Law-Defences Flashcards
What are the defences?
Insanity, automatism, intoxication, self-defence and consent
What are the rules on insanity based on?
The case of M’Naghten who suffered from extreme paranoia and killed his secretary but due to mental state he was found not guilty. He was sent to a mental hospital but not due to the verdict. Because he was not guilty and not automatically sent to a hospital, he house of lords created the M’Naghten rules on insanity to answer the publics questions
What is the main rule on insanity?
“in all cases every man is presumed to be sane and to possess a sufficient degree of reason to be responsible for his crimes”
How is the defence of insanity established?
The defendant must prove that at the time of committing the act he had a defect of reason which is the result of a disease of the mind which causes the defendant not to know the nature and quality of his act, or not to know he was doing wrong
For insanity, what is the burden and standard of proof?
The burden of proving insanity is on the defence, who must prove it on the balance of probabilities
When a defendant is found to be insane, what verdict is given?
Not guilty by reason of insanity
What did the case of DPP v H decide?
Defendant was charged with driving with excess alcohol and it was held that insanity is not a defence to offences of strict liability where no mental element is required
What is defect of reason?
It means that the defendant’s powers of reasoning must be impaired. If the defendant is capable of reasoning but has failed to use those powers then this is not a defect of reason (Clarke)
What happened in the case of Clarke?
It was decided that the defect of reason must be more than absent-mindedness or confusion
What is disease of the mind?
The defect of reason must be due to a disease of the mind, which is a legal term, not a medical one. The disease can be a mental disease or physical disease which affects the mind eg Kemp, Sullivan, Hennesy, Burgess
What happened in the case of Kemp?
Defendant was found not guilty by reason of insanity due to a hardening of the arteries which caused a problem with supply of blood to the brain causing moments of temporary loss of consciousness. Court ruled it was insanity because they are interested in illnesses that affect the mind, not the brain, which is why it counted
What happened in the case of Sullivan?
Defendant had epilepsy, known to have fits and aggression to those trying to help during these times, and in this case injured an 80 year old man
What did the House of Lords rule in the case of Sullivan?
They ruled that the source of the disease was irrelevant. It could be ‘organic, as in epilepsy, or functional’, and it did not matter whether the impairment was ‘permanent, or transient and intermittent’, provided that it existed at the time that the defendant did the act. This means that for the purpose of the M’Naghten Rules the disease can be of any part of the body provided it has an effect on the mind. This extended the legal meaning of insanity far beyond the medical meaning
What happened in the case of Hennessy?
High blood sugar levels because of diabetes were classed as insanity because the levels affected the mind. Therefore the source of the disease can also be ‘organic’, meaning a disease of the organs of the body, including diseases such as epilepsy, arteriosclerosis (Kemp), brain tumours and diabetes
What happened in the case of Burgess?
It was decided that in some instances sleep-walking was also within the legal definition of insanity. It was found that the defendant was sleep walking due to a sleep disorder (an internal cause) and so was found not guilty by reason of insanity. However if the sleep walking is due to an external cause, such as a blow to the head then it is not insanity but will allow the defendant the defence of automatism
What happens if the defect of reasoning in caused by an external factor?
This is not insanity, as shown by Quirk who was diabetic which may be insane if insulin hasn’t been taken (Sullivan), but may not be insane if they have taken insulin but haven’t eaten as this counts as an external factor. If a drug hasn’t been taken and the disease causes the problem, then it is internal (disease of the mind). But if a drug has been taken and this causes the automatic state, then it is external and not insanity
What is ‘not knowing the nature and quality of the act or not knowing that it is wrong’?
Nature and quality refers to the physical character of the act. The two ways that the defendant may not know the nature of quality of the act are because they are in a state of unconsciousness or impaired consciousness, or where they are conscious but due to their mental condition they don’t understand or know what they are doing. If either of these ways can be proven to apply at the time of the act, then this part of the M’Naghten rules is satisfied
What was the case for Kemp, Sullivan, Hennessy and Burgess relating to whether they knew the nature and quality of their act, or whether it was wrong?
The defendant may not know the nature and quality of the act because they are in an automatic state and they don’t know what they are doing, which was the case in Kemp, Sullivan, Hennessy and Burgess
What is a reason, apart from being in an automatic state, that someone may not know the nature or quality of their act?
If they suffer from delusions. If a person believes eg that the devil is standing next to them and hits out at them with a knife but in actual fact kills a person, they don’t know the nature or quality of the act. The same is true if an insane person believes they are squeezing an orange but in fact they are squeezing someone’s throat
How is it possible for someone who knows the nature and quality of their act to use the defence of insanity?
I they did not know that what they did was wrong (meaning legally wrong, not morally wrong). Even if the defendant is suffering from a mental illness but knows what they did was legally wrong, they cannot use the defence of insanity, as shown by Windle
What happened in the case of Windle?
Defendant killed his suicidal wife and gave himself up to the police then said “I suppose they will hang me for this”. He had a mental illness but his words showed that knew he had done something legally wrong and so could not use the defence of insanity
What case followed Windle more recently?
Johnson, where the defendant was schizophrenic and stabbed a neighbour in their flat. Two psychiatrists said he was paranoid schizophrenic with hallucinations but both agreed that despite this, he still knew the nature and quality of his acts, and that they were legally wrong so could not use insanity
What is a major problem with the law of inanity?
The definition of insanity was set by the M’Naghten rules in 1842. At that time medical knowledge of mental disorders was very limited. Much more is known today about mental disorders and a more modern definition should be used
What are the other problems with the law of insanity?
Other problems with the legal definition of insanity, the overlap with automatism, the position of diabetics, the decision in Windle, social stigma, and proof of insanity
What are the other problems with the legal definition of insanity?
The definition has become a legal one rather than a medical problem, creating two problems. 1) people with certain mental disorders do not come under this definition even though they can’t prevent themselves from acting and have a recognised mental disorder. 2) people with physical illnesses such as diabetes, brain tumours and even sleep walking can be considered legally insane
How is the overlap with automatism a problem with the law of insanity?
It is necessary to decide whether the defendant’s automatic state is due to mental illness or external factors. The courts have to decide that those suffering from an illness that affects their mind/puts then in an automatic state amounts to insanity. This means the defence of non-insane automatism has been removed from such people as epileptics and diabetics.Serious consequences are that those successfully using the defence of automatism are entitled to a complete acquittal however insanity requires the judge to impose some order on the defendant
How is the position of diabetics a problem with the law of insanity?
The legal definition of insanity means diabetics are sometimes classed as insane, and other times not. In Sullivan it was held he came within the M’Naghten rules and so used insanity, however in Quirk, he did not come within these rules and so couldn’t use insanity, but could use automatism where he was entitled to a full acquittal
How is the decision in Windle a problem with the law of insanity?
Following the decision in Windle, a defendant who is suffering from a serious recognised mental illness and who does not know that his act is morally wrong cannot have a defence of insanity when he knows his act is legally wrong. An Australian case refused to follow this decision. In Johnson the Court of Appeal clearly thought that the Australian case had some merit but were obliged to follow Windle
How is social stigma a problem with the law of insanity?
Even the use of the word ‘insanity’ is unfortunate. It carries a social stigma. It is bad enough to apply it to people who are suffering from mental disorders, but it is entirely inappropriate to apply it to those suffering from such diseases as epilepsy or diabetes
How is proof of insanity a problem with the law of insanity?
Defendant has to prove he is insane, placing burden of proof on him. It is possible that it is in breach of Art 6 of European Convention on Human Rights that states defendant is innocent until proven guilty. Also the point that the jury are required if the defendant is insane or not which is not an appropriate function for the jury
What proposal for reform of the law on insanity was made in 1953?
The Royal Commission on Capital Punishment suggested that the M’Naghten rules should be extended for when a defendant is incapable of preventing himself from committing the offence, however instead of this the Government introduced the defence of diminished responsibility for murder and gives judges discretion on sentencing for other offences
What proposal for reform of the law on insanity was made in 1975?
The Butler Committee suggested that the verdict of not guilty by reason of insanity should be replaced with not guilty on evidence of mental disorder. In 1989 the Law Commission’s Draft Criminal Code proposed that the verdict should be not guilty on evidence of severe mental disorder or severe mental handicap, but none of these proposals were made law
What change did the Government make in 1991?
The way in which judges can deal with a defendant found guilty by reason of insanity have improved. A judge can now make: a hospital order with or without restriction; a supervision order; or an absolute discharge. These allow for a mentally ill defendant who is a danger o the community to be sent to a secure hospital, while a defendant with diabetes can be given an absolute discharge
What are recent proposals for the law on insanity?
In 2012, the Law Commission published a ‘Scoping Paper’ on insanity and automatism. The intention of the paper is to discover how these defences are working and what problems lawyers and judges find in them. The paper outlines the current law and poses a series of questions. It also offers possible alternatives, but it doesn’t make any definite proposals. The Law Commission will look at the responses and publish further papers on the issues
What case defines automatism?
Bratty v Attorney-General for Northern Ireland, which defines automatism as “an act done by the muscles without any control by the mind, such as a spasm, a reflex action or a convulsion; or an act done by a person who is not conscious of what he is doing such as an act done whilst suffering from concussion or whilst sleep walking”
What types of automatism are covered in the definition of automatism?
Insane automatism and non-insane automatism
What is insane automatism?
Whee the cause of the automatism is a disease of the mind within the M’Naghten Rules. In such a case the defence is insanity and the verdict is not guilty by reason of insanity
What is non-insane automatism?
Where the cause is an external one. Where such a defence succeeds, it is a complete defence and the defendant is not guilty
Why is non-insane automatism a defence?
Because the actus reus done by the defendant is not voluntary, and the defendant does not have the required mens rea for the offence
What is the cause of automatism for non-insane automatism?
It must be external eg a blow to the head, an attack by a swarm of bees, sneezing, hypnotism and the effect of a drug
What happened in the case of R v T?
It was accepted that exceptional stress can be an external factor which may cause automatism (defendant suffered PTSD after sexual assault)
What happened in A-G’s reference no2 of 1992?
The court of appeal held there must be ‘total destruction of voluntary control’. Reduced or partial control of one’s actions is not sufficient for non-insane automatism (case about driving without awareness)
What is self induced automatism?
Where the defendant knows that his conduct is likely to bring on an automatic state, eg a diabetic failing to eat after taking insulin
Where does the law on self induced automatism come from?
The case of Bailey where the defendant was a diabetic that did not eat enough after taking insulin to control the diabetes. He then became aggressive and hit someone over the head with an iron bar
What was decided by the Court of Appeal in the case of Bailey?
If the offence charged is one of specific intent, then self-induced automatism can be a defence, because the defendant lacks the required mens rea
What happens if the offence charged is one of basic intent?
1) the prosecution has to prove the necessary element of recklessness for the offence. 2) where the self-induced automatic state is caused through drink or illegal drugs or other intoxicating substances the defendant cannot use this defence (due to DPP v Majewski as voluntary intoxication is reckless). 3) where defendant doesn’t know his actions are likely to lead to a self-induced automatic state in which he may commit an offence, he has not been reckless and can use the offence
What happened in the case of Hardie?
Due to depression, the defendant took valium tablets that were prescribed for his ex girlfriend. He then set fire to a wardrobe in the flat and said he didn’t know what he was doing due to the valium. Trial judge told the jury to ignore the tablets and so he was convicted of arson but the court of appeal quashed the conviction as he took the drug to calm down (an effect of the drug) so hadn’t been reckless and the defence of automatism should have been used
What is the main problem with the law on automatism
In each case it has to be decided whether the situation is one of insane automatism or non-insane automatism. This is very important as the effect of these two types of automatism as a defence is so different. Situations which would seem to the non-lawyer to be ones of non insane automatism, such as a diabetic being in a high blood sugar state, or someone sleep walking may at law be considered to be insane automatism
What was a proposal for reform of the law on automatism?
In the Draft Criminal Code a new definition was suggested: “A person is not guilty of an offence if- (a) he acts in a state of automatism, that in his act (i) is a reflex, spasm or convulsion; or (ii) occurs while he is in a condition (whether of sleep, unconsciousness, impaired consciousness or otherwise) depriving him of effective control of his act; and (b) the act or condition is the result neither of anything done or omitted with the fault required for the offence nor of voluntary intoxication
Why would the reform proposed by the Draft Criminal Code be good?
It would include those who act during an epileptic convulsion eg Sullivan could then use the defence instead of insanity. Also sleep walking could come under this so eg in Burgess who could use this defence instead of insanity
What is a negative point of the reform proposed by the Draft Criminal Code?
The present system allows a judge to order medical treatment for those who are found not guilty by reason of insanity. Should there be some way of making sure that those who commit dangerous offences whilst in an automatic stat, and who would benefit from treatment, do in fact receive treatment?
What are recent proposals for the law of automatism?
In July 2012 the Law Commission published a ‘Scoping Paper’ on the defences of insanity and automatism. They point out that the two defences are so closely related that if there is to be reform of insanity, then automatism must be reformed at the same time. The Scoping Paper is a preliminary stage of considering what the problems of the defences are and what possible reforms might be made. The Law Commission will be issuing further papers on the matter
What does the defence of intoxication cover?
Intoxication by alcohol, drugs or other substances, such as glue sniffing
What does the defence of intoxication allow?
It does not provide a defence as such, but is relevant as to whether or not the defendant has the required mens rea for the offence. If he does not have the required mens rea because of the intoxicated state, then he may not be guilty
What does whether the defendant is found guilty or not, if they have been in an intoxicated state when committing the act, depend on?
1) whether the intoxication was voluntary or involuntary; and 2) whether the offence charged is one of specific or basic intent
What are specific intent offences?
Generally those which require specific intention for their mens rea- murder and s18 OAPA
What are basic intent offences?
Generally those for which recklessness is sufficient for the mens rea- manslaughter, s20 and s47 OAPA and assault and battery
