If the Wisconsin Supreme Court Overturns Act 10, the Impact
to Wisconsin Taxpayers Would be in the Billions
Delafield, Wis. – Following Wednesday’s announcement that the Wisconsin Supreme Court will hear a challenge to Act 10, the Institute for Reforming Government (IRG) is warning that the case could have major consequences for Wisconsin taxpayers, local governments and public schools.
The decision puts the 2011 law back before Wisconsin’s highest court just months after the Wisconsin Court of Appeals upheld Act 10 and reversed a Dane County judge’s ruling striking down key portions of the law.
The Background
A Dane County judge struck down major portions of Act 10 in December 2024. In July 2026, the Wisconsin Court of Appeals reversed that decision, concluding that the challenge raised issues already resolved by previous decisions upholding the law and that “the challenged Act 10 provisions do not violate the equal protection guarantees set forth in the Wisconsin Constitution.” The plaintiffs subsequently asked the Wisconsin Supreme Court to take the case. Today, the Court agreed to hear the challenge.
What’s Next
IRG’s Court Watch initiative will continue following the case and educating Wisconsinites about what is at stake as the challenge is heard before the Wisconsin Supreme Court.
