Mariano vs. People

Defense of a stranger under Article 11(3) of the Revised Penal Code justifies an act otherwise criminal where unlawful aggression, reasonable necessity of the means employed, and absence of revenge, resentment, or other evil motive are established; the reasonableness of the means must be judged in light of the accused’s state of mind during the attack, not with hindsight.

Ryan Mariano and Pamela Rivera were common-law partners; Pia Rivera was Pamela’s daughter, and Yuki Rivera was Pia’s cousin. Frederick Natividad was the alleged victim in the criminal case. The Revised Penal Code, Article 11, provides justifying circumstances for defense of one’s person or rights and for defense of the person or rights of a stranger.

Ryan Mariano y Garcia was the common-law husband of Pamela Rivera and the stepfather of Pamela’s daughter, Pia Rivera; Yuki Rivera was Pia’s cousin. Frederick Natividad y San Juan was the alleged victim in the frustrated homicide charge. On July 22, 2010, at around 9:45 p.m., according to the prosecution, Natividad saw Yuki along Vergel Street. Yuki punched Natividad’s head because Yuki thought Natividad would tell Yuki’s aunt that he was selling marijuana. Natividad went to Yuki’s house to report the punching. At Yuki’s house, Natividad met Mariano and Pamela. Later, Mariano stabbed Natividad twice, once in the buttocks and once on the right side of his body.

Antonio San Juan, who was in his canteen, heard the noise outside. Upon checking, he saw that Natividad had been stabbed. He asked barangay tanod Benneth Santos to take Natividad to the hospital. San Juan noticed Mariano holding a kitchen knife. Mariano voluntarily surrendered the kitchen knife to San Juan, who then arrested and surrendered him and the kitchen knife to the police authorities. Dr. Archie B. La Madrid operated on Natividad and issued a Medical Certificate certifying a “penetrating wound at the right lobe of the liver caused by a sharp object. There was profuse bleeding from the liver.” The wound in the abdomen punctured the liver, and Natividad would have died without the timely medical intervention. The prosecution presented evidence that Natividad incurred P428,375.51 in medical bills.

According to the defense, at around 8:30 p.m. on the same date, Mariano was in his mother’s house and then went to Pamela’s house, where he saw Natividad and Yuki arguing because Yuki refused to buy marijuana for Natividad. Natividad went berserk, slapped Yuki, and kicked Pia. Mariano went inside to tell his mother-in-law and Pamela that Natividad was hurting Yuki and Pia. Pamela confronted Natividad, who then punched Pamela on the face and shoulder. Mariano pushed Natividad to the ground. Natividad stood back up, got a piece of wood, and kept hitting Mariano. Mariano evaded Natividad’s blows because Natividad was drunk and staggering. Mariano picked up a knife and stabbed Natividad on the buttocks. Due to Natividad’s continuous hitting, Mariano stabbed Natividad again on the right side of his body. Mariano claimed that he acted in self-defense and in defense of a relative.

Pamela testified that Mariano informed her and her mother that Natividad was hurting Yuki and Pia. When she went outside to confront Natividad, he punched her face and shoulder. Upon seeing this, Mariano pushed Natividad to the ground. Pamela, Pia, and Yuki went inside the house while Mariano stayed outside. Later, they learned that Mariano had stabbed Natividad. Pia and Yuki corroborated Pamela’s testimony, and none of them witnessed the stabbing because they were already inside the house when it occurred. Pia also testified that Natividad had slapped Yuki two or three times, banged and kicked the gate, caused the steel gate to hit her forehead, threw three mono block chairs at Yuki that hit her back, kicked Yuki’s right leg thinking she was Yuki, boxed Pamela on the arm, and boxed Mariano on the chest; she saw Mariano pick up a piece of wood and try to hit Natividad, and she did not see the stabbing because she was in her room.

The trial court found a conflict between Mariano’s and Pia’s testimonies as to who picked up the piece of wood: Mariano testified that Natividad picked up a piece of wood and hit him, while Pia testified that Mariano picked up a piece of wood and tried to hit Natividad. The trial court also considered the 15-minute interval between the first and second stabbing, the fact that Natividad stayed in the place and did not retaliate, and the fatal nature of the second wound to the liver. The Court of Appeals relied on Pamela’s testimony that she and the others went inside the house after Mariano pushed Natividad, and on her description of Natividad as shouting and being pacified by Benneth.

• Unlawful Aggression: Petitioner insisted that the elements of self-defense were present and that Natividad committed unlawful aggression by attacking Pia, Yuki, and Pamela; Pia and Yuki were minors, and petitioner intervened only when Natividad attacked Pamela.
• Reasonable Means: Petitioner argued that the means employed were reasonable because reasonable necessity is not absolute necessity; a person under assault cannot be expected to have the tranquility of mind to make calculated comparisons about his reaction. He maintained that he could not be expected to act differently when Natividad had repeatedly struck him with a piece of wood and had earlier punched Pamela and hit Pia’s forehead with a steel gate, and that Natividad’s actions instilled overwhelming fear and made him frantic.
• Lack of Provocation: Petitioner argued that there was lack of sufficient provocation on his part.
• Alternative Relief: Petitioner prayed for acquittal or, in the alternative, to be held liable for less serious physical injuries only and for his sentence to be reduced accordingly.

• Unlawful Aggression: The Office of the Solicitor General argued that unlawful aggression was not present because there was no actual, sudden, and unexpected danger to petitioner or his companions.
• Reasonable Means: The Office of the Solicitor General argued that the means employed to repel Natividad were not reasonably necessary because Natividad was drunk and staggering at the time of the altercation.
• Binding Factual Findings: The Office of the Solicitor General insisted that the Court of Appeals and trial court’s factual findings are binding on the Supreme Court absent exceptional circumstances.

• Defense of a Stranger: Whether petitioner acted in defense of a stranger under Article 11(3) of the Revised Penal Code, thereby justifying the stabbing and exempting him from criminal liability for frustrated homicide.
• Unlawful Aggression: Whether Natividad committed unlawful aggression against Pamela, Pia, or petitioner.
• Reasonable Necessity: Whether petitioner employed reasonably necessary means to repel Natividad’s aggression, considering petitioner’s state of mind during the incident.
• Evil Motive: Whether petitioner was induced by revenge, resentment, or other evil motive.

• Defense of a Stranger: Yes. All elements of defense of a stranger under Article 11(3) of the Revised Penal Code were present; petitioner is exonerated of frustrated homicide.
• Unlawful Aggression: Yes. Natividad’s attack on Pamela and Pia constituted unlawful aggression; an attack showing the aggressor’s intention is enough.
• Reasonable Necessity: Yes. The means employed were reasonable when judged from petitioner’s state of mind during the attack, not with hindsight; Natividad’s attacks were incessant and he had already attacked three other persons.
• Evil Motive: No. Petitioner was not induced by revenge, resentment, or other evil motive; Natividad testified that he had no prior issue with petitioner.

• Defense of a Stranger: Article 11(3) of the Revised Penal Code requires unlawful aggression, reasonable necessity of the means employed, and absence of revenge, resentment, or other evil motive. The Court of Appeals rejected the defense on the grounds that there was no unlawful aggression and that the means employed were not reasonable. However, the Court of Appeals did not reject as false petitioner’s factual allegations or evidence; it differed only on whether those facts were sufficient to comprise unlawful aggression. Its conclusion that no unlawful aggression existed relied on Pamela’s testimony, but it ignored her testimony that Natividad punched her face and shoulder, which was corroborated by Pia. Pia’s testimony detailed Natividad’s attacks on Yuki, Pia, Pamela, and Mariano. Natividad did not deny attacking Pamela or Pia because he could not remember these acts. An attack showing the aggressor’s intention is enough to consider that unlawful aggression was committed. Thus, the attack on Pamela should have been considered unlawful aggression for purposes of defense of a stranger. All elements were present, and petitioner should be exonerated.
• Unlawful Aggression: The Court of Appeals treated Natividad’s acts as mere shouting and held that unlawful aggression must be actual or imminent, offensive and positively strong, not merely imaginary or a threatening attitude. The Court found that the lower courts overlooked the evidence that Natividad attacked Pamela and Pia. Pamela testified that Natividad punched her face and shoulder; Pia testified that Natividad slapped Yuki, kicked Pia, caused the steel gate to hit Pia’s forehead, threw mono block chairs at Yuki that hit Pia’s back, kicked Yuki’s right leg, boxed Pamela on the arm, and boxed Mariano on the chest. Natividad did not deny these acts because he could not remember them. An attack showing the aggressor’s intention is enough to constitute unlawful aggression. Therefore, unlawful aggression existed.
• Reasonable Necessity: The state of mind of the accused during an alleged act of self-defense, defense of a relative, or defense of a stranger must be considered in determining whether the means of repelling an aggressor were reasonable. In Jayme vs. Repe, the Court explained that reasonable necessity does not mean absolute necessity; one who is assaulted cannot have sufficient tranquility of mind to think, calculate, and make comparisons that can easily be made in calmness; the law requires rational necessity, not indispensable need; and the defendant may be given the benefit of any reasonable doubt as to whether he employed rational means. In United States vs. Paras, where an accused was knocked to the ground and kicked and then fired several shots at his aggressor, the Court held that reasonable necessity does not depend on the harm done but rests on the imminent danger of the injury. Here, although Natividad was drunk and unable to land his blows, his attacks were incessant. He had already attacked three other persons—two minors and petitioner’s common-law wife—and was still belligerent. While Pamela, Pia, and Yuki had gone inside the house at the time of the stabbing, it then appeared to petitioner that there was no other reasonable means to protect his family except to commit the acts alleged. It is unreasonable for courts to demand conduct that could only have been discovered with hindsight and absent the stress caused by the threats that petitioner actually faced.
• Evil Motive: Petitioner was not induced by revenge, resentment, or other evil motive. Natividad himself testified that he had no issues with petitioner before the incident. Thus, all the elements to invoke the justifying circumstance of defense of a stranger were present.

• Defense of a Stranger — Under Article 11(3) of the Revised Penal Code, a person who acts in defense of the person or rights of a stranger does not incur criminal liability if (1) unlawful aggression exists; (2) reasonable necessity of the means employed to prevent or repel it; and (3) the defender is not induced by revenge, resentment, or other evil motive. The Court applied this justifying circumstance to acquit Mariano.
• Unlawful Aggression — Unlawful aggression must be an actual or imminent threat, offensive and positively strong, not merely imaginary or a threatening attitude. An attack showing the aggressor’s intention is enough to consider that unlawful aggression was committed. The Court found Natividad’s attack on Pamela and Pia sufficient.
• Reasonable Necessity and the Accused’s State of Mind — Reasonable necessity does not mean absolute necessity; the accused’s state of mind during the attack must be considered. One who is assaulted cannot be expected to have sufficient tranquility of mind to think, calculate, and make comparisons; the law requires rational necessity, not indispensable need. The Court applied this to Mariano’s repeated stabbing under incessant attacks.
• Lack of Evil Motive in Defense of a Stranger — The defender must not be induced by revenge, resentment, or other evil motive. The Court found no such motive because Natividad testified that he had no prior issue with Mariano.

• “The state of mind of the accused during an alleged act of self-defense, defense of a relative, or defense of a stranger must be considered in determining whether his or her means of repelling an aggressor were reasonable.” — This opening statement frames the ratio: reasonableness of defensive means is assessed from the accused’s perspective during the attack.
• “An attack showing the aggressor’s intention is enough to consider that unlawful aggression was committed.” — This rule supported the finding that Natividad’s attack on Pamela and Pia constituted unlawful aggression for defense of a stranger.
• “Reasonable necessity does not mean absolute necessity. It must be assumed that one who is assaulted cannot have sufficient tranquility of mind to think, calculate and make comparisons which can easily be made in the calmness of the home. It is not the indispensable need but the rational necessity which the law requires.” — Quoted from Jayme vs. Repe, this passage defines the standard for reasonable necessity applied to Mariano’s acts.
• “It is unreasonable for courts to demand conduct that could only have been discovered with hindsight and absent the stress caused by the threats that the petitioner actually faced.” — This passage explains why the lower courts erred in requiring Mariano to have chosen a less violent response.

• Jayme vs. Repe, 372 Phil. 796 (1999) — Cited for the rule that reasonable necessity does not mean absolute necessity and that the accused’s state of mind during an assault must be considered; the Court quoted it to reject the lower courts’ hindsight assessment of Mariano’s means.
• United States vs. Paras, 9 Phil. 367 (1907) — Cited as precedent where an accused who was knocked down and kicked fired several shots at his aggressor; the Court used it to hold that reasonable necessity depends on imminent danger, not the harm done.
• United States vs. Guy-Sayco, 13 Phil. 292, 295-296 (1909) — Cited in support of the rule that an attack showing the aggressor’s intention is enough to constitute unlawful aggression.

• Article 11(1), Revised Penal Code — Provides the justifying circumstance of self-defense, requiring unlawful aggression, reasonable necessity of the means employed, and lack of sufficient provocation on the part of the person defending himself. The Court cited it as the baseline for the first two requisites of defense of a stranger.
• Article 11(3), Revised Penal Code — Provides the justifying circumstance of defense of the person or rights of a stranger, requiring the first and second requisites of self-defense and that the defender not be induced by revenge, resentment, or other evil motive. The Court applied this provision to acquit petitioner.
• Article 249, Revised Penal Code — Defines and penalizes homicide; petitioner was charged with and convicted by the lower courts of frustrated homicide under this article, but the Supreme Court acquitted him after finding a justifying circumstance.
