So-called ghost guns do not require a serial number under Minnesota law, the state’s Supreme Court concluded in an Aug. 6 decision.
“We conclude that section 609.667(3) criminalizes the possession of a firearm that is not identified by a serial number only if federal law requires that a serial number be stamped, engraved, cast, or otherwise conspicuously placed on the firearm,” Justice Paul C. Thissen wrote for the majority in the 4–2 ruling.
