General Elements of Liability and the Elements of a Crime: Causation Flashcards
In order to establish causation, what three things are required of the defendant’s conduct?
It must be:
- The factual cause of the consequence
- The legal cause of the consequence
- There must be no intervening act which breaks the chain of causation
What are the two tests for proving factual causation?
- the ‘but for’ test
- the de minimis rule
What case established the ‘but for’ test?
- White (1910)
What happened in Dalloway (1847)?
- Defendant held not liable for running a child over with his cart as he would not have been able to stop the cart in time, even if he had been holding the reins
What was the ruling in Paggett (1983)?
- Man convicted of manslaughter as the use of his 16 year old pregnant girlfriend as a human shield is what killed her (shot by police)
What is the de minimis rule?
- The defendant’s actions must be more than just a minimal cause of the death but need not be substantial
Name a case that illustrates the de minimis rule. How else was the rule referred to in this case?
- Kimsey (1996)
- There needs to be “more than a slight or trifling link”
Legal causation can be proved by any of which three requirements?
- that the original act was an operative and substantial cause of the consequence
- that the intervening act was reasonably foreseeable
- the thin skull test
Name two cases that illustrate the fact that medical treatment rarely breaks the chain of causation
- Smith (1959)
- Cheshire (1993)
Name a case where medical treatment was seen to have broken the chain of causation. What happened?
- Jordan (1956)
- Original wounds were nearly healed and the victim was given ‘palpably wrong’ treatment, so the defendant was not liable
What is the key difference between Cheshire (1993) and Smith (1959), and Jordan (1956)
- In the first two the doctors were trying to save the victims’ lives. In Jordan, the injuries had virtually healed
Which case showed that switching off a life support machine will not break the chain of causation?
- Malcherek (1981)
What is the Latin term for an intervening act?
- Novus Actus Interveniens
What can intervening acts be? (3)
- An act of a third party
- The victim’s own act
- A natural and unpredictable event
What was decided in Pagett (1983) in terms of foreseeability?
- the action of police returning fire was foreseeable (the whole pregnant 16 year old human shield thing)
