When Can an Adverse Party Be Called as a Witness?

In Philippine courts, parties to a case sometimes wonder whether they can compel the opposing side to testify. The Supreme Court's decision in Guevarra v. People (G.R. No. 170462, February 5, 2014) provides a clear illustration of when an adverse party may be called to the witness stand — and how that testimony can shape the outcome of a criminal case.

The Case at a Glance

Rodolfo Guevarra and his son Joey were charged with frustrated homicide and homicide after a violent incident on November 8, 2000, in Alicia, Isabela. The prosecution alleged that the father-and-son team hacked and stabbed brothers Erwin and David Ordoñez, resulting in David's death and serious injuries to Erwin.

The petitioners claimed self-defense, asserting that the victims had forced their way into their compound, thrown stones at their house, and attacked them first. To counter this, the prosecution presented Erwin Ordoñez — the surviving victim — as its sole rebuttal witness.

The Prosecution's Use of an Adverse Party as Witness

A key procedural point in this case is that the prosecution called Erwin, who was the private complainant and thus an adverse party to the accused, to testify. This is permitted under the Rules of Court, which allow a party to call an adverse party as a witness and examine them as if on cross-examination.

Erwin testified that he and his brother were merely passing by the petitioners' compound when they were suddenly attacked. He denied throwing stones or damaging property, and described how he was hacked and stabbed thirteen times before losing consciousness.

The Court's Ruling on Self-Defense

The Supreme Court denied the petition and affirmed the convictions. The Court emphasized that when an accused invokes self-defense, they effectively admit to committing the act but claim justification. This admission shifts the burden of proof to the accused to establish the elements of self-defense:

1. Unlawful aggression on the part of the victim;
2. Reasonable necessity of the means employed to prevent or repel such aggression; and
3. Lack of sufficient provocation on the part of the person resorting to self-defense.

The Court stressed that unlawful aggression is the most critical element. It must consist of an actual physical assault or a real threat of imminent injury. Without unlawful aggression, there can be no self-defense — whether complete or incomplete.

Why the Defense Failed

The Court found that the petitioners failed to prove unlawful aggression. The prosecution's evidence, including Erwin's testimony, showed that the victims were attacked while merely passing by. The nature and number of wounds — ten on David and thirteen on Erwin — indicated a determined homicidal aggression rather than a defensive response.

The Court also noted that the manner in which the gate was destroyed supported the prosecution's version: David had clung to the gate while being dragged into the compound, which explained the damage. This contradicted the defense's claim that the victims had forcibly broken in.

Practical Takeaways

• An adverse party can be called to testify. The Rules of Court permit a party to call the opposing party as a witness, and such testimony can be powerful evidence.
• Self-defense requires proof of unlawful aggression. Mere threatening words or gestures are not enough; there must be an actual assault or a real, imminent threat of bodily harm.
• The burden shifts when self-defense is claimed. Once an accused invokes self-defense, they must prove all its elements with clear and convincing evidence.
• The number and nature of wounds matter. Courts often infer intent to kill and the absence of self-defense from the extent of injuries inflicted on the victim.
• Factual findings affirmed by the Court of Appeals are highly persuasive. The Supreme Court generally respects these findings unless there is a clear showing of overlooked evidence.
