Constructive Possession Knowledge AND Control IN Drug Cases

The prosecution of drug offenses under Republic Act No. 9165, the Comprehensive Dangerous Drugs Act, requires more than the mere recovery of prohibited substances. The State must prove every element of the crime, including the accused's possession of the drug with knowledge and control over it. In People v. Placiente (G.R. No. 213389, August 14, 2019), the Supreme Court underscored this principle, reversing a conviction where police procedural lapses cast doubt on the integrity of the evidence.

The Facts of the Case

On January 24, 2005, police officers in Quezon City conducted a buy-bust operation against Ebo Placiente y Tejero based on information from a confidential informant. PO2 Reas acted as the poseur-buyer and handed Placiente P200 in marked money. Placiente allegedly sold one sachet of shabu to the officer. After the pre-arranged signal, another officer searched Placiente and found a second sachet in his pants pocket.

Placiente was charged with illegal sale and illegal possession of dangerous drugs. The Regional Trial Court convicted him, and the Court of Appeals affirmed. On appeal, the Supreme Court reversed the conviction, acquitting Placiente on the ground of reasonable doubt.

The Issue: Proving Possession Beyond Reasonable Doubt

The central question was whether the prosecution had established Placiente's guilt beyond reasonable doubt, particularly regarding the integrity of the seized drugs and the regularity of the police operation. The Court emphasized that in drug cases, the corpus delicti—the body of the crime—is the dangerous drug itself. The State must present the seized drug and prove there were no substantial gaps in the chain of custody from confiscation to presentation in court.

The Ruling: Procedural Lapses and Reasonable Doubt

The Supreme Court found several fatal lapses in the police officers' compliance with Section 21 of R.A. No. 9165:

Failure to mark and inventory at the place of arrest. The officers conducted the inventory at the police station, not at the scene. PO2 Reas claimed the area was "critical," but the Court found this excuse self-serving and unsupported by evidence. The law requires immediate marking and inventory at the place of arrest, or at the nearest police station where practicable.

Absence of required witnesses. No elected public official, DOJ representative, or media representative witnessed the inventory. The inventory document was not even signed by the required witnesses.

No photographs taken. The officers failed to photograph the seized items. PO2 Reas said the station had no camera, a justification the Court called "ridiculous," noting that virtually all cellular phones at the time were equipped with cameras.

No explanation for non-compliance. The arresting officers did not provide a credible explanation for their deviations from the prescribed procedure. Under People v. Lim, the prosecution bears the burden of proving a valid cause for non-compliance with Section 21. Mere mention of a justifiable ground is insufficient; the officers must state it in their sworn affidavit and show the steps taken to preserve the integrity of the seized items.

The Court also noted that the pre-operation report indicated the operation targeted a different person, and a defense witness testified that Placiente was arrested only after officers failed to find their intended target. These circumstances corroborated Placiente's defense.

Why This Matters for Constructive Possession

While the case involved actual physical possession, its principles apply equally to constructive possession—where the drug is found in a place under the accused's control, such as a vehicle, house, or bag. To prove constructive possession, the prosecution must show:

1. Knowledge—the accused knew of the presence of the drug;
2. Control—the accused had the power and intent to possess or dispose of it.

When police fail to follow the chain-of-custody rules, the identity and integrity of the seized drug become suspect. If the drug itself cannot be reliably identified, the prosecution cannot prove that the accused possessed a dangerous drug at all.

Practical Takeaways

• Chain of custody is critical. The prosecution must present the seized drug and prove an unbroken chain from seizure to trial. Gaps create reasonable doubt.
• Compliance with Section 21 is mandatory. Marking, inventory, and photographing must be done in the presence of the accused and required witnesses. Non-compliance requires a credible, documented explanation.
• The presumption of regularity is not automatic. When officers deviate from procedure, they lose the presumption of regularity in the performance of their duties. The prosecution must prove regularity.
• Small quantities require stricter scrutiny. Where the seized amount is minuscule, it is highly susceptible to planting, tampering, or alteration. Courts demand stricter adherence to procedure.
• For constructive possession, knowledge and control must be proven. Mere presence near a drug is not enough. The prosecution must show the accused knew of the drug and had the power to control it.
