Unit 3 - Murder Flashcards
(32 cards)
What does homicide mean?
It is a generic term for unlawful killings where the defendant is criminally liable for a victims death.
What are the different types of mansalughter?
Voluntary, unlawful act, gross negligence and corporate
What is the actus reus common to all homicide offences?
The accused has caused the death of a human being. This is often easily proven.
What are the conditions for the actus reus of homicide?
THE VICTIM MUST BE A HUMAN BEING. must be legally recognised as a human being. For a foetus, this has been determined in R v Poulton, where it must be wholly expelled from the mother’s body, alive and have an existence independent of the mother (drawn breath).
What matters most in cases where someone hurts a foetus inside the womb?
The time of death (whether it was outside of womb); and not the time of injury.
What did the case of R v Malcherek and Steel 1981 determine - legal definition of death?
It established the legal definition of death as: the irreversible death of the brain stem. Once the brain stem death occurs, the body is legally considered dead even on life support.
Does causation and life support conflict?
No, disconnecting life support from someone brain dead does not break the chain of causation.
How is causation measured?
Same as others. Factual and legal causation.
What is the conviction for murder?
Mandatory life sentence, but there is a minimum term after which they may be released.
What is the men’s Rea for murder?
R v Maloney: either an intention to kill or an intention to cause gbh. The test of intention is subjective.
Can intention for men’s Rea of murder be direct or indirect?
Direct: Maloney - the defendant desired the outcome as their aim or purpose
Indirect: the defendants primary aim was something else but they foresaw the death or GbH as a virtually certain consequence.
What is the difference between voluntary and involuntary manslaughter?
Voluntary: where the defendant has the men’s Rea for murder but successfully raised a partial defence.
Involuntary: where the defendant does not have the men’s Rea for murder but causes death due to a criminal act/ gross negligence.
What are the three partial defences for murder (only) that reduce a charge to voluntary manslaughter?
Diminished responsibility
Loss of control
Suicidal pact
What is the defence for diminished responsibility?
Although they have the AR and MR, they were suffering from a recognised medical condition. The legal burden to prove this is on the defendant (on the balance of probabilities).
What must the defence prove in a diminished responsibility case?
An abnormality of mental functioning, which; b. Arose from a recognised medical condition; and c. Substantially impaired the d’s ability to understand the nature of their conduct, and or form a rational judgement/ exercise self control; and d. Provides an explanation for the defendants acts and omissions.
What must be the case for the partial defence of diminished responsibility to succeed?
The abnormality must have been at least a significant contributory factor in causing the defendant to do as he did. It need not be the only, main or most important factor, but must be more than merely trivial.
What the Dietschmann case show about diminished responsibility?
The abnormality of mind did not need to be the sole cause of the defendants acts. The jury considers if the abnormality substantially impaired mental responsibility despite being intoxicated. Can be both.
What is the links between intoxication and diminished responsibility defence??
R v Dowds: voluntary acute intoxication cannot form the basis of diminished responsibility.
R v Wood: voluntary alcohol consumption does not automatically stop a diminished responsibility plea if they have an alcohol dependence. The jury should focus exclusively on the alcohol consumed as a result of their illness and not the effect of any alcohol consumed voluntarily.
DR defence: what does “substantial impairment” mean?
“Important or weighty”. A minor impairment is insufficient.
What is the causal link for diminished responsibility?
The abnormality of mental functioning must be a significant contributory factor in causing the victims contact, but need not be the only factor (more than trivial).
What is the insanity defence?
It is a complete defence.
What does the partial defense of loss of control cover?
Acknowledges that individuals have a breaking point where they lose self-control due to extreme circumstances
What are the three key elements of a loss of control defence?
ALL 3 MUST BE SATISFIED
1. The d must have lost control
2. The loss of control must have had a qualifying trigger
3. A person of the defendants sex and age with a normal degree of tolerance and self restraint in the circumstances of the defendant might have reacted in a similar way.
Loss of control: need the reaction be a sudden one?
No, this helps in cases of a build up of emotion like domestic violence. The greater the deliberation, the less likely it will be deemed a loss of control.
