Reversing a decision by the Fourth Circuit, the U.S. Supreme Court issued a unanimous opinion that a federal district court judge erred in dismissing a suit against Maryland’s redistricting plan on First Amendment grounds without letting it go before a three-judge panel. As a result, the case is remanded, presumably so that the petitioner can make his case before a three-judge panel.

Winning a rehearing on an appeal over improper procedure is a long way from winning the challenge. Still, it gives new judicial life to a debate over the legality over Maryland’s congressional redistricting plan that the State had thought had been put to bed. (h/t Rick Hasen).
