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 state Supreme Court justice won a narrow victory in November. Her challenger argues tens of thousands of votes should be thrown out.

The State Board of Elections is now temporarily blocked from certifying Allison Riggs as the winner in the Supreme Court election while the court considers her opponent’s challenge of 60,000 ballots.
