The hearings herein provided may be conducted by the commission itself at a regular or special meeting of the commission, or the commission may designate a hearing officer, who may be the executive director, who shall have the power and authority to conduct such hearings in the name of the commission at any time and place as conditions and circumstances may warrant. The hearing officer shall have the record prepared of any hearing which he has conducted for the commission. Such record shall be submitted to the commission along with that hearing officer’s findings of fact and recommended decision. Upon receipt and review of the record of the hearing and the hearing officer’s findings of fact and recommended decision, the commission shall thereupon render its final decision in the matter. Any person ordered to appear for an alleged violation shall have the right to request a hearing before a majority of the commission if he prefers and such a hearing may then be set for the next regular meeting of the full commission, or specially. A verbatim record of the proceedings of such hearings shall be taken and filed with the commission, together with findings of fact and conclusions of law made by the commission. Witnesses who are subpoenaed shall receive the same fees and mileage as in civil actions. In case of contumacy or refusal to obey a notice of hearing or subpoena issued under this section, the circuit court shall have jurisdiction, upon application of the commission or its representative, to issue an order requiring such person to appear and testify or produce evidence as the case may require and any failure to obey such order of the court may be punished by such court as contempt thereof. Failure to appear at any such hearing, without prior authorization to do so from the commission or its designee, may result in the commission finding the alleged violator guilty of the charges complained of by default, and at such time an order may be entered, including the assessment of a penalty, which, in the opinion of the commission, will best further the purposes of Section 17-17-1 et seq., and Section 49-17-1 et seq.
