Sound judgement and age- D must be over the age of 10 and have mental sanity.
Unlawful killing- D’s actions or omissions must have led to the death. (Gibbins v Proctor) D must not be acting in self-defence/necessity.
5 elements of actus reus-
Reasonable creature in being- V must be a human being, capable of living and has own identity.
(A-G Ref no.31994,1997)-If baby born alive but dies, Actus Reus for manslaughter. However, Mens Rea cannot be transferred from mother to foetus.
If patient is brain dead, life support machine being switched off doesn’t break the chain of causation. Test for murder is brain death. (R v Malcherek)
King’s peace- Killing an enemy in war is not murder.
Within the nation- If D is a British citizen, they can be tried in the UK for murder committed elsewhere.
Causation-
Factual causation- ‘but for’ test, consequences would not have occurred but for D’s conduct. (R v Pagett)
Legal causation- ‘de minimis’ principle, D’s actions must be more than minimal/slight or trifling link. D doesn’t need to be substantial/principle cause. (R v Kimsey)

Malice a forethought express/implies is the mens rea of murder.
Express malice is intention to kill, the aim/purpose/desire is to kill V. (R v Mohan)
Impliedmalice is intention to cause GBH. (R v Woollin)
Oblique intent is when D foresees/realises death or serious injury as a virtual certainty. (R v Vickers)
GBH (GrievousBodily Harm) is really serious harm. (DPP v Smith)
