G.R. No. 181430; March 9, 2010
FELIPE RONQUILLO y GUILLERMO and GILBERT TORRES y NATALIA, Petitioners, vs. PEOPLE OF THE PHILIPPINES, Respondent.

FACTS

Petitioners Felipe Ronquillo and Gilbert Torres were charged with Homicide before the Regional Trial Court (RTC) of Ballesteros, Cagayan. The Information alleged that on June 23, 2001, armed with a shovel and bamboo, they conspired to attack, assault, and hit Edgar Ronquillo on the head, causing his death. The prosecution established that while petitioners and Alejandro Rivera were drinking near a store, the victim passed by. A heated argument ensued between Felipe Ronquillo and the victim, leading to a fistfight. Ronquillo twice kicked the victim, who then drew a knife, hitting Ronquillo on the left thigh. Gilbert Torres joined and struck the victim on the nape with a shovel. As the victim lay unconscious, Ronquillo repeatedly hit him on the head and body with a bamboo pole. The victim died the next day from brain herniation, intracranial hemorrhage, and mauling. Petitioners interposed self-defense, claiming the victim initiated aggression by chasing Ronquillo with a knife and that Torres used the shovel to defend himself. The RTC convicted them of homicide, sentencing them to imprisonment and ordering them to pay damages. The Court of Appeals affirmed the conviction but modified the penalty and awarded temperate damages in lieu of actual damages.

ISSUE

1. Whether petitioners acted in self-defense.
2. Whether conspiracy existed in the killing of the victim.

RULING

The Supreme Court DENIED the petition and AFFIRMED the decision of the Court of Appeals.
1. On Self-Defense: The Court ruled that petitioners failed to prove the elements of self-defense. Unlawful aggression, a condition sine qua non, was absent. The prosecution witness testified that the aggression emanated from petitioner Ronquillo, who kicked the victim, prompting the victim to draw his knife in response. The victim’s mere possession of a knife did not constitute unlawful aggression, as petitioners did not establish an actual and imminent threat to their lives. The gravity, location, and number of injuries inflicted on the victim (severe head injuries and a fractured humerus) negated self-defense. Even assuming initial aggression from the victim, it ceased when he was unconscious on the ground, and petitioners’ subsequent attacks were no longer necessary. Petitioners had the opportunity to flee but did not. Ronquillo also admitted to harboring ill feelings toward the victim, further undermining the claim of self-defense.
2. On Conspiracy: The Court found the discussion on conspiracy irrelevant because petitioners admitted to the killing. Their individual acts—Torres striking the victim with a shovel and Ronquillo beating the unconscious victim with a bamboo pole—directly contributed to the death, making them co-principals. Furthermore, invoking justifying circumstances (self-defense) is incompatible with conspiracy, as the former presupposes a lack of criminal intent, while the latter presupposes a community of criminal intent. The appellate court’s appreciation of conspiracy was thus upheld.
