La. Stat. tit. 38 § 1852
The registrar of voters shall furnish to the election commissioners appointed to hold the elections a list of the taxpayers entitled to vote, together with the valuation of each taxpayer's property, as shown by the assessment roll last made and filed prior to the election. When any taxpayer's name and valuation of property has been omitted from the list or erroneously entered thereon, the commissioners of election may receive affidavits of the taxpayer's right to vote and the proper assessed valuation of his property, which affidavits shall be attached to the taxpayer'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 be established that voters were thereby deprived of votes sufficient in number and amount to have changed the result of the election.
