Chain of Custody Safeguarding Drug Evidence and Ensuring Fair Trials in the Philippines

In People v. Royol (G.R. No. 224297, February 13, 2019), the Supreme Court reversed a conviction for illegal sale of dangerous drugs because police officers failed to comply with the chain of custody requirements under Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002. The ruling underscores a vital principle: the prosecution cannot rely on the presumption of regularity in the performance of official duties to excuse noncompliance with the law's mandatory procedures. This decision reinforces the constitutional presumption of innocence, reminding law enforcers that the integrity of seized evidence is paramount in drug cases.

The Facts of the Case

In November 2007, a confidential informant reported to the Tarlac Provincial Police Office that Edgardo Royol, a garbage collector, was selling illegal drugs. A buy-bust team was formed, with PO2 Mark Anthony Baquiran acting as poseur-buyer. The team proceeded to a bridge in Barangay Lourdes, Bamban, Tarlac, where Royol allegedly sold half a brick of dried marijuana weighing 500.28 grams to PO2 Baquiran for P1,000.00. Royol was arrested, and the marijuana was brought to the Tarlac Provincial Crime Laboratory, where it tested positive for marijuana.

Royol denied the charges. He claimed that two men approached him while he was collecting garbage, asked about a certain Edgardo Saguisag, and later returned with two teenagers who pointed to him as Saguisag. He was handcuffed, searched, and brought to Camp Makabulos, where he was shown marijuana and asked if it was his.

The Regional Trial Court convicted Royol, imposing life imprisonment and a fine of P500,000.00. The Court of Appeals affirmed the conviction. Royol appealed to the Supreme Court.

The Issue

The central issue was whether the prosecution established Royol's guilt beyond reasonable doubt for violating Section 5 of RA 9165. The Court focused on whether the chain of custody requirements under Section 21 of the law were properly observed.

The Chain of Custody Rule

Section 21 of RA 9165, as amended by RA 10640, requires the apprehending team to conduct a physical inventory and photograph the seized items immediately after seizure and confiscation. This must be done in the presence of the accused or his representative or counsel, an elected public official, and a representative of the National Prosecution Service or the media. These witnesses must sign the inventory and receive copies.

Jurisprudence, as cited in the decision, identifies four links in the chain of custody: (1) seizure and marking of the illegal drug by the apprehending officer; (2) turnover to the investigating officer; (3) turnover to the forensic chemist for laboratory examination; and (4) turnover and submission to the court. Compliance protects the integrity of the evidence, foreclosing opportunities for planting, contamination, or tampering.

The Ruling

The Supreme Court acquitted Royol. The prosecution failed to establish even a semblance of compliance with Section 21(1). Neither the poseur-buyer nor the arresting officer testified about conducting a proper inventory or photographing the seized marijuana. There was no proof that any of the required third-party witnesses—an elected public official, a representative of the National Prosecution Service, or the media—was present. The prosecution merely claimed that the marijuana was marked at the police station.

The Court rejected the lower courts' reliance on the presumption of regularity in the performance of official duties. As explained in People v. Kamad, the presumption applies only when officers have shown compliance with the standard conduct of official duty required by law. Where the official act is irregular on its face, the presumption cannot arise.

The Court also noted that while Section 21(1) allows deviations under "justifiable grounds," the prosecution must specifically allege and prove such grounds and show that the integrity and evidentiary value of the seized items were preserved. In this case, the prosecution offered no justification at all.

Practical Takeaways

• Strict compliance is mandatory. Police officers must follow Section 21 of RA 9165 to the letter. Approximating compliance—such as merely marking the seized items without a proper inventory and photographing—is insufficient.

• Third-party witnesses are essential. The presence of an elected public official, a representative of the National Prosecution Service, and the accused or his representative during the inventory and photographing serves as an "insulating presence" against switching, planting, or contamination of evidence.

• The presumption of regularity is not a shield. Law enforcers cannot rely on the presumption of regularity in the performance of official duties to excuse noncompliance with statutory requirements. The presumption applies only when there is actual compliance with the law.

• The prosecution must explain deviations. If the police fail to comply with Section 21, the prosecution must specifically allege and prove justifiable grounds and demonstrate that the integrity of the seized items was preserved.

• The burden rests on the prosecution. In criminal cases, the prosecution must prove guilt beyond reasonable doubt based on the strength of its own evidence. It cannot bank on the weakness of the defense.

A Reminder of Constitutional Rights

People v. Royol is a reminder that the fight against illegal drugs must never come at the expense of constitutional rights. The Court acknowledged the urgency of addressing the drug menace but emphasized its duty to ensure compliance with laws and uphold basic freedoms. When law enforcers disregard the bare minimum that RA 9165 requires, acquittal must follow.
