There is no basis for him to file the suit he is filing. He is not making a legal claim made available by law. As for the NC Supreme Court blocking certification, I wouldn’t be surprised if the majority of the court will make up something out of thin air to rule in Griffin’s favor regardless of how frivolous it is. That court’s majority is made up of true political hacks who have no regard for the law and will make things up as they go to get their desired result. Dietz seems to be the only exception with regard to this particular case, as he dissented from the majority’s decision to block certification. It has been virtually unheard of with this current Supreme Court to see one the the Republican justices disagree with the others.
As for both/all parties filing pleadings in court, Riggs and the BOE (separate parties) wouldn’t be filing anything if they didn’t have to respond to Griffin’s pleadings. Even frivolous claims have to be addressed to avoid default judgment.
