W5 Involuntary Manslaughter Flashcards
What is involuntary manslaughter?
When victim has died, and there is a causal link between actions/omissions of D and the death, but there is no mens rea for murder.
What is constructive manslaughter?
Also called UDAD (Unlawful and Dangerous Act Manslaughter).
Offence constructed from a less serious crime.
Unlawful act + objectively dangerous + causing death = UDAM
What qualifies as an unlawful act for constructive manslaughter?
Unlawful in the criminal sense of the word - R v Lamb/ R v Kennedy (No 2)
What are the requirements for proving constructive manslaughter?
1) Establish the actus reus and mens rea of the base offence (Unlawful Act)
2) Establish that the act was objectively dangerous
3) Establish causal link between act and death
Does D have to foresee the risk of causing harm from the unlawful act?
No - R v Newbury and Jones
But does have to be objectively dangerous - R v Church
Unless D had special knowledge - Ball
R v Newbury and Jones
Facts: D threw paving stone off railway bridge, hit train and killed guard.
Significance: May be unclear what offence caused the death. Unnecessary for D to have foreseen risk of harm or known act was illegal.
R v Lamb
Facts: D pointed a revolver at friend as a joke. Didn’t know how guns worked, didn’t think there was a bullet in the chamber.
Significance: Was lacking the mens rea for the base offence (assault/battery) so not constructive manslaughter.
What is the threshold for danger for constructive manslaughter?
Unlawful act must be such that reasonable people would inevitably recognise that it would lead to the risk of some harm.
Note: Risk of harm, not likelihood of harm
Risk of some harm, not necessarily serious harm
R v Church
Facts: Knocked a woman unconscious, thought she was dead, so threw her into the river.
Significance: Constructive manslaughter - example of objectively dangerous act. Didn’t matter that he believed her to be dead.
R v Ball
Facts: D shot and killed V, but believed he had loaded the gun with blanks. He kept both live and blank cartridges in his pocket, grabbed a handful, and thought they were blanks. His belief was taken into consideration in regards to the mens rea for the base offence, but not for the objective test of danger.
Significance: Constructive manslaughter - Foreseeability of danger viewed from perspective of sober and reasonable bystander, unless D had special knowledge.
R v Dawson, Nolan, & Walmsley
Facts: Armed robbery with fake firearm. V was seemingly healthy, behind bulletproof glass, but had weak heart. Weak heart ruled not included in foreseeability of danger.
Significance: Constructive manslaughter - foreseeability of danger
R v Watson
Facts: D burgled elderly man, who died from heart attack. Ruled that the danger was foreseeable because of V’s age/frailty.
Significance: Constructive manslaughter - foreseeability of danger
Does the unlawful dangerous act have to have caused the death?
Yes. It does not need to be the sole/principal cause but must contribute. Normal causation rules apply.
What is gross negligence manslaughter?
Death resulting from grossly negligent (but otherwise lawful) act or omission.
No conscious choice to cause harm (no mens rea)
What is the legal authority for gross negligence manslaughter?
R v Adomako
