In People v. Meriam Guru y Kazan, the Supreme Court acquitted the accused due to the prosecution’s failure to establish an unbroken chain of custody for seized drugs. This means that the prosecution did not sufficiently prove that the substance confiscated from the accused was the same substance presented in court as evidence. The ruling underscores the importance of meticulously following procedures for handling drug evidence, ensuring its integrity from seizure to presentation in court, and ultimately protecting individuals from wrongful convictions based on compromised evidence.

When Evidence Disappears: Questioning Drug Chain of Custody

Meriam Guru y Kazan faced charges for violating Sections 5 and 11(3) of Article II of Republic Act No. 9165, concerning the sale and possession of illegal drugs. The prosecution presented testimonies from PO1 Juaño and PO1 Bajarias, who described a buy-bust operation where Guru allegedly sold and possessed shabu. The key pieces of evidence were two sachets of white crystalline substance, marked as “MG” and “MGK,” which were purported to contain methylamphetamine hydrochloride, a dangerous drug. The defense, however, contested the integrity of the chain of custody of these drugs, raising doubts about whether the substances tested and presented in court were the same ones seized from Guru.

The Supreme Court’s analysis centered on whether the prosecution had sufficiently established the chain of custody, a critical aspect in drug-related cases. This concept ensures that the evidence presented in court is the same evidence seized from the accused, preventing contamination, alteration, or substitution. The Court emphasized that proving the identity and integrity of the corpus delicti—the body of the crime—is essential for a conviction. In this case, the prosecution needed to demonstrate a clear, unbroken trail of possession and handling of the drug specimens from the moment of seizure to their presentation in court. Failing to do so casts doubt on the reliability of the evidence.

The Court referred to the case of Malillin v. People, explaining the importance of establishing the chain of custody:

As a method of authenticating evidence, the chain of custody rule requires that the admission of an exhibit be preceded by evidence sufficient to support a finding that the matter in question is what the proponent claims it to be. It would include testimony about every link in the chain, from the moment the item was picked up to the time it is offered into evidence, in such a way that every person who touched the exhibit would describe how and from whom it was received, where it was and what happened to it while in the witness’ possession, the condition in which it was received and the condition in which it was delivered to the next link in the chain. These witnesses would then describe the precautions taken to ensure that there had been no change in the condition of the item and no opportunity for someone not in the chain to have possession of the same.

Inconsistencies and gaps in the evidence presented by the prosecution undermined their case. PO1 Juaño testified that an unnamed investigator marked the seized items at the police station. This lack of specificity raised concerns about the identity and competence of the person handling the evidence. Furthermore, the request for laboratory examination was prepared by Police Superintendent Ernesto Tubale Barlam, and delivered by PO2 Garcia, individuals not mentioned in the testimonies of PO1 Juaño and PO1 Bajarias. This discrepancy created a significant gap in accounting for the custody of the specimens.

The Court also cited Section 21 of Republic Act No. 9165, which outlines the procedure for handling confiscated drugs:

Section 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 Court noted that the required physical inventory of the drugs was not conducted immediately after seizure in the presence of the accused, but later at the police station. This deviation from the prescribed procedure, coupled with the other inconsistencies, raised serious doubts about the integrity of the evidence. While strict compliance with Section 21 may be relaxed under justifiable circumstances, the prosecution failed to demonstrate that the evidentiary value and integrity of the seized drugs were properly preserved. The court held that substantial gaps in the chain of custody created a rational uncertainty regarding the corpus delicti, warranting an acquittal based on reasonable doubt. The ruling underscores that even if a buy-bust operation appears legitimate, failure to meticulously document and preserve the chain of custody can invalidate the entire case.
