State law in 1891 created a Municipal Court system that included a Justice Court and Police Court. The Justice Court was a “court of limited jurisdiction” under the purview of King County. (In contrast, the city of Seattle was the parent agency for the Police Court.) The justices of the peace on the bench of the Justice Court dealt with misdemeanors, traffic offenses, minor civil suits, and small claims, and also heard liquor-related cases during Prohibition. More serious cases were referred to the county’s Superior Court. In 1961, the Washington State Justice Court Act combined the Justice Court and the District Court into one entity, a change that was adopted by King County in 1962.

Prohibition in Washington State began in 1916, three years before the U.S. Constitution was amended to outlaw the manufacture, transportation, and sale of alcohol on a national level. The state law was less draconian – county auditors were allowed to grant permits to import limited amounts of alcohol – but was still widely violated. Bootleggers and rumrunners did a thriving business supplying Washingtonians with illegal liquor, and many people built stills to manufacture their own. Until Prohibition was repealed in 1933, Seattle civic leaders cracked down on this activity to varying degrees. Mayor Hiram Gill was among the more severe, establishing a widely criticized “Dry Squad” to raid businesses and homes suspected of violating the ban.
