327 Cases Penned by Associate Justice Amy Lazaro-Javier: 2025 Bar Examination
Can the killing of an individual, who allegedly attacked
first, be justified as self-defense when the accused failed to provide credible
evidence of unlawful aggression?
Case Title:
People of the Philippines vs. Jomar Doca y Villaluna
G.R. No. 233479 | October 16, 2019
Facts of the Case:
In this case, Jomar Doca y Villaluna was charged with the
murder of Roger C. Celestino, a 17-year-old boy, on July 1, 2007, in Solana,
Cagayan. Doca allegedly stabbed Roger in the chest using a Rambo knife,
resulting in his immediate death. According to witness testimonies, Doca had
been drunk and was waiting for Roger at a waiting shed. When Roger passed by,
Doca suddenly stabbed him without provocation.
The defense argued that Doca acted in self-defense. He
claimed that Roger attacked him first by boxing him and pulling out a fan knife
(balisong). Doca allegedly managed to disarm Roger and used the knife to stab
him in self-defense. He then fled the scene and surrendered to the authorities
the next day.
The trial court found Doca guilty of murder, rejecting his
plea of self-defense and appreciating the qualifying circumstance of treachery.
Doca was sentenced to reclusion perpetua. The Court of Appeals affirmed
the conviction but adjusted the damages awarded to the victim's family.
Primary Issue in the Supreme Court:
Did the Court of Appeals err in affirming Jomar Doca’s
conviction for murder despite his claim of self-defense?
Supreme Court Ruling:
The Supreme Court ruled that Jomar Doca failed to prove that
he acted in self-defense. In cases of self-defense, the burden of proof lies on
the accused, who must present clear and convincing evidence of unlawful
aggression by the victim. Doca’s claim was solely based on his testimony, which
was uncorroborated and self-serving. Moreover, the prosecution's evidence
showed that Roger was unarmed and posed no immediate threat when he was
stabbed. As a result, Doca’s claim of self-defense was dismissed.
However, the Supreme Court found that treachery, which
qualified the killing to murder, was not present. It ruled that while the
attack was sudden, Roger was aware of the impending danger, as Doca had been
visibly angry and armed. As there was no evidence of evident premeditation or
deliberate intent to kill without risk to the assailant, the Court downgraded
the crime to homicide. The mitigating circumstance of voluntary
surrender was appreciated, and Doca’s sentence was reduced to an indeterminate
penalty of 8 years of prision mayor as minimum to 12 years and 6 months of
reclusion temporal as maximum.
Dispositive Portion:
"ACCORDINGLY, the appeal is PARTLY GRANTED. Appellant
JOMAR DOCA y VILLALUNA is found guilty of HOMICIDE. He is sentenced to the
indeterminate penalty of eight (8) years of prision mayor as minimum to twelve
(12) years and six (6) months of reclusion temporal as maximum. He is further
required to pay P50,000.00 as civil indemnity, P50,000.00 as moral damages, and
P50,000.00 as temperate damages. These amounts shall earn six percent (6%)
interest per annum from finality of this decision until fully paid."
In situations where the accused invokes self-defense, how
can the burden of proof impact the outcome, especially when evidence is solely
based on their testimony?

of Proof in Self-Defense:

Circumstance of Voluntary Surrender:
“Voluntary surrender requires spontaneity and the accused's intent to surrender without being forced or arrested.” — This doctrine explains how surrender can mitigate the sentence imposed on an accused, provided it is proven that the surrender was voluntary and spontaneous.
Classification:

📚 10 IMPORTANT DOCTRINES
FROM THE CASE
- Burden
of Proof in Self-Defense:
Once self-defense is invoked, the burden shifts to the accused to prove unlawful aggression. (Source: SC Decision, p. 25) - Unlawful
Aggression is Indispensable:
Without clear proof of unlawful aggression by the victim, self-defense cannot be appreciated. (Source: p. 27) - Suddenness
≠ Treachery:
Not all sudden attacks qualify as treacherous. The offender must consciously adopt a method that eliminates risk to himself. (Source: pp. 32–33) - Single
Eyewitness Testimony May Suffice:
The Court upheld the credibility of one eyewitness whose direct and consistent testimony proved the killing. (Source: p. 29) - Self-Serving
Testimony is Weak:
An uncorroborated, self-serving claim of self-defense holds little weight. (Source: p. 28) - Treachery
Requires Deliberate Method:
The accused must deliberately adopt a mode to ensure execution of the crime without risk to himself. (Source: p. 33) - Voluntary
Surrender as Mitigating Circumstance:
To be appreciated, the surrender must be spontaneous and to a person of authority. (Source: p. 37) - Reclusion
Perpetua is Indivisible:
Even with mitigating circumstances, courts cannot lower reclusion perpetua unless the charge is downgraded. (Source: p. 37) - Murder
vs. Homicide – Difference in Qualifying Circumstance:
Murder requires treachery, evident premeditation, etc. Without them, only homicide may be charged. (Source: p. 25) - Interest
on Damages:
Monetary awards must earn 6% legal interest per annum from finality until fully paid. (Source: p. 41)
