Sierra Club v. Morton, 405 U.S. 727 (1972), is a Supreme Court of the United States case on the issue of standing under the Administrative Procedure Act. The Court rejected a lawsuit by the Sierra Club seeking to block the development of a ski resort at Mineral King valley in the Sierra Nevada Mountains because the club had not alleged any injury. The case prompted a famous dissent by Justice William O. Douglas suggesting that in response to ecological concerns, environmental objects (such as a valley, an alpine meadow, a river, or a lake) should be granted legal personhood by the public.
