Illinois Supreme Court

Illinois Supreme Court is the highest judicial body in the U.S. state of Illinois. Established by the first Constitution of Illinois in 1818, the court holds ultimate appellate jurisdiction over all lower courts in the state and exercises general administrative authority over the Illinois court system. The court's decisions are binding on all other Illinois state courts and it plays a critical role in interpreting Illinois law and the state constitution.

History

The court was first established in Kaskaskia, the state's first capital, following the admission of Illinois to the United States in 1818. Its early history was marked by a circuit-riding system, with justices traveling across the state to hear cases. A significant reorganization occurred under the 1870 Constitution, which created the Illinois Appellate Court to relieve the supreme court's caseload. The modern court's structure was largely defined by the current 1970 Constitution, which centralized the administration of the state's judiciary. Throughout its history, the court has been involved in pivotal moments, including litigation surrounding the Great Chicago Fire of 1871 and the political turmoil of the governorship of Rod Blagojevich.

Composition and selection

The court is composed of seven justices, one of whom is designated as the Chief Justice. Justices are elected from five judicial districts, with three selected from the First District (Chicago) and one from each of the other four districts to ensure geographic representation. Selection occurs through partisan elections for ten-year terms, after which justices may seek retention via a non-competitive yes-or-no vote. Vacancies occurring mid-term are filled by appointment by the court's members, with the appointed justice later standing for election. The current chief justice is Mary Jane Theis, who succeeded Anne M. Burke.

Jurisdiction and powers

The court possesses mandatory jurisdiction in cases involving capital punishment and appeals from decisions declaring a state statute unconstitutional. It exercises discretionary jurisdiction over other cases from the Illinois Appellate Court through the granting of a Petition for leave to appeal. Beyond its appellate role, the court holds inherent supervisory and administrative authority over all lower courts, including the circuit courts. This includes the power to make rules for the state judiciary, assign judges, and oversee the Attorney Registration and Disciplinary Commission. The court also has original jurisdiction in cases relating to revenue, mandamus, prohibition, and habeas corpus.

Notable cases

The court has issued landmark rulings on a wide array of issues. In People v. Bruner (1931), it established the "one-act, one-crime" doctrine. The decision in Tunkl v. Regents of the University of California (1963), while citing California law, influenced Illinois' approach to exculpatory clauses. In People ex rel. Wallace v. Labrenz (1952), the court upheld state intervention to provide a life-saving blood transfusion for a child over religious objections. More recently, in Jorgensen v. Blagojevich (2004), it ruled on the governor's amendatory veto powers. The court also played a central role in the ComEd investigation and subsequent litigation.

Courthouse and facilities

The court's primary seat is the Illinois Supreme Court Building in Springfield, Illinois, located across from the Illinois State Capitol. This historic Beaux-Arts building, completed in 1908, houses the court's main courtroom, chambers, and administrative offices. The court also maintains a large branch facility in the Richard J. Daley Center in Chicago, where it hears arguments several times a year. The Illinois Supreme Court Library, a comprehensive legal research library, serves the justices, state attorneys, and the public from its locations in both Springfield and Chicago.
