G.R. No. L-23511 and L-23512 January 31, 1974
THE PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. MORI (BILAAN) and OTO (BILAAN), accused-appellants. THE PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. LAPNAYAN BILAAN, TIWARO BILAAN, TOT BILAAN, MONGKIL and POK BILAAN, accused-appellants.

FACTS

The case involves the appeal of several Bilaans convicted for the murders of Teresita Luad, her infant Leticia, and Martina Culao. The prosecution’s case, as accepted by the trial court, rested primarily on the eyewitness account of Pio Diamante. He testified that on September 2, 1958, while in a garden near the victims’ house in Sulop, Davao del Sur, he saw the appellants, armed with guns and krises, emerge and attack. He witnessed Mori fire the initial shot, hitting Teresita. He then saw appellants Oto, Mori, Tiwaro, Lapnayan, and Mongkil ascend the house, after which he heard Martina’s cries and sounds of hacking. After the assailants left, Diamante found the three victims dead with severe wounds; Teresita and the baby were nearly decapitated, and Martina, who was pregnant, had her abdomen almost severed.
The defense consisted of alibis, which the trial court rejected, finding the prosecution witnesses credible. The court convicted the appellants of three counts of murder, imposing three penalties of reclusion perpetua on each, considering them as non-Christians, and ordering indemnity. During appeal, Mongkil died and Pok withdrew his appeal. The remaining appellants challenged the verdict, arguing the trial court erred in crediting the prosecution’s evidence and rejecting their alibis.

ISSUE

The core issue is whether the trial court erred in convicting the appellants based on the credibility of the prosecution witnesses and in rejecting their defense of alibi.

RULING

The Supreme Court affirmed the convictions. The ruling hinges on the well-established principle that factual findings of the trial court, particularly on witness credibility, are accorded high respect and are generally binding on appeal, absent any showing of overlooked material facts. The Court found no reason to deviate from this rule, as the trial judge was in the best position to assess the demeanor and truthfulness of Pio Diamante, whose testimony was clear, consistent, and provided a coherent narrative of the coordinated attack. The defense of alibi, being inherently weak, could not prevail over this positive identification.
The legal logic for the murder classification is rooted in the presence of qualifying circumstances. The killings were attended by treachery (alevosia), as the attack was sudden and employed means that ensured the defenseless victims had no opportunity for resistance. The killing of the infant Leticia was, by its nature, downright murder. The Court also noted the aggravating circumstance of dwelling, as the crimes were committed in the victims’ home. However, the trial court correctly imposed reclusion perpetua instead of the death penalty by applying Section 106 of the Administrative Code of the Department of Mindanao and Sulu, which mandates special consideration for the degree of enlightenment and customs of non-Christian accused. The Court modified the judgment by increasing the civil indemnity for each victim to P12,000 and declaring solidary liability among the appellants. Conspiracy was implied from the appellants’ collective and concerted actions, making each liable for all three crimes.
