Safeguarding Rights: The Critical Role of Witness Presence in Drug Cases

The Supreme Court, in People v. Barrion y Silva (G.R. No. 240541, January 21, 2019), acquitted an accused charged with illegal sale of drugs because the police failed to justify the absence of a media representative during the inventory of the seized item. The ruling is a clear reminder that in drug cases, the prosecution must strictly account for every link in the chain of custody — and that procedural lapses, left unexplained, can cost the State a conviction.

The Facts of the Case

On the evening of August 10, 2011, police officers conducted a buy-bust operation against Rey Barrion in Lipa City, Batangas. A plastic sachet containing white crystalline substance was recovered from him. The arresting officer marked the item at the place of arrest and later brought it to the police station, where it was placed in a bigger plastic sachet and marked again.

The inventory and photography of the seized item were conducted in the presence of a Department of Justice (DOJ) representative and a barangay councilor. However, no media representative was present. The seized item tested positive for 0.04 gram of methamphetamine hydrochloride, or shabu.

Barrion denied the charges, claiming he was already detained at the time of the alleged arrest. The Regional Trial Court convicted him of illegal sale of dangerous drugs under Section 5, Article II of Republic Act No. 9165, and the Court of Appeals affirmed. On appeal, the Supreme Court reversed the conviction.

The Issue

The core question was whether the prosecution had sufficiently established the identity and integrity of the seized drugs — the corpus delicti — despite the absence of a media representative during the inventory.

The Chain of Custody Rule

In drug cases, the dangerous drug itself is the very object of the crime. The prosecution must therefore prove its identity with moral certainty by accounting for each link of the chain of custody — from seizure to presentation in court.

Under Section 21, Article II of RA 9165, as amended by RA 10640, the marking, physical inventory, and photography of seized items must be conducted in the presence of the accused or his representative, and certain required witnesses: an elected public official and a representative of the National Prosecution Service or the media. These witnesses are required to ensure the chain of custody is established and to remove any suspicion of switching, planting, or contamination of evidence.

The Saving Clause and Its Limits

The Court recognized that strict compliance may not always be possible due to field conditions. However, for the saving clause to apply, the prosecution must prove two things: (1) a justifiable ground for non-compliance, and (2) that the integrity and evidentiary value of the seized items were preserved.

Crucially, the justifiable ground must be proven as a fact — the Court cannot presume what these grounds are or that they even exist. Mere statements of unavailability, absent actual serious attempts to contact the required witnesses, are not acceptable.

Why the Conviction Was Reversed

In this case, the inventory sheet showed only the DOJ representative and the barangay councilor were present. The team leader testified that the police "called" the media but no representative arrived. The Court found this insufficient.

The police offered no reasonable justification for the absence of a media representative, and they failed to show that they exerted genuine and sufficient efforts to secure one. Because the deviation was unjustified, the Court concluded that the integrity and evidentiary value of the seized item were compromised — warranting acquittal.

The Court reiterated that the chain of custody rule is not a mere procedural technicality but a matter of substantive law, crafted to address potential police abuses, especially where the penalty can be life imprisonment.

Practical Takeaways

• Witness presence is mandatory. In drug seizures, the required witnesses — an elected public official and a representative of the National Prosecution Service or the media — must be present during inventory and photography.
• Unjustified lapses can lead to acquittal. The prosecution must explain any deviation from the chain of custody rule; silence or vague claims of "calling" witnesses will not suffice.
• Genuine efforts must be shown. If required witnesses fail to appear, the police must prove they made serious, actual attempts to secure their presence — not just claim unavailability.
• The burden is on the State. The prosecution has a positive duty to account for any lapses in the chain of custody, even if the defense does not raise them at trial.
• Integrity is everything. The ultimate test is whether the seized drugs presented in court are the same items taken from the accused, free from any suspicion of switching, planting, or contamination.
