In criminal law, actus reus, Latin for "guilty act", is one of the elements normally required to prove commission of a crime in common law jurisdictions, the other being mens rea. In the United States it is sometimes called the external element or the objective element of a crime.
In Western jurisprudence, concurrence is the apparent need to prove the simultaneous occurrence of both actus reus and mens rea, to constitute a crime; except in crimes of strict liability. In theory, if the actus reus does not hold concurrence in point of time with the mens rea then no crime has been committed.
False imprisonment or unlawful imprisonment occurs when a person intentionally restricts another person's movement within any area without legal authority, justification, or the restrained person's permission. Actual physical restraint is not necessary for false imprisonment to occur. A false imprisonment claim may be made based upon private acts, or upon wrongful governmental detention. For detention by the police, proof of false imprisonment provides a basis to obtain a writ of habeas corpus.
False arrest, unlawful arrest or wrongful arrest is a common law tort, where a plaintiff alleges they were held in custody without probable cause, or without an order issued by a court of competent jurisdiction. Although it is possible to sue law enforcement officials for false arrest, the usual defendants in such cases are private security firms.
An attempt to commit a crime occurs if a criminal has an intent to commit a crime and takes a substantial step toward completing the crime, but for reasons not intended by the criminal, the final resulting crime does not occur. Attempt to commit a particular crime is a crime, usually considered to be of the same or lesser gravity as the particular crime attempted. Attempt is a type of inchoate crime, a crime that is not fully developed. The crime of attempt has two elements, intent and some conduct toward completion of the crime.
Fagan v Metropolitan Police Commissioner is a leading case that confirms the need for concurrence of actus reus and mens rea in most offences of the criminal law of England and Wales. It also advises realisation that a battery is ongoing will render the omission to act to remove that battery being inflicted a conscious battery, being sufficient concurrence.
In English criminal law, public nuisance is a act, condition or thing that is illegal because it interferes with the rights of the general public.
Malfeasance in office is any unlawful conduct that is often grounds for a just cause removal of an elected official by statute or recall election, or even additionally a crime. Malfeasance in office contrasts with "misfeasance in office", which is the commission of a lawful act, done in an official capacity, that improperly causes harm; and "nonfeasance in office", which is the failure to perform an official duty.
Bolam v Friern Hospital Management Committee [1957] 1 WLR 582 is an English tort law case that lays down the typical rule for assessing the appropriate standard of reasonable care in negligence cases involving skilled professionals such as doctors. This rule is known as the Bolam test, and states that if a doctor reaches the standard of a responsible body of medical opinion, they are not negligent. Bolam was rejected in the 2015 Supreme Court decision of Montgomery v Lanarkshire Health Board in matters of informed consent.
Common assault is an offence in English law. It is committed by a person who causes another person to apprehend the immediate use of unlawful violence by the defendant. In England and Wales, the penalty and mode of trial for this offence is provided by section 39 of the Criminal Justice Act 1988.
In law, an omission is a failure to act, which generally attracts different legal consequences from positive conduct. In the criminal law, an omission will constitute an actus reus and give rise to liability only when the law imposes a duty to act and the defendant is in breach of that duty. In tort law, similarly, liability will be imposed for an omission only exceptionally, when it can be established that the defendant was under a duty to act or duty of care.
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.
Murder is an offence under the common law legal system of England and Wales. It is considered the most serious form of homicide, in which one person kills another with the intention to unlawfully cause either death or serious injury. The element of intentionality was originally termed malice aforethought, although it required neither malice nor premeditation. Baker, chapter 14 states that many killings done with a high degree of subjective recklessness were treated as murder from the 12th century right through until the 1974 decision in DPP v Hyam.
R v Miller is an English criminal law case demonstrating how actus reus can be interpreted to be not only an act, but a failure to act.
English criminal law concerns offences, their prevention and the consequences, in England and Wales. Criminal conduct is considered to be a wrong against the whole of a community, rather than just the private individuals affected. The state, in addition to certain international organisations, has responsibility for crime prevention, for bringing the culprits to justice, and for dealing with convicted offenders. The police, the criminal courts and prisons are all publicly funded services, though the main focus of criminal law concerns the role of the courts, how they apply criminal statutes and common law, and why some forms of behaviour are considered criminal. The fundamentals of a crime are a guilty act and a guilty mental state. The traditional view is that moral culpability requires that a defendant should have recognised or intended that they were acting wrongly, although in modern regulation a large number of offences relating to road traffic, environmental damage, financial services and corporations, create strict liability that can be proven simply by the guilty act.
The omissions of individuals are generally not criminalised in English criminal law, save in many instances of a taking on of a duty of care, having contractual responsibility or clearly negligent creation of a hazard. Many comparator jurisdictions put a general statutory duty on strangers to rescue – this is not so in English law. Defenders and reasoners of the position regard it as wrong for the criminal law to punish people in many circumstances for committing no physical act, which it is argued would be an infringement on human autonomy. Academics arguing for reform argue that a social responsibility to assist others should exist, particularly where there would be no danger to the rescuer.
Aiding and abetting is a legal doctrine related to the guilt of someone who aids or abets another person in the commission of a crime. It exists in a number of different countries and generally allows a court to pronounce someone guilty for aiding and abetting in a crime even if he or she is not the principal offender. The words aiding, abetting and accessory are closely used but have differences. While aiding means providing support or assistance to someone, abetting means encouraging someone else to commit a crime. Accessory is someone who in fact assists "commission of a crime committed primarily by someone else". However, some jurisdictions have merged being an accessory before the fact with aiding and abetting.
In English criminal law, an inchoate offence is an offence relating to a criminal act which has not, or not yet, been committed. The main inchoate offences are attempting to commit; encouraging or assisting crime; and conspiring to commit. Attempts, governed by the Criminal Attempts Act 1981, are defined as situations where an individual who intends to commit an offence does an act which is "more than merely preparatory" in the offence's commission. Traditionally this definition has caused problems, with no firm rule on what constitutes a "more than merely preparatory" act, but broad judicial statements give some guidance. Incitement, on the other hand, is an offence under the common law, and covers situations where an individual encourages another person to engage in activities which will result in a criminal act taking place, and intends for this act to occur. As a criminal activity, incitement had a particularly broad remit, covering "a suggestion, proposal, request, exhortation, gesture, argument, persuasion, inducement, goading or the arousal of cupidity". Incitement was abolished by the Serious Crime Act 2007, but continues in other offences and as the basis of the new offence of "encouraging or assisting" the commission of a crime.
English law contains homicide offences – those acts involving the death of another person. For a crime to be considered homicide, it must take place after the victim's legally recognised birth, and before their legal death. There is also the usually uncontroversial requirement that the victim be under the "King's peace". The death must be causally linked to the actions of the defendant. Since the abolition of the year and a day rule, there is no maximum time period between any act being committed and the victim's death, so long as the former caused the latter.
R v Adomako[1994] UKHL 6, was a landmark United Kingdom criminal law case where the required elements to satisfy the legal test for gross negligence manslaughter at common law were endorsed and refined. It was held that in cases of manslaughter by criminal negligence involving a breach of duty the gross negligence test relied on by the Court of Appeal was sufficient and that it was not necessary to direct a jury to consider whether the recklessness definition should be applied. The test, as set out in R v Bateman 19 Cr. App. R.8 and Andrews v DPP [1937] AC 576, confirmed that there needed to be in existence a breach of duty of care where the serious and obvious risk of death was reasonably foreseeable and that the breach or omission in question caused actual death and that the conduct of the defendant, when all the circumstances were considered, was so bad as to amount to a criminal act or omission. The requirement to show that the defendant's breach of duty was "gross" helped develop the definition of gross negligence.
