HOMICIDE OFFENCES Flashcards
MURDER
- Cause (applying the tests of factual and legal causation discussed previously)
- The death of another human being (Note: killing an ani-mal is never murder)
- ***Unlawfully **(for example, killing a soldier in a legally sanctioned war would not be murder)
- With the intention to** kill or cause grievous bodily harm**.
- The distinction between murder and other homicide offences is important, as murder carries a mandatory sentence of life imprisonment. If a jury convicts a defendant of murder, the judge has no discretion but to sentence the defendant to life
imprisonment.
types of homicide offences
- murder
- manslaughter
Physical Act of murder
The defendant must cause the death of a human being. This can be by action or by inaction in the case of a defendant who has a duty to care for the victim.
Foetus Not a Human Being for Purposes of Murder
For the purposes of murder, a foetus is not a human being. In English law, a person must be “fully expelled from the womb” and alive.
Death Equals Brain Dead
Death occurs when the victim is medically brain dead.
Mens Rea of Murder
The mens rea required is either intention to** kill** another human being or intention to cause grievous bodily harm **to another
human being
Types of Manslaughter
- voluntary manslaughter
- involuntary manslaughter
Voluntary Manslaughter
definition
Voluntary manslaughter occurs where the actus reus and mens rea of murder are made out (so when a defendant causes the death of another person and intends to kill or cause grievous bodily harm), but there are partial defences that can reduce the offence from murder to manslaughter. The two most common partial defences are** diminished re-sponsibility** and loss of control.
Diminished Responsibility
*The defendant must demonstrate an abnormality of mental functioning;
*The abnormality must have arisen from a recognised medical condition (note that this is broad and could include depression, Alcohol Dependency Syndrome, or even premenstrual stress);
*The abnormality must have substantially impaired the defendant’s ability to:
*Understand the nature of their conduct;
*Form a rational judgment; or
*Exercise self-control; and
*The abnormality must provide an** explanation** of the killing.
The burden of proof for diminished responsibility is reversed, and the defendant must prove each element to the civil standard (that is, on the balance of probabilities).
Loss of Control
- Their role in the killing resulted from a loss of self-control(that is, the defendant must be unable to restrain them-selves);
- The loss of self-control was caused by a** qualifying trig-ger, namely:
* A fear **of serious violence from the victim against the defendant or another identifed person; or
*A thing or things done or said which constituted circumstances of an extremely grave character and caused the defendant to have** a justifable sense of being seriously wronged; a**nd
*A hypothetical person of the defendant’s age and sex might have reacted in the same way. - If a judge is satisfed that there is sufficient evidence that the elements of loss of self-control are made out, the prosecution bear the burden to prove **beyond a reasonable doubt **that the defendant did not lose self-control.
- If the prosecution cannot disprove this, the defendant will be guilty of manslaughter rather than murder.
What Constitutes a Trigger?
- no clear definition
- revenge is not a trigger
- infidelity alone is not a trigger
Involuntary Manslaughter
definition
If the** mens rea of murder is not made out** (so the defendant does not intend to cause death or serious harm), the defen-dant may still be liable for involuntary manslaughter. Unlawful act manslaughter and gross negligence manslaughter are both examples of involuntary manslaughter.
Unlawful Act Manslaughter
In the case of unlawful act manslaughter (sometimes known as constructive manslaughter), the defendant commits a** crim-inal ofence** that carries an objective risk to the victim and they die as a result. The act must be:
*Intentional;
*Unlawful (that is, there must be an underlying criminal ofence, such as battery or criminal damage);
*Dangerous; and
*The cause of death (applying the tests of factual and legal causation)
An unlawful act is required to satisfy the offence; unlawful act manslaughter** cannot be committed by omission.**
Gross Negligence Manslaughter
Gross Negligence Manslaughter
Gross negligence manslaughter covers cases in which a de-fendant does not commit an ofence or knowingly take a risk but, rather, acts in such an extremely negligent way that they are criminally culpable.
Elements
*The defendant owes the victim a duty of care;
*The defendant breached the duty of care;
*The breach caused the victim’s death;
*There was **a serious and obvious risk **of death; and
*The breach amounted to gross negligence.
Failure to Act May Be Suffcient
gross negligence
Unlike unlawful act manslaughter, gross negligence does not need to be a positive act and can result from failing to act when a duty to assist arises.
