Miss. Code Ann. § 51-31-67: Miss. Code Ann. § 51-31-67

If the court, chancellor, or drainage commissioners have underestimated the amount or the costs of work necessary for any district, then on the recommendation of the commissioners, the court or chancellor may order such additional work done or such additional costs paid and may, with the approval of the commissioners and on their recommendation, reassess the several properties of the district in proportion to the benefits to accrue to such respective properties. In such case the commissioners shall report the facts as they are required to report the benefits and assessments in the first instance, and the court or chancellor shall hear their report and all objections thereto on the same notice to the parties interested as in the first instance of approving assessments and benefits. Appeal shall lie from decree as in the first instance, and they shall be final only as decrees are final in the first instance.
