Broken Chains: How Mishandling Evidence Leads to Acquittal in Drug Cases

The Supreme Court has once again underscored that in drug cases, the prosecution must do more than prove possession—it must also prove that the seized drugs presented in court are the very same items taken from the accused. In People v. Pagal (G.R. No. 251894, March 2, 2022), the Court acquitted Johnny Pagal y Lavarias of illegal possession of dangerous drugs because the police committed serious lapses in handling the evidence. The ruling is a powerful reminder that procedural compliance is not mere formality; it is the foundation of a fair conviction.

The Facts of the Case

On October 14, 2016, an executive judge issued Search Warrant No. 33-2016-L against Pagal for keeping dangerous drugs in his residence in Lingayen, Pangasinan. Three days later, at around 5:00 a.m., police officers implemented the warrant. During the search, they found four plastic sachets of shabu inside a Marlboro cigarette pack on top of a television in the living room, as well as drug paraphernalia in a nephew's room.

The police marked the seized items in the presence of Pagal, a barangay kagawad, and a media representative who arrived only when the search was nearly finished. The items were later submitted to the crime laboratory, where they tested positive for methamphetamine hydrochloride, or shabu.

Pagal was charged with illegal possession of dangerous drugs under Section 11 of Republic Act No. 9165 and illegal possession of drug paraphernalia under Section 12. The trial court convicted him of illegal possession of dangerous drugs but acquitted him of the paraphernalia charge. The Court of Appeals affirmed the conviction, and Pagal appealed to the Supreme Court.

The Issue: Was Guilt Proven Beyond Reasonable Doubt?

The central question was whether the prosecution had established Pagal's guilt beyond reasonable doubt—specifically, whether the identity and integrity of the seized drugs had been preserved.

The Supreme Court ruled that it had not. Pagal was acquitted.

The Chain of Custody Rule Under Section 21

Under Section 21 of Republic Act No. 9165, the apprehending team must conduct a physical inventory and photograph the seized items immediately after seizure, in the presence of the accused or their representative, an elected public official, and a representative of the National Prosecution Service or the media. The inventory and photographing must be done at the place where the search warrant is served.

The Court explained that the presence of these witnesses is crucial to protect against the evils of planting, contamination, or loss of the seized drugs. When the prosecution fails to comply with these requirements, it must explain the deviations and prove that the integrity and evidentiary value of the seized items were preserved.

Four Fatal Lapses in the Chain of Custody

The Supreme Court identified several serious gaps in the prosecution's handling of the evidence:

First, the required witnesses were not present during the seizure. The media representative arrived only when the search was about to finish. The police had three days to prepare after the warrant was issued, so there was no excuse for starting the search without all witnesses present.

Second, the marking and inventory were done outside the house. The law requires these to be conducted at the place where the search warrant is served. The prosecution did not explain why this was not done, nor did it identify any safety measures taken to preserve the drugs' integrity.

Third, the investigating officer had no role in handling the drugs. Although a police officer was designated as the investigating officer, it was the seizing officer who delivered the drugs to the crime laboratory. This created a gap in the second and third links of the chain of custody.

Fourth, the fourth link was not established. There was no testimony on how the evidence custodian preserved the integrity of the drugs before they were presented in court. The Court of Appeals had relied on the Chain of Custody Form, but the Supreme Court held that written records cannot replace the required testimony of every person who handled the evidence.

Why Strict Compliance Matters

The Court emphasized that illegal drugs are not readily identifiable and are easily susceptible to tampering, alteration, or substitution. For this reason, the prosecution must prove beyond reasonable doubt that the items offered in court are the same items seized from the accused.

The Court also noted that the amount of shabu involved was only 0.1 gram. When only a minuscule amount of narcotics is involved, the requirements of Section 21 demand even more exacting compliance.

Practical Takeaways

• Chain of custody is the backbone of drug prosecutions. The prosecution must account for every link, from seizure and marking to turnover, laboratory examination, and presentation in court.
• Witnesses must be present at the time of seizure, not just inventory. Their presence protects against planting and contamination of evidence.
• Marking and inventory must be done at the place of seizure. Deviations must be justified with concrete explanations and proof of safety measures.
• Written forms cannot replace testimony. The prosecution must present the testimony of every person who handled the seized drugs.
• Small amounts of drugs require stricter compliance. The smaller the quantity, the more exacting the courts will be in scrutinizing the chain of custody.
