A federal judge has ruled that New Jersey's ban on AR-15 rifles is unconstitutional, marking a significant challenge to the state's gun control measures. Judge Peter Sheridan cited the Second Amendment and the Supreme Court's 2022 Bruen ruling, which prohibits categorical bans on firearms commonly used for self-defense. However, he upheld the state's restrictions on large-capacity magazines, indicating that while the ruling favors gun rights advocates, it does not extend to other banned firearms. New Jersey Attorney General Matthew Platkin plans to appeal the decision, arguing that the law was designed to protect residents from gun violence. The legal landscape remains contentious, with both sides preparing for further challenges. Meanwhile, in Jackson County, a proposed ordinance to restrict firearm possession for those under 21 is deemed illegal, prompting warnings of potential lawsuits from county officials.
