735 ILCS 5/11-101
No temporary restraining order shall be granted without notice to the adverse party unless it clearly appears from specific facts shown by affidavit or by the verified complaint that immediate and irreparable injury, loss, or damage will result to the applicant before notice can be served and a hearing had thereon. Every temporary restraining order granted without notice shall be indorsed with the date and hour of signing; shall be filed forthwith in the clerk's office; shall define the injury and state why it is irreparable and why the order was granted without notice; and shall expire by its terms within such time after the signing of the order, not to exceed 10 days, as the court fixes, unless within the time so fixed the order, for good cause shown, is extended for a like period or unless the party against whom the order is directed consents that it may be extended for a longer period. The reasons for the granting of the extension shall be stated in the written order of the court. In case a temporary restraining order is granted without notice, the motion for a preliminary injunction shall be set for hearing at the earliest possible time and takes precedence over all matters except older matters of the same character; and when the motion comes on for hearing the party who obtained the temporary restraining order shall proceed with the application for a preliminary injunction and, if he or she does not do so, the court shall dissolve the temporary restraining order.
On 2 days' notice to the party who obtained the temporary restraining order without notice or on such shorter notice to that party as the court may prescribe, the adverse party may appear and move its dissolution or modification and in that event the court shall proceed to hear and determine such motion as expeditiously as the ends of justice require.
Every order granting an injunction and every restraining order shall set forth the reasons for its entry; shall be specific in terms; shall describe in reasonable detail, and not by reference to the complaint or other document, the act or acts sought to be restrained; and is binding only upon the parties to the action, their officers, agents, employees, and attorneys, and upon those persons in active concert or participation with them who receive actual notice of the order by personal service or otherwise.
