297. Except that no elector shall be obliged to state for whom he voted at any election, no person shall be excused from answering any question put to him in any prosecution or in any civil action or proceeding, in any court, or before any judge, touching or concerning any election, or the conduct of any person thereat, or in relation thereto.
Nevertheless, no answer given by any person claiming to be excused on the ground of privilege shall be used in any prosecution, or in any action or civil proceeding against such person if the judge or president of the tribunal gives to the witness a certificate that he claimed the right to be excused on such ground, and made answers which, in the opinion of the court or judge were full and true answers.
