Spoilt ballot

(1) A voter who has so inadvertently dealt with his ballot paper that it cannot be conveniently used as a ballot paper may, on delivering it to the presiding officer and proving the inadvertence to the satisfaction of that officer, obtain another ballot paper in place of that so delivered (hereinafter called a spoilt ballot paper). (2) The spoilt ballot papers shall immediately be cancelled at the presiding officer writing the word “cancelled” across the face and initialling it, and he shall retain the same.
