The U.S. Supreme Court on Friday agreed to hear Delaware Gov. John Carney’s challenge to a federal appellate ruling earlier this year, which struck down provisions of the Delaware Constitution mandating political party balance on key state courts.

The high court, in a brief order, announced that it had granted certiorari in the case, which could upend Delaware’s unique approach to appointing judges for some of its most influential courts. The justices directed the parties to submit briefing on the questions presented in Carney’s petition, as well as the additional issue of whether the challenger, a retired attorney who said he was overlooked for judgeships, had Article III standing to bring his claims.
