The director of the administrative procedures division of the secretary of state‘s office may issue subpoenas on behalf of an administrative judge employed by the secretary of state. The administrative judge or hearing officer shall decide any objection relating to discovery under this chapter or the Tennessee Rules of Civil Procedure. Witnesses under subpoena shall be entitled to the same fees as are now or may hereafter be provided for witnesses in civil actions in the circuit court and, unless otherwise provided by law or by action of the agency, the party requesting the subpoenas shall bear the cost of paying fees to the witnesses subpoenaed.
(b) In case of disobedience to any subpoena issued and served under this section or to any lawful agency requirement for information, or of the refusal of any person to testify in any matter regarding which such person may be interrogated lawfully in a proceeding before an agency, the agency may apply to the circuit or chancery court of the county of such person’s residence, or to any judge or chancellor thereof, for an order to compel compliance with the subpoena or the furnishing of information or the giving of testimony. Forthwith, the court shall cite the respondent to appear and shall hear the matter as expeditiously as possible. If the disobedience or refusal is found to be unlawful, the court shall enter an order requiring compliance.
