Homicide Offences Flashcards
Different homicide offences
Murder (inc. voluntary manslaughter if partial defences apply)
Involuntary manslaughter
Corporate Manslaughter and Homicide Act 2007
Murder (common law offence)
AR: D must cause: - unlawful killing (R v Coke) - of a human being (not unborn children (Poulton)) - under the Queen's peace (R v Coke)
MR:
Murder with malice aforethought (Homicide Act 1957)
- intention to kill; or
- intention to cause GBH;
- NOT recklessness (R v Moloney)
- Irrelevant if D kills with benevolent intentions (ie mercy killings)
Death occurs when there has been irreversible death of the brain stem
R v Malcherek and Steel
What is causation?
Ds act/omission must accelerate death and be a substantial/significant cause of death
If partial defences to murder apply…
…offence will be reduced to voluntary manslaughter
Factual causation
Up to jury to determine
- ‘but for Ds actions, victim would not have died as and when he did’ (R v White)
- Acceleration must be significant (more than minimal (R v Cheshire))
Legal causation
No legal causation if:
- event intervenes between Ds conduct and end result, unless event was foreseen/foreseeable
- act by another person intervenes between Ds conduct and end result unless injuries inflicted by D still ‘operating and substantial’ cause
Ds acts need not be sole cause of victims death (for legal causation)
- it need only contribute significantly
- Can be multiple defendants
R v Pagett
Take victim as you find them
R v Blaue
Medical negligence will only break legal causation if ‘so independent of the Ds acts, and in itself so potent in causing death, that Ds acts were insignificant contribution to death’
R v Cheshire
Possible defence of intoxication for murder
Must distinguish between involuntary and voluntary intoxication
Involuntary intoxication
D had no knowledge of consumption of alcohol/drug
- including administered drug which produces adverse effects (R v Hardie)
If MR absent, may succeed as defence for murder, voluntary manslaughter or constructive manslaughter
Voluntary intoxication
Anything not involuntary, including if D knew they were drinking but underestimated effect (R v Allen)
If MR is absent, will only succeed for crimes of specific intent ie. murder and voluntary manslaughter
For involuntary intoxication, even if MR is present, D may get a reduced sentence with this defence
R v Kingston
Voluntary Manslaughter
Offence of murder can be reduced to VM if partial defence of diminished responsibility OR loss of control are present
Burden of proof on D on balance of probabilities
