# Illinois circuit courts

The Illinois circuit courts are state courts of the judiciary of Illinois. They are trial courts of original and general jurisdiction. As of 2024, outside of Cook County which has its own circuit court, there are 24 numbered circuits, which may include one or more counties of Illinois—the numbering of the circuits is based on when they were created, generally new higher numbers go to circuits that were later created from out of the lower numbered circuit courts.

## Judges

There are two kinds of judges in the circuit court: circuit judges and associate judges. Circuit judges are elected for six years, may be retained by voters for additional six-year terms, and can hear any kind of case. Circuit judges are elected on a circuit-wide, or "at-large", basis or from the county or sub-circuit where they reside, depending on how the particular seat was created. The Illinois State Constitution provides that each county have at least one circuit judge elected from that county's residents. Additional "resident" circuit judges may exist pursuant to a constitutional provision or legislative act. Associate judges are appointed by the circuit judges of a circuit pursuant to Supreme Court rule to serve four-year terms. Associate judges may be reappointed by the circuit judges for additional four-year terms. The terms of all associate judges throughout the state run concurrently; i.e., they all expire on the same date regardless of when an associate judge is appointed. An associate judge can hear any case, except criminal cases punishable by a prison term of one year or more, unless the associate judge has received approval from the Chief Judge of the respective circuit court to hear other criminal cases. Circuit judges in a circuit elect one of their members to serve as chief judge of the circuit court. Judges of the court may be assigned to general or specialized divisions by the chief judge, who has general administrative authority in the circuit, subject to the overall administrative authority of the Supreme Court.

## Jurisdiction

The circuit court has general jurisdiction and can decide, with few exceptions, any kind of case. The exceptions are redistricting of the Illinois General Assembly and the ability of the governor of Illinois to serve or resume office. The circuit court also shares jurisdiction with the Supreme Court of Illinois to hear cases relating to revenue, mandamus, prohibition, and habeas corpus. However, if the Supreme Court chooses to exercise its jurisdiction over these cases, the circuit court may not decide them. The circuit court also reviews administrative decisions of certain state agencies. Circuit courts may also have concurrent jurisdiction with federal courts, subject to removal jurisdiction.

## Circuits

There are 25 judicial circuits in the state, each comprising one or more of Illinois' 102 counties. The jurisdiction of seven of these circuits courts are solely within the confines of a single county; these are Cook, Kane, Will, DuPage, Lake, McHenry (all Chicago metropolitan area counties), and St. Clair in Metro East. The other 18 circuits each contain between two and 12 counties.
