(d) by reason of the Applicant's pre-existing condition exposure to the fumes from time to time resulted in an aggravation, acceleration or exacerbation of the Applicant's pre-existing condition by reason of the Applicant's unusual susceptibility and that aggravation, acceleration or exacerbation of the Applicant's pre-existing condition is a compensable "injury" within the meaning of the Worker's Compensation Act 1987 (NSW)"
48 It is clear that QBE defended the proceedings in the Compensation Court on the basis that Ms Chew did not suffer an injury as a result of toxic fumes entering the cabin. Rather it endeavoured to prove that the fumes to which Ms Chew was exposed would have resulted in no more than minor and transient irritation to a normal person but were injurious to Ms Chew because of her pre-existing viral condition. To this end it called a number of expert witnesses including Dr Crank, a chemist.
49 Dr Crank gave evidence that, although Mobile Jet Oil 2 contains TOCP, a toxic substance, the percentage of TOCP in the jet oil was as low as 0.03 per cent. He also stated that, given that the make up of air in the cabin was 60 per cent pure and 40 per cent recirculated air, there was no toxicity in the air to which Ms Chew was exposed. Judge Moran accepted the evidence of Dr Crank and made findings accordingly.
50 His Honour also accepted evidence of two doctors who were part of a panel of medical experts and were called by QBE as to the risk of injury arising from the fumes in the cabin. His Honour quoted from their evidence the effect of which was that, given the low level of contaminants, the air in the cabin was not a threat to the health of aircrew or passengers. Judge Moran also preferred evidence given by medical experts called by QBE that denied the validity of the diagnosis of multiple chemical sensitivity.
51 The result of his findings was that Judge Moran rejected the worker's primary claim that she had suffered a specific injury as a direct cause of her inhalation of toxic fumes in the cabin. Rather his Honour found that Ms Chew was suffering from a pre-existing, aggravated form of a viral infection and this made her susceptible to exposure to fumes that otherwise were harmless.
52 In the light of the evidence led by QBE and the findings made by Judge Moran, BAE argues that QBE ought not be allowed to proceed with a statement of claim that alleges, in paragraph 6, that Ms Chew was injured by inhaling fumes that contained TOCP. BAE argues that it is an abuse of process for QBE to seek to prove against BAE the very fact that it sought to deny before the Compensation Court. It is argued that it would bring the courts in this State into disrepute to permit a party to seek and obtain contradictory findings in different proceedings in which it is involved.
53 Alternatively BAE argues that there is insufficient prospect of QBE succeeding on the allegation in the statement of claim in light of the evidence that it relied upon in the proceedings in the Compensation Court to warrant it being put to the trouble and expense of defending the action. BAE accepts that the Court would not normally interfere in proceedings of this nature unless there is a high degree of certainty about the outcome of the proceedings if they were allowed to proceed: Agar v Hyde at [57]-[60]. But it argues that, in the light of the evidence QBE called before Judge Moran, there is no prospect of it proving that BAE breached a duty of care it owed to Ms Chew.
54 QBE argues that it is not bound by the findings of Judge Moran particularly given the nature of the proceedings in the Compensation Court. It stressed that the proceedings in that Court were concerned, not with finding fault on the part of BAE, but with determining whether the worker suffered an injury in the course of her employment. It argues that the Court cannot glean sufficient information from the judgment of Judge Moran to form any view about how those representing QBE decided to defend the action or the manner in which they did so. It submitted that Judge Moran found that the worker was injured from fumes in the aircraft cabin and, therefore, prima facie QBE is entitled to seek indemnification from the company that allowed fumes to enter the cabin.
55 It should be noted that the essence of the proceedings brought by QBE is to obtain an indemnity from BAE for the compensation paid by it to Ms Chew. That indemnity must, it seems to me, be seen in terms of the findings made by the Compensation Court in determining that compensation be paid. As I have pointed out, QBE sought to defend those proceedings, not on the basis that Ms Chew suffered no compensable injury, but rather that she did not suffer an injury directly as a result of the inhalation of toxic fumes containing TOCP. Presumably QBE had an interest in defending the proceedings to the extent of calling a significant case based upon expert evidence to deny the worker's claim based upon this ground. It was successful in achieving that result. The compensation payments, therefore, were made, not on the basis that the worker inhaled noxious fumes that contained TOCP, but rather that, because of some pre-existing disorder, the worker was injured by the inhalation of fumes not otherwise injurious to the health of those present in the cabin.
56 There is no particular allegation in the Statement of Claim inconsistent with the findings made by Judge Moran in accordance with the evidence called by QBE. For example, there is no claim that the fumes in the cabin were toxic. I presume that there was some substance in the fumes, such as TOCP, to which the worker was highly sensitive and which caused her injury and so paragraph 6 of the statement of claim would be consistent with the evidence before the Compensation Court. I am prepared to act on the basis that fumes entered the cabin because of some design or manufacture fault with the aircraft.
57 I accept that generally a court would not be entitled to strike out a Statement of Claim simply because there may be a perceived difficulty in proving one or more allegations made in it, even if there be material before the court upon which an assessment could be made of the strength of the evidence to be relied upon by the plaintiff. But the present case seems to me to be a highly unusual one by reason of the earlier proceedings in the Compensation Court and the stance taken by the plaintiff in those proceedings. Further, the nature of the present proceedings, being for an indemnity, seems to me to invite some consideration of the basis upon which the compensation order was made upon which BAE relies. I accept that no estoppels arise in the present case because the proceedings before the Compensation Court did not involve BAE. I also appreciate that the very nature of the proceedings in that Court were not concerned with finding fault on the part of any person or corporation let alone assigning fault to any particular entity.
58 But it seems to me to be wrong, in a general sense, for QBE to seek to obtain an indemnity from BAE on the basis that BAE breached its duty of care to the plaintiff in a way apparently inconsistent with how the proceedings were conducted in the Compensation Court. Clearly QBE defended the claim made by Ms Chew on the basis that the fumes that entered the cabin were not only non-toxic but were not a threat to the health of any of the persons in the cabin, be they airline staff or passengers. The evidence from BAE's medical experts was that:
