Self-Defense and the Burden of Proof: Establishing Unlawful Aggression in Philippine Law

,

In Oscar Santos v. Court of Appeals, the Supreme Court affirmed the conviction of Oscar Santos for two counts of frustrated homicide, emphasizing the stringent requirements for proving self-defense. The Court ruled that Santos failed to convincingly demonstrate unlawful aggression from the victims, a critical element for a successful self-defense claim. This case underscores the importance of clear and convincing evidence when asserting self-defense, especially regarding the imminence of threat and the reasonableness of the response. It clarifies that a mere threatening attitude does not constitute unlawful aggression.

Bolo, Toy Gun, or Real Threat: Did Santos Act in Self-Defense?

The case revolves around an incident on May 15, 1990, in Paombong, Bulacan. Oscar Santos was charged with two counts of frustrated homicide for attacking Loreto Hernandez and Roy de Borja with a jungle bolo. Santos claimed he acted in self-defense after Hernandez allegedly aimed a gun at him, which later turned out to be a toy. The trial court and Court of Appeals found Santos guilty, discrediting his self-defense plea. Santos appealed to the Supreme Court, arguing that the lower courts erred in assessing the credibility of witnesses and disregarding evidence supporting his claim of self-defense.

At the heart of self-defense is the concept of unlawful aggression. This legal requirement necessitates an actual, sudden, and unexpected attack or imminent threat to one’s life or limb, rather than merely a threatening demeanor. Building on this principle, the Court emphasized that without unlawful aggression from the victim, a claim of self-defense, whether complete or incomplete, cannot stand. Moreover, when an accused admits to inflicting injuries, the burden shifts to them to convincingly demonstrate that their actions were justified under self-defense. This contrasts sharply with the prosecution’s primary duty to prove guilt beyond a reasonable doubt. However, if the accused admits to the crime but claims self-defense, they must prove their case.

The Supreme Court found the evidence presented by Santos to be implausible and inconsistent. Foremost, Santos’s testimony was contradicted by medical evidence, specifically the location of Hernandez’s wounds. Secondly, the court deemed it improbable that Hernandez would threaten Santos, who was armed with a lethal bolo, with a mere toy gun. The act of disposing of the bolo further weakened Santos’s claim, as it is inconsistent with someone who acted purely in self-defense. Finally, Santos initially claimed ignorance of injuring De Borja, which contradicted his argument that he acted defensively against all aggressors. Therefore, the testimonies of Hernandez and De Borja that they were simply walking on a narrow pathway when they were suddenly attacked were found credible by the lower courts. This case hinges on the credibility of testimonial evidence and the consistency of actions with claims.

The Supreme Court also addressed the proper penalties for frustrated homicide, as well as the civil liabilities of the petitioner. The trial court incorrectly imposed penalties; the Supreme Court modified the indeterminate penalty for each count to range from two (2) years and four (4) months of prision correccional, as minimum, to six (6) years and one (1) day of prision mayor, as maximum, in accordance with the Revised Penal Code. Regarding civil liabilities, the Court adjusted the awards. It found that the actual damages claimed by De Borja and Hernandez were not adequately supported by documentary evidence. In such cases, the Court may award temperate damages when actual damages cannot be precisely determined but the right to damages is evident. Temperate damages and moral damages were awarded to the victims. Therefore, documenting all expenses related to medical treatment or lost wages becomes a critical step in substantiating claims for compensation. This adjustment highlights the judiciary’s role in ensuring proportionate justice and equitable compensation in criminal cases involving frustrated offenses.
