The U.S. Supreme Court has vacated a federal appeals court ruling that had granted individuals aged 18 to 20 the right to carry firearms in public during emergencies in Pennsylvania. The Supreme Court directed the Third Circuit to reconsider the case in light of its recent decision in Rahimi. This move effectively upholds Pennsylvania's law that restricts gun rights for individuals under 21, particularly during states of emergency. The case will now return to the Third Circuit for further review in light of the Rahimi decision.
