Reasonable Doubt When Police Testimony Fails in Drug Cases

The Supreme Court has repeatedly emphasized that in drug cases, the prosecution must prove every element of the crime beyond reasonable doubt—including the legality of the arrest and the integrity of the seized evidence. When police officers fail to comply with constitutional requirements, even a seemingly straightforward drug possession case can collapse. In Reyes v. People (G.R. No. 229380, June 6, 2018), the Court acquitted a woman convicted of illegal drug possession after finding that the arresting officers acted on an unverified tip, conducted an invalid warrantless arrest, and failed to follow the chain of custody rule.

The Facts of the Case

On the evening of November 6, 2012, police officers in Cardona, Rizal were patrolling when two teenagers approached them with information that a woman with long hair and a dragon tattoo on her left arm had just bought shabu in a nearby barangay. Shortly after, the accused, Leniza Reyes, passed by the officers. She matched the description and smelled of liquor.

The officers asked if she bought shabu and ordered her to bring it out. According to the prosecution, Reyes turned her back, pulled a small plastic sachet from her breast area, and held it in her right hand. The police confiscated the sachet, which tested positive for 0.04 gram of methamphetamine hydrochloride. Reyes was charged with illegal possession of dangerous drugs under Section 11, Article II of Republic Act No. 9165.

Reyes denied the accusations. She claimed she was merely waiting for a jeepney when police officers blocked her ride, brought her to the station, and demanded P35,000.00 for her release.

The Issue Before the Court

The central question was whether Reyes's conviction for illegal possession of dangerous drugs should be upheld despite the circumstances of her arrest and the handling of the seized evidence.

The Ruling: No Valid Warrantless Arrest

The Court ruled in favor of Reyes, emphasizing that a warrantless arrest must comply with Section 5, Rule 113 of the Revised Rules of Criminal Procedure. Under this rule, a peace officer may arrest without a warrant when the person to be arrested has committed, is actually committing, or is attempting to commit an offense in the officer's presence, or when the officer has probable cause based on personal knowledge that the person committed an offense just committed.

The Court found that neither condition was met. PO1 Monteras admitted during cross-examination that Reyes passed by without acting suspiciously or doing anything wrong, except that she smelled of liquor. Walking while smelling of liquor is not a criminal act. The officers relied solely on an unverified tip from two teenagers—a hearsay tip that does not justify a warrantless arrest.

The "Overt Act" Test

For a valid in flagrante delicto arrest, the accused must exhibit an overt act within the view of the police officers suggesting possession of illegal drugs at the time of apprehension. In this case, no such overt act existed. The officers approached Reyes based purely on a description from strangers, not on any observed criminal behavior.

The Court also found the prosecution's version of events contrary to ordinary human experience. It is unlikely that a person would willfully exhibit incriminating evidence leading to her own conviction, absent any impelling circumstance. The prosecution's inconsistent claims—that Reyes was too intoxicated to know what she was doing, yet alert enough to remind officers they could not frisk a woman—further damaged the credibility of the police testimony.

Chain of Custody Violations

The Court also noted that the police officers committed unjustified deviations from the chain of custody rule under Section 21, Article II of RA 9165. Only the Barangay Captain was present during the marking and inventory of the seized items. The prosecution failed to show any effort to secure the presence of other required witnesses or provide justification for their absence.

Practical Takeaways

• Personal knowledge is essential. Police officers cannot rely solely on tips from informants to justify a warrantless arrest. They must have personal knowledge of facts indicating that a crime was committed.
• The overt act test matters. Mere presence in a location, matching a vague description, or smelling of liquor does not constitute an overt act suggesting criminal activity.
• Consensual searches require clear proof. For a search to be valid based on consent, the prosecution must show that the accused was expressly asked and clearly consented—established by clear and positive proof.
• Chain of custody is mandatory. The prosecution must prove compliance with Section 21, RA 9165, including the presence of required witnesses during inventory and photography, or provide justification for any deviation.
• Unreasonable searches produce inadmissible evidence. Evidence obtained from an invalid warrantless arrest is considered the "fruit of the poisonous tree" and cannot be used to convict.
