Illinois Statutes Chapter 705. Courts § 5/11. Marshals

(a) The office of marshal for the Supreme Court is hereby created, such marshals to be selected by the Supreme Court, and the duties of such marshals shall be to attend upon its sittings and to perform such other duties, under the order and direction of the said court, as are usually performed by sheriffs of courts. The salary of such marshals shall be fixed by the judges of the Supreme Court, such salary to be payable from the State treasury, upon bills of particulars, signed by any one of the judges of the Supreme Court.

(b) Marshals are peace officers and have all the powers possessed by police officers in cities and by sheriffs. Marshals may exercise these powers throughout the State. No marshal has peace officer status or may exercise police powers unless: (i) he or she successfully completes the basic police training course mandated and approved by the Illinois Law Enforcement Training Standards Board; or (ii) the Illinois Law Enforcement Training Standards Board waives the training requirement by reason of the marshal's prior law enforcement experience or training or both.

(c) The office of marshal for the Supreme Court may also employ court security officers to be responsible for maintaining the security of any courthouse or courtroom occupied by the Supreme or Appellate Court of this State. A court security officer has the authority to arrest in the same manner as authorized by similarly certified officers of a county sheriff. However, the arrest powers of the court security officer are limited to the performance of the official duties of the court security officer. A court security officer who is trained and qualified as permitted by law may carry a weapon at his or her place of employment and to and from his or her place of employment. No court security officer authorized under this Section may exercise arrest powers or carry a firearm unless: (i) he or she successfully completes the basic court security officer training course mandated and approved by the Illinois Law Enforcement Training Standards Board; or (ii) the Illinois Law Enforcement Training Standards Board waives the training requirement by reason of the individual's prior experience or training or both.
