183. If the hearing establishes
(1) that a corrupt electoral practice was used by a candidate or, with his knowledge and consent, by another person, the candidate shall be considered guilty of a corrupt electoral practice, and if he has been elected, his election is null;
(2) that a corrupt electoral practice was used by the representative of a candidate, the election of that candidate is null.
The election of a candidate shall not be declared null pursuant to subparagraph 2 of the first paragraph if it is established that the deed is of minor gravity and could not have affected the outcome of the election, and that the candidate, in good faith, took reasonable precautions to carry on an honest campaign for election.
