The period across which interest is to be paid
22 The plaintiff seeks interest under section 57 of the Insurance Contracts Act 1986 (Cth), which relevantly provides:
Interest On Claims
(1) Where an insurer is liable to pay to a person an amount under a contract of insurance or under this Act in relation to a contract of insurance, the insurer is also liable to pay interest on the amount to that person in accordance with this section;
(2) The period in respect of interest that is payable is the period commencing on the day as from which it was unreasonable for the insurer to have withheld payment of the amount and ending on whichever is the earlier of the following days:
(a) the day on which payment is made …
23 While the defendant accepts that the plaintiff is entitled to interest under this section, there is dispute over the date from which "it was unreasonable for the insurer to have withheld payment".
24 The determination as to at what time it became 'unreasonable' for the defendant to withhold payment must be made having regard to the particular circumstances of the case. It is not relevant whether the insurer acted bona fide in denying the claim or when the judgment of the Court established the insurer's liability to pay. The award of interest must be calculated with reference to the period after which the Court concludes it would have been a reasonable time for completion of the insurer's investigation of the claim. This does not mean that the insurer is automatically liable to pay from the date on which benefits first accrued or the claim might have been lodged (cf: Sayseng v. Kellogs Superannuation (2007) 213 FLR 174 at [7]).
25 The plaintiff's counsel submits that the plaintiff's disability commenced on 2 November 1999, and that the insurance waiting period of 30 days would have been ample time for the insurer to conduct its investigations and establish that the plaintiff's claim was genuine. As such, the plaintiff claims interest from 3 December 1999.
26 The defendant claims that it was not until the service on the defendant of a report of Dr David Van Der Walt of 8 November 2001 that the defendant had access to any evidence of the plaintiff's entitlement to benefits. The defendant maintains that a period of three months represents a reasonable time for the defendant to investigate and accept the claim. As a result, the defendant asserts that interest should only be awarded from a date three months after the service of Van Der Walt's report [February 2002].
27 The difficulty with the defendant's contention is that the alleged absence of evidence of the plaintiff's entitlement to benefits prior to November 2001 entirely due to the defendant's wrong. There was no dispute as to the fact that, were it not for the defendant's wrongful assertion that the policy had lapsed, the plaintiff would have immediately lodged a claim in 1999. Had she done so, she would have been required to obtain certain medical evidence, and the defendant would have been entitled to have her examined.
28 There is a long line of authority to the effect that 'no man can take advantage of his own wrong' [Cf. Broom's Legal Maxims, 10th edition, Pakistan Law House, 1989 at 191 et seq., noting that this maxim, being "based on elementary principles, is fully recognised in Courts of law and equity, and indeed, admits of illustration from every branch of legal procedure"]. The defendant therefore cannot rely upon an absence of medical evidence in order to avoid paying interest prior to 2001, if the absence of such evidence is due entirely to their own fault in wrongfully denying the plaintiff's entitlement to submit a claim under the policy.
29 It is now accepted that the plaintiff was, in 1999, medically entitled to benefits. The defendant argued that, despite this, the plaintiff would have been unable to obtain medical evidence in 1999 to support her eligibility. The defendant attempted to show that the medical reports of the plaintiff's treating doctors produced in 1999 were equivocal and did not suggest that the plaintiff was necessarily permanently disabled. For example, the defendant relied upon the report of the plaintiff's rheumatologist, Dr David Bossingham, who stated that "(a)t the moment one would have to have an open mind as to what was going to happen in the future", and expressed a 'hope' the plaintiff's condition would improve.
30 As Mr Rayment submitted, this evidence suffers from a number of flaws, including:
i. The relevant question to be answered in 1999 under the policy was not whether the plaintiff was permanently disabled forever, but rather whether she was presently disabled from earning two thirds or more of her average weekly income [CB 21 at D17.7].
ii. The medical materials that existed in 1999 were not provided for the purposes of that question. They were treating doctors or doctors provided for other purposes.
iii. The medical materials do establish that the plaintiff's treating doctors were aware, in 1999, that the plaintiff was significantly unwell. The plaintiff's condition was not invisible, and her doctors were already aware, in 1999, of the symptoms which lead Dr Van de Walt in 2001 to declare that the plaintiff satisfied the fund's definition of "ill health or total or permanent disablement".
31 In these circumstances, the evidence fails to establish any reason why the plaintiff would have experienced difficulty in obtaining medical support for her entitlement in 1999. There is no evidence that the plaintiff's condition was hidden, or that it only became obvious at a later date. Consequently, it is irrelevant if, because of the defendant's actions in denying the plaintiff's eligibility to lodge a claim, the plaintiff failed to actually provide the necessary medical evidence at the time in question.
32 As a result, the finding is that the plaintiff is entitled to be paid interest for a period commencing on 3 December 1999, 30 days after 2 November 1999. Bearing in mind that neither side adduced evidence on this issue, the finding is that this represents a reasonable time subsequent to the commencement of the plaintiff's disability for the completion of the insurer's investigation of the claim.
