When Buy-Bust Operations Fail: Why Inconsistent Police Testimony Leads to Acquittal in Drug Cases

Supreme Court acquits drug suspect after police witnesses gave conflicting accounts of the buy-bust operation, underscoring the prosecution's burden of proof.


In a significant ruling on drug cases, the Supreme Court overturned the conviction of Alberto Gonzales y Vital for illegal sale and possession of shabu under Republic Act No. 9165. The Court's decision in People of the Philippines v. Alberto Gonzales y Vital (G.R. No. 233544, March 25, 2019) serves as a reminder that the prosecution's evidence must stand on its own weight, regardless of how weak the defense may be. When key police witnesses contradict each other on material points, the case against the accused collapses.

The Facts of the Case

On June 19, 2008, police officers in Mabalacat, Pampanga conducted a buy-bust operation against Gonzales, who was suspected of selling shabu. PO3 Dindo Dizon acted as the poseur-buyer, while PO2 Romeo Yambao served as back-up. The prosecution claimed that Gonzales sold 0.0896 grams of shabu to PO3 Dizon for P200.00, and that a second sachet containing 0.1110 grams was recovered from his possession upon arrest.

Gonzales denied the charges, claiming he was sleeping when police entered his house, searched his belongings, and later presented two plastic sachets and marked money as evidence against him. Both the Regional Trial Court and the Court of Appeals convicted him, giving credence to the police officers' testimonies.

The Issue Before the Supreme Court

The central question was whether the prosecution's evidence was sufficient to prove Gonzales' guilt beyond reasonable doubt for violating Sections 5 and 11 of R.A. No. 9165.

The Supreme Court's Ruling

The Supreme Court acquitted Gonzales, finding that the prosecution failed to establish its case. The Court emphasized that while trial courts' factual findings are generally given great weight, this rule does not apply where material facts have been overlooked or misappreciated.

Contradictory Testimonies of Key Witnesses

The Court found glaring inconsistencies between the testimonies of the two police officers. PO3 Dizon initially testified that PO2 Yambao apprehended Gonzales and confiscated the marked money and second sachet. However, in a later testimony, he claimed that he himself made the arrest, without explaining the sudden change.

PO2 Yambao's testimony contradicted PO3 Dizon's initial account entirely. Yambao testified that it was PO3 Dizon who arrested Gonzales, ordered him to empty his pockets, and recovered both the marked money and the second sachet.

The Court noted: "An inconsistency as glaring and as fundamental as the identity of the officer who caught Alberto and confiscated the second sachet of shabu and marked money casts serious doubt on the veracity of their testimonies."

Marking Irregularities

The Court also found it difficult to believe PO3 Dizon's claim that PO2 Yambao placed his initials "RY" on the second sachet. This contradicted the confiscation receipt prepared by PO3 Dizon himself, which indicated the marking "DSD-2"—signifying that PO3 Dizon confiscated it.

Weak Defense Does Not Strengthen Weak Prosecution

While the Court acknowledged that Gonzales' defense of denial and frame-up was uncorroborated and viewed with disfavor, it stressed that this did not help the prosecution's case. As the Court stated: "The evidence for the prosecution must stand or fall on its own weight and cannot be allowed to draw strength from the weakness of the defense."

Practical Takeaways

  • Consistent police testimony is crucial. Contradictions between arresting officers on who made the arrest or recovered evidence can destroy the prosecution's case, as these are material points that go to the heart of the buy-bust operation.
  • The prosecution carries the full burden of proof. Even when the accused's defense is weak or uncorroborated, the prosecution must still prove guilt beyond reasonable doubt through credible evidence.
  • Documentation must match testimony. When a confiscation receipt or other official document contradicts a witness's testimony, courts will question the credibility of the entire narration.
  • Courts are vigilant against abuse in drug operations. The Supreme Court acknowledged that buy-bust operations are susceptible to abuse, including the planting of evidence, and that the presumption of regularity cannot override the constitutional presumption of innocence.
  • Corpus delicti must be established through credible witnesses. The identity of the officer who recovered the drugs and money is fundamental to establishing the chain of custody and the integrity of the seized items.
