G.R. No. L-72564 April 15, 1988
PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. ANITA CLAUDIO Y BAGTANG, accused-appellant.

FACTS

Accused-appellant Anita Claudio was charged with violating the Dangerous Drugs Act for transporting 1.1 kilos of marijuana from Baguio City to Olongapo City on July 21, 1981. The prosecution evidence established that Pat. Daniel Obiña, a policeman assigned to the Anti-Narcotics Unit, was on the same Victory Liner bus. He observed Claudio board the bus and place a woven buri bag behind his seat, an act that aroused his suspicion. At a stop in San Fernando, Pampanga, Obiña inspected the bag, inserting a finger into a plastic bag inside it and detecting the smell of marijuana. Upon arrival in Olongapo, after Claudio alighted, Obiña intercepted her, identified himself, and informed her he would search her bag. He then arrested her and brought her to the police headquarters where the bag was opened in the presence of investigators, revealing a bundle of marijuana leaves. A forensic chemist confirmed the substance was marijuana.
At trial, Claudio presented an alibi, testifying she was not on the bus from Baguio but was in Olongapo City the entire time, and claimed she was arrested without cause. She alternatively argued in her appeal that if found with the drugs, she should only be liable for possession, not transportation, and later claimed the evidence was fabricated and the marijuana was planted.

ISSUE

The core issues were: (1) whether the warrantless arrest and subsequent search were lawful; (2) whether the crime of illegal transportation of marijuana was proven beyond reasonable doubt; and (3) whether the defense of alibi and claims of evidence fabrication should prevail.

RULING

The Supreme Court affirmed the conviction. The warrantless arrest was lawful as Claudio was caught in flagrante delicto committing the offense of transporting prohibited drugs. Under Rule 113, Section 5(a) of the 1985 Rules on Criminal Procedure, a peace officer may arrest a person without a warrant when the person is caught actually committing an offense. The search of her bag was a valid incident to that lawful arrest under Rule 126, Section 12, allowing a search for evidence of the crime. Therefore, the seizure of the marijuana was legal.
On the merits, the Court found the prosecution evidence conclusive. The positive identification by Pat. Obiña, corroborated by other police witnesses and physical evidence like the bus ticket and chemistry report, firmly established that Claudio transported the marijuana. Her possession of such a large quantity, over one kilo, indicated an intent to sell or distribute, supporting the charge of transportation. Her alibi, uncorroborated and established only by her own testimony, could not prevail over the positive and credible testimonies of the prosecution witnesses. The Court upheld the presumption that the police officers regularly performed their duty and found no motive for them to fabricate charges. Thus, guilt was proven beyond reasonable doubt, and the penalty of reclusion perpetua and a fine were sustained.
