Mont. Code Ann. § 32-2-1031

When the department feels that an emergency exists or is impending in this state or in any part of this state, it may, by proclamation, authorize mutual associations located in the affected area to close any of their offices. In addition, if the department is of the opinion that an emergency exists or is impending that affects or may affect a particular mutual association or mutual associations, or a particular office or offices of a particular mutual association, but not mutual associations located in the area generally, it may authorize the particular mutual association or mutual associations or office or offices so affected to close. The closed office or offices must remain closed until the department proclaims that the emergency has ended or until an earlier time that the officers of the mutual association determine that one or more of the closed offices should reopen and, in either event, for the amount of time afterward as may reasonably be required for them to reopen.
