Safeguarding Rights: The Importance of Procedural Compliance in Drug Cases

The Supreme Court acquits a drug suspect due to broken chain of custody, emphasizing strict procedural compliance in drug cases.


The Supreme Court, in People v. Alboka (G.R. No. 212195, February 21, 2018), acquitted an accused convicted of illegal sale and possession of dangerous drugs. The acquittal was not because the accused was innocent, but because the prosecution failed to prove her guilt beyond reasonable doubt. The case underscores a vital principle in Philippine criminal law: in drug cases, the State must not only prove the crime but also strictly comply with procedural rules on handling seized evidence. When law enforcers break the chain of custody, the integrity of the evidence is compromised, and the accused must be acquitted.

The Facts of the Case

In December 2007, police operatives conducted a buy-bust operation against a certain "Bobby" in Muntinlupa City. The operation led to the arrest of Namraida Alboka, who allegedly sold shabu to a poseur-buyer and was found in possession of additional sachets of the same substance. She was charged with violation of Sections 5 and 11, Article II of Republic Act No. 9165, the Comprehensive Dangerous Drugs Act of 2002.

The Regional Trial Court convicted Alboka, and the Court of Appeals affirmed the conviction. The courts gave weight to the testimony of the police officers and applied the presumption of regularity in the performance of official duties. Alboka appealed to the Supreme Court.

The Issue Presented

The sole issue was whether the prosecution had proven Alboka's guilt beyond reasonable doubt. The Supreme Court examined the records and found that the lower courts had overlooked crucial facts regarding the handling of the seized drugs.

The Broken Chain of Custody

The Supreme Court reversed the conviction, ruling that the prosecution failed to establish an unbroken chain of custody of the seized drugs. The chain of custody rule requires that the prosecution account for the seized item from the moment of seizure to its presentation in court. This ensures that the drugs presented as evidence are the very same items seized from the accused.

The Court identified several fatal gaps in the chain:

First, the marking of the seized items. While the officer claimed he marked the sachets at the scene, the prosecution failed to elicit testimony on where and when the markings were made, and whether they were done in the presence of the accused. The joint affidavit of arrest was silent on this matter.

Second, the lack of inventory and photography. The police did not conduct a physical inventory of the seized items in the presence of the accused, a representative from the media, the Department of Justice, and an elected public official, as required by Section 21 of R.A. 9165. No photographs were taken. The prosecution offered no justifiable reason for these lapses.

Third, the unexplained turnover of the drugs. The apprehending officer turned over the seized items to an investigator but admitted he did not know where the investigator took them. The prosecution also failed to explain why the apprehending officers, rather than the investigator, brought the drugs to the crime laboratory.

Fourth, the unaccounted submission to court. The prosecution failed to show who brought the seized items to the trial court. The testimony of the forensic chemist was dispensed with through stipulations, leaving another gap in the chain.

The Presumption of Regularity Cannot Save the Prosecution

The Court acknowledged the presumption of regularity in the performance of official duties by police officers. However, this presumption can be overturned when evidence shows that the officers did not properly perform their duties. The serious gaps in the chain of custody demonstrated that the police officers failed to accurately perform their functions. The presumption of regularity, therefore, could not arise.

The Court stressed that the corpus delicti in drug cases is the dangerous drug itself. If its identity and integrity are compromised, the prosecution's case fails. The flagrant noncompliance with Section 21 of R.A. 9165 rendered the seizure and custody of the items void.

Practical Takeaways

  • Procedural compliance is mandatory. In drug cases, the prosecution must strictly comply with Section 21 of R.A. 9165, which requires inventory and photography of seized items in the presence of the accused, a media representative, a DOJ representative, and an elected public official.

  • The chain of custody must be unbroken. Every link in the chain—from seizure, marking, turnover to the investigator, submission to the forensic chemist, and presentation in court—must be established through clear testimony.

  • Marking must be immediate and in the presence of the accused. The marking of seized drugs should be done at the place of arrest, immediately upon confiscation, and in the presence of the accused.

  • Presumption of regularity is not automatic. It can be overturned when the prosecution fails to explain procedural lapses. The State must acknowledge and justify any deviation from the prescribed procedure.

  • The burden rests on the prosecution. The accused has no burden to prove innocence. If the prosecution fails to prove guilt beyond reasonable doubt, the accused must be acquitted, regardless of the weakness of the defense.
