EVENT / SOURCE PERIOD: Review granted 30 June 2026; argument 2 December 2026
What the Court agreed to decide
On June 30, 2026, the Supreme Court agreed to hear two consolidated challenges to bans on semi-automatic rifles: Viramontes v. Cook County, from the Seventh Circuit, and Grant v. Higgins, a challenge to Connecticut’s law from the Second Circuit. The question, as framed in the Viramontes petition, is whether the Second and Fourteenth Amendments guarantee the right to possess AR-15 platform and similar semi-automatic rifles.
The justices have set aside one hour for argument on the morning of December 2, 2026. A decision would normally be expected by the end of the term in late June or early July 2027. Granting review does not change any law in the meantime; the Cook County and Connecticut bans remain in force.
How the case got here
The Seventh Circuit upheld Cook County’s ordinance, saying it was bound by its own earlier precedent sustaining the same law. The Court had repeatedly declined similar cases in recent terms, including Maryland’s ban in 2025, before taking up these two.
The pressure for a national answer grew after the grant. On July 9, 2026, the Seventh Circuit upheld Illinois’s statewide ban. Eight days later, the full Third Circuit struck down New Jersey’s rifle and magazine limits by a 10–5 vote, a ruling that has since been paused. Federal appeals courts are now openly divided.
The arguments
The challengers filed their main brief on August 28. They argue that AR-15-style rifles are among the most commonly owned rifles in the country and are kept for lawful purposes such as self-defense, which under the Court’s 2022 Bruen decision makes them presumptively protected. Tennessee, Kansas and 25 other states filed a brief supporting them.
Cook County and Connecticut have filed merits briefs defending their laws. Their side, supported by gun-safety groups, argues that legislatures may restrict weapons they consider especially dangerous and suited to mass-casualty attacks, and that the history of regulating dangerous weapons supports the bans.
Afterlight analysis: what to watch
Three questions are likely to shape the outcome. First, how the Court measures whether a weapon is in “common use.” Second, whether a ban on a category of rifles can be justified by historical laws aimed at other weapons. Third, whether any ruling reaches magazines, which the New Jersey case also involves but which the question presented does not name.
A ruling for the challengers would put rifle bans in roughly a dozen jurisdictions in doubt. A ruling for the governments would likely end the wave of pending challenges to those laws. Either way, the December argument is the most consequential Second Amendment hearing since Bruen.
