Friends of the Earth, Inc. v. Laidlaw Environmental Services, Inc., 528 U.S. 167 (2000), was a United States Supreme Court case that addressed the law regarding standing to sue and mootness. The Court held that the plaintiff residents in the area of South Carolina's North Tyger River had standing to sue an industrial polluter, against whom various deterrent civil penalties were being pursued. Standing was properly based on the fact that the residents alleged that they would have used the river for recreational purposes, but could not because of the pollution.
