Criminal Conduct Flashcards
offences of strict liability
do not require proof of any mens rea
How can the actus reus be committed?
General rule: via positive act
Exception: via an omission to act - but only where there is a breach of a duty of care
Voluntary actions only
The actus reus must be committed voluntarily, i.e. the act or omission must be under a person’s own free will.
Involuntary actions
No liability
A physical compulsion to act
A pushes B and B accidentally clashes head with C - breaking C’s nose. B will not have committed assault
A sudden lose of control
A loss of self-control that is both sudden and unexpected, e.g. cramp, blackout
Forseeable involuntary acts
no defence
Consequences if an involuntary act is forseeable?
if the onset of the impairment could reasonably be foreseen or anticipated due to a pattern or previous similar incidents - then the actions will be deemed voluntary despite the inability to control the impairment of the defendant’s actions, e.g. diagnosed narcoleptic falling asleep at the wheel
Establishing a causal link
prove a causal link between the act/omission and the relevant consequrnce
The “but for” test
“But for the defendant’s act or omission would the consequence have arisen?”
Does the act/omission need to be the sole cause of the consequence?
No, it just needs to be the operating and substantial (main) cause of the consequence
The Eggshell Skull Rule
Take the victim as you find them
R v Harvey (2010)
Threw remote > ruptured weak neck artery > death
R v Watson (1989)
Burglary > Frail - 87 > Heart attack > Death
R v Mckechnie (1992)
Stomach ulcer > Brain damage in assault - preventing surgery on the ulcer > stomach ulcer ruptures > death
When will an intervening act break the chain of causation?
The chain of causation can be broke by a new intervening act - provided the new act both: is free, deliberate and informed - R v Latif (1996) or becomes the operating and substantial cause of the death
Breaking the chain of causation
initial act/omission>intervening act relevant consequence
Accepted medical practice for treating injuries - chain not broken
R v Smith (1959) - Assault causing injuries > accepted treatment > injuries from attack cause death
Treatment that is wholly inconsistent with accepted medical practice - chain is broken
Treat will break the chain of causation. R v Jordan (1956): stabbed > drug treatment>drug caused death
Anticipated actions by the victim
The actions of a victim will not break the chain of causation - if they are those which might reasonably be anticipated from a victim placed in such a situation
Daft voluntary actions by the victim
The actions of the victim will break the chain of causation - they are both: voluntary i.e. not a forced response to the situation they were placed in; and daft (R v Williams (1992))
Will a victim’s refusal to accept medical treatment on the grounds of their religious beliefs breaks the chain of causation?
No. R V Blaue (1975): Assault causing injuries> Transfusion refused on religious grounds> Injuries from attack cause death
Addict self-administers - addict breaks the chain of causation - No manslaughter
R v Kennedy (2007): Dealer supplies> Addict self administers (main cause of death> chain broken > addict overdoses
Dealer helps to administer - chain present - manslaughter
R v Dias (2001): Dealer supplies > Dealer helps to administer (main cause of death) chain present > Addict overdoses
WHEN WILL AN INTERVENING ACT BREAK THE CHAIN OF CAUSATION
If an action occurs after the initial act or omission of the defendant - you must ask yourself what is the main cause of the consequence?
If the main cause is still the defendant’s initial act or omission - then the chain of causation is not broken and the defendant will have committed the actus reus of the offence.
If events have been overtaken by the subsequent intervening act so that the intervening act becomes the main cause of the consequence - then the chain of causation is broken, and the actus reus of the offence will not have committed.
