Brown v. ATF has not been decided. On October 7, 2026, the Justice Department asked the Missouri court to keep any NFA relief off whole states and limit it to the plaintiffs themselves.

Brown v. ATF, the Missouri lawsuit that could extend NFA relief to members of FPC, NRA, SAF and the American Suppressor Association, still has no ruling, and the Justice Department told the court on October 7, 2026 that it should not let the eleven states that joined the fight win protection for every resident inside their borders.
Brown v. ATF at a Glance
- The case: Brown v. ATF, No. 4:25-cv-01162 (E.D. Mo.), joined with Missouri’s own suit, No. 4:26-cv-01430.
- What DOJ filed: an October 7, 2026 brief saying statewide and nationwide relief are off the table and five states are barred because they already won in Texas.
- What DOJ conceded: Missouri “appears to have complied” with the rules when it amended its complaint.
- Next date: a status conference set by Chief Judge Stephen R. Clark for October 22, 2026, at 10 a.m. Central.
- What changes for buyers: nothing yet. Coverage still runs through the Texas injunction.
What Is Brown v. ATF?
Brown v. ATF is the Missouri NFA lawsuit that challenges National Firearms Act registration for items that now carry a $0 tax. The plaintiffs are individual gun owners plus Firearms Policy Coalition, the National Rifle Association, the Second Amendment Foundation, the American Suppressor Association and Prime Protection STL, according to the court docket. Missouri filed its own suit, and the court joined the two.
That matters because the Texas injunction in Silencer Shop Foundation v. ATF only protects the plaintiffs there, their members and their customers. Members of FPC, NRA, SAF and ASA are not covered by Texas just for being members. A win in Brown is how that group gets in. Having worked behind the counter for over 20 years, I have gotten one question more than any other since August: does the ruling cover the customer standing in front of me? This case is a big part of that answer.
What Did DOJ Argue on October 7?
The government’s third supplemental brief (Document 114, filed October 7, 2026) does not argue the merits of NFA registration at all. It goes after the scope of relief, in four steps.
- No nationwide order. The states asked to block enforcement “within the territory of the Plaintiff States, and within the United States.” DOJ says that is “foreclosed by Trump v. CASA,” the 2025 Supreme Court decision that limited universal injunctions.
- No statewide order either. DOJ calls the states’ harm theory a “thinly veiled attempt” at parens patriae standing, meaning a state suing on behalf of its residents in general, and says “the federal government is ‘the ultimate parens patriae of every American citizen.'”
- Five states are out. DOJ says Kansas, Georgia, Oklahoma, South Dakota and Utah already took the same claims to final judgment in Texas, calls it “a textbook case of claim preclusion,” and asks the court to “dismiss these five states from this case.”
- Missouri gets a narrow lane. DOJ says Missouri is “the only state that has attempted to substantiate a valid theory of standing,” and that it can seek relief only for harms from the NFA regulating the state itself as a buyer and owner of NFA items, “and nothing more.”
One thing went Missouri’s way. DOJ wrote that “Missouri appears to have complied with the Federal Rules of Civil Procedure in amending its complaint.” (Small victories. Lawyers count them too.)
Which States Are in the Missouri NFA Case?
The amended complaint, filed September 24, 2026, lists Missouri and Missouri resident Dave Marshak, plus Kansas, Florida, Georgia, Iowa, Nebraska, New Hampshire, Ohio, Oklahoma, South Dakota and Utah. DOJ says ten of those states “submitted no evidence in support of their standing,” which leaves Missouri as the only state it treats as having put anything in the record.
What Happens at the October 22 Status Conference?
Chief Judge Stephen R. Clark’s October 6, 2026 order noted that the October 5 deadline to appeal the Texas injunction passed with no appeal, and set a Zoom status conference for October 22, 2026, at 10 a.m. Central. Lead counsel must be ready to discuss three things:
- What the final Texas judgment in Silencer Shop Foundation means for this case.
- Whether Georgia, Kansas, Oklahoma, South Dakota and Utah have standing.
- Whether Missouri’s amended complaint was valid.
The order says members of the public may listen by phone. A status conference is not a ruling, so do not expect an order on summary judgment that morning, though the judge could rule any time after.
How Does This Tie to the Texas Injunction?
The same fight is running in Texas. The state plaintiffs there asked Judge James Wesley Hendrix to clarify whether his injunction covers everyone in their states or only members and customers of the organizations that sued. Judge Hendrix gave the government until October 12, 2026 to respond (Document 146). DOJ’s Missouri brief tells you where it is likely headed. It says the states’ request for clarification in Texas is “part of the remedy they seek here,” and it opposes that remedy in Missouri.
So DOJ let the Texas ruling stand, and it is now fighting to keep that ruling, and any Missouri ruling, from reaching people who are not plaintiffs, members or customers. I walked through who is covered in our tracker of who can buy a suppressor without a Form 4, and why the appeal never came in our story on the October 5 deadline.
What Does Brown v. ATF Mean for Suppressor Buyers?
Nothing changes yet. If you are a member or customer of a Texas plaintiff, you are covered by that injunction. If you are an FPC, NRA, SAF or ASA member and nothing else, you are waiting on Brown. If you live in one of the eleven states but belong to none of those groups, DOJ is arguing that your state’s lawsuit does not cover you. Buy through a dealer who checks coverage, keep proof of membership, and do not cross state lines with a suppressor until you have read our guide to suppressor interstate travel.
