Study Notes
Automatism
- Defined by Lord Denning as: "connoting the state of a person who, through capable of action is not conscious of what he is doing…it means unconscious involuntary action, and it is a defence because the mind does not go with what is being done"
- Denial of voluntariness: ordinary link between mind and behavior is absent or distorted
- Can occur where prohibited conduct occurs due to involuntary movements of the body
- Leads to an acquittal, as the defendant is not engaging with the conduct
Automatism: Denial
- A complete loss of voluntary control of conduct is required
- Any degree of voluntariness is still considered voluntariness
- Erratic or irrational voluntariness is still considered voluntariness
- Presumption of voluntariness in criminal law
Application: Automatism
- Applied narrowly in driving cases
- Broome v Perkins: diabetic failed to take sufficient food after insulin injection, drove erratically, and collided with another car
- AGs Reference (No 2 of 1992): lorry driver had a condition of driving without awareness, killed two people
- R v Coley: defendant believed he was a video game character, killed a neighbor, and blamed heavy cannabis use
Automatism Prior Fault
- Like intoxication, prior fault can substitute for the missing fault element(s) at T2
- 3 elements required:
- D must have done the AR elements in the state of automatism
- D's automatism must have stemmed from earlier blameworthy conduct (prior fault)
- D must have suffered from a disease of the mind
- Disease of the mind: an internally caused lack of MR/voluntariness
- Legal concept, not medical
- Physical state of the brain or permanence of the condition is irrelevant
Insanity
-
Not a medical category, but a legal concept
-
Relies on internal cause of lack of responsibility
-
3 elements:
- D does AR and forms corresponding MR, but claims they were insane at the time
- A denial of offence: D does AR but lacks MR due to insanity
- Special verdict: not guilty by reason of insanity
-
M'Naughten rules:
- Every person is presumed sane
- D must rebut the presumption
- R v Sullivan: epileptic seizure, kicked friend in the head, and caused GBH### Insanity Defence
-
Must meet three criteria:
- Disease of the mind
- Defect of reason
- Lack of responsibility
Disease of the Mind
- An internally caused lack of MR/voluntariness
- Not a medical concept, but a legal one
- Physical state of the brain or permanence of the condition is irrelevant
- R v Kemp: Physical condition causing a congestion of blood in the brain can be considered a disease of the mind
- R v Quick: External causes, such as hypoglycaemia, can be distinguished from internal causes
Defect of Reason
- Must be a defect of reason, not just absent-mindedness
- R v Clarke: Mild depression and absent-mindedness did not prevent Defendant from being able to reason
- Defendant must be unable to think or reason properly
Lack of Responsibility
- Must fall within one of two options:
- Did not know the nature or quality of their act
- Did not know what they were doing was wrong
- Relates to physical aspects of Defendant's conduct
- R v Windle: Defendant knew what he was doing was legally wrong, despite being weak-willed and obsessed with the idea
- R v Keal: Defendant knew what he was doing was legally wrong, despite being mentally ill and under delusions
