G.R. No. L-28480-1 September 30, 1971
THE PEOPLE OF THE PHILIPPINES, plaintiff-appellee, vs. CECILIO DE LEON Y BUENAVENTURA, defendant-appellant.

FACTS

Cecilio de Leon was convicted by the trial court of murder and frustrated murder for the death of Simeon Dizon and the wounding of Guillermo Dizon. The incident originated when de Leon, clad only in an undershirt, caused a disturbance at the beauty parlor of Flora Dizon. After being ejected by Flora’s brother, Guillermo, de Leon left but promised to return. Simeon Dizon, a friend of de Leon, later went to talk to him outside. The prosecution’s version, credited by the trial court, was that de Leon suddenly and without warning stabbed Simeon and then Guillermo. In contrast, the defense claimed self-defense, alleging that Simeon initiated a fistfight, drew a pistol, and fired shots, prompting de Leon to use a knife he carried for his pig-butchering work, and that he subsequently struck Guillermo when the latter held him.

ISSUE

The primary issue is whether the accused, Cecilio de Leon, acted in legitimate self-defense. A secondary issue involves the correct classification and penalty for the crimes committed, specifically whether the killings were qualified by treachery and evident premeditation to constitute murder.

RULING

The Supreme Court rejected the plea of self-defense. The legal logic centered on the failure to prove all its requisite elements. While Simeon was armed with a pistol, the evidence established he drew and fired it only after being stabbed and after de Leon had fled. Thus, any prior fistfight did not constitute unlawful aggression of such a grave nature as to justify the retaliatory use of a lethal knife. The aggression from Guillermo, who was unarmed, was also insufficient to warrant such a deadly response. Consequently, the defense of self-defense must fail due to the absence of unlawful aggression that was imminent, real, and of a degree reasonably necessitating the means employed by the accused.
Regarding the classification of the crimes, the Court modified the trial court’s ruling. It found that the qualifying circumstances of evident premeditation and treachery were not established. The brief interval between the initial altercation and the stabbing negated sufficient time for cool reflection required for evident premeditation. On treachery, the Court found the prosecution’s narrative of a sudden, unexpected attack unconvincing, noting the prior friendship between the accused and the deceased and the likelihood the stabbing was preceded by a fistfight, as supported by the accused’s own abrasions. Without these qualifying circumstances, the crimes are homicide and frustrated homicide. Applying the Indeterminate Sentence Law, de Leon was sentenced to an indeterminate penalty of 8 years and 1 day to 14 years, 8 months and 1 day for homicide, and 2 years, 4 months and 1 day to 8 years and 1 day for frustrated homicide, with corresponding indemnities.
