On May 1, 2008, in a 2-1 decision the Court of Appeals for the Fourth Circuit ruled a North Carolina law prohibiting political action committees from accepting individual contributions of more than $4,000 to be unconstitutional. In North Carolina Right to Life v. Leake, the Court of Appeals found that the contribution limit as applied to committees making only independent expenditures did not further the state's interest in preventing corruption, therefore burdening the right of political association. As in the Supreme Court's Wisconsin Right to Life decision, the Fourth Circuit Court also found that it was unconstitutional to rely on contextual factors to determine whether a communication "supported" or "opposed" a candidate. The opinion states such "standards typically lead to disputes over their meaning and therefore litigation." [A]ny attempt to identify communications as election-related without focusing on words that explicitly label them as such threatens to infringe on protected First Amendment liberties. . . . Therefore, . . . a communication can be deemed the "functional equivalent of express advocacy only if [it] is susceptible of no reasonable interpretation other than as an appeal to vote for or against a specific candidate." The purpose of this requirement is to avoid chilling political expression by forcing a speaker to have to defend his communication from regulation. Some consider the case to be an "issue that is surely headed to the Supreme Court either in this case or in another case, such as the SpeechNow.org case." SpeechNow.org is challenging federal campaign finance law as too restrictive of independent political groups and as a violation of the First Amendment.
