Imperfect self-defense


Imperfect self-defense is a common law doctrine recognized by some jurisdictions whereby a defendant may mitigate punishment or sentencing imposed for a crime involving the use of deadly force by claiming, as a partial affirmative defense, the honest but unreasonable belief that the actions were necessary to counter an attack.

If the defendant's self-defense was imperfect, the self-defense may only reduce the defendant's liability. Imperfect self-defense is self-defense that was arguably necessary but somehow unreasonable. For example, if a person had a good faith belief that deadly force was necessary to repel an attack, but that belief was unreasonable, the defendant would have a claim of imperfect self-defense. In some jurisdictions, the successful invocation of such a defense reduces a murder charge to manslaughter. Most jurisdictions do not recognize imperfect self-defense.

It may also be used to make a plea bargain to a lesser included offense.

For example, in the U.S. state of California a defendant can be convicted of manslaughter but not murder when imperfect self-defense applies.

The doctrine of imperfect self-defense recognizes a defendant’s honest but unreasonable belief that deadly force is needed. An appellate court in Kansas held that "Imperfect self defense is an intentional killing committed with an unreasonable but honest belief that circumstances justified deadly force."

Another court, in Maryland, held that:

When evidence is presented showing the defendant’s subjective belief that the use of force was necessary to prevent imminent death or serious bodily harm, the defendant is entitled to a proper instruction on imperfect self defense....The theory underlying the doctrine is that when a defendant uses deadly force with an honest but unreasonable belief that it is necessary to defend himself, the element of malice, necessary for a murder conviction, is lacking.
