delivered the opinion of the Court.

By the terms of an agreement (the Agreement) authorized by § 2 Eleventh of the Railway Labor Act1 between *116the Southern Railway Company and a number of railway labor organizations including the two petitioners herein, employees of Southern are obligated, as a condition of employment, to pay the periodic dues, initiation fees and assessments uniformly required as a condition of acquiring or retaining membership in the union representing their particular class or craft.2 The individual respondents herein are a number of- such employees belonging to classes or crafts represented by petitioners.3 When the Agreement was adopted respondents were not union members. They refused to pay petitioners any part of the moneys required under the- Agreement, instead bringing this action in the Superior Court of Mecklenburg County, North Carolina, to restrain its. enforcement.4 After a *117trial the Superior Court granted an injunction upon the jury’s separate findings that moneys exacted under the Agreement were used by petitioners for purposes- not reasonably necessary or related to collective bargaining, namely; (1) to support or oppose legislation, (2) to influence votes in elections for public office, (3) to make campaign contributions in such elections, (4) to support the death-benefits system operated by petitioner Brotherhood of Railway Clerks. The injunction restrained petitioners “from placing any compulsion of any nature upon the [respondents] . . . whereby they . . . against their free will and choice would be required to join the Defendant Unions ... or pay money to said Unions.” It was provided, however, that upon a. showing by petitioners of the proportion of expenditures from exacted funds that was reasonably necessary and related to collective bargaining, the injunction would be modified appropriately.

On appeal, the Supreme Court of North Carolina reversed, Allen v. Southern R. Co., 249 N. C. 491, 107 S. E. 2d 125, holding that judgment for petitioners was required by our decision in Railway Employes’ Dept. v. Hanson, 351 U. S. 225, where we held that § 2 Eleventh was a valid exercise by Congress of its powers -under the *118Commerce Clause and did not violate the First Amendment or the Due Process Clause of the Fifth. However, rehearing was granted, and pending decision thereon we decided International Assn. of Machinists v. Street, 367 U. S. 740. Upon reconsideration of the Superior Court’s judgment in the light of that decision, the Supreme Court of North Carolina divided equally, which had the effect of affirming the lower court’s judgment. 256 N. C. 700, 124 S. E. 2d 871 (per curiam); see Schoenith v Town & Country Realty Co., 244 N. C. 601, 94 S. E. 2d 592 (per curiam); Ward v. Odell Mfg. Co., 126 N. C. 946, 36 S. E. 194. We granted certiorari, 371 U. S. 875, to consider whether the injunction granted by the Superior Court might stand consistently with our decision in Street. We reverse and remand for further proceedings not inconsistent with this opinion.

First. We held in Street “that § 2, Eleventh is to be ' construed to deny the unions, oyer an employee’s objection, the power to use his exacted funds to support political causes which he opposes.” 367 U. S., at 768-769. Respondents’ amended complaint alleges that sums exacted under the Agreement “have been and are and will be regularly and continually used by the defendant Unions to carry on, finance and pay for political activities directly at cross-purposes with the free will and choice of the plaintiffs.” This allegation sufficiently states a cause of action. It would be impracticable to require a dissenting employee to allege and prove each distinct union political expenditure to which he objects; it is enough that he manifests his opposition to any political expenditures by the union.5 But we made clear in Street *119that “dissent is not to be presumed — it must affirmatively be made known to the union by the dissenting employee.” 367 U. S., at 774.6 At trial, only 14 of the respondents testified that they objected to the use of exacted sums for political causes. No respondent who does not in ■ the course of the further proceedings in this case prove that he objects to such use will be entitled to relief. This is not and cannot be a class action. See note 4, supra. “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.” 367 U. S., at 774.

Second. We also held in Street that an injunction relieving dissenting employees of all obligation to pay the moneys due under an agreement authorized by § 2 Eleventh was impermissible. Such employees “remain obliged, as á condition of continued employment, to make *120the payments to their respective unions called for by the agreement. Their . . . 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.” 367 U. S., at 771. The injunction granted by the Superior Court was thus improper, even though it is subject to modification if petitioners come forward and prove the proportion of exacted funds required for purposes germane to collective bargaining. Even such a remedy, we' think, “sweeps too broadly . . . [and] might well interfere with the . . . unions' performance of those functions and duties which the Railway Labor Act places upon them to attain its goal of stability in the industry.” Ibid.

It also follows from Street that the Superior Court erred in granting respondents interim relief against compliance with the financial obligations imposed by the Agreement.As a result of this relief none of the. respondents has taken any steps toward compliance since the suit was instituted. We think that lest the important fúnctions of labor organizations under the Railway Labor Act be unduly impaired, dissenting employees (at least in the absence of special circumstances not shown here) can be entitled to no relief until final judgment in their favor is entered. Therefore, on remand respondents should be given a reasonable time within which they must pay to the bargaining representative of their class or craft all sums required under the Agreement, including arrears, that are owing; as to any respondent failing to do this, the action must be dismissed.

Third. We suggested in Street that among the permissible remedies for dissenting employees were “an injunction against éxpenditure for political causes opposed by each complaining employee of a sum, from those *121moneys 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,” and restitution of such a sum already exacted from the complainant and expended by the union over his objection. 367 U. S., at 774-775. The necessary predicate for. such remedies is a division of the union’s political expenditures from those germane to collective bargaining, since only the former, to the extent made from exacted funds of dissenters, are not authorized by §-2 Eleventh. But at trial. no evidence was offered by either side, nor was the jury required to make findings, as to the total amount of union expenditures for political purposes, the breakdown of the total union budget according to particular kinds of expenditure, or the proportion of political expenditures in the total union budget of a given period.7 On remand, in order to frame a decree embodying the suggested remedies, two determinations will have to be made: (1) what expenditures disclosed by the récord are political; (2) what percentage of total union expenditures are political expenditures. As to (1) we presently intimate no view, see note 7, infra, because here, as in Street, see 367 U. S., at 768-770, the courts below made no attempt to draw the boundary between political expenditures and those germane to collective bargaining, and it would be inappropriate for this Court to do so in the first instance and upon the present record. As to (2) the present record is insufficient to enable any calculation.

*122Since the unions possess the facts and records from which the proportion of political to total union expenditures can reasonably be calculated, basic considerations of fairness compel that they, not the individual employees, bear the burden of proving such proportion. Absolute precision in the calculation of such proportion is not, of course, to be expected or required; we are mindful of the difficult accounting problems that may arise. And no decree would be proper which appeared likely to infringe the unions’ right to expend. uniform exactions under the union-shop agreement in support of activities germane to collective bargaining and, as well, to expend nondissenters’ such exactions in support of political activities.

Fourth. While adhering to the principles governing remedy which we announced in Street, see 367 U. S., at 771-775, we think it appropriate to suggest, in addition, a practical decree to which each respondent proving his right to relief would be entitled. Such, a decree would order (1) the refund to him of a portion of the exacted funds in the same proportion that union political expenditures bear to total union expenditures, and (2) a reduction of future such exactions from him by the same proportion. We recognize that practical difficulties may attend a decree reducing an employee’s obligations under the union-shop agreement by a fixed proportion, since the proportion of the union budget devoted to political activities may not be constant. The difficulties in judicially administered relief, although not insurmountable (a decree once entered would of course be modifiable upon a showing of changed circumstances), should, we think, encourage petitioner unions to consider the adoption by their membership of some voluntary plan by which dissenters would be afforded an internal' union remedy. *123There is precedent for such a plan.8 If a union- agreed upon a formula for ascertaining the proportion bf political expenditures in its budget, and made available a simple procedure for allowing dissenters to be excused from having to pay this proportion of moneys due from them under the union-shop agreement, prolonged and expensive litigation might well be averted. The instant action, for example, has been before the courts for 10 years and has not yet run its course. It is a lesson of our national history of industrial relations that resort to litigation to settle the rights of labor organizations and employees very *124often proves unsatisfactory. The courts will not shrink from affording what remedies they may, with due regard for the legitimate interests of all parties; but it is appropriate to remind the parties of the availability of more practical alternatives to litigation for the vindication of the rights and accommodation of interests here involved.

Reversed and remanded.

APPENDIX TO OPINION OF THE COURT.

The Trade Union Act of 1913, 2 & 3 Geo. V, c. 30, reads in part as follows:

3. — (1) The funds of a trade union shall not be applied, either directly or in conjunction with any other trade union, association, or body, or otherwise indirectly, in the furtherance of the political objects to which this section applies (without prejudice to the furtherance of any other political objects), unless the furtherance of those objects has been approved as an object of the union by a resolution for the time being in force passed on a ballot of the members of the union taken in accordance with this Act for the purpose by a majority of the members *125voting; and where such a resolution is in force, unless rules, to be approved, whether the union is registered or not, by the Registrar of Friendly Societies, are in force providing—

•(a) That any payments in the furtherance of. those objects are to be made out of a separate fund (in this Act referred to as the political fund of the union), and for the exemption in accordance with this Act of ahy member of the union from any obligation to contribute to such a fund if he gives notice in accordance with this Act that he objects to contribute; and

(6) That a member who is exempt from the obligation to contribute to the political fund of the union shall not be excluded from any benefits of the union, or placed in any respect either directly or indirectly under any disability or at any disadvantage as compared with other members of the union (except in relation to the control or management of the political fund) by reason of his being so exempt, and that contribution to the political fund of the union shall not be made a condition for admission to the' union.

(2) If any member of a trade union alleges that he is aggrieved by a breach of any rule made in pursuance of this section, he may complain to the Registrar of Friendly Societies, and the Registrar of Friendly Societies, after giving the complainant and any representative of the union an opportunity of being heard, may, if he considers that such a'breach has been committed, make such order for remedying the breach as he thinks just under the circumstances; and any such order of the Registrar shall be binding and conclusive on all parties without appeal and shall not be removable into any court of law or restrainable by injunction, and on *126being recorded in the county court, may be enforced as if it had been an order of the county court. . . .

(3) The political objects to which this section applies are the expenditure of money—

(а) on the payment of any expenses incurred either directly or indirectly by a candidate or prospective candidate for election to Parliament or to any public office, before, during, or after the election in connexion with his candidature or election; or

(б) on the holding of any meeting or the distribution of any literature or documents in support of any such candidate or prospective candidate; or

(c) on the maintenance of any person who is a member of Parliament or who holds a public office; or

.(d) in connection with the registration of electors or the selection of a candidate, for Parliament or any public office; or

(e) on the holding of political meetings of any kind, or on the distribution of political literature or political documents of any kind, unless the main purpose of the meetings or of the distribution of the literature or documents is the furtherance of statutory objects within the meaning of this Act.

The expression “public office” in this section means the office of member of any county, county borough, district, or parish council, or board of guardians, of of any public body who have power to raise money, either directly or indirectly, by means of a rate.

(4) A resolution under this section approving political objects as an object of the union shall take effect as if it were a r.ule of the union and may be rescinded in the-sarr e manner and subject to the same provisions as such a ruia.

(5) The' provisions of this Act as to the application of the funds of a union for political purposes shall app - *127to a union which is in whole or in part an association or combination of other unions as if the individual members of the component unions were the members of that union and not the unions; but nothing in this Act shall prevent any such component union from collecting from any of their members who are not exempt on behalf of the association or combination any contributions to the political fund of the association or combination.

4. — (1) A ballot for the purposes of this Act shall be taken in accordance with rules of the union to be approved for the purpose, whether the union is registered or not, by the Registrar of Friendly Societies, but the Registrar of Friendly Societies shall not approve any such rules unless he is satisfied that every member has an equal right, and, if reasonably possible, a fair opportunity of voting, and that the secrecy of the ballot is properly secured.

(2) If the Registrar of Friendly Societies is satisfied, and certifies, that rules for the purpose of a ballot under this Act or rules made for other purposes of this Act which require approval by the Registrar, have been approved by a majority of members of a trade union, whether registered or not, voting for the purpose, or by a majority of delegates of such a trade union voting at a meeting called for the purpose, those rules shall have effect as rules of the union, notwithstanding that the provisions of the rules of the union as to the alteration of rules or the making of new rules have not been complied with.

5. — (1) A member of a trade union may . at any time give notice, in the form set out in the Schedule to this Act or in a form to the like effect, that he objects to contribute to the political fund of the union, and, on the adoption of a resolution of the union approving the furtherance of political objects as an .object of the union, notice shall be given to the members of the union ac*128quainting them-that each member has a right to be exempt from contributing to the political fund of the union, and that a form of exemption notice can be obtained by or on behalf of a member either by application at or by post' from the head office or any branch office of the union or the office of the Registrar of Friendly Societies.

Any such notice to members of the union shall be given in accordance with rules of the union approved for the purpose by the Registrar of Friendly Societies, having regard in each case to the existing practice and to the character of the union.

(2) On giving notice in accordance with this Act of his objection to contribute, a member of the union shall be exempt, so long as his notice is not withdrawn, from contributing to the political fund of the union as from the first day of January next after the notice is given, or, in the case of a notice given within one month after the. notice given to members under'this Section on the adoption of a resolution approving the furtherance of political objects, as from the date on which the member’s notice is given.

6. Effect may be given to the exemption of members to contribute to the political fund of a union either by a separate levy of contributions to that fund from the members of the union who are not exempt, and in that case the rules shall provide that no moneys of the union other than the amount raised by such separate levy shall be carried to that fund, or by relieving any members who are exempt from the payment of the whole or any part of any periodical contributions required from the members of the union towards the expenses of the union, and in that case the rules shall provide that the relief shall be given as far as possible to all members who are exempt on the occasion of the same periodical payment and for enabling each member of the union to know as respects *129any such periodical contribution, what portion, if any, of the sum payable by him is a contribution to the political fund of the union.

Address

day of 19

concurring in part and dissenting in part.

I agree with the reversal of the. interim and qualified permanent relief that was granted by the state .courts respecting the obligation to pay unión dues. But I disagree with what in effect amounts to an affirmance of the sítate judgment in other respects. I believe that dismissal of this action in its entirety is called for.

International Assn. of Machinists v. Street, 367 U. S. 740, decided only two years ago, stated in unmistakable terms that a plaintiff claiming relief in an action of this kind must show two things: (1) that he had made known *130to the union the particular political candidates or causes for whose support he did not wish his union dues used ; (2) that membership dues had been - used for such purposes.

The statement of these principles was reinforced on the' very same day in Lathrop v. Donohue, 367 U. S. 820, the Wisconsin integrated bar case, where a plurality of the Court said (at 845-846):

“Even if the demurrer is taken as admitting all the factual allegations of the complaint, even if these allegations are construed most expansively, and even if, like the Wisconsin Supreme Court, we take judicial notice of the political activities of the State Bar, still we think that the issue of impingement upon rights of free speéch'through'thé use of exacted dues is no more concretely presented for adjudication than it was in Hanson [351 U. S. 225]. Compare International Association of Machinists v. Street, ante, p. 740, at pp. 747-749. Nowhere are we clearly apprised as to the views of the appellant on any particular legislative issues on which the State Bar has taken a position, or as to the way in which and the degree to which funds compulsorily exacted from its members are used to support the organization’s political activities.” See also what follows at pp. 846-848.

These requirements have not been met in this case. At best all that has been alleged or proved is that the union will expend a part of each respondent’s still-unpaid membership dues for so-called political or other purposes not connected with collective bargaining, and'that each respondent would object to the use of any part of his dues for matters other than those relating to collective bargaining. • None of the respondents who testified could specify any particular expenditure, or even class of expenditure, to which he objected.

*131I do not understand how, consistently with Street, the Court can now hold that “it is enough that ... [a union member] manifests his opposition to any political expenditures by the union” (ante, p. 118), or how'it can say that in so holding “we are not inconsistent with” what the plurality was at such pains to point out in Lathrop (albeit in a constitutional context), id., note 5. The truth of -the. matter is that the Court has departed from the strict substantive limitations of Street and has given them (and, as I see it, also that case’s remedial limitations, compare 367 U. S., at 772-775, 778-779, 779-780, 796-797, with ante, p. 122-123 and Appendix) an expansive thrust which can hardly fail to increase the volume of this, sort of litigation- in the future.

Believing that our decisions should have more lasting power than has been accorded Street, I must respectfully dissent. I would reverse the judgment and remand the case for dismissal of the complaint.
