No order may be entered under Section 25212, 25213, 25213.3, or 25252 except after notice to any person affected thereby (and, in the case of an agent, to his or her employer or prospective employer if known to the commissioner) of the intention of the commissioner to enter that order and of the reasons therefor and that upon receipt of a request the matter will be set down for hearing to commence within 15 business days after that receipt unless the person affected consents to a later date. If no hearing is requested within 30 days after the mailing of the notice and none is ordered by the commissioner, the order may be entered without hearing to remain in effect until it is modified or vacated by the commissioner. In the case of an original application for a certificate, that hearing shall be set down to commence within 15 business days after receipt of a written request by the applicant made 30 days or more after the filing of the application, even though no notice by the commissioner has been given, unless the applicant consents to a later date. If a hearing is requested or ordered, it shall be held in accordance with the provisions of the Administrative Procedure Act (Chapter 5 (commencing with Section 11500) of Part 1 of Division 3 of Title 2 of the Government Code), and the commissioner shall have all of the powers granted thereunder.
