West Coast Hotel Co. v. Parrish, 300 U.S. 379 (1937), was a decision by the United States Supreme Court upholding the constitutionality of state minimum wage legislation. The court's decision overturned an earlier holding in Adkins v. Children's Hospital (1923) and is generally regarded as having ended the Lochner era, a period in American legal history during which the Supreme Court tended to invalidate legislation aimed at regulating business.
