Case Summary (G.R. No. 214472)

Procedural Posture and Relief Sought

Accused-appellant De Leon appealed to the Supreme Court from the Court of Appeals’ October 31, 2013 decision affirming the Regional Trial Court of Parañaque’s February 27, 2012 conviction for violation of Section 5, Article II of RA 9165. The Supreme Court reviewed whether the prosecution proved guilt beyond reasonable doubt and whether the procedures mandated by Section 21 were complied with or justifiably departed from.

Charged Offense and Elements

De Leon was charged with illegal sale of methamphetamine hydrochloride under Section 5, Article II of RA 9165. To sustain conviction the prosecution must prove beyond reasonable doubt: (1) the identity of buyer and seller, the object and the consideration; and (2) delivery of the thing sold and payment therefor. In drug cases the seized drug itself is the corpus delicti, and the identity and integrity of the seized substance must be established with moral certainty.

Pre-trial Admissions

The parties admitted: identity of the accused; jurisdiction of the trial court; that PI Abraham Tecson conducted the laboratory examination and reduced findings into Physical Science Report No. D-268-09S showing a positive test for methamphetamine hydrochloride; and that PI Tecson was not an eyewitness to the arrest circumstances.

Prosecution’s Case (Summary of Testimony and Evidence)

SPO1 Lumabao testified that an informant reported De Leon’s alleged peddling; the chief formed a buy-bust team and designated Lumabao as poseur buyer to purchase PHP 200.00 worth of shabu. Lumabao and the informant approached De Leon, Lumabao handed money and received a sachet, and he executed a pre-arranged signal (removing his cap). The team effected arrest; Lumabao marked the recovered sachet with his initials (“LL”) and prepared the inventory at the Barangay Hall in the presence of Barangay Tanod Melchor Alconaba. The specimen was brought to the PNP Crime Laboratory the same date and later tested positive. Exhibits identified included the sachet, request for examination, physical science report, joint affidavit, pre-operation forms, photographs, inventory, spot report, and booking sheet. SPO1 Macaraeg corroborated the sequence, testified he observed the pre-arranged signal and the arrest, and that he recovered the buy-bust money from De Leon.

Defense Case (Accused’s Testimony)

De Leon testified via her judicial affidavit that on June 2, 2009, men she had not seen before knocked, entered, and questioned her about a third person (Bolaret Mayuga). She was taken to the Drug Enforcement Unit, allegedly threatened to cooperate or remain detained, and told to produce money for her liberty; she denied involvement in drug activity and denied the sale. Cross-examination established that she had not met the arresting men previously and had no prior incident with them.

RTC’s Findings and Sentence

The Regional Trial Court (Branch 259, Parañaque City) convicted De Leon of illegal sale of dangerous drugs, imposing life imprisonment and a fine of PHP 500,000. The RTC credited the prosecution witnesses and found substantial compliance with Section 21 despite some procedural lapses, concluding the integrity of the seized drug was preserved. The RTC ordered transfer of the accused to the Women’s Correctional Facility and directed turnover of the specimen to PDEA for disposal.

Court of Appeals’ Ruling

The Court of Appeals affirmed the RTC, finding that the prosecution discharged its burden to prove illegal sale beyond reasonable doubt. The CA gave credence to police testimony (presuming regularity in duty), deemed there was valid justification for non-strict compliance with Section 21, and found an unbroken chain of custody from seizure to offering in court. The CA held that failure to inventory or photograph immediately did not render the evidence inadmissible in the circumstances.

Issue on Appeal to the Supreme Court

Whether the prosecution proved beyond reasonable doubt that De Leon committed illegal sale of dangerous drugs, taking into account compliance with Section 21’s requirements and the chain of custody for the seized sachet.

Supreme Court’s Holding (Disposition)

The Supreme Court granted the appeal, reversed and set aside the Court of Appeals decision, acquitted De Leon on the ground of reasonable doubt, and ordered her immediate release unless lawfully detained for another cause. The Court also ordered that an entry of final judgment be issued, the Correctional Institution for Women be notified for implementation, and directed the National Police Commission to investigate the police officers involved.

Basis for Acquittal — Failure to Comply with Section 21

The Supreme Court found the buy-bust team failed to comply with the mandatory procedural safeguards of Section 21 and the IRR. Key failures included: (1) lack of immediate marking of the seized sachet at the place of apprehension; (2) conducting marking, inventory and photographing at the Barangay Hall rather than at the place of seizure or nearest police station without adequate justification; and (3) absence of the mandatory three witnesses (accused or representative, an elected public official, a media representative, and a DOJ representative) at the time of inventory/photographing. The Court emphasized that Section 21’s “immediately after seizure and confiscation” requirement contemplates inventory and photographing at or near the site of apprehension, and the presence of the insulating witnesses at or near that time.

Chain of Custody, Marking, and Integrity of Corpus Delicti

The Court reiterated that the seized drug is the corpus delicti and its identity and integrity must be established with moral certainty. Immediate marking is the starting point of the custodial chain; delayed marking and absence of the required witnesses open the door to reasonable doubt by allowing the possibility of planting, switching, or contamination. The poseur buyer’s explanation that heavy rain prevented immediate marking and that no DOJ/media representatives were available due to weather was treated as uncorroborated and insufficient, especially in light of the short duration and planned nature of the operation.

Presumption of Regularity vs. Presumption of Innocence

The Supreme Court rejected the CA’s reliance on the presumption of regularity in official acts to cure procedural lapses. It held that the presumption of regularity cannot override the stronger constitutional presumption of innocence. Where affirmative indicia of irregularity exist, the presumption of regularity is unwarranted. The Court cited precedents warning against favoring police testimony with a presumption of regularity when procedural lapses are evident.

Police Operational Procedures and Additional Irregularities

The Court noted that internal police guidelines (1999 PNP Drug Enforcement Manual) required concrete operational steps in buy-busts—marking, photographing, inventorying, ensuring area security, and securing witnesses—and that these were not followed. Given that buy-bust operations are planned, the Court found it implausible that the team could not secure the required witnesses or perform immediat
