Challenging Drug Evidence: Strict Compliance for Miniscule Amounts

In drug cases, the prosecution must prove not only that the accused possessed an illegal substance, but also that the item presented in court is exactly the same item seized from the accused. This is the essence of the chain of custody rule under Section 21 of Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002. In People v. Aparente (G.R. No. 205695, September 27, 2017), the Supreme Court emphasized that when the amount of drugs seized is miniscule, the police must comply with these rules even more strictly. The Court acquitted the accused because the arresting team failed to mark the seized sachet immediately, and no justifiable reason was given for this lapse.

The Facts of the Case

On the evening of February 13, 2006, police officers on surveillance in Binangonan, Rizal saw a man hand Jesus Aparente a small plastic sachet. Aparente inspected the sachet by flicking it against the light. When the officers approached, the two men fled; only Aparente was caught. The officers found a sachet containing a white crystalline substance, later confirmed to be 0.01 gram of methamphetamine hydrochloride, or shabu. Aparente was charged with illegal possession of dangerous drugs under Section 11 of RA 9165.

Aparente claimed he was at home watching television when five men forcibly entered, handcuffed him, and coerced him into admitting possession. The trial court found the police officers credible and convicted Aparente, imposing a sentence of 12 years and one day to 13 years, with a fine of P300,000. The Court of Appeals affirmed.

The Issue Before the Supreme Court

Two issues were raised on appeal. First, whether the warrantless arrest and search violated Aparente's constitutional rights. Second, whether the failure to explain the lack of immediate marking, inventory, and photographing of the seized drugs negated their evidentiary value.

The Warrantless Arrest Was Valid

The Court first addressed the arrest. The Constitution protects against unreasonable searches and seizures, but warrantless arrests and searches are permitted in certain situations, including when a search is incidental to a lawful arrest. Aparente argued that the search preceded his arrest, which he claimed was invalid.

The Court disagreed. While an arrest generally must precede a search, a search that is substantially contemporaneous with an arrest can be valid if the police had probable cause to arrest at the outset. Here, the officers personally observed a hand-to-hand exchange of a small sachet in an alley, followed by the suspects fleeing upon the officers' approach. These overt acts gave the police reasonable suspicion that a drug offense was being committed. The warrantless arrest and the incidental search were therefore lawful.

The Chain of Custody Was Broken

The more critical issue was compliance with Section 21 of RA 9165. This provision requires the apprehending team to physically inventory and photograph the seized drugs immediately after seizure, in the presence of the accused, a representative from the media, a representative from the Department of Justice, and an elected public official. The implementing rules state that the inventory and photographing should be done at the place of seizure or at the nearest police station, and that non-compliance may be excused only under justifiable grounds, provided the integrity of the evidence is preserved.

In this case, the arresting officers did not mark the seized sachet at the scene. Instead, an investigating officer at the police station marked it with Aparente's initials. The prosecution offered no explanation for this deviation from the standard procedure. The Court found this significant.

Citing its earlier ruling in People v. Holgado, the Court stressed that where only a miniscule amount of drugs is seized, trial courts must require a more exacting compliance with Section 21. The rationale is simple: when the quantity is tiny, the risk of tampering, substitution, or contamination is greater, and the integrity of the evidence becomes even more crucial. The failure to mark the drugs immediately, combined with the absence of any justifiable reason, cast doubt on the identity and integrity of the seized item. The Court reversed the conviction and acquitted Aparente.

Practical Takeaways

• Strict compliance is required for small amounts. Courts will scrutinize the chain of custody more closely when the quantity of drugs seized is miniscule, because the evidence is more vulnerable to tampering.
• Marking must be immediate. The apprehending team must mark the seized drugs at the scene or as soon as practicable. Having an investigator mark the items later at the police station, without explanation, is a fatal flaw.
• Non-compliance needs justification. The law excuses deviations from Section 21 only under justifiable grounds. The prosecution must explain any lapse and show that the integrity of the evidence was preserved.
• Warrantless arrests can still be valid. A search that precedes an arrest is permissible if the two acts are substantially contemporaneous and the police had probable cause based on observed overt acts.
• The presumption of regularity is not automatic. The presumption of regularity in the performance of official duties cannot override the prosecution's burden to prove compliance with the law, especially when the defense raises specific lapses.
