A dispute over the early start to mail-in ballot counting in Maryland is heading to the state highest court. The Maryland Court of Appeals is scheduled to hear arguments in the case on Friday. Last week, a lower court denied an appeal to place a hold on the early canvassing of ballots filed by Republican candidate for Governor, Dan Cox. He claims a judge’s decision to allow vote-counting before Election Day is unconstitutional and the Maryland Board of Elections is now asking the state’s highest court to fast-track a decision on Cox’s appeal.
