Chain of Custody in Drug Cases: When Minor Gaps Won't Overturn a Conviction

In drug cases, the prosecution must prove not only that the accused possessed illegal drugs, but also that the drugs presented in court are the very same items seized from the accused. This is the essence of the "chain of custody" rule. In People v. Dimaano (G.R. No. 174481, February 10, 2016), the Supreme Court clarified that minor inconsistencies in the handling of seized drugs do not automatically warrant acquittal, so long as the identity and integrity of the drugs are preserved.

The Facts of the Case

On November 13, 2002, Non-Uniformed Personnel Florence Bilugot, a frisker at the Manila Domestic Airport Terminal 1, noticed a hard object bulging near the buttocks of departing passenger Cristy Dimaano. When asked, Dimaano claimed it was a sanitary napkin. Suspicious, Bilugot brought Dimaano to the ladies' room for a closer inspection.

There, Bilugot found a plastic sachet containing a white crystalline substance hidden under Dimaano's sanitary napkin. Dimaano allegedly admitted it was "shabu" and said she was merely asked to bring it. Bilugot turned the sachet over to SPO2 Reynato Ragadio, who was waiting outside.

The sachets were eventually submitted to the Philippine National Police Crime Laboratory, where Forensic Chemist Police Inspector Abraham Tecson confirmed that the contents tested positive for methamphetamine hydrochloride, weighing 13.96 grams. Dimaano was charged with attempted transportation of dangerous drugs under Section 5, in relation to Section 26, of Republic Act No. 9165 (the Comprehensive Dangerous Drugs Act of 2002).

The Issue: A Break in the Chain of Custody?

Dimaano argued that inconsistencies in the testimonies of the prosecution witnesses created a break in the chain of custody. Specifically, Bilugot testified that she recovered only one plastic sachet from Dimaano, while SPO2 Ragadio testified that he received two plastic sachets from Bilugot. Dimaano also pointed out that the seven smaller sachets inside the two outer sachets were not marked with the arresting officers' initials.

The trial court convicted Dimaano, and the Court of Appeals affirmed. The case reached the Supreme Court, which had to determine whether the prosecution sufficiently established an unbroken chain of custody.

The Ruling: Substantial Compliance Suffices

The Supreme Court affirmed Dimaano's conviction. The Court explained that while Section 21 of RA 9165 prescribes the proper procedure for handling seized drugs, the rule does not require perfect compliance. What matters is that the integrity and evidentiary value of the seized items are preserved.

On the discrepancy in the number of sachets, the Court found it insignificant. The forensic chemist testified that he received two plastic sachets marked with "FSB" (Bilugot's initials), "RBR" (Ragadio's initials), and "RSA." This corroborated Ragadio's testimony that he received two sachets from Bilugot. Bilugot's failure to remember the contents of the sachet she seized was excusable, as witnesses cannot be expected to recall every detail of an incident with perfect accuracy.

The Court also addressed the failure to mark the seven smaller sachets. It noted that marking the corpus delicti is required only "as far as practicable." Here, the two outer sachets were heat-sealed, and opening them to mark the inner sachets would have risked contaminating the specimen. The markings on the outer sachets were sufficient to preserve the identity of the drugs.

Why the Airline Ticket Was Not Essential

Dimaano also argued that the prosecution failed to present her airline ticket, which would have proven her intention to board a flight to Cebu. The Court rejected this argument, holding that the prosecution need not present the ticket to prove intent. Dimaano had submitted herself to body frisking at the airport, and the discovery of 13.96 grams of shabu on her person was sufficient to establish that she was attempting to transport the drugs.

Practical Takeaways

• Substantial compliance is enough. Law enforcement need not follow Section 21 of RA 9165 to the letter. Minor deviations are excusable as long as the integrity of the seized drugs is preserved.
• Minor inconsistencies in testimony are not fatal. Witnesses are not expected to have perfect recall. Courts look at the overall credibility of witnesses and the consistency of material facts.
• Marking requirements are flexible. The law requires marking only "as far as practicable." If opening a sealed package would risk contamination, marking the outer packaging may suffice.
• The identity of the drugs is paramount. The prosecution's main burden is to prove that the drugs examined and presented in court are the very same items seized from the accused.
• Airport security personnel are presumed regular. Absent evidence of ill motive, courts give credence to the testimonies of law enforcement officers who performed their duties in a regular manner.
