G.R. No. 233800 - People vs. Pantallano

Petitioner, Mateo Quinga Chua, sought to be admitted as a Filipino citizen.
He claimed to be single and employed as a bookkeeper at the China Bazar in Tacloban City.
His compensation included an annual salary of P2,400.00 plus board and lodging allowances of P1,200.00.
He professed competence in both English and the Waray dialect.
His educational background was detailed, having attended the Holy Infant Academy and St. Paul’s College where he acquired elementary, secondary, and college education that covered Philippine History, Civics, and Government.
Petitioner asserted that his education and conduct, as well as mingling socially with Filipinos, rendered him qualified for citizenship irrespective of his nationality, race, or creed.
It was also established that he was born in the Philippines on September 21, 1932.

Notice of the naturalization petition hearing was published in the Official Gazette (June 19, 26 and July 3, 1961).
Additional publication appeared in the newspaper “La Nacion” in its issues dated April 8, 15, and 22, 1961.
Two character witnesses testified in court, supporting the petitioner’s claim of having an irreproachable moral character.

The trial court found that petitioner had satisfactorily demonstrated compliance with the statutory qualifications for naturalization.
Consequently, the court granted his petition for naturalization.

The City Fiscal, representing the Solicitor General, opposed the decision by arguing that petitioner did not fully comply with the law.
The opposition centered on the following points:

The failure to post the notice of hearing in the office of the Clerk or in the building housing the office, as explicitly required by the Naturalization Law.
Insufficient evidence proving that the petitioner had a lucrative trade, income, or profession, given the inadequacy of the claimed income in the context of modern living expenses.
The reliability of the character witnesses’ testimony was called into question.

The petitioner had contended that the duty to post the notice fell upon the Clerk of Court, and thus a presumption of due compliance was justified.

It was admitted that no evidence was produced to demonstrate that the notice of hearing was posted in a public and conspicuous place as mandated.
Testimony regarding the petitioner’s net annual income of P2,400.00 (exclusive of board and lodging allowances) was scrutinized against his income tax returns, which reflected a lower income.
This discrepancy suggested either the absence of such income or the commission of fraud or falsity in the tax returns.

Whether the failure to provide positive proof of posting the notice of hearing in the mandated public venue constitutes a jurisdictional defect.
Can the duty of posting be excused by presuming that the Clerk of Court fulfilled his obligations?

Whether the petitioner sufficiently demonstrated that he possessed a lucrative trade, income, or profession given the challenges raised regarding his reported income.
Whether the petitioner’s character witnesses provided a reliable and sufficient basis to support his assertion of irreproachable moral character.

Does the rule requiring posting of the notice, being a jurisdictional matter, allow for mere presumption or must there be positive evidence of compliance with this requirement?
What is the impact of discrepancies between the petitioner’s claimed income and his income tax returns on his qualification for naturalization?
