A federal appeals court will hear arguments in St. Louis on Friday in a case that challenges the idea that unpaid lobbyists have to register with the Missouri Ethics Commission.

A divided panel of the 8th Circuit Court of Appeals ruled in November that Ron Calzone, a conservative activist, had to fill out the required forms and pay a fine for failing to do so. In a rare move, all 12 judges of the court will reconsider the case.
