When an advance polling station closes on each of the four days of advance polling, the candidates or their representatives may take note of the serial number of the seal on the ballot box, and on the box referred to in paragraph (2)(f) that is used on that day, if any. When the advance polling station is re-opened on the 2nd, 3rd and 4th days of advance polling, they may again take note of the serial number of the seal on the box referred to in paragraph (2)(f) that was used on the previous day of voting. When the votes are counted on polling day, they may take note of the serial number of the seal on each of the ballot boxes used for advance polling.
