In the United States, price controls have been enacted several times. The first time price controls were enacted nationally was in 1906 as a part of the Hepburn Act. In World War I the War Industries Board was established to set priorities, fix prices, and standardize products to support the war efforts of the United States. During the 1930s, the National Industrial Recovery Act (NIRA) created the National Recovery Administration, that set prices and created codes of "fair practices". In May 1935, the Supreme Court held that the mandatory codes section of NIRA were unconstitutional, in the court case of "Schechter Poultry Corp. v. United States".
