Chapter 3 - Voluntary Manslaughter Flashcards
What are the two special defences to murder?
(1) diminished responsibility
(2) loss of control
In which Act was diminished responsibility set and and in which Act was it amended?
Diminished responsibility was set out in the Homicide Act 1957 and was amended by s 52 of the Coroners and Justice Act 2009
What does a partial defence mean?
The defendant is not able to be acquitted completely as instead they just reduce the offence of murder to voluntary manslaughter
Why is it known as VOLUNTARY manslaughter?
Because the defendant had the necessary mens rea for murder
Does the judge have discretion when sentencing someone with voluntary manslaughter?
Yes, the judge does have discretion because they don’t have to impose a mandatory life sentence and can impose a more appropriate sentence
What is the definition of voluntary manslaughter?
The verdict where the defendant has a partial defence to murder when the unlawful killing was carried out when the defendant was suffering from diminished responsibility or loss of control
Before diminished responsibility was amended what was the main problem?
If a person with mental problems kills someone then their only defence was insanity and the test for insanity is very narrow and many D’s who suffer from a mental illness do not always come within it
Why was the defence of diminished responsibility developed?
Because those with mental illnesses did not always come within the narrow test of insanity and therefore left without a defence and this is why diminished responsibility was created
Under s 52 of the CJA 2009 what were the 3 elements of an abnormality of mentally functioning?
The effect of this section is that a person who kills or is a party to the killing of another is not to be convicted of murder if he was suffering from an abnormality of mental functioning which:
(a) arose from a recognised medical condition
(b) substantially impaired D’s ability to-
(i) understand the nature of his conduct
(ii) form a rational judgement
(iii) exercise self-control
(c) provides an explanation for D’s acts and omissions in doing or being a party to the killing
In diminished responsibility who is the burden of proof placed on?
The defendant, but the defendant need only prove it on the balance of probabilities
What is the definition of diminished responsibility?
A partial defence to a charge of murder which reduces the offence to one of voluntary manslaughter under s 2 Homicide Act 1957 as amended by s 52 Coroners and Justice Act 2009
When did the law require the defendant to be suffering from an ‘abnormality of mind’?
Before the definition of diminished responsibility was amended by s 52 of the Coroners and Justice Act 2009
In the case of R v Byrne what was the ‘abnormality of mind’ described as?
‘a state of mind so different from that of ordinary human being that the reasonable man would term it abnormal’
Was the case of R Byrne decided on the old definition of diminished responsibility?
Yes
What is the test for abnormality of mental functioning?
D’s mental functioning was so different from that of ordinary human beings that the reasonable man would term it abnormal
What must the abnormality of mental functioning arise from?
A recognised medical condition
Does ‘recognised medical condition’ include both psychological and physical conditions?
Yes
What are some examples of psychological recognised medical conditions which affect mental functioning?
(1) depressive illness
(2) paranoia
(3) Battered Woman’s Syndrome
What are some examples of physical recognised medical conditions that’s affects mental functioning?
(1) epilepsy
(2) sleep disorders
(3) diabetes
Must there be medical evidence presented at trial proving the D’s recognised mental condition?
Yes
What affect must the abnormality of mental functioning have of the D’s mental responsibility?
The abnormality of mental functioning must substantially impair the D’s mental responsibility for his acts or omissions in doing or being party to the killing
What was ‘substantial’ held to mean in the case of R v Lloyd?
Substantial does not mean total, nor does it mean trivial or minimal, it is something in between and is for the jury to decide if the D’s mental responsibility is impaired substantially
When can a judge decide not to put forward the question of whether the D’s mental functioning was substantially impaired?
The judge can withdraw this point from the jury if there is no evidence on which a reasonable jury could conclude that the D’s mental responsibility was substantially impaired
Was the matter of substantial impairment decided in the cases of R v Byrne and R v Lloyd before the law was amended?
Yes
What was held in the case of R v Golds about substantial impairment?
This case occurred after the law was amended and the Supreme Court pointed out that there was no indication in the 2009 Act that Parliament wished ‘substantial impairment’ to have a different meaning and therefore the meaning hasn’t changed
What are the 3 abilities that must be substantially impaired set out by the Homicide Act?
1 out of 3 of these abilities must be impaired:
(1) to understand the nature of his conduct
(2) to form a rational judgment
(3) of exercise self-control
What 2 situations does ‘ability to understand the nature of his conduct’ cover?
(1) Situations such as where D is in an automatic state and does not know what they are doing such as where the D is suffering from delusions
(2) situations where the D is suffering with severe learning difficulties whose mental age is so low that they do not understand the nature of what they are doing
What does the ‘ability to form a rational judgement’ mean?
Even if the D know the nature of their conduct they may not be able to form a rational judgement about their acts or omissions
What are 3 conditions in which a D may not be able to form a rational judgement?
(1) paranoia
(2) schizophrenia
(3) Battered Women’s Syndrome
What was a case where the D was unable to ‘exercise self-control’?
R v Byrne
Why was Byrne unable to ‘exercise self-control’?
He was a sexual psychopath and medical evidence was that his condition meant he was unable to control his perverted desires and therefore the defence of diminished responsibility was available to him
Must the D prove that the abnormality of mental functioning provides an explanation for their acts and omissions in doing or being a party to the killing?
Yes
What Act stated that there must now be some causal connection between D’s abnormality of mental functioning and the killing?
This was introduced by the Coroners and Justice Act 2009
Must the abnormality of mental functioning be the only factor which caused D to do or be involved in the killing?
No
Must the abnormality of mental functioning be a ‘significant factor’ which caused D to do or be involved in the killing?
Yes
What are the 3 possibilities to consider when the D was intoxicated at the time of the killing? (DR)
(1) that the defendant was intoxicated at the time of the killing and tries to use the defence of diminished responsibility
(2) that the defendant was intoxicated and has a pre-existing abnormality of mental functioning
(3) that the intoxication is due to an addiction
Can intoxication on its own be used as the basis of a defence of diminished responsibility?
No
Can the abnormality of mental functioning be due to intoxication?
No, the abnormality of mental functioning must be due to a recognised medical condition
Which case confirmed that an abnormality of mental functioning cannot be due to intoxication?
R v Dowds (2012)
Which cases illustrates a situation where the D was intoxicated and has a pre-existing abnormality of mental functioning?
R v Dietschmann (2003)
What is the recognised medical condition which is linked to alcohol?
Alcohol Dependency Syndrome (ADS)
What is Alcohol Dependency Syndrome?
A condition which means that a person cannot control their drinking
Is alcohol dependency syndrome sufficient for diminished responsibility?
Yes
What is the leading case on where intoxication is due to an addiction?
R v Wood (2008)
What is classed as involuntary drinking?
Where the consumption of alcohol is due to an addiction
What is classed as voluntary drinking?
Where the consumption of alcohol is not due to an addiction
What happens when there is both voluntary and involuntary drinking?
The defence of diminished responsibility can still be pleaded but the jury can only consider the effects of the involuntary drinking and they have to decide whether this substantially impaired his mental functioning
What is the three stage test for juries in cases where there is voluntary and involuntary drinking?
(1) was D suffering from an ‘abnormality of mental functioning’? - the mere fact that D has ADS would not automatically amount to an abnormality, the nature and extent of the ADS has to be considered
(2) if so, was D’s abnormality caused by the ADS?
(3) if so, was D’s mental responsibility substantially impaired? - to decide this all the evidence including the medical evidence should be considered and other relevant issues to be considered may include:
(a) the extent and seriousness of D’s dependency
(b) the extent to which D’s ability to control his drinking was reduced
(c) whether D was capable of abstinence from alcohol and if so how long
(d) whether D was choosing to get drunk or drink more than usual
(e) D’s pattern of drinking preceding the killing
(f) D’s ability to make decision about ordinary day-to-day matters
Which case set out this three stage test?
R v Stewart (2009)
What Act reformed the original law of diminished responsibility?
Coroners and Justice Act 2009
What was the name of the report put forward by the Law Commission?
‘Murder, Manslaughter and Infanticide’ (2006)
In their report what did the Law Commission recommend about the definition of diminished responsibility?
They recommended that the definition of diminished responsibility should be modernised so as to take into account changing medical knowledge
How has the change in the phrase of ‘recognised medical condition’ affected the law?
The definition is now flexible enough to allow for future developments in medical knowledge
What are 2 areas where difficulties remain in the defence of diminished responsibility?
(1) burden of proof
(2) developmental immaturity
What is the problem with the burden of proof in the defence of diminished responsibility?
That the burden of proof should not be on the defendant as this is a major disadvantage and could be a breach of Article 6(2) which states that ‘everyone charged with a criminal offence shall be presumed to be innocent until proven guilty according to law’
What did the Law Commission recommend about developmental immaturity?
In its 2006 report the Law Commission recommended that developmental immaturity in those under 18 should also be included within the definition of diminished responsibility
