Historic Third Circuit Ruling Strikes Down New Jersey’s Assault Weapons and Magazine Ban — Here’s What It Means for Illinois

A federal appeals court just made history. Here’s what happened, why it matters, and what Illinois gun owners need to know right now.

The Third Circuit’s July 17, 2026 decision is the first time any federal appeals court has struck down a state assault weapons ban — reshaping the national legal landscape.

▶ At a Glance: What You Need to Know in 60 Seconds•  What happened: On July 17, 2026, the Third U.S. Circuit Court of Appeals struck down New Jersey’s ban on semiautomatic rifles and magazines holding more than 10 rounds — ruling both unconstitutional.•  Why it’s historic: This is the first time any federal appeals court has struck down a state-level assault weapons ban — a landmark moment in Second Amendment law.•  The vote: 10–5, decided “en banc” (meaning every active judge on the court heard the case together, not just a standard 3-judge panel).•  The legal test used: The Bruen test — a 2022 U.S. Supreme Court standard requiring gun laws to match America’s historical tradition of firearm regulation.•  Illinois impact: Illinois’ own ban — the Protect Illinois Communities Act (PICA)remains fully in effect. But this ruling dramatically increases pressure on the U.S. Supreme Court to step in and set a national rule.

At C.O.P.S., Inc., we stay on top of every major development in Second Amendment law — because the legal landscape directly affects you, our customers, and our community. Yesterday’s ruling out of the Third Circuit is one of the biggest Second Amendment decisions in years, and we want to break it down for you in plain language. No legalese. No politics. Just the facts and what they mean for responsible gun owners right here in Illinois.

Background: What Was New Jersey’s Law?

To understand why yesterday’s ruling is such a big deal, you need to know what was actually struck down.

New Jersey’s Assault Firearms Act has been on the books since 1990. It banned possession of dozens of specifically named semiautomatic rifles, pistols, and shotguns — plus any firearm the state considered “substantially identical” to those listed. Think of it as a broad prohibition on a whole category of commonly owned firearms.

Then in 2018, New Jersey went further — reducing the maximum lawful magazine capacity (the number of rounds a magazine can hold) from 15 rounds down to 10 rounds. Under that law, owning a standard-capacity magazine that holds more than 10 rounds was a serious crime:

●      Up to 10 years in prison

●      Fines up to $150,000

The only people exempt were a narrow group of collectors and sport shooters who had registered their firearms before the original law took effect and obtained a special state-issued license. For everyone else — including law-abiding citizens who relied on these firearms and magazines for home defense — it was a flat-out ban.

Who Brought the Case — and Why?

The legal challenge was brought by a coalition of plaintiffs who argued that both laws — the assault firearms ban and the magazine restriction — violated the Second Amendment to the U.S. Constitution. The key players were:

●      The Association of New Jersey Rifle and Pistol Clubs (ANJRPC) — a statewide gun rights organization

●      The Firearms Policy Coalition (FPC) — a national Second Amendment advocacy group

●      Individual gun owners affected by both laws

Their core argument was straightforward: millions of Americans lawfully own these exact firearms and magazines for self-defense and other legal purposes. Because these items are in widespread, common, lawful use, the government cannot simply ban them outright — any more than it could ban any other commonly owned firearm.

This case had a long legal history, with challenges starting years ago and gaining renewed momentum after the U.S. Supreme Court issued its landmark 2022 ruling in Bruen — which changed the entire framework for how courts must evaluate gun laws.

What Is the Bruen Test? (Plain Language Explanation)

This is the key concept that drives the entire case — and frankly, most major Second Amendment litigation happening right now across the country.

In 2022, the U.S. Supreme Court decided New York State Rifle & Pistol Association v. Bruen. That decision fundamentally changed the rules.

Before Bruen: The Old Test

Before Bruen, courts used what’s called a “means-end” balancing test. Basically, a court would weigh the government’s interest in public safety against how much a law burdened gun rights — and the government almost always won. Most gun bans survived under that approach.

After Bruen: The New “Text and History” Test

The Supreme Court threw out that old test entirely. Under the new Bruen test, the government must now prove that a modern gun restriction is consistent with America’s historical tradition of firearm regulation — meaning the government has to find a comparable law that existed during the Founding era (the 1700s and early 1800s).

📚 Bruen Test: The Simple VersionIf the government can’t point to a historical analog — a similar law from the era when the Second Amendment was ratified — the modern restriction is unconstitutional. Period. The government can no longer simply argue that a law is a good idea for public safety.

This test has been reshaping Second Amendment cases in courtrooms across the entire country ever since 2022 — and it’s the engine behind the New Jersey ruling.

What Did the Third Circuit Actually Rule?

The Third U.S. Circuit Court of Appeals — based in Philadelphia and covering New Jersey, Pennsylvania, Delaware, and the U.S. Virgin Islands — heard this case en banc. That’s a legal term meaning all of the court’s active judges heard it together, rather than the standard three-judge panel. This is reserved for the most significant cases and signals the court viewed this as exceptionally important.

The vote: 10 judges in favor of striking down the laws, 5 judges dissenting (disagreeing).

What the Majority Found

The majority opinion was authored by Judge Arianna J. Freeman. The court’s key conclusions:

●      Semiautomatic rifles covered by New Jersey’s law are in “common use” for lawful purposes by millions of Americans — and are therefore protected by the Second Amendment under the framework established in the Supreme Court’s 2008 Heller decision and Bruen.

●      Magazines capable of holding more than 10 rounds are also “arms” within the meaning of the Second Amendment and are similarly protected.

●      New Jersey failed to show that either restriction is consistent with America’s historical tradition of firearm regulation. The government simply could not find historical laws comparable enough to justify these modern bans.

This Ruling Went Further Than Expected

Notably, the Third Circuit’s ruling went further than a 2024 lower court ruling in the same case — which had only struck down the AR-15 ban but upheld the magazine restriction. The Third Circuit struck down both the assault weapons ban and the magazine limit.

Additionally, the court directed the lower court to examine whether the assault weapons ban is unconstitutional as applied to other types of firearms — including semiautomatic pistols and shotguns — not just rifles.

“As unfortunate as it is legally incorrect.”— New Jersey Attorney General Jennifer Davenport, responding to the ruling and stating the state is “considering its options.”

Why This Is a Huge Deal: The Circuit Split

Here’s why every gun owner, attorney, and lawmaker in America is paying close attention to this ruling.

Before July 17, 2026, every federal appeals court that considered a state-level assault weapons ban had upheld it. The Third Circuit just became the first to go the other direction — striking one down. This creates what lawyers call a “circuit split.”

⚠ What Is a Circuit Split?The United States is divided into 13 federal appeals circuits. When two or more circuits reach opposite conclusions on the same legal question, that’s a “circuit split.” It means the law is being applied differently depending on where you live — which is fundamentally unfair. The U.S. Supreme Court typically steps in to resolve circuit splits and create a single, uniform national rule.

The timing of this split is striking. Just one week earlier — on July 9, 2026 — the 7th U.S. Circuit Court of Appeals (which covers Illinois, Indiana, and Wisconsin) upheld Illinois’ assault weapons ban 2–1 in Harrel v. Raoul, going in the exact opposite direction from the Third Circuit.

Two federal appeals courts. One week apart. Opposite outcomes. The Supreme Court now has a clear reason — and arguably an obligation — to step in.

Where Illinois Stands Right Now

This is the section Illinois gun owners need to read most carefully.

What Is PICA?

Illinois’ law — the Protect Illinois Communities Act (PICA) — was signed by Governor JB Pritzker in January 2023 in the aftermath of the July 4, 2022 Highland Park parade mass shooting. PICA prohibits:

●      The sale, transfer, and new acquisition of firearms classified as “assault weapons,” including many semiautomatic rifles with certain features

●      High-capacity magazines exceeding:

○      10 rounds for long guns (rifles and shotguns)

○      15 rounds for handguns

●      Certain accessories and attachments

The 7th Circuit Upheld PICA — Just 8 Days Ago

On July 9, 2026 — just eight days before the New Jersey ruling — the 7th Circuit upheld PICA 2–1 in Harrel v. Raoul. The majority found the law “consistent with the principles that underpin our nation’s tradition of firearm regulation.” Chief Judge Michael Brennan dissented sharply, arguing the majority had misapplied the Bruen test.

Current Status at a Glance

⚠ Important: The NJ Ruling Does NOT Change Illinois LawThe Third Circuit’s ruling applies only to New Jersey (and technically only in the Third Circuit’s jurisdiction). PICA remains fully in effect in Illinois today. Do not assume this ruling changes what you can legally buy, possess, or sell in Illinois.

What Does This Mean for Illinois Gun Owners? Practical Guidance

We know this is a rapidly changing situation, and we want to give you clear, practical guidance based on where the law stands today:

●      PICA is still the law in Illinois. Do not assume the New Jersey ruling changes what you can buy, sell, or possess here. It does not — at least not yet.

●      If you legally owned a regulated firearm or magazine before January 10, 2023, and you filed your PICA affidavit on time, you may continue to possess it under the law’s restrictions — but you cannot sell or transfer it within Illinois to a private party.

●      New purchases of banned firearms or magazines remain prohibited under Illinois law for civilians in the general public.

●      Law enforcement, military personnel, and certain first responders have exemptions under PICA — but those exemptions apply within the scope of official duty. Always confirm your specific situation with your agency’s legal counsel.

●      Watch for rapid updates. The legal landscape is moving faster right now than it has in years. The NJ ruling creates serious pressure for the Supreme Court to step in and set a national standard — and that decision, when it comes, will likely determine the future of PICA.

The Supreme Court: The Final Word Is Coming

Here’s the big picture — and frankly, the reason for real optimism among Second Amendment advocates.

The U.S. Supreme Court has already agreed to hear two major assault weapons cases:

●      Viramontes v. Cook County — a direct challenge to Cook County, Illinois’ own assault weapons ban. Oral arguments are expected during the Court’s fall 2026 term.

●      Grant v. Connecticut — a challenge to Connecticut’s assault weapons ban.

A Supreme Court decision in one or both of those cases will almost certainly set the national standard and determine the future of Illinois’ PICA law. If the Court rules that these bans are unconstitutional under the Bruen test, PICA — and every similar law in the country — would fall.

“The Third Circuit’s opinion may be foretelling the Supreme Court’s coming opinion on assault weapons bans… There are very few gun laws that are safe from being struck down right now.”— Adam Winkler, UCLA School of Law Professor and Second Amendment legal scholar

Legal experts widely note that the Third Circuit’s 10–5 ruling — combined with the existing circuit split — gives the Supreme Court both the opportunity and the urgency to resolve this issue once and for all. The high court’s composition and its recent Heller and Bruen precedents suggest it may be receptive to striking down these bans nationally.
