In an affirmative defense, the defendant may concede that they committed the alleged acts, but they prove other facts which, under the law, either justify or excuse their otherwise wrongful actions, or otherwise overcomes the plaintiff's claim. In criminal law, an affirmative defense is sometimes called a justification or excuse defense.[2] Consequently, affirmative defenses limit or excuse a defendant's criminal culpability or civil liability.[3] A clear illustration of an affirmative defense is self defense.[1] In its simplest form, a criminal defendant may be exonerated if they can demonstrate that they had an honest and reasonable belief that another's use of force was unlawful and that the defendant's conduct was necessary to protect themself.[4]
