Paragraph 50 Removing cancelled ballot papers from the final ballot box
Where it appears to the counting officer that a cancelled ballot paper has been placed in the final ballot box, he shall instruct a clerk who does not have access to the list of ballot numbers issued that the clerk shall, on the next occasion on which the preliminary ballot box is opened, in the presence of the agents—
open the final ballot box and retrieve the cancelled ballot paper;
show the ballot number on the cancelled ballot paper to such agents as are present;
re-lock (if it has a lock) and re-seal the final ballot box;
retrieve the security statement that relates to the cancelled ballot paper from the receptacle for security statements; and
attach the cancelled ballot paper to the security statement and place both documents in the receptacle for cancelled ballot papers.
While retrieving a cancelled ballot paper in accordance with paragraph (1), the counting officer shall keep the ballot papers face downwards, so far as practicable, and shall take all proper precautions for preventing any person from seeing the votes made on the ballot papers.
