In the case of People of the Philippines vs. Dennis Mazo, the Supreme Court clarified the application of self-defense, treachery, and voluntary surrender in a homicide case. The Court modified the lower court’s decision, finding Mazo guilty of homicide instead of murder, as treachery was not proven. This ruling emphasizes the importance of proving each element of a crime beyond reasonable doubt and highlights how mitigating circumstances can alter the final conviction and sentence. It serves as a reminder of the nuances involved in criminal law and the critical role of evidence and witness credibility in determining guilt and punishment.

From Bar Brawl to Deadly Encounter: Was it Murder or Self-Defense?

The case revolves around an altercation that occurred in Romblon between Dennis Mazo and Rafael Morada, Jr., which ultimately led to Morada’s death. Mazo was initially charged with murder, with the prosecution arguing that he had intentionally killed Morada with treachery. The defense, however, claimed that Mazo acted in self-defense, asserting that Morada was the initial aggressor. This claim forced the court to evaluate the credibility of witnesses, the sequence of events, and the presence or absence of circumstances that could either justify or mitigate Mazo’s actions.

The prosecution presented Rommel Abrenica, who testified that Mazo initiated the assault by stabbing Morada. Dr. Victorio F. Benedicto, the Municipal Health Officer, provided medical evidence detailing the multiple stab wounds inflicted on the victim. The defense, on the other hand, presented Mazo, who claimed that Morada attacked him first with a knife, and he acted only to defend himself. Mazo’s account was supported by his companions, Gerry Moreno and Anthony Mortel, who corroborated his version of the events.

The trial court convicted Mazo of murder, swayed by the prosecution’s evidence and finding the presence of treachery. However, the Supreme Court took a different view, carefully dissecting the evidence and arguments presented by both sides. The Court critically assessed the credibility of Rommel Abrenica, whose testimony was central to the prosecution’s case. While the defense attempted to discredit Abrenica by pointing out his alcohol consumption on the night of the incident, the Court found that his testimony remained credible and consistent.

The Court also considered the testimony of Adrian Yap, a rebuttal witness for the prosecution, who testified that he saw Mazo chasing Morada. The defense challenged Yap’s testimony, questioning why he was not presented during the initial presentation of evidence and arguing that his account was uncorroborated. However, the Court noted that the defense had failed to object to Yap’s testimony and found his account to be detailed and spontaneous, thus worthy of belief. In addressing the issue of self-defense, the Supreme Court reiterated that when an accused admits to killing the victim but claims self-defense, the burden of proof shifts to the accused to demonstrate the elements of self-defense clearly and convincingly.

The Revised Penal Code outlines the elements of self-defense in Article 11, which states:

1. Anyone who acts in defense of his person or rights, provided that the following circumstances concur:
First. Unlawful aggression;
Second. Reasonable necessity of the means employed to prevent or repel it;
Third. Lack of sufficient provocation on the part of the person defending himself.

In this case, the Court found that Mazo failed to prove unlawful aggression on the part of Morada. The Court emphasized that unlawful aggression is an indispensable requisite for self-defense. Since Mazo’s claim of self-defense hinged on the assertion that Morada was the initial aggressor, the failure to prove this element proved fatal to his defense.

The Court, however, disagreed with the trial court’s finding of treachery. Treachery, as defined in Article 14 of the Revised Penal Code, involves employing means to ensure the execution of a crime against a person without risk to the offender from the defense the offended party might make. The Supreme Court stated that in this case, the encounter between Mazo and Morada was preceded by an altercation and an exchange of words, which put the victim on guard. Thus, the attack could not be considered treacherous. Moreover, the Court noted that the meeting between Mazo and Morada was by chance, and there was no evidence to suggest that Mazo had planned the attack.

The Supreme Court discussed how treachery requires a conscious decision and planning by the offender, stating:

In treachery, the mode of attack must be consciously adopted. This means that the accused must make some preparation to kill the deceased in such a manner as to insure the execution of the crime or to make it impossible or hard for the person attacked to defend himself or retaliate. The mode of attack, therefore, must be planned by the offender, and must not spring from the unexpected turn of events.

Since treachery was not proven, the Court concluded that Mazo could only be convicted of homicide, which does not require the presence of such qualifying circumstances. With the crime reclassified to Homicide, the circumstances surrounding Mazo’s surrender became important for sentencing. The final issue addressed by the Supreme Court was whether Mazo was entitled to the mitigating circumstance of voluntary surrender. The Revised Penal Code provides that voluntary surrender can reduce the penalty imposed on the offender, and to determine this, the Supreme Court considered the circumstances of his surrender to Senior Police Inspector Harry B. Mazo.

The requisites for voluntary surrender as a mitigating circumstance are: (1) the offender had not been actually arrested; (2) the offender surrendered himself to a person in authority; and (3) the surrender was voluntary. The Court found that Mazo had indeed voluntarily surrendered, as he had not been arrested and submitted himself to a person in authority with the intent to submit unconditionally. As such, the Supreme Court appreciated the mitigating circumstance of voluntary surrender in Mazo’s favor, which led to a reduced penalty. Voluntary surrender suggests an acknowledgment of guilt or an intention to save the authorities the trouble and expense that his search and capture would require. Mazo’s actions met these criteria, further justifying the modification of the sentence.

The Court considered the Indeterminate Sentence Law, which states that the court shall sentence the accused to an indeterminate sentence, the maximum term of which shall be that which, in view of the attending circumstances, could be imposed under the rules of the said Code, and the minimum of which shall be within the range of the period next lower to that prescribed by the Code for the offense. Considering the presence of one mitigating circumstance, the Court sentenced Mazo to imprisonment for a minimum term of eight (8) years and one (1) day of prision mayor to a maximum term of fourteen (14) years of reclusion temporal in its minimum period.
