Reasonable Doubt in Drug Cases: Strict Chain of Custody Protects Liberty

In a significant ruling, the Supreme Court acquitted an accused in a drug case due to the prosecution's failure to strictly comply with the chain of custody requirements under Republic Act No. 9165. The case of People v. Retada (G.R. No. 239331, July 10, 2019) underscores that the constitutional presumption of innocence prevails when law enforcers breach mandatory procedures, even if the accused appears guilty. This decision serves as a crucial reminder that in drug offenses, the integrity of the seized item—the corpus delicti—is the very foundation of conviction.

The Facts of the Case

On April 7, 2012, police operatives in Ginatilan, Cebu conducted a buy-bust operation against Edson Barbac Retada. The poseur-buyer allegedly purchased one sachet of shabu for ₱400 in marked money. After the arrest, a body search at the police station yielded another sachet of the same substance.

Retada was charged with illegal sale and illegal possession of dangerous drugs under Sections 5 and 11(3), Article II of RA 9165. Both the Regional Trial Court and the Court of Appeals convicted him, ruling that the prosecution had established an unbroken chain of custody.

The Issue

The central issue was whether Retada's guilt was proven beyond reasonable doubt, particularly whether the prosecution sufficiently established compliance with Section 21 of RA 9165 on the custody and disposition of seized drugs.

The Supreme Court's Ruling

The Supreme Court reversed the conviction and acquitted Retada on the ground of reasonable doubt. The Court emphasized that in drug cases, the confiscated substance is the very corpus delicti, and its identity and integrity must be established with moral certainty.

Mandatory Witnesses Were Absent

Section 21 of RA 9165 requires that the physical inventory and photographing of seized items be conducted in the presence of: (1) the accused or his representative or counsel, (2) an elected public official, (3) a representative from the media, and (4) a representative from the Department of Justice (DOJ). In this case, only two councilors were present during the inventory. No media or DOJ representative attended.

The Court rejected the police officers' claim that they "tried to contact" these witnesses upon arriving at the police station. This was not the "earnest effort" contemplated by law. The three required witnesses should already be physically present at the time of inventory, which must be done immediately at the place of seizure.

Inventory Conducted at the Wrong Place

The police conducted the marking, inventory, and photography at the police station, not at the place of arrest. Their excuse—that there were several people in the buy-bust area—was deemed a "flimsy" justification. The Court noted that a buy-bust operation is a planned activity, making it easy to bring the required witnesses to the intended place of arrest.

The "Fruit of the Poisonous Tree" Doctrine

The Court further held that since the warrantless arrest was illegal due to the procedural breaches, the subsequent warrantless search at the police station was likewise invalid. The sachet recovered from that search was inadmissible as "fruit of the poisonous tree."

Practical Takeaways

• Strict compliance is the rule. Police officers must comply with Section 21 of RA 9165, including the presence of all three mandatory witnesses during inventory and photography, done immediately at the place of seizure.
• Non-compliance requires justification. If strict compliance is impossible, the prosecution must prove justifiable grounds and that the integrity of the seized items was preserved. The excuses must be earnest and credible.
• Witnesses must be present at the scene. "Calling in" witnesses after the operation is completed defeats the law's purpose of preventing planting of evidence.
• The burden is on the prosecution. Prosecutors must diligently prove compliance with Section 21 and explain any deviations, or the conviction will be overturned.
• Liberty prevails on doubt. When the chain of custody is broken, the accused is entitled to acquittal on reasonable doubt, regardless of perceived guilt.
