Secretary's investigatory and subpoena powers.

(b) The secretary may, in connection with the performance of his duties under any other statute or act, apply to the superior court for the judicial district of Hartford, or to a judge of the court if the court is not in session, for a subpoena to compel the attendance and testimony under oath of witnesses or the production of books, records, vouchers, memoranda, documents, letters, tapes or other recordings or other papers or items. The court or judge shall, before issuing the subpoena, provide adequate opportunity for the secretary and the party against whom the subpoena is requested to be heard. No such subpoena shall be issued unless the court or judge finds that the attendance and testimony of the witness or the production of the requested material is reasonably necessary to carry out the purposes of such other statute or act and that the secretary has made reasonable efforts to secure the attendance, testimony and requested material without recourse to compulsory process. Such subpoena shall be served by a proper officer or indifferent person.
