G.R. No. 136351 , July 28, 1999
Joel G. Miranda, petitioner, vs. Antonio M. Abaya and the Commission on Elections, respondents.

FACTS

Jose “Pempe” Miranda filed his certificate of candidacy for Mayor of Santiago City for the May 11, 1998 elections. Antonio Abaya filed a petition to deny due course to or cancel this certificate, which the COMELEC granted in a May 5, 1998 resolution, effectively disqualifying Jose Miranda. The following day, May 6, 1998—after the legal deadline for filing certificates of candidacy—Joel G. Miranda filed his own certificate as a substitute candidate for his father. In the elections, Joel Miranda won over Abaya. Abaya then filed a petition to declare the substitution void, arguing it was invalid because the certificate of the person being substituted (Jose Miranda) had already been cancelled.
The COMELEC First Division initially dismissed Abaya’s petition. However, on reconsideration, the COMELEC En Banc reversed this dismissal in a December 8, 1998 resolution. It annulled Joel Miranda’s substitution and proclamation, and ordered the city board of canvassers to reconvene and proclaim the winning candidate from among those voted upon. Joel Miranda elevated the case to the Supreme Court via certiorari.

ISSUE

The core issues were: (1) whether the COMELEC En Banc acted without jurisdiction or with grave abuse of discretion in annulling petitioner’s substitution and proclamation; and (2) whether it gravely abused its discretion in ordering the proclamation of the private respondent.

RULING

The Supreme Court partially granted the petition. It upheld the COMELEC’s annulment of Joel Miranda’s substitution and proclamation but nullified the portion of the COMELEC resolution directing the proclamation of another candidate.
The Court affirmed that the COMELEC acted within its jurisdiction and without grave abuse of discretion in nullifying the substitution. The legal logic centered on the proper application of Section 77 of the Omnibus Election Code, which allows substitution only if the original candidate dies, withdraws, or is disqualified. The Court ruled that the disqualification of Jose Miranda via the denial and cancellation of his certificate of candidacy was final as of May 5, 1998. Consequently, there was no valid candidacy left to substitute for when Joel Miranda filed on May 6. A substitution presupposes a valid, existing candidacy; a cancelled certificate is considered void ab initio (from the beginning). Therefore, Joel Miranda’s certificate of candidacy was itself invalid.
However, the Court modified the COMELEC’s order to proclaim the “winning candidate.” It held that the COMELEC could not simply proclaim the second-placer, Abaya, because a void substitution does not automatically make the second-placer the winner. Votes cast for a candidate with a void certificate are considered stray. Since no valid candidate remained after Jose Miranda’s disqualification, the mayoralty race effectively had no qualified candidate. Thus, the proper remedy was not to proclaim Abaya but to apply the rules on succession under the Local Government Code. The position would be filled by the Vice-Mayor. The Court emphasized it could not impose a candidate the electorate did not choose, and the legal succession rule must govern the resulting permanent vacancy.
