People of the Philippines vs. Allan Acdang y Balangen

In a prosecution for cultivation or culture of dangerous drugs under Section 16 of Republic Act No. 9165, proof beyond reasonable doubt requires an unbroken chain of custody over the seized plant source. Unjustified failure to comply with the inventory and photographing requirements—especially the absence of the mandatory insulating witnesses without proof of justifiable grounds and earnest efforts to procure them—creates reasonable doubt as to the identity and integrity of the corpus delicti and mandates acquittal.

Allan Acdang y Balangen and his brother Alfredo Acdang y Balangen were accused of violating Section 16 of Republic Act No. 9165 for allegedly cultivating marijuana in a plantation of around 5,000 square meters in Sitio Mocgao, Barangay Badeo, Kibungan, Benguet. The charge emerged from Oplan Farmville 3, a coordinated PDEA operation to destroy or uproot marijuana plantations in the tri-boundaries of La Union, Ilocos Sur, and Benguet. Because the seizure occurred on February 11, 2011, the governing chain-of-custody provision was Section 21 of Republic Act No. 9165 before its amendment by Republic Act No. 10640, which required three insulating witnesses during inventory and photographing: an elected public official, a Department of Justice representative, and a media representative.

On April 13, 2011, an Information was filed before the Regional Trial Court charging brothers Alfredo and Allan Acdang y Balangen with violation of Section 16 of Republic Act No. 9165. It alleged that, on February 11, 2011, in Sitio Mocgao, Barangay Badeo, Kibungan, Benguet, the two, conspiring and mutually aiding one another, willfully and unlawfully cultivated and planted marijuana in an area of about 5,000 square meters.

According to the prosecution, the PDEA-Cordillera Administrative Region and PDEA Regional Office 1 organized Oplan Farmville 3 to destroy or uproot marijuana plantation sites in the tri-boundaries of La Union, Ilocos Sur, and Benguet. Team Omega, whose members included Intelligence Officer 1 Nickson Q. Acosta, Atty. Allan D. Ancheta, Police Officer II Christian R. Boado, Agent Dexter Asayco, and Senior Police Officer IV Nicolas Luna, received a final briefing on February 9, 2011, then traveled to Sitio Mocgao. The team arrived at a first plantation at around 7:00 a.m. on February 10, 2011, found no one there, and withdrew. At about 7:00 a.m. on February 11, 2011, they returned and saw two men cleaning and weeding beds of marijuana seedlings from a distance of about ten meters. The team rushed forward and arrested the two, later identified as Allan and Alfredo. Agent Asayco arrested Alfredo, while SPO4 Luna arrested Allan. They were informed of the nature of their arrest and their constitutional rights, and PO2 Boado conducted a body search. Atty. Ancheta photographed the plants. IO1 Acosta uprooted 53 samples of marijuana seedlings from the first plantation, tied them with a red ribbon, and placed masking tape bearing his initials on the bundle; the rest of the plants were burned. The team then proceeded to a second plantation about 100 meters away, where IO1 Acosta uprooted 11 fully grown marijuana plants, tied them with a red ribbon, and attached masking tape bearing his initials, signature, and the date February 11, 2011. The remaining plants at the second site were burned. Inventories were prepared at the plantation sites, but no required insulating witness was present.

After the plants were burned, Allan and Alfredo asked Team Omega to be brought to their house so they could pack clothes and provisions. Their request was granted; after about 30 minutes of walking, Allan escaped. At Alfredo’s house, the officers saw in plain view a hydraulic jack, one marijuana molder, one weighing scale, and a sack of dried marijuana leaves weighing around 1.7 kilograms, and they confiscated these items. IO1 Acosta marked the items seized in the house with his initials “NQA,” the date, and his signature; a barangay official was present during that inventory. Team Omega, together with Alfredo, left Sitio Mocgao at 2:00 p.m. on February 11, 2011, proceeded to PDEA-Regional Office 1, and then went to Camp Dangwa. At 8:00 p.m. that day, IO1 Randy M. Tindaan received the confiscated items from IO1 Acosta, counted and itemized them, prepared a final inventory, and delivered the items with a written request for examination to Police Senior Inspector Rowena F. Canlas. PSINSP Canlas conducted physical, chemical, and confirmatory tests; the initial laboratory report issued that day showed the first eight specimens positive for marijuana, and the final chemistry report issued the following day showed the remaining specimens positive for marijuana.

The defense presented a different account. Allan denied the accusation and testified that at 3:00 a.m. on February 11, 2011, he and his brother Enero were asleep at their house when they heard knocking; upon opening the door, he saw Alfredo with 14 police officers in camouflage uniforms armed with guns. He and Enero were told to lie face down and were frisked, but the officers found nothing. At around 4:00 a.m., Allan and Alfredo were brought to two gardens, where they were ordered to uproot and burn marijuana while officers took pictures. Allan stayed at his residence after Alfredo was arrested, surrendered only in 2016 because a barangay kagawad told him to go to Kibungan, and denied owning the gardens. Allan’s sister Josephine testified that she saw spotlights coming from Alfredo’s house early that morning, saw Alfredo handcuffed, saw her three brothers leave with police around 7:00 a.m., and did not see any marijuana or wooden molder at Alfredo’s house. Allan’s brother Enero testified that police came at around 3:00 a.m., apprehended Allan and Alfredo, brought them to a garden around 7:00 a.m., and later took Alfredo away. Barangay Chairperson Pedanio Anatel testified that police directed him to Alfredo’s house, where he saw Alfredo handcuffed to a bed, saw Allan hiding at the back of the house leaning on the wall, and saw no media representative prior to his signing a document.

The trial court credited the prosecution’s evidence, found the elements of cultivation proved, and ruled that the integrity of the seized marijuana was preserved despite the arresting officers’ failure to strictly comply with the chain-of-custody rule. The Court of Appeals affirmed, finding that the prosecution established the elements, justified the deviations from the chain-of-custody rule, and proved that the integrity of the corpus delicti was preserved.

• Sufficiency of Evidence: Accused-appellant Allan argued that the prosecution failed to prove the elements of cultivation under Section 16 of Republic Act No. 9165.
• Chain of Custody: He pointed to numerous gaps and violations in the chain of custody that cast doubt regarding his guilt.
• Scope of Seizure and Inventory: He argued that the search and seizure in the second plantation and at Alfredo’s house could not be considered continuations of the first plantation search, and that separate inventories should have been prepared instead of a consolidated, confusing inventory.

• Justifiable Ground: The People, through the Office of the Solicitor General, argued that Team Omega’s noncompliance with Section 21 was justified by the remoteness of the area, the seven-hour hike from the drop-off point, and the distance between the plantation sites and the nearest police station.
• Substantial Compliance: The People maintained that the apprehending officers substantially complied with the law and that the procedural lapses did not affect the integrity of the confiscated drugs.

• Warrantless Arrest: Whether Allan’s warrantless arrest was valid as an in flagrante delicto arrest under Rule 113, Section 5(a).
• Chain of Custody: Whether the prosecution established the identity, integrity, and evidentiary value of the seized marijuana plants by proving an unbroken chain of custody and justifying the absence of the required insulating witnesses.
• Criminal Liability: Whether Allan is guilty beyond reasonable doubt of violating Section 16 of Republic Act No. 9165.

• Warrantless Arrest: Yes. Allan was caught in flagrante delicto tending to marijuana plants, an overt act committed within the view of the arresting officers, making his warrantless arrest valid.
• Chain of Custody: No. The first link was not established because no required insulating witnesses were present during the inventory and photographing of the seized plants, and the prosecution failed to justify the deviation or prove earnest efforts to secure their presence.
• Criminal Liability: No. Because the chain-of-custody violation created reasonable doubt as to the identity and integrity of the corpus delicti, Allan was entitled to acquittal despite the valid warrantless arrest.

• Warrantless Arrest: The Constitution generally requires a warrant, but permits reasonable warrantless arrests under Rule 113 of the Revised Rules of Criminal Procedure. Section 5(a) allows an arrest when the person has committed, is actually committing, or is attempting to commit an offense in the officer’s presence. The two required elements are: an overt act indicating the offense, and commission of that act within the presence or view of the arresting officer. Team Omega members saw Allan and Alfredo cleaning and weeding beds of marijuana seedlings from approximately ten meters away. That overt act corresponded to the crime of cultivation under Section 16, and therefore the warrantless arrest was lawful.

• Chain of Custody: In cultivation cases, the prosecution must prove to the point of moral certainty that the plants seized from the accused are the same ones examined by the laboratory and presented in court. The four links from People vs. Watamama require seizure and marking, turnover to the investigating officer, turnover to the forensic chemist, and submission to the court. The first link is governed by Section 21 of Republic Act No. 9165, and because the seizure occurred in 2011, three witnesses were required. IO1 Acosta’s testimony established that none of the required witnesses was present at the plantation inventories and photographing; only Team Omega and the two accused were present. The saving clause permits deviations only if the prosecution acknowledges lapses and proves justifiable grounds and preservation of integrity; People vs. Baluyot further requires earnest efforts to procure witnesses. Although the plantation was remote, the prosecution did not show that Team Omega took any step to secure witnesses despite the operation being planned. The unjustified deviation broke the first link.

• Criminal Liability: Noncompliance with the chain of custody prevents the prosecution from establishing the identity and integrity of the corpus delicti. The chain-of-custody violation was clear and unjustified. Thus, despite evidence that Allan was caught in flagrante delicto cultivating marijuana, the failure to prove the corpus delicti beyond reasonable doubt led to his acquittal.

• Chain of Custody Rule in Dangerous Drugs Cases — The prosecution must prove continuous custody from seizure to presentation in court through four links: seizure and marking by the apprehending officer; turnover to the investigating officer; turnover by the investigating officer to the forensic chemist; and turnover or submission from the forensic chemist to the court. The rule safeguards against doubts concerning the identity and evidentiary value of seized dangerous drugs or plant sources. In this case, the first link failed because no insulating witnesses attended the inventory and photographing at the plantations.

• Nisperos Guidelines for the First Link — Marking must be done immediately upon confiscation, at the place of confiscation, and in the presence of the offender unless the offender eluded arrest. Inventory and photographing must be done immediately after seizure and confiscation in the presence of the accused or representative and the insulating witnesses. For seizures during the original Section 21 regime from July 4, 2002 to August 6, 2014, three witnesses were mandatory: an elected public official, a Department of Justice representative, and a media representative.

• Saving Clause and Justifiable Grounds — Noncompliance with Section 21 does not automatically void the seizure if the prosecution acknowledges the lapses and proves two requisites: justifiable grounds for noncompliance, and preservation of the integrity and evidentiary value of the seized items. Justifiable grounds may include remoteness of the area, threats to safety, involvement of elected officials, futile efforts to secure witnesses, or time constraints. The prosecution must also prove that the arresting officers exerted earnest efforts to procure the required witnesses; mere unavailability is insufficient. The saving clause was not applied because no earnest effort was shown.

• Warrantless Arrest in Flagrante Delicto — Under Rule 113, Section 5(a) of the Revised Rules of Criminal Procedure, a warrantless arrest is lawful when the arrestee performs an overt act indicating that he or she has just committed, is actually committing, or is attempting to commit a crime, and that overt act is done in the presence or within the view of the arresting officer. Cleaning and weeding marijuana beds within the team’s view satisfied this doctrine.

• "In cases involving cultivation or culture of plants considered as dangerous drugs, the prosecution must prove to the point of moral certainty that the illegal flora which was planted, cultivated or cultured by the accused and seized by the apprehending officer/s are the very same flora which was examined by the laboratory and presented to court as evidence." — This states the controlling standard for proving the corpus delicti in cultivation cases and explains why a continuous chain of custody is essential.

• "Evidently, none of the required insulating witnesses were present when members of Team Omega inventoried and took photographs of the marijuana seedlings/plants that they supposedly seized from the plantations tended to by the accused-appellant, which is a clear violation of the first link in the chain of custody." — This is the majority’s fact-based conclusion identifying the specific first-link violation that defeated the prosecution’s evidence.

• "It is settled that the effect of noncompliance with the chain of custody is the failure on the part of the prosecution to establish the identity and integrity of the corpus delicti and such will lead to the acquittal of the accused for failure to prove their guilt beyond reasonable doubt." — This states the decisive legal consequence applied to the unjustified chain-of-custody violation.

• People vs. Watamama, 692 Phil. 102 (2012) — Followed; source of the four-link chain of custody test applied to the seized marijuana plants.
• Nisperos vs. People, 931 Phil. 945 (2022) — Followed; En Banc guidelines for marking, inventory, photographing, and the required insulating witnesses.
• People vs. Casa, 928 Phil. 356 (2022) — Followed; explained the Section 21 saving clause and its two requisites.
• People vs. Baluyot, 887 Phil. 173 (2020) — Followed; identified justifiable grounds and required proof of earnest efforts to secure the presence of witnesses.
• People vs. Bation, G.R. No. 237422, February 14, 2024 — Cited; applied the chain-of-custody requirement to prosecutions under Section 16 for cultivation of dangerous drugs.

• Article III, Section 2, 1987 Constitution — Guarantees the right against unreasonable searches and seizures and requires warrants based on probable cause. Applied to recognize that warrantless arrests are permissible when reasonable exceptions exist.
• Rule 113, Section 5, Revised Rules of Criminal Procedure — Governs warrantless arrests. Section 5(a) permits arrest when the offense is committed, attempted, or being committed in the officer’s presence. Applied to validate Allan’s in flagrante delicto arrest.
• Section 16, Republic Act No. 9165 — Defines and punishes cultivation or culture of dangerous drugs or their sources, including marijuana, regardless of quantity, without legal authority. Applied as the crime charged; although the elements were factually established, the conviction failed due to the chain of custody.
• Section 21, Republic Act No. 9165, as amended — Establishes the chain of custody requirement, immediate physical inventory and photographing of seized items, presence of the accused and insulating witnesses, and the saving clause. Applied to invalidate the evidentiary use of the seized marijuana plants because no required witnesses attended the plantation inventories and the saving clause was not satisfied.

Justices Gesmundo, C.J., Hernando, Inting, Zalameda, M. Lopez, Rosario, Dimaampao, Marquez, and Kho, Jr., concurred. Justice Caguioa filed a separate concurring opinion. He agreed with the acquittal but stressed that Section 21 must be strictly applied regardless of the quantity of dangerous drugs, citing People vs. Uy; he emphasized that the operation was planned and that a nearby “lupon” was not invited, negating any justifiable ground. Justice Singh was on leave.

• Senior Associate Justice Leonen — Argued that the Section 21 deviations were justified by the remoteness of the site and that the four chain links were established. He also reasoned that large quantities of non-fungible marijuana reduce the risks associated with noncompliance. He would have dismissed the appeal and affirmed the conviction. Justice Gaerlan joined this dissent.
• Justice Lazaro-Javier — Argued that the saving clause applied because the 5,000-square-meter marijuana plantation was a huge volume, the plants were not readily fungible or susceptible to planting or tampering, Team Omega took reasonable measures, and Allan’s escape and subsequent surrender indicated guilt. She would have affirmed the conviction.
