The United States District Court for the District of Kentucky was one of the original 13 courts established by the Judiciary Act of 1789, 1 Stat. 73, on September 24, 1789. At the time, Kentucky was not yet a state, but was within the territory of the state of Virginia. The District was unchanged when Kentucky became a state on June 1, 1792. On February 13, 1801 the Judiciary Act of 1801, 2 Stat. 89, abolished the U.S. district court in Kentucky, but the repeal of this Act restored the District on March 8, 1802, 2 Stat. 132. The District was subdivided into Eastern and Western Districts on February 12, 1901, by 31 Stat. 781.
The United States Attorney's Office for the Western District of Kentucky represents the United States in civil and criminal litigation in the court. The office is currently vacant, as the previous United States Attorney, David J. Hale, was confirmed as a federal judge for the Western District of Kentucky on December 3, 2014.
