G.R. No. 262732 - People vs. Mongcao Basaula Sabino a.k.a. "Mongkao Basaola Sabino" a.k.a. "Salik" and Saima Diambangan Mipandong

Case Summary (G.R. No. 262732)

Factual Background

On March 30 and 31, 2018, a PDEA buy-bust team arranged a controlled purchase after a tip that an alias “Salik” had moved to Quezon City. The informant negotiated by phone for the sale of five hundred grams of shabu for PHP 1,250,000.00 to occur on March 31, 2018 at the parking lot of Robinsons Mall, Novaliches. PDEA agents marked ten pieces of PHP 100.00 bills and stacked them atop fake money to serve as buy-bust money. At about 9:20 a.m., a Toyota Revo with a man and woman later identified as Sabino and Mipandong pulled up next to the buy-bust vehicle. The informant invited them in, introduced Agent Anonas as the buyer, and Sabino handed a gray pouch which, when opened, contained four knot-tied plastic bags with white crystalline substance. The marked buy-bust money was handed to Mipandong. Other agents then announced themselves as PDEA agents and arrested both suspects. The agents seized the four plastic bags, the gray pouch, the marked buy-bust money, a mobile phone and identification from Sabino, and the Toyota Revo. The four plastic bags weighed respectively 147.3681, 133.2956, 125.2884, and 134.0457 grams, totaling 539.9978 grams. The seized items were marked at the place of arrest. The group proceeded to PDEA headquarters on NIA Road, Diliman, where an inventory was conducted in the presence of the accused and two insulating witnesses, Barangay Kagawad Marites Palma and radio reporter Jimmy Mendoza. Agent Anonas delivered the drugs to PDEA Laboratory Service at 3:15 p.m. the same day. Forensic chemist Anna Loe Montilla tested the four samples and reported they were positive for methamphetamine hydrochloride.

Trial Court Proceedings

Upon arraignment, both accused pleaded not guilty and underwent pre-trial and trial on the merits. The Regional Trial Court found the prosecution established the elements of illegal sale under Section 5 of Republic Act No. 9165, namely identity of buyer and seller, the object of the transaction, payment, and delivery. The RTC acknowledged that strict compliance with Section 21 had not been observed but held the corpus delicti was preserved from marking through turnover to the chemist. The RTC sentenced both accused to life imprisonment and a fine of Five hundred Thousand Pesos (P500,000.00).

Court of Appeals Decision and Appeal

The Court of Appeals affirmed the RTC decision. The CA invoked the exceptions discussed in People v. Sipin and applied the saving clause in Section 21, holding that deviations from the inventory procedure were justified in the circumstances and that the need for exacting compliance decreases when the seized quantity is not minuscule. The CA therefore denied the appellants’ appeal. The accused-appellants filed the present appeal to the Supreme Court.

Issue Presented

The sole issue before the Supreme Court was whether the prosecution proved beyond reasonable doubt the guilt of Mongcao Basaula Sabino and Saima Diambangan Mipandong for illegal sale of dangerous drugs under Section 5 of Republic Act No. 9165, in the context of arguments that PDEA agents did not strictly comply with the procedural safeguards of Section 21, as amended by Republic Act No. 10640.

Parties’ Contentions

The accused-appellants principally argued that PDEA agents failed to comply with the procedural requisites of Section 21, which require immediate inventory and photographing in the presence of the accused and insulating witnesses at the place of seizure, and that such noncompliance rendered the seizure invalid. The prosecution maintained that any deviation was justified, that the integrity and evidentiary value of the seized drugs were preserved, and that an unbroken chain of custody was established from seizure, marking, turnover, laboratory examination, and presentation in court.

Statutory Framework and Precedent

The Court examined Section 21, as amended by Republic Act No. 10640, including its saving clause that permits deviation for “justifiable grounds” provided the integrity and evidentiary value of the seized items remain preserved. The Court reiterated the two requisites established in People v. Taglucop for invocation of the saving clause: first, the existence of justifiable grounds for departure from strict compliance; and second, proof that the integrity and evidentiary value of the seized items were properly preserved. The Court also relied on the four-link chain-of-custody test articulated in People v. Adobar: seizure and marking; turnover to investigating officer; turnover to the forensic chemist; and submission of the marked sample to the court.

Court’s Findings on Section 21 Compliance and Chain of Custody

The Supreme Court found that the prosecution established justifiable grounds for conducting the inventory at PDEA headquarters rather than at the mall parking lot. The buy-bust occurred in an open-layout, high-traffic mall parking area near a tricycle terminal during a busy hour, making the scene volatile and posing safety risks and potential for commotion or interference. Agent Embang’s testimony supported that the agents sought to prevent commotion and risk to public safety. The Court further found that the integrity and evidentiary value of the seized items were preserved: the seized contraband was immediately marked and photographed; Agent Anonas had custody during transit; two insulating witnesses signed the inventory at PDEA headquarters; Agent Anonas turned the marked items over to Chemist Montilla who performed laboratory tests and identified the substance as methamphetamine hydrochloride; and the evidence was identified in open court by agents and the chemist. The Court concluded that the prosecution established an unbroken chain of custody and satisfied both requisites of Taglucop.

Credibility of Defense Alibi and Identity Issues

The Court assessed the accused-appellants’ alibi defenses and found them unworthy of belief. Each accused implicated several persons as corroborating sources—an aunt, a husband, a brother-in-law, and a friend—but none of those persons testified. The Court held that the absence of corroborating witnesses undermined the alibi claims and did not create reasonable doubt as to identity or the occurrence of the sale.

Ruling on Guilt and Sentence

The Supreme Court affirmed the convictions of Mongcao Basaula Sabino and Saima Diambangan Mipandong for violation of Section 5 of Republic Act No. 9165, finding guilt beyond reasonable doubt. The Court imposed life imprisonment and a fine of PHP 500,000.00 on each accused. The Court modified the sentence by deleting the phrase “without eligibility for parole” in accordance with A.M. No. 15-08-02-SC, clarifying the use of that phrase only in the context of
