La. Stat. tit. 38 § 1775
The registrar of voters shall furnish the election commissioners appointed to hold the elections with a list of the land owners entitled to vote, together with the number of acres of each land owner entitled to vote as shown by the assessment roll made and filed prior to the election. When any land owner's name or the number of acres shall be omitted from the list or erroneously entered thereon the commissioners of election may receive affidavits of the land owner entitled to vote and the number of acres owned by him, which affidavit shall be attached to the voter's ballot. No defect or irregularity in or omission from the list of voters furnished by the registrar of voters hereunder shall affect the validity of the election, unless it shall be established that voters were deprived of votes sufficient in number or in number of acres to have changed the result of the election.
