Chain of Custody Breach Warrants Acquittal in Drug Sale Case

The Supreme Court has reiterated a firm rule in drug cases: when police fail to justify why they conducted the inventory of seized drugs away from the place of arrest, the accused must be acquitted. In People v. Almayda (G.R. No. 227706, June 14, 2023), the Court reversed a conviction for illegal sale of shabu because the prosecution could not explain a critical procedural lapse that broke the chain of custody.

The Facts of the Case

In April 2012, PDEA agents conducted a buy-bust operation against Allan Almayda and Homero Quiogue in Legazpi City. A poseur-buyer purchased two sachets of methamphetamine hydrochloride for P4,500.00. The agents marked the sachets at the scene of the arrest. However, the physical inventory and photograph-taking were done later at the PDEA Regional Office, not at the place of seizure.

The trial court convicted both accused of violating Section 5, Article II of Republic Act No. 9165 (Comprehensive Dangerous Drugs Act of 2002), sentencing each to life imprisonment and a fine of P1,000,000.00. The Court of Appeals affirmed. The Supreme Court initially affirmed, but on reconsideration, reversed and acquitted the accused.

The Issue

The central question was whether the prosecution had established an unbroken chain of custody over the seized drugs. Specifically, the Court examined whether the failure to conduct the inventory at the place of arrest—without any justification—fatally compromised the integrity of the evidence.

The Ruling

The Court ruled that the first link in the chain of custody was already broken. Under Section 21 of R.A. No. 9165, the physical inventory and photograph-taking of seized drugs must generally be done at the place of seizure. The exception—allowing the inventory to be done at the nearest police station or office of the apprehending team—applies only when police provide a sensible, practicable justification, such as the impracticality of doing it at the scene or immediate danger to the items. That justification must be reflected in the police officers' affidavits.

In this case, the prosecution witnesses offered no explanation for conducting the inventory at the PDEA office. Citing People v. Casa (G.R. No. 254208), the Court stressed that compliance with later links in the chain cannot cure an incipient defect in the first link. As held in People v. Ismael (806 Phil. 21 [2017]), once the initial link is broken, there can be no assurance against switching, planting, or contamination of the seized items.

The Court emphasized that while society must combat illegal drugs, law enforcement cannot trample on constitutional rights. Courts must be extra vigilant in drug cases because of the unusually severe penalties involved. The accused were acquitted and ordered immediately released.

Practical Takeaways

• Location matters. In buy-bust operations, the inventory and photographing of seized drugs must be done at the place of arrest, unless a valid exception applies.
• Justification must be documented. If police conduct the inventory elsewhere, they must state a sensible, specific reason in their affidavits—not a generic or afterthought explanation.
• The first link is crucial. A break in the first link of the chain of custody cannot be cured by perfect compliance in later links.
• Prosecution bears the burden. The State must prove every link in the chain of custody beyond reasonable doubt; failure to do so results in acquittal.
• Rights prevail over expediency. The war on drugs does not justify shortcuts that risk convicting the innocent.
