Diño filled up the COC for mayor, not president, and filed it with the Law Department of the Commission on Elections (Comelec) at the central office in Manila. While he changed the label of his document to “President,” he failed to alter the remaining parts of the COC to conform with the changes. Thus, despite the title “Certificate of Candidacy for President,” the sentence next to the instruction box read: “I hereby announce my candidacy for the position of MAYOR, City/Municipality of Pasay City…in the May 09, 2016 National and Local Elections.”
