Trial by jury is a fundamental part of the American system of justice, and is a right guaranteed under the Constitution of the United States and the Constitution of the State of Illinois. To preserve this right it is essential that the court establish and maintain a well-functioning system for the selection and utilization of jurors.

Winnebago County utilizes the ONE DAY/ONE TRIAL system of jury service. Under this system a person called to jury duty serves for the duration of one trial if selected to hear a case. But if the person has not been sent to a courtroom to hear a case by the end of one day, he or she may be discharged from jury duty.

In the current one-day/one-trial jury system, the juror serves for one day only, unless chosen to hear a case lasting more than one day.  The number of names summoned for jury service is based upon the court calendar.  These names are drawn randomly by computer from the master list which is created by a combined list of drivers/voters/identification card and Illinois disabled person ID cardholders in Winnebago County.

The citizens of Winnebago County can take pride in having one of the most modern jury systems operating in Illinois.  When you have completed your service as a juror, it is hoped you will have a higher opinion of the privilege enjoyed by the free citizens of our country to participate in the administration of justice. In serving as a juror, you know that you have discharged a serious responsibility in a conscientious manner.


"Citizens of the United States have enjoyed for over 200 years the right to have their cases decided by a jury of their peers. Jury service is not merely your responsibility - it is also a cherished right."
