Wolford v. Lopez
In Wolford v. Lopez, (2025), the U.S. Supreme Court rejected a Hawaiian law which prohibited people carrying firearms onto private property open to the public without express consent.
Background
Hawaii has, even before becoming the 50th state, a long tradition against public ownership of firearms. It has attempted on several occasions to pass laws in contradiction of the Second Amendment. The most recent one, the subject of the challenge, involved yet another such attempt.
Under English Common Law, the default rule is that if private property is open to the public (such as a retail establishment), any person may legally enter onto the property unless the property owner (or another having the right to control access, such as a lessee or a business manager) affirmatively denies such access.
