Sturgeon v. Frost

(United States Supreme Court) – Held that the National Park Service lacked authority to regulate boating on Alaska’s Nation River. A moose hunter contended that the Park Service could not ban him from using a hovercraft on a portion of the river that crossed a national preserve. Ruling in his favor, the U.S. Supreme Court explained that while the Park Service normally may establish rules for boating on waters within national parks, the Alaska National Interest Lands Conservation Act creates an Alaska-specific exception. Justice Kagan delivered the unanimous opinion.
