Administrative Laws in Wisconsin.

Wisconsin administrative law is governed by the Wisconsin Administrative Procedure Act (APA, Wis. Stat. ch. 227). 2011 Wisconsin Act 21 substantially restricted agency authority — providing that an agency may not implement or enforce any standard, requirement, or threshold unless explicitly authorized by statute or by rule promulgated under ch. 227. Judicial review of agency action is available in the Circuit Court under Wis. Stat. § 227.52 et seq., with appeals through the Wisconsin Court of Appeals to the Wisconsin Supreme Court.
