Underlying Principles Of Criminal Liability Flashcards
What is Actus Reus?
The physical element of the crime.
What is Actus Reus made up of?
All the elements of the offence except D’s state of mind.

‘Guilty Act’
In terms of Actus Reus, D’s conduct must be what?
Voluntary.
What is an omission?
A failure to act.

What do result crimes require?
D’s conduct to produce a particular result.

What do action crimes require?
The defendant to do a specified act. Once the act is done, the Actus Reus is complete. It does not matter what the consequences are:
E.g. Perjury- D lies under oath. It will not matter if the courts believed him or not.
Explanation of contractural responsibility + case?
If a defendant is under a contractural duty to act and fails to do so, they may be liable if others are likely to be injured as a result.
R v Pittwood : gate keeper forgot to shut gate. D was liable because it was his job to do so.
Explanation of parental responsibility + case?
Parents owe a duty to their children.
R v Gibbons & Proctor : D’s liable when they failed to feed one of the children and she died.
Explanation of voluntary acceptance of responsibility + case?
A duty to act may also be imposed where someone voluntarily accepts responsibility for another.
R v Stone & Dobinson : D’s liable when she refused to take care of person she volunteered to help.
Explanation of public duty + case?
Those holding a public office may be held liable for their omissions.
R v Dytham : D’s liable when he failed to fulfil his duty when he observed a fight that killed a man
Explanation of creating a dangerous situation + case?
The creator of a risk to another’s life or property is under a duty to act in order to stop or at least limit the harm caused
R v Miller : D’s liable for arsen when he accidentally started a fire and moved to another room and didn’t extinguish it.
Explanation of statutory omissions + case?
Duties can also arise through statute.
Road traffic act 1988: makes the failure to wear a seatbelt an offence.
Causation is only an issue in what crimes?
Result crimes such as ABH, GBH and murder.
What must the prosecution prove with causation?
They must prove, beyond reasonable doubt, that the defendant caused the prohibited result.
E.g. For ABH, they must show that the defendants actions caused the actual bodily harm.
How do the prosecution prove causation?
They must show that the defendant was the factual and legal cause of the result.
How do you test for factual causation?
The ‘but for’ test - would the result have happened ‘but for’ the defendants actions.
In what case was the but for test established?
R v white - D intended to poison his mother, who died from an unrelated heart attack
Legal principle of R v white?
But for D’s actions, would his mother have died? The answer is yes she would have died anyway. D was therefore not the factual cause of his mothers death. D was guilty of attempted murder.
What is the de minimis rule?
D’s actions must make a more than minimal contribution to the result.
Why do we need legal causation?
Legal causation is required to ensure that only the truly blameworthy are criminally liable. The link between the act and the consequence is known as the ‘chain of causation’.
The test for legal causation?
The test is whether D’s actions were the substantial and operating cause of the result.
What is the substantial cause? (+ case example and legal principle)
D’s actions must be a significant cause of the death
E.g. R v Pagett : police bullet killed his girlfriend after he used her as a human shield.
Legal principle : D’s acts do not have to be the sole cause or even the main cause of death, provided that they contributed significantly to the result.
