Module 13, Section A - Fatal offences against the person (Voluntary manslaughter) Flashcards
(43 cards)
What is diminished responsibility?
Diminished responsibility is when a defendant, though guilty of murder, will receive a reduced sentence due to an abnormality of mind that substantially impaired their ability to understand their actions or exercise self-control at the time of the murder.
What is voluntary manslaughter?
A killing where the defendant had the intent for murder but a partial defence, such as diminished responsibility or loss of control, reduces liability.
Where is diminished responsibility currently found, and what is the burden of proof?
Currently found in the Homicide Act 1957
> Burden of proof is on D to prove DR on the balance of probabilities
What does the Homicide Act 1957 state surrounding diminished responsibility?
- D suffered from an abnormality of mind
- Abnormality was caused in one of three ways
- Abnormality was a substantial cause
- Abnormality substantially impaired D’s mental responsibility
What is an ‘abnormality of mind’?
A state of mind so different from an ordinary human that the reasonable man would term it abnormal
What was the legal outcome in Anthony Martin (2001)?
Court quashed the murder conviction and substituted it with manslaughter on the grounds of diminished responsibility.
- Psychiatric evidence showed Martin had paranoid personality disorder, which substantially impaired his mental responsibility at the time of the killing.
What was the legal outcome of R v Byrne (1960)?
Diminished responsibility covers all activities of the mind – the capacity to make rational judgements and to exercise willpower can be used for DR.
What was the legal outcome of R v Seers (1984)?
Abnormality of the mind does not have to be connected with madness
What are the three ‘specified causes’ from the Homicide Act 1957?
- Arrested development (mental deficiency)
- Induced by disease
- Induced by injury
What was the outcome of Speake (1984) (arrested development; mental deficiency)
The court ruled that mental deficiency qualified as an abnormality of mind, particularly under the category of “arrested or retarded development of mind” mentioned in the Act.
What was the outcome of Gomez (1964)?
The Court of Appeal accepted that a severe personality disorder could amount to an “abnormality of mind” under the diminished responsibility defence.
What are the parameters around the ‘induced by disease’ clause in the Homicide Act 1957?
Disease can be a physical or mental disease; does not need to be physical damage to the brain (i.e. battered woman syndrome; Ahluwalia)
What was the legal outcome in Ahluwalia?
Ahluwalia appealed the conviction on the basis of diminished responsibility.
- Psychiatric evidence was introduced, showing she suffered from depressive disorder and what would later be understood as battered woman syndrome, which substantially impaired her mental functioning at the time of the killing.
Court quashed her murder conviction, later convicted of voluntary manslaughter on the grounds of diminished responsibility.
What are the parameters around the ‘induced by injury’ clause in the Homicide Act 1957?
Injury is a physical blow to the head; must have affected the physical structure of the brain; short term effects are NOT injuries
For the clause in the Homicide Act 1957 requiring the abnormality must be the substantial (most significant) cause of death, what problems can arise?
- Alcoholism and drug use (which was more influential?)
What was the legal outcome in Fenton?
The issue of whether it was the drink or the abnormality that caused the killing should be left to the jury.
Voluntary intoxication does not automatically rule out diminished responsibility.
- But the jury must decide if the abnormality alone, or together with drink, was what substantially impaired the defendant’s mental responsibility.
What was the legal outcome in Gittens (1984)?
…the court said the jurors should “ask yourselves what was the substantial cause of death”; If it was the abnormality, then the defence of DR will be established”
In terms of alcoholism, what is its effect on diminished responsibility?
If the long term alcoholism has affected the physical structure of the brain, this may be an abnormality induced by injury.
What was the legal outcome of Tandy (1989)?
… if it is long term alcoholism, we need to consider if the alcoholism amounts to abnormality induced by disease or injury
What was the legal outcome of Inseal (1992)?
… if D cannot resist drinking (involuntary), this is an abnormality induced by disease
> (Inseal chose to drink)
What was the legal outcome in Di Duca (1959)?
… court held that the effects of short term drinking on the brain were not an injury, and that alcohol had not been the substantial cause.
Knowing that abnormality must have substantially impaired D’s mental responsibility for diminished responsibility, what was the legal outcome in Lloyd (1967)?
… the court said that the mind does not need to be totally destroyed, but must be more than minimal
What is loss of control?
A partial defence to murder under the Coroners and Justice Act 2009, where the defendant acts in a sudden or gradual loss of self-control due to a qualifying trigger.
What is provocation?
An old defence under the Homicide Act 1957 that allowed a murder charge to be reduced if the defendant was provoked. It has now been replaced by the loss of control defence.
