The US Supreme Court has struck down a 2023 Hawaii law that required gun owners to obtain explicit permission before carrying firearms into privately owned businesses such as shops and hotels. The 6-3 ruling means people may now carry guns onto private commercial property by default, unless owners post notices specifically prohibiting them — overturning what critics nicknamed the "vampire rule" due to its invitation-based entry requirement. The decision is the latest in a series of Second Amendment rulings since the court's landmark 2022 finding that most Americans have the right to carry guns in public, and is seen as a victory for the Trump administration, which had backed the legal challenge brought by a gun rights group and three Maui residents.
