In People v. Sipin, the Supreme Court acquitted the accused due to the prosecution’s failure to establish an unbroken chain of custody for seized drugs, highlighting the critical importance of maintaining the integrity of evidence in drug-related cases. This means that if the police cannot clearly show how the drugs were handled from the moment they were seized until they were presented in court, the accused cannot be convicted. This ruling reinforces the need for law enforcement to strictly adhere to procedural safeguards to protect individual rights and prevent wrongful convictions.

When Testimony Conflicts, Does Doubt Tip the Scales of Justice?

The case of People of the Philippines v. Vicente Sipin y De Castro revolves around the arrest and subsequent conviction of Vicente Sipin for the illegal sale and possession of dangerous drugs. The prosecution presented evidence from a buy-bust operation where Sipin allegedly sold 0.02 grams of shabu to a poseur-buyer. During the arrest, another 0.02 grams of shabu were found in his possession. The central legal question is whether the prosecution adequately proved the chain of custody of the seized drugs, a critical requirement under Philippine law to ensure the integrity of the evidence and prevent tampering.

The facts presented by the prosecution hinged on the testimonies of several police officers involved in the buy-bust operation. According to their account, a confidential informant tipped off the Binangonan Police Station about a certain “Enteng” selling shabu. A buy-bust team was formed, and PO1 Richard Raagas acted as the poseur-buyer, purchasing shabu from Enteng, later identified as Vicente Sipin. PO1 Arnel Diocena arrested Sipin after the transaction, and PO1 Dennis Gorospe served as back-up and investigating officer. The police officers testified that the seized drugs were marked, inventoried, and sent to the crime laboratory for examination, where they tested positive for methylamphetamine hydrochloride, commonly known as shabu.

In contrast, Sipin testified that he was framed. He claimed that he was approached by a police asset named Rolly, who asked him to cooperate in identifying a notorious group in the area. When Sipin refused, Rolly allegedly threatened him. Shortly after, Sipin was apprehended by police officers and forced to admit possession of shabu. The defense argued that the police officers failed to properly establish the chain of custody of the seized drugs, raising doubts about the integrity of the evidence.

The Regional Trial Court (RTC) found Sipin guilty beyond reasonable doubt, relying heavily on the testimonies of the police officers and the presumption of regularity in the performance of their official duties. However, the Court of Appeals (CA) affirmed the RTC’s decision, agreeing that the integrity of the seized items was duly preserved because the prosecution presented key witnesses who established the chain of custody from confiscation to examination. Dissatisfied, Sipin appealed to the Supreme Court, arguing that the prosecution failed to establish an unbroken chain of custody and that the testimonies of the police officers were inconsistent.

The Supreme Court emphasized that in drug-related cases, the corpus delicti, or the body of the crime, is the dangerous drug itself. Therefore, it is crucial to prove beyond reasonable doubt that the seized item is the same object tested and presented in court as evidence. This is achieved through establishing an unbroken chain of custody, which involves identifying each person who handled the evidence, from seizure to presentation in court. The links in this chain include: (1) seizure and marking of the drug by the apprehending officer; (2) turnover of the drug to the investigating officer; (3) turnover by the investigating officer to the forensic chemist; and (4) submission of the drug from the forensic chemist to the court.

In analyzing the evidence, the Supreme Court found significant inconsistencies in the testimonies of the police officers that cast doubt on the chain of custody. For instance, there were conflicting accounts of who handed the specimens to PO1 Diocena for delivery to the crime laboratory. PO1 Gorospe testified that he gave the specimen to PO1 Diocena, while PO1 Diocena stated that PO1 Raagas handed it to him. This discrepancy raised questions about the integrity of the transfer process.

The inconsistencies did not end there. There was also a dispute over who confiscated the second sachet of shabu found in Sipin’s possession. PO1 Diocena claimed he confiscated it and gave it to PO1 Raagas, while PO1 Raagas stated he recovered both sachets from Sipin himself. Furthermore, the officers disagreed on whether there was a commotion during the arrest, which would have prevented the proper inventory and photographing of the evidence. PO1 Gorospe insisted there was a commotion, while PO1 Raagas claimed no one else was present. Adding to the confusion, PO1 Diocena testified that the seized items were placed in a stapled plastic container, while PO1 Raagas said they were wrapped in a bond paper.

Moreover, the Supreme Court noted that the prosecution failed to present the inventory of the seized items as evidence, and the police officers gave conflicting accounts of whether an inventory was even made. These inconsistencies, taken together, created reasonable doubt about the integrity of the evidence and the reliability of the police officers’ testimonies. The Court also pointed out the police officers’ non-compliance with Section 21(1), Article II of R.A. No. 9165, which requires the apprehending team to immediately conduct a physical inventory and photograph the seized drugs in the presence of the accused, a representative from the media, a representative from the Department of Justice (DOJ), and any elected public official.

Sec. 21. Custody and Disposition of Confiscated, Seized, and/or Surrendered Dangerous Drugs, Plant Sources of Dangerous Drugs, Controlled Precursors and Essential Chemicals, Instruments/Paraphernalia and/or Laboratory Equipment. – The PDEA shall take charge and have custody of all dangerous drugs, plant sources of dangerous drugs, controlled precursors and essential chemicals, as well as instruments/paraphernalia and/or laboratory equipment so confiscated, seized and/or surrendered, for proper disposition in the following manner:

(1) The apprehending team having initial custody and control of the drugs shall, immediately after seizure and confiscation, physically inventory and photograph the same in the presence of the accused or the person/s from whom such items were confiscated and/or seized, or his/her representative or counsel, a representative from the media and the Department of Justice (DOJ), and any elected public official who shall be required to sign the copies of the inventory and be given a copy thereof;

The Supreme Court emphasized that the prosecution bears the burden of proving a valid cause for non-compliance with this procedure. In this case, the prosecution failed to provide any justifiable reason why the police officers did not follow the required procedure or obtain the presence of the necessary witnesses. The Court rejected the invocation of the presumption of regularity in the performance of official duty, stating that the lapses in procedure themselves were affirmative proofs of irregularity. The Court reiterated that strict adherence to Section 21 is required, especially when the quantity of illegal drugs seized is minimal, as it is highly susceptible to planting, tampering, or alteration of evidence. Therefore, the Supreme Court held that the prosecution failed to establish beyond reasonable doubt the unbroken chain of custody of the drugs seized from Sipin, and, consequently, Sipin was acquitted.

If the chain of custody is broken, the integrity of the evidence is compromised, and it may be deemed inadmissible in court.
What are the requirements for a valid chain of custody under R.A. No. 9165?	Under R.A. No. 9165, the apprehending team must immediately conduct a physical inventory and photograph the seized drugs in the presence of the accused, a representative from the media, a representative from the Department of Justice (DOJ), and any elected public official. These witnesses must sign the inventory and be given a copy.
What happens if the police fail to comply with the chain of custody requirements?
