  Mr. Justice Brennan
  delivered the opinion of the Court.
  A group of labor organizations, appellants here, and the carriers comprising the Southern Railway System, entered into a union-shop agreement pursuant to the authority of § 2, Eleventh of the Railway Labor Act. The agreement requires each of the appellees, employees of the carriers, as a condition of continued employment, to pay the appellant union representing his particular class or craft the dues, initiation fees and assessments uniformly required as a condition of acquiring or retaining union membership. The appellees, in behalf of themselves and of employees similarly situated, brought this action in the Superior Court of Bibb County, Georgia, alleging that the money each was thus compelled to pay to hold his job was in substantial part used to finance the campaigns of candidates for .federal and state offices whom he opposed, and to promote the propagation of political and economic doctrines, concepts and ideologies with which he disagreed. The Superior Court found that the allegations were fully proved and entered a judgment and decree enjoining the enforcement of the union-shop agreement on the ground that § 2, Eleventh violates the Federal Constitution to the extent that it permits such use by the appellants of the funds exacted from employees. The Supreme Court of Georgia affirmed, 215 Ga. 27, 108 S. E. 2d 796. On appeal to this Court under 28 U. S. C. § 1257 (1), we noted probable jurisdiction, 361 U. S. 807.
  I.
  The Hanson Decision.
  We held in Railway Employes’ Dept. v. Hanson, 351 U. S. 225, that enactment of the provision of § 2, Eleventh authorizing union-shop agreements between interstate railroads and unions of their employees was a valid exercise by Congress of its powers under the Commerce Clause and did not violate the First Amendment or the Due Process Clause of the Fifth Amendment. It is argued that our disposition of the First Amendment claims in Hanson disposes of appellees’ constitutional claims in this case adversely to their contentions. We disagree. As appears from its history, that case decided only that § 2, Eleventh, in authorizing collective agreements conditioning employees’ continued employment on payment of union dues, initiation fees and assessments, did not on its face impinge upon protected rights of association. The Nebraska Supreme Court in Hanson, upholding the employees’ contention that the union shop could not constitutionally be enforced against them, stated that the union shop “improperly burdens their right to work and infringes upon their freedoms. This is particularly true as to the latter because it is apparent that some of these labor organizations advocate political ideas, support political candidates, and advance national economic concepts which may or may not be of an employee’s choice.” 160 Neb. 669, 697, 71 N. W. 2d 526, 546. That statement was made in the context of the argument that compelling an individual to become a member of an organization with political aspects is an infringement of the constitutional freedom of association, whatever may be the constitutionality of compulsory financial support of group activities outside the political process. The Nebraska court’s reference to the support of political ideas, candidates, and economic concepts “which may or may not be of an employee’s choice” indicates that it was considering at most the question of compelled membership in an organization with political facets. In their brief in this Court the appellees in Hanson argued that First Amendment rights would-be infringed by the enforcement of an agreement which would efiable compulsorily collected funds to be used for political purposes. But there was nothing concrete in the record to show the extent to which the unions were actually spending money for political purposes and what these purposes were, nothing to show the extent to which union funds collected from members were being used to meet the costs of political activity and the mechanism by which this was done, and nothing to show that the employees there involved opposed the use of their money for any particular political objective. In contrast, the present record contains detailed information on all these points, and specific findings were made in the courts below as to all of them. When it is recalled that the action in Hanson was brought before the union-shop agreement became effective and that the appellees never thereafter showed that the unions were actually engaged in furthering political causes with which they disagreed and that their money would be used to support such activities, it becomes obvious that this Court passed merely on the constitutional validity of § 2, Eleventh of the Railway Labor Act on its face, and not as applied to infringe the particularized constitutional rights of any individual. On such a record, the Court could not have done more, consistently with the restraints that govern us in the adjudication of constitutional questions and warn against their premature decision. We therefore reserved decision of the constitutional questions which the appellees present in this case. We said: “It is argued that compulsory membership will be used to impair freedom of expression. But that problem is not presented by this record. ... if the exaction of dues, initiation fees, or assessments is used as a cover for forcing ideological conformity or other action in contravention of the First Amendment, this judgment will not prejudice the decision in that case. For we pass narrowly on § 2, Eleventh of the Railway Labor Act. We only hold that the requirements for financial support of the collective-bargaining agency by all who receive the benefits of its work is within the power of Congress under the Commerce Clause and does not violate either the First or the Fifth Amendments.” Id., p. 238. See also p. 242 (concurring opinion). Thus all that was held in Hanson was that § 2, Eleventh was constitutional in its bare authorization of union-shop contracts requiring workers to give “financial support” to unions legally authorized to act as their collective bargaining agents. We sustained this requirement — and only this requirement — embodied in the statutory authorization of agreements under which “all employees shall become members of the labor organization representing their craft or class.” Clearly we passed neither upon forced association in any other aspect nor upon the issue of the use of exacted money for political causes which were opposed by the employees.
  The record in this case is adequate squarely to present the constitutional questions reserved in Hanson. These are questions of the Utmost gravity. However, the restraints against unnecessary constitutional decisions counsel against their determination unless we must conclude that Congress, in authorizing a union shop under § 2, Eleventh, also meant that the labor organization receiving an employee's money should be free, despite that employee’s objection, to spend his money for political causes which he opposes. Federal statutes are to be so construed as to avoid serious doubt of their constitutionality. “When the validity of an act of the Congress is drawn in question, and even if a serious doubt of constitutionality is raised, it is a cardinal principle that this Court will first ascertain whether a construction of the statute is fairly possible by which the question may be avoided.” Crowell v. Benson, 285 U. S. 22, 62. Each named appellee in this action has made known to the union representing his craft or class his dissent from the use of his money for political causes which he opposes. We have therefore examined the legislative history of § 2, Eleventh in the context of the development of unionism in the railroad industry under the regulatory scheme created by the Railway Labor Act to determine whether a construction is “fairly possible” which denies the authority to a union, over the employee’s objection, to spend his money for political causes which he opposes. We conclude that such a construction is not only “fairly possible” but entirely reasonable, and we therefore find it unnecessary to decide the correctness of the constitutional determinations made by the Georgia courts.
  II.
  The Rail Unions and Union Security.
  The history of union security in the railway industry is marked first, by a strong and long-standing tradition of voluntary unionism on the part of the standard rail unions; second, by the declaration in 1934 of a congressional policy of complete freedom of choice of employees to join or not to join a union; third, by the modification of the firm legislative policy against compulsion, but only as a specific response to the recognition of the expenses and burdens incurred by the unions in the administration of the complex scheme of the Railway Labor Act.
  When the question of union security in the rail industry was first given detailed consideration by Congress in 1934 only one of the standard unions had security provisions in any of its contracts. The Brotherhood of Railroad Trainmen maintained a number of so-called “percentage” contracts, requiring that in certain classes of employees represented by the Brotherhood, a specified percentage of employees had to belong to the union. These contracts applied only to yard conductors, yard brakemen and switchmen, and covered no more than 10,000 workers, about 1% of all rail employees. See letter from Joseph B. Eastman, Federal Coordinator of Transportation, to Chairman of the House Committee on Interstate and Foreign Commerce, June 7, 1934, H. R. Rep. No. 1944, 73d Cong., 2d Sess., pp. 14^16; testimony of James A. Farquharson, legislative representative of the Brotherhood of Railroad Trainmen, Hearings on H. R. 7650, House Committee on Interstate and Foreign Commerce, 73d Cong., 2d Sess., pp. 94-105.
  During congressional consideration of the 1934 legislation, the rail unions attempted to persuade Congress not to preclude them from negotiating security arrangements. By amendments to the original proposal, they sought to assure that the provision which became § 2, Fifth should prevent the carriers from conditioning employment on membership in a company union but should exempt the standard unions from its prohibitions. The Trainmen, the only union which stood to lose existing contracts if the section was not limited to company unions, especially urged such a limitation. See statement of A. F. Whitney, president, S. Rep. No. 1065, 73d Cong., 2d Sess., pt. 2, p. 2; see also 78 Cong. Rec. 12372, 12376.
  The unions succeeded in having the House incorporate such a limitation in the bill it passed. See H. R. Rep. No. 1944, 73d Cong., 2d Sess. 2, 6; 78 Cong. Rec. 11710-11720. But the Senate did not acquiesce. Eastman, a firm believer in complete freedom of employees in their choice of representatives, strongly opposed the limitation. He characterized it as “vicious, because it strikes at the principle of freedom of choice which the bill is designed to protect. The prohibited practices acquire no virtue by being confined to so-called ‘standard unions.' . . . Within recent years, the practice of tying up men’s jobs with labor-union membership has crept into the railroad industry which theretofore was singularly clean in this respect. The practice has been largely in connection with company unions but not entirely. If genuine freedom of choice is to be the basis of labor relations under the Railway Labor Act, as it should be, then the yellow-dog contract, and its corollary, the closed shop, and the so-called ‘percentage contract’ have no place in the picture.” Hearings on S. 3266, Senate Committee on Interstate Commerce, 73d Cong., 2d Sess., p. 157. Eastman’s views prevailed in the Senate, and the House concurred in a final version of § 2, Fifth, providing that “[n]o carrier . . . shall require any person seeking employment to sign any contract or agreement promising to join or not to join a labor organization.” See 78 Cong. Rec. 12369-12376, 12382-12388, 12389-12398, 12400-12402, 12549-12555.
  During World War II, the nonoperating unions made an unsuccessful attempt to obtain union security, incidental to an effort to secure a wage increase. Following the failure of negotiations and mediation, a Presidential Emergency Board was appointed. Two principal reasons were advanced by the unions. They urged that in view of their pledge not to strike for the duration and their responsibilities to assure uninterrupted operation of the railroads, they were justified in seeking to maintain their positions by union security arrangements. They also maintained that since they secured benefits through collective bargaining for all employees they represented, it was fair that the costs of their operations be shared by all workers. The Board recommended withdrawal of the request, concluding that the union shop was plainly forbidden by the Railway Labor Act and that in any event the unions had failed to show its necessity or utility. Presidential Emergency Board, appointed Feb. 20, 1943, Report of May 24, 1943; Supplemental Report, May 29, 1943. The Report said: “[T]he Board is convinced that the essential elements of the union shop as defined in the employees’ request are prohibited by section 2 of the Railway Labor Act. The intent of Congress in this respect is made evident, with unusual clarity.” Supplemental Report, supra, p. 29. On the merits of the issue, the Board expressly rejected the claim that union security was necessary to protect the bargaining position of the unions: “[T]he unions are not suffering from a falling off in members. On the contrary, . . . membership has been growing and at the present time appears to be the largest in railroad history, with less than 10 percent nonmembership among the employees here represented.” Supplemental Report, p. 31. “[T]he evidence presented with respect to danger from predatory rivals seemed to the Board lacking in sufficiency; especially so in the light of the evidence concerning membership growth.” Ibid. “[N]o evidence was presented indicating that the unions stand in jeopardy by reason of carrier opposition. A few railroads were mentioned on which some of the unions do not represent a majority of their craft or class, and do not have bargaining relationships with the carrier. But the exhibits show that these unions are the chosen representatives of the employees on the overwhelming majority of the railroads, and that recognition of the unions is general. The Board does not find therefore that a sufficient case has been made for the necessity of additional protection of union status on the railroads.” Id., p. 32. The unions acceded to the Board’s recommendation.
  The question of union security was reopened in 1950. Congress then evaluated the proposal for authorizing the union shop primarily in terms of its relationship to the financing of the unions’ participation in the machinery created by the Railway Labor Act to achieve its goals. The framework for fostering voluntary adjustments between the carriers and their employees in the interest of the efficient discharge by the carriers of their important functions with minimum disruption from labor strife has no statutory parallel in other industry. That machinery, the product of a long legislative evolution, is more complex than that of any other industry. The labor relations of interstate carriers have been a subject of congressional enactments since 1888. For a time, after World War I, Congress experimented with a form of compulsory arbitration. The experiment was unsuccessful. Congress, has since that time consistently adhered to a regulatory policy which places the responsibility squarely upon the carriers and the unions mutually to work out settlements of all aspects of the labor relationship. That policy was embodied in the Railway Labor Act of 1926, 44 Stat. 577, jvhich remains the basic regulatory enactment. As the Senate Report on the bill which became that law stated: “The question was . . . presented whether the substitute [for the Act of 1920] .should consist of a compulsory system with adequate means provided for its enforcement, or whether it was in the public interest to create the machinery for amicable adjustment of labor disputes agreed upon by the parties and to the success of which both parties were committed. . . . The committee is of opinion that it is in the public interest to permit a fair trial of the method of amicable adjustment agreed upon by the parties, rather than to attempt under existing conditions to use the entire power of the Government to deal with these labor disputes.” S. Rep. No. 606, 69th Cong., 1st Sess., p. 4. The reference to the plan “agreed upon by the parties” was to “the fact that the Railway Labor Act of 1926 came on the statute books through agreement between the railroads and the railroad unions on the need for such legislation. It is accurate to say that the railroads and the railroad unions between them wrote the Railway Labor Act of 1926 and Congress formally enacted their agreement.” Railway Employes’ Dept. v. Hanson, supra, p. 240 (concurring opinion). See generally Murphy, Agreement on the Railroads — The Joint Railway Conference of 1926, 11 Lab. L. J. 823.
  “All through the [1926] act is the theory that the agreement is the vital thing in life.” Statement of Donald R. Richberg, Hearings on H. R. 7180, House Committee on Interstate and Foreign Commerce, 69th Cong., 1st Sess., pp. 15-16. The Act created affirmative legal duties on the part of the carriers and their employees “to exert every reasonable effort to make and maintain agreements concerning rates of pay, rules, and working conditions, and to settle all disputes, whether arising out of the application of such agreements or otherwise . . . .” § 2, First. See Texas & N. O. R. Co. v. Brotherhood of Railway & Steamship Clerks, 281 U. S. 548. The Act also established a comprehensive administrative apparatus for the adjustment of disputes, in conferences between the parties, § 2, Second, Third and Fourth (now Sixth), and if not so settled, in submissions to boards of adjustment, § 3, or the National Mediation Board, § 4. And the legislation expanded the already existing voluntary arbitration machinery, §§ 7, 8, 9.
  A primary purpose of the major revisions made in 1934 was to strengthen the position of the labor organizations vis-a-vis the carriers, to the end of furthering the success of the basic congressional policy of self-adjustment of the industry’s labor problems between carrier organizations and effective labor organizations. The unions claimed that the carriers interfered with the employees’ freedom of choice of representatives by creating company unions, and otherwise attempting to undermine the employees’ participation in the process of collective bargaining. Congress amended § 2, Third to reinforce the prohibitions against interference with the choice of representatives, and to permit the employees to select nonemployee representatives. A new § 2, Fourth was added guaranteeing employees the right to organize and bargain collectively, and Congress made it the enforceable duty of the carriers “to treat with” the representatives of the employees, § 2, Ninth. See Virginian R. Co. v. System Federation, 300 U. S. 515. It was made explicit that the representative selected by a majority of any class or craft of employees should be the exclusive bargaining representative of all the employees of that craft or class. “The minority members of a craft are thus deprived by the statute of the right, which they would otherwise possess, to choose a representative of their own, and its members cannot bargain individually on behalf of themselves as to matters which are properly the subject of collective bargaining.” Steele v. Louisville & N. R. Co., 323 U. S. 192, 200. “Congress has seen fit to clothe the bargaining representative with powers comparable to those possessed by a legislative body both to create and restrict the rights of those whom it represents . . . .” Id., p. 202. In addition to thus strengthening the unions’ status in relation to both the carriers and the employees, the 1934 Act created the National Railroad Adjustment Board and provided that the 18 employee representatives were to be chosen by the labor organizations national in scope. § 3. This Board was given jurisdiction to settle what are termed minor disputes in the railroad industry, primarily grievances arising from the application of collective bargaining agreements to particular situations. See Union Pacific R. Co. v. Price, 360 U. S. 601.
  In sum, in prescribing collective bargaining as the method of settling railway disputes, in conferring upon the unions the status of exclusive representatives in the negotiation and administration of collective agreements, and in giving them representation on the statutory board to adjudicate grievances, Congress has given the unions a clearly defined and delineated role to play in effectuating the basic congressional policy of stabilizing labor relations in the industry. “It is fair to say that every stage in the evolution of this railroad labor code was progressively infused with the purpose of securing self-adjustment between the effectively organized railroads and the equally effective railroad unions and, to that end, of establishing facilities for such self-adjustment by the railroad community of its own industrial controversies. . . . The assumption as well as the aim of that Act [of 1934] is a process of permanent conference and negotiation between the carriers on the one hand and the employees through their unions on the other.” Elgin, J. & E. R. Co. v. Burley, 325 U. S. 711, 752-753 (dissenting opinion).
  Performance of these functions entails the expenditure of considerable funds. Moreover, this Court has held that under the statutory scheme, a union’s status as exclusive bargaining representative carries with it the duty fairly and equitably to represent all employees of the craft or class, union and nonunion. Steele v. Louisville & N. R. Co., 323 U. S. 192; Tunstall v. Brotherhood of Locomotive Firemen & Enginemen, 323 U. S. 210. The principal argument made by the unions in 1950 was based on their role in this regulatory framework. They maintained that because of the expense of performing their duties in the congressional scheme, fairness justified the spreading of the costs to all employees who benefited. They thus advanced as their purpose the elimination of the “free riders” — those employees who obtained the benefits of the unions’ participation in the machinery of the Act without financially supporting the unions.
  George M. Harrison, spokesman for the Railway Labor Executives’ Association, stated the unions’ case in this fashion:
  “Activities of labor organizations resulting in the procurement of employee benefits are costly, and the only source of funds with which to carry on these activities is the dues received from members of the organization. We believe that it is essentially unfair for nonmembers to participate in the benefits of those activities without contributing anything to the cost. This is especially true when the collective bargaining representative is one from whose existence and activities he derives most important benefits and one which is obligated by law to extend these advantages to him.
  “Furthermore, collective bargaining to the railroad industry is more costly from a monetary standpoint than that carried on in any other industry. The administrative machinery is more complete and more complex. The mediation, arbitration, and Presidential Emergency Board provisions of the act, while greatly in the public interest, are very costly to the unions. The handling of agreement disputes through the National Railroad Adjustment Board also requires expense which is not known to unions in outside industry.” Hearings on H. R. 7789, House Committee on Interstate and Foreign Commerce, 81st Cong., 2d Sess., p. 10.
  This argument was decisive with Congress. The House Committee Report traced the history of previous legislation in the industry and pointed out the duty of the union acting as exclusive bargaining representative to represent equally all members of the class. “Under the act, the collective-bargaining representative is required to represent the entire membership of the craft or class, including nonunion members, fairly, equitably, and in good faith. Benefits resulting from collective bargaining may not be withheld from employees because they are not members of the union.” H. R. Rep. No. 2811, 81st Cong., 2d Sess., p. 4. Observing that about 75% or 80% of all railroad employees were believed to belong to a union, the report continued: “Nonunion members, nevertheless, share in the benefits derived from collective agreements negotiated by the railway labor unions but bear no share of the cost of obtaining such benefits.” Ibid. These considerations overbore the arguments in favor of the earlier policy of complete individual freedom of. choice. As we said in Railway Employes’ Dept. v. Hanson, supra, p. 235, “[t]o require, rather than to induce, the beneficiaries of trade unionism to contribute to its costs may not be the wisest course. But Congress might well believe that it would help insure the right to work in and along the arteries of interstate commerce. No more has been attempted here. . . . The financial support required relates . . . to the work of the union in the realm of collective bargaining.” The conclusion to which this history clearly points is that § 2, Eleventh contemplated compulsory-unionism to force employees to share the costs of negotiating and administering collective agreements, and the costs of the adjustment and settlement of disputes. One looks in vain for any suggestion that Congress also meant in § 2, Eleventh to provide the unions with a means for forcing employees, over their objection, to support political causes which they oppose.
  III.
  The Safeguarding of Rights of Dissent.
  To the contrary, Congress incorporated safeguards in the statute to protect dissenters’ interests. Congress became concerned during the hearings and debates that the union shop might be used to abridge freedom of speech and beliefs. The original proposal for authorization of the union shop was qualified in only one respect. It provided “That no such agreement shall require such condition of employment with respect to employees to whom membership is not available upon the same terms and conditions as are generally applicable to any other member . . . .” This was primarily designed to prevejit discharge of employees for nonmembership where the union did not admit the employee to membership on racial grounds. See House Hearings, p. 68; Senate,.Hearings, pp. 22-25. But it was strenuously protested that the proposal provided no protection for an employee who disagreed with union policies or leadership. It was argued, for example, that “the right of free speech is at stake. ... A man could feel that he was no longer able freely to express himself because he could be dismissed on account of criticism of the union . . . .” House Hearings, p. 115; see also Senate Hearings, pp. 167-169, 320. Objections of this kind led the rail unions to propose an addition to the proviso to § 2, Eleventh to prevent loss of job for lack of union membership “with respect to employees to whom membership was denied or terminated for any reason other than the failure of the employee to tender the periodic dues, fees, and assessments uniformly required as a condition of acquiring or retaining membership.” House Hearings, p. 247. Mr. Harrison presented this text and stated, “It is submitted that this bill with the amendment as suggested in this statement remedies the alleged abuses of compulsory union membership as claimed by the opposing witnesses, yet makes possible the elimination of the ‘free rider’ and the sharing of the burden of maintenance by all of the beneficiaries of union activity.” House Hearings, p. 253. Mr. Harrison also sought to reassure Committee members as to the possible implications of other language of the proposed bill; he explained that “fees” meant “initiation fees,” and “assessments” was intended primarily to cover the situation of a union which had only nominal dues, so that its members paid “an assessment to finance the activities of the general negotiating committee ... it will vary month by month, based on the expenses and work of that committee.” P. 257. Or, he explained, an assessment might cover convention expenses. “So we had to use the word ‘assessment’ in addition to dues and fees because some of the unions collect a nominal amount of dues and an assessment month after month to finance part of the activities, although in total it perhaps is no different than the dues paid in the first instance which comprehended all of those expenses.” P. 258. In reporting the bill, the Senate Committee expressly noted the protective proviso, S. Rep. No. 2262, 81st Cong., 2d Sess., pp. 3-4, and affixed the Senate additional limitations. The words “not including fines and penalties” were added, to make it clear that termination of union membership for their nonpayment would not be grounds for discharge. It was also made explicit that “fees” meant “initiation fees.” See 96 Cong. Rec. 16267-16268.
  A congressional concern over possible impingements on the interests of individual dissenters from union policies is therefore discernible. It is true that opponents of the union shop urged that Congress should not allow it without explicitly regulating the amount of dues which might be exacted or prescribing the uses for which the dues might be expended. We may assume that Congress was also fully conversant with the long history of intensive involvement of the railroad unions in political activities. But it does not follow that § 2, Eleventh places no restriction on the use of an employee’s money, over his objection, to support political causes he opposes merely because Congress did not enact a comprehensive regulatory scheme governing expenditures. For it is abundantly clear that Congress did not completely abandon the policy of full freedom of choice embodied in the 1934 Act, but rather made inroads on it for the limited purpose of eliminating the problems created by the “free rider.” That policy survives in § 2, Eleventh in the safeguards intended to protect freedom of dissent. Congress was aware of the conflicting interests involved in the question of the union shop and sought to achieve their accommodation. As was said by the Presidential Emergency Board which recommended the making of the union-shop agreement involved in this case:
  “It is not as though Congress had believed it was merely removing some abstract legal barrier and not passing on the merits. It was made fully aware that it was deciding these critical issues of individual right versus collective interests which have been stressed in this proceeding.
  “Indeed, Congress gave very concrete evidence that it carefully considered the claims of the individual to be free of arbitrary or unreasonable restrictions resulting from compulsory unionism. It did not give a blanket approval to union-shop agreements. Instead it enacted a precise and carefully drawn limitation on the kind of union-shop agreements which might be made. The obvious purpose of this careful prescription was to strike a balance between the interests pressed by the unions and the considerations which the Carriers have urged. By providing that a worker should not be discharged if he was denied or if he lost his union membership for any reason other than nonpayment of dues, initiation fees or assessments, Congress definitely indicated that it had weighed carefully and given effect to the policy of the arguments against the union shop.” Report of Presidential Emergency Board No. 98, appointed pursuant to Exec. Order No. 10306, Nov. 15,1951, p. 6.
  We respect this congressional purpose when we construe § 2, Eleventh as not vesting the unions with unlimited power to spend exacted money. We are not called upon to delineate the precise limits of that power in this case. We have before us only the question whether the power is restricted to the extent of denying the unions the right, over the employee’s objection, to use his money to support political causes which he opposes. Its use to support candidates for public office, and advance political programs, is not a use which helps defray the expenses of the negotiation or administration of collective agreements, or the expenses entailed in the adjustment of grievances and disputes. In other words, it is a use which falls clearly outside the reasons advanced by the unions and accepted by Congress why authority to make union-shop agreements was justified. On the other hand, it is equally clear that it is a use to support activities within the area of dissenters’ interests which Congress enacted the proviso to protect. We give § 2, Eleventh the construction which achieves both congressional purposes when we hold, as we do, that § 2, Eleventh is to be construed to deny the unions, over an employee’s objection, the power to use his exacted funds to support political causes which he opposes.
  We express no view as to other union expenditures objected to by an employee and not made to meet the costs of negotiation and administration of collective agreements, or the adjustment and settlement of grievances and disputes. We do not understand, in view of the findings of the Georgia courts and the question decided by the Georgia Supreme Court, that there is before us the matter of expenditures for activities in the area between the costs which led directly to the complaint as to “free riders,” and the expenditures to support union political activities. We are satisfied, however, that § 2, Eleventh is to be interpreted to deny the unions the power claimed in this case. The appellant unions, in insisting that § 2, Eleventh contemplates their use of exacted funds to support political causes objected to by the employee, would have us hold that Congress sanctioned an expansion of historical practices in the political area by the rail unions. This we decline to do. Both by tradition and, from 1934 to 1951, by force of law, the rail unions did not rely upon the compulsion of union security agreements to exact money to support the political activities in which they engage. Our construction therefore involves no curtailment of the traditional political activities of the railroad unions. It means only that those unions must not support those activities, against the expressed wishes of a dissenting employee, with his exacted money.
  IV.
  The Appropriate Remedy.
  Under our view of the statute, however, the decision of the court below was erroneous and cannot stand. The appellees who have participated in this action have in the course of it made known to their respective unions their objection to the use of their money for the support of political causes. In that circumstance, the respective unions were without power to use payments thereafter tendered by them for such political causes. However, the union-shop agreement itself is not unlawful. Railway Employes’ Dept. v. Hanson, supra. The appellees therefore remain obliged, as a condition of continued employment, to make the payments to their respective unions called for by the agreement. Their right of action stems not from constitutional limitations on Congress’ power to authorize the union shop, but from § 2, Eleventh itself. In other words, appellees’ grievance stems from the spending of their funds for purposes not authorized by the Act in the face of their objection, not from the enforcement of the union-shop agreement by the mere collection of funds. If their money were used for purposes contemplated by § 2, Eleventh, the appellees would have no grievance at all. We think that an injunction restraining enforcement of the union-shop agreement is therefore plainly not a remedy appropriate to the violation of the Act’s restriction on expenditures. Restraining the collection of all funds from the appellees sweeps too broadly, since their objection is only to the uses to which some of their money is put. Moreover, restraining collection of the funds as the Georgia courts have done might well interfere with the appellant unions’ performance of those functions and duties which the Railway Labor Act places upon them to attain its goal of stability in the industry. Even though the lower court decree is subject to modification upon proof by the appellants of cessation of improper expenditures, in the interim the prohibition is absolute against the collection of all funds from anyone who can show that he is opposed to the expenditure of any of his money for political purposes which he disapproves. The complete shutoff of this source of income defeats the congressional plan to have all employees benefited share costs “in the realm of collective bargaining,” Hanson, 351 U. S., at p. 235, and threatens the basic congressional policy of the Railway Labor Act for self-adjustments between effective carrier organizations and effective labor organizations.
  Since the case must therefore be remanded to the court below for consideration of a proper remedy, we think that it is appropriate to suggest the limits within which remedial discretion may be exercised consistently with the Railway Labor Act and other relevant public policies. As indicated, an injunction against enforcement of the union shop itself through the collection of funds is unwarranted. We also think that a blanket injunction against all expenditures of funds for the disputed purposes, even one conditioned on cessation of improper expenditures, would not be a proper exercise of equitable discretion. Nor would it be proper to issue an interim or temporary blanket injunction of this character pending a final adjudication. The Norris-LaGuardia Act, 47 Stat. 70, 29 U. S. C. §§ 101-115, expresses a basic policy against the injunction of activities of labor unions. We have held that the Act does not deprive the federal courts of jurisdiction to enjoin compliance with various mandates of the Railway Labor Act. Virginian R. Co. v. System Federation, 300 U. S. 515; Graham v. Brotherhood of Locomotive Firemen & Enginemen, 338 U. S. 232. However, the policy of the Act suggests that the courts should hesitate to fix upon the injunctive remedy for breaches of duty owing under the labor laws unless that remedy alone can effectively guard the plaintiff’s right. In Graham this Court found an injunction necessary to prevent the breach of the duty of fair representation, in order that Congress might not seem to have held out to the petitioners there “an illusory right for which it was denying them a remedy.” 338 U. S., at p. 240. No such necessity for a blanket injunctive remedy because of the absence of reasonable alternatives appears here. Moreover, the fact that these expenditures are made for political activities is an additional reason for reluctance to impose such an injunctive remedy. Whatever may be the powers of Congress or the States to forbid unions altogether to make various types of political expenditures, as to which we express no opinion here, many of the expenditures involved in the present case are made for the purpose of disseminating information as to candidates and programs and publicizing the positions of the unions on them. As to such expenditures an injunction would work a restraint on the expression of political' ideas which might be offensive to the Eirst Amendment. For the majority also has an interest in stating its views without being silenced by the dissenters. To attain the appropriate reconciliation between majority and dissenting interests in the area of political expression, we think the courts in administering the Act should select remedies which protect both interests to the maximum extent possible without undue impingement of one on the other.
  Among possible remedies which would appear appropriate to the injury complained of, two may be enforced with a minimum of administrative difficulty and with little danger of encroachment on the legitimate activities or necessary functions of the unions. Any remedies, however, would properly be granted only to employees who have made known to the union officials that they do not desire their funds to be used for political causes to which they object. The safeguards of § 2, Eleventh were added for the protection of dissenters’ interest, but dissent is not to be presumed — it must affirmatively be made known to the union by the dissenting employee. The union receiving money exacted from an employee under a union-shop agreement should not in fairness be subjected to sanctions in favor of an employee who makes no complaint of the use of his money for such activities. From these considerations, it follows that the present action is not a true class action, for there is no attempt to prove the existence of a class of workers who had specifically objected to the exaction of dues for political purposes. See Hansberry v. Lee, 311 U. S. 32, 44. Thus we think that only those who have identified themselves as opposed to political uses of their funds are entitled to relief in this action.
  One remedy would be an injunction against expenditure for political causes opposed by each complaining employee of a sum, from those moneys to be spent by the union for political purposes, which is so much of the moneys exacted from him as is the proportion of the union’s total expenditures made for such political activities to the union’s total budget. The union should not be in a position to make up such sum from money paid by a nondissenter, for this would shift a disproportionate share of the costs of collective bargaining to the dissenter and have the same effect of applying his money to support such political activities. A second remedy would be restitution to each individual employee of that portion of his money which the union expended, despite his notification, for the political causes to which he had advised the union he was opposed. There should be no necessity, however, for the employee to trace his money up to and including its expenditure; if the money goes into general funds and no separate accounts of receipts and expenditures of the funds of individual employees are maintained, the portion of his money the employee would be entitled to recover would be in the same proportion that the expenditures for political purposes which he had advised the union he disapproved bore to the total union budget.
  The judgment is reversed and the case is remanded to the court below for proceedings not inconsistent with this opinion.
  Reversed and remanded.
  64 Stat. 1238, 45 U. S. C. § 152, Eleventh. The section provides:
  “Eleventh. Notwithstanding any other provisions of this chapter, or of any other statute or law of the United States, 'or Territory thereof, or of any State, any carrier or carriers as defined in this chapter and a labor organization or labor organizations duly designated and authorized to represent employees in accordance with the requirements of this chapter shall be permitted—
  “(a) .to make agreements, requiring, as a condition of continued employment, that within sixty days following the beginning of such employment, or the effective date of such agreements, whichever is the later, all employees shall become members of the labor organization representing their craft or class: Provided, That no such agreement shall require such condition of employment with respect to employees to whom membership is not available upon the same terms and conditions as are generally applicable to any other member or with respect to employees to whom membership was denied or terminated for any reason other than the failure of the employee to tender the periodic dues, initiation fees, and assessments (not including fines and penalties) uniformly required as a condition of acquiring or retaining membership.
  “(b) to make agreements providing for the deduction by such carrier or carriers from the wages of its or their employees in a craft or class and payment to the labor organization representing the craft or class of such employees, of any periodic dues, initiation fees, and assessments (not including fines and penalties) uniformly required as a condition of acquiring or retaining membership: Provided, That no such agreement shall be effective with respect to any individual employee until he shall have furnished the employer with a written assignment to the labor organization of such membership dues, initiation fees, and assessments, which shall be revocable in writing after the expiration of one year or upon the termination date of the applicable collective agreement, whichever occurs sooner.
  “(c) The requirement of membership in a labor organization in an agreement made pursuant to subparagraph (a) of this paragraph shall be satisfied, as to both a present or future employee in engine, train, yard, or hostling service, that is, an employee engaged in any of the services or capacities covered in the First Division of paragraph (h) of section 153 of this title, defining the jurisdictional scope of the First Division of the National Railroad Adjustment Board, if said employee shall hold or acquire membership in any one of the labor organizations, national in scope, organized in accordance with this chapter and admitting to membership employees of a craft or class in any of said services; and no agreement made pursuant to sub-paragraph (b) of this paragraph shall provide for deductions from his wages for periodic dues, initiation fees, or assessments payable to any labor organization other than that in which he holds membership: Provided, however, That as to an employee in any of said services on a particular carrier at the effective date of any such agreement on a carrier, who is not a member of any one of the labor organizations, national in scope, organized in accordance with this chapter and admitting to membership employees of a craft or class in any of said services, such employee, as a condition of continuing his employment, may be required to become a member of the organization representing the craft in which he is employed on the effective date of the first agreement applicable to him: Provided, further, That nothing herein or in any such agreement or agreements shall prevent an employee from changing membership from one organization to another organization admitting to membership employees of a craft or class in any of said services.
  “(d) Any provisions in paragraphs Fourth and Fifth of this section in conflict herewith are to the extent of such conflict amended.”
  The pertinent findings of the trial court are:
  “(5) The funds so exacted from plaintiffs and the class they represent by the labor union defendants have been, and are being, used in substantial amounts by the latter to support the political campaigns of candidates for the offices of President and Vice President of the United States, and for the Senate and House of Representatives of the United States, opposed by plaintiffs and the class they represent, and also to support by direct and indirect financial contributions and expenditures the political campaigns of candidates for State and local public offices, opposed by plaintiffs and the class they represent. The said funds are so used both by each of the labor union defendants separately and by all of the labor union defendants collectively and in concert among themselves and with other organizations not parties to this action through associations, leagues, or committees formed for that purpose.
  “(6) Those funds have been and are being used in substantial amounts to propagate political and economic doctrines, concepts and ideologies and to promote legislative programs opposed by plaintiffs and the class they represent. Those funds have also been and are being used in substantial amounts to impose upon plaintiffs and the class they represent, as well as upon the general public, conformity to those doctrines, concepts, ideologies and programs.
  “(7) The exaction of moneys from plaintiffs and the class they represent for the purposes and activities described above is not reasonably necessary to collective bargaining or to maintaining the existence and position of said union defendants as effective bargaining agents or to inform the employees whom said defendants represent of developments of mutual interest.
  “(8) The exaction of said money from plaintiffs and the class they represent, in the fashion set forth above by the labor union defendants, is pursuant to the union shop agreements and in accordance with the terms and conditions of those agreements.”
  The trial judge concluded:
  “Said exaction and use of money, said union shop agreements and Section 2 (eleventh) of the Railway Labor Act and their enforcement violate the United States Constitution which in the First, Fifth, Ninth and Tenth Amendments thereto guarantees to individuals protection from such unwarranted invasion of their personal and property rights, (including freedom of association, freedom of thought, freedom of speech, freedom of press, freedom to work and their political freedom and rights) under the cloak of federal authority.”
  The judgment and decree provided that the appellants and the carriers “be and they hereby are perpetually enjoined from enforcing the said union shop agreements . . . and from discharging petitioners, or any member of the class they represent, for refusing to become or remain members of, or pay periodic dues, fees, or assessments to, any of the labor union defendants, provided, however, that said defendants may at any time petition the court to dissolve said injunction upon a showing that they no longer are engaging in the improper and unlawful activities described above.” Judgment was also entered in favor of three of the named appellees for the amounts of dues, initiation fees and assessments paid by them.
  The Supreme Court of Georgia viewed the constitutional question presented for its decision as follows:
  “The fundamental constitutional question is: Does the contract between the employers of the plaintiffs and the union defendants, which compels these plaintiffs, if they continue to work for the employers, to join the unions of their respective crafts, and pay dues, fees, and assessments to the unions, where a part of the same will be used to support political and economic programs and candidates for public office, which the plaintiffs not only do not approve but oppose, violate their rights of freedom of speech and deprive them of their property without due process of law under the First and Fifth Amendments to the Federal Constitution?” 215 Ga., at 43-44, 108 S. E. 2d, at 807.
  The record contained one union constitution with a statement of political objectives and various other union constitutions authorizing political education activity, lobbying before legislative bodies, and publication of union views. There was an indication that Labor was furnished to members of some unions. There was also material taken from the hearings on § 2, Eleventh which included statements of management opponents of the Act that union dues were used for political activities and employees should not be forced to join unions if they did not like the purposes for which their funds would be spent. And there were statements by Rep. Hoffman of Michigan during the debate on the bill, warning union leaders not to levy “political assessments” and use the Act to force their members to meet those assessments.
  “[T] hese railroad labor organizations in the past have refrained from advocating the union shop agreement, or any other type of union security. It has always been our philosophy that the strongest and most militant type of labor organization was the one whose members were carefully selected and who joined conviction and a desire to assist their fellows in promoting objects of labor unionism . . . .” Statement of Charles J. MacGowan, vice president of the International Brotherhood of Boilermakers, Transcript of Proceedings, Presidential Board, appointed Feb. 20, 1943, p. 5358. See also Transcript of Proceedings, Presidential Emergency Board No. 98, appointed pursuant to Exec. Order No. 10306, Nov. 15, 1951, pp. 835-845, Carriers' Exhibit W-28. For an analysis of the reasons for the long-time absence of pressure for union security agreements in the railway industry, see Toner, The Closed Shop, pp. 93-114.
  The principle of freedom of choice had been incorporated in two earlier pieces of legislation governing railroads. The Bankruptcy Act of March 3,1933,47 Stat. 1481, § 77 (p) and (q), provided that no judge, trustee, or receiver of a carrier should interfere with employee organization, influence or coerce employees to join a company union, or require employees to join or refrain from joining a labor organization. The Emergency Railroad Transportation Act of June 16, 1933, 48 Stat. 214, § 7 (e), required all carriers to abide by these provisions of the Bankruptcy Act. The latter provision was temporary, with a maximum duration of two years. See testimony of Joseph B. Eastman, Federal Coordinator of Transportation, House Hearings on H. R. 7650, 73d Cong., 2d Sess., pp. 22-23, and his official interpretation of this legislation, 7 Interstate Commerce Acts Ann., 1934 Supp., pp. 5972-5973.
  Eastman further emphasized that only the Trainmen were immediately affected by the broader prohibition he supported. “I am confident that the only real support for the proposed amendments is from a single organization. None of the other standard organizations has anything to gain from such changes in the bill.” Eastman letter, supra, p. 16. For other expressions of Eastman’s views, see House Hearings, supra, pp. 28-29; Hearings on H. R. 9861, House Rules Committee, 73d Cong., 2d Sess., pp. 22-24. That other rail unions were still committed at this time to the principle of voluntarism, despite their support of the Trainmen’s position, is indicated by the statement of George H. Harrison, representing the Railway Labor Executives’ Association: “Now, I hope the committee will not get the thought from these statements that the railroad labor unions that I speak for want to force these men into our unions, because that is not our purpose; . . . .” House Hearings on H. R. 7650, supra, p. 86.
  The Board’s view as to the illegality of a union shop was supported by an opinion of the Attorney General, 40 Op. Atty. Gen., No. 59, p. 254 (Dec. 29, 1942).
  At the time of the congressional deliberations which preceded the enactment of the Labor Management Relations Act, 1947, the Trainmen, through their president, A. F. Whitney, advocated the closed shop, and urged the repeal of the provisions which prohibited it. Hearings on Amendments to the National Labor Relations Act, House Committee on Education and Labor, 80th Cong., 1st Sess., pp. 1549-1552, 1561. However, the Railway Labor Executives' Association opposed amendment of the 1934 Act. A. E. Lyon, executive secretary of the Association, said: “We want to make it very clear that we are proposing no amendments to the Railway Labor Act. We believe that none is necessary, and we are opposed to those which Mr. Whitney suggested.” Hearings, p. 3722. Lyon added: “We are not asking you to amend the Railway Labor Act and provide a closed shop as Mr. Whitney did. We do not think it is necessary.” P. 3724. In response to the query, “By the services you have performed for your members you have attracted people voluntarily to join. Is that not correct?” Lyon replied: “I think that is true. And many of our union people believe they would rather have members that belong because they want to, rather than because they have to.” P. 3732.
  The Act of 1888, 25 Stat. 501, authorized the creation of boards of voluntary arbitration to settle controversies between carriers and their employees which threatened to disrupt transportation. § 1. The Act also provided for a temporary presidential commission to investigate the causes of a controversy and the best means of adjusting it; the commission was to report the results of its investigation to the President and Congress. § 6.
  In 1898 Congress repealed the Act of 1888 and passed the Erdman Act, 30 Stat. 424, providing that “whenever a controversy concerning wages, hours of labor, or conditions of employment shall arise between a carrier subject to this Act and the employees of such carrier, seriously interrupting or threatening to interrupt the business of said carrier,” the Chairman of the Interstate Commerce Commission and the Commissioner of Labor should attempt to resolve the dispute, at the request of either party, by conciliation and mediation. § 2. If these methods failed, a board of voluntary arbitration could be set up with representatives on it of the carrier and the “labor organization to which the employees directly interested belong . . . § 3. Section 10 of the Act also made it criminal for an employer to require an employee to promise not to become or remain a member of a labor organization or to discriminate against an employee for such membership, a provision which was held unconstitutional in Adair v. United States, 208 U. S. 161.
  The Erdman Act was superseded in 1913 by the passage of the Newlands Act, 38 Stat. 103. It created a Board of Mediation and Conciliation to which either party to a controversy could refer the dispute and which could proffer its services even without request if an interruption of traffic was imminent and seriously jeopardized the public interest. The Board also was authorized to give opinions as to the meaning or application of agreements reached through mediation. § 2. The arbitration procedures set up by the Erdman Act were further elaborated. §§ 3-8.
  In 1916 Congress imposed the 8-hour day on the railroads, 39 Stat. 721. During the period of federal operation of the railroads in World War I and afterwards the Federal Government executed agreements with many of the national labor organizations as representatives of the railroad employees. Boards of adjustment were also set up to handle disputes concerning the interpretation and application of agreements. See Hearings on S. 3295, Subcommittee of Senate Committee on Labor and Public Welfare, 81st Cong., 2d Sess., pp. 216, 305. By the Transportation Act of 1920, 41 Stat. 456, Congress terminated federal control and established an extensive new regulatory scheme. See n. 12, infra. See generally Hearings on S. 3463, Subcommittee of the Senate Committee on Labor and Public Welfare, 81st Cong., 2d Sess., pp. 124-131.
  The Transportation Act of 1920 provided for a Railroad Labor Board, with power to render a decision in disputes between carriers and their employees over wages, grievances, rules, or working conditions not resolved through conference and adjustment procedures. § 307. In rendering a decision on wages or working conditions, the Board had a duty to establish wages and conditions which in its opinion were “just and reasonable.” § 307 (d). It was held, however, that the decisions of the Board could not be enforced by legal process. See Pennsylvania R. Co. v. United States Railroad Labor Board, 261 U. S. 72; Pennsylvania R. System v. Pennsylvania R. Co., 267 U. S. 203. By 1926 the Board had lost the confidence of both the unions and many of the railroads. Commented the Senate Committee which considered the Railway Labor Act, of 1926: “In view of the fact that the employees absolutely refuse to appear before the labor board and that many of the important railroads are themselves opposed to it, that it has been held by the Supreme Court to have no power to enforce its judgments, that its authority is not recognized or respected by the employees and by a number of important railroads, that the President has suggested that it would be wise to seek a substitute for it, and that the party platforms of both the Republican and Democratic Parties in 1924 clearly indicated dissatisfaction with the provisions of the transportation act relating to labor, the committee concluded that the time had arrived when the labor board should be abolished and the provisions relating to labor in the transportation act, 1920, should be repealed.” S. Rep. No. 606, 69th Cong., 1st Sess.; pp. 3-4.
  For reiteration by various union spokesmen of this purpose of eliminating the problems created by the “free rider,” see Hearings on S. 3296, supra, pp. 6, 32-33, 36, 40, 66, 130, 236-237; Hearings on H. R. 7789, supra, pp. 9, 19, 25-26, 29, 37-38, 49-50, 79, 81, 85, 87, 89, 228, 240-241, 250, 253, 255, 275. For other statements by members of Congress indicating their- acceptance of this justification for the legislation, see Senate Hearings, supra, pp. 169-171; House Hearings, supra, pp. 25, 87,106,110,139; 96 Cong. Rec. 16279,17050-17051, 17055, 17057, 17058.
  Mr. Harrison expressly disclaimed that the union shop was sought in order to strengthen the bargaining power of the unions. He said:
  “I do not think it would affect the power of bargaining one way or the other .... If I get a majority of the employees to vote for my union as the bargaining agent, I have got as much economic power at that stage of development as I will ever have. The man that is going to scab — he will scab whether he is in or out of the union, and it does not make any difference.” House Hearings, supra, pp. 20-21.
  Nor was any claim seriously advanced that the union shop was necessary to hold or increase union membership. The prohibition against union security in the 1934 Act had not interfered with the growth of union membership or caused the unions to lose their positions as exclusive bargaining agents. See A. F. of L. v. American Sash Co., 335 U. S. 538, 548-549, n. 4 (concurring opinion); see also Transcript of Proceedings, Presidential Emergency Board No. 98, appointed pursuant to Exec. Order No. 10306, Nov. 15,1951, Carriers’ Exhibits W-23, W-28, pp. 38-51.
  The unions continued to urge the elimination of the problems created by the “free rider” as the justification for the union shop in the proceedings before the Presidential Emergency Board, which recommended that the carriers make the agreements involved in this case. Mr. Harrison said: “. . . the railroad unions’ primary purpose in seeking and obtaining the amendment to the Railway Labor Act in 1951 to permit the check-off for payment of dues, was to eliminate the ‘free rider,’ the guy who drags his feet, a term which is applied by unions to non-members who obtain, without cost to themselves, the benefits of collective bargaining procured through the efforts of the dues-paying members.” Transcript of Proceedings, Presidential Emergency Board No. 98, appointed pursuant to Exec. Order No. 10306, Nov. 15, 1951, p. 150. See also Transcript, pp. 40-44, 144-156, 182-183, 186-188, 202-203, 268, 283-286, 289, 545, 608-611, 1893, 1901, 2136, 2495-2497, 2795, 2839, 2930, 3014-3015, 3018-3019.
  Section 2, Eleventh (c), which gives scope for intercraft mobility in the rail industry, is consistent with the view that the primary union and congressional concern was with the elimination of the “free rider” who did not support his representative’s performance of its functions under the Act. The section provides that an operating employee cannot be required to become a member of his craft or class representative if “said employee shall hold or acquire membership in any one of the labor organizations, national in scope, organized in accordance with this chapter and admitting to membership employees of a craft or class in any of said services . . . .” This Court held in Pennsylvania R. Co. v. Rychlik, 352 U. S. 480, that the unions “national in scope” contemplated by this provision are those which have already qualified as electors under § 3 of the Act to participate in the National Railroad Adjustment Board. As the court said in Pigott v. Detroit, T. & I. R. Co., 116 F. Supp. 949, 955, n. 11, aff’d, 221 F. 2d 736: “Each union participating in the agencies of the Act must itself pay for the salaries and expenses of its officials who serve in such agencies. This constitutes a considerable financial burden which must be reflected in the dues charged the employees. Unless a labor organization were obliged to participate in the judgment board machinery before it could qualify for the union shop exception, it would place the bargaining representative in an unfair competitive position with respect to a rival union. Employees would be tempted to desert the organization of a bargaining representative which was assuming its responsibilities under the Act in favor of another union which was not contributing to its operation and which could thereby offer cheaper dues. This would defeat the very purpose of the union amendment which is to compel each employee to contribute his part to the bargaining representative’s activities on his behalf, including its participation in the administrative machinery of the Act.”
  See Senate Hearings, pp. 173-174, 316-317; House Hearings, pp. 160, 172-173. See also 96 Cong. Rec. 17049-17050.
  A distinction between the use of union funds for political purposes and their expenditure for nonpolitical purposes is implicit in other congressional enactments. Thus the Treasury has adopted this regulation under § 162 of the Internal Revenue Code of 1954 to govern the deductibility for income-tax purposes of payments by union members to their union:
  “Dues and other payments to an organization, such as a labor union or a trade association, which otherwise meet the requirements of the regulations under section 162, are deductible in full unless a substantial part of the organization’s activities consists of [expenditures for lobbying purposes, for the promotion or defeat of legislation, for political campaign purposes (including the support of or opposition to any candidate for public office), or for carrying on propaganda (including advertising) related to any of the . foregoing purposes] .... If a substantial part of the activities of the organization consists of one or more of those specified, deduction will be allowed only for such • portion of such dues and other payments as the taxpayer can clearly establish is attributable to activities other than those so specified. The determination as to whether such specified activities constitute a substantial part of an organization’s activities shall be based on all the facts and circumstances. In no event shall special assessments or similar payments (including an increase in dues) made to any organization for any of such specified purposes be deductible.” 26 CFR § 1.162-15 (e) (2); see also Rev. Proc. 61-10, 1961-16 Int. Rev. Bull. 49, April 17, 1961. Cf. Cammarano v. United States, 358 U. S. 498.
  For example, many of the national labor unions maintain death benefit funds from the dues of individual members transmitted by the locals.
  In 1958 Senator Potter proposed an amendment to pending labor legislation that would have given employees subject to a union-shop agreement the right to have their dues used only for collective bargaining and related purposes and would have required the Secretary of Labor, if he determined that the dues were not so expended, to bring an action in behalf of the dissenter for the recovery of all the money paid by the dissenter to the union during the life of the agreement and for such other appropriate and injunctive relief as the court deemed just and proper. See 104 Cong. Rec. 11330. Senator Potter advanced this proposal to implement principles which he believed to be already implicit in the labor laws. He said, “I know that when Congress enacted legislation providing for labor and management to enter into contracts for union shops it was intended, under the union shop principle, that labor would use the dues for collective-bargaining purposes.” 104 Cong. Rec. 11215; see also id., p. 11331. The failure of the amendment to be adopted reflected disagreement in the Senate over the scope of its coverage and doubts as to the propriety of the breadth of the remedy. See 104 Cong. Rec. 11214-11224, 11330-11347.
  Compare Senator Kennedy’s objection to the remedy for recovery of all dues contemplated by the Potter amendment. 104 Cong. Rec. 11346.
  No contention was made below or here that any of the expenditures involved in this case were made in violation of the Federal Corrupt Practices Act, 18 U. S. C. § 610, or any state corrupt practices legislation.
  We note that the Labor-Management Reporting and Disclosure Act of 1959 requires every labor organization subject to the federal labor laws to file annually with the Secretary of Labor a financial report as to certain specified disbursements and also “other disbursements made by it including the purposes thereof . .. .” § 201 (b) (6). Each union is also required to maintain records in sufficient detail to supply the necessary basic information and data from which the report may be verified. § 206. The information required to be contained in such report must be available to all union members. §201 (c).
