Case Summary (G.R. No. 4912)

Incident Overview

On March 20, 1907, Emilia Guy-Sayco attacked Lorenza Estrada with a penknife, inflicting five wounds that resulted in Lorenza’s death. Prior to the incident, Emilia's husband had been involved in an extramarital affair with Lorenza, which was known to Emilia. After a prolonged absence of her husband, Emilia decided to confront him and discovered him dining with Lorenza.

Nature of the Attack

Emilia entered the house where her husband and Lorenza were present and, in a state of jealousy, immediately attacked Lorenza without any dialogue. This impulsive act was characterized by its brutality, as one of the inflicted wounds penetrated the deceased's heart, confirming the fatal nature of the assault.

Legal Proceedings

Following the attack, the provincial fiscal filed a complaint on May 31, 1907. The court subsequently rendered a judgment on June 29, 1908, convicting Emilia of homicide as defined in Article 404 of the Penal Code, and sentencing her to twelve years and one day of reclusion temporal, along with civil liability to indemnify Lorenza's heirs in the amount of P1,000.

Defense Argument

Emilia pleaded not guilty, claiming self-defense. Her argument was predicated on the assertion that she was provoked by Lorenza, who allegedly confronted her while brandishing a knife. However, this claim was undermined by testimonies from witnesses who were present during the attack.

Evidence and Testimonies

Witnesses Roberto Villaran, Susana de Mesa, and others provided accounts that contradicted Emilia's narrative, affirming that she initiated the conflict. The court emphasized the lack of credible evidence supporting the notion of self-defense, noting that a mere threatening demeanor from Lorenza did not constitute unlawful aggression sufficient to justify Emilia's violent reaction.

Judicial Findings on Aggression

The court reaffirmed that for a self-defense claim to succeed, there must be actual and unlawful aggression present, which was absent in this case. The mere presence of a knife in Lorenza’s hand, coupled with her question to Emilia, did not satisfy the legal requirements for indicating an explicit threat.

Mitigating Circumstances Consideration

While the court acknowledged Emilia's emotional state—acting under the influence of passion and jealous rage—as a mitigating factor, it did not view this as sufficient to absolve her of criminal liability. The court referenced mitigating circumstance No. 7 from Article 9 of the Penal Code, emphasizing the necessity for careful consideration of the defendant's mental state while ensuring accountability for the crime committed.
