I should have said appealed. A judge will rule that their 5th map is also unconstitutional and they clearly cannot be tasked with making the map. So the judge makes one that would work or tasks a committee to do it. Republicans then appeal that decision because the constitution or a law specifies that the legislature creates the maps. They appeal up to the state Supreme Court.
They would sue the courts? Who would even oversee that? SCOTUS has already said they want no part of state election issues.
