People v. Constantino
REITERATIONFacts
The Antecedents: On January 20, 2005, a buy-bust operation was conducted in Tuguegarao City based on a report that a certain "Jojit" was selling illegal drugs. A team was formed, with PO3 Domingo as the poseur-buyer. The team proceeded to Reynovilla St., Caritan Centro, where PO3 Domingo approached Constantino, identified himself as "Jojit," and asked for "stuff." After Constantino inquired how much was wanted, PO3 Domingo requested ₱1,000.00 worth of shabu and handed over the marked buy-bust money. Constantino then handed over two plastic sachets. PO3 Domingo gave the pre-arranged signal, and the team arrested Constantino, recovering the buy-bust money. The recovered drugs were marked "A-1" and "A-2" and submitted for laboratory examination, which confirmed the presence of methamphetamine hydrochloride. Constantino denied the charges, claiming he was framed and forced to hold the money by the police. Procedural History: The Regional Trial Court (RTC), Branch 5 of Tuguegarao City, found Constantino guilty of illegal sale of methamphetamine hydrochloride under Section 5, Article II of Republic Act No. 9165. The RTC rejected the defense's arguments regarding the alleged lack of detail in the operation, the police officers' lack of prior acquaintance with the accused, non-compliance with inventory and photograph requirements, failure to establish chain of custody, and lack of prior coordination with PDEA, holding that substantial compliance was met and omissions were directory. The RTC sentenced Constantino to life imprisonment and a fine of ₱500,000.00. Upon appeal, the Court of Appeals (CA) affirmed the RTC's decision in toto, finding the defense of frame-up uncorroborated and the chain of custody preserved. Constantino appealed to the Supreme Court. The Petition: Constantino contested his conviction, arguing inconsistencies in the prosecution witnesses' testimonies regarding the marking of the seized sachets, which he contended broke the chain of custody.
Issue(s)
Whether the prosecution sufficiently established the chain of custody of the seized dangerous drugs. Whether the guilt of the accused-appellant was proven beyond reasonable doubt.
Ruling
The Supreme Court granted the appeal, reversed and set aside the decision of the Court of Appeals, and acquitted the accused-appellant. The Court found that the prosecution failed to establish the chain of custody of the seized drugs due to glaring inconsistencies in the testimonies of the prosecution witnesses regarding who marked the plastic sachets, when, and where. This failure was deemed fatal to the prosecution's case, as it could no longer be assumed that the integrity and evidentiary value of the confiscated dangerous drug were properly preserved. Consequently, the accused-appellant was acquitted not because his defense of frame-up was given credence, but because the prosecution failed to discharge its burden of proving his guilt beyond reasonable doubt.
Ratio Decidendi
On the issue of whether the prosecution sufficiently established the chain of custody of the seized dangerous drugs: The Court found glaring inconsistencies in the testimonies of PO3 Domingo, PO3 Hernandez, and P/SInsp. Tulauan concerning the marking of the two plastic sachets of shabu. PO3 Domingo testified that SPO2 Tamang placed the marking "NBT" at the police station. PO3 Hernandez, however, stated that SPO2 Noel B. Taguiam placed the marking "NBT" after a few hours in their office. P/SInsp. Tulauan, the Forensic Chemist, declared that the marking "NBT" was made by SPO3 Nelson B. Tamaray, the duty officer who received the specimens at the crime laboratory. These conflicting accounts created doubt as to whether the sachets presented in court were the same ones confiscated from Constantino. The Court emphasized that the marking of the seized item immediately after seizure is the starting point in the custodial link and that a failure to mark at the time of initial custody imperils the integrity of the chain of custody. The prosecution's failure to present SPO2 Tamang or SPO2 Taguiam to validate the marking further diminished its importance as a reference point. This omission opened the door for suspicion that the shabu presented as evidence might have been planted or contaminated, thus breaking the chain of custody at a very early stage. On the issue of whether the guilt of the accused-appellant was proven beyond reasonable doubt: The Court reiterated that in prosecutions for illegal sale of dangerous drugs, the elements of the transaction, the delivery of the thing sold, and the presentation of the corpus delicti as evidence must be proven. Crucially, the identity and integrity of the seized drugs must be preserved from confiscation to presentation in court. While denial is a weak defense, the burden remains on the prosecution to overcome the presumption of innocence. In this case, the prosecution failed to establish the chain of custody, which is fatal to its case. The Court held that it could no longer consider or safely assume that the integrity and evidentiary value of the confiscated dangerous drug were properly preserved due to the broken chain of custody. Therefore, Constantino was acquitted not due to the credibility of his frame-up defense, but because the prosecution failed to meet the quantum of evidence required to prove his guilt beyond reasonable doubt.
Main Doctrine
The prosecution failed to establish the chain of custody of the seized drugs due to inconsistent testimonies regarding the marking of the sachets, leading to acquittal despite the presumption of regularity in the performance of official duties.
