89. The voter, on receiving his ballot paper, shall forthwith enter one of the compartments of the poll. He shall there mark his ballot paper, making a cross with a black lead pencil within the blank space opposite the name of the candidate in favour of whom he wishes to vote; he shall then fold the ballot paper so that the initials and the number written by the presiding officer can be seen without opening it. He shall then return his ballot paper to the presiding officer.
The latter shall, without unfolding the ballot paper, first ascertain by examining his initials and the number marked on the counterfoil that it is the same ballot paper as he furnished to the voter; then, in full view of all those present, including the voter, he shall detach the counterfoil, destroy it and place the ballot paper in the ballot box, which must be on a table in full view of all the persons present.
A voter who has inadvertently marked, spotted or torn his ballot paper so that it cannot conveniently be used may, on returning it to the presiding officer, obtain another in its place.
The presiding officer shall cancel the first ballot paper by writing thereon the word “null” with his initials.
