Dual Citizenship by Birth vs. Naturalization: Election Eligibility in the Philippines

The Supreme Court’s 2022 ruling in Gana-Carait v. Commission on Elections (G.R. No. 257453) clarifies a recurring question in Philippine election law: when must a dual citizen renounce foreign citizenship to qualify for public office? The decision draws a crucial line between dual citizens by birth and those by naturalization, with significant consequences for candidates holding foreign passports.

The Case Background

Mariz Lindsey Tan Villegas Gana-Carait filed her certificate of candidacy (CoC) as Member of the Sangguniang Panlungsod of Biñan, Laguna for the May 2019 elections. She was born in Makati City to a Filipino father and an American mother. A Consular Report of Birth Abroad (CRBA) showed she acquired US citizenship at birth, and she had used a US passport for travel.

Two petitions were filed against her before the Commission on Elections (COMELEC): one for disqualification and another to cancel her CoC for alleged material misrepresentation. The COMELEC First Division cancelled her CoC, ruling that she was a dual citizen by naturalization and had failed to comply with the twin requirements of Republic Act No. 9225—taking an oath of allegiance to the Republic and renouncing her foreign citizenship. The COMELEC En Banc affirmed.

The Issue

The central question was whether Gana-Carait was a dual citizen by birth or by naturalization. This distinction determines whether she needed to personally renounce her US citizenship before running for office.

The Ruling

The Supreme Court granted the petition and set aside the COMELEC’s resolution, holding that Gana-Carait was a dual citizen by birth, not by naturalization.

The Court explained that R.A. 9225 applies only to natural-born Filipinos who became foreign citizens through naturalization—a legal process by which a State adopts an alien as a citizen. Since Gana-Carait acquired US citizenship at birth, she never underwent naturalization. The CRBA itself stated she “acquired United States Citizenship at birth,” and the submission of documents merely confirmed that fact.

The Court also noted that Philippine courts do not take judicial notice of foreign laws. The COMELEC should not have relied on provisions of the US Immigration Nationality Act without proper proof. Moreover, even if positive acts were performed to establish her US citizenship, these were done by her American parent, not by her.

Key Legal Principles

The decision affirms that dual citizens by birth are not required to renounce foreign citizenship to run for office. The mere filing of a CoC carries an implied renunciation of foreign citizenship. Only dual citizens by naturalization must comply with the twin requirements of R.A. 9225.

The Court further clarified that even a failure to renounce foreign citizenship under R.A. 9225 does not render a candidate ineligible. It is a disqualification under the Local Government Code, not a ground to cancel a CoC for material misrepresentation. The Court noted that a petition for disqualification had been filed against Gana-Carait but was dismissed and not appealed.

Practical Takeaways

• Know your category. Dual citizens by birth—those who acquired foreign citizenship automatically at birth due to their parents’ status—need not renounce foreign citizenship before running for office.
• Naturalization triggers the twin requirements. Only natural-born Filipinos who later became foreign citizens through naturalization must take an oath of allegiance and personally renounce foreign citizenship.
• A foreign passport is not automatically disqualifying. Using a US passport does not, by itself, prove that a candidate is a dual citizen by naturalization.
• Foreign laws must be proven. Philippine courts will not take judicial notice of foreign statutes; parties must present them as evidence.
• Failure to renounce is a disqualification, not a CoC defect. This distinction matters because disqualification and cancellation of CoC are separate remedies with different rules.
