Upholding Conviction Despite Procedural Lapses in Chain of Custody in Drug Cases

The Supreme Court, in People v. Cabiles (G.R. No. 220758, June 7, 2017), affirmed the conviction of an accused for illegal sale of shabu under Section 5, Article II of Republic Act No. 9165, despite the defense's claim of procedural lapses in the chain of custody of the seized drug. The ruling clarifies that not every deviation from the prescribed procedure automatically destroys the integrity of the evidence, provided that the prosecution sufficiently establishes an unbroken chain of custody.

Facts of the Case

On October 31, 2005, police officers conducted a buy-bust operation against Stephan Cabiles y Suarez, who was suspected of selling illegal drugs in Bacolod City. PO1 Ian Piano acted as the poseur-buyer and handed two P100 bills to the accused in exchange for one heat-sealed plastic sachet containing methamphetamine hydrochloride, or shabu, weighing 0.04 gram.

After the exchange, the accused was arrested. The arresting officer immediately placed the markings "ISP" on the seized sachet at the scene and in the presence of the accused. The accused was then brought to the barangay hall for inventory, and the seized item was later delivered to the PNP Crime Laboratory, which confirmed it was positive for shabu.

The accused denied the charges, claiming he was arrested while buying rice and sardines at a sari-sari store, and that the police merely planted evidence against him.

Issue Before the Court

The central issue was whether the conviction for illegal sale of dangerous drugs should stand despite alleged procedural lapses in the chain of custody, particularly the failure to photograph the seized substance in the accused's presence and the reliance on a barangay certification instead of a full inventory.

The Ruling

The Supreme Court dismissed the appeal and affirmed the conviction. The Court held that the prosecution had established all the elements of illegal sale of dangerous drugs: the identity of the buyer and seller, the object and consideration, and the delivery of the drug and payment therefor. The act of handing over the shabu in exchange for marked money consummated the sale.

On the chain of custody issue, the Court ruled that the integrity and evidentiary value of the seized item were properly preserved. The marking was done immediately at the scene, the item was inventoried at the barangay hall, and it was delivered to the crime laboratory where it tested positive for shabu. These steps showed an unbroken chain of custody.

The Court also applied the presumption of regularity in the performance of official duties by law enforcement officers. Since the accused failed to present clear and convincing evidence of improper motive or irregularity, the presumption stood. The defense of denial was deemed weak and self-serving, unable to overcome the positive testimony of prosecution witnesses.

Practical Takeaways

• Chain of custody is about integrity, not perfection. Minor deviations from the prescribed procedure will not automatically result in acquittal if the prosecution can show that the seized item's integrity and evidentiary value were preserved throughout.
• Immediate marking is crucial. Marking the seized item at the scene of the operation, in the presence of the accused, significantly strengthens the prosecution's case.
• The presumption of regularity applies. Police officers enjoy the presumption of regularity in performing their duties. To overcome this, the defense must present clear and convincing evidence of improper motive or serious procedural violations.
• Denial is a weak defense. An unsupported denial cannot prevail against the positive and straightforward testimony of prosecution witnesses, especially when corroborated by other evidence.
• Penalty for illegal sale of shabu. Under R.A. 9165, the penalty for unauthorized sale of dangerous drugs, regardless of quantity, is life imprisonment and a fine ranging from P500,000 to P10 million, with the death penalty no longer imposed following R.A. 9346.
