When Group Action Erases Self-Defense: Understanding Conspiracy in Criminal Law

G.R. No. 92153, December 16, 1996

Imagine witnessing a brutal attack, unsure who struck the fatal blow. Can everyone involved be held equally responsible? This case clarifies the complexities of criminal liability when multiple individuals participate in a crime, particularly when one claims self-defense. It underscores that when individuals act together with a common purpose, the actions of one become the actions of all, nullifying individual claims of self-defense.

Introduction

In the Philippines, the concept of conspiracy plays a significant role in determining criminal liability, especially in cases involving multiple accused. This legal principle blurs the lines of individual culpability, holding all participants accountable for the collective actions of the group. The case of *People of the Philippines vs. Artemio Obzunar, et al.* delves into this complex area, illustrating how the actions of a group can negate a claim of self-defense by one of its members. The central question is: can an individual claim self-defense when acting as part of a group engaged in an unlawful attack?

The case revolves around the death of Anastacio Macato, who was fatally stabbed and assaulted by a group of seven individuals. One of the accused, Virgilio Obzunar, admitted to inflicting the fatal stab wound but claimed he acted in self-defense. However, the prosecution argued that the accused acted in conspiracy, making each of them equally responsible for the murder, regardless of who delivered the final blow. The Supreme Court was tasked with determining whether conspiracy existed and whether Virgilio Obzunar’s claim of self-defense could stand in light of the collective actions of the group.

Legal Context: Conspiracy and Self-Defense in Philippine Law

Philippine criminal law recognizes conspiracy as a circumstance where two or more persons come to an agreement concerning the commission of a felony and decide to commit it. Article 8 of the Revised Penal Code defines conspiracy as existing “when two or more persons come to an agreement concerning the commission of a felony and decide to commit it.”

The effect of proving conspiracy is that the act of one conspirator becomes the act of all. This means that each member of the conspiracy is held equally liable for the crime committed, regardless of their individual participation. Conspiracy need not be proven by direct evidence; it can be inferred from the conduct of the accused before, during, and after the commission of the crime, demonstrating a common purpose or design. For example, if a group plans to rob a bank and one member shoots a security guard, all members of the group can be charged with murder, even if they didn’t pull the trigger.

Self-defense, on the other hand, is a justifying circumstance that exempts an individual from criminal liability. Article 11 of the Revised Penal Code outlines the elements of self-defense: unlawful aggression, reasonable necessity of the means employed to prevent or repel it, and lack of sufficient provocation on the part of the person defending himself. The most critical element is unlawful aggression. This means there must be an actual, imminent, and unlawful attack that puts the person’s life in danger. For instance, if someone attacks you with a knife, and you use reasonable force to defend yourself, you may be able to claim self-defense.

Case Breakdown: The Obzunar Murder Case

The story begins on the evening of May 6, 1988, in Talalora, Samar. Lydia Zilmar, while at home, heard a woman’s cry for help. Peeking through her window, she witnessed a group of men chasing her brother, Anastacio Macato. She identified the pursuers as Artemio Obzunar, Virgilio Obzunar, Nelson Isanan, Alfredo Isanan, Sr., Alfredo Isanan, Jr., Jose Superio, and Julio Zilmar – the accused-appellants in this case. According to Lydia, Artemio Obzunar overtook Anastacio and stabbed him in the back. The other accused then joined in, kicking, boxing, and striking Anastacio with a piece of wood until he fell unconscious.

The prosecution presented additional evidence suggesting a motive for the killing. Maria Gina Figueroa, a COA employee, testified that Anastacio had assisted her audit team in investigating an infrastructure project, which angered the accused. The trial court found this testimony credible, establishing a motive for the accused to harm Anastacio.

The defense presented a different version of events. Virgilio Obzunar admitted to stabbing Anastacio but claimed he did so in self-defense. He testified that Anastacio had attacked him earlier that evening, smashing a bottle of tuba on his head. Later, Anastacio allegedly accosted him again and tried to strangle him, forcing Virgilio to defend himself with a knife.

The trial court, however, rejected Virgilio’s claim of self-defense and found all seven accused guilty of murder, based on conspiracy. The court sentenced them to *reclusion perpetua*, ordering them to jointly and severally pay damages to Anastacio Macato’s heirs.

Key points in the Supreme Court’s decision:

• “x x x when the question is raised as to whether to believe the version of the prosecution or that of the defense, the trial court’s choice is generally viewed as correct and entitled to the highest respect because it is more competent to conclude so, having had the opportunity to observe the witnesses’ demeanor and deportment on the witness stand, and the manner in which they gave their testimonies, and therefore could better discern if such witnesses were telling the truth; the trial court is thus in the best position to weigh conflicting testimonies.”
• “conspiracy need not be proved by direct evidence of prior agreement on the commission of the crime as the same can be inferred from the conduct of the accused before, during, and after the commission of the crime, showing that they acted in unison with each other, evincing a common purpose or design.”
• “absent any particulars as to the manner in which the aggression commenced or how the act which resulted in the death of the victim unfolded, as in this case, treachery cannot be appreciated.”

The Supreme Court affirmed the trial court’s decision, finding that the accused acted in conspiracy, negating Virgilio’s claim of self-defense. The court emphasized that the actions of the group demonstrated a common purpose to harm Anastacio, making each member equally liable for the crime.

Practical Implications: Lessons for Individuals and Groups

This case has significant implications for understanding criminal liability in group settings. It highlights the dangers of participating in any activity that could be construed as a conspiracy to commit a crime, even if one’s individual involvement seems minor. The ruling underscores the importance of disassociating oneself from any group activity that appears to be unlawful or dangerous.

Here are some key lessons from the *Obzunar* case:

• Conspiracy blurs the lines of individual liability: If you are part of a group that commits a crime, you can be held responsible for the actions of the entire group, even if you didn’t directly participate in the most serious aspects of the crime.
• Self-defense is difficult to claim in a conspiracy: If you are part of a group engaged in unlawful aggression, it will be difficult to claim self-defense, as your actions are seen as part of the group’s overall criminal intent.
• Disassociate yourself from suspicious activities: If you suspect that a group you are with is planning to commit a crime, remove yourself from the situation immediately to avoid being implicated.

Hypothetical: Imagine you are with a group of friends who decide to vandalize a building. You don’t participate in the actual vandalism, but you stay with the group. If someone gets injured during the act, you could be charged as a conspirator and held liable for the injuries, even though you didn’t directly cause them.
