(20 ILCS 415/12a) (from Ch. 127, par. 63b112a)
    Sec. 12a. Certification of payrolls.
    (1) No state disbursing or auditing officer shall make or approve or take any part in making or approving any payment for personal service to any person holding a position in the State service subject to this Act with the exception of those exempt under Section 4c unless the payroll voucher or account of such pay bears the certification of the agency head, or of his authorized agent, that there has not been a determination made by the agency that any person named in the payroll voucher or account of such pay was not appointed and employed in accordance with the provisions of this law and rules, regulations, and orders thereunder.
    Auditing by the Department shall be based either upon verification of the individual items in each payroll period or upon procedures developed for avoiding unnecessary repetitive verification when other evidence of compliance with applicable laws and rules is available. Such procedures may be based either upon a continuation of payroll preparation by individual agencies or upon the use of a central payroll preparation unit. The Director may for proper cause withhold certification or approval from an entire payroll or from any specific item or items thereon.
    (2) On and after July 1, 1957, any citizen may maintain a suit to restrain a disbursing officer from making any payment in contravention of any provisions of this law, rule, or order thereunder. Any sum paid contrary to any provision of this law or of any rule, regulation, or order thereunder may be recovered in an action maintained by any citizen, from any officer who made, approved, or authorized such payment or who signed a voucher, payroll, check or warrant for such payment, or from the sureties on the official bond of any such officer. All moneys recovered in any such action shall be paid into the State treasury.
