The U.S. and Illinois constitutions guarantee that every person charged with criminal or civil wrongdoing, with few exceptions, has the right to a trial by a jury of one's peers. The jury plays a pivotal role in a case: its members are charged with making a fair and impartial decision based on the facts presented during the trial.

Being a juror presents citizens with the opportunity to take an active role in their government as well as help them experience firsthand how our court system works. It is an important responsibility and an extremely satisfying one for most people.

To be eligible for jury duty, you must be a citizen of the United States, at least 18 years old, a resident of the county that issued the summons, and have the ability to read, write and understand the English language. There are no education or skill requirements, and you do not need to know about the law. Those summoned for jury duty are either registered voters, have a driver's license, an Illinois Identification Card or an Illinois Disabled Person Identification Card.

Some exemptions for hardship are available. In addition, convicted felons may be exempt, depending upon the nature of the felony and how long ago it occurred.

Jury summons are sent through the mail to a citizen's home. If you receive a summons, you must report to the address indicated on the summons at the time stated. Failure to do so may result in your being held in contempt of court, and you may be fined or in extreme circumstances, receive a jail sentence.

If you cannot appear on the summons date, you can ask for a postponement by calling the phone number on the summons to explain why you cannot appear.

Once at court, prospective jurors are grouped into panels from which trial juries are selected.
