Self-Defense vs. Treachery in Criminal Cases: The Conviction of PFC Enrique Reyes

Self-defense is a critical legal justification in violent crimes, but courts require clear proof of unlawful aggression for it to be valid. The Supreme Court case of People of the Philippines vs. PFC Enrique Reyes illustrates why self-defense claims must be backed by evidence and how treachery can escalate homicide to murder.

Background of the Case

PFC Enrique Reyes was charged with murder for the killing of Danilo Estrella on August 13, 1990.

  • Reyes fired his rifle upwards, then shot Danilo from behind, causing him to fall to the ground.

  • He then took Danilo’s gun and fired it upwards three times before placing it back in Danilo’s hand—suggesting an attempt to stage self-defense.

  • Reyes voluntarily surrendered, but claimed he acted in self-defense, citing a perceived looming threat from Danilo’s group.

The Regional Trial Court (RTC) convicted Reyes of murder, citing treachery, but the Court of Appeals (CA) downgraded it to homicide, ruling that aggravating circumstances were absent. The Supreme Court later reinstated the murder conviction due to clear evidence of treachery.

Key Legal Doctrines from the Case

1️⃣ Self-Defense Requires Actual Unlawful Aggression

  • Threats or assumptions of danger do not meet the legal threshold for self-defense.

  • The SC emphasized: > “To constitute imminent unlawful aggression, the attack must be at the point of happening and must not be imaginary or consist in a mere threatening attitude.”

  • Reyes’ claim of overhearing a murder plot did not amount to immediate danger, invalidating his self-defense argument.

2️⃣ Treachery Qualifies the Killing as Murder

  • Treachery occurs when a person ensures an attack is executed without risk to themselves.

  • In this case, Reyes fired multiple successive shots, preventing Danilo from escaping or defending himself, reinforcing the presence of treachery.

3️⃣ Excessive Force and Manipulation of Evidence Suggest Criminal Intent

  • Reyes altered the crime scene by firing Danilo’s weapon post-mortem, likely to make it appear like a shootout.

  • The multiple gunshot wounds indicated intent to kill, not just to defend.

Legal Takeaways from the Case

✅ Unlawful aggression must be immediate – Fear of potential danger does not justify self-defense.

✅ Treachery escalates homicide to murder – Courts consider whether the victim had a chance to defend themselves.

✅ Staging evidence undermines credibility – Any manipulation of crime scenes weakens the accused’s defense.

✅ Voluntary surrender does not erase guilt – While Reyes surrendered, it only mitigated penalties but did not absolve him of murder.

Conclusion

The Supreme Court’s ruling underscores the strict standards required for self-defense claims. Without clear, immediate, and actual aggression, defendants cannot justify their actions. Additionally, treachery remains a decisive factor in murder cases, ensuring justice is upheld.

G.R. No. 202124. April 5, 2016. PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. IRENEO JUGUETA, accused-appellant. PONENTE:  PERALTA, J.:  Synopsis: In Criminal Case No. 7702-G, Irenneo Jugueta was charged with Multiple Attempted Murder along with Gilbert Estores and Roger San Miguel.

No. 176422 | March 20, 2013 Ponente: 📌 Topic: Applicability of Reserva Troncal – First cousins of the descendant/prepositus are fourth-degree relatives and cannot be considered reservees/reservatarios.
