Week 7- Causation, damage, remoteness Flashcards
Why is the ‘but for’ test for causation different regarding what must be established compared to the two exceptions?
What must be shown for the two exceptions to the law?
This is the only test for causation under which it is shown that the defendant’s negligence was a necessary condition of the claimant’s harm. They must show that the defendants negligence was more likely to cause the damage than any other factors. Once again it must be shown on a balance of probabilities.
The Wardlaw exception shows that the plaintiff must prove, on a balance of probabilities, that the defendants negligence materially contributed to the damage incurred by the plaintiff; it is applicable in both divisible and non-divisible injuries. it may not be a necessary condition because the injury may happen irrespective of the material contribution to harm.
The Fairchild exception, applicable only in a specific kind of indivisible injuries, requires that the plaintiff can prove that the defendants negligence was a material contributor to the RISK of harm, as opposed to a material contributor to the actual harm, as in Wardlaw. Owing to the inability to identify the extent to which one defendant materially contributed to the damage, based on the limited scientific knowledge surrounding mesothelioma and asbestos, which sets it apart from the Wardlaw exception.
Facts and significance of Bonnington Casting v Wardlaw 1956? (exception number one to “but for” causation?
Facts- A steel dresser exposed to silica dust at work, contracted pneumoconiosis. Part of the exposure derived from a failure on his employer’s part to discharge the duty under the Grinding of metals regulations 1925, as more precautions were expected to take place. The other contributing factor, a pneumatic hammer, could not have been made any safer through further precautions, so no duty of care was owed with respect to guarding against the risks associated with this.
Facts- Lords held that there was no need to show that the contribution of dust made by the swing grinders (which should have been guarded against) was more than 50% of the total exposure to the dust (to prove on a balance of probabilities that they caused the damage (but for)), with more dust coming from the ‘innocent’ hammer rather than the grinders. The employers were nevertheless liable for the disease.
- Ambiguous because it is not clear whether the Lords were ruling on the fact that the greater exposure added to the harm suffered (makes ‘material contribution’ compatible with but for test, as condition would not have been worsened but for the failure to guard against swing grinders.). Or it could rule on the basis that it exerted a causal influence, regardless of whether it would have happened without the swing grinder contribution, which clearly wouldn’t be compatible with ‘but for’ test.
- Nowadays, it’s likely that damages would be apportioned between the tortious and innocent causes of the disease.
- “One reading of Bonnington says that material contribution to injury could be shown in the sense that any exposure will have worsened the injury; it was a progressive disease. On a different reading, it was the interaction of different sources of dust which was taken to have caused injury; it was a case of material contribution to causation of damage.” Whilst not being the sole cause of damage, it made a material contribution, even if it didn’t reach a 50% threshold of contribution. The second reading of this is supported by the SC in Sienkiewicz.
- This is still proved on a balance of probabilities, not that it had to be proved to be above the 50% threshold of causative contribution, but that it was more likely than not to have made a material contribution to damage.
Barnett V Chelsea hospital 1969 facts and significance?
How can this causation case be explained in terms of consequences (damage) ?
Facts- The three men had been vomiting for 3 hours when they arrived at the hospital, after drinking tea. The nurse reported their complaints by telephone to the duty medical officer, who instructed her to tell the men to go home to bed and call in their own doctors. This, reportedly, is what the duty medical officer said:
“Well, I am vomiting myself and I have not been drinking. Tell them to go home and go to bed and call in their own doctors, except Whittal, who should stay because he is due for an X-ray later this morning” [at 431].
All of the men left. About five hours later, one of them died from poisoning by arsenic, which had been introduced into the tea. Nield J concluded that he would have died from the poisoning even if he had been admitted to the hospital and treated with all due care five hours earlier- intervening factors can break the chain of causation, or pre-existing factors which cannot be prevented, regardless of the any attempts made to cure etc.
Significance- There was a breach of duty of care in that the hospital failed to diagnose and offer care, but the ‘but for requirement’ clearly was not satisfied. Even if they employed the utmost care for the men, the man would still have died. The hospital had breached their duty of care, but not caused the death of the deceased, and therefore were not liable for the death in negligence. A breach of duty alone cannot constitute liability in negligence if it does not cause the damage to the plaintiff.
“Causation is, again, related to responsibility. The only ‘responsibility’ in question is responsibility for consequences. If no consequences flow from the breach of duty, then I am not responsible in tort for that breach. If there is an injury, but I could not have prevented that injury through proper conduct, then again, I am not responsible, even if my behaviour is culpable. Even a clear breach of a statutory duty will give rise to no liability in tort if it is not shown to have caused the eventual damage.”
What is ‘but for’ causation?
“In summary, the idea of ‘but for causation’ is treated by Hart and Honoré as no more than a useful way of asking whether the defendant’s breach of duty was effective in the history of events which led to the claimant’s loss, while avoiding ‘abstract metaphysics’. ‘But for’ causation is an important element in our common understanding of the nature of ‘cause’, particularly when causal questions are asked for the purposes of attribution of responsibility. ‘But for’ causation will, however, not always provide the tools that we need.”
But for causation:
-Not enough that the defendants action caused damage to the claimant’s property, it must have been done in a manner which breaches the duty of care and caused that relevant damage. But for is merely a starting point, which asks whether or not the damage would have happened but for the actions of the claimant. If it happens regardless, then it is not a necessary cause of damage. It must be established on the balance of probabilities, but if, on a balance of probabilities, it would more likely have happened regardless of Ds actions than not, then but for causation is not satisfied. It therefore wouldn’t be A NECESSARY CONDITION of the damage.
Facts and significance of Baker v Willoughby 1970 AC 467 regarding concurrent and consecutive torts?
Baker v Willoughby 1970 AC 467:
Facts- P suffered injury to leg in road accident caused by D. Shortly before his action was heard, he was shot in the same leg in an armed robbery, causing the leg to be amputated.
Significance- First tortfeasor liable for the damages which he had caused (despite the intervention of the second event). If the second tortfeasor had been available to sue, he would have had to pay for the additional pain, suffering, loss of amenity and loss of earnings, on top of what D paid with regards to the damage which he caused himself. D remains liable for his causal devaluation to the life of P in full, despite the second event, including the loss of amenity and lower earning capacity, despite the fact that he lost the full leg soon afterwards, which clearly wasn’t attributable to him.
Jobling v associated daries 1982 facts and significance regarding concurrent torts?
How does it disapprove of Baker v Willoughby?
Facts- P suffered back injury at work due to tort of D. Later developed disease to which he had a predisposition.
Significance- HoL held that disease had to be taken into account when assessing the damages. The reward of lost earnings due to Ds actions must be limited by the fact that he would have lost earnings from the onset of the disease from a certain point onwards.
-Conflict with Baker v Willoughby, which was called “unrealistic” by Lord Edmund Davies, and “not acceptable” by Lord Keith. This would be because whether or not the first injury had been caused (the leg being injured in the traffic accident), the eventual amputation would have superseded any effects of the accident anyway, and therefore why should he be liable for the lower earning capacity and loss of amenity which would have stemmed from the amputation of the leg, whilst the armed robber would only pay the additional damages?
Facts and significance of Performance Cars v Abraham 1962?
Facts- the appellant had negligently hit the car of the claimant, who’s Rolls Royce had also been hit two weeks earlier. The car required a re-spray, and the claimant sought to recover £75 from the first party who hit the car. Whilst waiting for the first £75, the claimant sought to recover from the second party (the appellant).
Significance- court held that claimant was not entitled to recover the same damages twice; the appellant was absolved of all liability. It was unjust and illogical for the claimant to recover another £75 from the appellant who had not caused the re-spray to be required. There was no extra damage which had been caused, but if there had been, the appellant would have been liable for any further damage which he caused from his own collision.
How limited is the scope of the Fairchild exception?
Why is the ‘but for’ test not possible to apply in similar mesothelioma cases?
The Fairchild exception is only going to apply to indivisible injuries with similar characteristics to the facts of that case ie there is a lack of medical knowledge which allows us to determine whether mesothelioma is caused by a singular fibre or more than one. Therefore we can’t determine the threshold which must be reached before the onset of the disease starts, which is why the ‘but for’ test isn’t possible to apply here- cannot confidently say that the same injury would have been suffered but for the certain employers negligently exposing an employee to asbestos.
What are the facts of Fairchild v Glenhaven 2002?
Claimants exposed to asbestos dust by a number of employers in different periods of employment. All developed a fatal form of cancer, and it was common knowledge that this could be caused by anywhere between one and many asbestos fibres. Once it had been caused, it was not aggravated by further inhalation, but rather the risk of developing the cancer would increase by further exposure.
What are the necessary conditions of the Fairchild approach?
1) Uncertainty: must be impossible for current scientific knowledge to prove who the true cause was of the increased risk of disease. If it is possible, then the burden of proof remains on the claimants. Otherwise, impossibility favours the claimant against the defendant, who is more likely to be liable where they increase the risk but are not the sole or material cause of the risk.
2) Single Agents: The Fairchild/ McGhee approach not applicable to cases like Wilsher, where there is a variety of different risks which the plaintiff is exposed to. Has to be the same type of risk/ exposure to the same agent.
3) Innocent or self-imposed periods of exposure: But the remarks suggested that if there is a case where one former employer who exposed the claimant to asbestos dust can be shown to have been not negligent (for example because they took proper precautions, or because their exposure of the claimant took place before the date on which such exposure could be said to give rise to foreseeable harm), then the solution reached in Fairchild may not apply. It would be provable that that defendant was not negligent, and therefore liability would fall on another defendant, or none at all. This is because they had discharged their duty of care eg in a Barnett v Chelsea hospital case.
Facts and significance of Chester v Afshar and the difficulty of applying the ‘but for’ test? What were the reasons for the strong dissents against the decision?
Facts- Chester had been complaining of lower back pains and was told that surgery would rectify the pain. She was not informed of the 2% chance of the surgery going wrong and suffered a subsequent complication. It was contended whether there was a causal connection between the failure to warn the patient, and the subsequent damage.
Significance- The court held that, had she been informed of all the risks, she may have sought alternatives, and therefore the failure to warn was a necessary cause of her damage. There were two strong dissents made out.
-Lord Steyn ruled in favour of the claimant because he felt that a failure to award damages would make the role of the doctor somewhat redundant. The risk would not have changed had she been informed, but the doctor had violated her right to choose, and but for this failure to make her aware of the risks, it is conceded that she would have chosen other options, so harm could have been avoided.
Dissent 1) Lord Bingham argued that a failure to inform was not equivalent to causation of her injury from the surgery. It had to be proved that Chester would not have had the surgery at all had she been informed of the risk, in order to satisfy causation. He argued that the ‘but for’ test has not been satisfied at all, and therefore causation has not been made out. The injury would have been possible whenever and by whoever had performed the surgery, not merely by the Dr and his failure to warn her of the injury.
Dissent 2) Lord Bingham argues that even if he had warned her of the risk and she had eventually had the surgery anyway, the risk of injury was still present. The Dr had not caused the injury, even if he had breached his duty of care towards his patient by failing to act in their best interests. “In my opinion this argument is about as logical as saying that if one had been told, on entering a casino, that the odds on No 7 coming up at roulette were only 1 in 37, one would have gone away and come back next week or gone to a different casino. The question is whether one would have taken the opportunity to avoid or reduce the risk, not whether one would have changed the scenario in some irrelevant detail.”
Facts and significance of Holtby v Brigham and Cowan 2000?
Facts- Claimant exposed to asbestos dust for several years, working for the defendant for half that time, developing a form of cancer different to that in Fairchild, because additional exposure makes this particular type of cancer worse, rather than merely increasing the risk of its development.
Significance- Held that defendant only liable for the extent that he contributed to the resultant disability. They rejected an approach based on the length of the exposure, and reduced damages payable by 25%.
- It’s been argued that in a case like Bonnington, argued today, an apportionment would likely be made, between the tortious and non-tortious causes.
- The Fairchild exception could not apply here so the defendant was not liable in full (shows strictness of the Fairchild exception- this is because the extent of the damage was 1) made worse by future exposure and 2) this further exposure could be attributed to the defendant)
Facts and significance of Barker v Corus 2006 UKHL, how has it been reversed following the compensation act 2006 s3?
Facts- similar to Fairchild, claimants had contracted the same form of cancer through exposure to asbestos over many years. One plaintiff had both worked for the defendant, as well as being self-employed, thereby exposing himself to the risk in addition to his employer.
Significance- Problem 1) self-exposure: HL agreed with CA and held that a period of self-exposure did not defeat the Fairchild approach. Where there is a single agent risk, it is not necessary that all the exposures were tortious (in this case the employers one was, but self-exposure was not). The contributory negligence of the claimant is a mitigating factor for the claimants share of responsibility. The defendants liability is for the full damage suffered, a strange rule considering that they were liable for the full damage suffered by the claimant, with the increased risk of injury being construed as the full injury rather than the eventual disease, which was caused by both self-exposure and negligence on behalf of the employer.
-However,
-This decision has been reversed by the Compensation act 2006 s3, which provides a liable person (or their insurer) to recover a contribution from the financial services compensation scheme. Liability therefore apportioned because the plaintiff had also endured a period of self-exposure, which was a provable aggravating factor.
What did the Compensation act 2006 s3 actually do with regards to mesothelioma related claims?
After the decision in Barker there was a swift and fierce political backlash, with large numbers of workers, families, trade unions, and Members of Parliament calling for the reversal of the ruling. This was on the basis that it would undermine full compensation for working people and their families. Soon enough the Compensation Act 2006[3] was introduced, specifically to reverse the ruling. However the Act only applies to mesothelioma. What remains to be seen is whether the “proportionate liability” idea will crop up in other situations
-This is only relevant to the situation where solvent and insolvent companies are jointly liable. Only the solvent company can pay his proportion of the damages when the companies are jointly and severally liable. The compensation act 2006 makes the liable solvent company fully liable, and capable of picking up contributions to cover the costs of paying out on behalf of the insolvent companies.
What is the position currently regarding non-tortious exposure and the rule in Fairchild?
Even where non-tortious exposure eg self-exposure also materially contributed to the risk of mesothelioma, the Fairchild rule would still apply. This is illustrated by the dismissal of the appeal in Barker.
