If after hearing all contests and considering the report of the board of appraisers, the court shall find that the estimated costs of works and improvements as reported by the appraisers, or as amended by the court, exceed the estimated benefits, the court shall decree the board of commissioners unauthorized to put into effect the plan for reclamation of the district or sub-district, as the case may be, and the clerk of the court shall certify a copy of the decree to the secretary of the board of commissioners who shall enter the decree in the records of the drainage district.  

In case a plan for reclamation is rejected by the court as above provided, the board of commissioners, when petitioned to that effect by the landowners owning a majority of the land in the drainage or sub-drainage district, as the case may be, may cause other and amended plans for reclamation to be prepared by the engineer.  The procedure in the case of the new or amended plan for reclamation shall be the procedure provided in the case of the original plan for reclamation; and the funds with which to pay the preliminary expenses of the new or amended plan for reclamation, the making of additional surveys, new assessments, and other necessary expenses, shall be advanced by the petitioning landowners, and reimbursed to them by the board of commissioners when the funds therefor shall be available.
