Legislative rules may be established through the actions of each house, or both houses, of the Legislature. Parliamentary procedure, prescribing how the Legislature and legislative committees operate, is set forth in the Assembly Rules Manual and the Senate Rules Manual. In addition to the rules of each house, the Legislature has established joint rules. Legislative rules may also be created through the lawmaking process. In either case, the Wisconsin Supreme Court has consistently held that, absent a constitutional violation, the Court will not interfere with the legislative process the Legislature follows in passing laws. Furthermore, the failure to comply with legislative rules, absent a constitutional violation, will not invalidate enacted legislation.
This issue brief provides examples of statutory legislative rules and describes the major Wisconsin Supreme Court cases describing the judicial branch’s jurisdiction over the application of legislative rules.
