The Third U.S. Circuit Court of Appeals has ruled New Jersey's decades-old ban on so-called assault firearms and large-capacity magazines unconstitutional, marking the first time a federal appeals court has struck down a state-level ban on such weapons. The 10-5 decision lands squarely on the fault line of American gun politics and hands Second Amendment advocates their most consequential appellate victory in years.
The ruling invalidates New Jersey's prohibition on AR-15-style rifles and its restriction on magazines holding more than 10 rounds. Both provisions had been on the books for years, defended by state officials as essential public safety measures. The Third Circuit disagreed, finding that the bans violate the Second Amendment under the framework the Supreme Court established in its landmark 2022 decision in New York State Rifle & Pistol Association v. Bruen.
The majority opinion applied the Bruen standard, which requires that modern gun restrictions align with "this nation's historical tradition of firearm regulation," as the Washington Examiner reported. Under that test, the government bears the burden of showing that a challenged firearms law fits within a recognized historical pattern of regulation. New Jersey could not clear that bar for either its assault weapons ban or its magazine capacity limit.
The decision goes further than a July 2024 lower court ruling that had addressed the same statutes. That earlier ruling struck down portions of the law, but the Third Circuit's opinion invalidates both the assault weapons ban and the large-capacity magazine restriction in full, AP News reported.
Five judges dissented. The split reflects the deep divide among federal judges over how far Bruen reaches and whether its historical-tradition test leaves room for modern restrictions on weapons that did not exist at the founding.
No federal appeals court had previously struck down a state assault weapons ban. Several circuits have considered challenges to similar laws in recent years, and most upheld the restrictions, often under pre-Bruen frameworks that gave legislatures wide latitude to regulate firearms deemed especially dangerous. The Third Circuit's ruling breaks that pattern and creates a direct circuit split that increases pressure on the Supreme Court to resolve the question.
The timing is no accident. The high court is already set to consider whether bans on semiautomatic rifles violate the Second Amendment, a question the justices have so far declined to take up directly. The Third Circuit's decision gives the court a fresh and forceful data point from a major appellate bench. The Supreme Court recently struck down a Hawaii gun law in a ruling that drew sharp dissents from liberal justices, signaling the conservative majority's willingness to keep expanding Second Amendment protections.
John Commerford, executive director of the NRA Institute for Legislative Action, did not hold back. In a statement carried by Newsmax, Commerford called the ruling a vindication of core constitutional rights.
"The Third Circuit has struck down these unconstitutional so-called assault weapons bans and magazine bans in New Jersey, affirming what we've always known: the right to keep and bear arms, including commonly-owned rifles and standard-capacity magazines, is fundamental and cannot be infringed by politicians who prioritize control over constitutional freedoms."
Commerford also described the outcome as a "historic victory for the NRA, the Second Amendment, and law-abiding Americans." The organization had backed the legal challenge and framed the case as a test of whether Bruen would be applied with teeth or treated as a paper tiger by lower courts.
UCLA law professor Adam Winkler, a prominent scholar of firearms law, told AP News that the ruling's implications stretch well beyond New Jersey.
"What this Third Circuit opinion shows is that there are very few gun laws that are safe from being struck down right now."
That assessment reflects a growing consensus among legal observers on both sides of the debate: Bruen has fundamentally shifted the ground beneath state firearms regulation. Laws that survived challenge for years under older judicial tests now face a much steeper climb. The historical-tradition framework demands that the government produce evidence of analogous restrictions from the founding era or the period surrounding the Fourteenth Amendment's ratification. For modern weapons categories like semiautomatic rifles, that evidence is thin.
The Trump Department of Justice has leaned into this shift aggressively. The administration has filed Second Amendment lawsuits against several blue states, including a recent suit against Virginia over its assault weapons ban. The DOJ also filed a federal lawsuit against California over its Glock ban, pressing the argument that states cannot single out commonly owned firearms for prohibition.
New Jersey's attorney general has not yet announced whether the state will seek en banc rehearing before the full Third Circuit or petition the Supreme Court directly. Either path would extend the legal fight by months, possibly years. In the meantime, the status of the invalidated laws remains uncertain. Courts sometimes stay their rulings pending appeal, which would keep the bans in effect while the case moves forward.
Investigators of the legal landscape will also watch how other circuits respond. The Fourth, Seventh, and Ninth Circuits all have pending challenges to similar state bans. If those courts reach different conclusions, the resulting circuit split would make Supreme Court review all but inevitable.
The ruling arrives during a Supreme Court term that has already delivered First Amendment victories that drew fury from liberal justices. Gun rights advocates see the current judicial environment as the most favorable in a generation and are pressing cases on multiple fronts to lock in gains before the court's composition changes.
Fox News reported the ruling as a landmark moment for Second Amendment jurisprudence, and Breitbart characterized it as the first federal appeals decision to reject a state assault weapons ban outright. Both descriptions are accurate. No prior appellate court had gone this far.
The decision also tests a theory that gun control advocates have relied on for decades: that legislatures can ban entire categories of firearms if they deem those weapons particularly dangerous. The Third Circuit's majority rejected that premise, at least as applied to AR-15-style rifles and standard-capacity magazines, finding no sufficient historical analog to justify the prohibition.
For gun owners in New Jersey and across the country, the practical question is whether this ruling survives. For state legislators considering new firearms restrictions, the practical question is whether Bruen leaves them any room to act. The Trump administration has made clear, through its own aggressive litigation strategy across multiple legal fronts, that it intends to press the advantage.
When a federal appeals court tells a state that its gun ban fails constitutional muster for the first time in American history, the message is hard to miss. The only question left is whether the Supreme Court will agree.
