In People v. Court of Appeals and Tangan, the Supreme Court clarified the application of self-defense in homicide cases, emphasizing the critical role of unlawful aggression. The Court ruled that to successfully claim self-defense, the accused must first demonstrate that the victim committed unlawful aggression. Absent such aggression, a claim of self-defense, whether complete or incomplete, cannot stand. This ruling highlights the importance of establishing who initiated the unlawful act, as this determines the viability of a self-defense argument.

Roxas Boulevard Rumble: Did Tangan Act in Self-Defense?

The case arose from an altercation on Roxas Boulevard involving Navy Captain Eladio Tangan and Generoso Miranda. After a road incident where firecrackers thrown in front of Miranda’s car caused him to swerve into Tangan’s lane, a heated exchange ensued. The confrontation escalated when both men exited their vehicles, leading to a struggle over Tangan’s firearm and the fatal shooting of Miranda. Tangan was initially charged with murder but was later convicted of homicide in the lower courts, with the mitigating circumstance of incomplete self-defense factored into his sentence.

The prosecution and defense presented conflicting accounts of the shooting. The prosecution argued that Tangan intentionally shot Miranda at close range. Tangan, on the other hand, claimed the gun discharged accidentally during a scuffle with Miranda and his uncle. The trial court appreciated the privileged mitigating circumstance of incomplete self-defense, alongside sufficient provocation and passion/obfuscation, resulting in a lighter sentence. The Court of Appeals affirmed the conviction but increased the civil indemnity.

The Supreme Court addressed two key issues: first, the propriety of the Solicitor General’s petition questioning the lower court’s appreciation of mitigating circumstances; and second, the validity of Tangan’s claim of incomplete self-defense. The Court first addressed the Solicitor General’s petition, dismissing it on the grounds of double jeopardy. It cited jurisprudence that prohibits the prosecution from seeking remedies like certiorari to correct factual findings or evaluations of evidence in criminal cases. Allowing such petitions would violate the accused’s constitutional right against being tried twice for the same offense.

Turning to Tangan’s petition, the Court delved into the elements of self-defense. Central to this analysis is the concept of unlawful aggression, a condition precedent for any self-defense claim. According to the Revised Penal Code, self-defense requires (1) unlawful aggression; (2) reasonable necessity of the means employed to prevent or repel it; and (3) lack of sufficient provocation on the part of the person defending himself.

ARTICLE 11. Justifying circumstances. – The following do not incur any criminal liability:

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.

The Court emphasized that unlawful aggression must originate from the victim, not the accused. A mere threatening attitude or exchange of insults does not constitute unlawful aggression unless coupled with physical assault. Since Tangan initiated the blocking of Miranda’s vehicle and the confrontation escalated from there, it was determined there was no unlawful aggression on the part of Miranda. The absence of this key element invalidated Tangan’s claim of incomplete self-defense.

The Court also rejected the mitigating circumstances of sufficient provocation and passion/obfuscation. It reasoned that Tangan’s act of repeatedly blocking Miranda’s path constituted the initial provocation. Furthermore, the Court found no basis for passion or obfuscation, as there was no sudden or unexpected occurrence that would have caused Tangan to lose control. Ultimately, the Supreme Court modified the penalty imposed on Tangan, sentencing him to an indeterminate penalty of six years and one day of prision mayor, as minimum, to fourteen years, eight months and one day of reclusion temporal, as maximum.
