conduct crimes
doing- what matters is what defendant does e.g. drink driving. no consequence is required, the AR is the prohibited conduct itself
consequence crimes
result- the AR must result in a consequence, e.g. assault
state of affairs crime
circumstances- what matters is being there in the prohibited circumstances, e.g. being in possession of a controlled drug, the D doesn’t have anything to do with the drug but is still in possession of it
omission
the general rule in criminal law is that a person is not liable for an omission (failure to act) unless under a duty to act
statutory duties and common law duties
examples of statutory duties
contractual duties
arise through contracts of employment, e.g pittwood 1902- where a railway crossing keeper had a duty of close the gate, his omission formed the AR of manslaughter
official position
usually related to public office, e.g. Dytham 1979- where a police officer stood by while V was getting beaten up. D was guilty for failing to perform his duty while in a public position
special relationship
e.g. Gibbins + Proctor 1918 , where a father starved his 7 year old daughter to death. he had a duty to feed her and the omission formed the AR of murder
duty undertaken voluntarily
based on reliance, e.g. Stone + Dobinson 1977 where D’s took in an elderly relative and failed to look after her. D’s were liable for her death
creating a dangerous situation
e.g. miller 1983- where D failed to take reasonable steps to deal with the fire he had started. he had created a dangerous situation and owed a duty to call the fire brigade. he was therefore liable when he failed to do so
Airedale NHS trust vs Bland 1993
there can be cases where doctors decide to stop treating a patient. if discontinuing treatment is in the best interests of the patient then it is not an omission so doesn’t form the AR
causation
an essential element to establish the AR in consequence crimes. there needs to be evidence to show that the D caused the consequence
chain of causation
the prosecution has to prove:
1. D’s conduct was the factual cause of the consequence;
2. it was the legal cause of that consequence, and
3. there was no intervening act which broke the “chain of causation”
factual causation
this is the starting point in establishing the “chain of causation”. it must be proved that the unlawful consequence wouldn’t have happened “but for” D’s conduct
Pagett 1983
D was the factual cause of death when he used his girlfriend as a shield and fired at police. she wouldn’t have died “but for” his actions
White 1910
D was acquitted because although he tried to poison his mother, she actually died because of a heart attack, so he wasn’t a factual cause
legal causation
there may be more than one act contributing to the consequence. some of these acts may be made by people other than D. the key rule is that D’s conduct doesn’t need to be the only cause of the consequence. D’s contribution must be more than minimal
Kimsey 1996
D and V engaged in a high speed car chase. V lost control of the car and died. the trial judge directed the jury that D’s driving didn’t have to be “the principal, or a substantial cause of death, as long as you are sure that it was a cause and that there were something more than a slight or trifling link.”
Benge 1846
D was a foreman during work on a train track. he failed to give adequate warning to an approaching train driver and a fatal accident occurred. it was irrelevant that the accident might have been avoided if others hadn’t also been negligent. D substantially caused the death through his negligence
thin skull rule
means that the defendant must take the victim as he or she finds them
Blaue 1975
D was responsible for V’s death when the Jehovah’s witness he stabbed refused a blood transfusion, despite the fact she would have survived if she had accepted the treatment
intervening acts
an intervening act may operate to “break the chain of causation” and prevent D from being liable for the ultimate result, even if D’s conduct was a factual and more than minimal cause.
the chain of causation was broken by:
- an unforeseeable act of nature
- the unforeseeable act of a third party
- V’s own subsequent conduct
victim’s own conduct
if D causes V to act in a foreseeable way, then V’s own act will not break the chain of causation
