Classification 23: Prohibition

This classification was established formally in 1924 for violations of the 18th Amendment (Prohibition) and its implementing legislation. Although not the agency of primary jurisdiction, the FBI conducted investigations at the request of the Justice Department until 1928 when it gained authority to start investigations on its own. With the repeal of Prohibition in 1933, any further investigative duties were transferred to the Treasury Department, but the FBI continued to investigate liquor shipments from wet to dry states until 1936, when this responsibility also was shifted to Treasury.
