N.D. Cent. Code § 27-10-11
When a person accused of contempt is arrested upon a warrant of attachment, the sheriff, if the amount of the undertaking for the appearance of the accused is not endorsed on the warrant, or if such an endorsement is made and an undertaking is not given as prescribed in section 27-10-10, shall keep the accused in custody until the further direction of the court. When from sickness or other cause the accused is physically unable to attend before the court, that fact is a sufficient excuse to the sheriff for not producing the accused as required by the warrant. In that case, the sheriff shall produce the accused as directed by the court after the accused becomes able to attend. The sheriff in any case need not confine the accused in prison or otherwise restrain the accused except so far as is necessary in order to secure the accused's personal attendance.
