Section 210 ILCS 60/11 - Investigations - Notice - Hearings - Proceedings(a) The Department may, upon its own motion, and shall, upon the verified complaint in writing of any persons setting forth facts which if proven would constitute grounds for the denial of an application for a license or refusal to renew a license or revocation of a license, investigate the applicant or licensee. Before denying an application or refusing to renew a license or revoking a license, the Department shall notify the applicant or licensee.(b) Such notice shall be effected by registered mail or by personal service setting forth the particular reasons for the proposed action and fixing a date, not less than 15 days from the date of such mailing or service, at which time the applicant or licensee shall be given an opportunity for a hearing. Such hearing shall be conducted by the Director or by an employee of the Department designated by the Director as a hearing officer to conduct the hearing. On the basis of any such hearing, or upon default of the applicant or licensee, the Director shall make a determination specifying his findings and conclusions.(c) The procedure governing hearings authorized by this Section shall be in accordance with the Illinois Administrative Procedure Act which is expressly adopted and incorporated herein as if all of the provisions of such Act were included in this Act, except that in case of conflict between the two Acts the provisions of this Act shall control.(d) The Director or hearing officer shall, upon his own motion, or on the written request of any party to the proceeding, issue subpoenas requiring the attendance and the giving of testimony by witnesses, and subpoenas duces tecum requiring the production of books, papers, records or memoranda. All subpoenas and subpoenas duces tecum issued under the terms of this Act may be served by any person of full age. The fees of witnesses for attendance and travel shall be the same as the fees of witnesses before the circuit court of this State, such fees to be paid when the witness is excused from further attendance. When the witness is subpoenaed at the instance of the Director, or hearing officer, such fees shall be paid in the same manner as other expenses of the Department, and when the witness is subpoenaed at the instance of any other party to any such proceeding the Department may require that the cost of service of the subpoena or subpoena duces tecum and the fee of the witness be borne by the party at whose instance the witness is summoned. In such case, the Department, in its discretion, may require a deposit to cover the cost of such service and witness fees. A subpoena or subpoena duces tecum issued as aforesaid shall be served in the same manner as a subpoena issued out of a court.(e) Any circuit court of this State upon the application of the Director, or upon the application of any other party to the proceeding, may, in its discretion, compel the attendance of witnesses, the production of books, papers, records or memoranda and the giving of testimony before the Director or hearing officer conducting an investigation or holding a hearing authorized by this Act, by attachment for contempt, or otherwise, in the same manner as production of evidence may be compelled before the court.(f) The Director or hearing officer, or any party in any investigation or hearing before the Department, may cause the depositions of witnesses within the State to be taken in the manner prescribed by law for like depositions in civil actions in courts of this State, and to that end compel the attendance of witnesses and the production of books, papers, records or memoranda.
