(a) The board may not recommend suspension or revocation of licensure or refuse to issue or to renew any license for any cause listed in Section 34-26-46 unless the person accused has been given at least 30 days' notice in writing of the charge against him or her and a public hearing by the board. The written notice shall be mailed to the person's last known address, but the nonappearance of the person shall not prevent such a hearing. Upon such a hearing the board may administer oath and procure by its subpoenas the attendance of witness and the production of relevant books and papers.
(b) At least one member of the board shall be present at all times during a hearing, deliberation, and action thereon. A board member who has assisted with an investigation of a complaint may not vote on the disciplinary action to be taken relating to the complaint. A hearing officer appointed by the Attorney General shall act as the hearing officer for the purpose of ruling on motions, evidence, and other like matters.
