The order, in a case brought by several gun owners in 2017 seeking to declare California’s “assault weapon” ban unconstitutional, saw U.S. District Judge Josephine Staton side with the state’s point of view. Staton, extensively citing briefs in the case from anti-gun groups such as the Brady Center, Everytown and Giffords, found that semi-autos banned either by name or cosmetic features such as collapsible stocks or muzzle brakes were basically military-grade hardware.
