In the Philippines, an accused person is presumed innocent until proven guilty beyond a reasonable doubt. This principle is especially crucial in drug-related cases, where the prosecution must establish the identity and integrity of the seized substance to secure a conviction. The Supreme Court acquitted Wilson Suan y Jolongon because the prosecution failed to prove the identity of the substance allegedly seized from him and demonstrate an unbroken chain of custody. This means that if there’s any doubt that the drug presented in court is the same one taken from the accused, the case falls apart.

Did the Prosecution Drop the Ball? A Close Look at Evidence Handling in Drug Cases

The case of People of the Philippines vs. Wilson Suan y Jolongon (G.R. No. 184546, February 22, 2010) centers around the arrest and conviction of Wilson Suan for violating Section 11, Article II of Republic Act No. 9165, also known as the Comprehensive Dangerous Drugs Act of 2002. Suan was apprehended during a buy-bust operation, where police officers allegedly purchased shabu (methamphetamine hydrochloride) from him. The Regional Trial Court (RTC) found him guilty, and the Court of Appeals (CA) affirmed this decision. However, the Supreme Court took a closer look at the evidence and found critical flaws in the prosecution’s case.

The Supreme Court emphasized that in drug cases, the narcotic substance itself is the corpus delicti, or the body of the crime. This means that the prosecution must prove beyond a reasonable doubt that the substance seized from the accused is indeed a prohibited drug. As the court stated:

In prosecutions involving narcotics, the narcotic substance itself constitutes the corpus delicti of the offense and the fact of its existence is vital to sustain a judgment of conviction beyond reasonable doubt. The identity of the narcotic substance must therefore be established beyond reasonable doubt.

One of the major issues in Suan’s case was the identification of the shabu. The Certificate of Inventory prepared by the police officer merely stated that a sachet of a substance weighing 0.01 gram was seized, without any specific markings for identification. However, the Request for Laboratory Examination referred to the item as “Exhibit A,” and a subsequent memorandum indicated that the item already had markings. This discrepancy raised serious doubts about whether the substance examined in the laboratory was the same one seized from Suan.

Furthermore, there were inconsistencies in the weight of the substance. The Certificate of Inventory and other documents indicated a weight of 0.01 gram, while the Chemistry Report stated 0.1 gram. This tenfold difference further undermined the prosecution’s claim that the substance tested was the same one taken from the appellant. The Supreme Court found this discrepancy to be significant, noting that:

Indeed there is absolutely nothing in the evidence on record that tends to show identification of the drug. For sure, the difference particularly in the weight of the substance is fatal to the case of the prosecution.

Building on this point, the Court also highlighted the prosecution’s failure to establish an unbroken chain of custody. The chain of custody refers to the sequence of transfers and handling of the evidence, from the moment it is seized until it is presented in court. Each person who handles the evidence must be accounted for, and any break in this chain can cast doubt on the integrity of the evidence.

In Suan’s case, the police officer’s testimony was inconsistent regarding who received the substance after it was seized. He initially stated that it was delivered to the crime laboratory, but later claimed it was turned over to his team leader. The prosecution failed to present the team leader or any representative from the crime laboratory to testify about the handling of the substance. Without this testimony, there was a missing link in the chain of custody. The Court explained the importance of this unbroken chain:

There is obviously a missing link from the point when the drug was in his hands to the point when the same was submitted for examination. The failure to establish the evidence’s chain of custody is fatal to the prosecution’s case. Under no circumstance can we consider or even safely assume that the integrity and evidentiary value of the drug was properly preserved by the apprehending officers. There can be no crime of illegal possession of a prohibited drug when nagging doubts persist on whether the item confiscated was the same specimen examined and established to be the prohibited drug.

The standard operating procedure for handling seized drugs is outlined in Section 21, Article II of RA 9165 and its Implementing Rules and Regulations. This section requires a specific process for the seizure, custody, and handling of drug evidence to ensure its integrity and admissibility in court. The procedure includes immediate marking of the seized items, preparation of an inventory, and photographing the evidence in the presence of the accused or their representative. In the absence of these, it’s hard to know if the same items were sent and analyzed.

Because the prosecution failed to properly identify the substance and establish an unbroken chain of custody, the Supreme Court ruled that the presumption of innocence in favor of Suan had not been overcome. The Court reversed the decisions of the lower courts and acquitted Suan, stating:

Based on these findings and following our precedents in the afore-mentioned cases, we are compelled to reverse the judgment of conviction in this case. Consequently, we need not pass upon the merits of appellant’s defense of denial and frame-up. It is a well-entrenched rule in criminal law that the conviction of an accused must be based on the strength of the prosecution’s evidence and not on the weakness or absence of evidence of the defense.

This ruling underscores the critical importance of following proper procedures in drug cases. The prosecution must meticulously document and preserve the evidence to ensure its integrity and admissibility in court. Any failure to do so can result in the acquittal of the accused, regardless of the other circumstances of the case. This is because the burden of proof lies with the prosecution to prove guilt beyond a reasonable doubt, and any doubt must be resolved in favor of the accused.

Several other cases have followed similar reasoning. In People v. Mapa (G.R. No. 91014, March 31, 1993), the Supreme Court acquitted the appellant after the prosecution failed to clarify whether the specimen submitted for laboratory examination was the same one allegedly taken from the appellant. Similarly, in People v. Dimuske (G.R. No. 108453, July 11, 1994), the Court ruled that the failure to prove that the specimen of marijuana examined by the forensic chemist was that seized from the accused was fatal to the prosecution’s case. These cases highlight the consistent emphasis on proper handling and identification of drug evidence.
