G.R. No. L-34973 April 14, 1988
YUNG UAN CHU, petitioner-appellee, vs. REPUBLIC OF THE PHILIPPINES, oppositor-appellant.

FACTS

Petitioner Yung Uan Chu, born in Iloilo City to Chinese parents, married Miguel Cupang Jr., a native-born Filipino citizen, in 1954. The couple had six children, all registered as natural-born Filipino citizens. Petitioner resided continuously in the Philippines, engaged in business, and demonstrated qualifications for citizenship, including proficiency in local languages, good moral character, and a lack of statutory disqualifications. She filed a petition for naturalization with the Court of First Instance of South Cotabato, which was granted by the lower court in 1971. The court found her possessed of all qualifications and authorized her to take the oath of allegiance.
The Republic, through the Solicitor General, appealed the decision. The government argued that the lower court lacked jurisdiction to declare petitioner a Filipino citizen via a petition for naturalization. The appeal centered on the procedural propriety of using a judicial naturalization proceeding to effect a declaration of citizenship allegedly already acquired by operation of law through marriage to a Filipino citizen.

ISSUE

Whether the lower court had jurisdiction to grant the petition for naturalization, which effectively sought a judicial declaration that petitioner had already become a Filipino citizen by virtue of her marriage to a native-born Filipino.

RULING

The Supreme Court affirmed the lower court’s decision but clarified the legal logic. The Court reiterated the established doctrine that there is no independent judicial action for a declaration of citizenship. Courts cannot entertain a suit whose sole objective is to obtain a pronouncement on an individual’s citizenship status, as this lies beyond judicial power absent a justiciable controversy. An alien woman who marries a Filipino citizen does not automatically become a Filipino; she must still prove the absence of disqualifications under Section 4 of Commonwealth Act No. 473 . The proper procedure for such a woman is administrative: she must file a petition with the Commission on Immigration for the cancellation of her alien certificate of registration, alleging her marriage and lack of disqualifications. Judicial recourse is available only if the Commissioner takes adverse action.
However, in this specific case, the Supreme Court found an exception. Since a full-blown judicial proceeding had already been conducted where petitioner thoroughly proved she possessed all qualifications and none of the disqualifications for citizenship, the Court deemed it unnecessary to remand the case for administrative action. The judicial record conclusively established that she was already a Filipino citizen by operation of law. Thus, while the Court upheld the doctrinal rule on the absence of a declaratory judgment for citizenship, it affirmed the lower court’s grant of the petition and directly ordered the Commissioner of Immigration to cancel petitioner’s alien certificate of registration.
