N.D. Cent. Code § 11-09-48
At any time after any form of county managership has been in force in a county for a period of four years, the board of county commissioners may submit, and, when petitioned to do so at least ninety days before a primary election by at least twenty-five percent of the qualified electors of the county as determined by the total number of votes cast for the office of governor at the last general election, shall submit to the electors at a primary election the question of whether or not the county manager plan in force shall be retained. If a majority of the legal votes cast on such question at the primary election shall be against retaining such plan, it shall cease to be operative on the first Monday in January next succeeding the primary election, and the county shall revert to the plan of government in force prior to the adoption of the county managership. Thereafter, the provisions of this chapter shall not be applicable in such county until after another compliance with its terms. When the petition has been filed, candidates for all county offices required under the plan in force prior to the adoption of the county managership may file nominating petitions. If a majority of the legal votes cast on the question are against retaining the county manager plan, the candidates nominated at the primary election shall be voted upon at the general election, and officers shall be elected in accordance with the general election laws. The terms of office of all officers elected as provided in this section shall commence on the first Monday in January next succeeding the primary election.
