MADISON, Wis. (AP) — Wisconsin Attorney General Brad Schimel has filed a brief with the state Supreme Court supporting guns on Madison city buses.

Gun rights group Wisconsin Carry filed a lawsuit in 2014 alleging a Madison Transit and Parking Commission rule prohibiting weapons on buses can't stand in the face of a state law barring local governments from enacting ordinances or resolutions regulating guns that are more restrictive than state statutes.

The 4th District Court of Appeals upheld the ban in August, saying the prohibition is a rule, not an ordinance or resolution.

Wisconsin Carry has appealed to the Supreme Court.

Schimel, a Republican, filed a brief Wednesday in support of Wisconsin Carry arguing municipalities can't trump a state law that allows people to possess and transport firearms in vehicles.
