Each attorney-at-law admitted to practice within the state, while in good standing, shall be a commissioner of the Superior Court and, in such capacity, may, within the state, sign writs and subpoenas, take recognizances, administer oaths and take depositions and acknowledgments of deeds. Each such attorney may also issue subpoenas to compel the attendance of witnesses and subpoenas duces tecum in administrative proceedings. If, in any administrative proceeding, any person disobeys such subpoena or, having appeared in obedience thereto, refuses to answer any proper and pertinent question or refuses to produce any books, papers or documents pursuant thereto, application may be made to the Superior Court or any judge thereof for an order compelling obedience.
