Insanity/automatism Flashcards
Defence of insanity, stages:
- Defect of reason;
- Disease of the mind;
- Nature and quality of his act/that the act was wrong.
- Defect of reason, info and case:
Defect of reason arises when the defendant is incapable of exercising the ordinary powers of reasoning.
R v Clarke
Facts: defendant charged with theft after putting groceries in her bag. Claimed acted absent-mindedly whilst suffering from depression.
Principle: held that a ‘defect of reason’ required inability to exercise reason rather than failure to do so at the time. Inability, not failure.
- Disease of the mind, info and case:
Definition has moved far away from the medical conception of insanity.
R v Sullivan
Facts: the defendant caused GBH during an epileptic fit.
Principle: the HoL held that the nature of the disease, physical or psychological, was irrelevant provided it affected the ‘mental faculties of reason, memory and understanding’ at the time of the offence.
(3) Nature and quality of the act, info:
Requires a lack of awareness of the physical nature of the act. There must be a difference between the defendant’s action and what he thinks he is doing.
(3) Knowledge that the act is wrong, info and case:
If the defendant is aware of the nature and quality of the act, he may still raise insanity in his defence if he does not know that his actions are wrong (legally).
R v Windle
Facts: defendant medically insane, gave suicidal wife an overdose. Upon arrest, made reference to likelihood that would hang for his actions.
Principle: ‘wrong’ means ‘contrary to the law’. Defendant’s comment showed awareness that his conduct was contrary to the law so insanity was not established.
Automatism, stages:
- Complete loss of control;
- An external cause;
- Automatism must not be self-induced.
- Complete loss of control, info and case:
Based on involuntary actions, defendant must suffer complete loss of control.
Broome v Perkins
Facts: defendant sought to rely on automatism for charges arising from erratic driving whilst in hypoglycaemic shock.
Principle: automatism requires a complete loss of control. The defendant maintained some control by steering and breaking.
- External cause, info:
The distinction between automatism and insanity is based upon external and internal causes. External cause, such as a blow to the head, gives rise to automatism.
- Automatism must not be self-induced, info and case:
Automatism leads to acquittal in recognition that the defendant’s ability to control his actions render him blameless for this behaviour.
R v Bailey
Facts: failing to eat after taking insulin, despite awareness that this could lead to uncontrolled behaviour, amounted to self-induced automatism.
Intoxication, dutch courage:
AG for Northern Ireland v Gallagher
Facts: defendant decided to kill his wife, and in doing so, bought a whiskey and a knife, to give himself the courage to go through with it. Once drunk, slit wife’s throat, claimed he was so intoxicated he was incapable of forming the intention to kill at the time he killed his wife.
Principle: a person who forms an intention to kill whilst sober and drinks to give himself Dutch courage to do the killing, cannot rely on intoxication to avoid liability.
Lord Denning: “the wickedness of his mind before he got drunk is enough to condemn him.”
Intoxication, basic intent:
DPP v Majewski
Facts: the defendant attacked a police officer whilst voluntarily intoxicated. He argued that he was so intoxicated he could not form the requisite mens rea.
Principle: the effect of the intoxication on the defendant’s state of mind was only relevant to crimes of specific intent. In crimes of basic intent, the defendant’s recklessness in taking drugs that rendered his behaviour uncontrolled was in itself sufficient to substitute for mens rea.
Involuntary intoxication, cases:
R v Hardie
Facts: took Valium, usually calming but set house on fire.
Principle: Valium known for its sedative effects. Consumption of non-dangerous drugs would amount to involuntary intoxication unless the consumption itself was reckless.
R v Kingston
Facts: defendant drugged without knowledge for blackmailing, committed indecent act with drugged young male. Claimed drugs eroded his usually controlled paedophillic urges.
Principle: although the defendant’s will was weakened, still aware of his situation and knew his actions were wrong. Had mens rea for offence.
Self-defence statute:
s. 76 of Criminal Justice and Immigration Act 2008.
Elements of self-defence:
Self-defence must involve ‘reasonable force’: s. 76(1)(b) of the Criminal Justice and Immigration Act 2008.
This has two elements:
- force must be necessary;
- force must be proportionate.
Necessity of force, info:
Must be judged from the defendant’s perspective, so the key question is ‘did the defendant think he needed to use force to protect himself, his property….?’
