Bus. & Prof. Code, § 22358

(a) A certificate of registration may be revoked or suspended whenever it has been determined that the registrant has made a service of process, including service completed by an employee or independent contractor of the registrant, which does not comply with the provisions of law governing the service of process in this state or constitutes an improper service of process not amounting to a violation of law.

(b) An investigation concerning the revocation or suspension of a certificate of registration may be commenced at any time at the option of the county clerk if the county clerk deems it to be appropriate. A complaint by any person who has alleged that he or she has been injured by a service of process shall be investigated by the public prosecutor. The investigation shall determine if the registrant complied with the provisions of law governing the service of process or constituted improper service of process not amounting to a violation of the law.

(c) If the public prosecutor determines from the investigation that cause may exist for the suspension or revocation of the certificate of registration, he or she shall set the matter for hearing and give notice to the registrant. That hearing shall be conducted in accordance with Chapter 5 (commencing with Section 11500) of Division 3 of Title 2 of the Government Code except that the decision of the administrative law judge shall be final. For the purposes of those provisions, the public prosecutor shall be deemed to be the agency.

(d) If, after the hearing, the county clerk is notified after the decision has become effective that the administrative law judge has directed that the registrant’s certificate be suspended or revoked, the county clerk shall forthwith suspend or revoke the certificate. If the certificate is revoked, the bond or cash deposit required by Section 22353 shall be forfeited to the county treasury subject to the right of a person to recover against the bond or cash deposit under Section 22357.
