G.R. No. L-2998 May 23, 1951
The People of the Philippines, plaintiff-appellee, vs. Joaquin Flavier, defendant-appellant.

FACTS

The defendant-appellant, Joaquin Flavier, was convicted of treason by the Court of First Instance of Quezon and sentenced to life imprisonment, a fine, and legal accessories. The information contained ten counts, but he was found guilty only of counts 1, 2, 7, 8, and 10. Count 1 accused him of aiding the Japanese Imperial Forces by serving as an officer of the United Nippon Organization in Lopez, Tayabas, to counteract guerrillas and American liberation forces. Count 2 charged him with killing three guerrillas (Monosea, Talavera, and Ramos) in Lopez, Tayabas. Count 7 involved the arrest of Florentino Salumbides on suspicion of being a guerrilla spy, leading to his 22-day detention. Count 8 pertained to the arrest and torture of Gerundio Villanesa (also referred to as Villanisa) on similar suspicion. Count 10 alleged the arrest of Aniceto Iglesia on suspicion of being a guerrilla. The appellant contested his conviction, arguing that his Filipino citizenship was not proven and that the evidence for the overt acts was insufficient.

ISSUE

The main issues are: (1) Whether the appellant’s Filipino citizenship was duly proven; and (2) Whether the evidence sufficiently supports his conviction for the overt acts of treason in counts 1, 2, 7, 8, and 10.

RULING

The Supreme Court affirmed the conviction, but modified it regarding the counts. On the issue of citizenship, the Court held that the appellant’s Filipino citizenship was satisfactorily proven by the official record from the Bureau of Prisons (Exhibit “A”) and the testimony of witnesses who knew him to be born in the Philippines of Filipino parents. The Court rejected his pretense of ignorance about his parents’ citizenship as absurd, given his education and former roles as a teacher and political candidate. The cited case of Jose Tan Chiong vs. Secretary of Labor was deemed inapplicable.
Regarding the overt acts, the Court found count 1 not duly proven. However, it upheld the conviction on the other counts. For count 2, while no direct proof showed the appellant killed the three guerrillas, evidence from multiple witnesses established his participation in the encounter on the enemy’s side, making him criminally liable. For count 7, the testimony of Florentino Salumbides and his brother Dominador was deemed credible, and the Court attributed a reference to “Lamberto San Juan” in the transcript as a clerical error. For count 8, the arrest of Gerundio Villanisa by the appellant was confirmed by Villanisa and another witness; the appellant’s presence and conjunction with Lamberto San Juan did not exculpate him, and the hold-up of Japanese trucks was considered a guerrilla activity. For count 10, the arrest and torture of Aniceto Iglesia by the appellant’s order were testified to by Iglesia and David Villapane, and the appellant’s involvement as a companion of Profirio Jimenez was established. The appealed judgment was affirmed with costs.
