Shifting Sands of Evidence: Drug Sale Convictions and the Weight of Testimony

In every prosecution for illegal sale of drugs, the prosecution must prove the transaction and present the seized drugs in court. But what happens when the police officers themselves give conflicting accounts of the buy-bust operation? The Supreme Court’s 2002 decision in People v. Astudillo (G.R. No. 140088) offers a clear guide on how courts weigh such conflicting testimonies, and it also clarifies an important rule on aggravating circumstances that can mean the difference between life and death.

The Case: A Divisoria Buy-Bust

In May 1998, police received a tip that a certain “Babes” was looking for a buyer of shabu. A buy-bust team was formed, led by P/Insp. Jean Fajardo. On May 20, 1998, Fajardo met Phoebe Astudillo and Ku Sho Ping at a McDonald’s in Divisoria, Manila. After inspecting a gold plastic bag that Ku Sho Ping brought, Fajardo signaled her team and arrested both women. The bag contained nearly three kilograms of shabu.

The accused denied the charges. Astudillo claimed she was merely waiting for a taxi when she was grabbed by police. Ku Sho Ping said she was arrested while buying vegetables. More importantly, a defense witness—P/Insp. Efren Valmores, who was himself part of the buy-bust team—testified that the operation was not successful and that no sale took place.

The Issue: Whose Testimony to Believe

The central question was one of credibility. The trial court believed the prosecution’s version and convicted both women, imposing the death penalty. The Supreme Court affirmed the conviction but modified the penalty.

The Court reiterated the long-standing rule that it will not disturb the trial court’s assessment of witness credibility, since the trial judge has the unique opportunity to observe the witnesses’ demeanor. The Court found that Valmores’ testimony did not actually contradict the prosecution’s essential account. While Valmores claimed the operation failed, his testimony actually placed Ku Sho Ping at the McDonald’s—undermining her alibi that she was buying vegetables elsewhere.

More decisive was the testimony of PO1 Jose Pedroza, who was seated just four meters away and gave a detailed, categorical account of the entire transaction: the meeting, the showing of the boodle money, Ku Sho Ping’s departure and return with the bag, and the consummation of the sale. Between Valmores’ uncertain account and Pedroza’s clear testimony, the Court chose the latter.

The Rules on Evidence in Drug Cases

The Court reaffirmed two important principles. First, in prosecutions for illegal sale of drugs, the absence of marked money does not create a gap in the prosecution’s evidence, as long as the sale is adequately proven and the drug itself is presented in court. The law does not require the presentation of the buy-bust money.

Second, the defenses of denial and frame-up are viewed with disfavor, as they are easily concocted and are common in drug prosecutions.

The Penalty: Why the Death Sentence Was Reduced

Although the Court affirmed the conviction, it corrected the penalty. The trial court had imposed death, citing the aggravating circumstance that the offense was committed by an organized or syndicated crime group. The Supreme Court disagreed on two grounds.

First, there was no proof that the accused belonged to a group organized for the general purpose of committing crimes for gain. Merely confederating for a single transaction does not make a syndicate.

Second, and more significantly, the aggravating circumstance was not alleged in the information. Under Rule 110, Section 8 of the Revised Rules of Criminal Procedure, qualifying and aggravating circumstances must be alleged in the complaint or information; otherwise, they cannot be considered even if proven. Since this procedural rule is favorable to the accused, it was given retroactive effect. The penalty was therefore reduced to reclusion perpetua, and the fine was increased to P500,000.00 in line with recent jurisprudence.

Practical Takeaways

• Credibility is key. Courts give great weight to the trial court’s assessment of witnesses, especially when the prosecution witness was in a position to observe the entire transaction clearly.
• Conflicting police testimony is not fatal. A defense witness’s account that contradicts the prosecution’s version does not automatically create reasonable doubt, especially if it is uncertain or internally inconsistent.
• Marked money is not required. In drug sale cases, the prosecution need only prove the transaction and present the seized drugs in court.
• Allegations matter. Aggravating circumstances must be stated in the information. If not alleged, they cannot be used to increase the penalty—even if proven at trial.
• Denial and frame-up are weak defenses. These are common and easily fabricated, so they rarely prevail against credible prosecution evidence.
