Hague v. CIO
HAGUE, MAYOR, ET AL. v. COMMITTEE FOR INDUSTRIAL ORGANIZATION ET AL was decided on June 5, 1939. It involved Jersey City, New Jersey Mayor Frank "Boss" Hague who had used a city ordinance to prevent labor meetings in public places and stop the distribution of literature pertaining to the CIOs cause. He referred to them as "communist."
District and circuit courts ruled in favor of the CIO which brought the suit against the mayor for these actions. Hague appealed to the Supreme Court which ruled against him and held that Hague's ban on political meetings violated the First Amendment right to freedom of assembly. The ordinances were voided by the court.
