G.R. No. 228519 - Xiuquin Shi vs. People

Case Summary (G.R. No. 228519)

Factual Background

On April 18, 2010, law enforcement conducted a buy‑bust operation at a 7‑Eleven convenience store along Dona Soledad Avenue, Better Living, Paranaque City, based on information concerning a target identified as Chua. The poseur‑buyer SPO3 Elmer Corbe and back‑up operatives met the target. After an introduction, the accused entered a vehicle. Corbe signaled completion of the transaction, at which point the team arrested the occupants. From the vehicle officers recovered one plastic bag involved in the sale and a black travelling bag containing fourteen sealed packages of white crystalline substance. The seized items were transported to Camp Bagong Diwa where they were inventoried, photographed, marked, and later submitted to the PDEA Crime Laboratory for examination.

Charges and Procedural History

By separate Informations dated April 20, 2010, the accused were charged in Criminal Case No. 10‑0400 with violation of Section 11 (possession) for the aggregate seizure of approximately 7,006.68 grams of methamphetamine hydrochloride and in Criminal Case No. 10‑0401 with violation of Section 5 (sale) for the alleged sale of 496.73 grams to the poseur‑buyer. All three accused pleaded not guilty at arraignment. The prosecution presented police operatives and stipulated chemists, while the defense presented the accused and disputed the integrity of the operation.

Evidence and Prosecution’s Case

The prosecution relied principally on the testimony of SPO3 Corbe, SPO2 Marcelo Alcancia, and SPO1 Randy Fuentes, documentary exhibits, photographic evidence, certificates of inventory, the request for laboratory examination, and Chemistry Report No. PDEA‑DD‑010‑146. Test results identified the seized specimens as methamphetamine hydrochloride. The prosecution established the sequence of arrest, marking, inventory, and transfer to the PDEA laboratory, and produced barangay officials who witnessed the inventory at Camp Bagong Diwa.

Defense Case

The defense denied guilt and alleged a frame‑up and extortion scheme by the arresting officers. Chua, Hong, and Sy testified that they were conducting legitimate business and that they were forced, restrained, and extorted for large sums of money. They asserted that the marking, inventory, and photographing were not conducted at the place of arrest and that the chain of custody was broken because of deviations from Section 21 of RA 9165, the absence of a DOJ representative and media witness, and the presence of a photographer who was not on the arrest team.

Trial Court Decision

The Regional Trial Court convicted Chua and Hong of illegal sale under Section 5 for the 496.73 grams sold to the poseur‑buyer and convicted all three accused of illegal possession under Section 11 for the approximately 7,006.68 grams recovered from the travelling bag. The court found the police witnesses credible, rejected the frame‑up allegations as unsubstantiated, and held that the police substantially complied with Section 21 of RA 9165 given the field conditions and the need to avoid compromising a follow‑up operation. The court sentenced those convicted to life imprisonment and imposed fines of P3,000,000 each.

Court of Appeals Decision

On appeal, the Court of Appeals affirmed the trial court’s findings and convictions in a decision dated June 6, 2016. The appellate court weighed the positive identification by the poseur‑buyer, the circumstances supporting constructive possession by the passengers, and the preservation of the evidentiary integrity of the seized items. It held that deviations from the chain of custody procedures were justified by the circumstances and that the prosecution established the identity and continuity of the seized items.

Issues on Possession and Chain of Custody

The principal contested issues concerned whether petitioner Sy had the requisite animus possidendi to sustain a conviction for possession and whether the prosecution maintained an unbroken and legally sufficient chain of custody for the seized drugs despite deviations from Section 21 of RA 9165 in marking, inventory, witnessing, and photographing.

Supreme Court’s Analysis and Ruling

The Supreme Court held that the prosecution proved beyond reasonable doubt the elements of illegal sale by Chua and Hong and illegal possession by Chua, Hong, and Sy. The Court treated the law in force at the time — RA 9165 prior to amendment by RA 10640 — as governing. It found SPO3 Corbe’s positive identification of the sellers credible and found that the fourteen packages discovered in the travelling bag on Hong’s lap were in the constructive possession of all occupants, including Sy.

Legal Reasoning on Constructive Possession and Chain of Custody

On constructive possession, the Court reiterated that possession includes actual and constructive possession, and that the presence of prohibited drugs in a place under the dominion and control of a person raises a presumption of knowledge or animus possidendi which the accused must satisfactorily rebut. The Court found that Sy failed to rebut that presumption because the vehicle was jointly used by her and her husband, she witnessed the transaction and exchange of large cash for the package, she remained silent during the suspicious events, and she attempted to make a phone call upon announcement of the arrest, all of which the Court regarded as indicia of guilty knowledge or acquiescence. On the chain of custody, the Court applied the four‑link framework and concluded that the prosecution substantially complied. The Court accepted justifiable grounds for deviation from the literal requirements of Section 21 where immediate inventory at the arrest scene would have jeopardized officer safety and a possible follow‑up operation, given the large volume of seized items and the short distance to Camp Bagong Diwa.
