N.D. Cent. Code § 20.1-03-41

If the director determines by clear and convincing evidence that a substantial violation of state or federal criminal hunting, fishing, or trapping laws of this chapter by a guide or outfitter has occurred, the director may suspend, revoke, or deny a guide or outfitter license to the person violating the laws or provisions. In such a case, a hearing must be held within ten days of the director's intended action and the person must be given notice of the hearing. The person may waive the hearing after having been notified of the person's right to a hearing, in which case the action of the director takes effect upon signing the waiver. The director may serve notice of the hearing by publication if reasonable efforts to make personal service have failed.
