G.R. No. 74869 . July 6, 1988.
PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. IDEL AMINNUDIN y AHNI, defendant-appellant.

FACTS

Idel Aminnudin was arrested on June 25, 1984, upon disembarking from the M/V Wilcon 9 in Iloilo City. PC officers, acting on a tip from an informant that Aminnudin was transporting marijuana, were waiting for him. Without a warrant, they accosted him, inspected his bag, and found bundles later confirmed to be marijuana leaves. He was taken to headquarters, charged with violating the Dangerous Drugs Act, and subsequently convicted by the trial court and sentenced to life imprisonment. The trial court rejected Aminnudin’s defense that he was a watch seller arbitrarily arrested and manhandled, finding his story implausible.
Aminnudin appealed, contending his warrantless arrest and the search of his bag were illegal, rendering the seized marijuana inadmissible as evidence. The prosecution justified the arrest under Rule 113, Section 6(b) of the Rules of Court, pertaining to warrantless arrests when an offense has just been committed and the arresting officer has probable cause based on personal knowledge.

ISSUE

Was the warrantless arrest of Idel Aminnudin valid, thereby making the subsequent search incidental to a lawful arrest and the seized marijuana admissible as evidence?

RULING

No. The Supreme Court reversed the conviction and acquitted Aminnudin. The arrest was invalid as it did not fall under the recognized exceptions for warrantless arrests. The officers had no personal knowledge that an offense had just been committed or was being committed. The arrest was based solely on an informant’s tip received days prior. At the moment of arrest, Aminnudin was merely disembarking; no overt act indicated he was committing a crime in the officers’ presence. Consequently, the arrest being unlawful, the search incidental to it was likewise illegal. The marijuana seized was therefore the fruit of a poisonous tree and inadmissible as evidence against him.
The Court emphasized that while the campaign against illegal drugs is compelling, it cannot disregard constitutional rights. The Bill of Rights protects all individuals from high-handed enforcement. Without the illegally obtained evidence, the prosecution failed to prove Aminnudin’s guilt beyond reasonable doubt. The presumption of innocence prevails, necessitating his acquittal. The dissent argued the arrest was valid as he was caught in flagrante delicto, but the majority held that the tip alone, without contemporaneous confirmation of criminal activity, did not justify a warrantless arrest.
