What is Imperfect Self-Defense Under California Law?

April 29, 2023

Imperfect self-defense is a legal defense in California that can be used in cases of murder or manslaughter. It is based on the idea that the defendant believed they were acting in self-defense, but that belief was not reasonable.

Under California law, self-defense is defined as the use of reasonable force to protect oneself from an imminent threat of harm. In order for self-defense to be considered reasonable, the defendant must have had an honest and reasonable belief that they were in imminent danger of death or great bodily injury, and that the use of force was necessary to protect themselves from that danger.

However, if the defendant’s belief that they were in imminent danger was not reasonable, their actions may be considered imperfect self-defense. In this case, the defendant’s actions were not legally justifiable, but their belief that they needed to act in self-defense can be taken into consideration as a mitigating factor when determining the appropriate punishment.

For example, suppose a person is confronted by another individual in a dark alley, and the person reasonably believes that the other individual is about to attack them. In this case, the person would be justified in using force to defend themselves. However, if the person was confronted by an individual who was simply asking for directions, and the person unreasonably believes that they were about to be attacked, their actions would be considered imperfect self-defense.

When a defendant raises the defense of imperfect self-defense, the prosecution must prove beyond a reasonable doubt that the defendant’s belief was not reasonable. The jury will then consider this defense as a mitigating factor when determining the appropriate punishment.

It’s important to note that imperfect self-defense only applies to cases of murder or manslaughter, and not to cases of voluntary or involuntary manslaughter. In cases of voluntary manslaughter, the defendant had the intent to kill, but that intent was the result of a sudden quarrel or heat of passion. In cases of involuntary manslaughter, the defendant did not intend to kill but was acting in a reckless or negligent manner.

In a case of voluntary manslaughter, the prosecution does not have to prove intent to kill and imperfect self-defense is not applicable, in the case of involuntary manslaughter, imperfect self-defense does not apply as there was no intent to kill and the defendant was acting recklessly or negligently.
