In the state legislature's first session, under Haskell's leadership, Oklahoma adopted laws regulating banking in the state, reformed the old territorial prison system, and protected the public from exploitative railroads, public utilities, trusts and monopolies. Haskell also initiated a law insuring deposits in case of a bank failure, a landmark piece of legislation in the nation. Haskell also rigidly enforced prohibition through the Alcohol Control Act. Though following progressive dogma at every turn, such as the introduction of child labor laws, factory inspection codes, safety codes for mines, health and sanitary laws, and employer's liability for workers, Haskell's legislative schedule also included Jim Crow laws for Oklahoma. Haskell's other significant contributions while governor included establishing the Oklahoma Geological Survey, the Oklahoma School for the Blind, the Oklahoma College for Women and the Oklahoma State Department of Health. In addition, he helped to create the Oklahoma Court of Criminal Appeals in 1908. Haskell selected the first judges of the Oklahoma Court of Criminal Appeals.
