expressly held that the rights created by the Federal Employers’ Liability Act are not different, in this respect, from other federal rights. “As to the grant of jurisdiction in the Employers’ Liability Act, that statute does not purport to require State Courts to entertain suits arising under it, but only to empower them to do so, so far as the authority of the United States is concerned.” Douglas v. New York, N. H. & H. R. Co., supra, at 387.
The utilization of state courts for the vindication of federal rights does not require that their established procedures be remodelled or that their customary modes for administering justice be restricted. “And it was of course presumably an appreciation of the principles so thoroughly settled which caused Congress in the enactment of the Employers’ Liability Act to clearly contemplate the *713existence of a concurrent power and duty of both Federal and state courts to administer the rights conferred by the statute in accordance with the modes of procedure prevailing in such courts.” Minneapolis & St. Louis R. Co. v. Bombolis, 241 U. S. 211, 218; and see Second Employers’ Liability Cases, 223 U. S. 1, 56. The mere fact that a federal right is the basis of suit cannot therefore deprive the state courts of the power to use their customary procedures for the achievement of justice. In simply taking advantage of the facilities afforded by the courts of the states, Congress cannot be deemed to have altered the settled jurisprudence of the states so as to operate more favorably for federal rights than for similar rights created by the states themselves. Such drastic inroads upon the authority of the states should be made only upon clear Congressional mandate.
The Court finds such a plain command in the Act because Congress has explicitly provided in § 6 that the jurisdiction of the state courts “shall be concurrent” with that of the federal courts. But Congress thereby merely spelt out what has always been unquestioned constitutional doctrine. “It is a general rule that the grant of jurisdiction to one court does not, of itself, imply that the jurisdiction is to be exclusive. . . . Upon the state courts, equally with the courts of the Union, rests the obligation to guard and enforce every right secured by the Constitution and laws of the United States whenever those rights are involved in any suit or proceedings before them.” United States v. Bank of New York Co., 296 U. S. 463, 479; see Claflin v. Houseman, 93 U. S. 130, 136-37, Robb v. Connolly, 111 U. S. 624, 635-37. And in Grubb v. Public Utilities Comm’n, 281 U. S. 470, 476, the Court reaffirmed the doctrine that “the state and federal courts have concurrent jurisdiction of suits of a civil nature arising under the Constitution and laws of the United *714States, save in exceptional instances where the jurisdiction has been restricted by Congress to the federal courts.” The source of these formulations is Hamilton’s classic statement in No. 82 of the Federalist (sesquicentennial ed., p. 536):
“I hold that the State courts will be divested of no part of their primitive jurisdiction, further than may relate to an appeal; and I am even of opinion that in every case in which they were not expressly excluded by the future acts of the national legislature, they will of course take cognizance of the causes to which those acts may give birth. This I infer from the nature of judiciary power, and from the general genius of the system. The judiciary power of every government looks beyond its own local or municipal laws, and in civil cases lays hold of all subjects of litigation betwen parties within its jurisdiction, though the causes of dispute are relative to the laws of the most distant part of the globe. . . . When in addition to this we consider the State governments and the national governments, as they truly are, in the light of kindred systems, and as parts of one whom, the inference seems to be conclusive, that the State courts would have a concurrent jurisdiction in all cases arising under the laws of the Union, where it was not expressly prohibited.”
Therefore, if Congress had been silent with respect to the jurisdiction of state courts of suits arising under the Act, the state courts would still have had such jurisdiction. If it be suggested that by articulating what would otherwise have been implied, Congress must have had some purpose, some interest of emphasis, it would be enough to say that such punctiliousness, and perhaps redundancy, of phrasing is not uncommon in procedural legislation. But, in any event, the legislative history of the 1910 amendment conclusively shows that Congress did not insert this *715provision in order to cut down the normal powers of state courts. The concurrent jurisdiction of the state courts was explicitly defined in order to dissipate an unwarranted doubt as to the right and duty of state courts to entertain suits arising under the Act. Congress wanted to avoid an implication of denial to the state courts of power to entertain cases under the Act, and not to create an implication of denial to the state courts of their traditional powers in dealing with such cases.
The Act of 1908 contained no provision specifically dealing with venue. 35 Stat. 65. On January 7, 1910, Representative Sterling introduced a bill, H. R. 17263, that eventually became the 1910 amendment to the Act. The bill had this provision: “This Act shall not be construed as excluding the exercise of a concurrent jurisdiction of cases arising under the Act by the courts of the several States.” The House Committee on the Judiciary reporting on the bill explained its purpose:
“It is proposed to further amend the act by making the jurisdiction of the courts of the United States ‘concurrent with the courts of the several States.’
“This is proposed in order that there shall be no excuse for courts of the States to follow in the error of . . . Hoxie v. N. Y., N. H. & H. R. R. Co. [82 Conn. 352] (73 Atlantic Rep., 754) in which the court declined jurisdiction upon the ground, inter alia, that Congress did not intend that jurisdiction of cases arising under the act should' be assumed by state courts.
“It is clear under the decisions of the Supreme Court of the United States, that this conclusion of the Connecticut court is erroneous. And the reasons recited by the Connecticut court lead to an opposite conclusion from that which the opinion declares upon the subject. But no harm can come, and much injustice and wrong to suitors may be prevented by an express declaration that *716there is no intent on the part of Congress to confine remedial actions brought under the employers’ liability act to the courts of the United States.” H. Rep. No. 513, 61st Cong., 2d Sess., p. 7.
The Committee also recommended that the wording of the provision be changed to read as follows: “The jurisdiction of the courts of the United States under this act shall be concurrent with that of the courts of the several States.” This language was embodied in the Act.
When the bill came to the floor of the House, Representative Sterling, who was in charge of the measure, underscored the sole reason for the provision:
“The second change in the law provides that the federal courts and the state courts shall have concurrent jurisdiction. I am very sure that they have concurrent jurisdiction as the law is now, but on account of a decision of one of the state courts of Connecticut, where one judge declined to take jurisdiction in a case because it was under a federal statute, the committee thought best to expressly provide in the law that the federal courts and the state courts should have concurrent jurisdiction to avoid the possibility of such a construction in the future.” 45 Cong. Rec. 2253.
In reply to a question as to the Committee’s purpose in recommending this provision, “Did you intend to limit the state courts in any way in this matter?”, the answer was, “Oh, no; just the contrary.” 45 Cong. Rec. 2254.
With these authoritative explanations the bill was passed by the House on February 23, 1910. 45 Cong. Rec. 2260. It was then sent to the Senate and there referred to its Judiciary Committee. The report of that Committee repeated in haec verba the explanation of the provision made by the House Committee. See Sen. Rep. No. 432, 61st Cong., 2d Sess., p. 5. Senator Borah, who steered the bill in the Senate, said:
*717“The amendment which has been proposed in the latter portion of section 6 was necessitated, if that term can properly be used, by reason of a decision of the supreme court of the State of Connecticut. My individual view is that the law is now as the amendment attempts to make it — that is to say, that both the federal and state courts have jurisdiction of this matter — concurrent jurisdiction. ... As I understand the law, unless there is a clause prohibiting or inhibiting the state court it always has concurrent jurisdiction with the federal courts in such a subject-matter as this. The report cites a number of authorities to this effect. But the supreme court of Connecticut refused to assume jurisdiction or to take jurisdiction of the matter, though the well-established legal principle seems to be absolutely different. I do not believe this amendment is necessary. I believe it is thoroughly established that the federal courts and the state courts have concurrent jurisdiction. But in order to avoid courts being misled upon this proposition this specific provision is thought to be necessary in the law.” 45 Cong. Rec. 3995. See also his remarks at 45 Cong. Rec. 4034-35.
The Court appears to draw comfort from the provision of the Act prohibiting removal of a suit from a state court of competent jurisdiction to a federal court. The bill as passed by the House contained no such provision. It was offered as an amendment on the floor of the Senate by Senator Paynter who, in proposing the amendment, made a few remarks that are unenlightening for present purposes. The amendment was approved by the Senate without further discussion. 45 Cong. Rec. 4093. When the bill came back to the House, Representative Clayton, a member of the House Judiciary Committee, explained the purpose of this amendment:
“The real amendment [made by the Senate] and the one that I think is a distinct improvement of the bill, *718certainly more so than the other two, is to add . . . these words: ‘And no case arising under this act and brought in any state court of competent jurisdiction shall be removed to any court of the United States/ And the gentleman, being, as I am, a states-rights Democrat, will certainly say that is a decided improvement upon the bill as it originally passed the House. Furthermore, I say that this amendment will tend to relieve the federal courts of some litigation which can be as well, if not better, determined in the courts of the States/’ 45 Cong. Rec. 4158.
Such a restriction against removal of litigation normally arising in the state courts is not unique in the history of legislation dealing with the business of the lower federal courts. Thirty years earlier, Congress had begun to limit the right of removal to the federal courts. See, e. g., Act of July 12, 1882, § 4, 22 Stat. 162, 163; Act of March 3, 1887, 24 Stat. 552, corrected by Act of August 13, 1888, 25 Stat. 433. The removal prohibition of the 1910 Act must be regarded as a phase of the movement to ease the pressure upon the lower federal courts by curtailing access to them rather than by multiplying unduly the number of federal judges. Nothing warrants the inference that thereby Congress intended a reversal of the historic relation of state courts to one another.
That no expression of Congress, nor the purposes revealed by it outside of the language it employed, calls for a break with the past in giving effect to the 1910 amendment was the conclusion reached by this Court upon the fullest consideration of the significance of the provision. “The amendment, as appears by its language,” it was held in the Second Employers’ Liability Cases, 223 U. S. 1, 56, “instead of granting jurisdiction to the state courts, presupposes that they already possessed it.” Later, in the Douglas case, the Court noted that the amendment “does not purport to require State Courts to entertain suits arising under it, but only to empower them to do so, so far *719as the authority of the United States is concerned.” 279 U. S. at 387. And again in McKnett’s case, 292 U. S. at 233, the Court emphasized that “Congress has not attempted to compel states to provide courts for the enforcement of the Federal Employers’ Liability Act.” In short, every time the question has arisen this Court has recognized that by the 1910 amendment Congress did not write a new chapter in judicial history, nor did it modify the historic function of state courts as agencies for the enforcement of federal rights employing the same instruments for achieving justice as they employ when enforcing rights having their source in state law.
The Court now holds that, where considerations of equity and justice are otherwise compelling, § 6 has deprived the state courts of the power to enjoin a plaintiff from pursuing a suit against a carrier in the courts of any state in which the carrier does business. But a series of decisions following Davis v. Farmers Co-operative Co., 262 U. S. 312, enforces a contrary proposition. In these cases, notably Denver & R. G. W. R. Co. v. Terte, 284 U. S. 284, and Michigan Central R. Co. v. Mix, 278 U. S. 492, suits against a carrier in a state where it did business were nevertheless found to constitute an unjustifiable burden on commerce and therefore could not be maintained. If Congress had conferred obligatory jurisdiction upon the state courts, it would have been entirely beyond the province-of this Court to hold, as it did in these decisions, that a suit in a state court which was given “concurrent jurisdiction” by the 1910 amendment constituted a burden on commerce. To suggest that the grant of “concurrent jurisdiction” repealed the historic powers of equity sanctioned by Cole v. Cunningham, 133 U. S. 107, is to imply that in all these cases the Court disregarded what is now found to be the right of a plaintiff to resort to a state court, unhampered by the authority of the state courts to invoke their familiar equitable powers to restrain oppressive and *720vexatious suits in other state courts. This is to say that in all these eases over a period of years this Court disregarded the jurisdictional requirements of the Federal Employers’ Liability Act. Yet the Act was constantly before the Court, and, it may not be amiss to recall, no member of this Court, in modern times at least, was more familiar with and more mindful of jurisdictional requirements than Mr. Justice Brandéis, who spoke for a unanimous Court in both the Davis and Mix cases.
The Court does not now overrule these decisions. They stand as unchallenged authorities that, in giving the state courts concurrent jurisdiction of suits under the Act, Congress did not thereby preclude the application of principles of equity and justice to such suits. These decisions show clearly that § 6 did not give the state courts compulsive jurisdiction; it merely conferred authority to be administered in the context of existing law.
The power invoked by Tennessee in this case was a familiar head of equity jurisdiction long before the Constitution. Injunctions by the chancellor against suits in other courts go back to at least the late sixteenth century. See Cliffe v. Turnor, Cary 83 (1579); Chock v. Chea, Cary 83 (1579); Tanfield v. Davenport, Tot. 114 (1638); Trinick v. Bordfield, Tot. 117 (1638). When Lord Chancellor Clarendon in 1677 refused to enjoin a foreign attachment, Love v. Baker, Ch. Cas. 67, the reporter noted that “all the bar was of another opinion. It was said, the injunction did not lie for foreign jurisdictions, nor out of the king’s dominions. But to that it was answered, the injunction was not to the court, but to the party.” The opinion of the bar soon became the accepted law of England. In the leading case of Lord Portarlington v. Soulby, 3 Myl. & K. 104, Brougham, L. C., expressed the historic doctrine of equity jurisdiction. Referring to the attitude of the bar towards Love v. Baker, he commented: “A very sound answer, as it appears to me; for the same argument might *721apply to a Court within this country, which no order of this Court - ever affects to bind, our orders being only pointed at the parties to restrain them from proceeding. Accordingly, this case of Love v. Baker has not been recognized or followed in later times.” 3 Myl. & K. at 107. See Wharton v. May, 5 Ves. Jr. 27; Kennedy v. Earl of Cassillis, 2 Swans. 313; Harrison v. Gurney, 2 Jac. & W. 563; Bushby v. Munday, 5 Madd. 184; Beauchamp v. Marquis of Huntley, Jac. 546; Eden on Injunctions (1822 ed.) pp. 3 et seq., 101-02.
This doctrine of equitable power has been universally accepted by American courts. See, e. g., Dehon v. Foster, 4 Allen 545, 550; Cole v. Young, 24 Kan. 435, 438; Bigelow v. Old Dominion Co., 74 N. J. Eq. 457, 473, 71 A. 153. And the power has been exercised by the state courts generally to enjoin oppressive suits brought under the Act in other state courts. See Reed’s Admrx. v. Illinois Central R. Co., 182 Ky. 455, 206 S. W. 794; Chicago, M. & St. P. Ry. Co. v. McGinley, 175 Wis. 565, 185 N. W. 218; State ex rel. New York, C. & St. L. R. Co. v. Nortoni, 331 Mo. 764, 55 S. W. 2d 272; Kern v. Cleveland, C., C. & St. L. Ry. Co., 204 Ind. 595, 185 N. E. 446. Of course, since a federal right is involved, no state court can screen denial of or discrimination against a federal right, under the guise of enforcing its local law. Davis v. Wechsler, 263 U. S. 22; Southern Ry. Co. v. Painter, 314 U. S. 155, 159-60.
The power of equity to restrain the prosecution of unconscionable suits has been part of the very fabric of the state courts as we have known them in our whole history. And nothing in the Federal Employers’ Liability Act, its language, its history, or its policy, warrants a denial of this power to the states.
The Chief Justice, Mr. Justice Roberts and Mr. Justice Byrnes join in this dissent.
