In the Philippines, convictions for drug-related offenses hinge on the integrity of the evidence presented in court. The Supreme Court in People v. Jomar Castillo, emphasizes that the chain of custody for seized drugs must be meticulously maintained, with third-party witnesses present from the moment of seizure to ensure transparency and prevent tampering. Without this strict adherence, doubts arise, potentially leading to acquittal, as was the outcome in this case, highlighting the critical importance of procedural safeguards in drug cases.

Failing the Chain: How a Faulty Buy-Bust Led to Freedom

The case of People of the Philippines v. Jomar Castillo y Maranan began with accusations of illegal drug sale and possession against Castillo. The prosecution’s narrative centered on a buy-bust operation conducted by the Lipa City Police Station. Allegedly, after confirming tips about Castillo’s drug dealing, a buy-bust team was formed. The team claimed that a civilian asset purchased shabu from Castillo, who was then arrested and found to possess more of the substance. However, the subsequent handling of the seized drugs became the focal point of legal contention.

The defense challenged the prosecution’s case, arguing a failure to comply with the chain of custody requirements under Republic Act No. 9165, also known as the Comprehensive Dangerous Drugs Act of 2002. Central to this legal challenge was Section 21 of the Act, which outlines the procedure for handling seized drugs to ensure their integrity as evidence. This section mandates a strict protocol involving immediate inventory and photographing of the seized items in the presence of the accused, a media representative, a representative from the Department of Justice (DOJ), and an elected public official. The defense argued that the police officers deviated from this protocol, raising serious questions about the integrity of the evidence.

The Regional Trial Court initially found Castillo guilty, a decision that was later partially affirmed by the Court of Appeals. Both courts reasoned that the prosecution had sufficiently established the elements of the crimes charged, despite some procedural lapses. However, the Supreme Court took a different view, emphasizing the critical importance of adhering to the chain of custody rule. The Supreme Court examined the procedural lapses in the police’s handling of the seized drugs. The absence of required witnesses during the initial seizure and marking of the drugs, the Court argued, cast doubt on the origin and identity of the evidence. This doubt, according to the Supreme Court, was significant enough to warrant an acquittal.

To fully grasp the importance of the chain of custody, consider the words of the Supreme Court in Mallillin v. People:

Indeed, the likelihood of tampering, loss or mistake with respect to an exhibit is greatest when the exhibit is small and is one that has physical characteristics fungible in nature and similar in form to substances familiar to people in their daily lives. . . . A unique characteristic of narcotic substances is that they are not readily identifiable as in fact they are subject to scientific analysis to determine their composition and nature.

The Supreme Court underscored that marking the seized drugs immediately after confiscation is a vital step. This process is considered the starting point in the custodial link, acting as a reference for succeeding handlers of the specimens. The Court in People v. Saunar stated:

Crucial in proving the chain of custody is the marking of the seized drugs or other related items immediately after they have been seized from the accused. “Marking” means the placing by the apprehending officer or the poseur-buyer of his/her initials and signature on the items seized. Marking after seizure is the starting point in the custodial link; hence, it is vital that the seized contraband be immediately marked because succeeding handlers of the specimens will use the markings as reference. The marking of the evidence serves to separate the marked evidence from the corpus of all other similar or related evidence from the time they are seized from the accused until they are disposed of at the end of the criminal proceedings, thus, preventing switching, planting or contamination of evidence.

Building on this principle, the Court emphasized that the presence of third-party witnesses during the seizure and marking is not a mere formality. Their presence ensures the integrity of the seized items and prevents any opportunity for planting evidence. This point was driven home in People v. Tomawis:

The presence of the three witnesses must be secured not only during the inventory but more importantly at the time of the warrantless arrest. It is at this point in which the presence of the three witnesses is most needed, as it is their presence at the time of seizure and confiscation that would belie any doubt as to the source, identity, and integrity of the seized drug.

In Castillo’s case, the required third-party witnesses—a representative from the media, a representative from the DOJ, and an elected public official—were not present during the actual sale, arrest, search, seizure, and marking of the drugs. They were only called in later, at the police station, to witness the inventory and photographing of the seized items. This, according to the Supreme Court, defeated the purpose of having independent witnesses, as they had no personal knowledge of the events leading to the seizure. By excluding third-party witnesses at this stage, it opened the door to questions regarding the authenticity of the evidence presented against Castillo.

The prosecution, however, failed to provide any justifiable reason for the deviation from the prescribed procedure. The Supreme Court found that the prosecution’s sweeping assurances of compliance and integrity were insufficient to overcome the doubts raised by the procedural lapses. In essence, the prosecution did not convincingly argue why the buy-bust team failed to follow the strictures of Section 21. This failure ultimately led to the acquittal of Castillo, underscoring the principle that the prosecution must prove its case beyond a reasonable doubt, which includes demonstrating compliance with the chain of custody requirements.

The ruling in People v. Castillo serves as a reminder of the importance of adhering to proper procedures in drug-related cases. It reinforces the need for transparency and accountability in law enforcement, ensuring that the rights of the accused are protected. The strict application of the chain of custody rule, as emphasized by the Supreme Court, is a crucial safeguard against abuse and the potential for wrongful convictions. This ruling underscores that the prosecution must convincingly demonstrate that the integrity of the seized drugs was properly preserved throughout the entire process, from seizure to presentation in court. Failing this, the accused is entitled to an acquittal.
