N.D. Cent. Code § 58-18-07
Any aggrieved freeholder may appeal the special assessment against the freeholder's real property by providing the township clerk a written notice of appeal, stating the grounds upon which the appeal is based, within twenty days after the special township meeting. The clerk shall notify the township board of supervisors of the appeal and schedule a special meeting to hear the appeals by publishing a notice of the special meeting at least ten days before the meeting in a legal newspaper published in the township or, if no such newspaper exists, in the county's official newspaper. Any aggrieved freeholder who submitted an appeal may be heard and may present reasons to change the freeholder's assessment at the special meeting. The board of township supervisors may hear the appeals and reasons and may increase or diminish any of the assessments as it may deem just, providing that the total amount of the assessments may not be changed and an assessment as adjusted may not exceed the benefits to the parcel of land on which it is assessed.
