G.R. No. 111523 August 10, 1994
PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. ROEL PONAYO Y VILLANUEVA, accused-appellant.

FACTS

Accused-appellant Roel Ponayo was convicted of murder for the fatal stabbing of Rolando Gaza. The prosecution evidence established that in the early morning of January 26, 1991, the victim was walking home with companions, including witnesses Leny Cao and Rodel Labag, after attending a dance. Without any provocation, Ponayo approached from behind and suddenly stabbed Gaza, who then fled but was pursued. Gaza was later found dead.
The defense interposed self-defense. On appeal, Ponayo challenged the credibility of the prosecution witnesses due to alleged inconsistencies in their testimonies and affidavits. He also argued that treachery was not proven and that the trial court erred in not appreciating the mitigating circumstance of voluntary surrender.

ISSUE

The core issues were: (1) the credibility of the prosecution witnesses; (2) the presence of treachery; (3) the validity of the claim of self-defense; and (4) the applicability of voluntary surrender as a mitigating circumstance.

RULING

The Supreme Court affirmed the conviction but modified the penalty. The alleged inconsistencies in the witnesses’ testimonies—such as whether Cao immediately reported the incident or went home first, and the precise positions of the individuals in the group—were deemed minor, trivial, and inconsequential. The Court held that such variances, especially between an affidavit and courtroom testimony, do not impair credibility but may instead indicate truthfulness, as they negate any suspicion of rehearsed testimony.
Treachery (alevosia) was correctly established. The attack was sudden, from behind, and without warning, while the victim was unarmed and walking peacefully with friends. This method of attack ensured the execution of the crime without risk to the assailant from any defense the victim might make, satisfying the legal definition of treachery.
The claim of self-defense failed. For self-defense to be valid, unlawful aggression by the victim is an indispensable element. The evidence clearly showed that the victim initiated no aggression; the attack was entirely sudden and unprovoked. With no unlawful aggression present, self-defense cannot prosper.
The Court, however, agreed with the Solicitor General that the mitigating circumstance of voluntary surrender should be appreciated. The testimony of the Chief of Police confirmed that Ponayo, accompanied by his aunt, surrendered himself to the police a few hours after the incident without being arrested or compelled. This act met all legal requisites for voluntary surrender.
Consequently, with the presence of this mitigating circumstance and applying the Indeterminate Sentence Law, the penalty was reduced. Ponayo was sentenced to an indeterminate penalty of ten (10) years and one (1) day of prision mayor, as minimum, to seventeen (17) years, four (4) months, and one (1) day of reclusion temporal, as maximum. The civil indemnity was affirmed.
