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. Assuming the case is appealed, it would go next to the Wisconsin Supreme Court, where liberals hold a 4-3 majority that will grow to 5-2 next month. A much different mix of jurists will decide the case on the Wisconsin Supreme Court, where a liberal majority is about to grow. “Renewed attempts to attack Act 10 on already-rejected bases simply because the composition of our Supreme Court has changed must be rejected.”
