Chain of Custody and Presumption of Regularity in Drug Cases: Tionco v. People

In Tionco v. People (G.R. No. 192284, March 11, 2015), the Supreme Court affirmed the conviction of a man found possessing a small sachet of shabu, clarifying important rules on the chain of custody requirement under Republic Act No. 9165 and the presumption of regularity in the performance of police duties. The case offers practical guidance on what the prosecution must prove in drug possession cases and when lapses in procedure will—and will not—be fatal to a conviction.

The Facts of the Case

On July 24, 2002, police officers PO1 Joel Sta. Maria and PO1 Fernando Reyes were conducting an anti-criminality patrol in Parola Compound, Tondo, Manila. From about three meters away, they saw petitioner Alex Tionco holding and examining a plastic sachet containing a white crystalline substance believed to be shabu. The officers approached, confiscated the sachet, and arrested Tionco after apprising him of his constitutional rights.

At the police station, PO1 Sta. Maria marked the sachet with Tionco's initials "ATO" and turned it over to investigator PO1 Garcia. The seized item was then brought to the Western Police District Crime Laboratory, where Forensic Chemist P/Insp. Judycel Macapagal tested the contents and found them positive for methamphetamine hydrochloride, or shabu. The sachet weighed 0.047 gram.

Tionco denied the charge, claiming he was arrested without cause and that the police demanded P6,000.00 for his release. The trial court convicted him, and the Court of Appeals affirmed. Tionco appealed to the Supreme Court, arguing that the prosecution failed to prove the integrity and identity of the confiscated shabu because no physical inventory was conducted and no photograph of the seized item was taken.

The Elements of Illegal Possession of Dangerous Drugs

The Court reiterated the three elements the prosecution must establish for illegal possession of dangerous drugs under Section 11, Article II of R.A. 9165:

1. The accused is in possession of an item identified to be a prohibited drug;
2. Such possession is not authorized by law; and
3. The accused freely and consciously possessed the drug.

In this case, the prosecution established all three elements. PO1 Sta. Maria positively identified Tionco as the person holding the plastic sachet and identified the sachet marked "ATO" as the same item confiscated from him. There was no evidence that Tionco was authorized to possess the drug, and having been caught in flagrante delicto, there was prima facie evidence that he freely and consciously possessed it.

Chain of Custody: Substantial Compliance Is Enough

The Court addressed Tionco's argument that the police failed to comply with Section 21 of R.A. 9165, which requires a physical inventory and photograph of seized drugs immediately after seizure.

While the Court acknowledged that no physical inventory was conducted and no photograph was taken, it ruled that these lapses were not fatal. What matters most, the Court said, is the preservation of the integrity and evidentiary value of the seized items.

The Court found the chain of custody was not broken: the sachet was confiscated from Tionco, marked with his initials at the police station, turned over to the investigator, delivered to the crime laboratory, and positively identified in court by PO1 Sta. Maria as the same item seized.

Significantly, the Court also noted that Tionco never questioned the admissibility of the seized item during trial. He raised the chain of custody issue only on appeal. The Court applied the settled rule that no question will be entertained on appeal unless it was raised in the court below.

Presumption of Regularity and Credibility of Witnesses

The Court also gave weight to the presumption of regularity in the performance of official duties by the police officers, noting that there was no evidence of improper motive on their part. Tionco's defenses of denial and extortion were rejected as self-serving and uncorroborated.

The Court likewise dismissed Tionco's argument that it was improbable for him to openly hold a sachet of shabu in broad daylight. As the Court observed, drug pushers have become increasingly daring and openly defiant of the law. What matters is not the time or place of the violation, but the acts constituting it.

Minor inconsistencies in a witness's testimony—such as whether Tionco was facing his companion or leaning on a wall—were deemed trivial and inconsequential, and did not destroy the witness's credibility.

The Penalty Imposed

The Court affirmed the indeterminate sentence of twelve (12) years and one (1) day to fifteen (15) years, plus a fine of P300,000.00, which is within the range prescribed by Section 11(3), Article II of R.A. 9165 for possession of less than five grams of shabu.

Practical Takeaways

• Chain of custody is about integrity, not perfect paperwork. Minor lapses in procedure, such as the absence of a physical inventory or photograph, will not automatically result in acquittal if the prosecution can show the seized item's integrity and evidentiary value were preserved.
• Raise procedural objections at trial. A party cannot raise the chain of custody issue for the first time on appeal. Objections to the admissibility of evidence must be made in the trial court.
• The presumption of regularity matters. Police officers are presumed to have performed their duties regularly, and this presumption stands unless the defense presents clear and convincing evidence of improper motive.
• Denial and extortion defenses are weak without corroboration. Self-serving allegations of frame-up or extortion, unsupported by strong evidence, will not overcome the positive testimony of prosecution witnesses.
• The elements of illegal possession are straightforward. The prosecution must prove possession of a prohibited drug, lack of authorization, and conscious possession. Being caught in flagrante delicto creates prima facie evidence of conscious possession.
