11.—(1) If a voter has inadvertently dealt with his ballot paper in such manner that it cannot be conveniently used as a ballot paper (referred to as “a spoilt ballot paper”) he may return (either by hand or by post) to the ballot holder the spoilt ballot paper.
(2) On receipt of the spoilt ballot paper, the ballot holder shall issue another ballot paper, except where those documents are received later than 3 working days before the day of the ballot.
(3) The spoilt ballot paper shall be immediately cancelled.
(4) Where a voter applies in person, the ballot holder may hand a replacement ballot paper to him instead of delivering it in accordance with paragraph 10.
