The Supreme Court on Monday said that its landmark 2003 ruling upholding the McCain-Feingold campaign reform law did not foreclose all First Amendment challenges to provisions restricting pre-election issue advertising.

The Court remanded to a three-judge panel in Washington, D.C., the case of Wisconsin Right to Life Inc. v. Federal Election Commission, which was argued before the high court Jan. 17 — a remarkably quick turnaround for a contentious issue.
