concurring:
The posture of the case, the order of my writing and the outcome are, if not unique, at least unusual. A two-to-one majority at the panel level held unconstitutional a labor union’s practice of using agency fees, received from employees who were not union members, for purposes unrelated to collective bargaining, grievance adjustment, or contract administration. Alternatively, the majority concluded that the union’s conduct had violated § 8(a)(3) of the National Labor Relations Act, 29 U.S.C. § 158(a)(3). The non-member employees were entitled to relief for that violation, in the majority’s view, on two theories: first, that § 8(a)(3) itself provided them with a cause of action justiciable in the federal courts, and, second, that the definition of an unfair labor practice contained in § 8(a)(3) also de*1283scribed a breach of the duty of fair representation.3 Judge Russell authored the majority opinion, with Judge Chapman concurring. Beck v. Communications Workers of America, 776 F.2d 1187 (4th Cir.1985).
Chief Judge Winter, in dissent, concluded that the absence of government action foreclosed the constitutional route to recovery, and that § 8(a)(3), involving only controversies between employers and employees, created no restriction on a union’s authority to use agency fees for non-collective-bargaining purposes. He further concluded that, in the absence of a violation of § 8(a)(3), there could be no breach of the duty of fair representation, and that, in any event, the plaintiffs had no cause of action based on § 8(a)(3) itself, due to the National Labor Relations Board’s exclusive jurisdiction to deal with unfair labor practices under the doctrine of San Diego Building Trades Council v. Garmon, 359 U.S. 236, 245, 79 S.Ct. 773, 779, 3 L.Ed.2d 775 (1959). Id. at 1214-25.
A grant of rehearing en banc, of course, eliminated the panel level decisions as grounds for disposing of the case. Back at square one, the court divided six to four. Judge Widener, Judge Ervin and Judge Wilkinson joined Judge Russell and Judge Chapman on one side of the great divide, while Judge Hall, Judge Phillips and Judge Sprouse aligned themselves with Judge Winter.
I find myself in an odd position. On the two issues addressed by my brothers, I find myself in Chief Judge Winter’s camp. In my view, governmental authority cannot be ascribed to the union here, and hence there can . be no constitutional violation. Nor, I believe, does § 8(a)(3) in itself prohibit unions from spending agency fees for purposes unrelated to collective bargaining, grievance adjustment, or contract administration. Those arguments are fully adequate to rebut the contentions marshalled by Judge Russell. However, another set of considerations, raised by the plaintiffs4 but *1284not dealt with by Chief Judge Winter or by Judge Russell, has led me to the conclusion that the plaintiffs should prevail. It is one thing to be out of step with everyone but Johnny. It is even more lonely to find my vote the casting one, where that status derives from its alignment with five votes in favor of a rationale I disagree with and its opposition to four votes whose rationale, to the extent expressed, I approve.
I.
The plaintiffs are twenty employees of the American Telephone and Telegraph Company and the Chesapeake & Potomac Telephone Company. Both employers have negotiated collective bargaining agreements with the Communications Workers of America (CWA). Both collective bargaining agreements contain an “agency shop” provision, which requires the employer to deny employment to any employee who refuses either to join the CWA or to pay the CWA agency fees equivalent to union dues. The plaintiffs are employees who are not members of the union, and who have regularly paid the required agency fees. The CWA and its locals use a part of the fees paid by the plaintiffs for purposes unrelated to collective bargaining, contract administration, or grievance adjustment.
The plaintiffs filed the present action in the United States District Court for the District of Maryland in June 1976. The plaintiffs alleged that the CWA had violated both its statutory duty of fair representation and the plaintiffs’ First Amendment rights of freedom of expression by executing and enforcing the agency shop provisions in such a manner as to coerce the plaintiffs into paying fees which are not used for collective bargaining purposes. Although the union had adopted an internal procedure for the refund of the appropriate portion of dues and fees to employees who objected to such expenditures, the plaintiffs contended that the procedure was inadequate. The plaintiffs sought a declaratory judgment establishing the illegality of the exaction of fees for non-collective-bargaining purposes, an injunction against the CWA’s continued use of agency fees for such purposes, and a monetary judgment for fees collected and used for such purposes in the past.
The CWA moved to dismiss the action because of the plaintiffs’ failure to exhaust internal union procedures for resolving the dispute, or, in the alternative, for a stay pending such exhaustion. The district court denied the motion. Beck v. Communications Workers of America, 468 F.Supp. 87, 90-91 (D.Md.1979). The district court reasoned that deferral to the union’s internal rebate procedure was not warranted where the plaintiffs alleged that the procedure itself violated their rights. The CWA does not appeal that decision.
The district court subsequently decided that the plaintiffs were entitled to the relief they sought. Addressing the question of restitution of amounts previously collected and improperly used, the court ruled that if the parties could not agree upon the sums to be refunded, the court would appoint a special master to make that determination. Beck v. Communications *1285Workers of America, 468 F.Supp. 93, 97 (D.Md.1979).
The parties were unable to agree on the amounts to be refunded, and a master was appointed. In his first report, filed August 18, 1980, the master found that only 19% of the CWA’s total expenditures were made for purposes related to collective bargaining and contract administration, and he recommended that 81% of past agency fees collected by the CWA be refunded to the plaintiffs. The CWA filed exceptions to the report. The district court remanded the matter to the master, directing the master to make specific findings in response to questions prepared by the court. Beck v. Communications Workers of America, 106 LRRM 2323 (D.Md.1981). The master filed a supplemental report in September 1981 which largely reaffirmed his earlier findings. The CWA filed exceptions to the supplemental report.
On March 5,1982, while the district court was considering those exceptions, the union filed a motion under Fed.R.Civ.P. 12(b)(6) to dismiss the complaint for failure to state a claim. The union contended that the plaintiffs’ constitutional claim failed for lack of government action, and that the statutory claim failed because the union’s conduct did not violate the duty of fair representation.
The district court apparently ignored the union’s motion to dismiss, thereby effectively denying the motion. Instead, the district court granted judgment for the plaintiffs for restitution of previously paid agency fees in specified amounts. The district court also permanently enjoined the CWA and its locals from retaining from the plaintiffs in the future the portion of their agency fees certified as non-retainable by an independent certified public accountant.
On appeal, the CWA raised two claims of error. First, it argued that its motion to dismiss the complaint should have been granted. Second, it contended that, if the complaint properly stated a claim, the district court and the special master had applied an erroneous standard of proof in determining the amount of the plaintiffs’ refunds. Judge Russell, joined by Judge Chapman, held that the plaintiffs had properly stated a claim for violation of both their constitutional rights and the requirements of § 8(a)(3); they then went on to agree with the union that an erroneous standard of proof had been applied. The panel therefore voted to vacate some of the special master’s conclusions and to remand the case for further proceedings. Beck v. Communications Workers of America, 776 F.2d 1187 (4th Cir.1985). Chief Judge Winter, in dissent, concluded that the motion to dismiss the complaint should have been granted. Id. at 1214-25.
II.
Chief Judge Winter has, in my opinion, the better of the arguments as to whether the Communications Workers of America, in applying agency fees to non-collective-bargaining purposes, has infringed First Amendment rights of the plaintiffs or breached a statutory duty under § 8(a)(3). I simply do not perceive the existence of governmental action sufficient to invoke the Constitution. Moreover, I agree with Chief Judge Winter that the courts do not have jurisdiction to consider a claim resting directly on § 8(a)(3). Claims based on conduct which arguably amounts to an unfair labor practice under § 8 of the National Labor Relations Act are within the exclusive jurisdiction of the National Labor Relations Board. San Diego Building Trades Council v. Garmon, 359 U.S. 236, 245, 79 S.Ct. 773, 779, 3 L.Ed.2d 775 (1959). While we may, of course, review the unfair labor practice determinations of the NLRB, § 8(a)(3) provides no right of action that is cognizable in the first instance in the federal courts.5
*1286On the other hand, federal courts plainly have jurisdiction to decide claims for violation of a union’s statutory duty of fair representation. Vaca v. Sipes, 386 U.S. 171, 176-88, 87 S.Ct. 903, 909-16, 17 L.Ed.2d 842 (1967). Because that duty does not arise from the NLRA’s unfair labor practice provisions, such claims were originally thought to be outside the scope of the NLRB’s jurisdiction. Somewhat belatedly, the NLRB decided that a union’s breach of its duty of fair representation also constitutes an unfair labor practice under §§ 8(b)(1) and 8(b)(2). Miranda Fuel Co., 140 NLRB 181 (1962), enforcement denied, 326 F.2d 172 (2d Cir.1963). Nevertheless, in Vaca v. Sipes, supra, the Supreme Court explicitly held that the NLRB’s assumption of jurisdiction did not deprive the federal courts of jurisdiction, despite the holding in San Diego Building Trades Council v. Garmon.6 Thus, it is settled that suits for breach of the duty of fair representation, unlike claims based on § 8(a)(3), are cognizable in federal courts.
Chief Judge Winter assumed, however, that the scope of the duty of fair representation, as it relates to the use of agency fees, is merely coextensive with the requirements of § 8(a)(3). He therefore concluded that, in the absence of a violation of § 8(a)(3), the fair representation issue was also necessarily resolved in favor of the union. It is at this point that I part company with Chief Judge Winter’s analysis. The extent of the duty of fair representation is not identical to that of § 8(a)(3). The two statutory obligations are quite distinct. The duty of fair representation does not arise from § 8(a)(3) or from any of the NLRA’s unfair labor practice provisions; rather, it is implicit in the statute as a whole. See Vaca v. Sipes, 386 U.S. 171, 177, 87 S.Ct. 903, 909, 17 L.Ed.2d 842 (1967); Humphrey v. Moore, 375 U.S. 335, 342, 84 S.Ct. 363, 367, 11 L.Ed.2d 370 (1964); Ford Motor Co. v. Huffman, 345 U.S. 330, 337, 73 S.Ct. 681, 685, 97 L.Ed. 1048 (1953).7 Conduct that amounts to an infringement of § 8(a)(3) may also violate the duty of fair representation, but it does not follow that there can be no fair representation breach in the absence of a § 8(a)(3) violation.
An analysis of the application of the duty of fair representation in the present case must begin with the threshold question whether the duty is implicated at all in the collection and spending of agency fees. A union’s duty of fair representation extends only to the union’s conduct in representing employees in dealing with their employer. Kolinske v. Lubbers, 712 F.2d 471, 481 (D.C.Cir.1983). The union must abide by that duty, for example, in negotiating a collective bargaining agreement, Ford Motor Co. v. Huffman, 345 U.S. 330, 73 S.Ct. 681, 97 L.Ed. 1048 (1953), or in adjusting an employee’s grievance, Bowen v. United States Postal Service, 459 U.S. 212, 103 S.Ct. 588, 74 L.Ed.2d 402 (1983); Vaca v. Sipes, 386 U.S. 171, 87 S.Ct. 903, 17 *1287L.Ed.2d 842 (1967). On the other hand, the duty of fair representation does not apply to the union’s treatment of employees within its own internal structure. Bass v. International Brotherhood of Boilermakers, 630 F.2d 1058, 1062-63 (5th Cir.1980).
The duty of fair representation, however, extends to a union’s collection and use of agency fees. If dissenting employees refuse to pay the portion of their fees that is to be used for non-collective-bargaining purposes, the employer is obligated, under the terms of the agency shop clause of the collective bargaining agreement, to discharge them. The matter thus involves the union’s representation of employees in dealing with the employer, thereby implicating the duty of fair representation. In particular, the collection of agency fees from employees who are not union members can hardly be characterized as a purely internal union matter, because the union would have no power to coerce the payment of fees from such employees absent the threat of action by the employer.8
The duty of fair representation imposes on a recognized union an obligation that is fiduciary in nature. Howard v. Aluminum Workers Int’l Union, 589 F.2d 771, 774 (4th Cir.1978); Thompson v. Brotherhood of Sleeping Car Porters, 316 F.2d 191, 201 (4th Cir.1963).9 The union’s exclusive bargaining status, which involves a power to act on behalf of all employees, necessarily creates a relationship of trust. The Supreme Court has explained that the relationship between a union and the employees whom it represents is governed by the “principle of general application that the exercise of a granted power to act in behalf of others involves the assumption toward them of a duty to exercise the power in their interest and behalf.” Steele v. Louisville & Nashville R.R. Co., 323 U.S. 192, 202, 65 S.Ct. 226, 232, 89 L.Ed. 173 (1944). In effect, the union acts as the agent of the employees it represents, union and non-union alike. Humphrey v. Moore, 375, 342, 84 S.Ct. 363, 367, 11 L.Ed.2d 370 (1964); Wallace Corp. v. Labor Board, 323 U.S. 248, 255, 65 S.Ct. 238, 241, 89 L.Ed. 216 (1944). As an agent, the union may not seek to further its own interests at the expense of a principal. Instead, the union must use the fees collected from employees only for purposes within the scope of the agency relationship.
With respect to employees who are not members of the union, the scope of the union’s agency function is defined, not by mutual consent, but by law. Unlike traditional agency relationships, the association between a union and non-member employees is not shaped by the agreement of the parties, but is imposed by statute. Therefore, the scope of the union’s agency function corresponds to the extent of its statutory authority to represent non-member employees. Because that authority is confined to collective bargaining, contract administration or grievance adjustment, it follows that agency fees may be used only for those purposes.10
*1288It is not necessary now to decide whether the scope of the union’s agency function— and hence the extent of its permissible use of employee funds — is the same with respect to union members as it is with respect to non-members. The contractual arrangements between the union and its members are not before us. Nor is it necessary to decide whether a union’s use of members’ dues for purposes outside the scope of its agency function should properly be remediable by the courts, or should be left to be resolved through internal union processes.11 Those questions are not presented here, because none of the plaintiffs are union members.
My conclusion is not foreclosed by the legislative history of the Taft-Hartley Act, which is retraced in Chief Judge Winter’s panel dissent. Beck v. Communications Workers of America, 776 F.2d 1187, 1215-18 (4th Cir.1985). In the first place, it should be borne in mind that the 1947 Congress’ failure to enact legislation imposing limits on union spending is an instance, not of positive action, but of inaction. As the Supreme Court has pointed out, “[o]rdinarily, and quite appropriately, courts are slow to attribute significance to the failure of Congress to act on particular legislation.” Bob Jones University v. United States, 461 U.S. 574, 600, 103 S.Ct. 2017, 2032, 76 L.Ed.2d 157 (1983). “ ‘Unsuccessful attempts at legislation are not the best of guides to legislative intent,’ ” id., quoting Red Lion Broadcasting Co. v. F.C.C., 395 U.S. 367, 382 n. 11, 89 S.Ct. 1794, 1802 n. 11, 23 L.Ed.2d 371 (1969), because, rather than indicating a clear intent, “[c]ongressional inaction frequently betokens unawareness, preoccupation, or paralysis.” Zuber v. Allen, 396 U.S. 168, 185-86 n. 21, 90 S.Ct. 314, 324 n. 21, 24 L.Ed.2d 345 (1969).
Second, insofar as any congressional intent may be discerned from Congress’ failure to act, the legislative history indicates merely that Congress chose not to restrict unions' expenditures of employees’ funds through the use of unfair labor practice provisions. Nothing in the legislative history indicates that Congress intended to preclude the development of such restrictions by the courts under the principles of the duty of fair representation.12 Finally, even if the legislative history of the Act may be read affirmatively to permit union expenditures of members’ dues for purposes unrelated to collective bargaining— thereby foreclosing the possibility of a breach of the duty of fair representation based on such expenditures — the legislative history is altogether silent on the question of union uses of non-members’ agency fees. The provisions of the House bill regulating the “reasonableness” of union exac-tions, which were ultimately rejected by the Conference Committee, were concerned only with members’ dues, and not with fees *1289paid by non-members. H.R. 3020, 80th Cong., 1st Sess. §§ 7(b), 8(c)(2) (1947). The opponents of those provisions, whose view prevailed in the final version of the statute, acted on the basis of a conviction that the government should avoid the policing of internal union affairs, H.R.Rep. No. 245, 80th Cong., 1st Sess. 76 (1947) (minority views); 93 Cong.Rec. 6601 (1947) (statement of Sen. Taft) — not of matters involving outsiders to the union.13 There is simply no indication in the legislative history that Congress intended that unions should be free from legal accountability for their collection and use of non-members’ fees.14 The legislative history, then, poses no obstacle to the view that union expenditures of agency fees collected from non-members for non-collective-bargaining purposes violates the duty of fair representation.
III.
Because I have concluded that the plaintiffs here are entitled to the relief they seek, I must, like Judge Russell and those aligned with him, reach the union’s second assignment of error — their contention that the special master and the district court applied the wrong standard of proof in determining which categories of union expenditures were permissible. On this issue, I agree that the proper standard is one of preponderance of the evidence, Ellis v. Brotherhood of Railway Clerks, 466 U.S. *1290435, 457 n. 15, 104 S.Ct. 1883, 1897 n. 15, 80 L.Ed.2d 428 (1984), and that all disputed factual issues should therefore be remanded for redetermination under the correct standard of proof.
IV.
In recapitulation, it appears, on reading Judge Russell’s en banc opinion, that:
1) The Court has concluded that the plaintiffs are entitled to relief, by a vote of five who find that the defendants have breached a duty imposed on them by § 8(a)(3), and of one who finds no violation of § 8(a)(3), but concludes that the duty of fair representation created principally by § 9(a) has been infringed, as against four who deny any statutory violation.
2) The constitutional grounds asserted as a basis for recovery by the plaintiffs have received support from Judge Russell and Judge Chapman. Five members of the Court (Chief Judge Winter, Judge Hall, Judge Phillips, Judge Sprouse and I) have concluded that no such constitutional basis for relief exists. Three Court members (Judge Widener, Judge Ervin and Judge Wilkinson) have not reached the question, considering it unnecessary to do so in light of the posture of the Court on the statutory issue.
3) By a vote of six, the Court has decided that there must be remanded for a proper allocation as among permissible and impermissible expenditures chargeable to the plaintiffs such items as were not specifically determined in the panel majority opinion to be permissible or unallowable. The remaining four members of the Court have not reached the question.
. The extent to which the panel majority relied . on the duty of fair representation is unclear. On the one hand, the opinion states that "plaintiffs have stated a good cause of action for a violation of ... the duty of fair representation" as well as for a violation of § 8(a)(3). 776 F.2d 1187, 1196. Moreover, the majority plainly concluded that it was the fair representation claim that brought the statutory aspect of the case within this court’s jurisdiction, rather than within the exclusive jurisdiction of the NLRB. Id. at 1203-04. On the other hand, the majority’s rationale for its holding on the statutory issue is explained exclusively in terms of § 8(a)(3) and its relationship to § 2, Eleventh of the Railway Labor Act, with no consideration given to the independent force of the duty of fair representation. In addition, the opinion states that "[ojnly if jurisdiction of these claims under § 8(a)(3) itself is nonexistent would a dismissal of this action ... be appropriate.” Id. at 1196 (emphasis supplied). These somewhat contradictory indications are reconciled, it seems to me, if the opinion is read to hold that a breach of the duty of fair representation follows automatically from a violation of § 8(a)(3). If I have misread Judge Russell, I solicit his indulgence.
. In his dissenting opinion at the en banc level, Chief Judge Winter argues that the issue of the duty of fair representation was neither advanced by the parties nor considered by the panel majority. Post, at 1290. It is true that, in the briefs and oral arguments, the duty of fair representation was overshadowed by the parties’ emphasis on § 8(a)(3). However, that seems to have occurred because the parties, like the panel majority, believed that § 8(a)(3) provided a sort of "standard of care” for the duty of fair representation, and not because they believed that the plaintiffs’ claim rested on § 8(a)(3) alone. A review of the record reveals the inaccuracy of the suggestion that the fair representation issue is of my own devising.
The duty of fair representation was initially raised as a ground for relief in the plaintiffs’ complaint. Supplemental Appendix 15. Moreover, it is noteworthy that, although the issue was raised separately, the complaint also charged that the union’s expenditure of agency fees violated its fiduciary duty to all bargaining unit employees. Id at 12-15. The plaintiffs’ failure, at that stage, to perceive a connection between their claims surely does not prevent this court from doing so.
The question of the duty of fair representation was raised again in the briefs submitted in connection with the initial hearing on áppeal before a panel of this court. The defendants pointed out that because claims based directly on § 8(a)(3) are within the exclusive jurisdiction of the National Labor Relations Board, the plaintiffs would have to find an alternative basis for their statutory claim if they wished this court to consider it. Reply Brief of Appellants/Cross-Appellees 9-10. The plaintiffs responded with the argument that the statutory basis for their *1284claim actually lay in the implied duty of fair representation. Appellees’ Supplemental Brief 2-3. Although the plaintiffs did not clarify their view of the relationship between the basis of their claim in the duty of fair representation and their arguments under § 8(a)(3), the only reasonable interpretation of their position seems to be that they believed that § 8(a)(3) provided a convenient standard by which the presence or absence of a breach of the duty of fair representation could be tested.
Finally, the panel majority’s opinion clearly considered and agreed with the plaintiffs’ arguments concerning the fair representation issue. A close reading of that opinion reveals that the panel majority believed that the plaintiffs had two alternative statutory claims, one based directly on § 8(a)(3), the other based on the duty of fair representation. The panel majority concluded that the union’s expenditure of agency fees was "not only a violation of the statute itself but also a violation of the duty of fair representation.” 776 F.2d at 1203. The majority then explained, in an extensive discussion, that the presence of the fair representation claim provided the court with jurisdiction and defeated the argument that exclusive jurisdiction lay with the NLRB. Id. at 1203-04.
. No similar jurisdictional problem exists with respect to the analogous provision of the Railway Labor Act, § 2, Eleventh, relied on by Judge Russell, which also authorizes the adoption of union shop and agency shop agreements. Unlike § 8(a)(3), § 2, Eleventh is not subject to the jurisdiction of an administrative board. Indeed, there is no administrative board under the RLA whose functions parallel those of the NLRB.
. The Court explained that:
[A] primary justification for the pre-emption doctrine [announced in Garmon] — the need to avoid conflicting rules of substantive law in the labor relations area and the desirability of leaving the development of such rules to the administrative agency created by Congress for that purpose — is not applicable to cases involving alleged breaches of the union’s duty of fair representation____ [A]s these matters are not normally within the Board’s unfair labor practice jurisdiction, it can be doubted whether the Board brings substantially greater expertise to bear on these problems than do the courts,____ Nor do we think that Congress intended to shield employers from the natural consequences of their breaches of bargaining agreements by wrongful union conduct in the enforcement of such agreements. Vaca v. Sipes, 386 U.S. at 180-81, 186, 87 S.Ct. at 911-12, 914.
. Insofar as the statutory source of the duty may be more precisely located, it is to be found in § 9(a) of the Act, which grants to recognized unions the privilege of acting as the exclusive bargaining representative of all employees. Kolinske v. Lubbers, 712 F.2d 471, 481 (D.C.Cir.1983); Local Union No. 12, United Rubber Workers v. N.L.R.B., 368 F.2d 12, 17 (5th Cir.1966); Price v. United Auto Workers, 621 F.Supp. 1243, 1250 (D.Conn.1985). That privilege carries with it the duty to represent all employees fairly. Humphrey v. Moore, 375 U.S. 335, 342, 84 S.Ct. 363, 367, 11 L.Ed.2d 370 (1964); Steele v. Louisville & Nashville R.R. Co., 323 U.S. 192, 200-04, 65 S.Ct. 226, 231-33, 89 L.Ed. 173 (1944).
. The issue here is thus very different from that presented in Kolinske v. Lubbers, 712 F.2d 471 (D.C.Cir.1983), which held that the duty of fair representation was not implicated in a union’s unilateral decision not to distribute strike benefits to non-union employees who honored a picket line but failed to participate in various strike activities. The union’s refusal to pay strike benefits to a non-member who refused to participate in strike activities was properly characterized as an internal union matter because the authority to make and enforce that decision lay solely with the union, and did not depend on, and indeed could hardly count on, the cooperation of the employer.
. Accord, N.L.R.B. v. Local 282, Int'l Brotherhood of Teamsters, 740 F.2d 141, 147 (2d Cir. 1984); Deboles v. Trans World Airlines, 552 F.2d 1005, 1014 (3d Cir.1977); Waiters Union, Local 781 v. Hotel Ass'n, 498 F.2d 998, 1000 (D.C.Cir.1974); Local Union No. 12, United Rubber Workers v. N.L.R.B., 368 F.2d 12, 17 (5th Cir.1966).
. Of course, it is possible that non-member employees might voluntarily choose collaterally to extend the statutory right of representation, and thereby contractually to use the union as their agent for some purpose unrelated to collective bargaining. To that extent, the scope of the union’s agency function would be defined by mutual consent, and could be treated under traditional principles of contract law and agency law. Amounts spent by the union pursuant to such express authorization by non-member *1288employees would not involve a breach of the duty of fair representation.
Here, however, there is no indication of mutual consent extending the union’s authority beyond that spelled out by statute.
. Chief Judge Winter asserts, post at 1292, that ”[a]gency fees are the equivalent of union dues,” and that for the purposes of regulating union expenditures members and non-members should be treated alike. That view overlooks an important distinction between members and nonmembers: members have the right to vote in union elections. By exercising their right to vote, union members can indirectly control the union's spending decisions. Nonmembers, who do not have a right to vote, lack any power over union policymaking and must trust in the good faith of union officials in protecting their interests. The union member’s voting power might or might not justify a determination that the relationship between a union and its members is not sufficiently fiduciary to warrant judicial intervention with respect to expenditures of dues for non-collective bargaining purposes; that question is not before us here. What is clear, however, is that the non-union member, who lacks any means of imposing limits on the freedom of union officials to deal with his compulsory contrihutions, is in a situation quite different from that of the union member and of the kind that traditionally calls for judicial protection.
. Congress was aware, at the time of the enactment of the Taft-Hartley Act in 1947, of the judicial implication of the duty of fair representation under the federal labor statutes. The duty had first been recognized three years earlier in Steele v. Louisville & Nashville R.R., 323 U.S. 192, 65 S.Ct. 226, 89 L.Ed. 173 (1944).
. Congress later overcame many of its objections to governmental intrusion into internal union affairs with the passage of the Labor Management Reporting and Disclosure Act of 1959, 29 U.S.C. § 401 et seq., which established a "bill of rights” for union members against their union leadership.
. Chief Judge Winter argues, post at 1292-1293, that Congress in 1947 consciously adopted a "hands off' approach to unions’ expenditures of agency fees. In my view, that inference is simply too tenuous to be accepted. None of the evidence pointed to by Judge Winter provides any real support for that conclusion. On the contrary, both § 8(d)(4) of the original House bill, reprinted in 2 Legislative History of the Labor Management Relations Act 56-58 (1948), which was a precursor of the present proviso to § 8(a)(3), and the remarks of Senator Taft in the Senate debates, 93 Cong.Rec. § 4400 (April 30, 1947), reprinted in 2 Legislative History of the Labor Management Relations Act 1142 (1948), indicate that their authors were focusing on the question of union membership.
It is true that both the drafters of the House bill and Senator Taft endorsed the union shop, but the union shop is not the same as the agency shop. Both differ from the closed shop in that the employer is not obligated to hire employees only from among persons who are already union members. However, under a union shop arrangement, new employees must become, or at least seek to become, union members within a brief period after their employment commences. While the union may deny them membership, they cannot choose to remain nonmembers. In an agency shop, on the other hand, membership in the union is entirely optional. Judge Winter has pointed to nothing in the legislative history that suggests that Congress consciously focused on the latter kind of arrangement. The portions of the House bill and the Senate debates cited by the dissent reveal a concern for the would-be union member who is denied membership in a union shop arrangement, but they have no bearing on agency shops or agency fees.
No discussion of Congress' intent in the Taft-Hartley Act with respect to agency shop arrangements can ignore the Supreme Court’s decision in NLRB v. General Motors, 373 U.S. 734, 83 S.Ct. 1453, 10 L.Ed.2d 670 (1963). There, the Court held that the proviso to § 8(a)(3), which exempted union shop arrangements from prohibition as an unfair labor practice due to their discriminatory nature, also extended to agency shop agreements. The Court’s decision was undoubtedly correct, but it was not based on a perception that Congress consciously considered the problem of agency shops in 1947. Rather, implicitly acknowledging the lack of evidence of any such conscious consideration, the Court looked to the interpretation that would be most consistent with "the desire of Congress to reduce the evils of compulsory unionism while allowing financial support for the bargaining agent.” Id. at 744, 83 S.Ct. at 1460. While that broad congressional purpose can easily support the conclusion drawn from it in General Motors, it simply cannot, without severe logical strain, be made the basis of an inference that Congress considered and rejected the possibility of any restrictions on unions’ expenditures of agency fees. Indeed, if anything, it cuts the other way: imposing fiduciary responsibilities on unions with respect to agency fee expenditures would tend to reduce the burdens of compulsory unionism for the non-member employee, while at the same time guaranteeing the union financial support for its collective bargaining activities.
