An incumbent Democrat narrowly won re-election to the state’s highest court. But the Republican-controlled court is considering an unusual protest from her challenger that could flip the result.

A federal appeals court has agreed to hear more arguments involving a close election in November for a North Carolina Supreme Court seat.

The federal Fourth Circuit Court of Appeals on Friday said it will hear Republican State appeals court Judge Jefferson Griffin’s elections case, where he’s seeking to invalidate more than 60,000 votes in the race for a seat on the North Carolina Supreme Court.

Over two months since Election Day, the state has still not officially declared a winner and the race has been upended by protracted legal challenges.
