United States vs. Mendoza

The complete justifying circumstance of self-defense requires proof that the means used to repel an unlawful aggression was reasonably necessary. Where the necessity for the killing is not proven, but unlawful aggression and lack of sufficient provocation from the defender are established, the incomplete self-defense under Article 86 of the Penal Code applies as a privileged mitigating circumstance.

The case arose during the American colonial period, governed by the old Spanish Penal Code. It involves the application of justifying circumstances, specifically self-defense, to a law enforcement officer who used deadly force against a civilian resisting arrest.

• Filed in the Court of First Instance (CFI).
• The CFI convicted the defendant.
• The defendant appealed to the Supreme Court.
• The SC modified the penalty.

• The deceased, Rufino Dizon, was creating a disturbance in front of a store.
• The defendant, Licerio Mendoza, a policeman, attempted to arrest Dizon and take him to the presidencia (municipal hall).
• Dizon refused to go and, according to the SC's assessment of the evidence, did not merely resist passively but actively attacked Mendoza with a "calicut" (a bladed weapon).
• Mendoza testified to the attack, and his account was corroborated by witness Alejandro Guevara, who intervened to separate them.
• During the struggle, Mendoza fired his revolver, killing Dizon.

• The defendant-appellant argued he acted in complete self-defense, as the deceased unlawfully attacked him with a weapon.

• The Solicitor-General, for the appellee (the United States), contended that the killing was not justified.

• Procedural Issues: N/A
• Substantive Issues:
  • Whether the killing of Rufino Dizon by Licerio Mendoza was justified under the complete self-defense provision of Article 8, No. 4 of the Penal Code.
  • If not, whether the elements of incomplete self-defense were present to mitigate the penalty.

• Procedural: N/A
• Substantive:
  1. On Complete Self-Defense: The SC ruled that the first requisite (unlawful aggression) and third requisite (lack of sufficient provocation from the defender) were proven. However, the second requisite—reasonable necessity of the means employed to repel the attack—was not met. The SC reasoned that after Dizon had struck twice with a calicut, Mendoza could not have reasonably believed it was necessary to kill him to repel the attack. Thus, complete self-defense was not established.
  2. On Incomplete Self-Defense: The SC held that the presence of two out of three requisites constituted incomplete self-defense, a privileged mitigating circumstance under Article 86 of the Penal Code. This warranted a reduction of the penalty. The SC revoked the lower court's sentence and imposed the penalty of six years and one day of prision mayor.

• Self-Defense (Complete Justifying Circumstance) — Under Article 8, No. 4 of the old Penal Code, it requires: (1) unlawful aggression; (2) reasonable necessity of the means employed to prevent or repel it; (3) lack of sufficient provocation on the part of the person defending himself. The SC applied this test and found the second element lacking.
• Incomplete Self-Defense (Privileged Mitigating Circumstance) — Under Article 86 of the old Penal Code, when not all the requisites necessary to justify the act are present, the penalty next lower than that prescribed by law shall be applied. The SC applied this doctrine because unlawful aggression and lack of provocation were present, even though the means used were not reasonably necessary.

• "If the resistance of Dizon had been passive, Guevarra would hardly have intervened, for fear that he himself might be arrested for interfering with an officer in the performance of his duty. His intervention can be explained only on the theory that the deceased was making attack on the defendant." — Used to establish unlawful aggression.
• "When the defendant fired his revolver and killed Dizon the latter, according to the defendant's own testimony, had already struck twice at him with a calicut. The character of this weapon is such that in our opinion the defendant could not then have reasonably believed that it was necessary to kill his assailant in order to repel the attack." — The core reasoning for denying complete self-defense.

• N/A. The decision does not cite prior case law.

• Article 8, No. 4 of the Penal Code — The provision defining the justifying circumstance of self-defense and its three requisites.
• Article 86 of the Penal Code — The provision governing the effect of incomplete justifying circumstances (privileged mitigation).

• N/A. The decision lists concurring justices (Arellano, C.J., Torres, Cooper, Mapa, and Ladd) but no separate opinions are detailed.

• N/A. No dissent is recorded.
