Hague v. Committee for Industrial Organization, 307 U.S. 496 (1939), is a US labor law case decided by the United States Supreme Court. Facts In Jersey City, New Jersey, Mayor Frank Hague had in 1937 used a city ordinance to prevent labor meetings in public places and stop the distribution of literature pertaining to the Committee for Industrial Organization's cause. He referred to the CIO as "communist." Judgment District and circuit courts ruled in favor of the CIO, which brought the suit against the mayor for these actions and which was represented by Morris L. Ernst, Spaulding Frazer, Lee Pressman and Benjamin Kaplan. 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, and so the ordinances were void.
