The Supreme Court announced today that it will hold a special public session tomorrow at 10 a.m., reports SCOTUSblog.

The news has fueled speculation that the justices will hand down their long-awaited decision in the campaign finance case Citizens United v. Federal Election Commission. Anticipating this possibility, campaign finance watchers moved their post-decision sessions to tomorrow. Since the Court has no Thursday arguments scheduled, it seems possible that the purpose of this session is to hand down opinions. That said, the Court did not reveal a reason for the move.
