SELF DEFENSE
When self-defense is invoked, the burden of evidence shifts to the accused to show that the killing was legally justified. Having owned the killing of the victim, the accused should be able to prove to the satisfaction of the Court the elements of self-defense in order to avail of this extenuating circumstance. He must discharge this burden by clear and convincing evidence. When successful, an otherwise felonious deed would be excused, mainly predicated on the lack of criminal intent of the accused. Self-defense requires that there be (1) an unlawful aggression by the person injured or killed by the offender, (2) reasonable necessity of the means employed to prevent or repel that unlawful aggression, and (3) lack of sufficient provocation on the part of the person defending himself. All these conditions must concur.
Unlawful aggression, a primordial element of self-defense, would presuppose an actual, sudden and unexpected attack or imminent danger on the life and limb of a person – not a mere threatening or intimidating attitude but most importantly, at the time the defensive action was taken against the aggressor. To invoke self-defense successfully, there must have been an unlawful and unprovoked attack that endangered the life of the accused, who was then forced to inflict severe wounds upon the assailant by employing reasonable means to resist the attack.
