It doesn't have to go to the governor. If the case doesn't go to that three-judge panel, there's another process, a motion for appropriate relief process. The prosecution and the defence could file a motion for appropriate relief, as opposed to the three-judge panel process. If they go through that process based on innocence, in order to be declared innocent in North Carolina, then you would have to get a pardon from the governor.
You can either go through this three-judge panel and be declared innocent or you can file a motion for appropriate relief. But if you go that route, then you have to have a pardon of innocence in order to be declared innocent and get compensation from the state.
