Manuel Natal Albelo launched a legal challenge demanding that a new election be held for the municipality's 77th Unit, which groups together several forms of absentee-voting and mail-in ballots. In his litigation, he alleged widespread irregularities during the counting process and leading to the election.[4] The lawsuit was dismissed by a judge in January 2021 due to a total lack of evidence supporting the claim.[5]
