History: 1995 a. 72; 1999 a. 150 s. 260; Stats. 1999 s. 66.0409; 2011 a. 35; 2015 a. 149; 2019 a. 124.
This section does not prohibit municipalities from enacting and enforcing zoning ordinances that apply to sport shooting ranges. Town of Avon v. Oliver, 2002 WI App 97, 253 Wis. 2d 647, 644 N.W.2d 260, 01-1851.
The scope of legislative activity covered by “ordinances” and “resolutions” extends to formal and informal enactments that address matters both general and specific in a manner meant to be either temporary or permanent and that can be characterized as administrative or otherwise, regardless of how they may be denominated. There is no legislative action a municipality could take that would not come within the ambit of ordinance or resolution. If a statute removes the authority of a municipality's governing body to adopt an ordinance or resolution on a particular subject, the governing body loses all legislative authority on that subject. Wisconsin Carry, Inc. v. City of Madison, 2017 WI 19, 373 Wis. 2d 543, 892 N.W.2d 233, 15-0146.
Under sub. (2), the legislature has withdrawn from municipalities all authority to legislate on the possession, bearing, or transportation of any knife or any firearm unless the legislation is the same as or similar to, and no more stringent than, a state statute. Because a municipality cannot delegate what it does not have, a municipality is entirely powerless to authorize any of its subunits to legislate on this subject. Wisconsin Carry, Inc. v. City of Madison, 2017 WI 19, 373 Wis. 2d 543, 892 N.W.2d 233, 15-0146.
This section forbids a municipality from forbidding weapons on its buses when otherwise carried in conformance with the law. To the extent that a municipality previously had a property-based right to exclude riders in possession of weapons, that right ceased with the advent of this section. Wisconsin Carry, Inc. v. City of Madison, 2017 WI 19, 373 Wis. 2d 543, 892 N.W.2d 233, 15-0146.
