(3) A ballot paper shall not be issued to a person who refuses to receive the personal mark with indelible ink or if he already bears such a mark or the remnants of such mark.
(4) If a contesting candidate or his election or polling agent alleges that an elector to whom a ballot paper is about to be issued already has one or more ballot papers in his possession, the Presiding Officer may require the elector to satisfy him that he does not have any other ballot paper in his possession and may also take such measures as he thinks fit to ensure that such elector does not insert more than one ballot paper in the ballot box.

(6) The elector shall vote without undue delay and shall leave the polling station immediately after he has inserted his ballot paper in the ballot box.
(7) Where an elector is blind or is otherwise so incapacitated that he cannot vote without the assistance of a companion, the Presiding Officer shall allow him such assistance and thereupon such elector may do with such assistance any thing which an elector is required or permitted to do under this Order.
