La. Stat. tit. 38 § 1780
Immediately after the closing of the polls, the commissioners shall, in the presence of the bystanders, open the ballot boxes, count the ballots found therein, check the ballots with the list of voters kept, proceed to count the votes in number and amount, keep in duplicate tally sheet showing the votes in number in favor of and against the proposition or propositions submitted and showing the valuation of property in favor of and against the proposition. They shall make in duplicate compiled statements of the vote in number and amount, both in favor of and against each proposition or propositions. After swearing to the correctness of the numbered list of voters, the duplicate tally sheet, and duplicate compiled statements, they shall deposit the ballots, the registrar's list of voters, the numbered list of taxpayers voting, one duplicate tally sheet, and one duplicate compiled statement in the ballot box, immediately seal the ballot box and within forty-eight hours after the closing of the polls, deliver the sealed ballot box with its contents to the authorities ordering the election, and deliver the duplicate tally sheet and the duplicate compiled statement to the clerk of the district court of the parish in which the election has been held, who shall file the tally and statement in his office. If the election commissioners on counting the ballots find they do not correspond with the list of voters, they shall before examining and counting the ballots examine them for the purpose of finding the discrepancy, and if it should be found that any ballots have been duplicated they shall be destroyed, or if it be found that the name of a voter has been omitted from the list of persons voting, the name shall be added to the list.
