The case, rejected on jurisdictional grounds, was appealed after afederal District Court refused to issue a preliminary injunctionclearing the way for the promotions.

At issue was whetherbroadcast ads promoting the 90-minute documentary "Hillary: The Movie"are subject to strict campaign finance laws on political advocacy, orwould be considered a constitutionally protected form of commercialspeech.

Citizens United, a Washington-based advocacyorganization, had urged the justices to accept its appeal on anexpedited basis this spring, in time for the ads to have an impact onthe election season.
