Criminal Defences + Attempts Flashcards
What is the legal definition of insanity?
a defendant is “not guilty by reason of insanity” if they have had a disease of the mind impair their ability to understand the nature actions (M’Naughten)
What are the steps for insanity?
1 - the defendant must have been labouring under a “defect of reason” meaning they could not reason at the time of their offence
2 - the defect of reason must have come from a disease of the mind, defined as something ‘internal’
3 - the defect of reason must cause the defendant to not know the nature and quality of the act, or if they did, they did not know that their actions were wrong
4 - the special verdict (given if the defence succeeds)
What are the relevant cases for step 1 of insanity?
Clarke - temporary absentmindedness does not count
Burgess - being asleep does count
What are the relevant cases for step 2 of insanity?
Hennessey - failure to take medication counts if the defect of reasoning occurs from an internal disease or illness such as diabetes or schizophrenia
Burgess - sleepwalking = disease of the mind
Kemp - narrowing of arteries = disease of the mind
Sullivan - epilepsy = disease of the mind
Lipman - intoxication is not a disease of the mind
Lord Denning - “any mental disorder that seems to manifest violence and is prone to recur” is a disease of the mind
What are the relevant cases for step 3 of insanity?
Sullivan - couldn’t know the nature of their act as the defendant was having an epileptic fit
Kemp - the defendant cannot know the nature of their act if they are unconscious
Windle - the defendant has no defence if they know their actions are illegal (“they will hang me for this”)
What are the relevant cases for step 4 of insanity?
The 3 things the judge can impose are:
- hospital order (defendant requires medical help)
- supervision order (keep an eye on the defendant)
- absolute discharge (defendants actions are unlikely to be repeated)
What is the legal definition for non-insane automatism?
When the defendants actions were caused by an inability to control themselves as a result of an external factor (Bratty)
What are the steps for non-insane automatism?
1 - the defendant acted involuntarily as they had no control over their actions (AG Ref 1992)
2 - the defendants lack of control was caused by an external factor
3 - the external factor cannot be self induced (Bailey)
What are the relevant cases for step 1 of non-insane automatism?
Lord Denning - defines an involuntary act as an act which is done by the muscles without any control by the mind such as a spasm, reflex or convulsion. Or an act done by a person who is not conscious of what they are doing
AG Ref 1994 - any person who is driving their car must have had ‘some control’
What are the relevant cases for step 2 of non-insane automatism?
Hill v Baxter - swarm of bees = external factor
R v T - anything which causes trauma or stress count as an external factor
What are the relevant cases for step 3 of non-insane automatism?
Lipman - taking LSD is a self induced factor
Hardie - taking drugs which have unpredicted side effects are not self induced factors
Majewski - becoming voluntarily intoxicated is a self induced factor
Bailey - self induced factors don’t count for crimes of basic intent, however self induced automatism can be used for crimes of specific intent
What is the legal definition of intoxication?
when the defendant does not not have the mens rea for the relevant offence due to being intoxicated
What are the steps for intoxication?
1 - is the defendant voluntarily intoxicated? If so they never have a defence for crimes of basic intent, but may have a defence for crimes of specific intent
What are the maybe cases for intoxication?
Majewski - intoxication can never be used as a defence for crimes of basic intent if voluntarily intoxicated
O’Grady - doesn’t matter if the defendant became intoxicated hours before the offence occurs
Gallagher - “Dutch courage” = intoxication
Kingston - involuntary intoxication is irrelevant if the defendant intended to commit the offence regardless of whether they were intoxicated or not
Lipman - if a drug has an unpredictable side affect then it is involuntary intoxication
Allen - you are still voluntarily intoxicated even if the alcohol is stronger than you expected
Beard - crimes of specific intent will be reduced to their basic intent counterpart if the defence is successful
What is the legal definition of self defence?
When the defendants actions were of necessary use regarding what they believe was required during the situation, thus not being liable for the crime resulting in a full acquittal
