Paragraph 46 Spoilt ballot papers
A voter who has inadvertently dealt with his ballot paper at an Assembly election in such manner that it cannot be conveniently used as a ballot paper may, on delivering it to the presiding officer and proving to his satisfaction the fact of the inadvertence, obtain another ballot paper in the place of the ballot paper so delivered (in this Schedule referred to as “a spoilt ballot paper”), and the spoilt ballot paper shall be immediately cancelled.
