N.D. Cent. Code § 16.1-13-34
An individual who votes after the regular poll closing time in an election in which a federal office appears as a result of a federal or state court order or any other order extending the time established for closing the polls under state law in effect ten days before the date of that election may only vote in that election by casting a provisional ballot. The ballot must be marked as a provisional ballot and must be separated and held apart from other ballots cast by those not affected by the order. The secretary of state shall approve the form of any provisional ballot and may prescribe any procedures the secretary of state determines to be necessary to facilitate the casting, secrecy, and counting of provisional ballots.
