People vs. Mariacos

A warrantless search of a bag or container aboard a moving vehicle is valid as a search of a moving vehicle when supported by probable cause and the exigency of the vehicle’s mobility; the subsequent warrantless arrest of a person caught transporting the contraband is lawful as an arrest in flagrante delicto; and non‑compliance with the inventory and photograph requirements of Section 21 of Republic Act No. 9165 does not render the seized drugs inadmissible provided the integrity and evidentiary value of the items are preserved.

On October 26, 2005, the San Gabriel Police Station in La Union received information that marijuana would be transported from Barangay Balbalayang. A checkpoint near the station yielded no suspects. The following dawn, a police officer met an agent of the Barangay Intelligence Network who reported that baggage containing marijuana had been loaded onto a passenger jeepney about to leave for the poblacion. The officer boarded the jeepney, found a black backpack with an “O.K.” marking, and inspected its contents without a search warrant, discovering bricks of marijuana. When the jeepney reached the poblacion, the officer saw two women carrying the bags away; he arrested one of them — Belen Mariacos — while the other fled. The bags were opened at the police station, and the seized marijuana, weighing 7,030.3 grams, tested positive for the drug. Mariacos was charged under Section 5, Article II of Republic Act No. 9165 with transportation of dangerous drugs.

• The Tip and Surveillance: On the evening of October 26, 2005, the San Gabriel Police Station in La Union set up a checkpoint near the station to intercept a suspected transport of marijuana from Barangay Balbalayang. No suspect or marijuana was found. The Chief of Police then directed PO2 Lunes B. Pallayoc to proceed to Barangay Balbalayang to conduct surveillance. At dawn on October 27, 2005, PO2 Pallayoc met a secret agent of the Barangay Intelligence Network in the barangay, who informed him that a baggage of marijuana had been loaded onto a passenger jeepney about to leave for the poblacion. The agent described three bags and one blue plastic bag, and specifically mentioned a backpack with an “O.K.” marking.

• The Search Aboard the Jeepney: PO2 Pallayoc boarded the same jeepney and positioned himself on top. While the vehicle was in motion, he found a black backpack bearing the “O.K.” marking. He peeked inside the bag and saw bricks of marijuana wrapped in newspapers. He asked the other passengers on top about the bag’s owner, but no one claimed it.

• Arrest and Seizure: When the jeepney reached the poblacion, PO2 Pallayoc alighted along with other passengers. He did not immediately see who took the black backpack, but moments later he noticed the black bag and three other bags, including a blue plastic bag, being carried away by two women. He caught up with them, introduced himself as a police officer, and told them they were under arrest. One woman escaped; the other, later identified as Belen Mariacos, was secured and brought to the police station together with the bags.

• Custody and Examination: At the police station, the investigators asked the Mayor of San Gabriel to witness the opening of the bags. The Mayor arrived about 15 minutes later. The bags were opened in Mariacos’s presence, revealing three bricks of marijuana wrapped in newspaper, two round bundles of marijuana, and two bricks of marijuana fruiting tops, all wrapped in newspaper. PO2 Pallayoc and PO3 Stanley Campit marked the items and forwarded them to the PNP Crime Laboratory. The laboratory examination confirmed the substance was marijuana, a dangerous drug, with a total weight of 7,030.3 grams. No photographs were taken during the inventory, and no representative from the media or the Department of Justice (DOJ), and no counsel for Mariacos, were present.

• The Defense Version: Mariacos testified that she and a companion, Lani Herbacio, were inside the jeepney bound for the poblacion at around 7:00 a.m. on October 27, 2005. While waiting at the terminal, a neighbor, Bennie Lao‑ang, asked her to carry some bags that had been loaded on top of the jeepney. She initially refused but was persuaded when told she would only be carrying them. When they alighted at the poblacion, Lao‑ang handed the bags to her and Herbacio and then suddenly ran away. Moments later, PO2 Pallayoc approached and arrested them without explanation. At the police station, Herbacio disappeared. Mariacos maintained she was not the owner of the bags and did not know their contents until they were opened at the station. She executed a counter‑affidavit.

• Warrantless Search and Seizure: Mariacos argued that her right against unreasonable searches was violated when PO2 Pallayoc searched the backpack without a search warrant and without her permission. She contended that the officer’s purpose was merely to verify whether the bag she was carrying was the same one he had illegally inspected, and that the evidence obtained should be suppressed.

• Invalid Warrantless Arrest: She maintained there was no probable cause for her arrest because the officer had no personal knowledge of an offense she had committed; she was merely carrying bags at someone’s behest.

• Failure to Establish Corpus Delicti and Chain of Custody: Mariacos claimed that the prosecution failed to prove the corpus delicti because the apprehending officers violated Dangerous Drugs Board Regulation No. 3, Series of 1979, as amended, and Section 21 of R.A. No. 9165. The drugs were not physically inventoried and photographed in her presence or in the presence of her counsel, a media representative, and a DOJ representative immediately after seizure. She asserted this cast serious doubt on the identity of the items and the chain of custody.

• Validity of Search under the Moving Vehicle Exception: The OSG countered that the warrantless search was a lawful search of a moving vehicle, an established exception to the warrant requirement. PO2 Pallayoc had probable cause based on reliable information from a confidential agent, confirmed by his own observation when he peeked into the bags and detected the distinct odor and appearance of marijuana.

• Waiver of Objection to Arrest: The OSG argued that Mariacos was estopped from questioning the legality of her arrest because she voluntarily entered a plea of “not guilty,” participated fully in the trial, and presented her own evidence without moving to quash the information before arraignment.

• Substantial Compliance with Custody Procedure: The OSG brushed aside the alleged procedural lapses, positing that physical inventory could be done at the nearest police station, which was done in the presence of the Mayor, and that any non‑compliance with Section 21 did not affect the admissibility of the seized drugs so long as the integrity of the evidence was maintained.

• Validity of Warrantless Search: Whether the warrantless search of the backpack aboard a moving passenger jeepney violated the constitutional prohibition against unreasonable searches and seizures.

• Validity of Warrantless Arrest: Whether the subsequent warrantless arrest of Mariacos was lawful.

• Corpus Delicti and Chain of Custody: Whether the failure to strictly comply with the inventory and photographing requirements of Section 21 of R.A. No. 9165 rendered the seized marijuana inadmissible and thus amounted to a failure to prove the corpus delicti.

• Validity of Warrantless Search: The warrantless search was held valid as a search of a moving vehicle. The moving‑vehicle exception permits a warrantless search when probable cause exists and the vehicle’s inherent mobility renders obtaining a warrant impracticable. Probable cause was founded on the specific tip from the Barangay Intelligence Network agent describing the bags, particularly the backpack with the “O.K.” marking, and PO2 Pallayoc’s personal observation of marijuana bricks upon peeking inside. The exigency was clear: the jeepney was about to leave and was in fact already in transit. The search being lawful, the seizure of the marijuana did not offend Section 2, Article III of the Constitution, and the evidence was admissible.

• Validity of Warrantless Arrest: The warrantless arrest was likewise valid. Since the search was constitutionally permissible, and PO2 Pallayoc personally witnessed Mariacos carrying the bags containing marijuana — an act constituting transportation of a dangerous drug — the arrest fell squarely under paragraph (a), Section 5, Rule 113 of the Rules of Court (arrest in flagrante delicto). A search substantially contemporaneous with an arrest may precede the arrest if probable cause existed at the outset, as it did here. Ownership of the drugs is immaterial; transportation of a dangerous drug without legal authority is a malum prohibitum offense, and Mariacos’s lack of knowledge and her claim that the bags belonged to another were insufficient to exonerate her. The disputable presumption that a person found in possession of a thing is the owner was not rebutted by her uncorroborated testimony.

• Corpus Delicti and Chain of Custody: The prosecution sufficiently established the corpus delicti despite non‑compliance with Section 21 of R.A. No. 9165. While it was admitted that no photographs were taken and no media, DOJ, or counsel representatives were present, non‑compliance with the procedural requirements under Section 21 is not fatal so long as the integrity and evidentiary value of the seized items are preserved. PO2 Pallayoc’s testimony traced the chain of custody from the moment of seizure, through the immediate transport to the station, the opening of the bags in the presence of the Mayor and Mariacos, the marking by the officers, and the submission to the crime laboratory. Mariacos did not question the custody and disposition of the items during trial, thereby waiving any objection. The police actions also carried the presumption of regularity. The dangerous drug — the very corpus delicti — was positively identified and proven to be the same substance seized from Mariacos.

• Moving‑Vehicle Exception to the Warrant Requirement — A warrantless search of a moving vehicle is valid when the searching officer has reasonable or probable cause to believe, before the search, that the vehicle contains evidence of a crime. The doctrine rests on the inherent mobility of motor vehicles, which makes it impracticable to obtain a judicial warrant before the vehicle can leave the locality or jurisdiction. Here, PO2 Pallayoc had probable cause from the intelligence agent’s tip and his own visual confirmation; the jeepney was in motion, and requiring a warrant would have defeated the seizure.

• Probable Cause for Warrantless Search — Probable cause exists when there is a reasonable ground of suspicion supported by circumstances sufficiently strong in themselves to induce a cautious man to believe that an offense has been committed and that the items sought are in the place to be searched. The tip, corroborated by the officer’s observation of the distinctive appearance of marijuana bricks, satisfied this standard.

• Search Incident to a Lawful Arrest May Precede the Arrest — A search that is substantially contemporaneous with an arrest can precede the formal arrest if the police already possess probable cause to make the arrest at the inception of the search. Thus, the warrantless inspection of the bag and the subsequent warrantless arrest of Mariacos were inextricably linked and mutually reinforcing.

• Malum Prohibitum Nature of Dangerous Drugs Offenses — Violations of the Dangerous Drugs Act, including the transportation of prohibited drugs, are mala prohibita. Ownership of the drugs is immaterial; mere possession or conveyance without legal authority constitutes the crime. Lack of criminal intent or knowledge of the nature of the substances is not a defense.

• Disputable Presumption of Ownership from Possession — Under Rule 131, Section 3(j) of the Rules of Court, a person found in possession of a thing taken in the doing of a recent wrongful act is presumed to be the taker and doer of the whole act. Mariacos failed to overcome this presumption.

• Non‑Compliance with Section 21 of R.A. No. 9165 is Not Fatal — The failure to photograph the seized drugs or to have media and DOJ representatives present during inventory does not automatically render the seizure void or the evidence inadmissible. What is of utmost importance is the preservation of the integrity and evidentiary value of the seized items. The accused’s failure to question the custody and disposition during trial constitutes a waiver of any objection.

• “The search of a moving vehicle is one of the doctrinally accepted exceptions to the Constitutional mandate that no search or seizure shall be made except by virtue of a warrant issued by a judge after personally determining the existence of probable cause.” — This passage encapsulates the controlling doctrine on which the warrantless search was upheld.

• “Without probable cause, the articles seized cannot be admitted in evidence against the person arrested.” — The Court underscored that the moving‑vehicle exception does not give police unlimited discretion; probable cause remains indispensable.

• “When an accused is charged with illegal possession or transportation of prohibited drugs, the ownership thereof is immaterial. Consequently, proof of ownership of the confiscated marijuana is not necessary.” — The Court affirmed the absolute character of drug‑related offenses.

• “Anti‑narcotics laws, like anti‑gambling laws, are regulatory statutes. … Laws defining crimes mala prohibita condemn behavior directed not against particular individuals, but against public order.” — This explains why good faith or ignorance of the contents is no defense.

• “Non‑compliance with Section 21 is not fatal and will not render an accused’s arrest illegal, or make the items seized inadmissible. What is of utmost importance is the preservation of the integrity and evidentiary value of the seized items.” — The decisive principle governing procedural lapses in the custody of dangerous drugs.

• People v. Bagista, G.R. No. 86218, 214 SCRA 63 (1992) — Cited as authority for the moving‑vehicle exception and the requirement that officers must have reasonable or probable cause before conducting a warrantless search of a moving vehicle. The Court reiterated the rationale that vehicle mobility makes obtaining a warrant impracticable.

• People v. Aruta, 351 Phil. 868 (1998) — Enumerated the recognized exceptions to the warrant requirement, including the moving‑vehicle exception, and defined probable cause; relied upon to frame the legal parameters of the search.

• People v. Del Mundo, 418 Phil. 740 (2001) — Applied for the propositions that ownership of prohibited drugs is immaterial in prosecutions for illegal possession or transportation, and that these offenses are mala prohibita.

• People v. Concepcion, G.R. No. 178876, 556 SCRA 421 (2008) — Followed for the rule that non‑compliance with Section 21 of R.A. No. 9165 is not fatal if the integrity and evidentiary value of the seized drugs are preserved.

• Article III, Section 2, 1987 Constitution — The right against unreasonable searches and seizures and the warrant requirement. The Court used the moving‑vehicle exception to hold that the warrantless search did not violate this provision.

• Section 5, Article II, Republic Act No. 9165 (Comprehensive Dangerous Drugs Act of 2002) — Defines and penalizes the sale, trading, administration, dispensation, delivery, distribution, and transportation of dangerous drugs. Mariacos was convicted under this provision for transporting marijuana.

• Section 21, Republic Act No. 9165 and its Implementing Rules and Regulations — Prescribes the procedure for custody and disposition of seized dangerous drugs, including the requirement of physical inventory and photographing in the presence of the accused, media, DOJ, and an elected official. The Court held that substantial compliance suffices when the integrity of the evidence is preserved.

• Section 13, Rule 126, Rules of Court (Search incident to lawful arrest) — Allows a person lawfully arrested to be searched for dangerous weapons or evidence without a search warrant. The Court observed that the contemporaneous search rule was satisfied.

• Section 5, Rule 113, Rules of Court (Arrest without warrant; when lawful) — Authorizes warrantless arrest when the offense is committed in the officer’s presence. The arrest of Mariacos was upheld under paragraph (a).

• Section 3(j), Rule 131, Rules of Court (Disputable presumptions) — Applied to impute ownership of the seized marijuana to Mariacos because she was found in possession at the time of arrest.

Associate Justice Antonio T. Carpio (Chairperson), Associate Justice Diosdado M. Peralta, Associate Justice Roberto A. Abad, and Associate Justice Jose Portugal Perez (additional member in lieu of Associate Justice Jose Catral Mendoza) concurred.
