People vs. Leng Haiyun
Case
G.R. No. 242889
Decision Date
Mar 14, 2022
Foreign nationals fleeing after suspicious activity at a gas station were lawfully arrested, leading to the discovery of firearms and explosives in their vehicle, upheld by the Supreme Court.

Case Summary (G.R. No. 242889)

Issue

Whether the warrantless arrest, search, and seizure were lawful, and whether the convictions violate double jeopardy or lack proof of animus possidendi.

Ruling on Double Jeopardy and Animus Possidendi

The Court held that (1) there is no double jeopardy since the dismissed firearms possession case (Crim. Case No. 2132-19) involved a different offense from illegal possession of explosives (Crim. Case No. 2131-19) and the COMELEC gun-ban violation (Crim. Case No. 2133-19); and (2) animus possidendi is established by flight upon sighting police, the visibility of multiple weapons in the vehicle, and the implausibility of ignorance regarding their presence.

Warrantless Arrest under Section 5(b), Rule 113

The Court applied Section 5(b) (hot pursuit) rather than (a), finding that officers acted on personal knowledge of facts—Claveria’s report of bottle‐breaking (an alarm‐causing offense), immediate investigation, visual identification of the vehicle, the occupants’ flight, and interception at a checkpoint—all combining to create probable cause that an offense had just been committed.

Search and Seizure under Plain View Doctrine

Seizure in “plain view” was lawful where officers, already in a lawful position following a valid arrest, observed weapon parts under the second‐row seat upon opening the sliding door. The items were immediately recognizable as contraband without the need for a search warrant.

Search Incident to Lawful Arrest

As an incident to lawful arrest under Section 13, Rule 126, officers properly conducted a full inventory and search of the vehicle in the presence of senior police, barangay officials, media, and accused-appellants. The Toyota Previa was within the immediate control of the arrestees, and the search was contemporaneous with and justified by the valid warrantless arrest.
