Mont. Code Ann. § 7-31-2101

Whenever the governor issues a proclamation declaring that an emergency exists in any county requiring the relief of suffering of the inhabitants caused by famine, destitution, conflagration, or other public calamity, the board of county commissioners of the county may transfer to the proper fund to be used for purposes of relief any money in any other fund or funds of the county, but money belonging to any bond sinking or interest fund or any school fund may not be transferred. The governor shall in the proclamation state the facts upon which the emergency is declared and shall specifically limit the time during which the transfers may be made.
