The Supreme Court of Illinois is the state supreme court of the state of Illinois. The court's authority is granted in Article VI of the current Illinois Constitution, which provides for seven justices elected from the five appellate judicial districts of the state: Three justices from the First District (Cook County) and one from each of the other four districts. Each justice is elected for a term of ten years and the chief justice is elected by the court from its members for a three-year term.
While the justices of many states' supreme courts are expected to relocate to the state capital for the duration of their terms of office, the justices of the Illinois Supreme Court continue to reside in their home districts and have chambers in their respective appellate districts (for example, the three First District justices are chambered in the Michael Bilandic Building in Chicago). The justices travel to Springfield to hear oral arguments and deliberate. Accordingly, the Illinois Supreme Courthouse includes temporary apartments for the justices' use while in Springfield.
