Connecticut Statutes § 9-232m Casting of provisional ballots

Upon receipt of an application for provisional ballot, the moderator shall provide the applicant with a provisional ballot and a serially-numbered envelope and shall make a record of such issuance on the provisional ballot inventory form. The applicant shall forthwith mark the ballot in the presence of a polling place official in such manner that the official shall not know how the ballot is marked. The applicant shall then fold the ballot in the presence of the polling place official so as to conceal the markings and deposit and seal it in the serially-numbered envelope in the manner prescribed by the Secretary of the State. The polling place official shall provide such documentation to the elector so the elector may later verify whether the elector's provisional ballot was counted, and shall deposit the provisional ballot and envelope in the provisional ballot depository envelope. The elector shall then immediately leave the room. The registrars of voters shall provide a free access system restricted to the elector who cast the ballot to verify if the provisional ballot was counted, and if the ballot was not counted, the reason that the ballot was not counted.
