Affirmitive defenses are more that just a simple denial, they bring up issues that can result in an acquital or lesser liabilty (Hall, 2015.) Things that fall under affirmative defenses include the question of a defendant's mental state to commit a crime, whether justification or excuse exsited to commit the crime, and an alibi (Hall, 2015.) "A defense that is more that a simple denial of charges. It raises a new matter they may result in an acquittal or a reduction of liability. It is a defense that must be affirmatively raised, often before trail or it is lost" (Hall, 2015.)
