11-8. When deputies may administer.
In all cases where any civil officer, in the discharge of his duties, is permitted by the law to administer an oath, the deputy of such officer, when discharging such duties, shall have authority to administer it, provided he is a sworn officer; and the oath thus administered by the deputy shall be as obligatory as if administered by the principal officer, and shall be attended with the same penalties in case of false swearing.
