MADISON, Wis. (AP) — Wisconsin Supreme Court justices disagree about whether there will be a chief justice on the court shortly after 9 a.m. on Wednesday. That’s when the state elections board is scheduled to certify results of the April 7 election. Voters approved a constitutional amendment giving justices the power to select who is chief justice, rather than have it go automatically to the most senior member. Longtime Chief Justice Shirley Abrahamson argues in a federal lawsuit she filed that the change shouldn’t be applied until after her current term ends in four years. But five other justices contend that once the vote is certified on Wednesday, there is no chief justice until a new one is selected. Abrahamson was seated as chief justice Tuesday at the court’s public hearing on rule changes.
