Mont. Code Ann. § 3-1-518

3-1-518 . Hearing on contempt not committed in immediate view and presence of court or judge at chambers. (1) When a person arrested for a contempt not committed in the immediate view and presence of the court or judge at chambers has been brought up or appeared, the court or judge shall proceed to investigate the charge, shall schedule and hold a hearing on any answer that the person arrested may make to the charge, and may examine witnesses for or against the person, for which an adjournment may be had from time to time, if necessary. The judge investigating the charge and scheduling and presiding over the hearing may not be the judge against whom the contempt was allegedly committed, except that if the contempt arose from the violation of an order of the court issued after a hearing on the merits of the subject of the order, the judge who issued the order may punish the contempt or compel compliance with the order unless it is shown that the judge would not be impartial in addressing the contempt.

(2) The charged person must be given a reasonable opportunity to obtain counsel and prepare a defense or explanation prior to the hearing. The charged person may testify and call witnesses at the hearing.
