Loewe v. Lawlor, 208 U.S. 274 (1908), also referred to as the Danbury Hatters' Case, is a United States Supreme Court case in US labor law concerning the application of antitrust laws to labor unions. The Court's decision effectively outlawed the secondary boycott as a violation of the Sherman Antitrust Act, despite union arguments that their actions affected only intrastate commerce. It was also decided that individual unionists could be held personally liable for damages incurred by the activities of their union.
