Section 48-592 - Invalidity of liens or bonds; extent of validity; means to secure interest of persons damagedA. If the lien of an assessment or reassessment, or of a bond issued to represent the amount assessed on any lot is held invalid by a court because a portion of the improvement ordered was without the power of the governing body to order, or was not properly embraced within the contract for the work, or in the assessment made to cover the expenses, the owner of the warrant or the holder of the bond is entitled to a judgment determining what portion of the assessment was legal. There shall thereafter be issued to him by the superintendent within sixty days, and in accordance with the directions of the judgment, a new assessment for an amount which the court finds was the reasonable value of the portion of the improvement legally authorized by the proceedings, which amount shall be reassessed upon the property in the same manner and with like effect as provided for issuing the original assessment, and may be enforced as an original assessment. The holder of bonds representing the original assessment shall be entitled to new bonds on each lot representing the amount of the reassessment.B. If the lien of an assessment, or of a bond issued therefor, is held invalid by a court for any cause arising subsequent to the time the authority of the governing body attaches to order the work, or when the lien is defeated or held invalid for any cause, and it also appears that the owner of the property, holding it at the time the notice of the award of contract was published, had personal knowledge of the intention to order award of the contract, and has not filed a protest against the improvement or a notice of his objection to the award of contract, the owner of the assessment or bond may recover from the owner of the lot covered by the assessment such sum as the court shall find the lot to have been actually benefited by the improvement, not exceeding the amount which would have been properly assessable against the lot.
