The Supreme Court has agreed to take up a case that could determine whether bans on AR-15s and other semiautomatic rifles violate the Second Amendment, a question the justices sidestepped just weeks ago when they declined to hear a direct challenge to Maryland's semiautomatic rifle ban.

The move came as the Court wrapped its most recent term on Tuesday. It marks a potential turning point for gun-rights advocates who have waited years for the justices to weigh in on a class of firearms owned by millions of Americans.

The Court will hear appeals challenging assault weapons bans in Connecticut and the Chicago area, AP News reported. Arguments are expected in the fall. A ruling against those bans could invalidate similar laws in roughly a dozen states, covering major cities including New York, Los Angeles, and Washington, D.C.

From dodge to docket

The decision to grant certiorari arrives against a revealing backdrop. In June 2025, the Court declined to hear Snope v. Brown, a case that directly challenged Maryland's semiautomatic rifle ban. The Fourth Circuit had upheld that ban, reasoning that AR-15s are not "arms" protected by the Second Amendment.

Justice Clarence Thomas was not content to let the matter rest. He filed an eight-page dissent from the denial of certiorari in Snope v. Brown (Case No. 24-203), laying out his position in blunt terms:

"This petition presents the question whether this ban is consistent with the Second Amendment. The Fourth Circuit held that it is, reasoning that AR, 15s are not 'arms' protected by the Second Amendment... I would grant certiorari to review this surprising conclusion."

That the Fourth Circuit concluded one of the most widely owned rifle platforms in the country does not qualify as a constitutionally protected "arm" was, in Thomas's view, a conclusion that demanded the Court's attention. The Court passed on that opportunity in June. Now it has accepted a different vehicle to address the same fundamental question.

The Court's willingness to revisit the issue so quickly after declining Snope suggests the justices found a case, or a set of cases, better suited to resolve the constitutional question. It also suggests that at least four justices believe the time has come to settle the matter. Under the Court's rules, four votes are required to grant certiorari.

Kavanaugh's signal

Justice Brett Kavanaugh had previously written that a denial of certiorari carries no substantive weight on the merits, and he telegraphed that the AR-15 question would not stay unresolved for long:

"A denial of certiorari does not mean that the Court agrees with a lower-court decision or that the issue is not worthy of review... in my view, this Court should and presumably will address the AR, 15 issue soon, in the next Term or two."

That language read like a promise. And now, within the timeframe Kavanaugh outlined, the Court has taken the case. The pattern of notable dissents from cert denials has become a reliable indicator of where the Court is heading, and Thomas and Kavanaugh made their direction plain.

Former U.S. Attorney Joyce Vance, writing on her Substack, raised concerns about the Court's decision to take the case. She framed the grant of certiorari as a warning sign for gun-control advocates:

"The Court doesn't take cases like this just to pat a state on the head and sign off on its ban, it has bigger fish to fry than affirming the status quo."

Vance also noted the uncertainty about the internal vote count, writing: "We don't know if the four Justices picked up a fifth vote along the way that convinced Justice Kavanaugh this was 'the right time.'"

A Court already moving on guns

The cert grant does not arrive in a vacuum. The Court has already backed Second Amendment rights twice this term, Newsmax reported, striking down gun-carry restrictions in Hawaii and a federal ban on gun ownership by marijuana users. Those decisions extended the logic of the Court's landmark 2022 ruling that expanded gun rights and required firearms regulations to be consistent with the nation's historical tradition of firearms regulation.

That 2022 framework has already led to the striking down of several other firearm restrictions across the country. An assault weapons ban case gives the Court a chance to apply that same framework to the most politically charged category of gun regulation in America.

The stakes are not abstract. Adam Kraut of the Second Amendment Foundation put the practical argument plainly: "The Second Amendment protects arms in common use for lawful purposes, and it's hard to argue that a type of rifle that potentially outnumbers Ford F-150 trucks in America doesn't meet that standard."

On the other side, Janet Carter of Everytown Law defended the bans: "These laws are critical public safety measures, and they are consistent with the Second Amendment." That argument will now face its most consequential test.

What's at stake in a dozen states

If the Court strikes down the Connecticut and Cook County bans, the ripple effects would be immediate. Similar assault weapons bans exist in roughly a dozen states. Laws in New York, California, New Jersey, Massachusetts, and the District of Columbia could all be vulnerable. Millions of residents in those jurisdictions would see their legal landscape shift overnight.

For gun-rights advocates, the case represents the logical next step after years of incremental victories. The Court has steadily expanded Second Amendment protections, and an assault weapons ban is the most significant remaining restriction that has not yet received a definitive ruling from the high court. This term has already produced major precedent-overturning decisions from the justices, and the AR-15 case could follow that pattern.

For gun-control advocates, the Court's willingness to take the case after years of declining similar petitions is itself a signal. The justices do not typically grant certiorari to affirm lower courts. They take cases to resolve circuit splits or to correct what they view as errors. Vance's reading, that the Court has "bigger fish to fry", reflects a widespread expectation among legal analysts on the left that the bans are in serious jeopardy.

The broader trajectory of the Court this term reinforces that concern. The justices have delivered consequential rulings across multiple areas of law, and the conservative majority has shown little hesitation in reaching questions that prior Courts avoided.

Open questions heading into the fall

Several important details remain unresolved. Which four justices voted to grant certiorari has not been disclosed. Whether Kavanaugh provided the critical vote, as Vance speculated, is unknown. The specific procedural posture of the Connecticut and Cook County cases, and how the Court chooses to frame the question presented, will shape the scope of any eventual ruling.

The Court's recent term also featured sharp internal divisions on other high-profile matters, including a 6-3 ruling on transgender athlete bans. How the justices align on the AR-15 question, and whether the ruling is broad or narrow, will determine whether the case reshapes gun law nationwide or leaves room for states to craft alternative restrictions.

Arguments are expected in the fall, with a decision likely by the end of the next term. Gun owners, state legislators, and law enforcement agencies across the country will be watching.

For millions of Americans who already own the rifles in question, the case is overdue. The Second Amendment either protects arms in common use or it doesn't, and the Court has finally agreed to say which.
