Labo vs. COMELEC

The Court held that citizenship is a continuing qualification for holding public office; loss thereof during incumbency results in forfeiture of the title to the office. The Court further ruled that naturalization in a foreign country, coupled with an oath of allegiance renouncing other allegiances, constitutes a loss of Philippine citizenship under Commonwealth Act No. 63. Such citizenship may only be reacquired through the specific modes provided by law, such as repatriation, and not merely by election to public office.

Ramon L. Labo, Jr. was proclaimed mayor-elect of Baguio City on January 20, 1988. Private respondent Luis L. Lardizabal filed a petition for quo warranto with the COMELEC on January 26, 1988, contesting Labo's eligibility on the ground that he was not a Filipino citizen. The core factual dispute centered on Labo's acquisition of Australian citizenship in 1976, his subsequent use of an Australian passport, and his registration as an alien in the Philippines in 1980.

Petitioner Ramon L. Labo, Jr. was proclaimed mayor-elect of Baguio City on January 20, 1988. On January 26, 1988, private respondent Luis L. Lardizabal filed a petition for quo warranto with the COMELEC, alleging Labo was not a Filipino citizen. The petition was initially treated as a pre-proclamation controversy. The filing fee was paid on February 10, 1988, after the COMELEC re-characterized the case as a quo warranto proceeding. Evidence showed Labo was naturalized as an Australian citizen on July 28, 1976, taking an oath that renounced "all other allegiance." He subsequently used an Australian passport, registered as an alien in the Philippines in 1980, and in sworn statements declared himself an Australian citizen. A 1982 COMELEC decision found him to be a Filipino citizen, but a 1988 Commission on Immigration and Deportation (CID) decision, based on official Australian government statements, held he was an Australian citizen.

• Petitioner argued the COMELEC lacked jurisdiction because the quo warranto petition was filed beyond the ten-day reglementary period under Section 253 of the Omnibus Election Code. He contended the petition was deemed filed only upon payment of the docket fee on February 10, 1988, which was twenty-one days after his proclamation.
• He cited COMELEC Rule 36, Section 5, and jurisprudence like Manchester v. Court of Appeals to assert that payment of the filing fee is an indispensable requirement for a petition to be considered filed.
• On the merits, he argued his Australian naturalization did not automatically divest him of Philippine citizenship and that, at most, he was a dual citizen. He also invoked the doctrine of res judicata based on the 1982 COMELEC decision.

• Respondent COMELEC and private respondent argued the petition was timely. The filing fee was paid on February 10, 1988, immediately upon notice that the case was re-docketed as quo warranto. The period for filing a quo warranto petition was suspended while the matter was treated as a pre-proclamation controversy under Section 248 of the Omnibus Election Code.
• They contended the COMELEC rules and resolutions requiring a filing fee for quo warranto petitions were not yet effective when the petition was filed in January 1988.
• On the merits, they presented evidence, including official statements from the Australian government, that Labo was naturalized as an Australian citizen in 1976 and remained one. They argued this constituted a loss of Philippine citizenship under CA No. 63.

• Procedural Issues: Whether the COMELEC acquired jurisdiction over the quo warranto petition, specifically whether the petition was filed within the ten-day reglementary period despite the filing fee being paid after the proclamation date.
• Substantive Issues: Whether petitioner Ramon L. Labo, Jr. was a Filipino citizen at the time of his election and proclamation, and consequently, whether he was qualified to hold the office of Mayor of Baguio City.

• Procedural: The Court ruled the COMELEC had jurisdiction. The quo warranto petition was filed on time. The payment of the filing fee on February 10, 1988, was deemed timely because the period was suspended while the COMELEC treated the petition as a pre-proclamation controversy. Furthermore, the Court noted that the specific COMELEC resolution requiring the fee for quo warranto petitions (Res. No. 1996) took effect only on March 3, 1988, after the fee was paid.
• Substantive: The Court ruled petitioner was not a Filipino citizen. His voluntary naturalization in Australia in 1976, which required an oath of allegiance renouncing all other allegiance, constituted a clear and positive act of renouncing Philippine citizenship under CA No. 63. The Court rejected the argument that he was a dual citizen, noting the constitutional policy against dual allegiance. The Court further held that Philippine citizenship, once lost, can only be reacquired through the specific statutory modes (direct act of Congress, naturalization, or repatriation), none of which Labo had complied with. Therefore, he was ineligible for the office of mayor.

• Continuing Qualification for Public Office — The qualifications for holding a public office must be possessed not only at the time of election or appointment but must continue throughout the officer's tenure. Loss of a qualification, such as citizenship, results in automatic forfeiture of the right to hold the office.
• Loss of Citizenship by Naturalization in a Foreign Country — Under Commonwealth Act No. 63, as amended, Philippine citizenship is lost, inter alia, by naturalization in a foreign country. The formal act of taking an oath of allegiance to a foreign state, which includes a renunciation of other allegiances, is a definitive and voluntary act that severs the bond of Philippine citizenship.
• Inapplicability of Res Judicata to Citizenship — The doctrine of res judicata does not apply to decisions on citizenship because citizenship is a matter of public interest and the State is not bound by a prior judgment against it in a proceeding to which it was not a formal party.
• Principle of Liberal Construction in Election Cases to Determine the Will of the Electorate — While technical rules should not strictly apply in election cases to give effect to the will of the people, this principle cannot override a constitutional and statutory disqualification like alienage. The electorate cannot validate the election of a person disqualified by law.

• "Philippine citizenship is not a cheap commodity that can be easily recovered after its renunciation. It may be restored only after the returning renegade makes a formal act of re-dedication to the country he has abjured and he solemnly affirms once again his total and exclusive loyalty to the Republic of the Philippines. This may not be accomplished by election to public office." — This passage underscores the Court's view on the gravity of renouncing citizenship and the strict requirements for its reacquisition.
• "The electorate had no power to permit a foreigner owing his total allegiance to the Queen of Australia, or at least a stateless individual owing no allegiance to the Republic of the Philippines, to preside over them as mayor of their city. Only citizens of the Philippines have that privilege over their countrymen." — This emphasizes that constitutional and statutory qualifications for public office cannot be waived or overridden by the electorate's vote.

• Manila v. Court of Appeals — Cited by petitioner for the doctrine that the timely payment of the docket fee is mandatory for a court to acquire jurisdiction. The Court distinguished it by invoking the special circumstances of this election case and the subsequent ruling in Sun Insurance.
• Sun Insurance Office, Ltd. v. Asuncion — Cited by the Court to support the principle that while jurisdiction requires payment of the prescribed filing fee, the court may allow payment within a reasonable time under certain circumstances.
• Tañada v. Tuvera — Cited to reject petitioner's argument that COMELEC resolutions took effect immediately upon approval, reiterating the constitutional requirement of publication for due process.
• Santos v. Commission on Elections — The Court explicitly reversed its 1985 ruling in this case, which had allowed the second-place candidate to be proclaimed winner after the winner's disqualification.
• Geronimo v. Ramos and Topacio v. Paredes — The Court reaffirmed and reverted to the doctrine established in these earlier cases, holding that the candidate who places second in an election is not automatically entitled to be declared the winner when the winning candidate is disqualified. The votes cast for a disqualified candidate in good faith are not considered stray.

• Section 253, Omnibus Election Code — Provides the ten-day period after proclamation within which to file a quo warranto petition against a local official on the ground of ineligibility.
• Commonwealth Act No. 63, as amended by PD No. 725 — Enumerates the ways in which Philippine citizenship may be lost (e.g., naturalization in a foreign country) and reacquired (e.g., by repatriation).
• Section 42, Local Government Code — Sets forth the qualifications for elective local officials, including citizenship.
• Article IV, Section 5, 1987 Constitution — States that "Dual allegiance of citizens is inimical to the national interest and shall be dealt with by law."
• Article V, Section 1, 1987 Constitution — Provides that suffrage may be exercised by citizens of the Philippines, a requirement Labo failed to meet.

• Justice Hugo E. Gutierrez, Jr. — Concurred in the result but expressed reservations about the Court bypassing procedural obstacles to decide the citizenship issue directly. He limited his concurrence to cases involving citizenship and disloyalty, not other grounds for disqualification. He acknowledged Labo's achievements as mayor but concluded that a pragmatic approach was necessary because a non-citizen cannot legally hold the office.
