Judge Strikes Down Ghost Gun Rule

A federal judge struck down the Biden administration's ghost gun rule as unconstitutional and impossibly vague, while a separate GOA lawsuit and a ransomware breach at ATF keep the pressure on the agency's registry of gun owners.

Legal Issues
  • Second Amendment challenge to ATF's definition of a firearm
  • Void-for-vagueness doctrine applied to administrative rulemaking
  • Scope and limits of injunctive relief in federal firearms litigation
What It Means
  • Ruling protects only plaintiffs in the Defense Distributed/SAF lawsuit unless you're covered by a similar injunction
  • Government can still appeal to the Fifth Circuit, so the rule isn't dead nationwide
  • GOA's separate Morehouse case continues to challenge both the frame/receiver rule and ATF's gun owner registry
  • Dealers covered by GOA's NFA injunction have passed ATF inspections selling suppressors without Form 4 registration
  • FFLs should consult a licensed attorney before changing sales practices based on any injunction

Judge Strikes Down Ghost Gun Rule

A federal court found the Biden-era rule unconstitutional and too vague to enforce, but the fight over ATF's definition of a firearm is far from over.

From The Boise Gun Club Handbook

A federal judge in Texas tore up the rule that let ATF treat unfinished chunks of plastic and metal as fully regulated firearms.

State of play: U.S. District Judge Reed O'Connor ruled on August 17 that the Biden administration's "frame or receiver" rule violates the Second Amendment and is unconstitutionally vague. The rule never drew a clear line for when a block of material becomes a gun — it handed ATF a checklist of factors and let the agency decide case by case. Guess wrong, and you're a felon.

Defense Distributed and the Second Amendment Foundation brought the case and won it. Credit belongs with them. But the ruling only protects the plaintiffs in that specific lawsuit, and the Justice Department can still appeal to the Fifth Circuit.

Gun Owners of America has been fighting the same rule since 2022 in a separate case, Morehouse Enterprises v. ATF, filed in North Dakota with a gun shop as co-plaintiff. That suit also challenges ATF's registry of gun owners — a detail that matters more than it sounds like, given what's happening elsewhere.

The intrigue: In GOA's separate NFA lawsuit, a Texas judge already ruled that gun dealers covered by the injunction can sell suppressors using a standard background check form — no Form 4, no federal registration entry. Four of those dealers have since been inspected by ATF. All four came back clean. Inspectors didn't flag the sales, because the court order shields them.

ATF hasn't put anything in writing about it. GOA says it asked the agency for official guidance weeks ago and got silence — not even a confirmation the request arrived. If you're not a GOA member covered by that injunction, none of this applies to you. Anyone running an FFL should talk to a licensed attorney before changing how they do business.

What to watch: A ransomware gang calling itself Qilin claimed to have breached ATF last week, and the bureau confirmed it. ATF says the compromised system was a standalone machine tied to active investigations, not connected to eForms or its broader databases, and that gun owner records weren't taken. The Justice Department has classified it as a major incident, which triggers mandatory notification to Congress.

Nobody outside ATF has verified what the hackers actually got. And the bigger problem doesn't go away even if this breach turns out to be contained: ATF is sitting on paperwork covering roughly a billion guns and owners, including records from gun shops that shut down years ago. Every one of those files is a target for the next attacker.

The bottom line: One court just said the ghost gun rule can't stand as written. That's a real win, but it's narrow, appealable, and doesn't touch the registry itself. GOA is pushing the White House to delete ATF's digital records and backing the No REGISTRY Rights Act to force certified destruction of the data — the same fight that's now colliding with a live ransomware breach.
