Idaho Code § 59-917

Whenever for any reason any elective official of the state, is temporarily unable to perform the duties of his office, the governor may appoint a suitable person to perform such duties temporarily as an acting officer, until the incumbent of the office shall be able to resume the performance of his duties, or a vacancy occurs in such office. The governor shall require such bonds for persons so appointed as may appear to him necessary for the protection of the state, not exceeding the bonds given by the officer in whose stead he acts. Such acting officer shall be nominated by the incumbent of the office: provided, that when the incumbent is unable or fails to so nominate, the governor may appoint without such nomination: provided further, that nothing in this section contained shall be construed to amend or repeal existing laws relating to filling vacancies in state offices. In any case involving an office, the appointment to which, at the time involved would, in case of vacancy, require the consent of the senate, the consent of the senate shall be requisite to the temporary service of the acting officer.
