G.R. No. L-54114. June 28, 1983. THE PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. ARSENIO BORJA, defendant-appellant.
FACTS

Arsenio Borja was convicted of murder by the Court of First Instance of Baguio and Benguet and sentenced to life imprisonment. He appealed, assigning multiple errors, primarily challenging the credibility of eyewitnesses Mario Aticao and Julian Marinao and arguing that the evidence against him was merely circumstantial. While initially hinting that another person fired the fatal shots, Borja ultimately admitted to causing the death of the victim but invoked the exempting circumstance of accident under Article 12(4) of the Revised Penal Code. He claimed he was performing his duty as a security guard when he encountered an unidentified man. He asserted that his first shot was a warning, and the second fatal shot occurred accidentally when he slipped, his gun fell, and discharged as he squeezed the trigger.

ISSUE

Whether the trial court erred in convicting Borja of murder, specifically in rejecting his defense of accident and in crediting the testimonies of the eyewitnesses.

RULING

The Supreme Court affirmed the conviction. The legal logic centered on the inapplicability of the exempting circumstance of accident and the credibility of the prosecution’s evidence. For accident to exempt one from criminal liability, the act causing the injury must be lawful and performed with due care. The Court found Borja’s version untenable. His admitted acts—loading his rifle, cocking it, and firing at a person—were not lawful. His narrative was internally inconsistent, alternately claiming he fired due to a challenge from the unarmed victim or as a warning shot. The Court found it implausible that an unarmed man would challenge an armed guard or that a fatal shot could occur precisely as described during a slip. Borja’s conduct after the shooting, notably failing to render aid, further undermined his claim of an unintended killing.
Conversely, the eyewitness accounts were deemed credible and consistent on the material point: Borja deliberately aimed and fired at the victim. The Court noted the witnesses had no motive to falsely testify. Alleged discrepancies between their affidavits and court testimony, as well as minor contradictions between their accounts, were dismissed as trivial and inherent to the sworn statement process. Since Borja’s guilt was proven beyond reasonable doubt through direct evidence, his lack of motive became inconsequential. The assessment of damages was upheld as civil liability flows from criminal liability, which was properly established.
