Miller et al v Rob Bonta
From the ruling:
“Like the Swiss Army Knife, the popular AR-15 Rifle is a perfect combination of home defense weapon and homeland defense equipment. Good for both home and battle, the AR15 is the kind of versatile gun that lies at the intersection of the kinds of firearms protected under District of Columbiabia v. Heller 554 US 570 (2008) and United States v. Miller 307 US 174 (1939). Yet the State of California makes it a crime to have an AR-15 type rifle. Therefore this court declares the California statutes to be unconstitutional.”
