Compromised Chain of Custody Acquittal in Drug Cases Due to Witness Absence

The Supreme Court has once again underscored that in drug cases, the prosecution's failure to justify the absence of required witnesses during the inventory of seized items can be fatal to its case. In People v. Acabo (G.R. No. 241081, February 11, 2019), the Court acquitted an accused because the police failed to explain why a Department of Justice (DOJ) representative and a media representative were not present during the physical inventory of the seized drugs. The ruling serves as a stern reminder to law enforcers and prosecutors that the chain of custody rule is not a mere technicality but a substantive requirement that protects the accused from potential police abuse.

The Facts of the Case

On September 12, 2009, police officers conducted a buy-bust operation against Bernido Acabo in Tagbilaran City, Bohol. Two plastic sachets containing white crystalline substance, later confirmed to be 0.08 gram of methamphetamine hydrochloride or shabu, were recovered from him. Acabo and the seized items were brought to the Garcia-Hernandez Police Station, where an inventory was conducted in the presence of two barangay kagawads and a PDEA representative. The media representative, Dave Charles Responte, only signed the inventory documents later at the Bohol Provincial Police Office.

The Regional Trial Court convicted Acabo of illegal sale of dangerous drugs under Section 5, Article II of Republic Act No. 9165, and the Court of Appeals affirmed the conviction. Acabo appealed to the Supreme Court.

The Issue

The central issue was whether the prosecution had sufficiently established the chain of custody of the seized drugs, particularly whether the absence of the DOJ and media representatives during the inventory was properly justified.

The Ruling: Acquittal Due to Unjustified Deviation

The Supreme Court reversed the conviction and acquitted Acabo. The Court held that the prosecution failed to prove the integrity of the corpus delicti—the dangerous drug itself—which is essential in drug cases.

Under Section 21, Article II of RA 9165, the 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, a representative from the media, and a representative from the DOJ. The presence of these witnesses ensures that there is no switching, planting, or contamination of evidence.

While the law allows non-compliance with these requirements under justifiable grounds, the prosecution must prove two things: (1) that there was a justifiable reason for the non-compliance, and (2) that the integrity and evidentiary value of the seized items were properly preserved. The Court emphasized that the prosecution cannot merely state that the witnesses were unavailable; it must show genuine and sufficient efforts to secure their presence.

In this case, the poseur buyer admitted that the DOJ representative's space on the certificate was blank because "there was no available representative who will sign." The media representative signed the documents only later at the Bohol Provincial Police Office, not at the actual inventory. The Court found these explanations insufficient—mere statements of unavailability, without actual serious attempts to contact the required witnesses, do not constitute a justifiable reason for non-compliance.

The Importance of the Chain of Custody Rule

The Court reiterated that compliance with the chain of custody procedure is strictly enjoined, as it is "not merely a procedural technicality but a matter of substantive law." The rule was crafted by Congress as a safety precaution against police abuses, especially considering that the penalty for drug offenses can be life imprisonment.

The Court also cited People v. Miranda, reminding prosecutors that the State has a positive duty to account for any lapses in the chain of custody, regardless of whether the defense raises the issue at trial. A conviction can be overturned on appeal if the evidence's integrity and evidentiary value are compromised.

Practical Takeaways

• Police must secure required witnesses. In buy-bust operations, the apprehending team must make genuine efforts to secure the presence of an elected public official, a media representative, and a DOJ representative during the inventory. These efforts must be documented and proven in court.
• Mere statements of unavailability are not enough. If a required witness is absent, the prosecution must explain the specific reasons and show that the police actually tried to contact the witness. Vague claims of unavailability will not satisfy the saving clause.
• Witnesses must actually witness the inventory. A witness who signs the inventory documents later, without being present during the actual inventory and photography, does not satisfy the legal requirement.
• The defense need not raise the issue early. The prosecution must prove the chain of custody even if the defense does not object during trial. Lapses can be raised for the first time on appeal.
• The stakes are high. Failure to justify deviations from the chain of custody rule can lead to acquittal, even when the accused was caught with drugs in a legitimate buy-bust operation.
