Negligence is a failure to exercise appropriate and or ethical ruled care expected to be exercised amongst specified circumstances. The area of tort law known as negligence involves harm caused by failing to act as a form of carelessness possibly with extenuating circumstances. The core concept of negligence is that people should exercise reasonable care in their actions, by taking account of the potential harm that they might foreseeably cause to other people or property.
Automatism is a rarely used criminal defence. It is one of the mental condition defences that relate to the mental state of the defendant. Automatism can be seen variously as lack of voluntariness, lack of culpability (unconsciousness) or excuse (Schopp). Automatism means that the defendant was not aware of his or her actions when making the particular movements that constituted the illegal act. For example, Esther Griggs in 1858 threw her child out of a first floor window believing that the house was on fire, while having a sleep terror. In 2002, Peter Buck, lead guitarist of the band R.E.M., was cleared of several charges, including assault, which resulted from automatism brought on by a bad interaction between alcohol and sleeping pills. In a 2009 case in Aberporth in west Wales, Brian Thomas strangled his wife in their camper van, also during a sleep terror, when he mistook his wife for an intruder. The defence of automatism is denying that the person was acting in the sense that the criminal law demands. As such it is really a denial-of-proof – the defendant is asserting that the offence is not made out. The prosecution does not have to disprove the defence as is sometimes erroneously reported; the prosecution has to prove all the elements of the offence including the voluntary act requirement. Automatism is a defence even against strict liability crimes like dangerous driving, where no intent is necessary.
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.
Causation is the "causal relationship between the defendant's conduct and end result". In other words, causation provides a means of connecting conduct with a resulting effect, typically an injury. In criminal law, it is defined as the actus reus from which the specific injury or other effect arose and is combined with mens rea to comprise the elements of guilt. Causation only applies where a result has been achieved and therefore is immaterial with regard to inchoate offenses.
In the English law of tort, professional negligence is a subset of the general rules on negligence to cover the situation in which the defendant has represented him or herself as having more than average skills and abilities. The usual rules rely on establishing that a duty of care is owed by the defendant to the claimant, and that the defendant is in breach of that duty. The standard test of breach is whether the defendant has matched the abilities of a reasonable person. But, by virtue of the services they offer and supply, professional people hold themselves out as having more than average abilities. This specialised set of rules determines the standards against which to measure the legal quality of the services actually delivered by those who claim to be among the best in their fields of expertise.
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.
In English tort law, an individual may owe a duty of care to another, to ensure that they do not suffer any unreasonable harm or loss. If such a duty is found to be breached, a legal liability is imposed upon the tortfeasor to compensate the victim for any losses they incur. The idea of individuals owing strangers a duty of care – where beforehand such duties were only found from contractual arrangements – developed at common law, throughout the 20th century. The doctrine was significantly developed in the case of Donoghue v Stevenson, where a woman succeeded in establishing a manufacturer of ginger beer owed her a duty of care, where it had been negligently produced. Following this, the duty concept has expanded into a coherent judicial test, which must be satisfied in order to claim in negligence.
Causation in English law concerns the legal tests of remoteness, causation and foreseeability in the tort of negligence. It is also relevant for English criminal law and English contract law.
In English law, diminished responsibility is one of the partial defences that reduce the offence from murder to manslaughter if successful. This allows the judge sentencing discretion, e.g. to impose a hospital order under section 37 of the Mental Health Act 1983 to ensure treatment rather than punishment in appropriate cases. Thus, when the actus reus of death is accompanied by an objective or constructive version of mens rea, the subjective evidence that the defendant did intend to kill or cause grievous bodily harm because of a mental incapacity will partially excuse his conduct. Under s.2(2) of the Homicide Act 1957 the burden of proof is on the defendant to the balance of probabilities. The M'Naghten Rules lack a volitional limb of "irresistible impulse"; diminished responsibility is the volitional mental condition defence in English criminal law.
In the English law of homicide, manslaughter is a less serious offence than murder, the differential being between levels of fault based on the mens rea or by reason of a partial defence. In England and Wales, a common practice is to prefer a charge of murder, with the judge or defence able to introduce manslaughter as an option. The jury then decides whether the defendant is guilty or not guilty of either murder or manslaughter. On conviction for manslaughter, sentencing is at the judge's discretion, whereas a sentence of life imprisonment is mandatory on conviction for murder. Manslaughter may be either voluntary or involuntary, depending on whether the accused has the required mens rea for murder.
In the English law of negligence, the acts of the claimant may give the defendant a defence to liability, whether in whole or part, if those acts unreasonably add to the loss.
R v Quick [1973] QB 910 is an English criminal case, as to sane automatism and the sub-category of self-inducement of such a state. The court ruled that it may not be used as a defence if the defendant's loss of self-control was on the part of neglience in consuming or not consuming something which someone ought to but the jury must be properly directed so as to make all relevant findings of fact. The ruling stresses that automatism is usually easily distinct from insanity, in the few cases where the lines are blurred it is a complex problem for prosecutors and mental health professionals.
Albrighton v RPA Hospital, is a tort law case concerning the application of the Bolam test for professional negligence.
Landeros v. Flood was a 1976 court case in the state of California involving child abuse and alleged medical malpractice.
R v Jordan (1956) 40 Cr App R 152 was an English criminal law case that has been distinguished by two later key cases of equal precedent rank for its ruling that some situations of medical negligence following a wounding are those of breaking the chain of causation, capable of absolving a person who has inflicted bodily harm of guilt for an offence of the severity resulting from a consequent decline in bodily condition, in particular, homicide. The facts were ones whereby a wound was should to be almost certain, with no treatment, to heal itself. The medical attempt to facilitate recovery from the wound resulted in a non-prosecutable death as it was shown to have been negligent and principally an antibiotic error though far from unknown and well-intentioned. The appropriate charge(s) would be ones relating to wounding or disorder of the defendant, rather than homicide which could not have been said to have been caused by the defendant in any meaningful way.
In Osborn v. Irwin Memorial Blood Bank, 5 Cal.App.4th 234 (1992), the Court of Appeals of California considered certain questions pertaining to whether a blood bank could be held liable for negligence or negligent misrepresentation after a patient contracted HIV/AIDS as a result of a blood transfusion.
The eggshell rule is a well-established legal doctrine in common law, used in some tort law systems, with a similar doctrine applicable to criminal law. The rule states that, in a tort case, the unexpected frailty of the injured person is not a valid defense to the seriousness of any injury caused to them.
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 "Queen'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.
Venning v Chin (1974) 10 SASR 299 is a Supreme Court of South Australia Full Court judgement, by which it was decided that in trespass cases, the onus lies on the defendant to disprove fault. However, for injuries caused in highway accidents, the onus is on the plaintiff to prove fault on the part of the defendant.
Walsh v Jones Lang Lasalle Ltd [2017] IESC 38, is a decision of the Irish Supreme Court in which the court held that a purchaser bears the risk of reliance on erroneous information unless the vendor has clearly assumed responsibility for its accuracy. In reaching this decision, the court clarified the law in Ireland "in relation to the effect of statements disclaiming liability in actions claiming negligent misstatement."
