California Code, Education Code - EDC § 88129

No warrant shall be drawn by or on behalf of the governing board of any district for the payment of any salary or wage to any employee in the classified service unless the assignment bears the certification of the personnel director that the person named in the assignment has been employed and assigned pursuant to this article and the rules of the commission.

Whenever the commission, after a public hearing, finds that any appointment has been made in violation of this article or the rules of the commission as they apply to examination procedures, the commission may order that no salary warrant shall thereafter be drawn to the employee so appointed, for services rendered after the date of said order. Any violation of this article or the rules of the commission as they apply to examination procedures shall constitute grounds for the dismissal of the employee or employees guilty of such violation.
