A federal judge in Texas struck down the Biden administration’s ATF “ghost gun” rule as violating the Second Amendment and the Due Process Clause, setting up a likely appeals battle and raising fresh questions about how far agencies can stretch statutory authority into constitutional rights.
U.S. District Judge Reed O’Connor, sitting in the Northern District of Texas, ruled for two gun rights groups that challenged the 2022 ATF regulation that redefined “frame or receiver” under the Gun Control Act of 1968. The rule aimed to require serial numbers on commercial parts kits and background checks for buyers, but O’Connor found it unconstitutional on both Second Amendment and vagueness grounds. His opinion directly addresses constitutional questions the Supreme Court left open last year.
The Supreme Court had earlier upheld the ATF’s statutory authority in a 7-2 decision, while explicitly declining to decide any constitutional issues. Justice Neil Gorsuch warned in that majority opinion that tougher questions would follow. O’Connor took up one of those tougher questions and concluded the Constitution does not permit the regulation as written.
O’Connor grounded his Second Amendment analysis in America’s long tradition of personal gunsmithing and self-manufacture of firearms, a practice that predates the republic. He held that restricting access to component parts in a way that inhibits home gunsmithing clashes with that historical tradition and therefore fails constitutional muster. In his opinion he wrote the court could not reconcile the rule with that tradition.
“The Court cannot conclude that the Final Rule’s imposition of ambiguous and far-reaching regulations, which would restrict access to component parts thereby inhibiting home gunsmithing, comports with the Second Amendment.”
Beyond the Second Amendment, O’Connor found the regulation unconstitutionally vague under the Due Process Clause, saying ordinary people could not reasonably know what conduct the rule allowed or forbade. That vagueness problem stands on its own as a fatal defect, separate from the core firearms-rights analysis. When laws leave citizens guessing about legality, courts often strike them down for basic fairness.
The Justice Department has so far issued a cautious response, with a spokesperson saying the department is “evaluating the impact of the court’s ruling.” That phrasing suggests an appeal is likely but not yet decided, and any appeal would probably move to the Fifth Circuit first. Given the constitutional stakes and the prior Supreme Court nod to statutory authority, this dispute looks headed back up the judicial ladder.
Gun rights organizations hailed the decision as a major win and a check on bureaucratic overreach. Adam Kraut, executive director of the Second Amendment Foundation, put the group’s position bluntly and raised the vagueness issue as central to the court’s reasoning. His exact words emphasized that the rule both sought to prohibit protected conduct and did so in a way that chilled lawful behavior.
“The Court rightly held that the Biden ATF’s rule not only sought to outright prohibit Second Amendment protected conduct but was written in such a vague and vaporous manner as to chill that protected conduct by making it impossible to even know what was legal and what wasn’t.”
Meanwhile, gun violence prevention groups warned the ruling could create an enforcement gap for untraceable firearms. Emma Brown, executive director of Giffords, argued the injunction could allow people ineligible to possess guns to obtain untraceable ghost guns without checks or training. Her concern highlights why the ATF moved to treat certain parts kits like finished firearms in the first place.
“Under the logic of this injunction, people ineligible to possess guns could get an untraceable ghost gun without any background checks or training. No one wants to live in a country where gun violence is easy to commit and almost impossible for police to solve.”
How far O’Connor’s injunction reaches remains a crucial practical question not spelled out in initial reporting, and that will determine whether the rule stays paused nationwide or in a narrower slice of the country. Courts across the country are already split on related firearm rules, and this opinion adds another significant fracture. The mix of statutory authority and constitutional limits means the legal landscape will keep shifting as appeals work their way through the system.
The ATF regulation traces back to a 1968 statute, but O’Connor’s decision underscores a basic principle: statutory authority does not automatically override constitutional protections. For people who build firearms at home, this ruling affirms a longstanding practice; for regulators who sought to treat every parts kit as a finished weapon, it is a reminder that agencies cannot rewrite constitutional rights through rulemaking. The case now stands poised to test where that line gets drawn.
