Chapter 11: General Defences: Automatism Flashcards
What are general defences?
- General defences are defences which can be raised to most crimes including for the offence of murder
- Unlike characteristics of specific defences. General defences operate either to negate/negative an element of a crime in which the case will result in no crime,or to operate as a defence to a fully constituted crime
- It is prima facie, in that the defence being allowed, are in the hands of the judge discretion (whether to apply it or not)
- Although if the general defence negates one of the elements of a crime, discretion is not needed
What is the point/reason of raising defence of insanity?
It completely negates mens rea, as the defendant lacked the mental responsibility to understand their own actions
Why does insanity have the ability to negative mens rea?
It is an object under criminal law to punish those that are responsible for their actions
- But it this objective cannot be fulfilled by punishing a defendant who clearly lacks the mental responsibility for their actions
- No purpose is served in deterring and blaming someone who has not acted with full mental volition
- These defences are viewed as negating mens rea. That the defendant claims that he lacked the mental capacity, because of his disorder, to understand either the nature of his actions or their consequences
When is the time to plead the defence of insanity?
Before trial (at the arraignment)
- The accused is asserting incapacity to understanding the proceedings or the required plea or instruct his counsel
During the trial
- Accused assets that he did not have the mental responsibility at the time of the act
After trial (before sentencing)
- Accused is asserting that he should not be imprisoned because of his insanity
Criminal Procedure (Insanity and Unfitness to Plead) Act 1991
- Came into effect on 1 January 1992
- Improved the position of the defendant whose fitness to plead is questioned at outset of the proceedings, and to increase the range of disposition options open to the court following the special verdict ‘Not guilty by reason of insanity’.
- However this act doesn’t change the definition to insanity in M’Naghten Rules [1843]
What is the fitness to plead?
Before, a defendant can be found to be unfit to plead before the issue of liability is investigated. This can result in a defendant being detained in a secure hospital simply on the basis of his or her unfitness to plead.
The Criminal Procedure Act 1991 is designed to improve the situation of such defendants by requiring a court which has found a defendant unfit to plead, to continue with trial of the facts to the extent of ascertaining whether or not the defendant committed the actus reus of the offence alleged.
It developed
- disposal
- burden of proof
What is disposal
- Under 1991 Act, if such a defendant is found not to have committed the actus reus, he must be acquitted
- the act increased the range of disposal options available to the courts provided the offence is not one that attracts a mandatory penalty
Supervision and treatment order
Guardianship order
Order the defendant’s admission to hospital for a limited or unlimited period
Disposal options
- Supervision and treatment order
- Guardianship order
- Order the defendant’s admission to hospital for a limited or unlimited period
- Discharge the defendant completely
created more methods of treating the decions
Who bears the burden of proof? What is the burden of proof?
BOP lies on the defendant to satisfy on the balance of probabilities
What type of defence is the defence of insanity?
A general defence - Can apply as a defence for all crimes of negligence and crimes of strict liability (Hennessy [1898] 2 All ER 9 CA)
What is the substance of law that regards insanity
- Definition laid down in M’Naghten’s Rules in 1843. Reaffirmed in the case of R v Sullivan (1983)
- Presumption - innocence, sanity, Possess a sufficient degree of reason to be responsible for their crimes until the contrary is proven
-
Requirements - Medical case must be adduced (R v Dickie) and
the 3 elements under M’Naghten Rules must be satisfied
What are the 3 elements of insanity in M’Naghten
Important
‘It must be clearly proved that, at the time of 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 what he was doing wrong.’
- Defect of reason
- From disease of the mind
- Defendant did not know the nature and quality of the act; OR he knew he did it, but he did not know he was doing what was wrong about it
What is the disease of the mind?
A defect from some internal degenerative factor which has an organic cause
- Devlin J - ‘… The distinction between the two categories is irrelevant for the purpose of the law, which is not concerned with the origin of the disease or the cause of it but simply with the mental condition which has brought about the act…’
- A disease of the mind is not a disease of the brain. It is also immaterial whether the disease was permanent, temporary, curable, or incurable
What is the case that supports the disease of the mind
R v Sullivan
- Facts - S attacked an elderly man while suffering from an epileptic seizure
- Held - Lord Diplock stated that obiter that a disease of the mind (internal) might not cover ‘temporary impairments (of the mental faculties) resulting from an external physical factor such as a blow to the head…or the (therapeutic) administration of an anaesthetic
What is the case that reaffirms R v Sullivan
proves Sullivan right
R v Quick v Paddison
- Hypoglycaemia, malfunction of the mind was an external factor, which wasn’t the disease of the mind, but automatism
- Therefore, the general rule is that in situations where the accused’s mind was affected by certain internal factors, the defence of insanity is available to him but not if the malfunctioning of his mind is caused by external factor
Hyperglycaemia is insanity, but hypogylcaemia is automatism
What is defect of reason?
- It must negate the mental ability (mens rea), inability to reason or understand or memory being impared
