Danbury Hatters' Case
Danbury Hatters' Case, decided in 1908 by the U.S. Supreme Court. In 1902 the hatters' union instituted a nationwide boycott of the products of a nonunion hat manufacturer in Danbury, Conn., and the manufacturer brought suit against the union for unlawfully combining to restrain trade in violation of the Sherman Antitrust Act. The Supreme Court held that the union was subject to an injunction and liable for the payment of treble damages. This precedent for federal court interference with labor activities was later modified by statutes.
