(d)Subpoena and contempt power. - The Board shall have power to issue subpoenas through the Clerk of the Supreme Court of Appeals. The Clerk shall prepare and have available for issuance at the request of any party, subpoenas returnable before the Board for attendance of witnesses or for the production of documentary evidence. Subpoenas, and other process of the Board, may be served in the same manner provided for service of subpoenas to the circuit courts of this State and may be served by mail or by any person designated by the Board or Clerk. The Board shall have jurisdiction co-extensive with the circuit courts of this State to compel the attendance of witnesses and the production of documents; and the failure of any person without adequate excuse to obey a subpoena or other process of the Board shall constitute contempt of the Board. All witnesses shall be entitled to such witness fees and expenses as in any civil proceeding in this State. The Board or its appointed hearing officer may punish breaches of order and unprofessional conduct committed in its presence on the part of counsel, or any other person, by censure or exclusion from any hearing or may invoke the aid of any circuit court in keeping order. Such court, in case of the refusal of any person to maintain order before the Board or hearing officer, shall issue an order requiring such person to maintain order. Any failure to obey such order of the court may be punished by such court as contempt thereof. The Board or hearing officer may designate a person, or persons to act as bailiff or bailiffs to be in attendance at all its hearings.
