All subpoenas 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 fees of witnesses before the circuit courts 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 Illinois Housing Development Authority or a member, officer or employee thereof, and the disbursements made in the payment of such fees shall be audited and paid in the same manner as are other expenses of the Illinois Housing Development Authority. Whenever a subpoena is issued at the instance of a party to any proceeding before the Illinois Housing Development Authority, the Illinois Housing Development Authority may require that the cost of service thereof and the fee of witnesses shall be borne by the party at whose instance the witness is summoned and the Illinois Housing Development Authority shall have power at its discretion to require a deposit to cover the cost of such service and witness fee and the payment of the legal witness fee and mileage to the witness when served with subpoena. A subpoena issued so shall be served in the same manner as a subpoena issued out of a court.
Any person who shall be served with a subpoena to appear and testify or to produce books, papers, accounts or documents issued by the Illinois Housing Development Authority or any member or officer thereof in the course of an inquiry, investigation or hearing conducted under any of the provisions of this Act and who shall refuse or neglect to appear or to testify or to produce books, papers, accounts and documents relevant to the inquiry, investigation or hearing as commanded in such subpoena, shall be guilty of a Class A misdemeanor.
Any Circuit Court of this State, upon application of the Illinois Housing Development Authority or a member, officer or employee thereof, may, in his discretion, compel the attendance of witnesses, the production of books, papers, accounts and documents and the giving of testimony before the Illinois Housing Development Authority, or a member, officer or employee thereof, by an attachment for contempt or otherwise, in the same manner as production of evidence may be compelled before such court.
