Justice Marshall
delivered the opinion of the Court with respect to Parts I, II, and IV, and delivered an opinion with respect to Part III, in which Justice Brennan, Justice White, and Justice Stevens joined.
In this case we consider whether provisions of the Federal Election Campaign Act of 1971, 86 Stat. 11, as amended, 2 U. S. C. § 431 et seq. (1976 ed. and Supp. III), limiting the amount an unincorporated association may contribute to a multicandidate political committee violate the First Amendment or the equal protection component of the Fifth Amendment. Concluding that these contribution limits are constitutional, we affirm the judgment of the Court of Appeals for the Ninth Circuit.
I
The California Medical Association (CMA) is a not-for-profit unincorporated association of approximately 25,000 doctors residing in California. In 1976, CMA formed the California Medical Political Action Committee (CALPAC). CALPAC is registered as a political committee with the Federal Election Commission, and is subject to the provisions of the Federal Election Campaign Act relating to multicandi-date political committees. One such provision, 2 TJ. S. C. § 441a (a) (1) (C), prohibits individuals and unincorporated associations such as CMA from contributing more than $5,000 per calendar year to any multicandidate political committee such as CALPAC. A related provision of the Act, 2 U. S. C. §441a(f), makes it unlawful for political committees such as CALPAC knowingly to accept contributions exceeding this limit.
In October 1978, the Federal Election Commission found “reason to believe” that CMA had violated the Act by making annual contributions to CALPAC in excess of $5,000, and that CALPAC had unlawfully accepted such contributions. When informal conciliation efforts failed, the Commission in April 1979 authorized its staff to institute a civil enforcement action against CMA and CALPAC to secure compliance with the contribution limitations of the Act. In early May 1979, after receiving formal notification of the Commission’s impending enforcement action, CMA and CALPAC, together with two individual members of these organizations, filed this declaratory judgment action in the United States District Court for the Northern District of California challenging the constitutionality of the statutory contribution limitations upon which the Commission’s enforcement action was to be based. Several weeks later, the Commission filed its enforcement action in the same District Court. In this second suit, CMA and CALPAC pleaded as affirmative defenses the same constitutional claims raised in their declaratory judgment action.
On May 17, 1979, pursuant to the special expedited review provisions of the Act set forth in 2 U. S. C. § 437h (1976 ed. and Supp. III), the District Court certified the constitutional questions raised in appellants’ declaratory judgment action to the Court of Appeals for the Ninth Circuit. In the meantime, pretrial discovery and preparation in the Commission’s enforcement action continued in the District Court. In May 1980, a divided Court of Appeals, sitting en banc, rejected appellants’ constitutional claims and upheld the $5,000 limit on annual contributions by unincorporated associations to multicandidate political committees. 641 F. 2d 619. Appellants sought review of that determination in this Court, again pursuant to the special jurisdictional provisions of 2 U. S. C. § 437h (1976 ed. and Supp. III). The Commission subsequently moved to dismiss the appeal, and we postponed a ruling on our jurisdiction over this case pending a hearing on the merits. 449 U. S. 817 (1980).
II
Because the Commission vigorously contends that this Court does not have jurisdiction over this appeal, we first consider the complex judicial review provisions of the Federal Election Campaign Act. The Act provides two routes by which questions involving its constitutionality may reach this Court. First, such questions may arise in the course of an enforcement proceeding brought by the Commission under 2 U. S. C. § 437g (1976 ed. and Supp. III). Such actions are filed by the Commission in the federal district courts, where they are to be accorded expedited treatment. §§437g(a) (6)(A) and (10) (1976 ed., Supp. III). The judgments of the district courts in such cases are appealable to the courts of appeals, with final review in this Court available upon certiorari or certification. § 437g (a)(9).
However, because Congress was concerned that its extensive amendments to the Act in 1974 might raise important constitutional questions requiring quick resolution, it provided an alternative method for obtaining expedited review of constitutional challenges to the Act. This procedure, outlined in 2 U. S. C. § 437h (1976 ed. and Supp. III), provides in part:
“The Commission, the national committee of any political party, or any individual eligible to vote in any election for the office of President may institute such actions in the appropriate district court of the United States, including actions for declaratory judgment, as may be appropriate to construe the constitutionality of any provision of this Act. The district court immediately shall certify all questions of constitutionality of this Act to the United States court of appeals for the circuit involved, which shall hear the matter sitting en banc.” § 437h (a).
The statute further provides that decisions of the courts of appeals on such certified questions may be reviewed in this Court on direct appeal, § 437h (b), and it directs both the courts of appeals and this Court to expedite the disposition of such cases, § 437h (c).
Although Congress thus established two avenues for judicial review of constitutional questions arising under the Act, it failed to provide any mechanism for coordinating cases in which the same constitutional issues are raised by the same parties in both a § 437h declaratory judgment action and a § 437g enforcement proceeding. The Commission contends that this legislative oversight has allowed litigants, like appellants here, to disrupt and delay enforcement proceedings brought by the Commission under § 437g by instituting separate § 437h declaratory judgment actions in which the constitutional defenses to enforcement are asserted as affirmative claims. The Commission further argues that § 437h declaratory judgment actions may seriously undermine the functioning of the federal courts because of the special treatment that these courts are required to accord such cases. To alleviate these potential problems, the Commission urges this Court to construe the overlapping judicial review provisions of the Act narrowly so as to preclude the use of § 437h actions to litigate constitutional challenges to the Act that have been or might be raised as defenses to ongoing or contemplated Commission enforcement proceedings. Under this proposed reading of § 437g and § 437h, the District Court in this case should have declined to certify appellants’ constitutional claims to the Court of Appeals in light of the Commission’s pending enforcement action against CMA and CALPAC. On this basis, we are urged by the Commission to dismiss the appeal in this case for want of jurisdiction.
Although we agree with the Commission that the judicial review provisions of the Act are scarcely a blueprint for efficient litigation, we decline to construe § 437h in the manner suggested by the Commission. There is no suggestion in the language or legislative history of § 437h indicating that Congress intended to limit the use of this provision to situations in which no § 437g enforcement proceedings are contemplated or underway. Section 437h expressly requires a district court to “immediately . . . certify all questions of the constitutionality of this Act” to the court of appeals. (Emphasis supplied.) We do not believe that Congress would have used such all-encompassing language had it intended to restrict § 437h in the manner proposed by the Commission. Indeed, the cramped construction of the statute proposed by the Commission would directly undermine the very purpose of Congress in enacting § 437h. It is undisputed that this provision was included in the 1974 Amendments to the Act to provide a mechanism for the rapid resolution of constitutional challenges to the Act. These questions may arise regardless of whether a Commission enforcement proceeding is contemplated. Yet under the Commission’s approach, even the most fundamental and meritorious constitutional challenge to the Act could not be reviewed pursuant to § 437h, but instead could be considered only pur-, suant to the more limited procedure set forth in § 437g, if this question also happened to be raised in a Commission enforcement action. If Congress had intended to remove a whole category of constitutional challenges from the purview of ’§ 437h, thereby significantly limiting the usefulness of that provision, it surely would have made such a limitation explicit.
In addition, the language of § 437g itself undercuts the Commission’s contention that § 437h actions must be held in abeyance if the same parties are or may be involved in § 437g enforcement actions brought by the Commission. The statute expressly provides that § 437g enforcement actions filed by the Commission in the district court are to be “put ahead of all other actions (other than other actions brought under this subsection or under section 437h of this title).” § 437g (a) (10) (emphasis added). If Congress had intended to coordinate § 437g and § 437h in the manner now proposed by the Commission, it is inconceivable that it would have chosen the above language. Instead, the wording of the statute plainly implies that actions brought under both sections may proceed in the district court at the same time. See Bread Political Action Committee v. Federal Election Comm’n, 591 F. 2d 29, 33 (CA7 1979), appeal pending, No. 80-1481. In sum, although Congress might have been wiser to orchestrate § 437g and § 437h in the manner proposed by the Commission, the statutory language and history belie any such intention. We therefore conclude that we have jurisdiction over this appeal.
III
Appellants’ First Amendment claim is based largely on this Court’s decision in Buckley v. Valeo, 424 U. S. 1 (1976) (per curiam,). That case involved a broad challenge to the constitutionality of the 1974 Amendments to the Federal Election Campaign Act. We held, inter alia, that the limitations placed by the Act on campaign expenditures violated the First Amendment in that they directly restrained the rights of citizens, candidates, and associations to engage in protected political speech. Id., at 39-59. Nonetheless, we upheld the various ceilings the Act placed on the contributions individuals and multicandidate political committees could make to candidates and their political committees, and the maximum aggregate amount any individual could contribute in any calendar year. We reasoned that such contribution restrictions did not directly infringe on the ability of contributors to express their own political views, and that such limitations served the important governmental interests in preventing the corruption or appearance of corruption of the political process that might result if such contributions were not restrained. Id., at 23-38.
Although the $5,000 annual limit imposed by § 441a (a) (1)(C) on the amount that individuals and unincorporated associations may contribute to political committees is, strictly speaking, a contribution limitation, appellants seek to bring their challenge to this provision within the reasoning of Buckley. First, they contend that § 441a (a) (1) (C) is akin to an unconstitutional expenditure limitation because it restricts the ability of CMA to engage in political speech through a political committee, CALPAC. Appellants further contend that even if the challenged provision is viewed as a contribution limitation, it is qualitatively different from the contribution restrictions we upheld in Buckley. Specifically, appellants assert that because the contributions here flow to a political committee, rather than to a candidate, the danger of actual or apparent corruption of the political process recognized by this Court in Buckley as a sufficient justification for contribution restrictions is not present in this case.
While these contentions have some surface appeal, they are in the end unpersuasive. The type of expenditures that this Court in Buckley considered constitutionally protected were those made independently by a candidate, individual, or group in order to engage directly in political speech. Id., at 44-48. Nothing in § 441a (a)(1)(C) limits the amount CMA or any of its members may independently expend in order to advocate political views; rather, the statute restrains only the amount that CMA may contribute to CALPAC. Appellants nonetheless insist that CMA’s contributions to CALPAC should receive the same constitutional protection as independent expenditures because, according to appellants, this is the manner in which CMA has chosen to engage in political speech.
We would naturally be hesitant to conclude that CMA’s determination to fund CALPAC rather than to engage directly in political advocacy is entirely unprotected by the First Amendment. Nonetheless, the ‘‘speech by proxy” that CMA seeks to achieve through its contributions to CALPAC is not the sort of political advocacy that this Court in Buckley found entitled to full First Amendment protection. CALPAC, as a multicandidate political committee, receives contributions from more than 50 persons during a calendar year. 2 U. S. C. § 441a (a)(4). Thus, appellants’ claim that CALPAC is merely the mouthpiece of CMA is untenable. CALPAC instead is a separate legal entity that receives funds from multiple sources and that engages in independent political advocacy. Of course, CMA would probably not contribute to CALPAC unless it agreed with the views espoused by CALPAC, but this sympathy of interests alone does not convert CALPAC’s speech into that of CMA.
Our decision in Buckley precludes any argument to the contrary. In that case, the limitations on the amount individuals could contribute to candidates and campaign organizations were challenged on the ground that they limited the ability of the contributor to express his political views, albeit through the speech of another. The Court, in dismissing the claim, noted:
“While contributions may result in political expression if spent by a candidate or an association to present views to the voters, the transformation of contributions into political debate involves speech by someone other than the contributor.” 424 U. S., at 21 (emphasis added).
This analysis controls the instant case. If the First Amendment rights of a contributor are not infringed by limitations on the amount he may contribute to a campaign organization which advocates the views and candidacy of a particular candidate, the rights of a contributor are similarly not impaired by limits on the amount he may give to a multicandidate political committee, such as CALPAC, which advocates the views and candidacies of a number of candidates.
We also disagree with appellants’ claim that the contribution restriction challenged here does not further the governmental interest in preventing the actual or apparent corruption of the political process. Congress enacted § 441a (a)(1) (C) in part to prevent circumvention of the very limitations on contributions that this Court upheld in Buckley. Under the Act, individuals and unincorporated associations such as CMA may not contribute more than $1,000 to any single candidate in any calendar year. 2 U. S. C. § 441a (a)(1) (A). Moreover, individuals may not mahe more than $25,000 in aggregate annual political contributions. 2 U. S. C. § 441a (a) (3). If appellants’ position — that Congress cannot prohibit individuals and unincorporated associations from making unlimited contributions to multicandidate political committees — is accepted, then both these contribution limitations could be easily evaded. Since multicandi-date political committees may contribute up to $5,000 per year to any candidate, 2 U. S. C. § 441a (a)(2)(A), an individual or association seeking to evade the $1,000 limit on contributions to candidates could do so by channelling funds through a multicandidate political committee. Similarly, individuals could evade the $25,000 limit on aggregate annual contributions to candidates if they were allowed to give unlimited sums to multicandidate political committees, since such committees are not limited in the aggregate amount they may contribute in any year. These concerns prompted Congress to enact § 441a (a)(1)(C), and it is clear that this provision is an appropriate means by which Congress could seek to protect the integrity of the contribution restrictions upheld by this Court in Buckley.
IV
Appellants also challenge the restrictions on contributions to political committees on the ground that they violate the equal protection component of the Fifth Amendment. Under the statute, corporations and labor unions may pay for the establishment, administration, and solicitation expenses of a “separate segregated fund to be utilized for political purposes.” 2 U. S. C. § 441b (b)(2)(C). Contributions by these groups to such funds are not limited by the statute. 2 U. S. C. § 431 (8) (B) (vi) (1976 ed., Supp. III). Appellants assert that a corporation’s or a union’s contribution to its segregated political fund is directly analogous to an unincorporated association’s contributions to a multicandidate political committee. Thus, they conclude that because contributions are unlimited in the former situation, they cannot be limited in the latter without violating equal protection.
We have already concluded that § 441a (a)(1)(C) does not offend the First Amendment. In order to conclude that it nonetheless violates the equal protection component of the Fifth Amendment, we would have to find that because of this provision the Act burdens the First Amendment rights of persons subject to § 441a (a) (1) (C) to a greater extent than it burdens the same rights of corporations and unions, and that such differential treatment is not justified. We need not consider this second question — whether the discrimination alleged by appellants is justified — because we find no such discrimination. Appellants’ claim of unfair treatment ignores the plain fact that the statute as a whole imposes far fewer restrictions on individuals and unincorporated associations than it does on corporations and unions. Persons subject to the restrictions of § 441a (a)(1)(C) may make unlimited expenditures on political speech; corporations and unions, however, may make only the limited contributions authorized by § 441b (b)(2). Furthermore, individuals and unincorporated associations may contribute to candidates, to candidates’ committees, to national party committees, and to all other political committees while corporations and unions are absolutely barred from making any such contributions. In addition, multicandidate political committees are generally unrestricted in the manner and scope of their solicitations; the segregated funds that unions and corporations may establish pursuant to § 441b (b) (2) (C) are carefully limited in this regard. §§ 441b (b) (3), 441b (b) (4). The differing restrictions placed on individuals and unincorporated associations, on the one hand, and on unions and corporations, on the other, reflect a judgment by Congress that these entities have differing structures and purposes, and that they therefore may require different forms of regulation in order to protect the integrity of the electoral process. Appellants do not challenge any of the restrictions on the corporate and union political activity, yet these restrictions entirely undermine appellants’ claim that because of § 441a (a) (1) (C), the Act discriminates against individuals and unincorporated associations in the exercise of their First Amendment rights. Cf. Buckley, 424 U. S., at 95-99.
Accordingly, we conclude. that the $5,000 limitation on the amount that persons may contribute to multicandidate political committees violates neither the First nor the Fifth Amendment. The judgment of the Court of Appeals is therefore affirmed.
So ordered.
Under the Act, a political committee is defined to include “any committee . . . which receives contributions aggregating in excess of $1,000 during a calendar year or which makes expenditures aggregating in excess of $1,000 during a calendar year.” 2 U. S. C. § 431 (4) (1976 ed., Supp. III). A “multicandidate political committee” is defined as a “political committee which has been registered under section 433 of this title for a period of not less than 6 months, which has received contributions from more than 50 persons, and . . . has made contributions to 5 or more candidates for Federal Office.” 2 U. S. C. § 441a (a)(4).
Section 441a (a) (1) (C) provides in pertinent part that “[n]o person shall make contributions ... to any other political committee in any calendar year which, in the aggregate, exceed $5,000.” The Act defines the term “person” to include “an individual, partnership, committee, association, corporation, labor organization, or any other organization or group of persons.” 2 U. S. C. § 431 (11) (1976 ed., Supp. III). Corporations and labor organizations, however, are prohibited by 2 U. S. C. § 441b (a) from making any contributions to political committees other than the special segregated funds authorized by §441b (b)(2)(C), and hence these entities are not governed by §441a (a)(1)(C).
This section provides that “[n]o . . . political committee shall knowingly accept any contribution or make any expenditure in violation of the provisions of this section.”
See infra, at 188-189.
In the meantime, the District Court has entered judgment in favor of the Commission in its enforcement action against CMA and CALPAC. Federal Election Comm’n v. California Medical Assn., 502 F. Supp. 196 (1980).
Initially, we reject the Commission's suggestion that appellants may lack standing to raise the claims involved here. The grant of standing under § 437h, which this Court has held to be limited only by the constraints of Art. III of the Constitution, Buckley v. Valeo, 424 U. S. 1, 11 (1976) (per curiam), authorizes actions to be brought by the Commission, the national committee of a political party, and individuals eligible to vote in federal elections. The individual appellants in this case fall within this last category, and, as members and officers of CMA and CALPAC, have a sufficiently concrete stake in this controversy to establish standing to raise the constitutional claims at issue here. Accordingly, we do not address the question whether parties not enumerated in § 437h’s grant of standing, such as CMA and CALPAC, may nonetheless raise constitutional claims pursuant to that section. Arlington Heights v. Metropolitan Housing Dev. Corp., 429 U. S. 252, 264, n. 9 (1977). Compare Martin Tractor Co. v. Federal Election Comm’n, 460 F. Supp. 1017 (DC 1978), aff’d, 200 U. S. App. D. C. 322, 627 F. 2d 375, cert, denied sub nom. National Chamber Alliance for Politics v. Federal Election Comm’n, 449 U. S. 954 (1980), with Bread Political Action Committee v. Federal Election Comm’n, 591 F. 2d 29 (CA7 1979), appeal pending, No. 80-1481.
Senator Buckley introduced the amendment incorporating § 437h into the Act, and noted:
“It merely provides for expeditious review of the constitutional questions I have raised. I am sure we will all agree that if, in fact, there is a serious question as to the constitutionality of this legislation, it is in the interest of everyone to have the question determined by the Supreme Court at the earliest possible time.” 120 Cong. Rec. 10562 (1974).
The sole explanation of this provision in the House was by Representative Frenzel, who stated:
“I believe within this conference report there are at least 100 items questionable from a constitutional standpoint. . . .
“I do call . . . attention ... to the fact that any individual under this bill has a direct method to raise these questions and to have those considered as quickly as possible by the Supreme Court.” Id., at 35140.
Although the Commission now contends that § 437h actions may not be maintained simultaneously with § 437g proceedings raising the same constitutional claims, it has in the past argued that the two review provisions are independent of each other and that §437h actions could be brought by defendants in a § 437g proceeding to adjudicate any constitutional claims arising during the course of such proceedings. Federal Election Comm’n v. Lance, 635 F. 2d 1132, 1137, n. 3 (CA5 1981); Federal Election Comm’n v. Central Long Island Tax Reform Immediately Committee, 616 F. 2d 45, 48-49 (CA2 1980).
Even if the Commission’s proposed construction of the statute were accepted, it remains unclear whether we would be required to dismiss this appeal. The only defendants in the Commission’s § 437g enforcement proceeding are CMA and CALPAC. However, the plaintiffs in the § 437h action include, along with CALPAC and CMA, two individual doctors. These individuals have standing to bring this action, see n. 6, supra, and the Commission apparently does not contend that such parties, who are not involved in a pending or ongoing enforcement proceeding, are barred from invoking the § 437h procedure.
The legislative history of the 1974 Amendments is silent on the interaction of the two provisions. However, the brief discussion in Congress of § 437h indicates that it was intended to cover all serious constitutional challenges to the Act. See n. 7, supra.
The Commission suggests that the language of § 437h, authorizing eligible plaintiffs to “institute such actions . . . , including actions for declaratory judgments, as may be appropriate to construe the constitutionality of any provision of the Act,” confers on the district court discretion to dismiss as "inappropriate” § 437h suits raising constitutional claims that are also presented in § 437g proceedings. We do not agree that the word “appropriate” embodies the broad substantive limitation proposed by the Commission. As the reference to declaratory judgment actions in the preceding clause makes clear, the concept of an “appropriate” action refers only to the form in which the litigation is cast. Thus, for example, a suit for damages would not be an “appropriate” action for testing the facial validity of the Act. In any event, whatever ambiguity surrounds the meaning of the word “appropriate” in § 437h is dispelled by the section’s command that the district court “immediately . . . certify all questions of constitutionality” to the court of appeals. (Emphasis added.)
The judgments of the courts of appeals in § 437g cases are reviewable in this Court only upon certification or writ of certiorari. § 437g (a) (9). In contrast, the judgments of the courts of appeals in § 437h proceedings may be directly appealed to this Court. §437h(b).
In reaching a contrary conclusion, the dissent today engages in a most unusual method of statutory interpretation. Although § 437h expressly requires a district court to “immediately . . . certify all questions of the constitutionality” of the Act to the court of appeals and although the legislative history of that provision clearly indicates Congress’ intent to have constitutional challenges to the Act resolved through the § 437h procedure, the dissent blithely concludes that “neither the language of the Act nor its legislative history directly addresses the issue” before the Court today. Post, at 205. Having so neatly swept aside the relevant statutory language and history, the dissent proceeds to rewrite the statute in a manner it perceives as necessary to insure the “proper enforcement of the Act and . . . the sound functioning of the federal courts . . . .” Ibid. Under this reconstruction, § 437h may not be invoked by a party who has been “formally notified of a § 437g proceeding”; indeed, that provision may not even be used by those with an “identity of . . . interests” with a party who has been so notified. Post, at 208. While the concepts of “formal notification” and “identity of interests” which the dissent seeks to engraft on § 437h might well benefit the Commission in its effort to enforce the Act and might relieve the courts of appeals of the burden of some § 437h actions, the task before us is not to improve the statute but to construe it. We have already acknowledged that the statute, as we interpret it today, is subject to the criticisms raised by the dissent. Supra, at 190. The remedy, however, lies with Congress.
Moreover, in its effort to justify rewriting § 437h, the dissent exaggerates the burden § 437h actions have placed on the federal courts. To date, there have been only a handful of cases certified to the Courts of Appeals under this procedure. Anderson v. Federal Election Comm’n, 634 F. 2d 3 (CA1 1980); Federal Election Comm’n v. Central Long Island Tax Reform Immediately Committee, 616 F. 2d 45 (CA2 1980); Republican National Committee v. Federal Election Comm’n, 616 F. 2d 1 (CA2 1979), summarily aff’d, 445 U. S. 955 (1980); Federal Election Comm’n v. Lance, 635 F. 2d 1132 (CA5 1981); Bread Political Action Committee v. Federal Election Comm’n, 591 F. 2d 29 (CA7 1979), appeal pending, No. 80-1481; Buckley v. Valeo, 171 U. S. App. D. C. 172, 519 F. 2d 821 (1975), aff’d in part and rev’d in part, 424 U. S. 1 (1976); Clark v. Valeo, 182 U. S. App. D. C. 21, 559 F. 2d 642 (1972), summarily aff’d sub nom. Clark v. Kimmitt, 431 U. S. 950 (1977); Martin Tractor Co. v. Federal Election Comm’n, 200 U. S. App. D. C. 322, 627 F. 2d 375, cert, denied sub nom. National Chamber Alliance for Politics v. Federal Election Comm’n, 449 U. S. 954 (1980). Moreover, the Federal Election Campaign Act is not an unlimited fountain of constitutional questions, and it is thus reasonable to assume that resort to § 437h will decrease in the future. Under these circumstances, we do not believe that § 437h poses any significant threat to the effective functioning of the federal courts.
While we thus decline to adopt the Commission’s view, we believe that its concerns about the potential abuse of §437h are in large part answered by the other restrictions on the use of that section. The unusual procedures embodied in this section are, at the very least, circumscribed by the constitutional limitations on the jurisdiction of the federal courts. Buckley v. Valeo, 424 U. S., at 11. A party seeking to invoke § 437h must have standing to raise the constitutional claim. Ibid. Furthermore, § 437h cannot properly be used to compel federal courts to decide constitutional challenges in cases where the resolution of unsettled questions of statutory interpretation may remove the need for constitutional adjudication. Federal Election Comm’n v. Central Long Island Tax Reform Immediately Committee, supra, at 51-53. See Nixon v. Administrator of General Services, 433 U. S. 425, 438 (1977); Thorpe v. Housing Authority, 393 U. S. 268, 283-284 (1969); Crowell v. Benson, 285 U. S. 22, 62 (1932). Moreover, we do not construe § 437h to require certification of constitutional claims that are frivolous, see, e. g., Gifford v. Congress, 452 F. Supp. 802 (ED Cal. 1978); cf. California Water Service Co. v. City of Redding, 304 U. S. 252, 254-255 (1938) (per curiam), or that involve purely hypothetical applications of the statute. See, e. g., Clark v. Valeo, supra; Martin Tractor Co. v. Federal Election Comm’n, supra; 627 F.2d, at 384-386, 388-390. Finally, as a practical matter, immediate adjudication of constitutional claims through a § 437h proceeding would be improper in cases where the resolution of such questions required a fully developed factual record. See, e. g., Anderson v. Federal Election Comm’n, supra; Martin Tractor Co. v. Federal Election Comm’n, supra, at 325, 627 F. 2d, at 378; Mott v. Federal Election Comm’n, 494 F. Supp. 131, 135 (DC 1980). These restrictions, in our view, enable a district court to prevent the abuses of § 437h envisioned by the Commission.
None of these considerations, however, pertain to this case. At least the individual appellants have standing to bring this challenge. See n. 6, supra. Additionally, appellants here expressly challenge the statute on its face, and there is no suggestion that the statute is susceptible to an interpretation that would remove the need for resolving the constitutional questions raised by appellants. Finally, as evidenced by the divided en banc court below, the issues here are neither insubstantial nor settled. We therefore conclude that this case is properly before us pursuant to § 437h.
Specifically, this Court upheld the $1,000 limit on the amount a person could contribute to a candidate or his authorized political committees, 2 U. S. C. §441a (a)(1)(A), the $5,000 limit on the contributions by a multicandidate political committee to a candidate or his authorized political committee, 2 U. S. C. § 441a (a) (2) (A), and the overall $25,000 annual ceiling on individual contributions, 2 U. S. C. § 441a (a) (3).
In Buckley, this Court concluded that the act of contribution involved some limited element of protected speech.
“A contribution serves as a general expression of support for a candidate and his views, but does not communicate the underlying basis for the support. The quantity of communication by the contributor does not increase perceptibly with the size of his contribution, since the expression rests solely on the undifferentiated, symbolic act of contributing. At most, the size of the contribution provides a very rough index of the intensity of the contributor’s support for the candidate. A limitation on the amount of money a person may give to a candidate or campaign organization thus involves little direct restraint on his political communication, for it permits the symbolic expression of support evidenced by a contribution but does not in any way infringe the contributor’s freedom to discuss candidates and issues.” 424 U. S., at 21 (footnote omitted).
Under this analysis, CMA’s contributions to CALPAC symbolize CMA’s general approval of CALPAC’s role in the political process. However, this attenuated form of speech does not resemble the direct political advocacy to which this Court in Buckley accorded substantial constitutional protection.
Amicus American Civil Liberties Union suggests that § 441a (a) (1) (C) would violate the First Amendment if construed to limit the amount individuals could jointly expend to express their political views. We need not consider this hypothetical application of the Act. The case before us involves the constitutionality of § 441a (a) (1) (C) as it applies to contributions to multieandidate political committees. Under the statute, these committees are distinct legal entities that annually receive contributions from over 50 persons and make contributions to 5 or more candidates for federal office. 2 U. S. C. § 441a (a)(4). Contributions to such committees are therefore distinguishable from expenditures made jointly by groups of individuals in order to express common political views.
The Conference Report on the provision in the 1976 amendments to the Act that became § 441a (a) (1) (C) specifically notes:
“The conferees’ decision to impose more precisely defined limitations on the amount an individual may contribute to a political committee, other than a candidate’s committees, and to impose new limits on the amount a person or multicandidate committee may contribute to a political committee, other than candidates’ committees, is predicated on the following considerations: first, these limits restrict the opportunity to circumvent the $1,000 and $5,000 limits on contributions to a candidate; second, these limits serve to assure that candidates’ reports reveal the root source of the contributions the candidate has received; and third, these limitations minimize the adverse impact on the statutory scheme caused by political committees that appear to be separate entities pursuing their own ends, but are actually a means for advancing a candidate’s campaign.” H. R. Conf. Rep. No. 94-1057, pp. 57-58 (1976).
Appellants suggest that their First Amendment concerns would be satisfied if this Court declared § 441a (a) (1) (C) unconstitutional to the extent that it restricts CMA’s right to contribute administrative support to CALPAC. The Act defines “contribution” broadly to include “any gift, subscription, loan, advance, or deposit of money or anything of value . . . or . . . the payment by any person of compensation for the personal services of another person which are rendered to a political committee without charge for any purpose.” 2 U. S. C. §§431 (8) (A) (i), (ii) (1976 ed., Supp. III).
Thus, contributions for administrative support clearly fall within the sorts of donations limited by § 441a (a) (1) (C). Appellants contend, however, that because these contributions are earmarked for administrative support, they lack any potential for corrupting the political process. We disagree. If unlimited contributions for administrative support are permissible, individuals and groups like CMA could completely dominate the operations and contribution policies of independent political committees such as CALPAC. Moreover, if an individual or association was permitted to fund the entire operation of a political committee, all moneys solicited by that committee could be converted into contributions, the use of which might well be dictated by the committee’s main supporter. In this manner, political committees would be able to influence the electoral process to an extent disproportionate to their public support and far greater than the individual or group that finances the committee’s operations would be able to do acting alone. In so doing, they could corrupt the political process in a manner that Congress, through its contribution restrictions, has sought to prohibit. We therefore conclude that §441a (a)(1)(C) applies equally to all forms of contributions specified in § 431 (8) (A), and assess appellants’ constitutional claims from that perspective.
We also reject appellants’ contention that even if § 441a (a) (1) (C) is a valid means by which Congress could seek to prevent circumvention of the other contribution limitations embodied in the Act, it is superfluous and therefore constitutionally defective because other antifraud provisions in the Act adequately serve this end. See, e. g., 2 U. S. C. §§441a (a) (7), 441a (a) (8). Because we conclude that the challenged limitation does not restrict the ability of individuals to engage in protected political advocacy, Congress was not required to select the least restrictive means of protecting the integrity of its legislative scheme. Instead, Congress could reasonably have concluded § 441a (a) (1) (C) was a useful supplement to the other antifraud provisions of the Act. Cf. Buckley v. Valeo, 424 U. S., at 27-28 (rejecting contention that effective bribery and disclosure statutes eliminated need for contribution limitations).
