Aberratio Ictus, Error In Personae, and Praeter Intentionem

Governing Principle

Aberratio ictus, error in personae, and praeter intentionem are applications of the rule that a person who commits a felony by dolo is liable even when the wrongful act done is different from that intended. The controlling premise is responsibility for the direct, natural, and logical consequences of a felonious act.

The initial act must itself be felonious. If the act was lawful and performed with due care, the resulting injury is not attributed through these doctrines; if the act was intentional and unlawful, liability follows even though the victim, blow, or degree of harm turned out differently from the offender's design.

These doctrines do not erase criminal liability. They identify the proper felony, determine whether a penalty-adjusting rule applies, and explain when several felonies produced by one act are punished as a complex crime.

Aberratio Ictus

Aberratio ictus means mistake in the blow. The offender directs a felonious act against an intended victim, but by reason of poor aim, deflection, movement, miscalculation, or a similar error in execution, the blow falls on another person.

The essence is that the offender knew whom he wanted to hit, but the execution of the blow miscarried. The error is in the direction or effect of the physical act, not in the identity of the person selected as the target.

Requisites

• The offender performed an intentional felonious act against an intended victim.
• The act was capable of producing the intended injury or offense.
• Because of mistake in the blow or execution, another person was injured or killed, or both the intended victim and another person were harmed.
• The injury to the unintended victim was a direct, natural, and logical consequence of the felonious act.

The offender is liable for the injury or death of the unintended victim because criminal intent attaches to the felonious act. The law does not allow the offender to say that the person actually hit was not the person he meant to hit when the harm flowed from the unlawful attack he voluntarily made.

If the intended victim is also injured, liability extends to the felony committed against the intended victim and the felony committed against the unintended victim. The legal treatment then depends on whether the harms came from one act or from several distinct acts.

Effect on Crimes Produced

When a single act constitutes two or more grave or less grave felonies, Article 48 on complex crimes may apply. A single discharge of a firearm that is directed at one person but kills another, while also amounting to an attempted or frustrated killing of the intended target, can therefore produce a complex crime if the statutory requirements are present.

Article 48 does not apply merely because the acts occurred in one encounter. If the offender fired several separate shots or delivered several distinct blows, each act must be examined separately, and separate felonies may arise when the criminal acts are divisible.

If the intended victim was not hit but the shot or blow was directed at him with intent to kill, the act may still constitute attempted homicide or attempted murder against the intended victim. The death or injury of the unintended victim supplies the consummated or attempted felony against that victim, subject to the rules on complex crimes when both felonies result from one act.

Qualifying circumstances are not presumed from the mere fact that the wrong person was hit. Treachery, evident premeditation, abuse of superior strength, or any circumstance that changes the nature of the offense must be established by the manner of execution and the facts attending the actual felony.

Error In Personae

Error in personae means mistake in identity. The offender aims at and strikes the person he has selected, but that person is not the person he intended to offend because he misidentified the victim.

The execution does not miscarry in error in personae. The offender's blow lands exactly on the person he chose to attack; the mistake lies in believing that the person before him was someone else.

Requisites

• The offender intended to commit a felony against a particular person.
• The offender performed the felonious act against a person whom he believed to be the intended victim.
• The person actually offended was different from the intended victim because of mistake in identity.
• The resulting injury or death was caused by the felonious act.

The general effect is liability for the felony committed against the actual victim. A deliberate attack does not become innocent because the attacker chose the wrong person under a mistaken belief.

If the felony intended and the felony committed are the same in nature and carry the same penalty, the mistake in identity usually has no effect on criminal liability. A person who intends to kill one private individual but kills another private individual by mistaken identity is liable for the killing actually committed.

Article 49 becomes important when the felony committed is different from the felony intended and the penalties are not the same. It is a penalty rule for principals in cases where the offender's mistaken identity produces a felony different from the one he meant to commit.

Article 49 Effects

• If the penalty for the felony committed is higher than the penalty for the felony intended, the penalty for the intended felony is imposed in its maximum period.
• If the penalty for the felony committed is lower than the penalty for the felony intended, the penalty for the felony committed is imposed in its maximum period.
• If the acts also constitute an attempted or frustrated felony for which the law prescribes a higher penalty, the higher penalty for the attempted or frustrated felony, in its maximum period, controls.

The practical reason for Article 49 is proportionality. The offender is punished for the felony that resulted from his unlawful act, but the law considers the difference between the intended felony and the felony actually committed when the difference changes the penalty.

Personal circumstances of the actual victim matter when they are elements of the crime or legally relevant circumstances. Relationship, public status, age, sex, or other special conditions do not transfer from the intended victim to the actual victim; they must exist in relation to the person actually offended and must be considered under the rules governing the specific offense.

When the law requires knowledge of a special relationship or status, mistake may affect whether that circumstance qualifies the offense. When the law punishes the objective result regardless of the offender's mistaken identity, the mistake does not defeat liability.

Praeter Intentionem

Praeter intentionem means that the injurious result went beyond the offender's intention. The offender intended to cause a lesser wrong, but a graver harm resulted from the felonious act.

The doctrine is reflected in the ordinary mitigating circumstance that the offender had no intention to commit so grave a wrong as that committed. It presupposes an intentional felony; it does not apply to a purely accidental act performed without fault or to a felony punished only by negligence.

Requisites for Mitigation

• The offender committed an intentional felonious act.
• A graver injury or offense resulted from that act.
• The offender did not intend to produce the graver result.
• The absence of intent to cause the graver wrong is shown by objective facts, such as the weapon used, the part of the body struck, the number and force of blows, the offender's conduct before and after the act, and the disparity between the intended harm and the actual result.

Praeter intentionem mitigates but does not exculpate. The offender remains liable for the resulting felony when the result is the direct, natural, and logical consequence of the unlawful act, but the penalty is affected because the wrong actually done was more serious than the wrong intended.

The mitigating circumstance is not appreciated when the means employed naturally and plainly tended to cause the graver result. Repeated stabbing, shooting at a vital part, strangulation, burning, or a sustained armed assault ordinarily contradicts a claim that the offender did not intend so grave a wrong.

The circumstance may be appreciated when the facts show a real disparity between the act intended and the injury produced. A single fist blow, push, slap, or minor assault that unexpectedly causes death or serious injury may support praeter intentionem if the resulting harm remains causally connected to the unlawful act and intent to cause the graver harm is not shown.

Intent to kill is essential in attempted or frustrated homicide or murder because the victim survives and the court must determine the criminal purpose behind the overt acts. When death actually results, the offender may be liable for homicide even without proof that death was intended, provided the death was caused by the felonious act; praeter intentionem then becomes relevant to mitigation.

Praeter intentionem differs from accident. Accident negates criminal liability when the act is lawful, performed with due care, and produces injury by mere misfortune; praeter intentionem assumes an unlawful intentional act and only reduces the penalty because the result exceeded the intent.

Comparative Treatment

Causation

All three doctrines require a causal link between the felonious act and the resulting wrong. The offender is not an insurer of every later event; liability attaches when the result is the direct, natural, and logical consequence of the act and no efficient intervening cause breaks the chain.

The felonious act need not be the sole cause of the injury. It is enough that it remains an efficient cause without which the result would not have occurred in the manner it did.

The victim's frailty, ordinary medical complications, or imperfect treatment does not automatically sever causation when the original injury remains operative. A wholly independent event that alone produces the final injury may break the chain, but the intervening cause must be sufficient to displace the felonious act as the legal cause of the result.

Foreseeability in this context does not require that the offender predicted the exact victim, exact path of the blow, or exact medical consequence. It requires that the harmful result be a natural consequence of the kind of unlawful force or danger voluntarily created.

Relationship to Stages of Execution

In aberratio ictus, the intended felony may remain attempted or frustrated while the felony against the unintended victim may be consummated. The stage depends on the acts performed, the result produced, and whether the offender had performed all acts of execution that would have produced the intended felony as a consequence.

In error in personae, the stage is determined by what happened to the actual victim, subject to Article 49 when the intended felony and committed felony differ. The intended victim may have no separate felony committed against him if no overt act was directed at him as an actual object of execution.

In praeter intentionem, the stage usually follows the graver result actually produced. If death results from an intentional unlawful injury, the offense is treated according to the resulting death, while the absence of intent to cause so grave a wrong is considered only in mitigation when supported by the facts.

Practical Distinctions

• In aberratio ictus, the offender's target is correct in his mind, but the blow goes astray.
• In error in personae, the blow lands where intended, but the offender selected the wrong person because of mistaken identity.
• In praeter intentionem, the offender strikes the intended person, but the harm becomes more serious than intended.
• Aberratio ictus commonly raises Article 48 because one physical act may produce felonies against more than one person.
• Error in personae commonly raises Article 49 because the identity mistake may make the felony committed different from the felony intended.
• Praeter intentionem commonly raises Article 13(3) because the issue is mitigation due to the absence of intent to cause the graver wrong.
• None of the three doctrines benefits an offender whose chosen means clearly shows intent to cause the grave result actually produced.
• None of the three doctrines applies unless the resulting harm is legally attributable to the offender's felonious act.
