Unlawful Arrests and Drug Possession: Safeguarding Constitutional Rights in Philippine Law

In a significant ruling, the Supreme Court acquitted an accused charged with illegal sale and possession of drugs, emphasizing that strict compliance with the chain of custody rule is essential to protect the integrity of evidence and uphold constitutional rights. The case of People v. Dizon (G.R. No. 223562, September 4, 2019) serves as a reminder that even in drug offenses, the prosecution must prove guilt beyond reasonable doubt, and any breach in the handling of seized items can lead to acquittal.

The Case: A Buy-Bust Operation Under Scrutiny

Lean Noel Dizon was arrested in December 2010 during a buy-bust operation in Siaton, Negros Oriental. He was charged with violating Sections 5 and 11 of Article II of Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002, for allegedly selling 0.15 gram of shabu and possessing another 0.13 gram. The trial court convicted him, and the Court of Appeals affirmed. On appeal, the Supreme Court reversed the conviction.

The Issues Raised

The accused questioned the validity of his warrantless arrest, the absence of the informant's testimony, the alleged bias of a witness, and the integrity of the seized drugs. The Court addressed each issue but focused on the chain of custody—the procedure that ensures the drugs presented in court are the same ones seized from the accused.

The Chain of Custody Rule

Under Section 21 of RA 9165, the apprehending team must immediately conduct a physical inventory and photograph the seized drugs in the presence of the accused or his representative, a media representative, a DOJ representative, and an elected public official. These witnesses must sign the inventory and receive copies. The rule exists to prevent tampering, switching, or planting of evidence.

In Dizon's case, the inventory was conducted at the place of arrest with two barangay officials and a DOJ representative present. However, no media representative witnessed the inventory at the scene. A media representative later signed the inventory at the NBI office but did not actually witness the inventory and photograph of the seized items. The Court ruled this was a serious breach.

The Saving Clause and Its Limits

The Implementing Rules and Regulations of RA 9165 provide a saving clause: non-compliance may be excused if there are justifiable grounds and the integrity of the evidence is preserved. However, the prosecution must prove these grounds as a fact—the Court cannot presume them. In this case, the prosecution offered no explanation for the absence of the media representative, so the saving clause could not apply.

Violation of the Right to Counsel

The Court also noted that the accused signed the certificate of inventory without being informed of his right to counsel or his right not to sign. Citing People v. Del Castillo, the Court held that such a signature, made without assistance of counsel and without a written waiver, violates the constitutional right to counsel. This further undermined the prosecution's case.

Practical Takeaways

• Chain of custody is crucial. In drug cases, the prosecution must account for every link—from seizure and marking to turnover, laboratory examination, and presentation in court. Any unexplained gap can be fatal.
• Witnesses must actually witness. Having a media representative merely sign the inventory later does not cure a breach. The required witnesses must be present during the actual inventory and photograph.
• The saving clause requires proof. Non-compliance with Section 21 is not automatically excused. The prosecution must prove justifiable grounds and that the evidence's integrity was preserved.
• Right to counsel applies. An accused cannot be made to sign documents without being informed of their rights. A waiver must be in writing and made in the presence of counsel.
• Buy-bust operations are valid but not above the law. While warrantless arrests during entrapment are allowed, law enforcers must strictly follow procedural safeguards.
