Illinois will defend its 2023 law banning certain semi‑automatic firearms and high‑capacity magazines before the Seventh Circuit U.S. Court of Appeals this Monday. The law, signed by Governor J.B. Pritzker, was declared unconstitutional last year by a federal district court, which found that banning commonly owned firearms violates the Second Amendment. The state and its supporters contend the law targets “dangerous and unusual” weapons amid growing concerns over mass shootings.
