9. The appellant did not seek to challenge these assertions.
10. As a result, in our view, no challenge could be made to his Honour's finding that the insurer had been deliberately deceived by the appellant so as to exaggerate his claim.
11. His Honour found, on the evidence of Mr Nunn, an NRMA officer who had carriage of the appellant's claims, that the latter had recommended settlement of the appellant's claim based on the reports submitted as a result of the appellant's deception. His evidence was challenged on the basis that, in considering the pre-settlement material, he knew, or ought to have known, that the appellant had been exaggerating his disabilities.
12. That submission did not find favour with his Honour. He viewed the pre-settlement video material referred to and, whilst agreeing that it could have indicated exaggeration, found that it was not sufficiently unequivocal to have warranted a dismissal of the evidence supporting the appellant's claims, relying as they did primarily on psychiatric disability. It was clearly open to his Honour so to conclude.
13. Even assuming Mr Nunn had been less than diligent, his Honour was of the view that Toubia v Schwenke (supra) precluded reliance by a fraudster on the lack of diligence of the victim in detecting the fraud.
14. Nor, in his Honour's view, did the fact that the settlement could be regarded as a compromise, or that the insurer may have entertained some suspicion of exaggeration in proposing such a compromise, preclude relief under s 66.
15. The next submission was that the onus lay on the respondent to establish the extent to which the settlement had been caused by the fraudulent misrepresentations. In the absence of such evidence, it was contended for the appellant there was no demonstrated causal connection between the quantum of the settlement and the fraudulent statements.
16. The contrary proposition, as his Honour accepted, might lead to a claimant being obliged to confess his deception and then, burdened by his demonstrated lack of credibility, give evidence of the "true" level of his disabilities, if otherwise the evidence seemed to undervalue them.
17. His Honour accepted that an assessment of the extent of the overpayment had to be made and that he was required to be satisfied as to the quantum of it, but considered that this could be done on such material, including any evidence presented by the former plaintiff, as the Court had before it.
18. The effect of Mr Nunn's evidence was that, had he known the truth of the matter, he would have offered no more than $10,000. However, his Honour did not regard himself as bound to apply that approach. He examined for himself the circumstances of the accident and the medical evidence that related to its sequelae. That indicated to his Honour, as a matter of fact, that there had been "soft tissue injuries of some significance". As a result his Honour felt able to conclude that the appellant - [76]
