In People v. Dumayan, the Supreme Court affirmed the conviction of Paquito Dumayan for murder, emphasizing that in cases of conspiracy, the act of one is the act of all. This means that if individuals conspire to commit a crime, each participant is equally responsible, regardless of their specific role in the act. The court underscored the importance of establishing conspiracy through overt acts demonstrating a common design and purpose. This ruling reaffirms the principle that those who act together in the commission of a crime share equal criminal liability, promoting accountability for collective wrongdoing.

Shared Intent, Shared Guilt: How Conspiracy Determines Criminal Responsibility

The case revolves around the fatal stabbing of Carlito Tamayo on February 1, 1992, in Malolos, Bulacan. Paquito Dumayan, along with Eddie Dumayan, Allan Real, and Romy Loyola Bergardo, were accused of acting in concert to kill Tamayo. The prosecution presented evidence indicating that the group attacked Tamayo, resulting in multiple stab wounds that led to his death. Paquito Dumayan, however, claimed alibi, asserting that he was at work during the incident and could not have participated in the crime. The trial court convicted Paquito Dumayan of murder, leading to his appeal before the Supreme Court.

The Supreme Court meticulously examined the evidence presented, focusing on the credibility of eyewitness testimonies and the existence of a conspiracy among the accused. The Court noted that the testimonies of Anastacia Tamayo, the victim’s common-law wife, and Emilia Santos, a neighbor, were crucial in establishing the events of that day. Despite the appellant’s attempts to discredit their testimonies based on their relationship with the victim and alleged inconsistencies, the Court affirmed the trial court’s assessment of their credibility. The Court stated that:

It should be emphasized that where the credibility of witnesses is concerned, this Court does not generally disturb the appreciation of the trial court considering that the latter is in a better position to decide the question, having heard the witnesses themselves and observed their deportment and manner of testifying during the trial.

The Court highlighted that relationship per se does not automatically impair a witness’s credibility. The absence of improper motive to fabricate testimonies was crucial in upholding the eyewitness accounts. This principle is important because it prevents the dismissal of credible testimonies based solely on familial or personal connections to the victim.

The defense of alibi presented by Paquito Dumayan was deemed insufficient. The Court reiterated the principle that positive identification by credible witnesses outweighs the defense of denial and alibi. The Court emphasized that:

We have invariably held that positive identification, where categorical and consistent, prevails over denial and alibi which are negative and self-serving evidence undeserving of weight in law, if not substantiated by clear and convincing evidence.

The payroll sheet presented as evidence of his presence at work was considered inadmissible due to it being a mere xerox copy without the appellant’s signature. Additionally, the testimony of Norma Dumayan, the appellant’s niece, was not given credence as she did not witness the actual stabbing incident.

The Supreme Court also delved into the presence of conspiracy among the accused. The testimonies of the prosecution witnesses indicated that the appellant and his co-accused arrived together at the victim’s house, chased him after the initial attack, and simultaneously stabbed and hacked him. The Court explained that:

A conspiracy exists when two or more persons come to an agreement concerning the commission of a felony and decide to commit it.

The Court emphasized that direct proof of a prior agreement is not always necessary. Concerted actions demonstrating a common design are sufficient to establish conspiracy. In this case, the act of assisting one another in simultaneously attacking the victim clearly indicated a concerted effort to bring about his death. The Court affirmed that when conspiracy is proven, the act of one conspirator is the act of all, making each participant equally liable for the crime. This is a cornerstone of criminal law, ensuring that individuals who participate in a collective criminal endeavor are held accountable regardless of their specific role.

Furthermore, the Court affirmed the presence of treachery as a qualifying circumstance, noting that the sudden and unexpected attack on the unarmed victim who had no opportunity to defend himself constituted alevosia. Two conditions must concur to constitute treachery:

1) the employment of means of execution that gives the person attacked no opportunity to defend himself or to retaliate; and 2) deliberate or conscious adoption by the culprit of the means of execution.

Although the Information also alleged evident premeditation, the Court found that there was no sufficient proof to support its existence. For evident premeditation to be appreciated, it is essential to establish (1) the time when the offender determined to commit the crime, (2) an act manifestly indicating that the culprit clung to his determination, and (3) a sufficient lapse of time between the determination and the execution to allow him to reflect upon the consequences of his act.

The practical implications of this ruling are significant. It reinforces the principle of collective responsibility in criminal law, emphasizing that individuals who participate in a conspiracy are equally liable for the resulting crime. This serves as a deterrent to group crimes and promotes accountability among co-conspirators. It also highlights the importance of credible eyewitness testimonies in establishing the facts of a case and the limitations of defenses such as alibi when faced with positive identification. Finally, it reaffirms the concept of treachery as a qualifying circumstance that elevates the crime to murder, reflecting the heinous nature of attacks against unsuspecting victims.
