 When a scrutiny is conducted, the election judge may order a vote to be struck off if the voter was not on the register of electors assigned to the polling station at which the vote was recorded or was not authorised to vote at the station; if the vote was obtained by bribery, treating or undue influence; if the voter committed or induced someone to commit the offence of personation; if the voter cast a vote at a general election in more than one electoral division; and if the vote was for a disqualified candidate and the disqualification was either a matter that the voter was aware of or was sufficiently publicised or widely known.During a scrutiny, a tendered vote that is shown to be valid will be added to the poll if any party to the proceedings asks for the vote to be added.On the other hand, a registered elector's vote will not be struck off at a scrutiny just because he was not qualified to be on the electoral register, and the returning officer's decision as to whether or not a ballot paper should be rejected may not be questioned.
