In a significant ruling, the Supreme Court acquitted Fatima Tumangong of drug charges due to the prosecution’s failure to establish an unbroken chain of custody for the seized drugs. This decision underscores the critical importance of adhering to strict procedural safeguards in drug-related cases to protect individual rights and ensure the integrity of evidence. It serves as a reminder that law enforcement must meticulously follow protocols for handling and preserving evidence to secure a conviction.

When Evidence Vanishes: Can Broken Chains Lead to Freedom?

The case of People of the Philippines vs. Fatima Tumangong began when Fatima Tumangong was accused of selling 0.30 grams of methamphetamine hydrochloride, commonly known as “shabu,” during a buy-bust operation. The prosecution presented testimonies from police officers involved in the operation, asserting that Tumangong sold the illegal drugs to a poseur-buyer. However, the defense argued that the prosecution failed to properly establish the chain of custody of the seized drugs, raising doubts about the integrity of the evidence. The central legal question was whether the prosecution adequately proved that the seized drugs presented in court were the same drugs allegedly seized from Tumangong, and whether the procedural requirements for handling such evidence were strictly followed.

The Supreme Court emphasized that in cases involving illegal drugs, establishing an unbroken **chain of custody** is crucial. This chain ensures the integrity and evidentiary value of the seized items, preventing any tampering, substitution, or alteration from the moment of confiscation to its presentation in court. The Court outlined the four essential links in the chain of custody:

1. Seizure and marking of the illegal drug by the apprehending officer.
2. Turnover of the seized drug from the apprehending officer to the investigating officer.
3. Turnover of the drug by the investigating officer to the forensic chemist for examination.
4. Turnover and submission of the drug from the forensic chemist to the court.

The prosecution bears the burden of demonstrating each link in this chain. Failure to do so can raise reasonable doubt and potentially lead to acquittal. The Court referenced People v. Bartolini, stating the prosecution must show “every link in the chain, from the moment the dangerous drug was seized from the accused until the time it is offered in court as evidence.” This high standard reflects the Court’s concern for protecting individual rights against potential abuse or mishandling of evidence.

In Tumangong’s case, the Supreme Court found significant gaps in the chain of custody. While PO3 Briones, the arresting officer, testified about seizing and marking the drugs, the prosecution failed to present PO2 Saez, the investigating officer, and PO2 Manuel, who allegedly received the drugs at the crime laboratory. This omission raised serious questions about the handling and preservation of the evidence during critical stages. The Court cited People v. Hementiza, which stresses that “every person who touched the item must describe his or her receipt thereof, what transpired while the same was in his or her possession, and its condition when delivered to the next link.” The absence of testimony from PO2 Saez and PO2 Manuel created a critical break in the chain, undermining the prosecution’s case.

Furthermore, the Court noted that the police officers failed to comply with Section 21 of RA 9165, which requires that the seized item be photographed and inventoried in the presence of the accused, an elected public official, and representatives from the DOJ and the media. This requirement aims to ensure transparency and prevent the planting of evidence, a serious concern in drug-related cases. PO3 Briones’ explanation that he lacked a camera and the absence of a media representative or a DOJ representative raised further doubts about the integrity of the operation. While strict compliance may not always be possible, the Court emphasized that the police must provide justifiable reasons for any non-compliance. In this case, the lack of valid justification further weakened the prosecution’s position.

The Court also referenced People v. De Guzman y Danzil, stating that “the failure to observe the proper procedure negates the operation of the presumption of regularity accorded to police officers.” The presumption of regularity, which assumes that law enforcement officers perform their duties properly, can be overturned when there is clear evidence of procedural lapses or violations. In Tumangong’s case, the significant breaches of procedure committed by the police officers effectively destroyed this presumption, making it difficult to accept their testimonies at face value. Therefore, the Supreme Court stressed that courts should exercise a higher level of scrutiny when dealing with minuscule amounts of dangerous drugs as stated in People v. Caiz, emphasizing that stricter compliance with the rule on the chain of custody is necessary to prevent tampering.

In acquitting Fatima Tumangong, the Supreme Court reaffirmed its commitment to protecting individual rights and ensuring due process in drug-related cases. This decision serves as a reminder to law enforcement agencies about the importance of meticulous adherence to procedural safeguards and the need for transparency in handling evidence. The Court’s ruling emphasizes that failure to comply with the chain of custody requirements can have severe consequences, potentially leading to the dismissal of charges and the acquittal of the accused.
