CLIO, Mich. (AP) — A Genesee County judge has ruled a father can openly carry his pistol inside his daughter’s elementary school.

The Flint Journal reports that Circuit Judge Archie Hayman on Monday ruled in favor of Kenneth Herman and gun rights advocacy group Michigan Open Carry. He filed a lawsuit in March against the Clio Area School District, arguing he was denied access to Edgerton Elementary multiple times while trying to pick up his daughter because he was openly carrying his pistol.

State law allows people with concealed pistol licenses to openly carry their firearms in schools.

The district sought to have the lawsuit dismissed, citing its “fundamental misunderstanding” of Michigan law.

Hayman sided with Herman and his advocates, saying the ability to create local weapon policies is beyond the district’s authority.
