In the case of Lito Lopez v. People of the Philippines, the Supreme Court overturned the conviction of Lito Lopez for illegal possession of dangerous drugs, emphasizing the critical importance of maintaining an unbroken chain of custody for drug evidence. The Court found that the prosecution failed to establish that the integrity and identity of the seized drugs were preserved, due to irregularities in marking and handling the evidence. This decision reinforces the need for law enforcement to strictly adhere to chain of custody procedures, protecting individuals from wrongful convictions and ensuring the reliability of evidence in drug-related cases.

Broken Links: How a Faulty Drug Evidence Chain Led to an Acquittal

The case began on July 31, 2000, when police officers, armed with a search warrant, raided Lito Lopez’s residence in Tabaco, Albay. During the search, they allegedly found small packets of shabu (methamphetamine hydrochloride) and drug paraphernalia. Lopez was subsequently charged with violating Section 16, Article III of Republic Act No. 6425, for illegal possession of dangerous drugs. After pleading not guilty, the trial court convicted Lopez, a decision that was later affirmed by the Court of Appeals. However, Lopez appealed to the Supreme Court, arguing that the identity and integrity of the seized items were not proven beyond reasonable doubt due to a flawed chain of custody.

At the heart of this case is the chain of custody rule, a critical component in drug-related prosecutions. The Supreme Court has consistently emphasized that the chain of custody must be meticulously maintained to ensure the integrity and identity of the seized drugs. This is because illegal drugs have unique characteristics that make them susceptible to tampering, alteration, or substitution. As the Court stated:

In both cases of illegal sale and illegal possession of dangerous drugs, the prosecution must show the chain of custody over the dangerous drug in order to establish the corpus delicti, which is the dangerous drug itself.

The chain of custody refers to the sequence of transfers and handling of evidence, from the moment of seizure to its presentation in court. Each person who comes into contact with the evidence must be accounted for, and any break in this chain can raise doubts about the authenticity of the evidence. The process begins with the marking of the seized items, which should be done immediately upon confiscation and in the presence of the accused.

In Lopez’s case, the prosecution’s evidence faltered at this crucial first step. According to the testimony, the seized items were marked at the police station, not at Lopez’s house during the search. This delay raised questions about whether the items presented in court were the same ones seized from Lopez. Moreover, there was conflicting testimony about who actually marked the items. PO3 Telado testified that the markings were done at the police station, surmising that PO3 Desuasido was responsible, but PO3 Desuasido was never questioned about the markings during the trial. This failure to properly document the initial marking of the evidence created a significant gap in the chain of custody.

The Supreme Court noted that:

The rule requires that the marking of the seized items should be done in the presence of the apprehended violator and immediately upon confiscation to ensure that they are the same items that enter the chain and are eventually the ones offered in evidence.

Furthermore, the Court emphasized that:

Marking after seizure is the starting point in the custodial link, thus it is vital that the seized contraband is 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 at the end of criminal proceedings, obviating switching, “planting,” or contamination of evidence.

The Court also pointed to other inconsistencies in the prosecution’s case. The Chemistry Report, which described the seized items, failed to mention any markings. During the trial, PO3 Desuasido struggled to identify the plastic sachets he claimed to have seized from Lopez’s house. PO3 Telado, on the other hand, identified the plastic sachets based solely on their size, and the aluminum foils based on their crumpled and folded condition. These vague identifications further undermined the prosecution’s claim that the evidence presented in court was the same as that seized during the search.

The Court emphasized that the unique nature of illegal drugs demands strict compliance with procedures for seizure, custody, and examination. The conflicting testimonies of the police officers and the lack of concrete evidence regarding the markings led the Court to conclude that no markings were actually made on the seized items. The absence of photographs taken after the seizure, which the prosecution witnesses claimed existed, further weakened their case.

In light of these deficiencies, the Supreme Court held that the prosecution had failed to establish an unbroken chain of custody. The Court cited the case of People v. Kamad, which outlined the links that must be established in a chain of custody:

1. The seizure and marking of the illegal drug by the apprehending officer.
2. The turnover of the illegal drug to the investigating officer.
3. The turnover by the investigating officer to the forensic chemist.
4. The turnover and submission of the marked illegal drug from the forensic chemist to the court.

The Court found substantial gaps in this chain, from the initial lack of markings to the unclear handling of the drugs during transit and at the police station. The Court highlighted the conflicting accounts of which police officer had custody of the drugs immediately after confiscation, and who transported them to the crime laboratory. Moreover, the records lacked details about who possessed the seized items after their chemical examination and before their presentation in court. These gaps raised significant doubts about the integrity of the evidence, leading the Court to acquit Lopez on reasonable doubt.

The Supreme Court emphasized the importance of these procedures, stating:

We have consistently held that failure of the authorities to immediately mark the seized drugs raises reasonable doubt on the authenticity of the corpus delicti and suffices to rebut the presumption of regularity in the performance of official duties. Failure to mark the drugs immediately after they were seized from the accused casts doubt on the prosecution evidence, warranting acquittal on reasonable doubt.
