Credible Witness Testimony Key to Conviction in Philippine Courts

The Supreme Court has long held that a single witness's credible testimony can be enough to convict a person of a crime. In People v. De Labajan (G.R. Nos. 129968-69, October 27, 1999), the Court reaffirmed this principle while also explaining why the defense of alibi often fails. This case offers valuable lessons on how Philippine courts weigh witness credibility and why positive identification typically prevails over alibi.

The Facts of the Case

On the evening of September 10, 1994, Romeo Miano, Jr. and Marites Carpio were inside a house in Silang, Cavite when gunshots rang out. Miano died instantly from a gunshot wound to the chest, while Carpio survived but was seriously wounded.

The prosecution's key witness was Evelyn Termo, the owner of the house. She testified that she saw the accused, Armando De Labajan, move a plastic curtain near the kitchen and fire a gun. She was only two to three meters away and the house was illuminated by a gas lamp. Termo positively identified De Labajan as the shooter.

The Defense of Alibi

De Labajan claimed he was elsewhere at the time of the shooting. He testified that he had spent the afternoon seeking financial assistance for his brother's medicine. His employer, Cosme Sierra, corroborated his story, saying De Labajan was still within sight when gunshots were heard.

The trial court found the defense's story suspicious. Notably, De Labajan's mother-in-law, who he claimed was with him throughout the day, was never presented as a witness. The court also found it odd that De Labajan went home to sleep instead of visiting his injured brother in the hospital.

The Supreme Court's Ruling

The Supreme Court affirmed the conviction, emphasizing two well-established doctrines:

First, the testimony of a single witness who positively identifies the accused, given in a straightforward and clear manner, is sufficient to sustain a finding of guilt. The Court noted that Termo had no motive to falsely testify against De Labajan, who was her compadre and neighbor.

Second, alibi cannot prevail over the positive testimonies of prosecution witnesses. For alibi to be credible, it must demonstrate physical impossibility—meaning the accused could not have been at the crime scene due to distance or lack of access. In this case, De Labajan was only about ten meters from the crime scene, making it entirely possible for him to have committed the crime.

Why Minor Inconsistencies Don't Destroy Credibility

The defense pointed to inconsistencies in Termo's testimony, particularly regarding when she saw the accused fire the gun. The Court dismissed these concerns, citing established jurisprudence that discrepancies in minor details actually indicate veracity rather than prevarication. Such minor inconsistencies tend to bolster, not weaken, a witness's credibility.

The Court also reminded that trial courts are in the best position to assess witness credibility because they observe witnesses firsthand—their demeanor, conduct, and attitude under examination. Appellate courts generally defer to these assessments.

Practical Takeaways

• Positive identification matters: A single credible witness who clearly identifies the accused can be enough for conviction, even without other evidence.
• Alibi is a weak defense: For alibi to succeed, it must show physical impossibility of being at the crime scene, not just that the accused was somewhere else.
• Credibility is key: Courts look at whether witnesses have motive to lie, whether their testimony is straightforward, and whether it is consistent on material points.
• Minor inconsistencies are normal: Small discrepancies in testimony do not automatically destroy credibility; they may even make the testimony more believable.
• Corroboration matters: Failing to present witnesses who could corroborate a defense story can seriously undermine its credibility.
