G.R. No. 131835 February 3, 2000
PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. ARNULFO QUILATON alias “ARNOLD,” PATRICIO QUIYO, DIDING MAMALINGPING, AVELINO AHAO y LATIMBANG, HILDO BUACON y EMPONG, accused; ARNULFO QUILATON alias “ARNOLD,” appellant.

FACTS

On August 9, 1980, in Magpet, North Cotabato, a violent attack occurred in the house of Arturo Laus. Arturo Laus and Pio de Juan were killed, while Jerry de Juan, Arnel Laus, and Carlito Taping were seriously injured. The prosecution’s eyewitness, Erlinda Taping, testified that she saw accused Hildo Buacon hack and shoot her husband Carlito, and that Buacon, along with Patricio Quiyo and Diding Mamalingping, fled after the incident. When she went downstairs, she discovered the bodies and the other wounded victims. The prosecution’s case against appellant Arnulfo Quilaton, a 16-year-old houseboy present that night, rested primarily on the testimony of Carlito Taping, who stated he saw Quilaton come out from under a bed after the attack.
The defense maintained Quilaton’s innocence, arguing he was merely a sleeping occupant and a minor laborer in the house. He denied any participation in the conspiracy. The trial court convicted Quilaton of double murder and triple frustrated murder, sentencing him to reclusion perpetua. Quilaton appealed, arguing the prosecution failed to prove his guilt beyond reasonable doubt.

ISSUE

Whether the prosecution proved the guilt of appellant Arnulfo Quilaton beyond reasonable doubt, specifically his alleged conspiracy in the crimes.

RULING

No. The Supreme Court reversed the conviction and acquitted Arnulfo Quilaton. The Court emphasized that the burden of proof lies with the prosecution to establish guilt beyond reasonable doubt, and the constitutional presumption of innocence must prevail unless this burden is discharged. The evidence against Quilaton was insufficient to prove conspiracy. The lone testimony of Carlito Taping, that he saw Quilaton emerge from under a bed after the attack, merely established Quilaton’s presence at the scene. Mere presence, without any clear, overt act demonstrating a common criminal purpose or agreement with the principal assailants, is not enough to establish conspiracy. The prosecution did not present evidence that Quilaton performed any act of execution, instigated the attack, or cooperated in its commission. His act of paying for a victim’s hospitalization was ambiguous and did not conclusively indicate guilt. Without proof of concerted action, Quilaton’s passive presence could not sustain a finding of criminal liability. The Court ruled that the prosecution failed to overcome the presumption of innocence, warranting acquittal on reasonable doubt.
