Mamangun v. People
REITERATIONFacts
The Antecedents: On July 31, 1992, a robbery-holdup was reported in Brgy. Calvario, Meycauayan, Bulacan. Police officers, including petitioner PO2 Rufino S. Mamangun, were dispatched to the scene. They entered the rooftop of a house where a suspect was reportedly hiding. While searching the rooftop, petitioner Mamangun fired his handgun once, hitting Gener M. Contreras, who was not the robbery suspect. Contreras died from the gunshot wound. Procedural History: Petitioner Mamangun was charged with Murder before the Sandiganbayan. The Sandiganbayan convicted him of Homicide, finding that the killing was not qualified by treachery, evident premeditation, or abuse of superior strength. The Sandiganbayan rejected the claim of self-defense but considered the incomplete justifying circumstance of acting in the performance of duty and the mitigating circumstance of voluntary surrender. The Petition: Petitioner sought reversal of the Sandiganbayan decision, arguing that the shooting was justified under Article 11, paragraph 5 of the Revised Penal Code (performance of duty) because he was repelling an unlawful attack by Contreras with a steel pipe.
Issue(s)
Whether the shooting of Gener M. Contreras by petitioner Rufino S. Mamangun was justified under Article 11, paragraph 5 of the Revised Penal Code (performance of duty), considering the necessity of the action. Whether the petitioner acted in self-defense when he shot Gener M. Contreras, specifically addressing the element of unlawful aggression.
Ruling
The Supreme Court affirmed the Sandiganbayan's decision, finding petitioner Rufino S. Mamangun guilty of Homicide. The Court ruled that the shooting was not justified under the performance of duty because the injury was not a necessary consequence of such duty, and there was no unlawful aggression from the victim to warrant self-defense.
Ratio Decidendi
On the issue of justification under Article 11, paragraph 5 of the Revised Penal Code: The Court held that while petitioner was performing his duty as a police officer responding to a reported crime, the shooting of Gener Contreras was not a necessary consequence of the due performance of such duty. The evidence did not support the claim that Contreras attacked petitioner with a steel pipe. The Sandiganbayan's findings indicated that Contreras was unarmed and had already stated he was not the suspect before being shot. Petitioner's claim of being attacked was deemed a mere afterthought. The trajectory of the bullet contradicted the claim of facing an attack. Therefore, the first requisite of acting in the performance of duty was met, but the second requisite, that the injury be a necessary consequence, was not. This resulted in an incomplete justifying circumstance, which is a privileged mitigating circumstance. On the issue of self-defense: The Court reiterated that a primary element of self-defense is unlawful aggression. In this case, the evidence did not establish any unlawful aggression on the part of Gener Contreras. The prosecution's eyewitness testified that Contreras exclaimed "Hindi ako, hindi ako!" before being shot, and petitioner even responded with "Anong hindi ako?" before firing. The defense's claim that Contreras suddenly turned and attacked petitioner with a steel pipe was found to be incredible. The absence of unlawful aggression meant that self-defense, whether complete or incomplete, could not be appreciated.
Main Doctrine
The justifying circumstance of fulfillment of duty under Article 11, paragraph 5 of the Revised Penal Code requires not only that the accused acted in the performance of a duty but also that the injury inflicted was a necessary consequence of the due performance or lawful exercise of such duty. Without unlawful aggression from the victim, self-defense, whether complete or incomplete, cannot be appreciated.
