Eyewitness Testimony and Criminal Conviction: Credibility Rules in Philippine Courts

When a person is accused of a serious crime, the prosecution's case often rests on the testimony of an eyewitness. But how much weight do Philippine courts give to a single eyewitness, especially when the defense presents contradicting evidence? The Supreme Court's 2002 decision in People v. Jakosalem (G.R. No. 130506) provides clear guidance on this question, affirming that a credible lone eyewitness can be enough to convict, even against negative testimony from multiple defense witnesses.

The Facts of the Case

On December 10, 1988, in Maramag, Bukidnon, a 17-year-old boy named Arthur Tibayan was shot and killed. The sole eyewitness, Noe Tuban, testified that he saw two policemen—Rolando Jakosalem and Nelson Cayetona—boxing the victim. According to Tuban, Jakosalem then blindfolded Tibayan with a handkerchief and shot him in the chest. As the boy was about to fall, Cayetona also shot him. Jakosalem then threatened the onlookers that he would shoot them too.

The police investigation revealed that Tibayan was shot because he allegedly stole a bicycle. Jakosalem was charged with murder under Article 248 of the Revised Penal Code. The trial court convicted him, and he appealed to the Supreme Court.

The Issue: Credibility of the Sole Eyewitness

Jakosalem raised several arguments on appeal, but the central issue was the credibility of the prosecution's lone eyewitness. He pointed to alleged inconsistencies between Tuban's testimony and the physical evidence:

• The autopsy report supposedly placed the crime scene at a different location than where Tuban said it happened
• The forensic evidence suggested the gunshot came from the victim's back, not the front as Tuban testified
• Tuban said the victim wore long pants, but photographs showed him in short pants

The defense also presented several witnesses who claimed they heard and saw nothing unusual on the evening of the killing.

The Ruling: Minor Inconsistencies Do Not Destroy Credibility

The Supreme Court affirmed the conviction, holding that the inconsistencies pointed out by the defense were minor and did not detract from Tuban's positive identification of the accused. The Court emphasized a key principle: minor inconsistencies can actually enhance a witness's credibility because they remove any suspicion that the testimony was contrived or rehearsed.

The Court also applied the well-settled rule that affirmative testimony is stronger than negative testimony. When a credible witness positively testifies that an event occurred, that testimony carries more weight than several witnesses who merely say they did not see or hear anything. This is especially true when the defense fails to show any improper motive for the eyewitness to falsely testify.

Preliminary Investigation Is Not Part of the Trial

Jakosalem also argued that he should have been exonerated because his co-accused was discharged during the preliminary investigation, and because the records of that investigation were not presented as evidence in court.

The Court rejected this argument, explaining that a preliminary investigation is not a trial or any part of it. Its only purpose is to determine whether the accused should be held for trial. The records of a preliminary investigation do not automatically form part of the trial court records, and the prosecution is not required to offer them as evidence. Once an information is filed in court, the case is adjudicated by the trial judge based on the evidence presented during trial—not on what happened during the preliminary investigation.

Treachery and Penalty

The Court upheld the trial court's finding of treachery, which qualified the killing as murder. Treachery exists when the offender employs means that directly and specially ensure the execution of the crime without risk to himself. Here, the victim was blindfolded and unarmed, making him helpless and unable to defend himself.

The Court also noted that while the prosecution alleged abuse of superior strength, this was absorbed in treachery, so it did not need to be separately established. The penalty of reclusion perpetua was correctly imposed.

Practical Takeaways

• A single credible eyewitness can sustain a conviction in Philippine criminal cases, even if the defense presents multiple witnesses testifying in the negative.
• Minor inconsistencies in testimony do not automatically destroy credibility; they may even strengthen it by showing the testimony was not rehearsed.
• Positive testimony outweighs negative testimony. Courts give more weight to a witness who affirmatively saw an event than to witnesses who merely claim they did not see it.
• Preliminary investigation records are separate from trial records. What happens during a preliminary investigation does not bind or influence the trial court's determination of guilt.
• To recover actual damages, such as burial expenses, claimants must present receipts or other documentary evidence. Testimony alone about expenses is insufficient.
