G.R. No. 177246, September 25, 2017
ANTONIO A. SOMBILON, PETITIONER, VS. PEOPLE OF THE PHILIPPINES, RESPONDENT.

FACTS

Petitioner Antonio Sombilon, then Barangay Chairman of Lanas, San Jose, Romblon, was convicted of Homicide for the fatal shooting of SPO3 Gerardo Amerilla on November 18, 1997. The prosecution’s evidence established that Sombilon was causing a commotion, firing his gun in front of Nelson Andres’s house. Upon hearing the shots, Amerilla responded to the scene. According to eyewitnesses, when Amerilla asked Sombilon what the problem was, Sombilon immediately fired at him twice, causing fatal injuries. The victim, before expiring, identified Sombilon as his assailant to another witness. The autopsy confirmed gunshot wounds caused the death.
Sombilon admitted the shooting but claimed self-defense. He testified that he went to Andres’s house to discuss a community concern about selective electricity. As he was leaving, he claimed he saw a person about 15-20 meters away aim and fire a gun at him. He asserted he returned fire in the direction of the muzzle flash, believing his life was in danger, and only later discovered he had shot Amerilla. He alleged the victim was armed, but no weapon was recovered from the crime scene.

ISSUE

Whether the petitioner successfully proved the justifying circumstance of self-defense.

RULING

No. The Supreme Court affirmed the conviction, holding that the petitioner failed to prove the essential element of unlawful aggression. Self-defense requires clear and convincing proof of three elements: (1) unlawful aggression by the victim; (2) reasonable necessity of the means employed to prevent or repel it; and (3) lack of sufficient provocation from the person defending himself. Unlawful aggression is the indispensable precondition; without it, there can be no valid self-defense.
The Court found Sombilon’s claim of unlawful aggression to be unconvincing and unsupported by the evidence. His testimony that an unidentified person fired at him from a distance was deemed implausible. The location and nature of the victim’s wounds contradicted a scenario of a sudden, long-range attack requiring defensive firing. Crucially, no firearm was recovered from Amerilla or the scene, severely undermining the claim that the victim initiated aggression. The positive and consistent testimonies of prosecution witnesses, who saw Sombilon shoot an unarmed and inquiring victim, were given greater weight. The Court emphasized that the test for unlawful aggression is whether the victim’s act put the defender’s life or personal safety in real peril, not an imagined threat. Sombilon’s claim constituted an imaginary threat, not a real peril justifying lethal force. Since unlawful aggression was not established, the defense of self-defense necessarily fails. The Court modified the penalty to an indeterminate sentence of eight (8) years and one (1) day of prision mayor, as minimum, to fourteen (14) years, eight (8) months and one (1) day of reclusion temporal, as maximum.
