G.R. No. 71838 February 26, 1990
THE PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. LAMBERTO BORJA Y MARTINEZ, defendant-appellant.

FACTS

Accused-appellant Lamberto Borja y Martinez was convicted by the Regional Trial Court of Manila for violating the Dangerous Drugs Act ( R.A. No. 6425 ) and sentenced to reclusion perpetua. The prosecution evidence established that on June 26, 1984, acting on a tip from a barangay chairman, police officers conducted a buy-bust operation. Patrolman Bernardo Estamo, acting as poseur-buyer, approached Borja (alias “Totong”) and bought five sticks of marijuana cigarettes for ten pesos. Upon Estamo’s pre-arranged signal, backup officers arrested Borja, recovering the marked money from him. A consented search of his house yielded an additional fifty-five sticks of marijuana. Forensic examination confirmed all seized items were marijuana.
The defense presented a starkly different narrative. Borja claimed he was at home with his children when policemen suddenly grabbed him, beat him, and forced him to sign the confiscated marijuana cigarettes, the marked money, and a “Consent to Search” document. He alleged the evidence was planted and his confession was coerced. His sister and a neighbor corroborated his claim of being framed.

ISSUE

The core issues were: (1) whether the buy-bust operation constituted illegal instigation or a valid entrapment; and (2) whether the prosecution proved Borja’s guilt beyond reasonable doubt.

RULING

The Supreme Court affirmed the conviction. On the first issue, the Court distinguished entrapment from instigation. Entrapment, which is legal, involves ways and means to trap a criminal already engaged in illegal activity. Instigation, which is illegal, implants the criminal design in the mind of the accused. The Court found the operation was a valid entrapment. The police acted on a tip that Borja was already selling marijuana; the poseur-buyer merely presented himself as a buyer without inducing Borja to commit a crime he would not have otherwise committed. The defense of frame-up was rejected for being inherently weak and uncorroborated by clear and convincing evidence, especially against the presumption of regularity in the performance of official duty by the arresting officers.
On the second issue, the Court held that the prosecution successfully proved all elements of the crime. The testimonies of the poseur-buyer and the apprehending officers were credible, consistent, and constituted direct evidence of the sale. The forensic chemist’s testimony and report, afforded the presumption of regularity, confirmed the nature of the drugs. The defense’s attack on the scientific procedure was deemed insufficient, as the defense counsel, during cross-examination, did not compel the chemist to detail the specific laboratory methods, focusing instead on bureaucratic chain-of-custody aspects. The positive identification and the seized corpus delicti established guilt beyond reasonable doubt.
