A federal appeals court upheld Illinois' ban on semiautomatic weapons, reversing a lower court decision that had blocked the law. The Seventh Circuit Court of Appeals ruled that the state's prohibition on assault-style rifles and high-capacity magazines passes constitutional scrutiny under the Second Amendment.

Illinois enacted the Firearms Restraint Act in 2023, making it illegal to possess, sell, or transfer semiautomatic rifles and shotguns with certain features, along with magazines holding more than 10 rounds. A federal judge initially blocked enforcement of the law, arguing it violated Second Amendment rights established in the 2022 Supreme Court decision New York State Rifle and Pistol Association v. Bruen.

The appeals court disagreed. The three-judge panel found that Illinois demonstrated a compelling governmental interest in regulating weapons used in mass shootings and other violent crimes. The court applied the framework from the Bruen decision, which requires states to show that firearm restrictions align with historical tradition and serve a substantial interest.

This ruling clears the path for enforcement of one of the nation's strictest gun laws. Illinois joins California, Connecticut, New York, and other states in banning semiautomatic weapons. The decision carries major implications for similar laws facing legal challenges across the country.

Gun rights groups like the National Rifle Association oppose the ban and have signaled intent to pursue further appeals, potentially seeking review by the Supreme Court. Illinois Democrats, who championed the law, view the ruling as validation of their public safety approach. Republican opponents argue the ban infringes on constitutional rights.

The Seventh Circuit's decision conflicts with rulings from other appeals courts that have struck down comparable restrictions, creating a split that could prompt Supreme Court intervention. Legal experts expect the justices will eventually address whether such comprehensive semiautomatic bans survive Bruen's test, making this case a pivotal moment in
