G.R. No. L-19836 - Leng vs. Republic

Go A. Leng, a citizen of the Republic of China, was born in Amoy, China.
He arrived in the Philippines on October 6, 1938, and has maintained continuous residence since, except for a brief visit to China in 1947.
Leng filed his petition for Filipino citizenship on November 16, 1960 before the Court of First Instance of Iloilo.
His petition included a declaration of intention to become a Filipino citizen along with affidavits from his witnesses.

Original submission was supported by affidavits from Luis G. Hofilena and Patricio M. Miguel.
The petition was later amended after the death of Hofilena, with Venancio Velasco substituted as a witness.

Leng works as the Dean of Discipline and Assistant Property Custodian at the Iloilo Chinese Commercial School, earning a monthly salary of P200.00.
He also holds a part-time position at the La Paz Bijon Factory, owned by his brother-in-law, from which he earns an additional P100.00 per month.
His wife is employed as a teacher at the same school, receiving a salary of P140.00 per month.
He files income tax returns jointly with his wife and has demonstrated his economic activities through consistent tax payments.

Leng resides at his brother-in-law’s house where free board is provided.
He possesses a bank deposit amounting to P6,000.00.
He is registered as an alien with the Bureau of Immigration and holds an immigrant certificate of residence.
Educational background includes primary and elementary education at the Iloilo Commercial School and secondary studies at the Central Philippine University.

Leng is proficient in the local Visayan dialect and the English language.
He espouses the principles underlying the Philippine Constitution and has conducted himself in an irreproachable and proper manner.
He maintains cordial relations with the community, participates socially with Filipinos, and embraces local customs, traditions, and ideals.
He is not involved in subversive activities, is not a member of the communist party or any group advocating the overthrow of government, and does not condone polygamy.

The government challenged the petition on the grounds that his income was not sufficiently lucrative; his regular monthly income of P200.00 from the school and an irregular part-time income from the factory (merely alleged to bolster his economic standing) were deemed inadequate for economic stability.
Evaluations by the court and reference to previous decisions (e.g., Ong Ling Chuan vs. Republic and others) underscored that a P200.00 monthly salary is not lucrative, especially given the current cost of living.
The combined annual income of petitioner and his wife (P6,300.00) was found to be insufficient, particularly when considering financial responsibilities such as supporting a child.
Additionally, objections were raised regarding the petitioner’s use of an alias without obtaining authority under Commonwealth Act 142, Section 2, and his failure to secure the required permission from the Chinese authorities regarding his change of nationality.

Whether petitioner's declared income (P200.00 per month from his primary employment, supplemented by a part-time income) qualifies as "lucrative" under the Revised Naturalization Law.
If the additional part-time income, allegedly given only to enhance his economic appearance, can legitimately be considered in meeting the financial requirements.

Whether the petitioner’s use of an alias without the legally mandated authority under Commonwealth Act 142, Section 2, constitutes a bar to his naturalization.
Whether the petitioner adequately secured the permission of the Minister of Interior of China regarding his renunciation of Chinese citizenship and change of nationality, as required by Chinese law.

The reliability and timing of the employment evidence presented, particularly concerning his part-time work at the La Paz Bijon Factory.
Whether the evidence illustrating his economic stability and social integration suffices to meet the statutory criteria for naturalization.
