In precincts which use an electronic voting system or paper ballots, it is the duty of the judges of the election, immediately before the opening of the polls, to open the ballot box in the presence of the people there assembled and turn it upside down so as to empty it of everything that may be in it and then lock it securely. It shall not be reopened until the time for counting the ballots therein.
