In case the court decides that such lands could not, at the time said assessment or assessments were made, be assessed for drainage purposes, and that said assessment or assessments, are void, the commissioner shall levy an additional assessment on all of the assessable lands and corporations in said district based on the last assessment of benefits approved by the court, to pay the sum lost to the district by reason of the void assessment, or shall pay said sum out of the general funds of the district.
