Homocide Flashcards
What is the definition of murder?
The unlawful killing of a human being under the Kings’ Peace, with malice aforethought.
What is voluntary manslaughter?
This is where the defendant has satisfied the actus reus and mens rea of murder, but murder conviction is reduced to voluntary manslaughter by way of diminished responsibility or loss of control.
What is involuntary manslaughter?
This is where the defendant has killed the victim, but lacks the mens rea of murder.
What are the special defences for murder?
Loss of control and diminished responsibility
What happens if a partial defence for murder is successful?
The accused will be convicted of voluntary manslaughter
What is the sentence for murder?
Murder carries a mandatory life sentence. The judge has no discretion in sentencing other than to recommend a minimum term before a prisoner can be released on licence.
What is the burden to prove diminished responsibility?
The burden falls upon the defence to prove on the balance of probabilities that the defendant was acting under diminished responsibility
What are the requirements to prove diminished responsibility?
If D was suffering from an abnormality of mental functioning which-
(a) arose from a recognised medical condition,
(b) substantially impaired D’s ability to do one or more of the things mentioned in
subsection (1A), and
(c) provides an explanation for D’s acts and omissions in doing or being a party to the
killing.
(1A) Those things are—
(a) to understand the nature of D’s conduct;
(b) to form a rational judgment;
(c) to exercise self-control.
(1B) For the purposes of subsection (1)(c), an abnormality of mental functioning provides an explanation for D’s conduct if it causes, or is a significant contributory factor in causing, D to carry out that conduct.
What is an ‘abnormality of mental functioning’?
‘state of mind so different from that of ordinary human beings that the reasonable man would term it abnormal’
How does Alcohol Dependency Syndrome relate to diminished responsibility?
ADS is a medically recognised condition as the ICD and DSM recognised a number of medical conditions that would give rise to significant problems if raised as issues in legal cases, including ‘unhappiness’, ‘irritability and anger’, and ‘intermittent explosive disorder’.
What does substantial impairment mean?
It had a more than merely trivial effect on D’s ability to understand the nature of D’s conduct, to form a rational judgment, to exercise self-control.
Therefore, a causal link between the abnormality of mental functioning arising from a recognised medical condition and the killing must be established.
What does diminished responsibility not apply to?
Attempted murder
Where does the burden of proof for loss of control lie?
The prosecution need to prove that only one of the components is absent for the defence to fail.
What are the requirements for a loss of control offence?
Where a person (‘D’) kills or is a party to the killing of another (‘V’), D is not to be convicted of
murder if—
(a) D’s acts and omissions in doing or being a party to the killing resulted from D’s loss of self-control,
(b) the loss of self-control had a qualifying trigger, and
(c) a person of D’s sex and age, with a normal degree of tolerance and self-restraint and
in the circumstances of D, might have reacted in the same or in a similar way to D.
What does a loss of self-control constitute?
Although there need not be a complete loss of control so that defendants do not know what they are doing, defendants must be unable to restrain themselves, a mere loss of temper would not be enough.
The loss of control need not be sudden (s 54(2)) but the defence will be lost should it be established that the defendant was acting out of a ‘considered desire for revenge’
