State of California v. ATF

What the court held

California, the Giffords Law Center and two individual plaintiffs sued ATF in 2020 to force regulation of more partially complete receivers, and after ATF's 2022 frame-or-receiver rule issued, their fight narrowed to Example 4 — the rule's statement that a bare AR-15 receiver billet or blank, sold without jigs, templates or tools, is not a receiver. Judge Edward Chen of the Northern District of California granted them summary judgment against Example 4. On August 21, 2026, a Ninth Circuit panel (Callahan, joined by Thomas and Johnstone) vacated that judgment and ordered the case dismissed without prejudice: neither California's spending on ghost-gun enforcement nor Giffords' diverted resources traced causally to Example 4, resting instead on "speculation about the decisions of independent actors . . . particularly speculation about future unlawful conduct." The panel never reached the merits, so the billet carve-out stands and the question whether ATF must regulate bare blanks remains open for a plaintiff who can prove a concrete injury.

What this case is about

Whether California and the Giffords Law Center have standing to challenge Example 4 of ATF's frame-or-receiver rule, which leaves bare receiver blanks unregulated when sold without jigs, templates or tools
