Week 7 Criminal law- defences Flashcards
What is the current law on infancy? How has the case of T 2009 reinforced the law?
- The common law idea that children aged between 10-14 had a defence of doli incapax unless it could be proved that they knew it was seriously wrong was abolished.
- S34 of Crime and disorder act 1998 says “The rebuttable presumption of criminal law that a child aged 10 or over is incapable of committing an offence is abolished”. The defence rather than the mere presumption had been abolished despite contention.
- Following T [2009] 1AC 1310, HL concluded there was no authority for the existence of the defence separate from the presumption and that parliaments intention was clearly to abolish the concept of doli incapax as having any effect in law.
- “B, who was aged 12 at the time of the offences, had been convicted on 12 counts of causing or inciting a child under 13 to engage in sexual activity. He had pleaded guilty after the trial judge ruled that the defence of doli incapax was not available to him. B’s appeal against conviction on the ground that the judge’s ruling was wrong was unsuccessful.”
Why is a very strict approach taken declaring someone unfit for trial?
- Finding someone unfit for trial denies their right to a full criminal trial and therefore a very strict approach is required. If someone is found to be unfit to trial, a new approach is undertaken in that a trial of the facts is undergone. This determines whether the actus reus of the crime was committed by D, and he may be acquitted if this cannot be proved. If its found that he has done the acts, a range of disposal powers will be enforced, as he has not been convicted, including admission to a mental institution.
What is the M’Naghten rule?
- M’Naghten rule: “The jurors ought to be told in all cases that every man is presumed to be sane, and to possess sufficient degree of reason to be responsible for his crimes, until the contrary be proved to their satisfaction; and that to establish a defence on the ground of insanity, it must be clearly proved that, at the time of the committing of the act, the party accused was labouring under such a defect of reason, from disease of the mind, as not to know the nature and quality of the act he was doing, or, if he did know it, that he did not know he was doing what was wrong”
How can the M’Naghten rule be simplified into different components?
- Everyone presumed to be sane unless proven otherwise
- Lapse of judgment
- D must know neither the nature and quality of his act (denial of mens Rea) arising from a disease of the mind or;
- Even though he knows the nature and quality of his act, he could not know it was wrong because of a disease of the mind
What is the significance of Ds act coming from a disease of the mind and not simply a lack of MR?
- Has to be a defect of reason from a disease of the mind, otherwise its likely that his mistake came from a lack of mens rea and therefore would lead to an acquittal anyway. In the former case it relies on evidence from D whereas in the latter case it is on the prosecution to prove otherwise. However if D simply doesn’t realise its wrong, this wont amount to a defence.
- The judge is the adjudicator on whether the disease of the mind suffices for a plea of insanity, expert evidence is nothing more than a guide for the judge, and cannot be conclusive in law.
What is the difference between insanity and sane automatism?
- Distinction between insanity and sane automatism; a transitory malfunction of the mind is not a disease of the mind when it is caused by some external factor eg a concussion, alcohol or drugs. In such cases where is a total loss of capacity sane automatism may be pleaded, and imposes no burden of proof on D. Whereas insanity must be proved by D on the balance of probabilities and results in a special verdict of not guilty by reason of insanity, alongside extensive actions in relation to what the defendant should be subject to after his trial.
What does Sullivan 1984 show about what constitutes a disease of the mind?
- Sullivan 1984 AC 156: the defence to a charge of assault occasioning ABH was that D attacked V whilst recovering from a minor epileptic seizure and did not know what he was doing. The Lords rightly saw this amounted to a defence of insanity, D then changed his plea to guilty, to an offence that he blatantly wasn’t culpable for, but his conviction was upheld.
- Diseases of the mind are not necessary ones which derive from the mind but those which affect the functioning of the mind, such as a tumour, epilepsy or even diabetes.
Quick 1973 facts and significance
(diabetes and insanity)
compared to Hennesy 1989
- Quick 1973 QB 910: D who had caused ABH called medical evidence to show that he was a diabetic and that he was suffering from a hypoglycaemic attack at the time of the alleged offence and was unaware of what he was doing (defence of insanity), which D pleaded guilty. On appeal it was held that Ds mental condition at the time of the offence was caused not by Ds diabetes (internal factor) but by his use of insulin prescribed by the doctor coupled with his failure to follow that prescription by eating after injecting insulin (external factors). A plea of sane automatism should’ve been left to the jury. Shows fine line between the two pleas and the possible success of such pleas.
- In Hennesy the taking of another persons car was due to a hyperglycaemic episode as it resulted from his underlying diabetes and could properly be described as a disease of the mind.
What effect must Ds disease of the mind have on his reasoning abilities?
(Clarke 1972 depression and absentmindedness)
- The ‘disease of the mind’ has to have given rise to a ‘defect of reason’; Ds power of reasoning must be impaired and Ds mere failure to use powers of reasoning which he possesses does not bring him within the M’Naghten rules.
- In Clarke, D claimed that she had taken articles from a supermarket without paying for them because of absent-mindedness resulting from depression it was held that even if she was suffering from a disease of the mind, (which is arguable), she had not raised the defence of insanity but was simply denying that she had MR. This could help recognise those who are morally irresponsible.
What does ‘nature and quality’ refer to in the M’Naghten rules of insanity?
(not legal or moral reasoning)
- The phrase nature and quality of his acts refers to the physical nature and quality of the act and not to its moral or legal quality. It simply means D did not know what he was physically doing and therefore has narrow applications. Strange but relevant example is the man who cuts a womans throat believing himself to be cutting a loaf of bread. Obviously they have no mens rea here and therefore cant be murderers anyway, but the distinction is that if the delusion arose from a disease of the mind, he will be detained in hospital but some other cause will see him go free. Insanity can be pleaded as a defence irrespective of whether it is an offence of mens rea.
Why and how is D acquitted (or not) on a decision of not guilty by insanity when he does not know that his acts are wrong?
- This is not concerned with whether the accused is able to distinguish between right or wrong in general, but whether he was able to appreciate the wrongness of the particular act he was doing at the particular time of the alleged crime. It has always been clear that if D knows his act was contrary to the law, he knew it was wrong (R v Johnson), even if morally, he believed it to be right/ justifiable.
- Even if D did not know that it was contrary to the law, he was still liable if he knew it was wrong ‘according to the ordinary standard adopted by reasonable men’ (objective)
- Modern cases suggest the courts are concerned with Ds knowledge of legal rather than moral wrongs. If he is suffering from diseases but still knows that it is legally wrong, he can still be liable for the crime.
Johnson 2007 facts and significance (wrongs as a matter of law not morals)
- J was convicted of wounding with intent to cause grievous bodily harm. Following his arrest, he was diagnosed with paranoid schizophrenia and it was agreed that he had been suffering from this at the time of the attack. At trial, the plea of insanity was not available to J because evidence suggested that he knew what he was doing was against the law. Authority which rejects the arguments of the defence that D should be acquitted if, knowing his act to be wrong as a matter of law, he still believes it to be morally right. The CA confirmed ‘wrong’ is to mean legal wrong rather than moral wrong.
What is the difference between a plea of insanity and insane delusions which aren’t relevant to Ds actions?
- Must distinguish between when D is acquitted because he has a reasonable mistake as to the facts and then when he is delusional because of a disease of the mind. The rule seems merely to emphasise that delusions which do not prevent D from having mens rea will afford no defence.
- As Lord Hewart put it “the man who thinks he is John the Baptist does not entitle him to shoot his own mother”. Therefore, insane delusions do not negate criminal liability.
- D cannot claim that he suffered from an insane delusion which led to a mistake without pleading insanity; where he is insanely delusional but this does not arise from a disease of the mind, this does not preclude him from liability.
What is the basis of automatism?
- Automatism is a common law defence
- A claim by D that his consciousness was so impaired that he was acting in a state of physical involuntariness is a claim of automatism. Someone is an automaton where his conscious mind is dissociated from that part of the mind which controls action.
What are the two types of automatism?
- Two basic types: 1) Automatism arising from an internal cause from a disease of the mind, this is a plea of insanity (insane automatism) where D must prove that he did not know of the nature and quality of his act. 2) Any external cause leading to a total loss of control (sane automatism). D is not guilty unless D was at fault in inducing that state of automatism. Someone in a state of automatism (other than self-induced intoxication) cannot be guilty of an offence of it and the only question is whether he is to be found simply ‘not guilty’ or ‘not guilty by reason of insanity’. The outcome depends on how the automatism arose; arising by disease of the mind is the latter and anything else it the former. As seen before, any internal factor, mental or physical, causing a malfunction of the mind is a disease of the mind in law.
- Must be remembered that a plea of insanity will see the onus of proof fall on the defendant to prove on a balance of probabilities, but a plea of sane automatism arising from an external factor will see the evidential burden fall on the prosecution to prove that it is not the case.
How will the plea of sane automatism be successful or fail depending on whether D has taken prescription drugs or non prescription drugs, of the dangerous and non-dangerous type? (sane automatism related to the same rules as intoxication)
1) automatism arising from D taking a substance in compliance with his prescription= complete acquittal
2) automatism arising from D taking a substance other than in accordance with prescription= acquittal for specific intent crimes only
3) where D voluntarily takes drugs known to induce aggression or unpredictability (alcohol)= acquittal only for specific intent crimes
4) where D voluntarily takes drugs not known to cause aggression or unpredictability, he will only be acquitted of basic intent crimes if he was not subjectively reckless as to committing the AR of the basic intent crimes as a result of becoming intoxicated (Hardie)
How is necessity different to duress of circumstances?
-Duress of circumstances separated necessity and duress of circumstances because necessity doesn’t see D subject to being ‘irresistibly overborne with external pressure’. Duress is a threat of death or serious harm whereas necessity may not be so.
Quayle 2005 facts and significance?
Facts- D appealed his conviction for growing cannabis which was used to help treat their medical condition
Significance- necessity does not allow D to act at complete odds with parliaments intention to prohibit behaviour, especially here where even doctors weren’t allowed to prescribe weed.
-Necessity requires that there is an overborne hardship under which D must choose between breaking the law or being subject to this hardship, although such a hardship does not have to overborne D with imminent threat to life as it does with duress.
What must the nature of the threat be to D for necessity and how could it be criminal or non-criminal threat?
- There should be some imminent threat of serious death or harm.
- Traditional examples where the defence arises is where there is a danger to life, and the courts seem to have decline that the defence is available for anything less, such as theft of food for starving children. There have been cases where something less than a threat to life or serious injury has sufficed, but only involving a slight extension of ‘duress of circumstances’.
- Been held that D may rely on a defence of necessity where he is faced with natural disaster, accidents caused by human actors or criminal threats.
What is the general principle of Stephens and Dudley and why?
- Decided in Stephens and Dudley that duress of circumstances or necessity is not a defence to murder. Facts of the case are that Dudley killed and ate a boy whom he was shipwrecked with for 18 days in an open boat without food. It was found that the men probably would’ve died if they hadn’t done so and the boy probably would’ve died before they were rescued, and yet they were indicted for murder. Held that such a defence would rapidly reduce morality and further, the immorality of measuring and selecting a victim.
- The principle in Stephens and Dudley is distinguishable where there is no problem of selection, where both are going to die, it is immaterial whether two people die quicker as a result of one of their actions, pending immediate death anyway.
What is the best interest necessity as shown in Re A(conjoined twins) and what general principles does it show (distinguished from Dudley and Stephens)
- Re (a) Conjoined twins: The court held that in special circumstances it was lawful to kill the weaker of the two twins, B, in order to save the life of the stronger, A. This was not a simple matter of choice, as both would die if the operation to detach the twins wasn’t undertaken, but A would likely survive if they were detached whereas B would die anyway. 3 requirements for the defence of necessity were: 1) The act is needed to avoid inevitable and irreparable evil. 2)No more should be done than is reasonably necessary for the purpose to be achieved and 3) the evil inflicted must not be disproportionate to the evil avoided. In this case, unlike Stephens and Dudley, A was selected via the circumstances. HOWEVER this authority is not claiming to be an authority for necessity as a defence for murder “This case is too slender a thread on which to hang a far-reaching development of the common law”
- Didn’t require a value judgement as in Dudley and Stephens.
