Former administrative law Judge Roy Pearson hit a snag in a federal appeals court in Washington on Thursday. Call it an admonishment from the bench or maybe a simple “do over.”

A three judge panel of the U.S. Court of Appeals for the D.C. Circuit on Thursday dismissed Pearson’s opening brief in his dispute with the city and a group of judges, saying that Pearson’s court papers failed to comply with the federal rules of appellate procedure regarding the format of briefs.
