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, as presented by PC operatives, was that Periodica and Villarin bartered 50 pieces of marijuana leaves for a .45 caliber pistol with a PC informant on a hill. Two prosecution witnesses, C2C Filemon Togado and Pat. Juanito Damayo, claimed to have observed the transaction from about 50 meters away. After the exchange, the informant handed over the box containing the leaves to the authorities, which were later confirmed by a forensic chemist to be marijuana. Periodica was apprehended in the lowland with the pistol in his possession, while Villarin escaped.
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. The defense moved to dismiss, arguing the crime of drug trafficking was not proven and that at most, Periodica could only be liable for illegal possession of a firearm. The trial court denied the motion, convicted Periodica, and sentenced him to life imprisonment and a fine.

ISSUE

Whether the trial court erred in convicting Periodica based on the evidence presented by the prosecution.

RULING

The Supreme Court affirmed the conviction. The Court held that the minor inconsistencies in the testimonies of the prosecution witnesses did not affect their overall credibility, as such discrepancies are expected and do not undermine the core narrative of the crime. The evaluation of witness credibility is primarily for the trial court, which observed their demeanor, and its findings are accorded great respect. The Court found no improper motive for the government agents, who were performing their duty in the anti-drug campaign.
The Court rejected the defense’s argument that the operation constituted instigation rather than entrapment. It distinguished the two: entrapment involves law enforcement setting a trap for a person already intending to commit a crime, while instigation involves inducing an otherwise innocent person to commit it. 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 for the entrapment. Thus, the defense of instigation failed.
Furthermore, while the Court noted that any extrajudicial confession obtained without counsel would be inadmissible, it found that the trial court’s decision did not rely on such a confession. The conviction was sustained solely on the credible testimonial and physical evidence proving the barter transaction. Periodica’s uncorroborated denial could not prevail over the positive identification by prosecution witnesses. The Court emphasized that as long as guilt is proven beyond reasonable doubt, the law on dangerous drugs must be enforced.
