Except as otherwise provided in this chapter, no warrant purporting to be drawn upon the funds in the hands of the treasurer of any taxing district may be issued in excess of the amount of cash in the hands of the treasurer exclusive of sinking funds and funds for the payment of interest upon bond issues. No indebtedness may be incurred, and no undertakings or expenditures authorized, in excess of unencumbered uncollected taxes which have been levied during the current year plus the unencumbered uncollected taxes of the four preceding years. Any warrant issued, contract entered into, or purported indebtedness incurred, in contravention of this section is null and void, but this provision is not intended to detract from the provisions of section 21-02-03 with reference to the incontestability of certificates of indebtedness. Any officer willfully executing or participating in the execution of any warrant or contract or attempting to incur any indebtedness of any such taxing district in contravention of this section is guilty of a class A misdemeanor. Any officer executing or participating in the execution of any warrant in contravention of this section is personally liable for the payment thereof to the holder in due course.
