Reasonable Doubt and Chain of Custody in Drug Cases: Lessons from People v. Quijano

In People v. Quijano (G.R. No. 247558, February 19, 2020), the Supreme Court affirmed the conviction of a detainee found possessing nearly 730 grams of shabu inside the Manila City Jail. The case illustrates how Philippine courts weigh animus possidendi (intent to possess) and the chain of custody rule in drug prosecutions under Republic Act No. 9165, as amended by RA 10640.

The Facts

On April 28, 2016, a jail officer at the Manila City Jail noticed a visitor receiving a light violet bag from someone inside the jail bakery. When summoned, the visitor handed the bag to Allan Quijano, a detainee. Quijano hesitated to approach the officer and tried to return the bag. Upon inspection, the bag contained a transparent plastic sachet of white crystalline substance later confirmed as 735.8 grams of methamphetamine hydrochloride, or shabu.

The seized items were marked, inventoried, and photographed in the presence of Quijano, the visitor, a prosecutor, a barangay official, and a police inspector. Quijano was charged with illegal possession of dangerous drugs under Section 11, Article II of RA 9165. The trial court convicted him, and the Court of Appeals affirmed. Quijano appealed to the Supreme Court.

The Issue

Quijano argued that he lacked animus possidendi because he merely held the bag for the visitor without knowing its contents. He also claimed the prosecution failed to establish an unbroken chain of custody, pointing to a discrepancy in the weight of the seized drugs.

The Ruling

The Supreme Court dismissed the appeal and affirmed the conviction. The Court held that all elements of illegal possession of dangerous drugs were present: Quijano possessed the prohibited drug, he had no legal authority to do so, and he freely and consciously possessed it.

On intent to possess. The Court explained that animus possidendi is a state of mind determined from the accused's prior and contemporaneous acts and surrounding circumstances. Mere denial of knowledge is insufficient. Possession of dangerous drugs constitutes prima facie evidence of knowledge, shifting the burden to the accused to explain its absence.

Quijano's own behavior negated his claim. He accepted the bag during a commotion, hesitated when summoned, and tried to return the bag when confronted. These acts, the Court said, were "unnatural and contrary to man's common experience" and indicated a guilty mind.

On chain of custody. The Court found the chain of custody unbroken. The marking, inventory, and photographing were done in the presence of required witnesses. The turnover to the forensic chemist was documented, and the Chemistry Report confirmed the drug's identity.

The Court also addressed the weight discrepancy. The Chemistry Report stated a net weight of 735.8 grams, but the gross weight during ocular inspection was 747.8 grams. The forensic chemist explained that the difference was due to the packaging material, the unstable weighing scale in court, and the different scale used in the laboratory. The Court found this explanation satisfactory, noting that the defense did not object when the prosecution manifested that the scale was unstable.

Practical Takeaways

• Intent to possess is inferred from conduct. Courts look at the accused's actions before and during the incident. Accepting a suspicious package during a commotion, hesitating to surrender it, and attempting to pass it to another person can establish animus possidendi.

• Mere denial is rarely enough. A bare claim of ignorance about the contents of a package will not overcome the prima facie presumption of knowledge arising from possession.

• Chain of custody requires each link accounted for. The prosecution must show the drug's movement from seizure to marking, turnover to the investigating officer, delivery to the forensic chemist, and presentation in court.

• Minor weight discrepancies may not be fatal. Courts accept reasonable explanations for variances, such as differences in weighing scales, packaging weight, or samples taken for testing—provided the drug's identity and integrity are preserved.

• Noncompliance with Section 21 is not automatic acquittal. Under RA 10640, noncompliance with inventory and photograph requirements does not render seizures void if justifiable grounds exist and the integrity of the seized items is preserved.
