fatal offences - murder Flashcards
What type of offence is murder?
A common law homicide offence which means that the offence is not defined by any Act of Parliament
Who gave a definition of murder in the 17th century and what was the definition?
Edward Coke - The unlawful killing of a reasonable person(human being) in being and under the King’s peace with malice aforethought express or implied
What three things are needed to establish murder?
Actus reus
Causation
Mens rea
What are the 4 elements of the actus reus when it comes to murder?
The defendant killed
The killing was an unlawful killing
Reasonable creature
King’s peace
What is meant by ‘the defendant killed’ in terms of an element of the actus reus for murder?
The killing must be a voluntary positive act or an omission.
What is meant by ‘the killing was an unlawful killing’ in terms of an element of the actus reus for murder?
is there a defence to apply to the offence? usually not but needs to be mentioned - loss of control, duress, intoxication, diminished responsibility
What is meant by ‘reasonable creature’ in terms of an element of the actus reus for murder?
means a human being - for murder a living person must be killed
What are the rules for ‘reasonable creature’ for the actus reus for murder surrounding unborn children?
The D can’t be charged with murder in respect of killing a fetus but the Infant Life (Preservation) Act 1929 sets out that the D can’t kill a unborn but viable feotus
In terms of unborn children, when would it be seen that the child is a human being?
The child has to have an existence independent of the mother for it to be considered a creature if being. This means it must have been expelled from her body
What is meant by ‘king’s peace’ in terms of an element of the actus reus for murder?
The killing of an enemy soldier during a war is not a murder as the king is at war
What is meant by causation in relation to murder?
Murder is a result crime therefore the D can’t be found guilty unless his act or omission caused the death
What are the two types of causation?
Factual
Legal
What is meant by Factual causation and name two cases to support it:
The D can only be guilty of the consequence would not have happened ‘but for’ the defendant’s conduct: R v white & R v Pagett
What happened in the case of R v White?
White put potassium sionide in his mothers drink before bed trying to kill her to gain the inheritance money. His mother died of an unrelated heart attack therefore his actions didn’t cause her death and he couldn’t be charged with murder
What happened in the case of R v Pagett?
D used his pregnant girlfriend as a human shield when police were trying to arrest him for shooting her father and kidnapping her mother. A police sniper shot and killed D’s gf by accident. It was held that ‘but for’ the actions of the D, his gf would not have died
What are the two issues that need to be addressed by legal causation?
-Is the D’s action more than a minimal cause of the death (De minimis rule):Kimsey
-Is D’s conduct a substantial cause of the death. Was the actions of the D the operating cause of the death: R v Smith
What happened in the case of R v Smith?
Soldier was in a fight and was stabbed. His colleagues took him to a medic but dropped him several times of the way. The doctor failed to diagnose a punctured lung and the soldier died - it was held that the stab wound was the operating cause of death
What is meant by Novus actus Interveniens?
intervening acts - something may happen between the actions of the D and the death of the V and it needs to be established who is the ‘actual’ cause of the V’s death
What are the two intervening acts that may be considered in a murder?
medical treatment
Victims own acts
How likely is medical treatment to break the chain of causation and why is this?
Suggesting that medical treatment might break the chain of causation is contentious because he the D not harmed the V in the first place, he would not have ended up in hospital. Medical treatment is most unlikely to break the chain of causation
When will medical treatment break the chain of causation? Give a case example:
If the medical treatment is so overwhelming/palpably wrong as to make the original wound a mere part of the case history, would it be an novus actus interveniens: R v Jordan
What case shows when medical treatment would not break the chain of causation?
R v Cheshire
What happened in the case of R v Jordan?
Jordan stabbed a man who died of pneumonia following the abdominal injury sustained. The V was intolerant to the drug which was being given to him at the hospital before the doctors realised this and stopped the treatment. The next day a new doctor started this drug again in abnormal quantities which waterlogged the V’s lungs - the treatment was so independent from the initial wound that it broke the chain of causation
What happened in the case R v Cheshire?
A V was being treated after being shot. The doctor inserted a tracheotomy tube to improve the V’s conditions. 4 weeks later it was removed but several days after, the v was having respiratory issues due to the narrowing of his windpipe - the medical care was necessary because of the wound V had due to D’s actions therefore the treatment wasn’t the substantial cause of the V’s death
