Case Summary (G.R. No. 235898)

Factual Background

Marlon Dominguez y Argana was charged with illegal possession of a dangerous drug after police officers alleged that at about 2:00 a.m. on August 17, 2010, SPO1 Gerardo Parchaso saw him standing in a small, lighted alley near Argana Street holding a very small transparent plastic sachet. SPO1 Parchaso testified that from a distance of about one meter he saw the sachet, grabbed Dominguez, arrested him, and seized the sachet. The seized item was marked with the initials “MD,” inventoried at the police station, and submitted to the PNP-Southern Police District Crime Laboratory, which issued a report finding that the specimen weighing 0.03 gram yielded a positive result for shabu.

Prosecution’s Version

The prosecution presented SPO1 Parchaso, who testified that he was conducting monitoring for RA 9165 violations at Purok 3, Barangay Poblacion, Muntinlupa City, when he observed Dominguez holding a small sachet and immediately arrested him. PO2 Salvador Genova assisted, and the arrested person and the seized sachet were brought to the police station. The prosecution described inventory and marking procedures, identified witnesses to the inventory, and introduced the laboratory report by Police Chief Inspector Abraham Verde Tecson confirming the presence of methamphetamine hydrochloride in the seized specimen.

Defense’s Version

Marlon Dominguez y Argana denied the allegations and testified that two men in civilian clothes entered his home at around 11:00 p.m. on August 16, 2010, grabbed and arrested him, placed him in a white Toyota Revo, and brought him to the police station where police officers showed him a sachet and urged him to “settle” the matter. His wife, Rowelyn, corroborated that two men identifying themselves as police officers barged into their home, that one man struck Dominguez, and that they were asked for P50,000. The defense emphasized claims of physical abuse, extortion, and a frame-up.

Proceedings Below

After arraignment and trial, the RTC found the prosecution had proven the elements of illegal possession and preserved the chain of custody, and it convicted Dominguez on March 22, 2016, sentencing him to imprisonment and a fine. Dominguez appealed to the Court of Appeals. The CA, in a Decision dated May 9, 2017, affirmed the RTC, reasoning that Dominguez was caught in flagrante delicto holding the sachet, that he was positively identified by SPO1 Parchaso, that laboratory analysis confirmed shabu, and that the chain of custody was intact.

Issue Presented

The sole issue for the Supreme Court’s resolution was whether the RTC and the CA erred in convicting Dominguez, particularly whether the warrantless arrest and the attendant search and seizure were lawful and whether the seized sachet was admissible evidence.

Ruling of the Supreme Court

The Supreme Court granted the petition, reversed and set aside the Court of Appeals Decision, and acquitted Marlon Dominguez y Argana on the ground of reasonable doubt. The Court ordered his immediate release unless lawfully held for another cause and directed implementation measures for his release.

Legal Reasoning

The Court held that although failure to object to an illegal arrest before arraignment waives objection to the court’s acquisition of jurisdiction over the person, such waiver does not extend to the admissibility of evidence seized during an illegal warrantless arrest, citing Homar v. People. The constitutional protection against unreasonable searches and seizures under Art. III, Sec. 2 of the 1987 Constitution and the exclusionary rule under Sec. 3(2), Art. III were applied. The Court examined the exceptions to the warrant requirement and analyzed whether the facts justified a warrantless search incident to a lawful arrest or a seizure under the plain view doctrine.

Application of the Law to the Facts

The Court found that the prosecution failed to establish the requisites for a lawful warrantless arrest under Section 5, Rule 113. The testimony of SPO1 Parchaso showed only that he saw a man holding a very small plastic sachet at about one meter distance and thereafter arrested him. The Court concluded that merely standing on the street and holding a small sachet did not constitute an overt act indicating that the person had just committed, was committing, or was attempting to commit an offense, nor did the circumstances make it immediately apparent to the officer that the sachet contained contraband. The Court relied on its prior decisions, including People v. Villareal and Comerciante v. People, to hold that identification of a minute quantity of substance in a small sachet from a distance is insufficient to create probable cause for an arrest or to qual
