The Illinois court system is composed of three basic levels:
|Illinois Circuit Courts||These are the trial level courts of the Illinois system. There are 23 circuit courts in Illinois, each covering 1 to 12 counties. Circuit courts handle trials and local issues and in some cases may review decisions of administrative agencies.|
|Illinois Appellate Courts||The Appellate Courts are the first level of appeal in the Illinois system. There are 5 appellate districts in Illinois, and these courts hear appeals from the Circuit Courts. These courts may also review decisions from administrative agencies.|
|Illinois Supreme Court||The Supreme Court is at the top of the Illinois court food chain and is the last court of appeal in the Illinois system. The Supreme Court hears certain appeals from the Circuit Courts and the Appellate Courts, as well as reviews of death sentences.|
There are also other parts of the Illinois system that deal with special issues, such as arbitration panels in certain counties that review lawsuits under a certain dollar amount. The Illinois Courts website has a good explanation of how a case moves through the Illinois court system.
