What do we mean by capacity?
Liability equation = AR + MR – Defences
But D must have, as a necessary precondition, sufficient CAPACITY to be held responsible for a criminal offence
All the Defences (in defences one)
Defences form under Capacity
DR (already covered) + Intoxication (though not a defence)
Infancy
*** Age of Criminal Responsibility **10 years
‘Doli Incapax’ rule
Abolished by Crime and Disorder Act 1998 s. 34
** R v JTB (2009)**
10 years - Children and Young Persons Act 1963 s.16
Doli Incapax rule
Between the age of 7-14 you could potentially hold that the child was liable but to prove that he/she was of sufficient capacity
So now from the age of 10 you can be criminalised
Why could the Doli Incapax rule be abolished
R v Venables
But right of fair trial was wrong (due to trialing as adults)
Fitness to Plead
R v Pritchard - Did D even know what he was being charged with
How do we know if one is unfit to plead
M (John) [2003]
1.) Understanding the charges;
2.) Deciding whether to plead guilty or not;
5) following the course of the proceedings;
6) giving evidence in his own defence.
Unfit if fails on any one ability. Burden on D on balance of probabiliti
Process of Fitness to Plead
Unfit to plead: judge based determination – having heard medical evidence
S.4A - Did the act or made the omission charged: jury decision – trial of the facts
Disposal: admission orders to hospital (with or without restriction order); supervision order; discharge
Unfitness avoids a criminal conviction, and may avoid a positive finding altogether
Where does the process of the unfit to plead procedure come from and what is the jusitifcation?
R v Antoine Lord Hutton
Purpose to strike a fair balance between need to protect a dedendant who has done nothing wrong and the need to protect the public from a defendant
What case could be used to determine whether fitness to plead is a valid form of defence?
Lord Janner
Insanity Terms + case
M’Naghten’s Case
-** OR ** if he did know it, that he did not know he what he was doing was wrong
Case explains terms of insanity - D shoots someone thinking someone else
How can you plead for insanity and what are the consequences?
1. Hospital order 2. Supervision Order 3. Absolute Discharge
Test of insanity
1. Defect of Reason
2. Caused by disease of mind
1st element to satisfy the test of Insanity
Defect of Reason
Clarke - D goes to supermarket and puts some items into her purse
She claimed absent-mindedness was not enough
2nd term of Insanity
Disease of the mind
How does Kemp define a disease of mind
Insanity
“Any internal condition affecting the brain regardless if it is temporary”
Condition of brain is irrelevant or mental health issues
How to distinguish between automatism or insanity
Note that both automatism and insanity can involve D being totally unaware of what they are doing
**Kemp [1957]: ** Internal (insanity) or external (automatism)
Sullivan (elipepsy) -> plead guilty rather than being insane
Internal meaning inside the body
3rd element for test of insanity
1.) Not knowing Nature/Quality of Act. Eg: cutting someone’s throat, thinking you are slicing a loaf of bread
2.) Not Knowing Act is Wrong (second limb)
Comes from Mcnaghten
Resulting in D either
1.) Not knowing the nature and quality of their act
2.) Not knowing that what they were doing was wrong
Does insanity apply where D knows the act is illegal, but at the time believes it to be morally right?
Immorality is irrelevant
What does the case of Sullivan say about Insanity?
“Mcnaghten criteria”
Incorporates conditions such as
But NOT
“severe mentall illness, or expert evidence diagnosing the suspect as insane, unless the Mc’Naghten criteria are met”
Does the defect of reason have to be caused by a disease of the mind?
Insanity
How often is Insanity used?
R v Quick
Does not provide automatic defence to mental illness
Only 20 defendants per year used insanity
Case law examples of disease of the mind
Insanity
Examples:
Epilepsy (Sullivan [1984])
Sleepwalking (Burgess [1991])
Diabetes causing hypoglycaemia:
→ Insanity if caused internally
(Hennessy [1989]) → Automatism if
caused by external insulin (Quick [1973])
“Not Knowing the Nature and Quality”
Insanity
Nature and quality means:
Understanding what you are physically doing.
Example: thinking you are squeezing a lemon but you are strangling a person.
