Navigating the Chain of Custody: Safeguarding Rights in Drug Cases

In a significant ruling, the Supreme Court reversed the conviction of two individuals for illegal sale of dangerous drugs, emphasizing that law enforcers must strictly comply with the chain of custody rule under Republic Act No. 9165. The case of People v. Libre (G.R. No. 235980, August 20, 2018) serves as a crucial reminder that the government's war on drugs cannot justify shortcuts that compromise an accused person's right to due process.

The case arose from a buy-bust operation in Cebu City, where police officers allegedly seized a plastic sachet containing 24.80 grams of methamphetamine hydrochloride, or shabu, from Joseph and Leonila Libre. The accused were charged with illegal sale of dangerous drugs under Section 5, Article II of RA 9165, and were convicted by the Regional Trial Court and later the Court of Appeals. Leonila appealed to the Supreme Court, arguing that the prosecution failed to establish an unbroken chain of custody over the seized drugs.

The Issue

The central question before the Court was whether the accused's conviction for illegal sale of dangerous drugs should be upheld despite alleged procedural lapses in the handling of the seized evidence.

The Chain of Custody Requirement

To convict an accused of illegal sale of dangerous drugs, the prosecution must prove the identity of the buyer and seller, the object, and the consideration, as well as the delivery of the item and payment. Crucially, the prosecution must also present the dangerous drugs themselves—the corpus delicti—and demonstrate an unbroken chain of custody from seizure to presentation in court.

Under Section 21, Article II of RA 9165, as it stood before its amendment by RA 10640, the apprehending team was required to conduct a physical inventory and photograph the seized items immediately after confiscation in the presence of:

• The accused or his representative or counsel
• A representative from the media
• A representative from the Department of Justice (DOJ)
• Any elected public official

These witnesses were required to sign the inventory and receive copies of the same. The presence of these witnesses was intended to eliminate any suspicion of tampering, switching, planting, or contamination of evidence.

The Saving Clause and Its Limits

The Court acknowledged that non-compliance with Section 21 does not automatically invalidate the seizure and custody of the drugs. Under the saving clause, the prosecution may still prevail if it proves: (a) there was a justifiable ground for the non-compliance, and (b) the integrity and evidentiary value of the seized items were properly preserved.

However, the Court emphasized that the prosecution cannot simply invoke the saving clause without explanation. Citing People v. Umipang, the Court stressed that the prosecution must establish that genuine and earnest efforts were made to secure the presence of the required witnesses. A mere statement that representatives were unavailable, without detailing the steps taken, is a "flimsy excuse" that will not be accepted.

The Fatal Lapse

In this case, the police officers conducted the inventory and photography in the presence of the accused, media representatives, and a barangay councilor—but no DOJ representative was present. The officers' affidavits merely stated that "the team exerted efforts to contact any representative from the Department of Justice but to no avail."

The Supreme Court found this statement insufficient. It was a general conclusion bereft of any discernible detail regarding the specific steps and efforts undertaken to secure the DOJ representative's presence. The officers did not explain whether they attempted to contact other DOJ offices or representatives, or why such efforts failed.

The Court reiterated that the procedure under Section 21 is a matter of substantive law, not a mere procedural technicality that can be brushed aside. Given the unjustified breach, the Court concluded that the integrity and evidentiary value of the corpus delicti had been compromised, warranting acquittal.

Effect on the Non-Appealing Co-Accused

Interestingly, only Leonila appealed her conviction. Her co-accused, Joseph, did not. Nevertheless, the Court applied Section 11(a), Rule 122 of the Revised Rules of Criminal Procedure, which provides that a favorable judgment for one accused shall benefit co-accused who did not appeal. Since Leonila's acquittal was based on a ground applicable to both, Joseph was likewise acquitted.

Practical Takeaways

• Strict compliance is mandatory. Police officers must follow the chain of custody procedure under Section 21 of RA 9165 to the letter, or risk having the seized drugs declared inadmissible.
• Document your efforts. If a required witness (such as a DOJ representative) cannot be secured, the prosecution must present concrete evidence of earnest efforts made—not just a bare assertion of unavailability.
• The saving clause is not automatic. Non-compliance will only be excused if the prosecution proves justifiable grounds and preserves the integrity of the evidence.
• Substantive, not technical. The chain of custody rule is a matter of substantive law designed to protect the accused from evidence tampering or planting.
• Appeals benefit co-accused. A favorable ruling on appeal can extend to co-accused who did not appeal, under the rules of criminal procedure.
