Unlawful killing of a human where AR has taken place but without the MR for murder
D does not have the intention to kill or cause really serious harm, D has intent for another underlying unlawful and dangerous act
Can be a property offence (Goodfellow - Arson)
Criminal damage (DPP v Newbury and Jones)
Unlawful act:
Civil wrongdoing is not sufficient must be a criminal act
Franklin - 'mere fact of a civil wrong ought not to be used as a necessary step in a criminal case'
If the prosecution cannot establish the underlying criminal offence, then there is no possibility of UDA, even if a dangerous act
R v Lamb - not assault
AR must be a positive action, not an omission (Lowe)
Mens rea:
Prosecution must prove that D had the MR for the underlying unlawful act
SL - Andrews
Can be intent or recklessness
No MR required in relation to the death
Not necessary for D to realise
Aspect is objectively obsessed (DPP v Newbury and Jones)
Endorsed in R v Farnon and Ellis
Dangerousness:
Something that 'is likely to injure another person' (Larken)
It must be objectively dangerous (POV of bystander)
R v Church - 'all sober and reasonable person would recognise... risk of some harm, albeit not serious harm'
No need for person to foresee the actual 'type' of harm that results, just that some physical harm was possible (R v JM and SM - no need to see specific harm of rupturing artery)
Just causing fear or apprehension is not sufficient, even where it results in a heart attack (R v Dawson)
Pre-existing knowledge:
When determining dangerousness, consideration of Ds pre-existing knowledge about V/situation and any knowledge that D acquires during the commission of the unlawful act, such as knowledge of danger (R v Fardon and Ellis - circumstances known to D)
Confirmed in R v Long, Bowers and Cole - act in the circumstances was dangerous
Dangerous act need not be aimed at V that dies:
R v Mitchell - 'innocent agent'
R v Larkin - 'act likely to injure another person, and quite inadvertently he causes the death of that other person by that act'
Against property:
Can be aimed at property - 'risk of some (physical) harm'
R v Goodfellow - set fire to the property in attempt to move
Causing the death:
Final element is proof that the unlawful act caused the death
Must be a proven casual link between the act and the death (R v mitchell)
Where there is an intervening act that breaks the chain of causation, D cannot be liable (R v Cato - D injected drug into V)
Contrasted in R v Dalby, injecting themselves broke the chain (Confirmed in R v Dias and upheld in Kennedy)
