In jurisprudence, an excuse or justification is a defense to criminal charges that is distinct from an exculpation. Exculpation is a related concept which reduces or extinguishes a person's culpability and therefore a person's liability to pay compensation to the victim of a tort in the civil law.The "excuse" provides a mitigating factor for a group of persons sharing a common characteristic. Justification, as in justifiable homicide, vindicates or shows the justice. Thus, society approves of the purpose or motives underpinning some actions or the consequences flowing from them (see Robinson), and distinguishes those where the behavior cannot be approved but some excuse may be found in the characteristics of the defendant, e.g. that the accused was a serving police officer or suffering from a mental illness. Thus, a justification describes the quality of the act, whereas an excuse relates to the status or capacity (or lack of it) in the accused. These factors can affect the resulting judgment which may be an acquittal, or in the case of a conviction may mitigate sentencing.
