G.R. No. 83325 May 8, 1990
THE PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. DANTE MARCOS y SIBAYAN, accused-appellant.

FACTS

Accused-appellant Dante Marcos y Sibayan was charged with the illegal sale and distribution of marijuana under Republic Act No. 6425 . The prosecution evidence established that on December 4, 1985, a buy-bust operation was conducted in Baguio City. Acting on a tip, a team was formed with A2C Serafin Artizona as the poseur-buyer. Artizona, accompanied by a confidential informant, met the appellant at Holy Ghost Hill Proper. After negotiations, appellant agreed to sell marijuana at P700 per kilo. Appellant left and returned with a sack containing the prohibited drug. Upon delivery and inspection of the contents, Artizona gave the pre-arranged signal, leading to appellant’s arrest. Forensic examination confirmed the substance to be marijuana weighing 9.2 kilos.
The defense presented a different version, claiming the appellant was merely a visitor at the location and was framed. The trial court found the prosecution’s evidence credible and convicted the appellant, sentencing him to life imprisonment and a fine. Appellant appealed, challenging the credibility of the prosecution witnesses and the validity of his arrest.

ISSUE

The core issue is whether the prosecution successfully proved the guilt of the accused for the illegal sale of marijuana beyond a reasonable doubt.

RULING

The Supreme Court affirmed the conviction. The legal logic centered on the essential elements of illegal sale of dangerous drugs: the identity of the buyer and seller, the object and consideration, and the delivery. The Court found all elements conclusively established through the clear, consistent, and credible testimony of the poseur-buyer, Artizona, which was corroborated by other team members. The transaction’s consummation was proven by the delivery of the marijuana to Artizona and the payment.
The Court dismissed the defense of frame-up, noting the absence of any ill motive on the part of the arresting officers, who are presumed to have performed their duties regularly. Minor inconsistencies in the testimonies of prosecution witnesses regarding non-material details, such as not knowing the house number, were deemed inconsequential and did not affect their core credibility. The trial court’s factual findings on witness credibility were accorded great weight, as it had the direct opportunity to observe demeanor. The arrest, effected during a legitimate buy-bust operation, was also deemed valid. Consequently, the judgment of the trial court was upheld.
