Federal Court Strikes Down New Jersey Ban on Assault Rifles and Large-Capacity Magazines

A common misconception regarding the modern legal battle over firearms is that state-level bans on semiautomatic rifles are uniformly surviving federal scrutiny. While appellate courts have recently upheld such restrictions in several jurisdictions, the judicial consensus has officially fractured. In a landmark 10-5 en banc decision, the Third U.S. Circuit Court of Appeals struck down New Jersey’s decades-old prohibition on "assault firearms" and large-capacity magazines, marking the first time a federal appellate court has invalidated a state assault weapons ban on Second Amendment grounds.[1][3]

The ruling, handed down in mid-July, immediately threw one of the nation’s strictest gun control regimes into uncertainty. The decision stemmed from a lawsuit spearheaded by the Association of New Jersey Rifle & Pistol Clubs, which challenged the state's comprehensive restrictions on AR-15-style rifles and magazines capable of holding more than 10 rounds. The appellate court's sweeping judgment went significantly further than a 2024 lower-court ruling, which had struck down the ban specifically on Colt AR-15s but upheld the broader prohibition and the magazine capacity limits.[2]

At the core of the Third Circuit’s decision is the Supreme Court’s 2022 ruling in New York State Rifle & Pistol Association v. Bruen. That precedent established that modern gun regulations must align with the nation’s "historical tradition of firearm regulation" rather than relying on contemporary interest-balancing tests. Writing for the majority, U.S. Circuit Judge Arianna J. Freeman—a Biden appointee—concluded that semiautomatic rifles and large-capacity magazines are commonly owned for lawful purposes by millions of Americans, citing estimates that roughly 24 million AR-15-style rifles are currently in circulation nationwide.[1][3]

Judge Freeman acknowledged the societal concern regarding the misuse of weapons to harm others, noting that such concerns have persisted since the 18th century. However, she reasoned that because the Founders did not adopt similar broad prohibitions to address the problem, New Jersey’s ban lacks a sufficient historical analog. "Even if we agreed that semiautomatic rifles implicate unprecedented societal concerns or dramatic technological changes, that would not change the outcome here," Freeman wrote, emphasizing that the court is bound by the historical framework mandated by the Supreme Court.[1]

The decision drew strong support from gun rights advocates, who celebrated the invalidation of a law they view as an infringement on fundamental rights. In a concurring opinion, U.S. Circuit Judge Paul B. Matey wrote that the ruling "returns the Second Amendment to its appropriate place in our constitutional design," describing it as a welcome step to end the anxiety imposed on millions of New Jersey residents. Advocacy groups praised the court for recognizing that everyday gun owners utilize these firearms for lawful self-defense, target shooting, and hunting.[1][2]

Conversely, the five dissenting judges and state officials argued that the restrictions are entirely consistent with historical laws regulating weapons considered unusually dangerous. Dissenting Judge Patty Shwartz wrote that the majority improperly adopted a contemporary lens rather than the historical one required by Bruen. New Jersey Attorney General Jennifer Davenport, whose office defended the law, called the decision "as unfortunate as it is legally incorrect." Davenport emphasized that assault weapons and large-capacity magazines play a uniquely dangerous role in the modern epidemic of mass shootings, arguing that the state acted reasonably in restricting them.[3]

The legal landscape shifted again on August 4, when the Third Circuit issued a stay on its own decision. This administrative pause ensures that New Jersey’s restrictions remain fully in effect while the state petitions the U.S. Supreme Court for review. Davenport welcomed the stay, stating that it provides "much-needed stability on the ground" and ensures the 36-year-old law remains enforceable as the litigation continues. For now, New Jersey residents cannot lawfully purchase or possess the contested firearms or magazines, and law enforcement will continue to enforce the existing statutes.

The Third Circuit’s ruling creates a direct and undeniable conflict with other federal appellate courts, effectively guaranteeing Supreme Court intervention. The Fourth and Seventh Circuits have previously upheld similar bans in Maryland and Illinois, respectively, reasoning that assault weapons are akin to military hardware and thus fall outside Second Amendment protections. This circuit split places the constitutionality of bans in 11 states and the District of Columbia in immediate jeopardy, setting the stage for a definitive national showdown over the limits of state-level gun control.

The immediate ripple effects of the decision will be felt most acutely within the Third Circuit's jurisdiction. Legal analysts note that Delaware’s assault weapons ban, enacted in 2022 following mass shootings in Uvalde and Buffalo, is likely the next to fall. A district court judge currently hearing an unresolved challenge to Delaware's ban will be bound by the appellate court’s new precedent, potentially dismantling the state's restrictions. The decision could also affect similar prohibitions in the U.S. Virgin Islands, which falls under the same appellate umbrella.

The ultimate resolution now rests with the Supreme Court, which is already poised to address the issue. The justices have agreed to hear challenges to assault weapons bans in Illinois and Connecticut during their upcoming term. Legal experts suggest the Third Circuit’s decision could heavily influence the high court’s framework for applying the Bruen test to semiautomatic rifles. Until the justices issue a definitive ruling, the national legal battle over assault weapons remains deeply fractured, with millions of gun owners and advocates awaiting a final constitutional verdict.
