G.R. No. 233653 - People vs. Guanzon y Ceneta

Case Summary (G.R. No. 233653)

Factual Background

On July 28, 2003, officers of the Philippine National Police, Antipolo City, received information that the accused was selling dangerous drugs at an address in Brgy. Mambugan, Antipolo City. The police coordinated with the Philippine Drug Enforcement Agency and executed a buy-bust operation. The buy-bust team included SPO2 Gerry S. Abalos as team leader, PO2 Vandever D. Hernandez as poseur-buyer, and members PO3 Cesar F. Paulos and PO3 Sherwin G. Bulan. The poseur-buyer gave marked money and allegedly received a small heat-sealed plastic sachet containing a white crystalline substance. The pre-arranged signal was given, the team effected the arrest, and a frisk of the accused allegedly produced another plastic sachet and the marked money. The sachet obtained by the poseur-buyer was marked as specimen “A”, and the sachet allegedly recovered from the accused was marked as specimen “B”. Both specimens were submitted to the PNP Crime Laboratory, which issued a chemistry report dated July 28, 2003, indicating positive tests for methamphetamine hydrochloride.

Defense Version

The accused maintained that he was arrested at a friend’s house by armed men who searched him and took his money and personal items. The defense asserted that the police, failing to recover dangerous drugs from the accused, used an asset to buy shabu to frame the accused, and thereafter concocted the narrative of a buy-bust arrest. The defense challenged the integrity of the seizure, the chain of custody, and the absence of required inventory and photographic documentation.

Charges and Trial Proceedings

The accused was charged in two Informations with illegal sale and illegal possession of dangerous drugs under Sections 5 and 11, Article II of R.A. No. 9165. Upon arraignment he pleaded not guilty. After pretrial and trial, the Regional Trial Court, Branch 73, Antipolo City, rendered a Decision on February 18, 2016 finding the accused guilty beyond reasonable doubt of illegal sale and illegal possession. The court sentenced him to life imprisonment and a fine of Five Hundred Thousand pesos for the illegal sale charge, and to imprisonment of twelve years and one day to twenty years and a fine of Three Hundred Thousand pesos for the illegal possession charge. The contraband were ordered confiscated and disposed of according to law.

Court of Appeals Ruling and Appeal to the Supreme Court

The accused appealed to the Court of Appeals. In a Decision dated May 31, 2017, the Court of Appeals affirmed the RTC Decision in toto, finding that the inconsistencies pointed out by the accused were minor and peripheral and that the totality of testimonial and documentary evidence established an unbroken chain of custody. The accused then brought the case to the Supreme Court, raising the alleged non-compliance with Section 21 of R.A. No. 9165 and its IRR as the principal ground.

Issue Presented

The sole issue before the Supreme Court was whether the RTC and the Court of Appeals erred in sustaining the conviction despite the alleged non-compliance with the mandatory requirements for custody and disposition of seized dangerous drugs under Section 21 of R.A. No. 9165, as amended by R.A. No. 10640, and its IRR.

Legal Standards Governing Conviction and Chain of Custody

The Court articulated the elements that the prosecution must establish to sustain convictions under R.A. No. 9165: for illegal sale under Section 5, the identity of buyer and seller, the object and consideration, and the delivery and payment; for illegal possession under Section 11, the possession of an item identified as a prohibited drug, lack of legal authorization, and the accused’s conscious awareness of possession (citing People v. Opiana, 750 Phil. 140 (2015); People v. Dela Cruz, 744 Phil. 816 (2014)). The Court reiterated that the corpus delicti in drug cases is the drug itself and that the State must prove the identity and integrity of the seized drug beyond reasonable doubt (citing Rontos v. People, 710 Phil. 328 (2013); People v. Relata, 679 Phil. 268 (2012)). The Court reproduced and relied on the text of Section 21 and the amended IRR, which require prompt marking, inventory, and photographing of seized items in the presence of the accused or representative, an elected public official and a representative of the National Prosecution Service or the media, and which recognize a narrow exception where noncompliance may be excused only upon justifiable grounds so long as integrity and evidentiary value were properly preserved.

Court’s Analysis of the Evidence and Chain of Custody

The Supreme Court found the appeal meritorious because the prosecution failed to establish an unbroken chain of custody. The Court examined testimonial evidence and identified material inconsistencies. PO3 Cesar F. Paulos testified that he recovered the sachet from the accused and turned it over to the team leader, SPO2 Abalos, who then had possession up to the police station. SPO2 Abalos, however, testified that Paulos had possession of the seized sachet from the area of arrest up to the police station. The contradiction created a gap in the second link of the chain. As to the bought drug, the Court observed that no witness clearly testified to its transfer from the accused to PO2 Hernandez and thereafter to subsequent handlers; PO2 Hernandez did not testify as to the handling of the bought drug after the arrest. The Court further noted that the marking of the specimens was not properly established; SPO2 Abalos stated only that he was beside PO2 Hernandez when the specimens were marked, and that the specimens were marked “A” and “B”, but he did not explain where the marking occurred and the accused was not present during the marking. The chemistry witness, PSI Angel C. Timario, testified that the specimens were pre-marked upon submission to the laboratory but identified the marking only as having been done by the “arresting officers.” The Court emphasized that marking is the first essential link in the chain of custody because it operates to set the seized items apart and to guard against switching, planting, or contamination (citing People v. Alberto Gonzales y Santos, 708 Phil. 121 (2013); People v. Rafols, 787 Phil. 466 (2016)). The Court held that the prosecution’s documentary evidence — the request for laboratory examination, initial laboratory report, chemistry report, certification, and a Sinumpaang Salaysay signed by Paulos and Abalos — did not cure the testimonial gaps because those documents failed to identify each custodian and to describe the manner and times of transfer. The Court relied on its prior holdings, including People v. Gener Villar y Poja, 799 Phil. 378 (2016), and People v. Pablo Arposeple y Sanchez, G.R. No. 205787, November 22, 2017, to underscore that where the first links are weak or broken the succeeding links fail an
