N.D. Cent. Code § 40-18-14
A municipal judge may enforce due obedience to the court's orders and judgments. The judge may fine or imprison for contempt committed in the judge's presence while holding court, as well as for contempt of process issued, and of orders made by the judge. When an act or omission constituting a contempt in a municipal court is not committed in the presence of the municipal judge, an affidavit alleging the facts may be filed and a warrant of arrest thereupon may issue on which the person accused may be arrested and brought before the municipal judge immediately. The person must be given a reasonable opportunity to employ counsel and defend against the alleged contempt. After hearing the allegations and proofs, the municipal judge may discharge the person or adjudge the person guilty and may punish by fine or imprisonment or both. The fine in any case may not be more than one thousand five hundred dollars and the imprisonment may not be more than thirty days.
