Criminal Law Flashcards
In criminal cases who has the burden of proving a crime has been committed? When may this burden be reversed?
The burden of proving a crime has been committed as on the prosecution. The CPS must prove it the defendant does not need to prove anything.
In some certain situations there is a reversal.
- if the defendant wishes to raise certain defences, the defendant will have the burden of proving the defence. For example if a defendant wishes to raise the defence of diminished responsibility they must prove it on the balance of probabilities.
- sometimes within the elements of the offence there is an exception that negates the offence in these offences. Once the prosecution is made out the primary evidence. It’s for the defendant to prove, on the balance of probabilities that it falls within the exception.
What is the evidential burden?
Certain defences such as self-defence, the defendant must raise for the court to consider, this is the evidential burden of proof however once the defendant raises the defence the prosecution then has the burden of proof of disproving it, this is the legal burden of proof
What is a strict liability offence?
An offence that does not have a mens rea, the offence is committed if the actus rea is complete this. includes driving without insurance and driving under the influence
When can an omission be a criminal act?
In most offences, the act is a positive act but in certain circumstances failure to act can amount to conduct.
2 requirements must be satisfied for a failure to act to amount to criminal offence:
- There must be a duty on behalf of the defendant act and
- The defendant must have breached duty by failing to act sufficiently
Duty to act may arise in a number of circumstances, including:
Under statute
Special relationship for example, parent and child or doctor
Defendant voluntary assumed a duty of care for the victim
Duty imposed by contract such as railway guard
Defendant has created a dangerous situation and they are aware that they have done so
What is a result crime?
It is a crime that requires a certain outcome for the offence to be committed.
Example - murder is a result crime whereas possession of a knife is a crime regardless of what happens to the victim so is not
For a result crime, how is causation established?
The court will apply a two stage test:
Factual causation
- but for test. Must be cause of result.
- if more than one cause or D’s action slightly accelerates the results, this is sufficient
Legal causation - prevents conviction where factual causation is met but other factors such as lack of foreseeability makes it unfair
- action must be substantial and operative cause
- substantial means must be more than minimal, slight or trifling
- operative means that if the actions of someone else intervene between defendants act the result the defendant will not be liable
When will the chain of causation be broken?
By defendant, if the intervention is a new act
By natural event, if the defendant and a reasonable person would not have foreseen the natural event
By the victim if a defendant and reasonable person would not have foreseen the victims act and the victims act is voluntary. To break the chain the actions must be so daft as to be unforeseeable however the thin skull principle applies.
Action of a third party will break the chain if the intervention is free deliberate and informed. Medical treatment is very unlikely to break the causation and will only do so if it is so independent and potent to make the original wound in the background
What is the mens rea?
It is the mental element of an offence. The state of mind must have at the time of the actus rea in order to be guilty of the offence.
It’s not a motive
What is the mens rea of intention?
Common form of men’s which applies to many different offences, including all offences against the person and murder
Can be satisfied in two ways:
Direct intention
- Most common
- intention = aim or purpose
Indirect intention
- where the prosecution can’t prove the defendant had direct intention. The court may find that the defendant had intention if the outcome is a virtual certainty of the act and the defendant realise the outcome as virtual certainty.
What is required for indirect intention?
The result of the defendants act must be:
- A virtually certain consequence of their conduct and
- Realised by the defendant as being virtually certain
Indirect intention is only available for specific intent offences (where recklessness is not available as a form of men’s) it never applies to basic intent offences.
What is a specific intent crime?
Where intention is the only form of mens rea available, they can only be committed intentionally and cannot be committed recklessly
Attempt is a specific intent crime, even if the crime attempted is not
Attempt
Encouragement and assistance
Murder
Wounding or causing GBH with intent se 18
Theft
Robbery
Burglary s9(1)(a)
Fraud by false misrepresentation
What is transferred malice?
If a defendant has the intention to commit an offence against one victim but in advertently commits the offence against a different victim, the intent is transferred to the new victim
Person found guilty of an offence on the basis of transferred malice is usually guilty of 2 offences 1) the complete offence against the actual victim and 2) the attempted offence against the intended victim
Transferred malice only applies when the offence intended is the same as the one committed. It cannot be transferred from one offence to another
What is recklessness?
Crimes of recklessness required lower level of culpability than those required for the defendant to intend the result
Recklessness requires that :
- The defendant sees the risk from the act and continues regardless (subjective, extent of risk is irrelevant) and
- In all the circumstances known to defendant it must be an unreasonable risk to take (objective)
What are recklessness crimes?
Assault
Battery
Wounding or causing GBH s20
Criminal damage
What is the test for an offence of negligence?
Even lower level of culpability than recklessness
Court asks:
1) Did the defendant of duty of care and
2) Did the defendant breach standard of care expected?
In some cases, the standard will be defined by statute and others it will be defined by common law
Always objective standard
Example careless driving
What is a strict liability offence?
There is one that does not require awareness of all the all the factors constitute in the crime.
Defendant can be found guilty on the mere fact they committed the act
No mental state required.
What is corporate liability?
A corporation can be held liable for criminal lacks however because it is distinct from owners there difficulties in prosecuting a corporation for a crime that requires a mental state.
Prosecution must find a controlling persons whose actions and mental state can be said to be that of the corporation as a whole
To fill in the gap Parliament has introduced specific offences that target corporations and do not require a mental element. These include things such as breach of health and safety standards. Liability also sometimes imputed if it fails to prevent certain offences
What is the definition of murder?
A defendant commits murder when they:
- Cause (applying factual and legal causation)
- The death of another human being
- unlawfully
- With the intention to kill or cause GBH
Carries mandatory life sentence
Can be physical act or in action if the defendant has duty of care for the victim
Is not human being for the purpose of murder
Brain dead equals dead
What are the different types of manslaughter?
Voluntary manslaughter
- where defence reduces
Involuntary manslaughter
- Unlawful manslaughter
- Gross negligence manslaughter
What is voluntary manslaughter?
Occurs where AR and MR of murder is made out but there are partial defences that can reduce the offence from murder to manslaughter
Most common diminished responsibility and loss of control
What are the requirements for a defendant to assert diminished responsibility?
Defendant must:
- Demonstrate an abnormality of mental functioning
- The abnormality must’ve risen from a recognised medical condition (broad)
- The abnormality must have substantially impaired the defendants ability to
1) understand the nature of their conduct
2) form rational judgement or
3) exercise self-control
The abnormality must provide an explanation of the killing
The burden of proof of diminished responsibility is reversed so the defendant must prove each element on the civil standard
What are the requirements for a defendant to establish loss of control?
Defendant successfully raised loss of control they must show:
- Their role in killing resulted from a loss of self-control
- The loss of self-control was caused by a qualifying trigger namely
1) fear of serious violence against the V or another person or
2) a thing or things done or said which constituted circumstances of an extremely grave character and caused a defendant to have a justifiable sense of being seriously wrong and
- A hypothetical person of the defendants age and sex might have reacted in the same way
If the judge is satisfied that the elements of loss of control are made out the prosecution must then bear the burden of prove beyond reasonable doubt that the defendant did not lose control. If the prosecution cannot do this and defendant will be guilty of manslaughter rather than murder
Definition of trigger is unclear revenge is not a sufficient trigger and sexual infidelity alone is not a trigger
What is involuntary manslaughter?
If the men’s of murder is not made out the defendant may still be liable for involuntary manslaughter
Unlawful manslaughter and gross negligence manslaughter are both examples
What is a unlawful act manslaughter?
Defendant commits a crime that carries an objective risk to the victim and they die as a result
The act must be:
- intentional
- unlawful (underlying criminal act)
- Dangerous and
- The cause of death (applying the test of factual and legal causation)
Positive act is still required to satisfy the offence and cannot be committed by omission
Must satisfy test and the act must be the substantial and operative course meaning it must be more than a minimal cause and there must be no break in the chain of causation
What is gross negligence manslaughter?
Covers cases where the defendant does not commit an offence or knowingly take a risk but acts in such an extremely negligent way that they are criminally culpable
Elements :
- The defendant owes the victim of duty of care
- The defendant breached the duty of care
- The breach caused the victims death
- There was a serious and obvious risk of death and
- The breach amounted to gross negligence
Failure to act maybe sufficient if it results from failing to act where there is a duty to assist
Breach of duty is established by comparing the defendants act to the standards of a reasonable person under that duty with the applicable expertise
