In the enforcement of the provisions of this article, the attorney general may accept an assurance of discontinuance of any act or practice deemed in violation of the provisions of this article from any person engaging in, or who has engaged in, such act or practice. Such assurance may include a stipulation for the payment by such person of reasonable expenses incurred by the attorney general or as restitution to aggrieved persons, or both. Any such assurance shall be in writing and shall be filed with and subject to the approval of the superior court of the county in which the alleged violator resides or has its principal place of business or in Maricopa county. A violation of such assurance within six years of the filing thereof shall constitute prima facie proof of a violation of the provisions of this article. Such assurance of discontinuance shall not be considered an admission of a violation for any purpose.
