People of the Philippines vs. Maribel Lagman and Zeng Wa Shui

Possession of regulated drugs is malum prohibitum; criminal intent is not essential, but animus possidendi must be shown. Constructive possession exists when the drug is under the dominion and control of the accused or when the accused has the right to exercise dominion and control over the place where it is found, and such possession need not be exclusive. Furthermore, a search warrant need not identify the person against whom it is directed; only the place to be searched and the things to be seized must be described with particularity.

Acting on reports of clandestine shabu laboratories in Pampanga, the National Bureau of Investigation placed a piggery farm in Porac under surveillance in January 1996. The farm was reportedly a front, occupied by three Chinese nationals: Zeng Wa Shui, Li Wien Shien, and Jojo Gan. Maribel Lagman, the common-law wife of Jose “Bobby” Yu, regularly visited the farm and rented a house at 2609 San Francisco, Balibago, Angeles City, which she shared with Yu.

• The Surveillance and Raid: The NBI’s January 1996 surveillance of the Porac piggery established that Zeng Wa Shui, Li Wien Shien, and Jojo Gan occupied the property. Maribel Lagman frequented the farm and resided with her common-law husband Jose “Bobby” Yu at a rented house in Balibago, Angeles City. In the early morning of March 14, 1996, NBI agents armed with search warrants simultaneously raided both locations.

• Search of the Porac Farm: The search of the farm under Search Warrant No. 96-102 revealed no shabu laboratory, only pigs and two drums containing acetone and ethyl. The NBI team then conducted a stakeout. At 10:00 a.m., Li arrived in a blue Toyota Corolla; a search of his vehicle netted a digital weighing scale and approximately 317.60 grams of crystalline shabu. At noon, Zeng arrived driving an L-300 Mitsubishi van. In the open back of the van was a blue drum. The NBI chemist field-tested the drum’s liquid contents, which yielded a positive result for methamphetamine hydrochloride; the drum contained roughly 78 kilograms of liquid shabu.

• Search of the Balibago Residence: Under Search Warrant No. 96-101, the other NBI team proceeded to Lagman’s rented house. She was fetched from her place of business. The house contained two padlocked rooms; Lagman claimed she had no keys. Forcibly opened, the rooms contained 18 large plastic containers of liquid, 30 sacks of white powder, 10 plastic containers of white powder, plastic gallons, a refrigerator, a large blower, pails, plastic bags, a large glass flask, and a .25 caliber handgun. Field tests on six containers showed the liquid to be shabu (approximately 527 kilograms in total). The powder in the sacks was ephedrine hydrochloride (around 1,615 kilograms), and the liquid in 10 containers was sodium hydroxide — precursor chemicals in shabu production.

• Charges: Lagman was charged with (a) possession of 527 kg of shabu (Crim. Case No. 96-377) and (b) possession of 1,615 kg of ephedrine hydrochloride (Crim. Case No. 96-378). Li was charged with possession of 317.60 g of shabu (Crim. Case No. 96-379). Zeng was charged with possession of 78 kg of shabu (Crim. Case No. 96-380).

• The Accused’s Accounts: Lagman disclaimed knowledge of the drugs, asserting that Yu padlocked the rooms in November 1995 and January 1996, telling her the containers held fertilizers and restaurant items belonging to a friend who would collect them. She claimed she was rarely home as she tended a market stall and that she never checked the rooms. She also pointed to loan applications and a car sale as proof she lacked financial benefit from any drug syndicate. Li denied any role, stating he had only gone to the farm to buy piglets. Zeng denied knowing Lagman or Li, but admitted visiting the piggery four times after Gan offered him a manager position.

• Validity of Search Warrant (Lagman): Appellant Maribel Lagman argued that Search Warrant No. 96-101 was invalid because it did not specifically name her, rendering the seized items inadmissible against her.
• Constructive Possession (Lagman): She contended that the prosecution failed to prove her actual or constructive possession or intent to possess. She reiterated her lack of knowledge that the drugs were stored in the padlocked rooms, having relied on her common-law husband’s explanation that they were benign commercial goods.
• Documentary Evidence of Non-Involvement (Lagman): She faulted the appellate court for disregarding her loan applications and the Deed of Sale of her car, which she insisted demonstrated she did not profit from drug trafficking — otherwise, she would not have needed to borrow money or sell property.
• Illegal Seizure (Zeng): Appellant Zeng Wa Shui maintained that the 78 kilograms of liquid methamphetamine hydrochloride inside the blue drum was illegally seized because the drum was not covered by Search Warrant No. 96-102, was not formally offered in evidence, and therefore should have been excluded.
• Negative Averment — Lack of Authority (Zeng): He argued that the prosecution failed to prove a basic element of the crime — that he had no authority to possess the regulated substance.
• Purity of Substance (Zeng): He insisted that the finding that the liquid was methamphetamine hydrochloride was erroneous because no quantitative test on purity was conducted, in violation of Dangerous Drugs Board Resolution No. 3.

• Validity of Search Warrant: The Office of the Solicitor General (OSG) counter-argued that Search Warrant No. 96-101 sufficiently complied with Rule 126 of the Rules of Court because it described with particularity the place to be searched and the items to be seized; the Rules do not require that the accused be named.
• Constructive Possession: The OSG asserted that Lagman’s tenancy gave her dominion and control over the house, thus raising a presumption of knowledge and possession of the drugs found inside — a presumption she failed to rebut with any convincing evidence.
• Plain View Doctrine: The OSG maintained that the seizure of the blue drum was lawful because the NBI agents were legitimately present at the farm, and the drum lay in open view in the rear of the van, meeting all requisites of the plain view doctrine.
• Burden of Proof for Negative Averment: It was argued that the burden of proving lack of authority shifted to Zeng, as the existence of a license was a matter peculiarly within his knowledge; his failure to produce any document of authority warranted conviction.
• Immateriality of Purity Test: The OSG argued that the Dangerous Drugs Act penalizes unauthorized possession irrespective of purity; a qualitative identification was sufficient, and no quantitative examination was required either for conviction or for determining the imposable penalty.

• Validity of Search Warrant: Whether Search Warrant No. 96-101 was invalid for failing to identify Maribel Lagman with particularity.
• Constructive Possession: Whether the prosecution proved that Maribel Lagman had constructive possession and knowledge of the regulated drugs found in the padlocked rooms of her residence.
• Admissibility under Plain View Doctrine: Whether the methamphetamine hydrochloride seized from Zeng Wa Shui’s van was obtained through an unlawful warrantless search and should have been excluded.
• Proof of Lack of Authority: Whether the prosecution was required to adduce direct evidence that Zeng lacked a license or authority to possess methamphetamine hydrochloride.
• Requirement of Quantitative Examination: Whether a quantitative test to determine the purity of the seized substance was indispensable for conviction and imposition of the penalty.
• Propriety of Penalty: Whether the death penalty was correctly imposed, and whether its reduction was warranted under Republic Act No. 9346.

• Validity of Search Warrant: Search Warrant No. 96-101 was valid. Under Sections 3 and 4, Rule 126, a search warrant must particularly describe the place to be searched and the things to be seized; it need not identify the person against whom it is directed. The warrant described 2609 San Francisco Street, Angeles City, and listed the items to be seized with sufficient particularity. The phrase “and/or OCCUPANTS” satisfied the rule.
• Constructive Possession: Constructive possession was established against Lagman. Illicit drugs and paraphernalia discovered in a house occupied by a person raise a presumption of knowledge and possession sufficient to convict unless rebutted. Lagman, as the tenant, had full access to, control over, and dominion over the premises. Her inability to explain why she did not check the rooms or possess keys, combined with the unpersuasive nature of her documentary evidence — which was a non sequitur — meant she failed to overcome the presumption.
• Admissibility under Plain View Doctrine: The seizure from Zeng’s van fell within the plain view doctrine and was lawful. The NBI agents had a prior justification for intrusion because they were conducting a stakeout under a valid search warrant. The blue drum was in the open back of the van, plainly visible. The discovery was inadvertent, and the field test immediately revealed the liquid to be methamphetamine hydrochloride. All three requisites — lawful intrusion, inadvertent discovery, and immediately apparent incriminating nature — were satisfied.
• Proof of Lack of Authority: Direct proof of the negative averment was unnecessary. Where a criminal charge is predicated on a negative fact that does not readily admit of direct proof and is more immediately within the accused’s knowledge, the onus probandi shifts to the accused. Zeng could have easily disproved the allegation by presenting a license, permit, or other authority, but he failed to do so.
• Requirement of Quantitative Examination: A quantitative examination is not indispensable for conviction or for determining the penalty. The Dangerous Drugs Act penalizes unauthorized possession of the substance itself, regardless of purity. The NBI forensic chemist’s qualitative analysis confirmed the substance was methamphetamine hydrochloride, a finding presumed representative of the whole unless controverted. The penalty for possessing 200 grams or more is fixed by law based on weight, not purity.
• Propriety of Penalty: The trial court correctly imposed the death penalty given the quantities involved (more than 200 grams) and the absence of any modifying circumstances. However, with the enactment of Republic Act No. 9346, the death penalty was no longer available. The penalty was reduced to reclusion perpetua without eligibility for parole, and the fines were retained.

• Mala Prohibita Nature of Drug Possession — The crime of illegal possession of regulated drugs is malum prohibitum; criminal intent in its traditional sense is not an element. Nonetheless, the prosecution must still prove that the accused acted with animus possidendi (intent to possess).
• Constructive Possession — Under the Dangerous Drugs Act, possession embraces both actual and constructive possession. Constructive possession exists when the prohibited substance is under the dominion and control of the accused, or when the accused has the right to exercise dominion and control over the place where it is found. Exclusive control is not necessary; shared dominion with another does not exonerate the accused.
• Presumption from Presence of Drugs — The discovery of illicit drugs and paraphernalia inside a house or building owned or occupied by a particular person gives rise to a presumption of knowledge and possession on the part of that person, which standing alone can sustain a conviction. This presumption shifts the burden to the accused to offer a credible, rebutting explanation.
• Requisites for a Valid Search Warrant — A search warrant need not name the occupant or owner with particularity. The controlling requirements under Rule 126 of the Rules of Court are: probable cause determined personally by the judge after examining the applicant and witnesses; description of one specific offense; and particular description of the place to be searched and the things to be seized.
• Plain View Doctrine — Objects falling in plain view of a law enforcement officer who has a right to be in the position to have that view are subject to seizure without a warrant. The doctrine applies when: (a) the officer has a prior justification for the intrusion or is lawfully positioned to view the area; (b) the discovery of the evidence is inadvertent; and (c) it is immediately apparent that the item observed may be evidence of a crime, contraband, or otherwise subject to seizure.
• Burden of Proof on Negative Averments — When a charge rests on a negative allegation that does not permit direct proof, and the facts are more immediately within the knowledge and control of the accused, the onus probandi rests upon the accused. In illegal possession cases, the accused must show any license or authority to possess; otherwise, conviction follows.
• Irrelevance of Quantitative Purity Testing — The Dangerous Drugs Act penalizes the unauthorized possession of dangerous or regulated drugs irrespective of whether the substance is pure or unadulterated. Hence, a quantitative examination to determine purity is not an essential element of the crime, nor does it affect the penalty so long as the statutory weight threshold is met.

• “Possession, under the law, includes not only actual possession, but also constructive possession. Actual possession exists when the drug is in the immediate physical possession or control of the accused. On the other hand, constructive possession exists when the drug is under the dominion and control of the accused or when he has the right to exercise dominion and control over the place where it is found. Exclusive possession or control is not necessary. The accused cannot avoid conviction if his right to exercise control and dominion over the place where the contraband is located, is shared with another.” — The Court’s formulation of the two species of possession under the Dangerous Drugs Act.
• “The finding of illicit drugs and paraphernalia in a house or building owned or occupied by a particular person raises the presumption of knowledge and possession thereof which, standing alone, is sufficient to convict.” — The operative presumption applied to sustain Lagman’s conviction.
• “Objects falling in plain view of an officer who has a right to be in a position to have that view are subject to seizure even without a search warrant and may be introduced in evidence.” — The articulation of the plain view doctrine applied to the seizure from Zeng’s van.
• “Where the negative of an issue does not permit of direct proof, or where the facts are more immediately within the knowledge of the accused, the onus probandi rests upon him.” — The rule shifting the burden for negative averments such as lack of a license.
• “What the Dangerous Drugs Act punishes is the possession of the dangerous or regulated drugs or substances without authority. Whether the substance is pure or unadulterated is not material; hence, quantitative examination of the substance to determine its purity is not indispensable for conviction.” — The definitive rejection of the quantitative-test argument.

• People v. Tira, G.R. No. 139615, May 28, 2004, 430 SCRA 134 — Relied upon to enumerate the elements of illegal possession of regulated drugs and to define constructive possession.
• People v. Torres, G.R. No. 170837, September 12, 2006 — Followed for the principle that discovery of drugs in an occupied house raises a presumption of knowledge and possession sufficient for conviction.
• People v. Doria, G.R. No. 125299, January 22, 1999, 301 SCRA 668 — Applied for the three requisites of the plain view doctrine.
• People v. Manalo, G.R. No. 107623, February 23, 1994, 230 SCRA 309 — Invoked for the exception to the general rule on proving negative averments; where the matter is within the accused’s peculiar knowledge, the burden shifts.
• People v. Tang Wai Lan, G.R. Nos. 118736-37, July 23, 1997, 276 SCRA 24, and People v. Rasul, G.R. No. 146470, November 22, 2002, 392 SCRA 553 — Cited for the presumption that a chemist’s qualitative finding on a sample is representative of the entire bulk unless proven otherwise.

• Section 15, Article III, and Section 20, Article IV, Republic Act No. 6425, as amended by RA 7659 — Prescribe the penalty of reclusion perpetua to death and a fine of P500,000 to P10,000,000 for unauthorized possession of 200 grams or more of methamphetamine hydrochloride. The Court applied these to affirm the original death penalty and the fines, later reduced under RA 9346.
• Sections 3 and 4, Rule 126, Rules of Court — Govern the requisites for issuing a search warrant. The Court interpreted them as demanding particularity as to the place and things, not the person, thereby validating Search Warrant No. 96-101.
• Republic Act No. 9346, “An Act Prohibiting the Imposition of Death Penalty in the Philippines” — Enacted on June 24, 2006, it prohibited the imposition of the death penalty. The Court applied it to commute the death sentences of both appellants to reclusion perpetua without eligibility for parole.
