Tort Law - Causation Flashcards
What does factual causation deal with and what is the starting point? (4)
It deals with establishing the link between the defendant’s breach and the claimant’s damage. The starting point is always the ‘but for’ test, which means but for the defendant’s breach of duty, would the claimant have suffered their loss at that time and in that way. This is on the balance of probabilities.
If the answer to the but for test is no? (1)
Factual causation is satisfied, the claimant would not have suffered their loss were it not for the defendant’s breach.
If the answer to the but for test is yes? (1)
Factual causation is not satisfied and the defendant is not liable. The claimant would have suffered their loss even without the defendant’s breach.
Key case for but for test and factual causation? (1)
Barnett V Chelsea and Kensington Hospital 1969.
Key case for factual causation / but for test failing? (1)
Wilsher V Essex Aha 1988.

Chester V Afshar 2004.
Key case where but for test is accepted? (1)
Hoston V East Berkshire Health Authority 1987.
What may happen when there is more than one potential cause of the damage which operated together to cause the claimant’s loss? (1)
The courts might depart from the ‘but for’ test and apply the material contribution test.
What cases do the courts commonly depart from the ‘but for’ test and apply the material increase in risk test? (1)
In industrial disease single agency cases such as mesothelioma and lung cancer caused by asbestos.
When may loss of chance be argued? (1)
Where the loss is pure economic loss.
Key case of when material contribution test is satisfied? (2)
Bonnington Castings V Wardlaw and Bailey V Ministry of Defence.
Key case of when increase in risk test is satified? (1)
Mcghee V National Coal Board.
Key case where loss of chances not satisfied? (1)
Hotson V East Berkshire Health Authority.
Key case where loss of chance satisfied? (1)
Allied Maples Group V Simmons & Simmons
What is apportionement? (2)
A calculation to apply once factual causation has been established. Where multiple tortious factors have caused the loss, the courts apportion liability between the defendants to produce a practical result, providing compensation to the claimant while recognising the respective fault of the defendants.
