Facts Found at Trial
NBI surveillance identified three Chinese nationals frequenting a Porac piggery and connections to Maribel’s Balibago residence. Two NBI teams executed simultaneous searches under Search Warrants Nos. 96-102 (Porac farm) and 96-101 (Balibago residence). At the piggery: field tests identified acetone and ethyl in drums; a search of Li’s vehicle produced a digital scale and a 317.60-gram crystalline packet testing positive for shabu; Zeng arrived later in an L-300 van with a blue drum whose liquid tested positive for methamphetamine hydrochloride. At the Balibago residence: two padlocked rooms forcibly opened by the raiding team yielded 18 large plastic containers with liquid (six tested positive for shabu), 30 sacks of white powder (ephedrine hydrochloride), and other chemicals and paraphernalia used in shabu manufacture, plus a .25-caliber handgun.
Criminal Charges
- Maribel: Two informations — possession of approximately 527 kg of shabu (Crim. Case No. 96-377) and possession of approximately 1,615 kg of ephedrine hydrochloride (Crim. Case No. 96-378).
- Li: Possession of approximately 317.60 grams of methamphetamine hydrochloride (Crim. Case No. 96-379).
- Zeng: Possession of approximately 78 kilograms of methamphetamine hydrochloride found in his van (Crim. Case No. 96-380). Cases consolidated in RTC Branch 59, Angeles City.
Trial Court and Appellate Outcomes
- Trial court acquitted Li but convicted Maribel and Zeng, imposing the death penalty and fines (P2,000,000 on Maribel; P1,000,000 on Zeng).
- Court of Appeals affirmed convictions.
- On appeal to the Supreme Court, the convictions were affirmed but the death penalty was converted to reclusion perpetua without eligibility for parole pursuant to RA 9346 (abolition of death penalty); fines were imposed as affirmed (P2,000,000 for Maribel; P1,000,000 for Zeng).
Legal Elements of the Offense and Burden of Proof
- The court reiterated the essential elements of illegal possession of regulated drugs: (1) possession of an identified prohibited drug, (2) possession not authorized by law, and (3) the accused freely or consciously possessed the drug (animus possidendi). Although illegal possession under the Dangerous Drugs Act is mala prohibita (criminal intent not an essential element), the prosecution must still prove intent to possess; possession may be actual or constructive. Constructive possession exists where the drug is under the dominion and control of the accused or where the accused has the right to exercise dominion and control over the place where the drug is found. Exclusive possession is not required; shared dominion suffices to sustain constructive possession.
Presumption from Discovery in Occupied Premises
- The court applied the presumption that discovery of illicit drugs and paraphernalia in a house or building owned or occupied by a person raises an inference of knowledge and possession sufficient for conviction, absent adequate rebuttal. Maribel, as tenant, had access, control, and dominion over the rooms where contraband was stored. The Court found her explanations inadequate: she offered no satisfactory reason why she did not inspect the padlocked rooms (allegedly locked by Yu) or why she lacked keys, and documentary evidence of financial distress (loan applications, deed of sale of car) did not rebut the constructive possession presumption. The court treated her claimed ignorance as unconvincing.
Validity of Search Warrant No. 96-101 and Particularity Requirement
- Maribel argued the warrant was invalid for not identifying her by name. The court analyzed Rule 126, Sections 3 and 4, and concluded that the Rules require particular description of the place to be searched and the things to be seized, not identification by name of the person against whom the warrant is directed. The wording of Search Warrant No. 96-101 specifically described the address (2609 San Francisco Street) and enumerated the controlled substances and paraphernalia to be seized, satisfying the Rule’s requisites for specificity and probable cause. Therefore, the search warrant was valid and evidence seized pursuant thereto was admissible.
Plain View Doctrine and Seizure from Zeng’s Van
- Zeng contended the blue drum in his van was not covered by Search Warrant No. 96-102 and thus the evidence was illegally obtained. The court applied the plain view doctrine, noting the constitutional protection against unreasonable searches and seizures is not absolute and recognizes exceptions. The plain view doctrine requires: (a) a lawful justification for the officer’s presence in a position to view the object; (b) inadvertent discovery; and (c) immediately apparent incriminating character of the object. Zeng arrived within the area covered by the approved stakeout and the warrant named him as a subject; the blue drum containing liquid was in the open back of the van, visible and accessible to NBI agents. The court found the seizure lawful under plain view, and the field tests by NBI chemist Bautista that identified the liquid as methamphetamine hydrochloride were credited.
Burden Regarding Negative Averment of Authority to Possess
- Zeng asserted the prosecution failed to prove the negative averment that he lacked lawful authority to possess methamphetamine hydrochloride. The court explained the general rule that the prosecution must prove negative allegations, with an exception where the negative averment is

Factual Background — Investigative Surveillance and Raids
- In January 1996, following reports of clandestine shabu laboratories in Pampanga, the National Bureau of Investigation (NBI) conducted surveillance of a piggery farm in Porac allegedly used as a front.
- Surveillance determined that three Chinese nationals — Zeng Wa Shui, Li Wien Shien, and Jojo Gan — occupied the farm; Maribel frequented the piggery and Zeng and Li would visit Maribel’s rented house at 2609 San Francisco, Balibago, Angeles City, which she shared with her Chinese common-law husband Jose "Bobby" Yu.
- On the early morning of March 14, 1996, two NBI teams simultaneously executed search warrants: Search Warrant No. 96-102 for the Porac farm and Search Warrant No. 96-101 for the Balibago residence.
- The raiding team at the farm initially found no persons and located only pigs and two containers/drums later field-tested positive for acetone and ethyl (NBI chemist Januario Bautista).
- Raiding team closed the farm gates and awaited arrivals; around 10:00 a.m., Li arrived in a blue Toyota Corolla; search of Li’s vehicle yielded a digital weighing scale and a packet with crystalline substance weighing approximately 317.60 grams, field-tested positive for shabu.
- Around 12:00 noon, Zeng arrived in an L-300 Mitsubishi van bearing a blue drum containing liquid; the drum’s liquid, when field-tested on the spot by NBI chemist Bautista, was found positive for shabu.
- The team that executed Search Warrant No. 96-101 at the Balibago residence found two padlocked rooms; Maribel was fetched from her place of business; the team forcibly opened the padlocked rooms upon Maribel’s claim of lacking keys.
- Seized at Balibago: 18 large plastic containers containing liquid; 30 sacks with white powdery substance; 10 plastic containers with white powdery substance; plastic gallons; a refrigerator; a big blower; pails; plastic bags; a large glass flask; and a .25 caliber handgun.
- Field tests: liquid in 6 of the 18 containers tested positive for shabu; drums’ liquids were alcohol solvents; powder in sacks determined to be ephedrine hydrochloride; liquid in 10 plastic containers determined to be sodium hydroxide — chemicals identified as used in manufacture of shabu.
Specific Quantities and Items Seized
- From Balibago residence (attributable to Maribel’s possession counts): approximately 527 kilograms of shabu in liquid form (Crim. Case No. 96-377) and approximately 1,615.0 kilograms of ephedrine hydrochloride (Crim. Case No. 96-378).
- From Li’s vehicle: approximately 317.60 grams of methamphetamine hydrochloride (Crim. Case No. 96-379).

Defenses Offered by Appellants
- Maribel’s defenses:
- Disclaimed knowledge of regulated substances and paraphernalia kept in the padlocked rooms of the house she had shared with Jose "Bobby" Yu since 1994; alleged Yu placed and padlocked the containers and sacks in November 1995 and January 1996 and told her they were fertilizers and restaurant items belonging to a friend.
- Claimed Yu shouldered rent and household expenses and was away most of the time; she tended a store in the public market and was not home frequently.
- Asserted lack of keys to the padlocked rooms and no knowledge of the contents; contested the admissibility of evidence seized by Search Warrant No. 96-101 on the ground that the warrant did not specifically state her name.
- Submitted documentary evidence (loan applications, deed of sale of her car) intended to show she had no involvement in drug operations — argued these documents indicated no need to borrow money or sell car if involved in drug syndicate.
- Zeng’s defenses:
- Argued the blue plastic container (drum) containing methamphetamine was illegally obtained and inadmissible, and that the drum was not included in Search Warrant No. 96-102.
- Claimed prosecution failed to prove he lacked authority or license to possess the substance.
