ANN ARBOR, Mich. (AP) — A judge has dismissed a lawsuit challenging a ban on guns at Ann Arbor schools.

Michigan law bars local governments from regulating guns. But Washtenaw County Judge Carol Kuhnke says the law doesn’t define a school district as a local unit of government.

Jim Makowski, an attorney for a group called Michigan Gun Owners, says he will appeal.

State law says anyone with a concealed pistol license may openly carry a gun into a school. But the Ann Arbor school district’s policy says a firearm on school property is considered an emergency.

In August, a Genesee County judge said a man could openly carry his pistol at his daughter’s school in the Clio district.
