This case appears to be the first that the Supreme Court will hear since its ruling that involves the places where guns can be carried. Last year, however, the Supreme Court upheld a federal law that prohibits people who are subject to domestic violence restraining orders from having firearms. But Hawaii officials said the rule regarding private property "represents a permissible effort to vindicate the rights of Hawaii's citizens." "The Second Amendment protects 'an individual right to keep and bear arms for self-defense,'" Hawaii's lawyers wrote in a Supreme Court filing. Janet Carter, managing director of Second Amendment Litigation at Everytown Law, urged the Supreme Court to uphold the law.
