California Code, Business and Professions Code - BPC § 7036

(a) Notwithstanding any other provision of this chapter, the Attorney General may bring a civil action to impose discipline upon, to deny an application for, or to deny continued maintenance of, a contractor's license.  The civil action shall be brought on the grounds that a person has failed to pay its workers the full amount of wages that the workers are entitled to under state law, has not fulfilled a wage judgment, or is in violation of an injunction or court order regarding the payment of wages to its workers.

(b) The Attorney General shall notify the registrar at least 30 days prior to filing a civil complaint pursuant to subdivision (a).  The Attorney General's failure to provide this notice shall not constitute a defense to the action.

(c) The board may intervene in any court proceedings brought pursuant to this section within 60 days of the filing of the initial complaint.  After that time, intervention shall be by leave of court upon good cause shown.  If the board elects not to intervene, the election shall be deemed consent by the board to comply with any order of the court issued pursuant to subdivision (d) and to be subject to the court's jurisdiction to enforce the order, if necessary.  No action or inaction under this section shall preclude the registrar from independently or concurrently proceeding administratively against the contractor's license and obtaining administrative remedies for any violations not alleged in the Attorney General's complaint, whether or not the board has intervened.

(d) Upon the Attorney General establishing the cause of action described in subdivision (a), the following shall apply:

(e) Nothing in this section shall preclude or require the board to investigate a license for violations of this chapter pursuant to Sections 7011.7 and 7090 or require the board to afford notice or a hearing under the provisions of Chapter 5 (commencing with Section 11500) of Part 1 of Division 3 of Title 2 of the Government Code.

(f) A good faith mistake regarding which wage rate applies to a particular category of work, including, but not limited to, for purposes of payment of prevailing wages, shall not constitute a violation under this section.
