Idaho Code § 20-604

Any district judge or magistrate may order a person confined or detained, upon any grounds provided by law, in any county or municipal jail or other confinement facility within the judicial district in which the court is located. Such order may thereafter be amended to transfer such person from such jail or facility to another at any place within the judicial district. If the county in which the court is located has made an agreement with another governmental unit or agency located outside the judicial district for the confinement or detention of persons, then any district judge or magistrate acting in that county may also order a person confined or detained outside of the judicial district in the confinement facility or jail described in such agreement. All persons, officers and officials in charge of a jail or confinement facility shall accept a person for detention or confinement upon receiving a certified copy of an order made pursuant to this section.
