Timing
Expected by late June 2026, if argued this term
The Court granted review but has not yet scheduled oral argument. Once argued, the median case reaches a decision in 94 days. Nearly all cases are decided by the end of the term in which they are argued.
Briefing
What it's about
A petition from the Ninth Circuit asks the Supreme Court to review California's ban on feeding devices that hold more than 10 rounds of ammunition. The question is whether the Second Amendment protects possession of those commonly owned items.
Argument
The case is pending, and oral argument has not been scheduled. The petition says Heller and Bruen protect weapons that are "in common use at the time" and challenges California's over-10-round ban.
Impact
The answer could affect Californians who want to own those devices and the state officials who enforce the ban. It could also guide other courts weighing gun limits after Heller and Bruen.
What is the core dispute in Duncan v. Bonta?
The case asks whether the Second Amendment protects ammunition feeding devices that hold more than 10 rounds. California bans those devices.
Who could be affected by Duncan v. Bonta?
California gun owners who want those devices and state officials enforcing the ban are directly affected. Other courts may also look to the case.
What happens next in Virginia Duncan v. Bonta?
Oral argument has not been scheduled. Watch for another scheduling move from the Court; no decision window is available yet.
