G.R. No. 92509 - People vs. Gadiana

On March 19, 1988, during the barangay fiesta in Barangay Lutoban, Zamboanguita, Negros Oriental, Constantino Paltinca, along with others, was conversing near a sari-sari store.
Tomas Gadiana, the accused, attended the fiesta and became involved in the incident with Paltinca.

During the event, Gadiana allegedly approached Paltinca from behind while the latter was leaning against a coconut tree.
Gadiana stabbed Paltinca with a 6-inch hunting knife on the left side of his abdomen.
Despite a brief chase by the victim—who, after being stabbed, skipped about ten (10) meters before collapsing—Paltinca sustained fatal injuries.
Medical examination and autopsy revealed that the single stab wound was 5 cm long, penetrated the abdominal cavity, perforated the liver and gall bladder, transected the jejunum, and resulted in general peritonitis, hemoperitoneum, and irreversible shock, leading to the victim’s death around 10:00 o’clock that evening.

Two key prosecuting witnesses, Juan Rafal and Temistocles Gajelloma, provided accounts that varied in details:

Rafal testified that after the stabbing, Paltinca chased Gadiana for about ten meters before collapsing.
Gajelloma, however, testified that Paltinca did not chase his assailant because his intestines were exposed, and he was carried by his mother to the hospital.

The precise location of the wound – Rafal noted a stab on the left side below the ribs, whereas Gajelloma mentioned a hit on the right side.
The victim's posture – Rafal claimed that Paltinca’s right hand was holding the trunk of a coconut tree, whereas Gajelloma stated he was leaning against the tree with his right hand behind his head.
The presence or absence of any utterance by Gadiana before the attack, with Rafal asserting silence and Gajelloma testifying that Gadiana exclaimed, “This is yours.”

Gadiana admitted to stabbing Constantino Paltinca but claimed his actions were in self-defense.
According to Gadiana’s account:

Paltinca, whom he knew as “Cristino,” first held him up, demanded money, and threatened to kill him.
While attempting to escape, Paltinca allegedly blocked Gadiana’s way with a hunting knife, leading Gadiana to kick him, which caused Paltinca to lose his knife.
Gadiana then swiftly picked up the victim’s knife and stabbed him.

The Regional Trial Court, Branch 34, Dumaguete City, convicted Gadiana of murder on January 31, 1990, sentencing him to reclusion perpetua and ordering him to indemnify the victim’s heirs initially to the amount of ₱30,000.
On appeal, Gadiana contended that the prosecution’s evidence did not meet the test of moral certainty and argued that inconsistencies among witness testimonies should have led to his acquittal.
The court examined whether any material facts were unappreciated and whether the differences in witness testimony concerning the sequence and specifics of events materially weakened the prosecution’s case.

Whether the evidence presented by the prosecution met the test of moral certainty to override the constitutional presumption of innocence.
Whether the “grave and irreconcilable inconsistencies” in the testimonies of the prosecution witnesses are sufficient to undermine the overall credibility of the evidence.
Whether the discrepancies in the details recounted by the witnesses (regarding the direction of the stab, the victim’s movements, and the utterance by the accused) have a material bearing on Gadiana’s guilt.
Whether the self-defense claim is substantiated by the facts, particularly considering whether Paltinca’s actions could justify the accused’s lethal response.
Whether the lack of an established motive in the prosecution’s case should render the conviction for murder invalid, despite positive identification and the accused’s own confession.
