When any petition is filed by qualified electors of a county or municipality requesting a vote on matters affecting all or any portion of a county or municipality, the certifying official shall post a list of all names disqualified from the petition and the reason for disqualification at the courthouse or city hall, as the case may be. A person whose signature has been disqualified by the certifying official may, within ten (10) days after said notice has been posted, appear before such certifying official and present evidence of his qualification accompanied by a notarized affidavit stating the reason that his signature is qualified for the petition. Based upon such information, the certifying official shall reconsider his disqualification and may allow the signature to be counted if such action appears justified.
