Any qualified officer or employee of the Illinois Department, a County Board, or member of the staff of a Commissioner of Appeals, as the case may be, designated in writing to so act by the Director of the Department, Chairman or President of the County Board, or Commissioner of Appeals, may conduct hearings on appeals and may compel, by subpoena, the attendance and testimony of witnesses and the production of books and papers, and administer oaths to witnesses. Wherever feasible, the Public Aid Committee shall itself conduct hearings on appeals by applicants for or recipients of aid under Article VI. No person shall be compelled to attend a hearing at a place outside the county in which he resides. Subpoenas may be served as provided for in civil actions. The fees of witnesses for attendance and travel shall be the same as the fees of witnesses before the circuit court and shall be paid as an expense of administration of the County Department or the local governmental unit, as the case may be.
     If a witness refuses to attend or testify, or to produce books or papers, concerning any matter upon which he might be lawfully examined, the circuit court of the county wherein the hearing is held, upon application of the Illinois Department, Public Aid Committee, or Commissioner of Appeals, as the case may be, may compel obedience by proceedings as for contempt as in case of a like refusal to obey a similar order of the court.
