Q

3) What are the M’Naughten rules?

A

Usually, the accused are conscious that they weren’t supposed to the act they did was wrong, and the jury assumed that every man is presumed to be sane and responsible for their crime.

However, to use the Insanity defence, it must be clearly proved that the defendant:

i) had a disease of the mind
ii) defect of reason
iii) did not know the nature and quality of his act or knew it was wrong.

Q

4) Explain ‘disease of the mind’ and its relevant CASES. (hint: brain blood supply, epilepsy)

A

This must be a mental or physical disease which IS NOT caused by external facts like drugs. It can be a permanent or temporary state.

R v Kemp - Condition which caused a problem with brain blood supply. He had temporary unconsciousness and during a black out committed GBH.However, the temporary unconsiousness counted as a ‘disease of the mind’.

R v Sullivan - Kicked a neighbour during an an epliptic fit. Courts held that this counted as eplipsy fits have an effect on the mind and fits are classed as insanity. It’s not automatism as there’s no external factor.

Q

5) Explain ‘defect of reason’ and its relevant CASES. (hint, absentmindness, internal factor/sleepwalking)

A

The defendant’s powers of reasoning must be impaired.

R v Clarke - CoA held ‘defect of reason’ is valid alongside the M’Naughten rules. Their mind must be discussed in order to equate more than absent-mindness or confusion.

R v Burgess - D hit friend with blunt objects during sleep. Medical abuse stated that there was no external causes and the sleep walking as triggered by an internal sleeping disorder. Court held internal factors = insanity.

Q

6) Explain ‘not knowing the nature & quality of the act’ -‘ and it’s relevant CASE.
(hint: ‘Suppose they’ll hang me for this?’)

A

The defendant has to show at least one of hese conditions at the time of the act, they can satisfy this M’Naugten rule.

  • doesn’t know what they’re doing or understand what they’re doing due to their mental conditions.
  • doesn’t apperciate the conswuences of theit act.
  • doesn’t apperciate the circumstances they’re acting in.

R v Windle - Killed suicidal wife and gave himself up. He said ‘I’ll suppose they’ll hang me for this?” - indicating he knew it was legally wrong so he COULDN’T use the insanity plea.

Q

12) Voluntary manslaughter can negate the mens rea for a SPECIFIC INTENT OFFENCE ONLY? What is an example of these and what is the relevant CASE?
(hint: zerkaa)

A

Specific intent offences are murder, gbh s.18 etc.

DPP v Beard - D claimed he was too intoxciated to fulfil the mens rea for murder. Court held that if someone is so intoxicated that they were incapable of forming the intent required, then they have to be acquitted.

Q

14) What happens in murder cases when intoxication is used? Relevant CASE?
(hint: LIP MAN EMOJIS HERE)

A

Voluntary intoxication can be a defence to murder as it’s specific intent but then it’s usually reduced down to manslaughter, which is basic intent and cannot be a defence to manslaughter.

R v Lipman - Whilst on LSD, believed his girlfriend was snakes attacking him, so defended himself by shoving cloth down her throat. Convicted of manslaughter because of reasons above, so still guilty.

Q

16) What case shows that involuntary intoxication is a weak defence? (hint: capatial of Jamaica)

A

R v Kingston - D was drugged by someone who wanted to blackmail him. He was then lured to a minor and sexually abused him whilst being photographed. He was convicted because it’s not clear if the drugs were a factor in him performing this rape.

17
Q

17) What is automatism?

A

A complete defence where the defendant proves the body acted without any control by the mind. This is due to an external factor.

18
Q

18) What does Bratty say about automatism?

A

D was convicted because Lord Denning stated that ‘automatism is an act done by the muscle without any control by the mind. An example would be a spasm, reflex action, an person who’s done an act after being concussed or suffering from sleep walking. Therefore, D taking off the tights was none of these, but the strangulation probably was.

19
Q

19) What CASE talks about partial or reduced control of one’s actions being sufficient to constitute automatism?

A

Attorney-General’s Reference - Automatism occurs when there’s a total loss of control. Therefore impaired or reduced control IS NOT sufficient . D had some control of the lorry as he was able to steer, so was partially aware of his surroundings and therefore COULD NOT claim automatism - he was convicted for murder.

20
Q

20) What is self-induced automatism? State the relevant CASE (hint: black guy from The Dumping Ground)

A

This is where the defendant knows that their conduct is likely to bring on an automatic state. Examples include people drinking alcohol when they’re on a medication that doesn’t allow alcohol consumption.

R v Bailey - D was a diabetic who faile who to eat enough after taking his insulin to control his diabetes. He became agressive and hit someone over the head with an iron bar. Automatism wasn’t avaliable even after appeal.
