A team from Wilson Sonsini Goodrich & Rosati is representing the Delaware governor’s office pro bono at the U.S. Supreme Court, challenging a federal appeals court ruling that threatens to upend how the state structures its judiciary, contract records show.

Wilson Sonsini’s Randy Holland, formerly a longtime Delaware Supreme Court justice, reached out to the office of Gov. John Carney not long after the U.S. Court of Appeals for the Third Circuit said it would not reconsider its ruling against the state. The appeals court struck down a provision of the Delaware Constitution that essentially says judges must be a member of either the Democratic or Republican parties.
