Q

McGhee v National Coal Board outcome

A
  • D had breached the duty it owed to C by failing to provide adequate washing facilities
  • current state of medical knowledge could not say whether it was probable that C would not have contracted dermatitis if he had been able to take a shower after work (there was an evidential gap- no science to prove otherwise)
  • C could not establish ‘but-for’ (factual) causation

Q

what did Lord Wilberforce say about D’s in McGhee (3)

A
  • the creator of the risk should suffer from evidential difficulty
  • D’s usually have deep pockets
  • loss spreding may seem desirable to reduce impact of losses on individuals

(A lot of sympathy for C but causation issue isn’t solved)

Q

what did the McGhee doctrine establish with regards to proof of causation

A

established how to deal with the problem of an evidential gap

32
Q

Clark v MacLennan what happened (3)

A

(i) D departs from a general practice and
(ii) the harm that the practice was supposed to forestall occurs,
(iii) D bears the burden of proof on breach of duty and causation.

(McGhee could be applied to a medical context)

33
Q

Fitzgerald v Lane outcome

A
  • McGhee doctrine stretched

- Burden of proof on causation borne by D

34
Q

Wilsher v Essex Area Health Authority outcome

A
  • D added to the list of factors which could lead to injury

- courts accepted that McGhee should apply

35
Q

Wilsher v Essex Area Health Authority- what does BW say about this case and McGhee

A

that they are ‘wholly different’- distinguishable (CoA)

36
Q

Wilsher v Essex Area Health Authority- HoL, and Lord Bridge

A
  • McGhee not applicable, it did not lay down a new principle
  • Lord Bridge: Causation must be proved on the balance of probabilities (his view is radically different from what lord Wilberforce intended very clearly in Wilsher).
37
Q

how did Fleming describe Lord Bridge’s comment on balance of probabilities (Wilsher case)

A

Fleming described Lord bridge’s commitment to proof on the balance of probabilities as his ‘unrelenting credo’

38
Q

Fairchild v Glenhaven Funeral Services Ltd outcome

A
  • Wilsher applied: causation not proved (CoA)

- HoL: McGhee applied

39
Q

why was McGhee applied by the HoL in Fairchild

A

Where D:

(i) breaches duty owed to C and brings about
(ii) a material increase in risk, liability can be imposed on D for
(iii) the full loss

(D may have been responsible for only a small proportion of the exposure to risk- fair? is this case fair for multiple wrongdoers?)

40
Q

Relevant considerations in Fairchild

Lord Nicholls

A

rejecting the claims would have been ‘deeply offensive to instinctive notions of justice’

41
Q

Relevant considerations in Fairchild

Lord Rodger

A

the empty duty argument. What’s the point of holding employers under a duty to take reasonable care, if you can’t bring actions against them when they fail to take reasonable care?

42
Q

Relevant considerations in Fairchild

Lord Bingham (2)

A
  • the balance of fairness argument. The balance of fairness lies with putting liability on the duty of breach.
  • The overall object of tort law is to define cases in which the law may justly hold one party liable to compensate another’. Pragmaticism?
43
Q

what was the overall argument made in Fairchild

A

the House of Lords made it clear that, in most cases, C must prove causation on the balance of probabilities.

44
Q

what was the overall argument made in McGhee

What did Lord Hope say

A

only has relevance in exceptional cases

-Lord Hope stated that Lord Bingham correctly interpreted it in Fairchild

45
Q

Barker v Corus

extent of liability is confined to …?

A

-The extent of liability is confined to the extent that D materially increased the risk to which C was exposed

46
Q

Barker v Corus

relevant concerns with regards to apportionment of damage (3)

A

(i) duration of exposure;
(ii) intensity of the exposure;
(iii) the type of asbestos.

47
Q

Barker v Corus

what considerations came about

A
  • policy arguments

- asbestos related claims became popular

48
Q

why did Lord Rodger dissent in Barker v Corus

A
  • there was a tussle on the meaning of justice

- here Lord Hoffman was trying to be just to Ds, in Fairchilds, C’s were given more thought about

49
Q

The Compensation Act 2006, section 3(1) (the ‘mesothelioma amendment’)

what does it state

A

-A ‘responsible person’ is liable for all relevant harm (even if C has been exposed to asbestos by others).

50
Q

why is there a return to Fairchild, after Barker

A

-Under Barker , C had to find and sue each careless employer in order to recover full compensation.

51
Q

pleural plaques- Rothwell case outcome

A
  • The plaques did not constitute actionable physical injury.
  • Risk of subsequent injury insufficient to ground a claim.
  • Psychiatric injury resulting from fear that disease may develop insufficient to ground a claim

(not actionable)

52
Q

Sienkiewicz v Greif (UK) Ltd outcome

A
  • A problem: all residents of Ellesmere Port had been exposed to low levels of asbestos in the general atmosphere
  • D liable for full loss (Fairchild/ s3(1) CA 2006)- D appealed to SC which was dismissed
53
Q

what does Lord Rodger say in the Sc in Sienkiewicz about Fairchild

A
  • ‘the Fairchild exception applies in single exposure cases’
  • The C was entitled to succeed if she proved that D’s breach of duty materially increased the risk that her mother would develop mesothelioma
54
Q

material increase in risk

what does Lord Phillips say ‘material’ is
-how do we establish whether a risk is de minimis

A

“material” is intended to exclude an increase in risk that is so insignificant that the court will properly regard it on the de minimis principle’

-Establishing whether risk exposure is de minimis: ‘This must be a question for the judge on the facts of the particular case’

55
Q

what does Lord Roger say in Sienkiewicz about a proper balance and the Fairchild exception

A
  • he wrote on ‘the proper balance’ between the parties’ interests in cases where the Fairchild exception applies
  • the Fairchild exception represents a ‘proper balance between the interests of claimants and defendants
56
Q

Williams v University of Birmingham first decisions

A
  • with the Fairchild exception, D found liable
  • there was a breach of duty and a resultant material increase in risk
  • D was under an obligation to take reasonable care to ensure that Williams was not exposed to a reasonably foreseeable and unacceptable risk of asbestos-related injury
57
Q

what does the principle of de minimis mean for liability

A

if quantity is de minimis (and not material), breach of duty cannot be established.- highlighted in Williams v University of Birmingham

58
Q

what did Aikens LJ say in Williams about establishing a breach of duty

A
  • : in order to establish breach of duty [and causation], a finding had to be made as to the actual level of asbestos fibre in the environment (where William had undergone exposure)
  • If the quantity was only de minimis (and not material), breach of duty could not be established.
59
Q

3 considerations adopted by Aikens LJ in Williams

A

1) what level of knowledge (in 1974) should the university have had about the risks posed by the relevant quantity of asbestos? What would the RP have made of the presence of asbestos in that context?
2) with this knowledge, should it have been reasonably foreseeable to the University that Williams was likely to be exposed to a risk of asbestos-related injury?
3) were there reasonable steps that the University ought to have taken in the light of reasonably foreseeable risk (which it had failed to take)?

60
Q

williams- final outcome

A

given the lack of knowledge in 1974 concerning the risks posed by small quantities of asbestos, harm to Williams had not been reasonably foreseeable

61
Q

Fleming on Traditionalism (3)

A

-proof on the balance of probabilities; direct, anecdotal, particularistic evidence; non-
statistical evidence.

  • Probabilistic evidence: relevant to non-traumatic injuries (e.g., injuries arising from exposure to toxic pollution).
  • Courts: typically uncomfortable with probabilistic evidence
62
Q

Fleming on innovation in the United States of America:

market share liability case

A

Sindell v Abbott Laboratories

63
Q

Sindell v Abbott Laboratories outcome

A

-Each of the 11 manufacturers should be held liable for that proportion of C’s injuries that corresponded to their share of the D.E.S. market (Market share liability)

64
Q

Fleming on innovation in the United States of America

Ayers v Jackson Township outcome

A
  • Cancerphobia was treated as a form of compensable mental injury. (cf cases concerning pleural plaques.)
  • Cf traditional refusal to compensate for increased susceptibility to disease
65
Q

Two dangers of a pro-claimant approach to proof of causation

case

A

Snell v Farrell

66
Q

Snell v Farrell outcome

A

there is a strong commitment to C’s and their interests, but if you relax the requirements of causation it could lead to medical malpractice for example

67
Q

psychology of causation

what does Atiyah identify

A

He identifies judges as exhibiting sympathy to claimants when determining causal questions.

68
Q

apportionment- what type was used in the following case

Rahman

A

apportionment tailored to the harmful wrongdoing of D1 and D2.

69
Q

apportionment- what type was used in the following case

Fairchild

A

70
Q

apportionment- what type was used in the following case
