Today, oral arguments will be heard in the case Yes on Term Limits v. Savage at the federal 10th Circuit Court of Appeals in Denver, Colorado. The case is a constitutional challenge to Oklahoma’s statute requiring that people who circulate a petition must be residents of Oklahoma.

The Oklahoma 3—Paul, Rick Carpenter, and Susan Johnson—are under indictment for allegedly violating Oklahoma’s residency requirement. If the residency statute is invalidated as a violation of the First Amendment rights of citizens, the prosecution of the OK-3 could not go forward.

The three-judge panel that will hear the case consists of Judges Michael W. McConnell, appointed by George W. Bush; Monroe G. McKay, a Carter appointee; and Michael R. Murphy, a Clinton appointee.

Back in July, the federal 9th Circuit Court of Appeals struck down Arizona’s residency law as unconstitutional in the case Nader v. Brewer.
