If upon final determination the petitioner has paid more than the amount so determined to be due, judgment shall be entered in favor of the petitioner for such excess, and upon filing a copy thereof with the county auditor the auditor shall forthwith draw a warrant upon the county treasurer for the payment thereof; provided that, with the consent of the petitioner, the county auditor may, in lieu of drawing such warrant, issue to the petitioner a certificate stating the amount of such judgment, which amount may be used to apply upon any taxes due or to become due for the taxing district or districts whose taxes or assessments are reduced, or their successors in the event of a reorganization or reincorporation of any such taxing district. In the event the auditor shall issue a warrant for refund or certificates, the amount thereof shall be charged to the state and other taxing districts in proportion to the amount of their respective taxes included in the levy and deduct the same in the subsequent distribution of any tax proceeds to the state or such taxing districts, and upon receiving any such certificate in payment of other taxes, the amount thereof shall be distributed to the state and other taxing districts in proportion to the amount of their respective taxes included in the levy; provided that if in the judgment the levy of one or more of the districts be found to be illegal, to the extent that the tax so levied is reduced on account of the illegal levies, the amount to be charged back shall be charged to the districts and the amount thereof deducted from any distributions thereafter made to them.
