Two years later after President Roosevelt\'s overwhelming reelection in 1936 and discussion of judicial reform, the Supreme Court took up the issue of labor legislation again in "West Coast Hotel Co. v. Parrish" (1937) and upheld the constitutionality of minimum wage legislation enacted by Washington state and overturned the "Adkins" decision which marked the end of the "Lochner" era. In 1938, the minimum wage was re-established pursuant to the Fair Labor Standards Act, this time at a uniform rate of $0.25 per hour ().
