Validation of irregular proceedings.

A. No fault in any notice or other proceeding shall affect the validity of any proceeding under this act, except to the extent to which it can be shown that such fault resulted in a material denial of justice to the property owner complaining of such fault. B. In case it be found upon a hearing, that by reason of some irregularity or defect in the proceedings, the appraisal has not been properly made, the court may, nevertheless, on having proof that expense has been incurred which is a proper charge against the property of the complainant, make an order finding the amount of benefits to said property, and appraising the proper benefits accordingly, subject to a claim for a jury as provided, and thereupon said land shall be assessed as other land equally benefited. C. In the event that, either before or after the issuance of bonds, the appraisal of benefits, either as a whole or in part, be declared by any court of competent jurisdiction, to be invalid by reason of any defect or irregularity in the proceedings therefor, whether jurisdictional or otherwise; the court where the original case is pending is hereby authorized and directed; on the application of the board, or of any holder of any bonds which may have been issued, promptly and without delay, to remedy all defects or irregularities as the case may require, by directing and causing to be made in the manner hereinbefore provided, a new appraisal of the amount of benefits against the whole or any part of the property in the said district as the case may require.
