Gov. Code, § 18710

All orders and decisions of the board made pursuant to Article VII of the California Constitution or this part shall be obeyed by and are binding upon all parties to a proceeding before it, including, but not limited to, appointing powers and all their employees, including their personnel officers, regardless of whether an appointing power or other party agrees or disagrees with a decision or order of the board.

All orders and decisions, other than orders or decisions of the board itself, shall be reviewed by the executive officer or an employee of the board designated by the executive officer.

If any appointing power or other party refuses or neglects to comply with any such order or decision, the board may , in its sole discretion, after investigation with or without a hearing, do any of the following:

(a) Issue further findings interpreting or clarifying the order or decision.

(b) Issue further findings as to whether an appointing power or other party has or has not complied with the order or decision.

(c) Issue an order to show cause, directed to the appointing power, why the board should not file a petition for a writ of mandate to compel the appointing power to comply with the order or decision.

If the board finds that no good cause exists for the refusal or neglect of the appointing power or other party to comply with the order or decision, the board may issue a further order or decision consistent with its findings. Alternatively, the board may file a petition for a writ of mandate in the manner and in the court provided for by law to compel the appointing power or other party to comply with the order or decision.

This procedure for the enforcement of the orders and decisions of the board is in addition to any other means or procedure which may be provided by law. Nothing in this section shall preclude a party to a proceeding before the board from seeking judicial enforcement of an order or decision of the board.
