When One Is Liable for All: Conspiracy in Gang Rape Under Philippine Law

The Supreme Court, in People v. Diega (G.R. No. 255389, September 14, 2021), reaffirmed a crucial principle in Philippine criminal law: when several persons conspire to commit a crime, the act of one is the act of all. This means an accused may be held criminally liable not only for the crime he personally committed, but also for the crimes perpetrated by his co-conspirators—even if those co-conspirators were never identified or remain at large.

The ruling provides important guidance on how conspiracy is established in rape cases and how damages are computed when multiple counts of rape are proven.

The Facts of the Case

In April 2013, a 12-year-old girl (referred to as "AAA" to protect her identity) was walking home with a friend when a man named Ismael blocked their path. Ismael brought AAA to a nearby store and introduced her to his friends, including Carlo Diega. The group forced AAA to join a drinking session at a riverbank and later at a vacant lot.

AAA became dizzy and drowsy from the liquor. She laid down and saw Carlo remove her pants and underwear. Despite her resistance—kicking and shouting—someone held her legs apart while another held her hands. Carlo went on top of her and inserted his penis into her vagina. Afterwards, Kalbo, Ismael, and Obat took turns raping her. AAA was left at the vacant lot, where she fell asleep and woke up at dawn to walk home.

The Issue Before the Court

The central question was whether Carlo Diega could be held liable for four counts of rape—including the rapes committed by his companions—or only for the single rape he personally committed. Carlo argued that his conviction should be reversed because AAA's testimony was allegedly incredible and because he had already gone home before the drinking spree ended.

The Ruling: Conspiracy Makes Each Liable for All

The Supreme Court dismissed Carlo's appeal and affirmed his conviction—but with a significant modification. The Court ruled that Carlo was guilty of four counts of Simple Rape, not just one, and sentenced him to reclusion perpetua for each count.

The Court explained that conspiracy may be deduced from the mode and manner in which the offense was perpetrated. Here, the evidence showed that Carlo and his three companions successively raped AAA, and while one had carnal knowledge of the victim, the others held her arms and legs to prevent her from struggling. Viewed in its totality, their individual participation pointed to a joint purpose and criminal design.

Citing prior cases (People v. Plurad, People v. Catubig, Jr., People v. Sabal, and People v. Rondina), the Court held that an accused is responsible not only for the rape he personally committed but also for the other counts of rape that his co-conspirators perpetrated, even if they were unidentified or at large. The rule is simple: where there is conspiracy, the act of one conspirator is the act of all.

Key Points on Evidence and Damages

The Court also clarified several evidentiary matters:

• Credibility of witnesses. The trial court's assessment of witness credibility is given the highest degree of respect, especially when no material fact or circumstance was overlooked. The trial court had the best opportunity to observe the witness's demeanor.

• Force need not be irresistible. Under Article 266-A of the Revised Penal Code, force need only be enough to bring about the desired result. A victim need not resist unto death; any physical overt act of resistance in any degree is sufficient.

• Denial and alibi. These negative defenses are self-serving and cannot prevail over the positive identification of the accused, especially when it was not physically impossible for him to be at the crime scene.

• Damages. For each count of rape, the Court awarded P75,000.00 as civil indemnity, P75,000.00 as moral damages, and P75,000.00 as exemplary damages, all with legal interest at 6% per annum from finality of judgment until full payment. The accused was made solidarily liable with his co-conspirators for the damages—meaning each may be compelled to pay the entire obligation.

Practical Takeaways

• Conspiracy can be inferred from conduct. There is no need for a written agreement. Joint action and a common purpose, shown by how the crime was committed, are enough to establish conspiracy.

• Unidentified co-offenders do not reduce liability. An accused cannot escape liability for the acts of co-conspirators simply because those co-conspirators were never caught or identified.

• Conviction is per count, not per person. When multiple rapes are committed in succession by different persons acting in conspiracy, each conspirator is guilty of each count of rape—not just the one he personally committed.

• Solidary liability for damages. Victims can recover the full amount of damages from any one of the co-conspirators, who may then seek contribution from the others.
