MADISON, Wis. (AP) — A lawsuit filed with Wisconsin’s newly liberal-controlled state Supreme Court argues that Republican-drawn legislative maps are unconstitutional and must be redone. The lawsuit Wednesday is the latest legal challenge of many nationwide that could upset political boundary lines before the 2024 election. The long-promised action from a coalition of law firms and voting rights groups comes the day after the Wisconsin Supreme Court flipped from a conservative to liberal majority. The lawsuit is backed by Democrats and argues that the state legislative maps are an unconstitutional gerrymander. The maps were drawn by Republicans and approved by the state Supreme Court when it was controlled by conservative justices. Notably, the lawsuit does not challenge the congressional maps.
