WASHINGTON — The U.S. Supreme Court agreed Tuesday to hear a pair of closely watched Second Amendment cases challenging bans on AR-15-style rifles and other semiautomatic firearms in Illinois and Connecticut, setting the stage for what could become the court’s most consequential gun rights decision since its landmark 2022 Bruen ruling.
The justices will review appeals involving Connecticut’s assault weapons ban and Cook County, Illinois’ prohibition on similar firearms. Together, the cases ask whether states may ban semiautomatic rifles that gun rights advocates argue are among the most commonly owned firearms in the United States.
Major Second Amendment Test
The court’s decision to grant review comes after years of declining to take up similar challenges.
The central legal question is whether AR-15-platform rifles and similar semiautomatic firearms are protected by the Second Amendment because they are “in common use” for lawful purposes such as self-defense, hunting, and recreational shooting.
Gun rights organizations argue that millions of Americans legally own these rifles, placing them squarely within the constitutional protections recognized in District of Columbia v. Heller and expanded in New York State Rifle & Pistol Association v. Bruen.
States Defend Public Safety Laws
Illinois, Connecticut, and gun control advocates contend the laws are constitutional because they regulate firearms they characterize as especially dangerous and frequently used in mass shootings.
Connecticut enacted its restrictions following the 2012 Sandy Hook Elementary School shooting, while Illinois adopted its statewide ban after the 2022 Highland Park Independence Day parade attack. Supporters argue the laws are consistent with historical firearm regulations and are necessary to protect public safety.
Ruling Could Reshape Gun Laws Nationwide
The Supreme Court’s decision could have implications far beyond Illinois and Connecticut.
Several states — including California, New York, Maryland, New Jersey, Massachusetts, Delaware, and Washington — have enacted similar restrictions on semiautomatic rifles and large-capacity magazines. A ruling striking down the challenged laws could trigger new legal challenges to those statutes.
Conversely, a decision upholding the bans would provide states with stronger constitutional footing to maintain or adopt comparable restrictions.
Court Continues Expanding Second Amendment Docket
The cases arrive as the Supreme Court has shown increasing interest in clarifying the scope of the Second Amendment.
In recent weeks, the court has issued several decisions strengthening gun rights protections, including rulings involving firearm ownership and public carry. The semiautomatic rifle cases are expected to provide the justices with an opportunity to address one of the nation’s most contentious unresolved constitutional questions.
Arguments Expected This Fall
The consolidated cases will be argued during the Supreme Court’s next term, with a decision expected by the end of the term in 2027.
Because the ruling could determine whether commonly owned semiautomatic rifles receive full constitutional protection, legal observers expect it to become one of the most closely watched Second Amendment decisions in decades.
