The core principles of a criminal liability (actus reus, mens rea, specific and general defences, participation) Flashcards
What is the standard of proof for a criminal conviction?
Beyond reasonable doubt.
The prosecution has both the legal and evidential burden of proof.
Defendant only has BoP in diminished responsibility - this is lower BoP
What is necessary to establish criminal liability
- AR
- MR
- Absence of a defence
When might an omission to act result in a conviction
General rule - no liability for omissions
Exception - where D is under a positive duty to act.
1- when there is a relevant statutory offence
2- when there is a duty of care in place such as between doctors and patients, lifeguards.
3 - when there is a special relationship either by family ties or by D assuming a duty.
4 - when the defendant has created a dangerous situation.
What is the test for factual causation
The but for test.
“but for” the defendants actions would the consequence have occurred.
The defendant’s act must accelerate death
What is the test for legal causation?
The defendant’s actions must be the substantial and operating cause of the consequence.
- the consequence must be attributable to a culpable act or omission
- the act must be a more than minimal cause of the consequence
- the act need not be the sole cause
What does ‘take your victim as you find them mean”
If the victim has a predisposed weakness or religious belief which prevents them from seeking treatment or causes their harm to be more severe, this has no impact on the case. D will still be guilty.
Name 3 ways the chain of causation may be broken
- the victim acts in a particular way
- a third party acts in a particular way
- some event occurs between the D’s conduct and end result
1 - victim’s acts must be free, deliberate and informed.
Voluntary euthanasia doesn’t necessarily break the chain of causation.
2 - D will not be liable if the third party’s act is free, deliberate and informed or not reasonably foreseeable
Medical negligence - public policy not normally the case. Exception - if injuries had mostly healed. The cause was medical treatment which was ‘so palpably wrong’. If the original injury is still operating at the time of death D will be liable. Must be so independent of D’s actions and so potent in causing death.
3 - an act of god might break the chain - unforseeability of the event is the factor.
What is direct intention?
Where the outcome was D’s main aim or purpose
What is indirect intent?
- Where the Consequence was virtually certain to occur’ and
- Defendant foresaw the consequences as virtually certain
What test do the jury apply when considering whether the defendant foresaw their actions (indirect intent)
(a) Test what he himself foresaw not what the reasonable person would have foreseen, but
(b) What reasonable person would have foreseen is good indication
What is the test for recklessness?
Whether the defendant foresaw the risk of causing some harm and whether, in the circumstances known to the defendant, it was an unreasonable risk to take.
Social utility and benefit will be considered.
This is a subjective test - must look through D’s eyes
Give an example of an offence by which negligence can lead to criminal liability.
Careless and inconsiderate driving.
Negligence is an objective test. The accused will be compared against the standard of the reasonable driver. If you fall below this standard you are guilty and their motive is irrelevant.
What is strict liability?
There is no MR - conduct alone will lead to a guilty conviction.
If statute says nothing, the starting point is there is a presumption in favour of mens rea however this presumption can be rebutted.
What is the doctrine of transferred malice?
If the Actus Reus is the same as the original action then the AR and MR match up, so defendant is liable.
If the act is different to the one originally intended then malice will not be transferred.
However where the MR of an offence includes recklessness then transferred malice is not required to be considered.
Does the defendant need the MR for the whole of a continuing act.
No, D does not need the MR at the start of the act, just at some point of the continuing act.
What is a crime of basic intent?
Those committed either intentionally or recklessly
What is a crime of specific intent?
One that can only be committed intentionally
What is a crime of ulterior intent?
Where an ‘ulterior’ MR needs to also be established. Such as burglary, the burglar must have knowledge or be reckless as to being a trespasser AND have intent to steal or cause GBH.
What is the AR and MR for simple assault?
s39 CIA 1988
AR - acts or words causing the victim to apprehend immediate and unlawful personal force
MR - intention or recklessness as to the victim apprehending such force.
Silence can amount to assault.
Must be immediate and person must be present when the words are spoken.
Conditional threats might not be immediate.
What is the AR and MR for battery?
AR - infliction of unlawful personal force
MR - intentionally or recklessly applying the force
The force can be applied indirectly by throwing something. Degree of force can be light - even slight touching.
No need to show intent or recklessness as to causing any injury.
What is the AR and MR for an offence under s47 OAPA 1861 (ABH)
AR - simple / physical assault causing ABH
MR - intention or reckless as to the assault - there is no need for D to foresee ABH.
What is ABH?
Any hurt calculated to interfere with the health or comfort of the victim. Must be more than transient or trifling.
Psychological harm can be ABH if it is a recognised medical condition.
What is the AR and MR for causing GBH under s20 OAPA 1861
AR - Wound or inflict GBH a
MR - maliciously - so intent/reckless - Savage/Parmenter only needs to be reckless to some bodily harm ABH not GBH
Define GBH
really serious harm’ e.g a fractured skull or severe internal injuries.
Define wound
The breaking of both layers of skin resulting in bleeding.
What is the AR and MR for an offence under s18 OAPA 1861?
AR - Wound or inflict GBH
MR - intent to cause GBH
Intent to resist or prevent arrest and intention / recklessness as to ABH
