G.R. No. 193993 - Tan vs. Crisologo

Case Summary (G.R. No. 193993)

Factual Background

Vivenne K. Tan was born to Filipino parents on April 1, 1968 and became a naturalized U.S. citizen on January 19, 1993. On October 26, 2009, she applied to register as a voter in Quezon City and represented herself as a Filipino citizen by birth; the Election Registration Board approved her application on November 16, 2009. Tan took an Oath of Allegiance to the Republic of the Philippines on November 30, 2009, and on December 1, 2009 she filed a petition with the Bureau of Immigration for reacquisition of Philippine citizenship, executed a sworn declaration renouncing U.S. allegiance, and the Bureau of Immigration issued an order confirming her reacquisition. Tan also filed her Certificate of Candidacy for congresswoman on December 1, 2009. On November 28, 2009, Vincent "Bingbong" Crisologo filed a petition in the MeTC seeking Tan’s exclusion from the voter’s list on the grounds that she was not a Filipino citizen at the time of registration and that she failed to meet residency requirements.

MeTC Decision

The Metropolitan Trial Court, Branch 37, Quezon City rendered a decision on January 14, 2010 excluding Vivenne K. Tan from the voter’s list. The MeTC found that Tan was not a Filipino citizen when she registered on October 26, 2009 because she had previously manifested by acts and admissions that she was an American citizen. The court emphasized that Tan’s subsequent application for citizenship, taking of an Oath of Allegiance, and formal acts to reacquire Philippine citizenship showed she was not a Filipino citizen at the time of registration and concluded that her inclusion in the voter’s list was irregular.

RTC Proceedings and Rationale

Tan appealed to the Regional Trial Court, which reversed the MeTC and dismissed Crisologo’s petition for lack of merit. The RTC reasoned that any defect in Tan’s citizenship at the time of registration was cured by her subsequent acts: taking an Oath of Allegiance to the Republic of the Philippines, filing a petition under R.A. No. 9225 before the Bureau of Immigration, the Bureau’s issuance of an order granting reacquisition, and her sworn renunciation of U.S. nationality. The RTC held that Tan, having reacquired Philippine citizenship under R.A. No. 9225, was deemed not to have lost her Filipino citizenship and therefore was a valid registered voter.

Petition for Certiorari to the Court of Appeals

Because the RTC decision became final and executory pursuant to R.A. No. 8189, Vincent "Bingbong" Crisologo filed a petition for certiorari with the Court of Appeals. He argued that Tan should have been excluded from the voter registry for failing to meet the citizenship and residency qualifications required for voter registration, and he attacked the RTC’s conclusion that subsequent reacquisition cured any defect present at the time of registration.

Court of Appeals Decision

The Court of Appeals granted Crisologo’s petition, annulling and setting aside the RTC disposition and reinstating the MeTC decision excluding Tan from the voter’s list. The CA reasoned that the taking of the Oath of Allegiance required by R.A. No. 9225 is a condition sine qua non for reacquisition or retention of Philippine citizenship; that Section 2 of R.A. No. 9225 could not be read to mean Tan never lost Philippine citizenship because Section 2 applies only to citizens at the time of the statute’s passage; that R.A. No. 9225 contains no retroactivity provision applicable to persons who naturalized before its effectivity; and that one must have taken the Oath of Allegiance before one can validly register as a voter.

Issues Presented to the Supreme Court

The central question presented was whether Vivenne K. Tan was a Philippine citizen at the time she filed her voter registration application on October 26, 2009, and, relatedly, whether her subsequent reacquisition of Philippine citizenship under R.A. No. 9225 operated retroactively to cure any defect in her voter registration that existed at the time of application.

Supreme Court Ruling

The Supreme Court denied Tan’s petition for review on certiorari and affirmed the Court of Appeals decision in toto. The Court held that Tan was not a Filipino citizen at the time she registered and that R.A. No. 9225 does not operate retroactively to perfect a registration that was invalid at the time of filing.

Legal Reasoning

The Court reiterated that suffrage is reserved to Filipino citizens as provided in CONSTITUTION, Article V, Section 1, and reflected in R.A. No. 8189. The Court observed that Tan’s voter registration occurred on October 26, 2009, while her Oath of Allegiance to the Philippines and her petition for reacquisition occurred after that date on November 30 and December 1, 2009, respectively. The Court analyzed R.A. No. 9225, noting that Section 3 deems natural-born citizens who lost their citizenship by naturalization to have reacquired Philippine citizenship upon taking the prescribed oath, and that Section 2 differentiates between those who “reacquired” and those who “retained” citizenship. The Court rejected Tan’s contention that reacquisition and retention have the same retroactive effect. Relying on the plain meaning of the statute, the Court held that R.A. No. 9225 contains no retroactive provision applicable to persons who became naturalized foreign citizens before the statute’s effectivity. The Court invoked precedent on statutory construction, the principle that statutes operate prospectively unless retroactivity is clearly intended, and authorities concerning the legal effect of renunciation and naturalization, includin
