WASHINGTON (CNN) - The U.S. Supreme Court said Monday it will reargue an important campaign finance reform case dealing with a scathing documentary about former presidential candidate Hillary Clinton.
The justices put off an expected ruling in the case, and will rehear the issues on September 9. It is unusual for the high court to return early from its summer recess to hear an appeal. The court normally begins its fall term in early October.
The justices apparently could not reach a conclusion on whether the film was subject to federal oversight regarding when and where it could be shown in an election year.
At issue was whether the 90-minute "Hillary: The Movie" - as well as television ads to promote the film - should have been subject to strict campaign finance laws on political advocacy, or was instead a constitutionally protected form of commercial speech.
It is unclear whether high court nominee Sonia Sotomayor will be confirmed in time to hear the case. If not, just eight justices will hear the appeal.
