G.R. No. 73006. September 29, 1989.
PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. LEONARDO PERIODICA, JR., accused-appellant.

FACTS

On January 1, 1983, accused-appellant Leonardo Periodica, Jr., and his co-accused Parut Villarin were arrested in Paete, Laguna, for allegedly violating the Dangerous Drugs Act. The prosecution’s case established that the two bartered 50 pieces of marijuana leaves for a .45 caliber pistol on a hill in Paete. The transaction was witnessed by two PC officers, C2C Filemon Togado and Pat. Juanito Damayo, who were positioned about 50 meters away. They observed a PC informant hand the pistol to Periodica and receive a box in return. Periodica was later apprehended in the lowland by other officers, with the pistol found in his possession. The box was turned over to the PC Crime Laboratory, where a forensic chemist confirmed its contents to be marijuana leaves.
The defense presented Periodica and his mother. Periodica denied the barter, claiming Villarin merely entrusted the pistol to him during a drinking spree. His mother testified only to his good character and arrest. No other witnesses, including Villarin or the alleged drinking companions, corroborated Periodica’s account. The trial court convicted Periodica of drug trafficking and sentenced him to life imprisonment and a fine.

ISSUE

Whether the trial court erred in convicting Periodica based on the prosecution’s evidence, despite the defense’s claims of insufficient proof, inconsistencies in testimonies, alleged instigation, and an invalid extrajudicial confession.

RULING

The Supreme Court affirmed the conviction. The Court held that the alleged minor inconsistencies in the testimonies of the prosecution witnesses did not affect their core credibility regarding the consummated barter. The evaluation of witness credibility is primarily for the trial judge, who observes their demeanor, and such findings are accorded great respect absent a clear showing of error. The Court found no improper motive for the government agents, who were performing their duty in an anti-drug operation.
The defense’s claim of instigation, rather than lawful entrapment, was rejected. The Court distinguished entrapment, where the criminal intent originates from the accused, from instigation, where law enforcers induce the commission of a crime. The evidence showed Periodica and Villarin had been under surveillance and themselves initiated the idea of bartering drugs for a firearm; the operatives merely provided the opportunity to apprehend them in the act. This constituted valid entrapment.
Regarding the extrajudicial confession allegedly obtained through force and without counsel, the Court noted its invalidity due to the absence of a valid waiver of the right to counsel. However, this did not undermine the conviction, as the trial court’s decision did not rely on this confession. The conviction was firmly based on the direct, credible, and corroborated testimonies of the prosecution witnesses and the physical evidence, which Periodica failed to rebut. The government’s evidence thus proved his guilt beyond reasonable doubt.
