N.D. Cent. Code § 61-24-03.1
Whenever a vacancy exists on a general election no-party ballot for any directorship of the Garrison Diversion Conservancy District, the vacancy may be filled by filing with the county auditor at least sixty-four days before the day of the election and not later than four p.m. of that day a petition substantially in the form provided in section 61-24-03, stating that the petitioner desires to become a candidate for election to the office of director. This petition must contain the signatures of not less than fifty qualified electors of the county, unless there were at least fifty write-in or sticker votes for the petitioner cast in the no-party primary election for the office.
A vacancy in the no-party ballot is deemed to exist when no candidate is nominated at the primary election or when a candidate nominated at the primary dies, resigns, or otherwise becomes disqualified to have that person's name printed on the ballot at the general election.
