BUCKLEY v. VALEO
1
Per Curialn
ation. The Court's decisions involving associational
freedoms establish that the right of association is a "basic
constitutional freedom," Kusper v. Pontikes, 414 U. S.,
at 57, that is "closely allied to freedom of speech and a
right which, like free speech, lies at the foundation of a
free society." Shelton v. Tucker, 364 U. S. 479, 486
(1960). See, e. g., Bates v. Little Rock, 361 U. S. 516,
522-523 (1960); NAACP v. Alabama, supra, at 460-461;
NAACP v. Button, supra, at 452 (Harlan, J., dissenting). In view of the fundamental nature of the right to
associate, governmental "action which may have the effect
of curtailing the freedom to associate is subject to the
closest scrutiny." NAACP v. Alabama, supra, at 460461. Yet, it is clear that "[n] either the right to associate
nor the right to participate in political activities is absolute." CSC v. Letter Carriers,413 U. S. 548, 567 (1973).
Even a " 'significant interference' with protected rights
of political association" may be sustained if the State
demonstrates a sufficiently important interest and employs means closely drawn to avoid unnecessary abridgment of associational freedoms. Cousins v. Wigoda,
supra, at 488; NAACP v. Button, supra, at 438; Shelton
v. Tucker, supra, at 488.
Appellees argue that the Act's restrictions on large
campaign contributions are justified by three governmental interests. According to the parties and amici,
the primary interest served by the limitations and, indeed, by the Act as a whole, is the prevention of corruption and the appearance of corruption spawned by the
real or imagined coercive influence of large financial contributions on candidates' positions and on their actions
if elected to office. Two "ancillary" interests underlying
the Act are also allegedly furthered by the $1,000 limits
on contributions. First, the limits serve to mute the
voices of affluent persons and groups in the election
