In polling places that use an electronic voting system or paper ballots, the election judges, immediately before the opening of the polls, shall open the ballot box in the presence of the people assembled in the polling place, turn it upside down so as to empty it of all of its contents, and then lock it securely. The ballot box must not be reopened until the time for counting the ballots it contains.
