A state appeals court has upheld the landmark collective bargaining law known as Act 10, likely sending the case challenging the law to the Wisconsin Supreme Court. The appeals court’s decision overturned a ruling from a Dane County Circuit Court judge, who declared Act 10 unconstitutional in 2024. After Frost stayed his order, lawyers for unions asked the state Supreme Court to take the case directly on an expedited appeal. Justices declined that request in February 2025, sending the case to the District 2 Court of Appeals, which decided it Wednesday. “Renewed attempts to attack Act 10 on already-rejected bases simply because the composition of our Supreme Court has changed must be rejected.”
