Illinois Statutes Chapter 820. Employment § 130/10. Witnesses; subpoena

§ 10. The Director of the Department of Labor, or his or her authorized representative may interview workers, administer oaths, take or cause to be taken the depositions of witnesses, and require by subpoena the attendance and testimony of witnesses, and the production of all books, records, and other evidence relative to the matter under investigation or hearing. Such subpoena shall be signed and issued by the Director or his or her authorized representative.

Upon request by the Director of Labor or his or her deputies or agents, records shall be copied and submitted for evidence at no cost to the Department of Labor. Every employer upon request shall furnish to the Director or his or her authorized representative, on demand, a sworn statement of the accuracy of the records. Any employer who refuses to furnish a sworn statement of the records is in violation of this Act.

In case of failure of any person to comply with any subpoena lawfully issued under this Section or on the refusal of any witness to produce evidence or to testify to any matter regarding which he or she may be lawfully interrogated, it is the duty of any circuit court, upon application of the Director or his or her authorized representative, to compel obedience by proceedings for contempt, as in the case of disobedience of the requirements of a subpoena issued by such court or a refusal to testify therein. The Director may certify to official acts.
