A federal appeals court has declined to fast-track a challenge against a Minnesota law requiring disclosure of corporate political spending.

In an order Monday, the 8th Circuit Court of Appeals denied a motion to expedite the case, and it scheduled oral arguments for Jan. 11 in St. Louis, well after the election.

Minnesota Citizens Concerned for Life, the Taxpayers League of Minnesota and a travel company are trying to overturn the law on free-speech grounds.

U.S. District Judge Donovan Frank last month refused to block the state law.

The groups have also asked the 8th Circuit for an injunction to suspend enforcement of the disclosure law while their appeal is considered. The appeals court took that request under advisement.
