If there is a vacancy in the polling place staff during voting hours: the local board may fill the vacancy with a substitute election judge who has been recruited and trained; or an election judge who is present at the polling place may fill the position of the absent election judge by appointing a person registered with the same party affiliation as the absent election judge. If a substitute election judge is appointed under subsection (a) of this section: either the election director, the election director’s designee, or the election judge making the substitute appointment shall administer the oath required under § 10-204 of this title; and a chief election judge shall document any change in the polling place staff in the records of the polling place.
