A federal appeals court has invalidated two of New Jersey’s most prominent gun restrictions: the state’s ban on a broad category of semiautomatic rifles (often labeled “assault firearms”) and its restriction on magazines capable of holding more than 10 rounds. The decision came from the U.S. Court of Appeals for the Third Circuit sitting en banc, meaning a larger group of judges heard the case rather than the usual three-judge panel.
The case itself also reflects a broader constitutional shift. In recent years, the Supreme Court has pushed lower courts toward a history-focused test for evaluating modern firearms restrictions. That framework is now driving outcomes across the country, including in this New Jersey dispute.

What the court struck down
The Third Circuit concluded that New Jersey’s restrictions violated the Second Amendment in two key ways:
- Semiautomatic rifle ban: The court held New Jersey’s “assault firearm” prohibition was unconstitutional as applied to the full class of semiautomatic rifles covered by the law, not only the AR-15 platform.
- Magazine restriction: The court also struck down the state’s restriction on magazines capable of holding more than 10 rounds.
Procedurally, the ruling did more than simply affirm what came before. The Third Circuit expanded a lower court’s ruling on the semiautomatic rifle ban to cover the full class of rifles covered by the law, and it reversed the district court’s decision upholding the state’s magazine restriction.
Who brought the case
The lawsuit was brought and litigated by the National Rifle Association, which has been in court over the New Jersey restrictions since 2018. After the ruling, the NRA called the decision a “historic victory” and described it as a major win for gun owners.
The framework behind the decision
To understand why this case turned out the way it did, it helps to know the modern Supreme Court “map” for Second Amendment cases. The Third Circuit pointed to three milestones:
- District of Columbia v. Heller (2008): Recognized an individual right to keep and bear arms, tied to self-defense, and rejected the idea that the Second Amendment protects only militia service.
- New York State Rifle & Pistol Association v. Bruen (2022): Replaced the balancing tests many lower courts used with a history-and-tradition approach .
- Subsequent Second Amendment cases: Reinforced that courts should use ordinary constitutional analysis, not special, watered-down standards for gun rights.
Writing for the majority, U.S. Circuit Judge Arianna Freeman said those Supreme Court decisions and later cases require governments to show modern firearm restrictions are consistent with America’s historical tradition of firearm regulation. Applying that framework, the court concluded New Jersey failed to meet that burden.
Why “common use” matters
One recurring theme after Heller and Bruen is the difference between arms that are unusual and arms that are commonly owned by law-abiding people. The Third Circuit majority concluded that semiautomatic rifles and magazines capable of holding more than 10 rounds are protected by the Second Amendment. That necessarily implies the court saw them as falling on the protected side of that line.
That does not mean every firearm, every accessory, or every manner of carrying is automatically protected. It means that when a state bans or restricts items that many ordinary citizens possess for lawful purposes, the state should expect a demanding constitutional inquiry under the history-and-tradition test.
New Jersey’s rationale, and the court’s answer
New Jersey’s “assault firearms” law dates back to 1990. The opinion noted the law was enacted following a California elementary school shooting. The record also included political context from that period, including the governor at the time describing the targeted firearms as “guns capable of wholesale destruction” that were “designed to wipe out the greatest number of people in the shortest possible time.”
Those statements reflect a familiar legislative impulse: identify weapons viewed as especially dangerous and remove them from civilian circulation.
But under the Supreme Court’s current approach, the debate cannot end with modern judgments about danger. The constitutional inquiry asks a different question: Is this kind of restriction rooted in an American historical tradition of firearm regulation?
The Third Circuit’s answer was no. The court concluded New Jersey did not carry its burden of showing that banning this class of semiautomatic rifles and restricting magazines capable of holding more than 10 rounds aligns with historically accepted limits on the right to keep and bear arms.
What this does and does not mean
When a court strikes down a gun law, it can sound like the judiciary has declared an unlimited right to own any weapon under any circumstances. That is not what the Supreme Court has said, and it is not what lower courts are supposed to do.
What the Second Amendment clearly protects
- An individual right to keep and bear arms.
- Core lawful purposes, with self-defense at the center of modern doctrine.
- Arms in common lawful use, which courts often treat as a strong signal of constitutional protection.
What still can be regulated
- Who can possess firearms in some contexts (for example, longstanding restrictions for certain categories of people have often been upheld, though the exact boundaries are contested).
- Where firearms can be carried, especially in certain “sensitive places,” so long as the restrictions fit within the post-Bruen historical analysis.
- How firearms are sold and stored, depending on the details and historical analogues.
The key shift is not that regulation disappears. It is that regulation must be justified in a way the Supreme Court recognizes. Many modern public-safety arguments are being re-litigated through a historical lens, and states are increasingly required to show their work.
Why the dissents matter
Not every judge agreed. Several dissents argued that the banned firearms are unusually dangerous military-style weapons, that states have long had authority to regulate them, and that the Third Circuit’s decision conflicts with every other federal appeals court to uphold similar state restrictions.
For readers, dissents are useful not because they “lose,” but because they preview what the next round of arguments will look like. When appellate courts split on major constitutional questions, the Supreme Court is more likely to step in, if the issue is presented cleanly and the timing is right.
What happens next
Three things are worth watching after an en banc ruling like this:
- Further appeals: New Jersey can seek Supreme Court review.
- Practical implementation: How quickly the decision changes enforcement on the ground can depend on the court’s mandate and any additional procedural steps.
- Copycat litigation: Challenges to similar bans in other states often accelerate when a federal appellate court issues a detailed, precedential ruling.
If you are trying to make sense of the bigger picture, here is the simplest takeaway: after Bruen, courts are asking governments to justify modern firearms restrictions by pointing to historical tradition, not by weighing costs and benefits the way legislatures do. That method is reshaping Second Amendment law in real time, case by case.
Quick FAQ
Did the court only protect AR-15s?
No. The Third Circuit’s ruling reached beyond a single model and treated New Jersey’s “assault firearm” law as a ban that covered a broader class of semiautomatic rifles.
Is this a nationwide ruling?
It is binding precedent within the Third Circuit’s jurisdiction. It can be persuasive elsewhere, and it can matter a great deal if the Supreme Court takes a similar case.
Does “history and tradition” mean only 1791 matters?
The Supreme Court has emphasized the founding era as a key reference point, and it allows some historical comparison across periods. But the core idea is consistent: modern gun restrictions need a credible historical analogue, not simply a modern policy justification.
