(IV) The board shall provide notice, in the manner set forth in paragraph (b) of this subsection (6), of the final cease-and-desist order within ten calendar days after the hearing conducted pursuant to this paragraph (c) to each person against whom the final order has been issued.

(7) If it appears to the board, based upon credible evidence presented to the board, that a person has engaged in or is about to engage in any unlicensed or unregistered act or practice, any act or practice constituting a violation of this article, any rule promulgated pursuant to this article, any order issued pursuant to this article, or any act or practice constituting grounds for administrative sanction pursuant to this article, the board may enter into a stipulation with such person.

(8) If any person fails to comply with a final cease-and-desist order or a stipulation, the board may request the attorney general or the district attorney for the judicial district in which the alleged violation exists to bring, and if so requested such attorney shall bring, suit for a temporary restraining order and for injunctive relief to prevent any further or continued violation of the final order.

(9) A person aggrieved by the final cease-and-desist order may seek judicial review of the board's determination or of the board's final order as provided in section 12-58-110.4.
