Unlawful Arrest Invalidates Drug Possession Charges Protecting Constitutional Rights

The Supreme Court's decision in People v. Callejo y Tadeja (G.R. No. 227427, June 6, 2018) serves as a powerful reminder that law enforcement must follow procedure even when pursuing drug offenders. The Court acquitted two women convicted of drug sale and possession because police officers failed to comply with the mandatory requirements of Section 21 of Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002.

The ruling reinforces that the rights of the accused are not mere technicalities. When police violate the rules on seizure and custody of evidence, the prosecution's case collapses—no matter how serious the charge.

The Facts of the Case

On August 13, 2010, police officers from the Makati City Police Station conducted a buy-bust operation against Delia Callejo and Silvera Antoque. The officers claimed that Antoque offered shabu to the poseur-buyer, and Callejo handed over a plastic sachet after receiving the marked P500 bill. A second sachet was allegedly recovered from Callejo.

The Regional Trial Court convicted both women—Callejo for illegal sale and illegal possession of drugs, and Antoque for illegal sale. The Court of Appeals affirmed the conviction. The Supreme Court, however, reversed the decisions and acquitted the appellants.

The Issue Before the Court

The central question was whether the prosecution had proven the guilt of the accused beyond reasonable doubt, particularly whether the police complied with Section 21 of RA 9165 and whether the chain of custody of the seized drugs was unbroken.

The Ruling: Procedural Lapses Create Reasonable Doubt

The Supreme Court found that the police committed patent procedural lapses that created reasonable doubt as to the identity and integrity of the seized drugs.

Failure to Comply with the Three-Witness Rule

Section 21 requires that the physical inventory and photographing of seized drugs be conducted in the presence of the accused or their representative, a representative from the media, a representative from the Department of Justice, and any elected public official.

In this case, only Barangay Kagawad Bernal was present during the inventory. No media or DOJ representatives were secured. More importantly, Kagawad Bernal testified that he was at home cooking when the police called him—he did not witness the arrest or the seizure. He was summoned only to sign the inventory receipt.

The Court emphasized that the three witnesses must be present at the time of apprehension, not called in afterward. Since a buy-bust operation is a planned activity, the police had ample time to bring the witnesses to the intended place of arrest. The practice of calling witnesses only after the operation has finished defeats the purpose of the law: preventing the planting or contamination of evidence.

Broken Chain of Custody

The prosecution also failed to establish an unbroken chain of custody. While the parties stipulated on the existence of certain documents and the subject matter of testimonies of the investigator and forensic chemist, these stipulations did not cover how the seized items were handled, stored, and transferred between custodians.

Citing People v. Sanchez, the Court held that stipulations are confined to what was actually agreed upon. They do not excuse the prosecution from proving each link in the chain—from seizure, to the investigating officer, to the forensic laboratory, and finally to the court.

Inconsistent Testimonies

The Court also noted material inconsistencies in the police officers' testimonies regarding the confidential informant. The officers claimed the informant's identity was confidential, yet admitted that the informant was known to the accused and was present during the operation, openly assisting in the transaction. This contradiction undermined the credibility of the prosecution's narrative.

Why This Decision Matters

The ruling underscores that Section 21 is substantive law, not a mere procedural technicality. The Court quoted its earlier ruling that the campaign against illegal drugs, however noble, must be executed within the boundaries of law.

The presumption of regularity in the performance of official duties cannot save a prosecution when the police have clearly violated mandatory procedures. The Court refused to excuse the lapses through the expedience of invoking this presumption.

Practical Takeaways

• The three-witness rule is mandatory. Police must secure the presence of a media representative, a DOJ representative, and an elected public official at the time of arrest and seizure—not after the fact.
• Witnesses must have personal knowledge. A witness who merely signs an inventory receipt without witnessing the arrest or seizure does not satisfy the requirements of Section 21.
• Chain of custody must be fully established. Stipulations on documents do not automatically prove how seized items were handled, stored, and transferred. Every link must be accounted for.
• Presumption of regularity is not a shield. When police violate mandatory procedures, the presumption cannot cure the defects in the prosecution's case.
• For those accused of drug offenses, procedural violations matter. A conviction requires proof beyond reasonable doubt, and that includes proving compliance with Section 21.
