In People v. Analyn Advincula, the Supreme Court acquitted the accused due to the prosecution’s failure to establish an unbroken chain of custody for the seized drugs. This ruling reinforces the critical importance of adhering to stringent procedural safeguards in drug-related cases. It underscores the necessity for law enforcement to meticulously document and preserve the integrity of drug evidence from the moment of seizure to its presentation in court, ensuring that the rights of the accused are protected and the reliability of the evidence is beyond doubt.

Cracks in the Chain: When Drug Evidence Fails to Convict

The case revolves around Analyn Advincula’s conviction for selling 0.008 grams of shabu during a buy-bust operation. The Court of Appeals affirmed the trial court’s guilty verdict, but the Supreme Court reversed this decision, focusing on the prosecution’s failure to adequately demonstrate an unbroken chain of custody for the seized drugs. This failure raised significant doubts about the integrity and authenticity of the evidence presented against Advincula.

At the heart of this case lies the legal principle of chain of custody, which is vital in drug-related prosecutions. The **chain of custody** refers to the documented sequence of possession and handling of evidence, particularly from the moment of seizure to its presentation in court. This ensures that the evidence presented is the same as that recovered from the accused, without any tampering or substitution. The importance of maintaining a clear and unbroken chain is to preserve the integrity and evidentiary value of the seized drugs.

The Supreme Court emphasized that even when the illegal sale of drugs is proven, the prosecution still bears the burden of proving the integrity of the corpus delicti, or the body of the crime. This means the prosecution must establish with moral certainty that the drugs sold by the accused are the same drugs examined in the laboratory and presented in court. Failure to do so creates reasonable doubt and warrants acquittal. According to the Court, this requirement removes unnecessary doubts concerning the identity of the evidence.

To guarantee the integrity of the evidence, the prosecution must comply with the chain of custody requirements. The Dangerous Drug Board (DDB) Regulation No. 1, Series of 2002, defines **chain of custody** as:

b. “Chain of Custody” means the duly recorded authorized movements and custody of seized drugs or controlled chemicals or plant sources of dangerous drugs or laboratory equipment of each stage, from the time of seizure/confiscation to receipt in the forensic laboratory to safekeeping to presentation in court for destruction. Such record of movements and custody of seized item shall include the identity and signature of the person who held temporary custody of the seized item, the date and time when such transfer of custody were made in the course of safekeeping and used in court as evidence, and the final disposition.”

The Supreme Court in *People v. Kamad* outlined the essential links in the chain of custody:

[F]irst, the seizure and marking, if practicable, of the illegal drug recovered from the accused by the apprehending officer; second, the turnover of the illegal drug seized by the apprehending officer to the investigating officer; third, the turnover by the investigating officer of the illegal drug to the forensic chemist for laboratory examination; and fourth, the turnover and submission of the marked illegal drug seized from the forensic chemist to the court.

In Advincula’s case, the Court found a critical missing link in the chain of custody. While PO2 Caballero, the poseur-buyer, testified about seizing and marking the drug and turning it over to the investigating officer, the prosecution failed to establish how the specimen came into the possession of PSI Johnny Gaspar, who delivered it to the crime laboratory. Neither the investigating officer, PO2 Ireneo Salazar, nor PSI Gaspar testified, leaving a gap in the chain of custody. This lack of personal knowledge regarding the handling of the seized drug, the court reasoned, made the evidence presented insufficient.

Moreover, the buy-bust team’s actions deviated from the procedure outlined in Section 21, Article II of R.A. No. 9165, the Comprehensive Dangerous Drugs Act of 2002. This section requires the apprehending team to conduct a physical inventory and photograph the seized drugs immediately after seizure and confiscation in the presence of the accused, a representative from the media, the Department of Justice (DOJ), and any elected public official. PO2 Caballero admitted that there was no photograph and inventory of the seized items, and no representatives from the DOJ, the media, or any elected public official were present during the marking of the shabu.

The Court underscored that these procedural safeguards are designed to prevent the pernicious practice of planting evidence, which has plagued drug-related cases in the past. The absence of these safeguards casts doubt on the integrity and credibility of the seizure and confiscation, ultimately affecting the trustworthiness of the evidence against the accused. Section 21(a), Article II of the Implementing Rules and Regulations (IRR) of R.A. No. 9165, provides an exception for non-compliance with these requirements, but only if there are justifiable grounds for the non-compliance and the integrity and evidentiary value of the seized items are properly preserved. However, the prosecution failed to provide any justification for the buy-bust team’s failure to comply with the required procedure.

Given these lapses and the broken chain of custody, the Supreme Court concluded that there was serious doubt about the integrity of the corpus delicti. This constituted a fatal procedural flaw, undermining the reliability of the evidence. The Court emphasized that it could not presume the police officers performed their duties regularly, as the records raised doubts about the regularity of their actions. Ultimately, the prosecution failed to overcome the presumption of innocence in favor of the accused, leading to her acquittal.
