Lopez v. Bondi

Plain English (For Everyone)

A California law bans assault weapons and large magazines. People sued, saying this violated their right to bear arms. The court said the ban is okay because these types of weapons aren't commonly used for self-defense and the law fits with historical gun regulations. So, the ban stays in place.

For Legal Practitioners

The Ninth Circuit affirmed the denial of a preliminary injunction, holding that plaintiffs challenging California's assault weapon ban under the Second Amendment failed to establish a likelihood of success. The court applied the Heller/Bruen framework, finding assault weapons are not 'in common use' for lawful purposes and that the ban aligns with historical tradition, distinguishing this case from those involving more common firearms.

For Law Students

This case tests the application of the Heller and Bruen two-step test for Second Amendment challenges. The Ninth Circuit's finding that assault weapons are not 'in common use' and that the ban is historically consistent is crucial for understanding how courts analyze modern firearm regulations against historical tradition, particularly concerning weapons deemed dangerous and unusual.
