40 ILCS 5/1A-105
The Director may administer oaths and affirmations and summon and compel the attendance before him or her and examine under oath any officer, trustee, agent, actuary, attorney, or employee connected either directly or indirectly with any pension fund, or any other person having information regarding the condition, affairs, management, administration, or methods of conducting a pension fund. The Director may require any person having possession of any record, book, paper, contract, or other document pertaining to a pension fund to surrender it or to otherwise afford the Director access to it and for failure so to do the Director may attach the same.
Should any person fail to obey the summons of the Director or refuse to surrender to him or her or afford him or her access to any such record, book, paper, contract, or other document, the Director may apply to the circuit court of the county in which the principal office of the pension fund involved is located, and the court, if it finds that the Director has not exceeded his or her authority in the matter, may, by order duly entered, require the attendance of witnesses and the production of all relevant documents required by the Director in carrying out his or her responsibilities under this Code. Upon refusal or neglect to obey the order of the court, the court may compel obedience by proceedings for contempt of court.
