(1) The commission is hereby authorized and directed to take legal action against any violator of this chapter. Upon complaint initiated by the commission or filed with it, the licensee or any other person charged with a violation of this chapter shall be given fifteen (15) days' notice of the hearing upon the charges filed, together with notice of the option of appearing before the commission or an administrative hearing officer as provided in subsection (7) of this section, and a copy of the complaint. The applicant or licensee or other violator shall have an opportunity to be heard in person or by counsel, to offer testimony, and to examine witnesses appearing in connection with the complaint. Hearings shall be held at the offices of the Mississippi Real Estate Commission, or at the commission's sole discretion, at a place determined by the commission. At such hearings, all witnesses shall be properly sworn and stenographic notes of the proceedings shall be taken and filed as a part of the record in the case. Any party to the proceedings shall be furnished with a copy of such stenographic notes upon payment to the commission of such fees as it shall prescribe, not exceeding, however, the actual cost to the commission. The preponderance of evidence standard of proof shall be used to examine factors during all hearings. The commission shall render a decision on any complaint and shall immediately notify the parties to the proceedings in writing of its ruling, order or decision.
