G.R. No. 170603 ; January 29, 2007
Edison So, Petitioner, vs. Republic of the Philippines, Respondent.

FACTS

Petitioner Edison So, a Chinese citizen born and residing in Manila, filed a Petition for Naturalization under Commonwealth Act No. 473 (the Revised Naturalization Law). He alleged possessing all legal qualifications: birth and continuous residence in the Philippines, gainful employment, good moral character, ability to speak English and Tagalog, enrollment in schools teaching Philippine history and government, and a sincere desire to embrace Filipino customs. The petition was published, and no opposition was filed. During the hearing, So and his two witnesses testified to his qualifications and irreproachable conduct. The Regional Trial Court (RTC) granted the petition.
The Republic appealed. The Court of Appeals (CA) reversed the RTC decision, finding that So failed to prove his income was lucrative and that he had a sincere desire to learn Filipino customs. The CA noted his annual income was only P100,000 and that his witnesses’ testimonies on his social mingling were vague and insufficient. So filed a Motion for Reconsideration, which was denied, prompting this Petition for Review.

ISSUE

Whether the Court of Appeals erred in reversing the RTC’s grant of naturalization to Edison So.

RULING

No, the Court of Appeals did not err. The Supreme Court affirmed the CA’s denial of the petition for naturalization. The legal logic rests on the principle that naturalization laws are to be construed strictly in favor of the State, and the burden of proof rests heavily on the applicant to show strict, complete, and full compliance with all statutory requirements.
The Court found So failed to meet two critical qualifications under C.A. No. 473 . First, he did not prove he had a lucrative trade or profession. An annual income of P100,000, even with free board, was deemed insufficient to be considered “lucrative,” as it did not convincingly demonstrate the capacity to support himself and any future family adequately. Second, the evidence of his social mingling and sincere desire to embrace Filipino customs was inadequate. The testimonies of his witnesses were general, perfunctory, and lacked specific instances of active integration into Filipino community life. Mere presence at social functions and observance of holidays are insufficient; the law requires a genuine, demonstrated effort to assimilate. Since naturalization is a privilege, not a right, any doubt must be resolved against the applicant. So’s failure to conclusively prove compliance with these requirements justified the denial of his petition.
