1B.2.1 Murder Flashcards
What is homicide?
Homicide is the unlawful killing of a human being.
There are different offences of homicide, depending on the mens rea and whether there is a special defence available to the defendant.
Homicide offences include
Murder
Voluntary Manslaughter
- Diminished Responsibility
- Loss of Control
Involuntary Manslaughter
- Gross Negligence Manslaughter
- Unlawful Dangerous Act Manslaughter
Murder
Murder is the most serious of the fatal offences. This is reflected in the sentence for a conviction for murder being mandatory life imprisonment.
Murder is a common law offence – it is not defined by any Act of Parliament. It has been defined by the decisions of judges in different cases, and the accepted definition is based on one given by a seventeenth century judge, Lord Coke
Lord Coke’s definition of Murder
- “The unlawful killing of a reasonable person in being and under the King’s Peace with malice aforethought, express or implied.”
What does the jurisdiction of murder cover?
- Any murder committed by a British citizen in England and Wales
- Any murder in any country by a British citizen
Therefore, if the defendant is a British citizen, they may be tried in an English court for a murder they are alleged to have committed in another country.
Actus Reus for murder
Key components to satisfy the Actus Reus:
- The defendant killed,
- The victim was a reasonable creature in being,
- Under the Queen’s Peace,
- The killing was unlawful.
Actus Reus: ‘Killed’
The AR can be fulfilled by an act or omission (failure to act) but this must cause the death of the victim.
The defendant cannot be guilty of murder unless their act or omission caused the death. In most cases there is no problem with this. For example, the defendant shoots the victim in the head and the victim is killed instantly.
However, there might be other causes contributing to the death, such as poor medical treatment. This type of situation raises questions of causation, which can be seen in the cases of R v Smith (1959) and R v Jordan (1956) – which relate to the offence of murder.
Example of an omission for the AR of murder.
R v Gibbins and Proctor: Father & mistress of a 7-year-old girl deliberately starved her to death. The omission/failure to feed her was deliberate with the intention of killing or causing serious harm to her. Held: The failure to feed (omission) was enough for the actus reus of Murder.
Causing the death
- The ‘unlawful act’ must cause the death.
To be liable:
1) The defendant’s conduct was the factual cause of that consequence;
2) It was the legal cause of that consequence; and
3) There was no intervening act which broke the chain of causation
Factual cause
- The defendant can only be found guilty if the consequence would not have happened “but for” the defendant’s conduct.
- “but for” test – R v Pagett (1983)
Legal cause
- The defendant can only be found guilty if their conduct was more than a “minimal” cause of the consequence. But the defendant’s conduct need not be a substantial cause.
- “more than a slight or trifling link”– R v Kimsey (1996)
- Thin Skull Rule: The defendant must take the victim as he finds him (R v Blaue (1975))
- Multiple causes: The defendant can still be guilty even if his conduct was not the only cause of the death. (Kimsey)
Intervening act which breaks the chain of causation
(Novus acus interveniens)
- This point has caused problems in cases where the defendant has supplied the victim with an illegal drug.
- However, if the defendant also injects the drug into the victim, then there is no break in the chain of causation.
The chain of causation can be broken by:
- An act of a third party
- The victim’s own act, or
- a natural but unpredictable event
- Intervening act must be sufficiently independent of the defendant’s conduct and sufficiently serious.
Actus Reus: ‘Reasonable creature in being’
The phrase means ‘a human being’. So, for murder, a person must be killed.
In Attorney-General’s Reference (No 3 of 1994)(1997), it was stated by the House of Lords that a foetus is not a reasonable creature in being, because it is not independent of its mother.
It is not certain whether a person who is ‘brain dead’ would be considered as a ‘reasonable creature in being’ or not. However, doctors are allowed to switch off life-support machines without being liable for murder or manslaughter.
Actus Reus: ‘Under the King’s Peace’
‘Under the King’s Peace’ means that killing an enemy in the course of war is not murder. However, killing a prisoner of war would be sufficient for the actus reus of murder.
Actus Reus: ‘Unlawful’
The killing must be unlawful.
The killing is not unlawful if it is:
- in self-defence
- in defence of another
- in the line of duty
