Testing the bounds of the Supreme Court’s landmark decision in Wisconsin Right to Life II (WRTL II), the Federal Election Commission recently sought to apply certain prohibitions and disclosure requirements of the Bipartisan Campaign Reform Act of 2002 to advocacy group Citizens United’s political documentary, Hillary: The Movie, and to the group’s broadcast advertisements for the film. Though the FEC conceded that the ads, at least, are not the functional equivalent of express campaign advocacy, as defined in WRTL II, it nevertheless determined that Citizens United must disclose the identities of its contributors. Cato’s brief argues that BCRA violates the First Amendment freedom of association belonging to those contributors, which freedom includes the right to associate anonymously and to control the group’s character and message free from government intervention. For groups engaging in political speech, compelled disclosure of contributors’ identities infringes their freedom of private expressive association, a burden often no less severe than direct restraint of the group’s speech. This type of government action must be subject to strict constitutional scrutiny—a level of scrutiny that in practice is almost always fatal. The district court failed to afford sufficient value to associational rights and so failed to scrutinize appropriately the BCRA disclosure provisions’ unjustified infringement on those rights.
