No person connected with any complaint, investigation, or other proceeding before the board, including, but not limited to, any witness, counsel, counsel's secretary, board member, board employee, court reporter, or investigator, may mention the existence of the complaint, investigation, or other proceeding, disclose any information pertaining to the complaint, investigation, or other proceeding, or discuss any testimony or other evidence in the complaint, investigation, or other proceeding, except to persons involved and having a direct interest in the complaint, investigation, or other proceeding, and then only to the extent necessary for the proper disposition of the complaint, investigation, or other proceeding. However, whenever the board receives information in any complaint, investigation, or other proceeding before it indicating a violation of state or federal law, the board may provide that information, to the extent the board considers necessary, to the appropriate state or federal law enforcement agency or regulatory body. Nothing contained in this section may be construed so as to prevent the board from making public a copy of its final order in any proceeding as authorized or required by law.
