G.R. No. 233750 , June 10, 2019
PEOPLE OF THE PHILIPPINES, Plaintiff-Appellee, vs. ROMEL MARTIN y PEÑA, Accused-Appellant

FACTS

On August 3, 2011, the Tanauan City Police received an anonymous tip about rampant drug activity on Collantes Street. A team of ten officers, including PO2 Mafriel Magpantay and PO1 Harold Suriaga, conducted a roving operation. At around 4:30 p.m., they positioned themselves approximately nine meters away from an elevated nipa hut where they observed accused-appellant Romel Martin, Sheryl Pelago, and Bernardo Malocloc. The officers testified that they witnessed Martin hand a plastic sachet to Malocloc, who in turn gave money to Martin. Perceiving this as a drug transaction, the team moved in to arrest them. Malocloc was immediately apprehended, and one plastic sachet marked “HAS-1” was recovered from him. Martin and Pelago fled but were later caught after a pursuit. A body search on Martin allegedly yielded two more plastic sachets (marked “HAS-2” and “HAS-3”) and six 100-peso bills. An inventory of the seized items was conducted at the place of arrest in the presence of Barangay Captain Lourdes R. Ramirez. No representatives from the media or the Department of Justice (DOJ) were present. The items were forwarded to the crime laboratory, where they tested positive for methamphetamine hydrochloride.
Martin presented a starkly different version. He testified that he was at home sleeping when police officers arrived, arrested a neighbor, and then sought him out. He claimed he voluntarily opened his door, was frisked, and nothing illegal was found on him or in his house. He denied knowing Malocloc or participating in any drug transaction. He asserted that the arresting officers who testified were not the same ones who actually apprehended him.
The Regional Trial Court (RTC) found Martin guilty of illegal sale of dangerous drugs under Section 5 of Republic Act No. 9165 , sentencing him to life imprisonment and a fine. The Court of Appeals (CA) affirmed the RTC’s decision. Martin appealed to the Supreme Court.

ISSUE

Whether the Court of Appeals erred in affirming Martin’s conviction for violation of Section 5, Article II of R.A. No. 9165 , despite alleged breaches in the chain of custody of the seized drugs and the failure to comply with the witness requirements under Section 21 of the law.

RULING

The Supreme Court GRANTED the appeal, REVERSED the CA Decision, and ACQUITTED Romel Martin y Peña. The Court ordered his immediate release unless held for another lawful cause.
The acquittal was anchored on the prosecution’s failure to establish an unbroken chain of custody and to provide justifiable grounds for non-compliance with Section 21 of R.A. No. 9165 , which created reasonable doubt as to the identity and integrity of the corpus delicti.
Ratio Decidendi:
1. Primacy of the Chain of Custody in Drug Cases: In prosecutions for illegal sale of dangerous drugs, the identity of the prohibited drug must be established with moral certainty. The chain of custody rule ensures the integrity of the evidence from seizure to presentation in court. Any gap or unexplained deviation raises doubt about whether the item presented is the same one seized from the accused.
2. Fatal Non-Compliance with Section 21: The law mandates that immediately after seizure, the inventory and photography of the seized items must be conducted in the presence of the accused or his representative, a representative from the media, a representative from the DOJ, and an elected public official. In this case, only a Barangay Captain was present. The prosecution offered no explanation for the absence of the required media and DOJ representatives. The Court emphasized that while strict compliance may not always be possible, the prosecution must convincingly explain the deviation. Mere statements about earnest efforts or the unavailability of witnesses, without detailing what specific steps were taken, are insufficient.
3. Gaps in the Chain of Custody: The Court identified several critical lapses:
* First Link (Seizure and Marking): The prosecution failed to clearly establish who between PO2 Magpantay and PO1 Suriaga actually marked the items seized from Martin. Their testimonies were inconsistent on this crucial point. Marking upon immediate seizure is vital as it serves as the starting point of the custodial link.
* Second Link (Turnover to Investigating Officer): The records did not show how the items were transferred from the arresting officers to the investigating officer, PO3 Rowell Maala. There was no testimony or document detailing the transfer.
* Third Link (Turnover to Forensic Chemist): While PO2 Jaime was named as the evidence custodian, there was no testimony from her or any document showing how she received the items from the investigating officer and how she then delivered them to the crime laboratory.
4. Failure to Prove Justifiable Grounds: The prosecution did not acknowledge, much less justify, these lapses. The Court reiterated that the burden is on the prosecution to prove compliance with the chain of custody procedure or, in case of deviation, to provide a plausible explanation. Its failure to do so negated the presumption of regularity in the performance of official duties by the police officers.
5. Reasonable Doubt and Acquittal: Given the broken chain of custody and the unjustified non-compliance with Section 21, the integrity and evidentiary value of the seized drugs were compromised. Consequently, Martin’s guilt was not proven beyond reasonable doubt. The constitutional presumption of innocence prevails.

DOCTRINES

1. Chain of Custody Rule: In drug-related prosecutions, it is imperative that the identity of the dangerous drug be established with moral certainty. The prosecution must account for each link in the chain of custody: (a) seizure and marking; (b) turnover to the investigating officer; (c) turnover to the forensic laboratory for examination; and (d) turnover to the court. Unexplained gaps in this chain produce doubt as to the integrity of the corpus delicti and warrant acquittal.
2. Section 21, R.A. No. 9165 Compliance: The presence of the required witnesses (an elected public official, a representative from the DOJ, and a representative from the media) during the physical inventory and photographing of seized drugs is crucial to insulate the proceedings from any suspicion of switching, planting, or contamination. While non-compliance may be permitted under justifiable grounds, the prosecution bears the burden of proving such grounds. Mere allegation of earnest effort, without a detailed explanation of the steps taken, is insufficient.
3. Presumption of Regularity vs. Presumption of Innocence: The presumption that official duties have been regularly performed cannot prevail over the constitutional presumption of innocence accorded to the accused. The presumption of regularity is disputable and must yield when, as in this case, the prosecution has not convincingly established compliance with procedural safeguards designed to protect the rights of the accused.
4. Doubt in Favor of the Accused: Where the evidence for the prosecution fails to meet the test of moral certainty and leaves room for reasonable doubt as to the guilt of the accused, the Court is constitutionally bound to acquit. Any doubt is resolved in favor of the accused.
