G.R. No. L-5272 March 19, 1910
Mistake of Fact
Facts: The defendant, Ah Chong, was employed as a cook at "Officers' quarters and at the same place Pascual Gualberto, deceased, was employed as a house boy or muchacho.
One night, the defendant, who had received for the night, was suddenly awakened by some trying to force open the door of the room. He sat up in bed and called out twice, "Who is there?". Due to the heavy growth of vines along the front of the porch, the room was very dark, and the defendant, fearing that the intruder was a robber or a thief, leaped to his feet and called out. "If you enter the room, I will kill you." At that moment he was struck just above the knee by the edge of the chair which had been placed against the door. In the darkness and confusion the defendant thought that the blow had been inflicted by the person who had forced the door open, whom he supposed to be a burglar, though in the light of after events, it is probable that the chair was merely thrown back into the room by the sudden opening of the door against which it rested. Seizing a common kitchen knife which he kept under his pillow, the defendant struck out wildly at the intruder who, it afterwards turned out, was his roommate, Pascual. Seeing that Pascual was wounded, he called to his employers who slept in the next house, No. 28, and ran back to his room to secure bandages to bind up Pascual's wounds.
There had been several robberies in Fort McKinley not long prior to the date of the incident just described, one of which took place in a house in which the defendant was employed as cook; and as defendant alleges, it was because of these repeated robberies he kept a knife under his pillow for his personal protection.
The defendant was charged with the crime of assassination, tried, and found guilty by the trial court of simple homicide
Issue: Whether Ah Chong should be acquitted by reason of a mistake as to the facts
Held: Since evil intent is in general an inseparable element in every crime, any such mistake of fact relieves the actor from criminal liability provided always there is no fault or negligence on his part
A careful examination of the facts as disclosed in the case at bar convinces us that the defendant Chinaman struck the fatal blow alleged in the information in the firm belief that the intruder who forced open the door of his sleeping room was a thief, from whose assault he was in imminent peril, both of his life and of his property and of the property committed to his charge; that in view of all the circumstances, as they must have presented themselves to the defendant at the time, he acted in good faith, without malice, or criminal intent, in the belief that he was doing no more than exercising his legitimate right of self-defense; that had the facts been as he believed them to be he would have been wholly exempt from criminal liability on account of his act; and that he can not be said to have been guilty of negligence or recklessness or even carelessness in falling into his mistake as to the facts, or in the means adopted by him to defend himself from the imminent danger which he believe threatened his person and his property and the property under his charge.
The judgment of conviction and the sentence imposed by the trial court should be reversed, and the defendant acquitted of the crime with which he is charged and his bail bond exonerated, with the costs of both instance de oficio.
