Dual Citizenship and Elective Office: The Imperative of Sworn Renunciation in Philippine Law

The Supreme Court has long held that dual citizens who wish to run for elective office in the Philippines must comply strictly with the requirements of Republic Act No. 9225, the Citizenship Retention and Re-Acquisition Act of 2003. In Sobejana-Condon v. COMELEC (G.R. No. 198742, August 10, 2012), the Court clarified that a sworn renunciation of foreign citizenship is not a mere formality—it is a mandatory requirement that cannot be substituted by an unsworn declaration or by the mere act of running for office.

The case involved Teodora Sobejana-Condon, a natural-born Filipino who became an Australian citizen in 1984. In 2005, she re-acquired her Philippine citizenship under R.A. No. 9225 by taking an oath of allegiance. A year later, she filed a Declaration of Renunciation of Australian Citizenship—but the document was not under oath. She then ran for Vice-Mayor of Caba, La Union in 2010 and won. Private respondents filed quo warranto petitions, arguing that her failure to execute a sworn renunciation disqualified her from holding office.

The Issue

The central question was whether Condon’s unsworn declaration of renunciation satisfied Section 5(2) of R.A. No. 9225, which requires those seeking elective office to make a "personal and sworn renunciation of any and all foreign citizenship before any public officer authorized to administer an oath." Condon argued that the requirement was merely pro forma and that her act of running for office already demonstrated her abandonment of Australian citizenship.

The Ruling

The Supreme Court dismissed the petition and affirmed Condon’s disqualification. The Court ruled that the language of Section 5(2) is plain and unambiguous. A dual citizen who seeks elective office must execute a sworn renunciation—an affidavit duly executed before an officer authorized to administer oaths—prior to or simultaneous with the filing of the certificate of candidacy. An unsworn declaration is ineffective.

The Court rejected the argument that the renunciation was a mere formality. While a legislator’s remark during deliberations suggested it might be pro forma, the Court explained that this statement was made in a different context—regarding whether re-acquired citizenship restores one’s status as a natural-born citizen. It did not suggest that the renunciation requirement could be dispensed with for those seeking public office.

The Court also held that the act of running for public office, by itself, does not constitute an effective renunciation. Prior rulings that treated the filing of a certificate of candidacy as an implied renunciation were superseded by R.A. No. 9225, which added the explicit sworn renunciation requirement. Furthermore, winning the election does not cure the defect of a disqualified candidacy.

Key Points on Foreign Law

The Court also addressed Condon’s argument that she had already lost Australian citizenship under Australian law. The Court noted that foreign laws are not a matter of judicial notice—they must be alleged and proven in court. Condon failed to present competent proof of the Australian Citizenship Act, and the unauthenticated letter from the Australian government was properly disregarded.

Even if the foreign law were proven, the Court emphasized that R.A. No. 9225 does not concern itself with the actual status of the other citizenship. The law requires a sworn renunciation regardless of whether the person technically remains a dual citizen under foreign law.

Practical Takeaways

• The sworn renunciation is mandatory. Dual citizens seeking elective office must execute a personal and sworn renunciation of foreign citizenship before an authorized officer, at the time of filing the certificate of candidacy.
• Unsworn declarations are invalid. A declaration of renunciation that is not under oath does not comply with Section 5(2) of R.A. No. 9225 and will result in disqualification.
• Running for office is not enough. The mere act of filing a certificate of candidacy does not substitute for the sworn renunciation required by law.
• Winning does not cure disqualification. A candidate who wins despite being disqualified cannot validly hold office; the position may be declared vacant.
• Foreign law must be proven. A party cannot rely on foreign statutes without presenting competent evidence of their existence and effect.
