U.S. Circuit Court, District of Illinois
Congress established the U.S. Circuit Court, District of Illinois on March 3, 1819. The law creating the court established Illinois as a district, with a district judge who was to hold sessions twice a year, in May and December, in the state capital. As initially created, the court was not in an existing judicial circuit, so appeals from the court went directly to the United States Supreme Court. In 1837, Congress establish the circuit court of appeals system, placing the District of Illinois within the Seventh Circuit. In 1851, Congress changed the court's biannual sessions to the first Monday in July and the third Monday in December, and added additional terms on the first Tuesday of October and the third Tuesday of April each year. Congress eliminated the District in 1855, when the state was divided into northern and southern districts.
