Known as Duncan vs Becerra, the case against California’s ban on standard-capacity magazines was brought by the California Rifle & Pistol Association. The Ninth Circuit applied strict scrutiny in its decision and ruled firearm magazines, including those of 30-round capacity or more, are “protected arms under the Second Amendment.” The entire ruling can be read at the United States Court of Appeals For the Ninth Circuit site.
