Criminal Law (Underlying) Flashcards
What are the key elements of criminal liability?
Actus Reus
Mens Rea
Absence of Valid Defence
What is the direction/test for gross negligence manslaughter?
Whether, having regard to the risk of death involved, the conduct of the defendant was so bad in all the circumstances as to amount to a criminal act or omissionsection 5(4) Theft Act 1968.
What question does the jury ask in cases of voluntary intoxication>
In cases of voluntary intoxication, a jury should consider whether the defendant would have seen the risk had he not been intoxicated.
What is a result crime?
D must cause a particular result.
For example, murder, criminal damage, ABH
Causation is part of the actus reus of result crimes
What is the correct standard of proof that the jury must apply when determining the defendant’s guilt and the validity of the self-defence claim?
The prosecution must prove the defendant’s guilt beyond reasonable doubt
The defendant must raise enough evidence to suggest self-defence applies, and then the prosecution must prove beyond reasonable doubt that it does not.
In other words, once the defence raises the possibility of self-defence, the prosecution must disprove it beyond reasonable doubt for the jury to convict the defendant.
What aspects of causation must be proved for a result crime?
Factual Causation - the acts/omissions were factually the cause of the consequence
and
Legal Causation - the acts/omissions were a legal cause
What is the factual causation test?
But for the acts or omissions of the accused, the consequences would not have occured as they did
What is the test for legal causation?
Is Ds act the operating and substantial cause of the prohibited consequence?
When proving legal causation, what are the five ‘novus actus interveniens’ and what effect do they have?
- Medical Negligence
- Acts of third parties
- Acts of the victim
- Thin skull rule
- Natural events
… Could break the chain of causation
Will medical negligence break the chain of causation?
The courts are reluctant to allow medical malpractice to break the chain of causarion
It will only break the chain if the negligent treatment is so independent that they regard the defendants contribution as insignificant.
When will the acts of a third party break the chain of causation?
Only if the acts of the third party are free, deliverate and informed.
For example, a police officer returning fire and killing a hostage is part of self-presservation and therefore not free and deliberate.
What are the three situations whereby the acts of the victim could potentially break the causal chain?
- Fright and Flight Cases
- Refusing Medical Treatment
- Suicide
When will a victim break the causal chain due to their ‘fright and flight’ ?
If the escape/response of the victim was reasonably forseeable, the chain will not be broken.
If the response is not reasonably forseeable, there will be no legal causation.
When asking what is forseeable, the jury take the knowledge the defendant had at the time of the act, and consider characteristics visible to a reasonable man.
For example, jumping out of a car where the driver was making unwanted sexcual advances did not break the chain and D was convicted of ABH
When will a victim refusing medical treatment, resulting in their death, break the chain of causation?
Very unlikely to be a novus actus interveniens. Following cases….
- JW refused to have a blood transfusion on religious grounds and died - D convicted because you must take your victim as you find them including mind and body.
- A surgeon advised a victim to have a finger amputated. They refused and weeks later died of indection. The court held D was still responsible ebcause it doesn’t matter whether the wound is instantly mortal or becomes a cause following refusal of treatment
Will a victims suicide break the chain of causation?
Suicide will not break the chain of causation if
- Ds unlawful act was a significant and operating cause of death; AND
- At the time of the attack, it was reasonably forseeable that the victim would bie by suicide as a result of the injuries
Applying this, it may break the chain if…
- The injuries inflicted by D have healed but the victim commits suicide anyway
- It was a voluntary, informed decision of the victim
What is the thin skull rule?
A person inflicting harm cannot escape liability if the victim, owing to some pre-existing infirmity, suffers greater harm that would ahve been expected
You take the victim as you find them
For example, you cannot escape liability because someone dies from a heart abnormality simply because you didn’t expect them to suffer from such a condition
When will a natural event break the chain of causation?
Onyl if the event is extraordinary and not reasonably forseeable
For example, if you knock V unconscious and leave her on a beach, the fact a tide comes in and drowns her is reasonably forseeable. However, if you were in the UK and knocked someone unconscious, and a once in a lifetime hurricane kills her, that could be an intervening event.
What is the general rule about omissions?
A defendant cannot be criminally liable for a failure to act as there is no general duty to prevent harm
What are the 6 circumstances whereby failure to act may give rise to criminal liability?
- Statutory Duty
- Special Relationship
- Voluntary Assumption
- Contractual Duty
- Creating Dangerous Situation
- Public Office
When will a special relationship allow for criminal liability for an omission?
Relationships such as….
* Doctors and Patients
* Parents and Children
* Spouses
…. In Hood D (husband) failed to summon medical help for his wife who fell. Liability arose from their marriage.
What is the consequence of a person voluntarily assuming a duty towards another and then failing to act?
The law helds a person who voluntarily assumes a duty liable if they fail to carry it out.
For example, if you undertake to care for an ailing relative, a duty arises. If they die due to neglect, the omission can give rise to liability (e.g. manslaughter)
An employee is tasked with operating the train level crossing gates. He fails to do so, causing a crash and killing 10 people
How is he liable for the omission?
A duty can be owed via a contractual duty (e.g. the employment contract)
When will the creation of a dangerous situation give rise to criminal liability in the context of omissions?
If D creates a dangerous situation (e.g. starting a fire) they have to take reasonable steps to counteract the danger (e.g. extinguish the fire)
The steps need to be reasonable - they need not risk their own life but ought to summon help, warn occupants of the house etc….
If someone inadvertently sets into motion a chain of dangerous events, and beocme aware of what is happening, omission to prevent further damage and danger can become a criminal offence
What is direct intent?
The consequence is what D aims to happen - it is the purpose and objective.
This is a subjective test - what did D aim to do? Does D want to achieve injury?
