Factual Background

Police received information about drug activities at Unit 4-B of HCL Building. From October 2–5, 1998, they conducted surveillance. On October 6, 1998, with a Chinese-speaking asset, they performed a test-buy of shabu valued at ₱2,000. No arrests were made pending a search warrant.

Pre-Warrant Operations: Surveillance and Test-Buy

• Witnesses SPO1 Anthony de Leon, PO2 Artemio Santillan, PO3 Albert Amurao testified to:
– Continuous monitoring of HCL Building.
– Controlled purchase confirming the substance as methamphetamine hydrochloride.

Issuance and Implementation of Search Warrant

• October 9, 1998: Judge Ramon Makasiar granted a warrant to search Unit 4-B, naming “Timothy Tiu.”
• October 12, 1998: Police, accompanied by building coordinator Noel Olarte and wife Joji, executed the warrant.
– Found in master’s bedroom:
• One black leather men’s handbag containing 234.5 g of shabu.
• One lady’s handbag containing 20.3673 g of shabu.
• An improvised tooter, weighing scale, burner, rolled tissue.
– Searched Honda Civic (no description in warrant) and seized 6.2243 g of shabu.

Defense’s Version

• Tiu Won denied being “Timothy Tiu” or residing in Unit 4-B; claimed marital residence elsewhere.
• Qui Yaling admitted occupancy of one room but denied ownership of the seized handbag.
• They asserted police misrepresentation, coerced entry by posing as electric collectors, and contested the search’s legality.
• Both denied knowledge or possession of shabu; claimed jewelry business dealings.

Trial Court Decision

• RTC Manila, Branch 27 (Aug 15, 2001) found respondents guilty beyond reasonable doubt of illegal possession of shabu.
• Sentenced both to reclusion perpetua and ₱500,000 fine.

Issues on Appeal

  1. Legality and sufficiency of the search warrant.
  2. Admissibility of seized evidence.
  3. Sufficiency of proof beyond reasonable doubt.
  4. Alleged violation of respondents’ constitutional rights.

Legality of the Search Warrant and Its Implementation

• Constitution requires warrants on probable cause personally determined by a judge, sworn examination of complainant and witnesses, and particular description of place and persons or things to be seized.
• Mistake in naming the person searched does not invalidate a warrant if:
– Place description is accurate.
– Officers had personal knowledge (surveillance, test-buy).
– “John Doe” warrants with sufficient descriptio personae are valid.
• The search of Unit 4-B complied with these requisites despite misnomer of “Timothy Tiu.”

Legality of the Vehicle Search

• Warrant did not authorize vehicle search.
• Warrantless search of the Honda Civic was invalid:
– Not incidental to lawful arrest (vehicle parked meters away).
– Exceeded scope of the warrant’s description.

Elements of Illegal Possession

To convict for lack of authorization under the Dangerous Drugs Act, prosecution must prove:

  1. Possession of a regulated drug (shabu).
  2. Lack of legal authority or prescription.
  3. Conscious and voluntary possession by the accused.
    • Good faith is immaterial; the offense is malum prohibitum.

Attribution of Possession to Each Accused

• No conspiracy alleged or proven; each accused’s possession must be individually established.
• Tiu Won admitted ownership of the men’s handbag containing 234.5 g of shabu.
• Qui Yaling’s in-court denial contradicted by admission that the ladies’ handbag was hers, containing 20.3673 g of shabu.
• Defense failure to present third-
