An assault is the illegal act of causing physical harm or unwanted physical contact to another person, or, in some legal definitions, the threat or attempt to do so. It is both a crime and a tort and, therefore, may result in criminal prosecution, civil liability, or both. Additionally, assault is a criminal act in which a person intentionally causes fear of physical harm or offensive contact to another person. Assault can be committed with or without a weapon and can range from physical violence to threats of violence. Assault is frequently referred to as an attempt to commit battery, which is the deliberate use of physical force against another person. The deliberate inflicting of fear, apprehension, or terror is another definition of assault that can be found in several legal systems. Depending on the severity of the offense, assault may result in a fine, imprisonment, or even death.
Deadly force, also known as lethal force, is the use of force that is likely to cause serious bodily injury or death to another person. In most jurisdictions, the use of deadly force is justified only under conditions of extreme necessity as a last resort, when all lesser means have failed or cannot reasonably be employed.
Self-defense is a countermeasure that involves defending the health and well-being of oneself from harm. The use of the right of self-defense as a legal justification for the use of force in times of danger is available in many jurisdictions.
The concept of justifiable homicide in criminal law is a defense to culpable homicide. Generally, there is a burden to produce exculpatory evidence in the legal defense of justification.
Assault occasioning grievous bodily harm is a term used in English criminal law to describe the severest forms of battery. It refers to two offences that are created by sections 18 and 20 of the Offences against the Person Act 1861. The distinction between these two sections is the requirement of specific intent for section 18; the offence under section 18 is variously referred to as "wounding with intent" or "causing grievous bodily harm with intent", whereas the offence under section 20 is variously referred to as "unlawful wounding", "malicious wounding" or "inflicting grievous bodily harm".
A castle doctrine, also known as a castle law or a defense of habitation law, is a legal doctrine that designates a person's abode or any legally occupied place as a place in which that person has protections and immunities permitting one, in certain circumstances, to use force to defend oneself against an intruder, free from legal prosecution for the consequences of the force used. The term is most commonly used in the United States, though many other countries invoke comparable principles in their laws.
In law, the duty to retreat, or requirement of safe retreat, is a legal requirement in some jurisdictions that a threatened person cannot harm another in self-defense when it is possible instead to retreat to a place of safety. This requirement contrasts with the right in some other jurisdictions to stand one's ground, meaning being allowed to defend one's self instead of retreating.
A stand-your-ground law, sometimes called a "line in the sand" or "no duty to retreat" law, provides that people may use deadly force when they reasonably believe it to be necessary to defend against certain violent crimes. Under such a law, people have no duty to retreat before using deadly force in self-defense, so long as they are in a place where they are lawfully present. The exact details vary by jurisdiction.
Assault occasioning actual bodily harm is a statutory offence of aggravated assault in England and Wales, Northern Ireland, the Australian Capital Territory, New South Wales, Hong Kong and the Solomon Islands. It has been abolished in the Republic of Ireland and in South Australia, but replaced with a similar offence.
In criminal law, intent is a subjective state of mind that must accompany the acts of certain crimes to constitute a violation. A more formal, generally synonymous legal term is scienter: intent or knowledge of wrongdoing.
Self-defence is a defence permitting reasonable force to be used to defend one's self or another. This defence arises from both common law and the Criminal Law Act 1967. Self-defence is a justification defence rather than an excuse.
In the United States, self-defense is an affirmative defense that is used to justify the use of force by one person against another person under specific circumstances.
Resisting arrest, or simply resisting, is an illegal act of a suspected criminal either fleeing, threatening, assaulting, or providing a fake ID to a police officer during arrest. In most cases, the person responsible for resisting arrest is criminally charged or taken to court.
The Crimes Act1900 (NSW) is an Act of the Parliament of New South Wales that defines an extensive list of offences and sets out punishments for the majority of criminal offences in New South Wales (NSW), Australia. The Act, alongside the Crimes Act 1914 (Cth) and the Criminal Code Act 1995 (Cth), form the almost complete basis of criminal law for the State. It is the primary criminal law statute of NSW, and which formed the basis for the Australian Capital Territory's Crimes Act1900 (ACT).
In the state of Maryland, the right of self-defense is mostly governed by case law, but there is also a statute.
The Penal Law of the State of New York combines justification and necessity into a single article, Article 35. "Defense of Justification" comprises sections 35.05 through 35.30 of the Penal Law. The general provision relating to necessity, section 35.05, provides:
§ 35.05 Justification; generally.
Unless otherwise limited by the ensuing provisions of this article defining justifiable use of physical force, conduct which would otherwise constitute an offense is justifiable and not criminal when:
South African criminal law is the body of national law relating to crime in South Africa. In the definition of Van der Walt et al., a crime is "conduct which common or statute law prohibits and expressly or impliedly subjects to punishment remissible by the state alone and which the offender cannot avoid by his own act once he has been convicted." Crime involves the infliction of harm against society. The function or object of criminal law is to provide a social mechanism with which to coerce members of society to abstain from conduct that is harmful to the interests of society.
In R v K, an important case in South African criminal law, the Appellate Division held that, in cases of private defence, the assault on the accused need not be committed culpably. It is also possible to act in private defence against someone who lacks criminal capacity, such as a mentally disordered person. Centlivres CJ compared the law in South Africa with what Holmes J said in Brown v United States:
Many respectable writers agree that if a man reasonably believes that he is in immediate danger of death or grievous bodily harm from his assailant he may stand his ground and that if he kills he has not exceeded the bounds of lawful self-defence [....] Detached reflection cannot be demanded in the presence of an up-lifted knife.
State v. Abbott, 36 N.J. 63, 174 A.2d 881 (1961), is a landmark case in the American legal doctrine of retreat. In it, the New Jersey Supreme Court unanimously adopted a duty to retreat—a legal requirement that a threatened person cannot stand one's ground and apply lethal force in self-defense, but must instead retreat to a place of safety. This retreat rule is an exception to the right of self-defense.
