The Illinois Trial Management Call Order (IT MCO) is an electronic system used by the Circuit Court of Cook County to manage jury trials. The IT MCO system is designed to streamline the process of scheduling trials, including setting trial dates, assigning judges, and appointing jurors. The IT MCO is used to manage criminal, civil, and domestic relations cases. There are three types of Illinois Trial Management Call Order: 1. Pre-trial Management Call Order: This call order is used to set trial dates and assign judges to the cases. 2. Jury Management Call Order: This call order is used to manage the pool of prospective jurors for criminal and civil cases. It allows the court to select a jury panel for the scheduled trials and to assign jurors to those trials. 3. Post-trial Management Call Order: This call order is used to manage the payment of jurors and the disposition of cases after the trial is completed. It allows the court to track the payment of jury fees and to close out cases.
