Chain of Custody in Drug Cases: When Noncompliance Means Acquittal

In a significant ruling on the strict requirements for drug prosecutions, the Supreme Court acquitted an accused charged with illegal sale of marijuana because police officers failed to comply with the chain of custody rules under Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002. The case of People v. Royol (G.R. No. 224297, February 13, 2019) underscores that convictions in drug cases cannot rest on the mere presumption of regularity in the performance of official duties when law enforcers have disregarded statutory safeguards.

The Facts of the Case

Edgardo Royol was arrested in a buy-bust operation in Bamban, Tarlac in November 2007. Police claimed that Royol sold half a brick of dried marijuana fruiting tops, weighing 500.28 grams, to a poseur-buyer for P1,000. The buy-bust team brought Royol to the Tarlac Provincial Police Office, where the marijuana was supposedly marked. The poseur-buyer then personally brought the seized item to the crime laboratory, where it tested positive for marijuana.

Royol denied the charges, claiming he was merely collecting garbage when two men approached him, handcuffed him, and brought him to the police station. He insisted the marijuana was not his.

Both the Regional Trial Court and the Court of Appeals convicted Royol, relying on the presumption of regularity in the performance of official duties by the police officers. The Supreme Court reversed these rulings.

The Issue and the Ruling

The central question was whether the prosecution had established Royol's guilt beyond reasonable doubt for violating Section 5 of RA 9165. The Court ruled that it had not, due to the prosecution's failure to comply with the chain of custody requirements under Section 21 of the same law.

The Chain of Custody Requirement

Section 21 of RA 9165 requires that immediately after seizure and confiscation, the apprehending team must conduct a physical inventory and photograph the seized items in the presence of: (1) the accused or his representative or counsel; (2) an elected public official; and (3) a representative of the National Prosecution Service or the media. These witnesses must sign the inventory and receive copies.

The Court cited People v. Nandi, which identified four links in the chain of custody: (1) seizure and marking of the illegal drug; (2) turnover to the investigating officer; (3) turnover to the forensic chemist for examination; and (4) turnover and submission to the court.

In this case, the prosecution presented no evidence of any physical inventory or photographing. Neither the poseur-buyer nor the arresting officer testified about conducting a proper inventory. There was no elected public official, no representative from the National Prosecution Service, and no media representative present. The prosecution did not even establish that the accused himself was present during the marking of the seized item.

Presumption of Regularity Cannot Save the Prosecution

The Court rejected the lower courts' reliance on the presumption of regularity in the performance of official duties. The Court explained that this 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 emphasized that the prosecution's self-serving assurances about the integrity of the seized drugs cannot replace the objective requirements imposed by statute. As stated in People v. Que, the presence of third-party witnesses serves as an "insulating presence" against the evils of switching, planting, or contamination of evidence.

Justifiable Grounds for Noncompliance

While Section 21 allows for deviations under "justifiable grounds," the prosecution must specifically allege, identify, and prove such grounds. It must also establish that despite noncompliance, the integrity and evidentiary value of the seized items were properly preserved. Broad justifications and sweeping guarantees will not suffice.

In this case, the prosecution never even attempted to account for any justifiable ground for its failure to comply with the requirements.

Practical Takeaways

• Strict compliance is required. Mere marking of seized items is insufficient. The law requires physical inventory and photographing in the presence of specified witnesses.
• Third-party witnesses are essential. The presence of an elected public official and a representative of the National Prosecution Service or media is mandatory, not optional.
• Presumption of regularity has limits. It cannot be invoked when police officers have demonstrably failed to comply with statutory requirements.
• Justifiable grounds must be proven. The prosecution must specifically allege and prove any deviation from Section 21, and show that the integrity of the evidence was preserved despite the lapse.
• The burden is on the prosecution. Conviction must rest on the strength of the prosecution's evidence, not on the weakness of the defense.
