Chain of Custody and Reasonable Doubt: Safeguarding Rights in Drug Cases

In a significant ruling that underscores the importance of procedural compliance in drug cases, the Supreme Court acquitted Cesaria Basio Vertudes and her son Henry Basio Vertudes of illegal sale and possession of dangerous drugs. The Court reversed the convictions handed down by the trial court and the Court of Appeals, emphasizing that the prosecution's failure to establish an unbroken chain of custody over the seized drugs created reasonable doubt as to the accused's guilt.

The Case Before the Court

The accused were arrested on April 17, 2010, in Parañaque City during a buy-bust operation. Police officers claimed that Henry sold two plastic sachets of methamphetamine hydrochloride (shabu) to a poseur-buyer, while Cesaria was found in possession of another sachet and the marked money. Both were charged with violating Sections 5 and 11 of Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002.

The prosecution's witnesses testified that the seized items were marked at the scene of the arrest. However, because a crowd had formed, the police proceeded to the barangay hall to conduct the inventory. There, the inventory was witnessed only by a Barangay Ex-O and a Barangay Tanod, both of whom were not among the witnesses required by law.

The Chain of Custody Rule

In drug cases, the confiscated drug is the very corpus delicti of the offense—the body of the crime. Its existence and identity must be established with moral certainty. The prosecution must show an unbroken chain of custody over the seized items from the moment of seizure up to their presentation in court.

Section 21, Article II of RA 9165, which was the applicable law at the time, requires that the seized items be inventoried and photographed immediately after seizure. This must be done in the presence of:

• The accused or his representative or counsel
• An elected public official
• A representative from the media
• A representative from the Department of Justice

The Court stressed that these witnesses should already be physically present at the time of the inventory, which must be done at the place of seizure. Since a buy-bust operation is a planned activity, the buy-bust team could easily have ensured compliance.

The Police's Procedural Lapses

The Court found that the buy-bust team blatantly disregarded the requirements of Section 21. None of the three required witnesses was present at the time of arrest and seizure. Only two Barangay Tanods witnessed the inventory at the barangay hall.

The Court pointed out that a Barangay Tanod is not an elected public official—they are merely appointed by the Sangguniang Barangay. The law specifically requires the presence of an elected public official.

More importantly, the prosecution offered no justifiable reason for the deviation. The police claimed they transferred to the barangay hall because relatives of the accused were "meddling" with the operation, but they did not allege any threat to their safety or show that they made earnest efforts to secure the presence of the required witnesses.

Presumption of Innocence Prevails

The Court reiterated that the presumption of regularity in the performance of official duties cannot overcome the stronger constitutional presumption of innocence in favor of the accused. When there are several procedural lapses that cast doubt on the regularity of the police officers' actions, the presumption of regularity cannot stand.

The Court noted that the prosecution has the burden of proving compliance with Section 21 and providing a sufficient explanation in case of non-compliance. It cited examples of acceptable justifications, such as the remoteness of the arrest location, threats to witness safety, or earnest but futile efforts to secure witnesses. None of these circumstances existed in this case.

Practical Takeaways

• Compliance with Section 21 is mandatory. The three-witness requirement—elected public official, media representative, and DOJ representative—must be satisfied during the inventory and photographing of seized drugs.
• The chain of custody must be unbroken. Every link, from seizure to court presentation, must be accounted for to preserve the integrity and evidentiary value of the drugs.
• Justifiable reasons are required for non-compliance. Merely claiming that a crowd formed or relatives interfered is not enough. The prosecution must present concrete evidence of justifiable grounds.
• Presumption of regularity is not automatic. When police procedures are blatantly disregarded, the presumption of regularity in official duty cannot overcome the accused's presumption of innocence.
• Prosecutors must be vigilant. They are duty-bound to prove compliance with Section 21 and to acknowledge and explain any deviations from the prescribed procedure.
