G.R. No. 136731, January 18, 2001
The People of the Philippines, plaintiff-appellee, vs. Cesar Robles y Combate, accused-appellant.

FACTS

Accused-appellant Cesar Robles was convicted of Murder by the Regional Trial Court for the fatal stabbing of Antonio Lumbera on April 4, 1987, in Lipa City. The prosecution primarily relied on the testimony of Naxinsino Lumbera, the victim’s nephew, who claimed he witnessed the incident from four meters away. He testified that Robles stabbed the victim once in the right chest with a balisong. Notably, Naxinsino did not report the incident to the police for ten years, explaining he was afraid, though no evidence of threats was presented.
The defense presented an alibi, with Robles testifying he was mining in Labo, Camarines Norte, at the time of the crime, a travel distance of about one day from Lipa. The defense also highlighted a significant inconsistency: the attending physician, Dr. Nemesio Villa, testified based on medical records that the victim died from two fatal stab wounds—one on the left chest wall and another at the back—contradicting the eyewitness’s account of a single wound to the right chest.

ISSUE

The core issue is whether the prosecution proved the guilt of the accused-appellant beyond reasonable doubt.

RULING

The Supreme Court REVERSED the conviction and ACQUITTED accused-appellant Cesar Robles on the ground of reasonable doubt. The legal logic centered on the failure of the prosecution evidence to meet the stringent standard of proof beyond reasonable doubt.
First, the Court found the eyewitness testimony of Naxinsino Lumbera unreliable. His ten-year delay in reporting the incident, unsupported by concrete evidence of a threat, cast serious doubt on his credibility. While fear can justify delay, the justification was weak here. More critically, his testimony was materially inconsistent with the physical evidence. He described a single stab to the right chest, but the medical evidence established two fatal wounds in different locations (left chest and back). This irreconcilable contradiction between the lone eyewitness account and the objective medical findings destroyed the reliability of the prosecution’s narrative of the crime.
Second, the defense of alibi, while weak and uncorroborated, did not need to be persuasive because the burden of proof remained with the prosecution. The prosecution’s case collapsed due to its own internal inconsistencies. The Court emphasized that a conviction cannot rest on a strong suspicion or probability of guilt. The evidence must establish guilt to a moral certainty, with the hypothesis of guilt flowing naturally from all the facts proved. Here, the discrepancy between the eyewitness testimony and the medico-legal evidence created reasonable doubt as to the identity of the perpetrator and the actual events. Consequently, the accused was entitled to an acquittal.
