United States vs. Guy-Sayco

A mere threatening or intimidating attitude, without an actual attack or material aggression, does not constitute unlawful aggression sufficient to sustain a claim of exemption from criminal liability on the ground of self-defense.

Emilia Guy-Sayco was the wife of Gelasio Galupitan, who had entered into unlawful relations with Lorenza Estrada. All parties were residents of the town of Santa Cruz, the capital of the Province of La Laguna. The accused became aware of this illicit relationship, and her husband had stayed away from the conjugal home for more than two weeks under the pretext of field work.

Emilia Guy-Sayco, the accused, was the wife of Gelasio Galupitan, who had entered into unlawful relations with Lorenza Estrada, the deceased. On March 20, 1907, at about 2 p.m., the accused decided to go to the barrio of Dujat, about two and one-half hours' walk from the town, where her husband had stayed for more than two weeks under the pretext of field work. She hired a carromata and, with her infant child and a servant girl, set out. Night came before she reached the barrio, and at about 7 o'clock she alighted and dismissed the vehicle. Fearing attack, she disguised herself using her husband's clothes and a hat given to her by her companion.

Upon seeing her husband's horse tied in front of a low house, she suspected he was inside. She went to the steps and saw her husband sitting with his back toward the steps. She entered the house and encountered her husband, the deceased, and the owners of the house taking supper together. Overcome and blinded by jealousy, she rushed at Lorenza Estrada, attacked her with a penknife, and inflicted five wounds upon her. Lorenza fell to the ground covered with blood and died a few moments afterwards. The accused left the house immediately after the aggression and went to the house of Modesto Ramos, where she changed her clothes.

An examination of the body by Dr. Gertrudo Reyes on the following day revealed five wounds inflicted by a cutting and pointed weapon, one of which was on the left side of the breast and penetrated the left ventricle of the heart; this wound was of necessity mortal, the others being more or less serious.

The accused pleaded not guilty and alleged in exculpation that when Lorenza Estrada saw her and heard her remonstrate with her husband, Lorenza asked what had brought her there and manifested an intention to attack her with a knife she carried. The accused claimed she caught the deceased by the right hand, grappled with her, and in the struggle managed to get hold of a penknife on the floor, though she could not say whether she struck the deceased with it. The prosecution witnesses, Roberto Villaran, Susana de Mesa, and Maria Ramos, who witnessed the aggression, testified that the accused, as soon as she entered the house, without saying a word, attacked the deceased with a penknife. They denied that the servant was present and that a penknife was found on the floor.

• Self-Defense: The accused, through counsel, claimed that in wounding the deceased she acted in proper self-defense, alleging that the deceased threatened to attack her with a knife and that the accused merely defended herself in the ensuing struggle.

N/A — The decision does not separately recount the prosecution's arguments on appeal beyond the Solicitor-General's representation of the appellee.

• Self-Defense: Whether the accused acted in legitimate self-defense when she killed Lorenza Estrada.
• Mitigating Circumstance: Whether the mitigating circumstance of passion and jealousy should be appreciated in the commission of the crime.
• Civil Liability: Whether the accused is civilly liable for indemnity to the heirs of the deceased.

• Self-Defense: No. The claim of self-defense was rejected because no unlawful aggression was established; a mere threatening or intimidating attitude does not constitute unlawful aggression under article 8, No. 4 of the Penal Code.
• Mitigating Circumstance: Yes. The mitigating circumstance No. 7 of article 9 of the Penal Code was appreciated, as the accused acted upon the impulse of passion and under great jealous excitement at the sight of her husband taking supper with his mistress.
• Civil Liability: Yes. The accused is civilly liable, as every person criminally liable for a crime is also civilly liable under article 17 of the Penal Code, and the courts shall regulate the amount of indemnity under article 122.

• Self-Defense: The Court found that the facts proven beyond reasonable doubt showed that the accused, as soon as she entered the house, without saying a word, attacked the deceased with a penknife and inflicted wounds causing immediate death. The accused's allegation of self-defense was contradicted and destroyed by the testimony of the prosecution witnesses who were present at the aggression. Even assuming the deceased arose with a knife in a threatening manner, such attitude does not constitute unlawful aggression. For unlawful aggression to exist, there must be an attack or material aggression — an offensive act positively determining the intent of the aggressor to cause an injury. A mere threatening or intimidating attitude is not sufficient to justify the commission of an act punishable per se and to allow a claim of exemption from liability on the ground of self-defense.

• Mitigating Circumstance: The Court held that the mitigating circumstance No. 7 of article 9 of the Penal Code should be considered, without any aggravating circumstance to neutralize its effects. It was proven that the accused, at the time of the crime, acted upon the impulse of passion and under great jealous excitement at the sight of her husband taking supper in the company of his mistress, after he had been absent from the conjugal dwelling for several days.

• Civil Liability: The Court cited article 17 of the Penal Code, which provides that every person criminally liable for a crime or misdemeanor is also civilly liable. According to the established rule of the courts, it is sufficient that the civil liability proceed from, or be the consequence of, the criminal liability. Article 122 of the code provides that courts shall regulate the amount of indemnity for damages upon the same terms as prescribed for the reparation of damage in article 121, and a finding on the matter should be contained in the judgment.

• Unlawful Aggression in Self-Defense — For a claim of self-defense to prosper, unlawful aggression must first be established. Unlawful aggression requires an attack or material aggression — an offensive act positively determining the intent of the aggressor to cause an injury. A mere threatening or intimidating attitude is insufficient. The Court applied this doctrine to reject the accused's self-defense claim, holding that even if the deceased arose with a knife in a threatening manner, such attitude did not constitute unlawful aggression.

• Mitigating Circumstance of Passion and Jealousy — Under article 9, No. 7 of the Penal Code, acting upon an impulse of passion and great excitement is a mitigating circumstance. The Court applied this doctrine where the accused acted under great jealous excitement at the sight of her husband taking supper with his mistress after being absent from the conjugal dwelling for several days.

• "In order to consider that an unlawful aggression was actually committed, it is necessary that an attack or material aggression, an offensive act positively determining the intent of the aggressor to cause an injury shall have been made; a mere threatening or intimidating attitude is not sufficient to justify the commission of an act which is punishable per se, and allow a claim of exemption from liability on the ground that it was committed in self-defense." — This passage defines the canonical formulation of unlawful aggression as a requisite for self-defense and is the ratio decidendi for rejecting the accused's defense.

• "It has been proven beyond a reasonable doubt that as soon as the accused entered the house where she found her husband, without saying a word, she attacked the deceased with a penknife and inflicted wounds that caused the immediate death of the latter." — This states the Court's factual finding that contradicts the accused's self-defense claim and establishes the basis for conviction.

• "Overcome and blinded by jealousy she rushed at Lorenza Estrada, attacked her with a penknife that she carried, and inflicted five wounds upon her in consequence of which Lorenza fell to the ground covered with blood and died a few moments afterwards." — This factual recital supports the appreciation of the mitigating circumstance of passion and jealousy.

N/A — The decision does not cite specific case precedents by name.

• Article 404, Penal Code — Defines and punishes the crime of homicide. The Court applied this provision because none of the circumstances qualifying the crime as assassination under article 403 were present.
• Article 8, No. 4, Penal Code — Defines the requisites for self-defense, including unlawful aggression. The Court applied this provision to reject the accused's self-defense claim for lack of unlawful aggression.
• Article 9, No. 7, Penal Code — Provides the mitigating circumstance of acting upon an impulse of passion and great excitement. The Court appreciated this circumstance in favor of the accused.
• Article 17, Penal Code — Provides that every person criminally liable for a crime or misdemeanor is also civilly liable. The Court cited this provision to affirm the indemnity awarded to the heirs of the deceased.
• Article 121, Penal Code — Prescribes the terms for reparation of damage. Referenced in relation to the regulation of indemnity.
• Article 122, Penal Code — Provides that courts shall regulate the amount of indemnity for damages upon the same terms as prescribed in article 121. The Court cited this provision to affirm the trial court's award of indemnity.

Arellano, C.J., Mapa, Johnson, and Carson, JJ., concurred.

• Justice Willard — Dissented, holding that the aggravating circumstance of disguise should be applied, and disagreeing with the majority's treatment of the matter of unlawful aggression (agresion ilegitima).
