87(2)If at the hour for closing of the poll there are any electors in the polling station or in line at the door, who are qualified to vote and have not been able to do so since their arrival at the polling station, the poll shall be kept open a sufficient time to enable them to vote before the outer door of the polling station is closed, but no one not actually present at the polling station at the hour for closing of the poll shall be allowed to vote, even if the poll is still open when he arrives.
