G.R. No. 168695 - People vs. Lagman

Case Summary (G.R. No. 168695)

Factual Background

NBI agents, after receiving reports of clandestine shabu laboratories, conducted surveillance in January 1996 of a piggery farm in Porac and of a house at 2609 San Francisco, Balibago, Angeles City, rented by Maribel and shared with her Chinese common-law husband, Jose "Bobby" Yu. On March 14, 1996 two NBI teams executed simultaneous raids pursuant to search warrants. The raid of the Porac farm (Search Warrant No. 96-102) initially yielded only pigs and two drums whose field-tests showed acetone and ethyl. During the stakeout, Li Wien Shien arrived in a blue Toyota Corolla; a search of his vehicle produced a digital scale and a packet of crystalline substance weighing approximately 317.60 grams which field-tested positive for shabu. Later the same day Zeng arrived in an L-300 Mitsubishi van which contained a blue drum of liquid that field-tested positive for shabu. The Balibago residence (Search Warrant No. 96-101) yielded two padlocked rooms forcibly opened by NBI agents, revealing eighteen large plastic containers with liquid, sacks and plastic containers with white powdery substances, laboratory paraphernalia, and a .25 caliber handgun; field-tests showed shabu in some containers, ephedrine hydrochloride in the sacks, and sodium hydroxide in other containers.

Indictments and Charges

The prosecution filed separate informations. Maribel faced Criminal Case No. 96-377 for possession of approximately 527 kilograms of methamphetamine hydrochloride in liquid form and Criminal Case No. 96-378 for possession of approximately 1,615 kilograms of ephedrine hydrochloride. Li was indicted in Criminal Case No. 96-379 for possession of approximately 317.60 grams of methamphetamine hydrochloride. Zeng was indicted in Criminal Case No. 96-380 for possession of approximately 78 kilograms of methamphetamine hydrochloride. The cases were consolidated for trial in Branch 59, RTC Angeles City.

Defenses and Contentions at Trial

Maribel disclaimed knowledge of the contraband in the padlocked rooms, asserting that Yu had placed and padlocked the containers and sacks, had borne the rent and household expenses, and had been away much of the time. She admitted that Zeng had visited her house and that Yu had twice brought her to the Porac piggery, but denied knowledge of any drug operation. Li denied knowing or participating in any laboratory operation and claimed he had merely gone to buy piglets. Zeng denied knowledge of Maribel and Li, admitted knowing Gan, and stated he had visited the piggery at Gan's request to consider employment as manager.

Trial Court Proceedings and Disposition

The trial court, after trial, acquitted Li but convicted Maribel and Zeng. By Decision dated July 20, 1988, the trial court imposed the death penalty on both Maribel and Zeng and assessed fines of P2,000,000 against Maribel and P1,000,000 against Zeng. The trial court’s findings included acceptance of NBI testimony regarding the discovery and field-testing of seized substances and a conclusion that Maribel had constructive possession of the contraband found in the rented house.

Court of Appeals Proceedings

The Court of Appeals affirmed the convictions by Decision dated June 6, 2005. Maribel challenged the validity of Search Warrant No. 96-101 as failing to identify her with particularity and contested the finding of constructive possession. Zeng contested admissibility of the blue drum content recovered from his van and argued the prosecution failed to prove lack of authority to possess the substance and failed to establish purity through quantitative testing. The Court of Appeals rejected these contentions and affirmed the RTC.

Issues Presented on Appeal to the Supreme Court

The appellants raised primarily: (1) the validity and sufficiency of Search Warrant No. 96-101 and the admissibility of evidence seized thereunder; (2) whether Maribel had constructive possession and knowledge of the regulated substances found in her rented house; (3) whether the blue drum in Zeng’s van was lawfully seized and admissible; (4) whether the prosecution proved the negative element that the accused lacked lawful authority to possess the regulated drugs; and (5) whether quantitative testing to determine purity was required to convict or to fix penalty.

Supreme Court Ruling and Disposition

The Supreme Court affirmed the Court of Appeals’ decision with modification. It sustained the convictions of Maribel Lagman and Zeng Wa Shui for violation of the Dangerous Drugs Act as charged. Because of the subsequent enactment of R.A. No. 9346, abolishing the death penalty, the Court modified the sentence to reclusion perpetua without eligibility for parole and ordered Maribel to pay a fine of Two Million (P2,000,000.00) Pesos and Zeng to pay a fine of One Million (P1,000,000.00) Pesos.

Legal Basis and Reasoning on Possession and Knowledge

The Court reiterated the essential elements of illegal possession of regulated drugs: (1) actual possession of an item identified as a prohibited drug; (2) possession without lawful authority; and (3) the accused freely or consciously possessed the drug. The Court noted that illegal possession is a mala prohibita offense and that although criminal intent is not an essential element, the prosecution must prove the accused’s intent to possess (animus possidendi). The Court explained constructive possession as dominion and control, or the right to exercise such dominion and control, over the place where contraband is found, and observed that exclusive possession is not necessary; shared control suffices to sustain constructive possession.

Validity of Search Warrant No. 96-101

Addressing Maribel’s contention that Search Warrant No. 96-101 was invalid for lack of particular identification of the person against whom it ran, the Court applied Sec. 3 and Sec. 4, Rule 126, Rules of Court, and held that the requisites for a valid warrant are probable cause and particular description of the place to be searched and things to be seized. The Court found that the warrant sufficiently described the place and the items to be seized and that Rule 126 does not require that the warrant identify the person with particularity.

Plain View Seizure and the Drum in Zeng’s Van

Concerning the seizure from Zeng’s van, the Court found the plain view doctrine applicable. It recited the doctrine’s requisites: lawful intrusion or position to view the area, inadvertent discovery, and immediate apparent character of the item as evidence or contraband. The Court observed that Zeng was named in Search Warrant No. 96-102, that he entered the area under surveillance, and that the blue drum was in the open back of his van and thus visible to NBI agents. The Court therefore deemed the seizure lawful even though the drum was not explicitly recited in Search Warrant No. 96-102.

Key Factual Allegations

The National Bureau of Investigation conducted surveillance of a piggery farm in Porac and of a rented house at 2609 San Francisco, Balibago, Angeles City, both suspected as fronts for a shabu laboratory.
The Porac farm search under Search Warrant No. 96-102 initially yielded only pigs and two drums containing acetone and ethyl as determined by an NBI field test.
During an NBI stakeout at the farm, a blue Toyota Corolla driven by Li was searched and yielded a digital scale and a packet of crystalline substance weighing approximately 317.60 grams that field-tested positive for shabu.
Later that day an L-300 Mitsubishi van driven by Zeng arrived at the farm and its open back contained a blue drum with liquid that field-tested positive for methamphetamine hydrochloride.
The Balibago residence search under Search Warrant No. 96-101 produced two padlocked rooms that, when forcibly opened, yielded eighteen large plastic containers of liquid, thirty sacks of white powder, ten plastic containers of a white powder, assorted laboratory paraphernalia, and a .25 caliber handgun.
