All subpoenas issued under the laws of this State pertaining to or concerning savings banks may be served by any person who is not a minor. The fees of witnesses for attendance and travel shall be the same as fees of witnesses before the circuit courts of this State. Witness fees are to be paid at the time the witness is excused from further attendance, when the witness is subpoenaed at the instance of the Secretary or any officer or any employee designated by him or her for the purpose of conducting any investigation, inquiry, or hearing. The disbursements made in the payment of witness fees shall be audited and paid in the same manner as are other expenses of the Secretary. Whenever a subpoena is issued at the instance of a complainant, respondent, or other party to any proceeding, the Secretary may require that the cost of service thereof and the fee of the same shall be borne by the party at whose instance the witness is summoned, and the Secretary shall have power, in his or her discretion, to require a deposit to cover the cost of such service and witness fees and the payment of legal witness fees and mileage to the witness when served with a subpoena. A subpoena issued under this Section shall be served in the same manner as a subpoena issued out of a court.
Any person served with a subpoena to appear and testify or to produce books, papers, accounts, or documents, either in person or by deposition, in the manner provided in this Section, issued by the Secretary or by any officer or any employee designated by him or her to conduct any such investigation, inquiry, or hearing, in the course of an investigation, inquiry, or hearing conducted under any of the provisions of the laws of this State pertaining to savings banks, and who refuses or neglects to appear or to testify, or to produce books, papers, accounts, and documents relative to such investigation, inquiry, or hearing as commanded in such subpoena, shall be guilty of a petty offense.
Any circuit court of this State, on application of the Secretary or an officer or an employee designated by the Secretary for the purpose of conducting any investigation, inquiry, or hearing, may, in his or her discretion, compel the attendance of witnesses, the production of books, papers, accounts, and documents, and the giving of testimony before the Secretary or before any officer or any employee designated by the Secretary for the purpose of conducting any such investigation, inquiry, or hearing, in person or by deposition, in the manner provided in this Section, by an attachment for contempt or otherwise, in the same manner as production of evidence may be compelled before a court.
The Secretary, any officer or employee designated by the Secretary for the purpose of conducting any investigation, inquiry, or hearing, or any party may, in any investigation, inquiry, or hearing, cause the deposition of witnesses residing within or outside of the State to be taken in the manner prescribed by law for taking like depositions in civil cases in courts of this State and, to that end, may compel the attendance of witnesses and the production of papers, books, accounts, and documents.
