G.R. No. L-17748; November 28, 1962
IN THE MATTER OF THE PETITION TO BE ADMITTED A CITIZEN OF THE PHILIPPINES, MANUEL YU, petitioner-appellant, vs. REPUBLIC OF THE PHILIPPINES, oppositor-appellee.

FACTS

Manuel Yu, born in Manila in 1934 to Chinese parents, filed a petition for naturalization in the Court of First Instance of Manila. He presented evidence establishing his continuous residence in the Philippines, good moral character, and lack of any disqualifying criminal record or affiliation with subversive groups. He demonstrated proficiency in English and Tagalog, belief in Philippine constitutional principles, and that China, his country of allegiance, grants Filipinos a reciprocal right to naturalize. The trial court, however, denied his petition solely on the ground that he failed to prove possession of a lucrative lawful occupation, a statutory requirement for naturalization.
The evidence regarding his employment showed that Yu worked as a sales representative for the Victory Steel Chair Factory, owned by his mother, with an alleged annual salary of P1,440.00 or P120.00 monthly. His proof of income consisted of his own testimony and his mother’s sworn written statement, but his mother did not testify to verify this employment arrangement when she took the stand. Yu argued that the value of free board and lodging provided by his mother, estimated at P60.00 monthly, should be added to his cash salary.

ISSUE

Whether or not Manuel Yu possessed a lucrative lawful occupation to qualify for Philippine naturalization.

RULING

The Supreme Court affirmed the denial of the petition, holding that Yu failed to satisfy the lucrative income requirement. The Court applied a strict standard of proof for employment within a family-owned business, requiring “more satisfactory proof” than presented to eliminate suspicion that the employment was a mere convenient arrangement fabricated to meet the naturalization criteria. Yu’s evidence, relying on an unverified affidavit from his mother, was deemed insufficient.
On the substantive issue of lucrativeness, the Court ruled that even accepting his claimed cash salary of P120.00 monthly, such an amount was not lucrative. Citing contemporary jurisprudence, the Court emphasized that the assessment must consider the high cost of living and the diminished purchasing power of the currency. The Court rejected Yu’s argument to include the value of free board and lodging, noting that even a total monthly equivalent of P180.00 would still be insufficient, as prior rulings had held amounts as high as P250.00 monthly to be non-lucrative for naturalization purposes. Consequently, the absence of this indispensable qualification warranted the dismissal of his petition.
