People vs. Casas

Self-defense cannot be appreciated where the accused was the initial aggressor and the victims did not commit unlawful aggression, and treachery cannot be presumed but must be proven by clear and convincing evidence showing deliberate adoption of means to ensure the victim had no opportunity to defend himself.

Casas was a former employee of a taho factory located at 313 F. Roman Street, San Juan City. On December 24, 2007, he went to the factory looking for a certain Jesus. The factory employees involved in the incident were Eligio Ruiz, who confronted Casas, and Joel Tabile, who attempted to help Eligio during the attack. Two criminal Informations were filed against Casas: one for the Murder of Joel and another for Frustrated Murder of Eligio, both alleged to have been committed with treachery, evident premeditation, and abuse of superior strength.

On December 24, 2007, between one and two o'clock in the afternoon, Casas, accompanied by a certain "Ron-Ron," went to a taho factory at 313 F. Roman Street, San Juan City, looking for a certain Jesus. Failing to find him, Casas brandished a knife and stuck it into a pail used for making taho. Eligio, an employee of the factory, confronted Casas, remarking on his arrogance and suggesting he simply look for the person he sought. Casas responded by offering the knife to Eligio. Eligio told Casas to get rid of the knife, which Casas handed to Ron-Ron. A fistfight then ensued between Eligio and Casas.

During the melee, Casas took the knife back from Ron-Ron and stabbed Eligio twice while Eligio was fleeing. In his continued pursuit of Eligio, Casas ran into Joel, who tried to help Eligio using a bamboo pole. Joel slipped, fell face first on the floor, and lay prostrate. Casas stabbed him twice — the first blow entering his back and exiting at the front of his torso, and the second hitting the left side of his abdomen. Casas then overtook Eligio and stabbed him again on the stomach. Fearing for his life, Eligio grabbed a plastic stool and struck Casas on the head, forcing Casas to drop the knife and cease the attack. PO1 Fuentes and PO3 Fronda encountered a bloodied Casas nearby; Casas told them he had just stabbed someone, and after confirming a stabbing incident had occurred, they arrested him.

Casas initially denied the stabbing and filed a demurrer to evidence based on alleged inconsistencies in the prosecution witnesses' testimonies, which the RTC denied on December 30, 2010. The defense then changed its theory: Casas admitted stabbing both Joel and Eligio but claimed self-defense. He testified that he was a former employee of the factory and had been asked by his former employer to collect the remainder of his salary. According to Casas, Joel challenged him to a fight and attacked him with a knife; he suffered minor injuries while disarming and stabbing Joel. He claimed Eligio and one Rolando Jaronel then attacked him, prompting him to repeatedly stab Eligio in self-defense. He maintained he did not intend to kill Joel.

The RTC found the prosecution's version more credible, concluding that Casas was the aggressor and that his injuries — three abrasions, one contusion, and five incised wounds — did not threaten his life. It convicted him of Murder for Joel's death, appreciating treachery because Joel was stabbed while lying prostrate and unable to defend himself. For Eligio's stabbing, the RTC convicted him of Attempted Homicide, finding intent to kill but no qualifying circumstances and no proof that all acts of execution were performed. The CA affirmed with modifications to the damages awarded.

• Self-Defense: Casas argued that he acted in self-defense when he stabbed Joel and Eligio, claiming that Joel initiated the attack by challenging him to a fight and attacking him with a knife, and that Eligio and Rolando Jaronel attacked him after he stabbed Joel, necessitating his repeated stabbing of Eligio to protect himself.
• Lack of Intent to Kill: Casas maintained that he did not intend to kill Joel, asserting that he merely disarmed Joel and suffered minor injuries in the process.
• Inconsistencies in Prosecution Evidence: Casas initially challenged the prosecution's evidence through a demurrer to evidence, alleging inconsistencies in the testimonies of prosecution witnesses.

• Self-Defense: Whether Casas's claim of self-defense should be sustained to absolve him of criminal liability for the stabbing of Joel and Eligio.
• Treachery: Whether treachery was sufficiently proven to qualify the killing of Joel as Murder.
• Attempted Homicide: Whether Casas's conviction for Attempted Homicide for the stabbing of Eligio should be upheld.

• Self-Defense: No. The claim of self-defense was rejected because no unlawful aggression from the victims was proven; Casas was the initial aggressor who wielded a knife and pursued fleeing victims.
• Treachery: No. Treachery was not proven because Joel was aware of the danger when he intervened and there was no showing that Casas deliberately adopted means to ensure Joel could not defend himself; the conviction was downgraded from Murder to Homicide.
• Attempted Homicide: Yes. The conviction for Attempted Homicide was affirmed, the prosecution having proven intent to kill but not all acts of execution that would consummate the homicide, nor the fatal nature of Eligio's wounds.

• Self-Defense: Upon invoking self-defense after admitting the stabbing, Casas assumed the burden of proving the justification of his act with clear and convincing evidence, relying on the strength of his own evidence rather than the weakness of the prosecution's. The first requisite of self-defense — unlawful aggression — was absent. The records showed that Casas was the aggressor: he wielded the knife, brought it to bear on Eligio, then on Joel as he lay prostrate, and again on Eligio as the latter was fleeing. The initial fistfight did not constitute unlawful aggression by Eligio because Eligio had already yielded and was fleeing when Casas stabbed him. Unlawful aggression ceases once the first aggressor runs away; to attack a retreating aggressor constitutes retaliation, not self-defense. Since the core element of unlawful aggression was not proven, the claim of self-defense failed and criminal liability attached.

• Treachery: The elements of Murder require proof of a qualifying circumstance under Article 248 of the RPC. Treachery, under Article 14, requires that the means of execution give the victim no opportunity to defend himself or retaliate, and that such means were deliberately or consciously adopted; treachery cannot be presumed but must be proven by clear and convincing evidence. The records showed that Joel was aware of the danger: he knew Casas was armed and had just stabbed Eligio, yet Joel elected to intervene and armed himself with a bamboo pole. Further, there was no showing that no appreciable interval elapsed between Joel's fall and the stabbing, or that Casas deliberately adopted means to ensure Joel could not defend himself. Casas simply stabbed Joel as Joel happened to slip and fall. Joel's awareness of the danger and the lack of deliberation by Casas negated treachery. The conviction was accordingly downgraded from Murder to Homicide under Article 249 of the RPC.

• Attempted Homicide: The RTC correctly ruled that while Casas's intent to kill Eligio was evident from the weapon used, the number of wounds inflicted, his pursuit of Eligio after the latter fled, and the body parts targeted, no qualifying circumstances for Murder were present. The crime was only in its attempted stage because the prosecution failed to prove that Casas performed all acts of execution that would consummate the homicide, and the nature of Eligio's wounds was not shown to be fatal. The CA's affirmation of this conviction was sustained.

• Unlawful Aggression as Condition Sine Qua Non of Self-Defense — Unlawful aggression is the indispensable element of self-defense; without it, the defense cannot stand. Unlawful aggression requires an actual, sudden, and unexpected attack or imminent danger thereof, not merely a threatening or intimidating attitude. In this case, Casas was the initial aggressor, and the victims did not commit unlawful aggression against him. The fistfight did not constitute unlawful aggression by Eligio because Eligio had already yielded and was fleeing when Casas stabbed him.

• Cessation of Unlawful Aggression and Retaliation — The moment the first aggressor runs away, unlawful aggression ceases to exist; when it ceases, the defender no longer has any right to kill or wound the former aggressor. To do so constitutes retaliation, not self-defense. In retaliation, the aggression begun by the injured party has already ceased when the accused attacked him, whereas in self-defense the aggression was still existing when the aggressor was injured.

• Treachery: Elements and Proof — Treachery requires: (a) the means of execution employed gives the victim no opportunity to defend himself or retaliate; and (b) the methods of execution were deliberately or consciously adopted. Treachery cannot be presumed but must be proven by clear and convincing evidence. The essence of treachery is a sudden, unexpected, and unforeseen attack without the slightest provocation on the victim's part, such that the victim must not have known the peril he was exposed to. If the victim was forewarned of the danger and met it instead of fleeing, treachery cannot be appreciated.

• Burden of Proof in Self-Defense — Upon invoking self-defense after admitting the killing, the accused assumes the burden of proving the justification of his act with clear and convincing evidence. He must rely on the strength of his own evidence, not on the weakness of the prosecution's evidence, which, even if weak, cannot be disbelieved in view of his admission.

• Formula for Loss of Earning Capacity — Net earning capacity = Life Expectancy × [Gross Annual Income − Living Expenses (50% of gross annual income)], where life expectancy = 2/3 (80 − age of the deceased). Applied to Joel, who was 22 years old with a monthly salary of ₱1,000.00 to ₱1,500.00 as a utility man, the loss of earning capacity was computed at ₱348,000.00.

• "there can be no self-defense unless the victim committed unlawful aggression against the person who resorted to self-defense." — This passage states the indispensable requirement of unlawful aggression for self-defense, the absence of which was the primary ground for rejecting Casas's defense.

• "the moment the first aggressor runs away – if and so such was the case with respect to Eligio – unlawful aggression on the part of the first aggressor ceases to exist; and when unlawful aggression ceases, the defender no longer has any right to kill or wound the former aggressor; otherwise, retaliation, and not self-defense, is committed." — This passage distinguishes retaliation from self-defense and explains why Casas's stabbing of the fleeing Eligio could not be justified.

• "treachery cannot be presumed, it must be proven by clear and convincing evidence." — This formulation states the prosecution's burden in establishing treachery as a qualifying circumstance, central to the Court's decision to downgrade Murder to Homicide.

• "Should it appear, however, that the victim was forewarned of the danger he was in, and, instead of fleeing from it he met it and was killed as a result, then the qualifying circumstance of treachery cannot be appreciated." — This passage articulates the principle that a victim's awareness of danger negates treachery, directly applied to Joel's case because he knowingly intervened while Casas was armed.

• People vs. Se, 469 Phil. 763 (2004) — Cited for the principle that the essence of treachery is a sudden, unexpected, and unforeseen attack without provocation, and that a forewarned victim who meets the danger negates treachery. The Court applied this to hold that Joel's awareness of the danger precluded appreciation of treachery.
• People vs. Discalsota, 430 Phil. 406 (2002) — Cited for the rule that treachery cannot be appreciated when the victim had the opportunity to flee or defend himself. Applied to negate treachery because Joel had armed himself with a bamboo pole and was aware of the danger.
• Razon vs. People, 552 Phil. 359 (2007) — Cited for the doctrines on unlawful aggression as a condition sine qua non of self-defense and on the cessation of unlawful aggression when the aggressor flees, distinguishing retaliation from self-defense.
• People vs. Mediado, G.R. No. 169871, February 2, 2011 — Cited for the principle that an accused who admits the killing and invokes self-defense bears the burden of proving justification with clear and convincing evidence.
• People vs. Corpuz, G.R. No. 191068, July 17, 2013 — Cited for the two elements of treachery: that the means of execution gives the victim no opportunity to defend himself, and that the methods were deliberately or consciously adopted.
• Colinares vs. People, G.R. No. 182748, December 13, 2011 — Cited for the principle that if the victim's wounds are not fatal, the crime is only attempted, and for the modification of moral damages in attempted homicide.

• Article 11(1), Revised Penal Code — Defines self-defense as a justifying circumstance requiring: (a) unlawful aggression; (b) reasonable necessity of the means employed to prevent or repel it; and (c) lack of sufficient provocation on the part of the person defending himself. The Court found all requisites absent, particularly unlawful aggression.
• Article 14, Revised Penal Code — Defines treachery as a qualifying circumstance when the offender employs means, methods, or forms in the execution of the crime that tend directly and specially to insure its execution without risk to himself arising from the defense the offended party might make. The Court held treachery was not proven in Joel's killing.
• Article 248, Revised Penal Code — Defines Murder and enumerates its qualifying circumstances, including treachery. The Court held that since treachery was not proven, the conviction could not stand as Murder.
• Article 249, Revised Penal Code — Defines Homicide. Casas was convicted under this article for Joel's killing after treachery was not appreciated, with the indeterminate penalty of six years and one day of prision mayor to seventeen years of reclusion temporal.
