Supreme Court Agrees to Hear Major Challenge Against Assault Weapons Bans

The Supreme Court agreed on June 30, 2026, to hear challenges to assault weapons bans in Connecticut and Cook County, Illinois, according to NBC News. It marks the first time the court will directly rule on whether states can ban semiautomatic rifles like the AR-15.
The court's 6-3 conservative majority will hear the cases in its next term, with oral arguments expected in fall 2026 and a decision likely in 2027, CBS News reported. A ruling against the bans could invalidate similar laws in 14 states and the District of Columbia.
Connecticut first banned assault weapons in 1993. After the 2012 Sandy Hook shooting, which killed 26 people with an AR-15-style rifle, the state expanded the ban in 2013, according to CBS News. Cook County, Illinois, has had a similar ordinance since 1993. Its ban specifically prohibits 125 rifles by name or feature.
Both bans survived lower court challenges. The Second and Seventh Circuit Courts upheld them, ruling that semiautomatic rifles are not in "common use" for self-defense the way handguns are, Chicago Tribune reported. Gun rights groups pushed the cases to the Supreme Court after those losses.
The legal landscape shifted in June 2022 when the Supreme Court issued its ruling in NYSRPA v. Bruen. That decision set a new test: any gun law must match the "historical tradition" of firearm regulation from the 1700s and 1800s. Lower courts have struggled to apply that standard to modern semiautomatic rifles.
Legal analysts say the court's decision to take these cases signals that at least four justices believe the bans fail the Bruen test, according to NBC News. The Second Amendment Foundation's executive director, Adam Kraut, has argued that "bans like Connecticut's are in direct contradiction to the demands of the Constitution."
The core argument from challengers is simple: over 20 million AR-15-style rifles are in circulation in the U.S., according to NBC News. The 2008 Heller ruling protects guns "in common use" for lawful purposes. Gun rights advocates say that threshold is clearly met.
The National Association for Gun Rights led the Connecticut challenge, while Cutberto Viramontes is the lead plaintiff in the Cook County case. Gun control groups like Giffords counter that courts have repeatedly found such bans "critical to keeping our communities safe" and that these rifles pose a unique danger in mass shooting events.
If the Supreme Court strikes down the bans, it would immediately affect laws in 14 states and Washington, D.C., CBS News reported. States could also face lawsuits over past enforcement of laws later ruled unconstitutional. The decision is expected to land in late spring or early summer 2027.
The ruling will arrive in the middle of a heated political cycle. Both sides are already framing the case as a defining fight over public safety versus constitutional rights. The court took the cases just four days after striking down a Hawaii law restricting firearms on private property, signaling an active term on gun rights, according to Press Enterprise.
