G.R. No. 243386 - People vs. De Castro y Santos

Case Summary (G.R. No. 243386)

Factual Background

The two Informations alleged that on 4 August 2010, in Muntinlupa City, De Castro, who was not authorized by law, committed (i) illegal possession of methamphetamine hydrochloride weighing 0.12 gram, placed in two small heat-sealed transparent plastic sachets inside a yellow plastic container; and (ii) illegal sale, trading, delivering, and giving away methamphetamine hydrochloride weighing 0.02 gram contained in one small heat-sealed transparent plastic sachet. Upon arraignment, De Castro pleaded not guilty to both charges.

Prosecution Version: Buy-Bust Operation and Arrest

The prosecution presented witnesses including PCI Richard Allan Mangalip (Forensic Chemist), PO3 Aires Abian (Evidence Custodian), NUP Bernardo Bucayan (Receiving Officer), and PO3 Manuel Amodia Jr. (Apprehending Officer), while the parties entered into stipulations that dispensed with the testimonies of certain witnesses. Based on the CA’s summary of the prosecution evidence, the buy-bust operation proceeded as follows: the police received a tip from an informant that De Castro was selling shabu for P300.00 and, after coordination steps were reportedly completed—including preparation of a Pre-Operational Report, Coordination Form, and Certificate of Coordination, submission to the PDEA under a stated Control Number, and preparation of buy-bust money consisting of genuine P100.00 bills—the team proceeded to a target site in Alabang, Muntinlupa City.

At the site, PO3 Amodia acted as poseur-buyer with the informant. De Castro allegedly approached them, the informant introduced Amodia as his cousin, and Amodia handed De Castro the marked buy-bust money. After De Castro allegedly pocketed and inserted the bills into his shorts, he supposedly withdrew a small yellow plastic container, opened it, took out a sachet of suspected shabu, and handed it to Amodia. Amodia then executed the pre-arranged signal, declared the transaction consummated, and after introducing himself as a policeman, seized the container and other sachets. The police also allegedly recovered the buy-bust money from De Castro, retrieved additional sachets from the container, arrested De Castro, and informed him of constitutional rights and the reason for arrest.

The prosecution further claimed that at the place of arrest and seizure, Amodia marked the container and sachets with identifying markings. To avoid commotion as people allegedly began to emerge, the police reportedly brought De Castro and the seized items to the police office for inventory and documentation. There, a Certificate of Inventory was prepared. The police stated that attempts to summon representatives from the media, the DOJ, and an elected public official were futile, and inventory proceeded without them. The police prepared booking documents and a Request for Laboratory Examination on Seized Evidence, which was signed by PINSP Diaz. The seized contraband was allegedly delivered to the Southern Police District (SPD) Crime Laboratory; the prosecution asserted that the seized contraband delivered was never altered and that the chain of custody was preserved. PCI Mangalip conducted laboratory examination and found the seized substance positive for methamphetamine hydrochloride, as evidenced by a stated physical science report.

Defense Version: Denial and Claim of Illegal Arrest

De Castro testified as the sole witness for the defense. He claimed he was an ice delivery truck driver who, on 3 August 2010 at around 7:00 p.m., parked his truck in Cas[t]ro, Alabang, Muntinlupa, when a white vehicle arrived and three men, later identified as policemen, grabbed and searched him. De Castro claimed that when the police failed to find anything, he was ordered to board their vehicle. He alleged that upon arrival at the CID office, police took names of the arrested persons including him, and later transferred him for detention.

De Castro further claimed that on 5 August 2010 at about 3:00 p.m., PO2 Hernaez brought him for inquest proceedings, after which police returned him to detention and later charged him with violations of Section 11 and Section 5 of RA 9165. He denied selling illegal drugs and asserted that the arrest occurred on 3 August 2010, not on 4 August 2010.

Trial Court and Appellate Rulings

The RTC, in a consolidated decision dated 16 November 2015, found De Castro guilty beyond reasonable doubt of both offenses. It held that the prosecution proved the elements of illegal sale and illegal possession and that the buy-bust operation was well documented, including the pre-operational documents, coordination with the PDEA, and the briefing and conduct of the operation. The RTC sustained the identification made by PO3 Amodia over De Castro’s denial and found substantial compliance with legal requirements on handling seized items. It ruled that the integrity and evidentiary value of the seized drugs were not diminished and that the chain of custody was not shown to be broken.

On appeal, the CA affirmed on 6 February 2018. It ruled that the elements of illegal possession and illegal sale were proven and that non-compliance with Section 21 of RA 9165 did not invalidate the seizure and custody as long as integrity and evidentiary value were preserved. The CA also found no showing that police officers deviated from their duties and applied the presumption of regularity.

Issue on Appeal

The Supreme Court framed the question as whether De Castro’s guilt for violation of Sections 5 and 11 of RA 9165 had been proven beyond reasonable doubt.

Legal Basis and Reasoning

The Supreme Court emphasized that in dangerous drugs prosecutions, the confiscated drug constitutes the corpus delicti, making the fact of its existence essential to conviction. It held that therefore the identity and integrity of the seized drugs must be established with moral certainty. The prosecution must show an unbroken chain of custody and must account for each link from seizure through presentation in court.

In this connection, the Court reiterated that Section 21, Article II of RA 9165 strictly requires that seized items be immediately inventoried and photographed after seizure or confiscation, and that physical inventory and photographing be done in the presence of four categories of witnesses: the accused (or representative or counsel), an elected public official, a media representative, and a DOJ representative. The Court acknowledged that strict compliance may not always be possible due to field conditions, but it held that non-compliance does not automatically void the seizure and custody. Still, the prosecution must prove (a) a justifiable ground for non-compliance and (b) that the integrity and evidentiary value of the seized items were preserved.

Applying those standards, the Court ruled that the buy-bust team blatantly disregarded Section 21 and lacked a valid excuse. Although the police allegedly marked the drugs at the place of arrest, they decided to bring the accused and evidence to their office for inventory after noticing people were coming out. The Court pointed out that the testimony of PO3 Amodia showed that none of the required witnesses was present at the time of arrest and seizure and likewise none was present during inventory at the police office. The police allegedly admitted they prepared the inventory in their office because they lacked the necessary documents and because people were coming out, and they stated they tried to call several persons but nobody arrived. The Court found that the team merely attempted to “call-in” the witnesses after the buy-bust operation had already been finished. The Court treated that practice as precisely what Section 21 was designed to prevent: the presence of witnesses is meant to insulate against planting and to prevent manipulation of seized evidence.

The Court also held that the explanation given—people coming out and absence of necessary documents at the arrest site—did not satisfy the prosecution’s burden. It underlined that the prosecution must allege and prove that attendance was impossible because of recognized circumstances such as remote area, threats to witness safety due to immediate retaliatory action, participation of an elected official in the punishable acts, proven futility of efforts without arresting officers’ fault, or time constraints tied to confidential tips. The Court found that none of those recognized circumstances was attendant. It further held that since buy-bust is a planned activity, it was strained to believe the police could not ensure the required witnesses’ presence.

Consequently, the Court ruled that the integrity of the corpus delicti was compromised,

Case Syllabus (G.R. No. 243386)

The case arose from an Appeal under Section 13(c), Rule 124 of the Rules of Court, from the Court of Appeals (CA) Decision dated February 6, 2018 in CA-G.R. CR-HC No. 07962.

The buy-bust was triggered by a tip that De Castro was selling shabu for P300.00, and it was treated as a planned law enforcement operation.
The police allegedly conducted pre-operation documentation, including a Pre-Operational Report, Coordination Form, and Certificate of Coordination brought to PDEA with Control Number PDEA-MMRO 0810-00029.
The buy-bust team allegedly prepared marked money consisting of three genuine P100.00 bills and recorded the operation in the logbook.

The Informant allegedly told De Castro they wanted to buy P300.00 worth of shabu, introduced PO3 Amodia to De Castro as the Informant’s cousin, and handed De Castro the buy-bust money.
After receiving the money, De Castro allegedly folded the bills and inserted them in his right waist pocket, then drew a small yellow plastic container from his left waist and handed a sachet containing a white crystalline substance to PO3 Amodia.
After the pre-arranged signal, PO3 Amodia allegedly introduced himself as a policeman and grabbed De Castro’s right hand, while backup frisking allegedly recovered the buy-bust money.
