(35 ILCS 615/10) (from Ch. 120, par. 467.25)
    Sec. 10. The Department or any officer or employee of the Department designated, in writing, by the Director thereof, shall at its or his or her own instance, or on the written request of any party to the proceeding, issue subpoenas requiring the attendance of and the giving of testimony by witnesses, and subpoenas duces tecum requiring the production of books, papers, records or memoranda. All subpoenas issued under 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 Department or any officer or employee thereof, 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 taxpayer to any such proceeding the Department may require that the cost of service of the subpoena and the fee of the witness be borne by the taxpayer 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 issued as aforesaid shall be served in the same manner as a subpoena issued out of a court.
    Any circuit court of this State, upon the application of the Department or any officer or employee thereof may, in its discretion, compel the attendance of witnesses, the production of books, papers, records or memoranda and the giving of testimony before the Department or any officer or employee thereof conducting an investigation or holding a hearing authorized by this Act, by an attachment for contempt, or otherwise, in the same manner as production of evidence may be compelled before the court.
    The Department or any officer or employee thereof, or any party in an investigation or hearing before the Department, may cause the depositions of witnesses residing within or without 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.
    Notwithstanding any other provision of law, the provisions of the Illinois Independent Tax Tribunal Act of 2012, and the rules adopted pursuant thereto, shall apply to and govern judicial review of final administrative decisions that are subject to the Illinois Independent Tax Tribunal Act of 2012.
