The concept of justifiable homicide in criminal law is a defense to culpable homicide (criminal or negligent homicide), and requires exculpatory evidence in the legal defense of justification. In most countries, a homicide is justified when there is sufficient evidence to prove beyond a reasonable doubt that it was reasonable for the subject to believe that there was an imminent and otherwise unavoidable danger of death or grave bodily harm to the innocent. A homicide in this instance is blameless and distinct from the less stringent criteria authorizing deadly force in stand your ground rulings.
Common excusing conditionsEdit
Potentially excusing conditions common to most jurisdictions include the following.
- Capital punishment.
- Where a state is engaged in a war with a legitimate casus belli, a combatant may lawfully kill an enemy combatant so long as that combatant is not hors de combat. This principle is embedded in public international law and has been respected by most states around the world. Thus, if there is no formal declaration of war or the casus belli is not legitimate, all those who engage in the fighting and kill enemy combatants could theoretically be prosecuted. Protecting the national interest against external aggressors is considered an excuse on utilitarian grounds, i.e. the greatest public good will be derived from the defeat of the enemy.
- Most countries agree that it is lawful for a citizen to repel violence with violence to protect his or her own or another's life and limb, to prevent arson of an occupied building, or to prevent violent sexual assault or to quell a riot (see below).
- Where the person's death is inflicted by the effecting of lawful arrest or prevention of lawfully detained person's escape, quelling riot or insurrection when the use of force is "no more than absolutely necessary".
- Some countries agree that it is lawful for a citizen to resort to violence to protect valuable property, usually defined as one's home.
- The "heat of the moment" defense: death results from a situation where the defendant is deemed to have lost control. This is often considered a part of the defense of provocation against a charge of murder. Based on the idea that all individuals may suddenly and unexpectedly lose control when words are spoken or events occur, jurisdictions differ on whether this should be allowed to excuse liability or merely mitigate to a lesser offense such as manslaughter, and under which circumstances this defense can be used.
- The doctrine of necessity allows, for example, a surgeon to separate conjoined twins, killing the weaker twin to allow the stronger twin to survive.
- In the United States, the 2005 Unborn Victims of Violence Act changed the legal definition of human fetuses to "unborn children", formally defining feticide as murder (under USC §1111). However, the law retains explicit exceptions which prohibit the prosecution "of any person for conduct relating to an abortion", "of any person for any medical treatment", or "of any woman with respect to her unborn child", thereby preserving the right to an abortion stemming from Roe v. Wade.
- Several countries, such as the Netherlands, Belgium, Switzerland, Japan, and the U.S. states of Oregon and Washington, allow both active and passive euthanasia by law, if justified.
European Convention on Human RightsEdit
Article 2 Paragraph 2 of the European Convention On Human Rights provides that that death resulted from defending oneself or others, arresting a suspect or fugitive, or suppressing riots or insurrections, will not contravene the Article when the use of force involved is "no more than absolutely necessary":
- 2. Deprivation of life shall not be regarded as inflicted in contravention of this Article when it results from the use of force which is no more than absolutely necessary:
- (a) in defence of any person from unlawful violence;
- (b) in order to effect a lawful arrest or to prevent the escape of a person lawfully detained;
- (c) in action lawfully taken for the purpose of quelling a riot or insurrection.
Example of Criminal Procedure Act in South AfricaEdit
In South Africa, §49 Criminal Procedure Act used to provide:
- (2) Where the person concerned is to be arrested for an offense referred to in Schedule 1 or is to be arrested on the ground of having committed such an offense, and the person authorized under this Act to arrest or to assist in arresting him cannot arrest him or prevent him from fleeing by other means than killing him, the killing shall be deemed to be justifiable homicide.
- This has now been amended by §7 Judicial Matters Second Amendment Act 122 of 1998:
- (2) If any arrestor attempts to arrest a suspect and the suspect resists the attempt, or flees, or resists the attempt and flees, when it is clear that an attempt to arrest him or her is being made, and the suspect cannot be arrested without the use of force, the arrestor may, in order to effect the arrest, use such force as may be reasonably necessary and proportional in the circumstances to overcome resistance or to prevent the suspect from fleeing: Provided that the arrestor is justified in terms of this section in using deadly force that is intended or is likely to cause death or grievous bodily harm to a suspect, only if he or she believes on reasonable grounds-
- (a) that the force is immediately necessary for the purpose of protecting the arrestor, any person lawfully assisting the arrestor or any other person from imminent or future death or grievous bodily harm;
- (b) that there is a substantial risk that the suspect will cause imminent or future death or grievous bodily harm if the arrest is delayed; or
- (c) that the offence for which the arrest is sought is in progress and is of a forcible and serious nature and involves the use of life threatening violence or a strong likelihood that it will cause grievous bodily harm.
Examples of justifiable homicide in the United StatesEdit
A non-criminal homicide ruling, usually committed in self-defense or in defense of another, exists under United States law. A homicide may be considered justified if it is done to prevent a very serious crime, such as rape, armed robbery, manslaughter or murder. The victim must reasonably believe, under the totality of the circumstances, that the assailant intended to commit a criminal act that would likely result in the death or life-threatening injury of an innocent person. A homicide performed out of vengeance, or retribution for action in the past, or in pursuit of a "fleeing felon" (except under specific circumstances) would not be considered justifiable.
In many states, given a case of self-defense, the defendant is expected to obey a duty to retreat if it is possible to do so. In the states of Alabama, Alaska, Arizona, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Indiana, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Mississippi, Missouri, Montana, New Jersey, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, West Virginia, Washington, Wyoming and other Castle Doctrine states, there is no duty to retreat in certain situations (depending on the state, this may apply to one's home, business, or vehicle, or to any public place where a person is lawfully present). Preemptive self-defense, in which one kills another on suspicion that the victim might eventually become dangerous, is not justifiable.
In the U.S. Supreme Court ruling of District of Columbia v. Heller, the majority held that the Constitution protected the right to the possession of firearms for the purpose of self-defense "and to use that arm for traditionally lawful purposes, such as self-defense within the home".
Two other forms of justifiable homicide are unique to the prison system: the death penalty and preventing prisoners from escaping. To quote the California State Penal Code (state law) that covers justifiable homicide:
- 196. Homicide is justifiable when committed by public officers and those acting by their command in their aid and assistance, either--
- 1. In obedience to any judgment of a competent Court; or,
- 2. When necessarily committed in overcoming actual resistance to the execution of some legal process, or in the discharge of any other legal duty; or,
- 3. When necessarily committed in retaking felons who have been rescued or have escaped, or when necessarily committed in arresting persons charged with felony, and who are fleeing from justice or resisting such arrest.
Although the above text is from California law, most jurisdictions have similar laws to prevent escapees from custody.
