Neb. Rev. Stat. § 77-1620: Judgments against public corporations; payment by levy in addition to levy for ordinary purposes.

If the amount of revenue derived from taxes levied and collected for ordinary purposes shall be insufficient to meet and pay the current expenses for the year in which the levy is made, and also to pay the judgments remaining unpaid, it shall be the duty of the proper officers of the corporation, against which any such judgments shall have been obtained and remain unsatisfied, to at once proceed and levy and collect a sufficient amount of money to pay off and discharge such judgments.
