The board, or its duly authorized agent or agencies, shall have access to, at all reasonable times, for the purpose of examination, and the right to copy any evidence of any person being investigated or proceeded against that relates to any matter under investigation or in question. The board or any member of the board on application of any party to such proceedings forthwith shall issue to such party subpoenas requiring the attendance and testimony of witnesses or the production of any evidence in such proceeding or investigation requested in such application. Within five days after the service of a subpoena on any person requiring the production of any evidence in his possession or under his control, such person may petition the board to revoke, and the board shall revoke, the subpoena if in its opinion the evidence whose production is required does not relate to any matter under investigation, or any matter in question in such proceedings, or if in its opinion such subpoena does not describe with sufficient particularity the evidence whose production is required. Any member of the board, or any agent or agency designated by the board for such purposes, may administer oaths and affirmations, examine witnesses and receive evidence. The attendance of witnesses and the production of the evidence may be required from any place in this state at any designated place of hearing.B. In case of contumacy or refusal to obey a subpoena issued to any person, the superior court in the county within the jurisdiction of which the person guilty of contumacy or refusal to obey is found or resides or transacts business, on application by the board, has jurisdiction to issue to such person an order requiring the person to appear before the board, or a member, agent or agency of the board, to produce evidence if so ordered or to give testimony touching the matter under investigation or in question. Failure to obey the order of the court may be punished by the court as contempt.C. Complaints, orders and other process and papers of the board, or a member, agent or agency of the board, may be served either personally, by registered or certified mail, by telegraph or by leaving a copy at the principal office, place of business or residence of the person required to be served. The verified return by the individual personally serving or leaving the copy, setting forth the manner of the service, and the return post office receipt, if registered or certified, or telegraph receipt and mailed or telegraphed as provided in this subsection, are proof of service.
