Case Summary (G.R. No. 245972)
Factual Background: The Buy-Bust and Seizure
The prosecution described a pre-planned buy-bust operation based on a report concerning the drug activities of an alias “Jun” at Barangay East Rembo, Makati City. A briefing was allegedly held at around 9:00 p.m. on February 24, 2015, with PO2 Sherwin Limbauan designated as the poseur-buyer and PO1 Mario Pagulayan as back-up. The poseur-buyer was given a marked P1,000.00 peso bill. The team coordinated with the Philippine Drug Enforcement Agency by securing Coordination Form No. 0215-00272. When verification with the informant indicated that Jun was no longer in the area, the operation was suspended and the informant was instructed to call once Jun reappeared.
On February 25, 2015, the informant later called again to report Jun’s presence. The buy-bust team proceeded to 27th Avenue, Barangay East Rembo and then walked with the informant to the target area at 24th Avenue, while the rest of the team allegedly formed a perimeter around the area. Upon reaching the place, the informant and poseur-buyer allegedly observed two men standing together. The informant identified the taller man as Jun and introduced PO2 Limbauan as a friend looking to purchase shabu. The poseur-buyer offered P1,000.00 worth. Jun then instructed his companion, alias “Ato,” to receive the payment. PO2 Limbauan allegedly handed over the marked bill to Ato, while Jun supposedly handed one plastic sachet that appeared to contain shabu.
After PO2 Limbauan received the sachet, he allegedly pocketed it and executed a pre-arranged signal by scratching his ear. Thereafter, PO2 Limbauan allegedly arrested both Jun and Ato, introduced himself as a police officer, and frisked Jun. He recovered the marked bill and two additional sachets of suspected shabu from Jun. Nothing was allegedly recovered from Ato. The identities were later tied by the prosecution to the accused-appellants: Jun as Martin H. Asaytuno, Jr. and Ato as Renato H. Asaytuno.
According to the prosecution, after the arrest, an elected barangay official was called for the conduct of inventory, but none immediately arrived. As the crowd began to gather, the team decided to bring the accused and the seized evidence to the East Rembo Barangay Hall. There, an inventory was conducted in the presence of Kagawad Virgilio S. Awit. The sachet allegedly handed by Martin to PO2 Limbauan was marked “SCL.” The sachets recovered while frisking Martin were marked “SCL-1” and “SCL-2.” Photographs were taken, and the Inventory Receipt was received by PO3 Voltaire Esguerra, who then prepared letter requests for laboratory examination. The sachets were delivered to the Southern Police District for chemical analysis by PCI May Andrea Bonifacio, whose chemistry report indicated that all three sachets tested positive for shabu. The case thus rested critically on the prosecution’s ability to establish a reliable chain of custody over these very small quantities.
Defense Theory and Testimony
Both accused-appellants testified in their defense. Martin stated that between 12:00 a.m. and 12:30 a.m. on February 26, 2015, he was inside his room with his fifteen-year-old daughter folding clothes when several persons, later identified as police officers, entered their house, accompanied by an alias “Boteng.” He was allegedly grabbed, handcuffed, and frisked. His identification card and P20,000.00 were allegedly taken from his wallet. The police allegedly demanded that Martin produce shabu, but he denied having any. After shabu could not be found in his room, he was brought outside where he allegedly saw Renato also handcuffed. Martin’s account implied forcible entry, detention, and a lack of recovery of drugs from his supposed possession area.
Renato testified that he was suddenly woken up with a gun pointed to his face. He was allegedly handcuffed while someone searched his room. He later identified the police officers as members of the Station Anti-Illegal Drugs Special Operation Task Group of Makati City. He alleged that nothing illegal was found among his belongings, and that he was brought out and saw his brother. Both were allegedly transported to the station office and detained. The defense therefore denied guilt and raised substantial doubts about the seizure and handling of the alleged contraband.
RTC and Court of Appeals Rulings
After trial, the RTC, Branch 135, Makati City, convicted both accused. In Criminal Case No. 15-547, it found Martin and Renato guilty beyond reasonable doubt of violation of Section 5 of Republic Act No. 9165 for illegal sale of dangerous drugs. It sentenced them to life imprisonment and imposed a fine of P500,000 pesos. In Criminal Case No. 15-548, it found Martin guilty beyond reasonable doubt of illegal possession under Section 11, and sentenced him to an indeterminate term of twelve (12) years and one (1) day as minimum to fourteen (14) years as maximum, with a fine of PHP 300,000.00 pesos and costs. The RTC ordered turnover of 0.43 gram and 0.29 gram of methamphetamine hydrochloride for proper disposition by PDEA.
The Court of Appeals affirmed the RTC. It held that the elements of the offenses were established beyond reasonable doubt. It acknowledged that the chain of custody requirements were not strictly complied with but ruled that the deviations were justified. It further concluded that the seized items’ integrity was maintained.
Issues Raised on Appeal
The Supreme Court identified two main issues: first, whether Martin and Renato were guilty beyond reasonable doubt of illegal sale of dangerous drugs under Section 5; and second, whether Martin was guilty beyond reasonable doubt of illegal possession of dangerous drugs under Section 11.
Legal Framework: Elements and Corpus Delicti in Drug Offenses
The Court reiterated that conviction in criminal cases requires proof beyond reasonable doubt, consistent with the constitutional presumption of innocence. For illegal sale of dangerous drugs, the prosecution must prove, beyond reasonable doubt, the identity of buyer and seller, the identity of the object, the consideration, and in particular, the delivery of the thing sold and payment therefor. For illegal possession, the prosecution must prove the possession of a prohibited drug, lack of authorization by law, and the free and conscious possession of the drug by the accused.
In drug prosecutions, the Court emphasized that the corpus delicti is the seized drugs themselves. The Court relied on the doctrine that in illegal sale cases, the illegal drug constitutes the corpus delicti and its existence must be proved beyond reasonable doubt. The Court underscored that chain of custody rules perform a crucial evidentiary function: they ensure the removal of unnecessary doubt concerning the identity of evidence. Thus, the prosecution must establish that the drugs presented in court are the exact same drugs seized from the accused and examined by the crime laboratory. The Court treated this as substantive, not a procedural formality, rooted in the core of the offense.
The decision also highlighted the heightened vulnerability in handling narcotics. When the quantity is miniscule and the substances are fungible and not readily identifiable by appearance, the risks of tampering, loss, or substitution increase. Accordingly, the authentication standards must be stricter, requiring sequential and sufficiently complete custodial links to render exchange, contamination, or tampering improbable.
Chain of Custody Requirements Under Section 21 of Republic Act No. 9165
The Court anchored its analysis on Section 21 of Republic Act No. 9165, which outlines mandatory procedures for custody and disposition of seized dangerous drugs. It requires immediate physical inventory and photographing in the presence of the accused or persons from whom the items were confiscated and/or seized, an elected public official, and a representative of the National Prosecution Service or media, with compliance required for the inventory and photograph at the place where the search warrant was served or, for warrantless seizures such as buy-bust operations, at the nearest police station or office of the apprehending officer/team where practicable. Section 21 further requires submission within 24 hours to the PDEA forensic laboratory and laboratory certification under oath.
The Court further relied on the implementing chain of custody concept adopted in jurisprudence and connected it to the statutory requirement of strict compliance, or else a narrow allowance for justifiable noncompliance coupled with proof that integrity and evidentiary value were preserved.
Supreme Court’s Findings: Fatal Gaps in Marking, Transit, and Witness Requirements
The Court held that the prosecution’s account revealed multiple fatal violations that undermined the identity and integrity of the corpus delicti, warranting acquittal.
Marking not done immediately upon confiscation
The Court ruled that the prosecution’s own narration showed that after the alleged sale, PO2 Limbauan pocketed the sachet and that marking was done only after the team transferred to the barangay hall. The Court treated these circumstances as fatal. It cited People v. Sanchez, which distinguished marking from inventory and photographing and required that marking in warrantless seizures such as buy-busts be done immediately upon confiscation in the presence of the apprehended violator. Marking, as jurisprudence explains, involves the placement by the apprehending officer or poseur-buyer of initials and signature on the seized items, thereby separating the marked evidence from other similar substances from the moment of seizure.
In parallel, the Court invoked People v. Coreche, holding that failure to immediately mark after seizure causes an initial, fatal gap because later handlers rely on the markings as reference points to prevent switching, planting, contamination, or substitution. The Court rejected the prosecution’s claim that po

Case Syllabus (G.R. No. 245972)
- The case involved appeals by Martin H. Asaytuno, Jr. and Renato H. Asaytuno from a Court of Appeals decision affirming their conviction by the Regional Trial Court for illegal sale of dangerous drugs and, as to Martin, illegal possession of dangerous drugs.
- The Supreme Court resolved the appeal by examining whether the prosecution proved the corpus delicti beyond reasonable doubt through strict compliance with the chain of custody requirements under Republic Act No. 9165, as amended by Republic Act No. 10640.
- The Court held that law enforcers’ failure to strictly comply with Section 21 chain-of-custody requirements, coupled with the case’s miniscule drug quantity, prevented the prosecution from establishing the identity and integrity of the seized drugs.
- The Court therefore reversed the Court of Appeals decision and acquitted both accused for failure to prove guilt beyond reasonable doubt.
Parties and Procedural Posture
- People of the Philippines prosecuted Martin H. Asaytuno, Jr. and Renato H. Asaytuno for violations of Section 5 of Republic Act No. 9165 and, as to Martin, Section 11 of the same law.
- Upon arraignment, both accused pleaded “not guilty.”
- The Regional Trial Court convicted both accused for illegal sale of dangerous drugs and convicted Martin for illegal possession of dangerous drugs.
- The Court of Appeals affirmed the Regional Trial Court decision, holding that noncompliance with chain-of-custody requirements was justified and that the integrity of the evidence was maintained.
- The accused-appellants appealed to the Supreme Court, which framed the issues as whether guilt for illegal sale was proved beyond reasonable doubt and whether Martin was proved guilty beyond reasonable doubt of illegal possession.
Informations and Charged Offenses
- In Criminal Case No. 15-547, Martin and Renato were charged with illegal sale of dangerous drugs under Section 5 of Republic Act No. 9165.
- The Information alleged that on February 25, 2015 in Makati City, the accused willfully sold, delivered, and gave away Methamphetamine Hydrochloride (shabu) weighing zero point forty three (0.43) gram, in consideration of Php 1,000.
- In Criminal Case No. 15-548, Martin was charged with illegal possession of dangerous drugs under Section 11 of Republic Act No. 9165.
- The Information alleged that on February 25, 2015 in Makati City, Martin had in his possession zero point twenty nine (0.29) grams of Methamphetamine Hydrochloride, without lawful authorization.
Elements of the Offenses
- The Court reiterated that an accused enjoys the constitutional right to be presumed innocent and cannot be convicted without proof beyond reasonable doubt.
- For illegal sale of dangerous drugs, the Court required proof of: (one) the identity of the buyer and the seller, the identity of the object, and consideration of the sale; and (two) the delivery of the thing sold and the payment therefor.
- For illegal possession of dangerous drugs charged against Martin, the Court required proof of: (one) possession of an item identified as a prohibited drug; (two) lack of lawful authorization; and (three) free and conscious possession of the drug.
Corpus Delicti in Drug Cases
- The Court explained that in drug-related cases, the corpus delicti is the seized drugs themselves.
- The Court held that for illegal sale, the existence of the illegal drug as seized must be proved beyond reasonable doubt.
- The Court emphasized that the prosecution must show that the drugs presented in court are the exact same drugs seized from the accused and examined by the crime laboratory.
- The Court ruled that chain of custody performs a substantive evidentiary function by removing unnecessary doubts about the identity of the evidence.
- The Court applied doctrine that failure to establish the identity and integrity of the evidence naturally raises grave doubt and supports a finding that prohibited drugs may have been planted.
Peculiar Risks and Stringent Handling
- The Court discussed the heightened vulnerability of narcotics to tampering, loss, or substitution because they are small, fungible, and not readily identifiable by sight alone.
- The Court reasoned that when the Court cannot be assured that the items presented are the same as those seized and tested, it cannot be assured that the claimed transaction truly occurred.
- The Court stressed that standards for handling narcotics are stricter than for other materials because authentication requires a chain of custody with sufficient completeness.
Statutory and Regulatory Framework
- The Court quoted Section 21 of Republic Act No. 9165, which governs the custody and disposition of confiscated or seized dangerous drugs.
- The Court identified the statutory mechanism in Section 21(1) requiring physical inventory and photography in the presence of the accused or representative, with an elected public official and a representative of the National Prosecution Service or the media, who must sign the inventory and receive a copy.
- The Court noted the proviso that in warrantless seizures, the inventory and photograph may be conducted at the nearest police station or nearest office of the apprehending officer/team if not practicable at the place of seizure.
- The Court emphasized the final proviso of Section 21(1) that noncompliance may be excused only under justifiable grounds as long as integrity and evidentiary value are properly preserved.
- The Court also cited Dangerous Drugs Board Regulation No. 1, Series of 2002, defining chain of custody as duly recorded authorized movements and custody from seizure/confiscation to forensic laboratory receipt, safekeeping, presentation, and destruction.
Key Facts of the Buy-Bust
- The operation began after a report about the drug activities of an alias “Jun” at Barangay East Rembo, Makati City, and involved a pre-planned buy-bust.
- A briefing was held around 9:00 p.m. on February 24, 2015, with PO2 Sherwin Limbauan as poseur-buyer and PO1 Mario Pagulayan as back-up operative.
- The buy-bust team initially planned to proceed but learned that Jun was no longer in the area; the team suspended the operation and instructed the informant to contact them once Jun was spotted again.
- On February 25, 2015 at around 6:00 p.m., the informant called and reported that Jun was again seen at Barangay East Rembo.
- PO2 Limbauan and the informant walked to the target area while the rest of the team formed a perimeter.
- The informant identified the taller man as Jun, and Jun asked how much shabu PO2 Limbauan intended to buy, to which PO2 Limbauan responded P1,000.
- Jun instructed his companion, alias “Ato,” to receive payment, and PO2 Limbauan handed the marked P1,000 bill to Ato while Jun gave PO2 Limbauan one plastic sachet allegedly containing shabu.
- After receiving the sachet, PO2 Limbauan executed the pre-arranged signal and was followed by the apprehension of both Jun and Ato.
- The marked bill was recovered along with two other sachets of suspected shabu, while nothing was reportedly recovered from Ato.
- The persons were identified in court as Martin (Jun) and Renato (Ato).
- The team called for an elected barangay official for inventory, but none arrived immediately, so the operatives brought Martin and Renato and the seized evidence to the East Rembo Barangay Hall.
