"84 As the claim form was received by the Nominal Defendant on 22 July 2002, and the Nominal Defendant had neither admitted nor denied liability within three months, it was deemed, under section 81(3), to have denied liability as from 23 October 2002. AAMI's letter of 3 June 2003 was the type of admission of liability, after an initial denial that is permitted by section 81(4).
85 The admission made by AAMI's letter of 3 June 2003 was of breach of duty of care. As the claim made by the plaintiff was that the driver of the unidentified vehicle had committed the tort of negligence, and as someone is liable for the tort of negligence only if that person owes a duty of care to the plaintiff, has breached that duty of care, and the plaintiff has thereby suffered damage, the admission made by AAMI was not, strictly, an admission of liability for the claim. The admission of breach of duty of care necessarily contained within it an admission of the existence of a duty of care, but no admission was made of any consequential suffering of damage. Thus it counts as an admission of liability for only part of the claim. An admission of liability for part of a claim, in this way, can fairly be described as a notice that includes "details sufficient to ascertain the extent to which liability is admitted" , and thus is expressly contemplated by section 81(2) MAC Act .
86 I recognise that the letter also indicates an intention to pay medical accounts in full. Section 83 imposes an obligation on an insurer to make such payments even if there has been a partial admission of liability, so it does not seem to me that the offer to pay medical accounts is an admission that there has been any consequential damage. It would still be open to AAMI to dispute whether any particular medical account related to the injury caused by the fault of the driver of the unidentified vehicle, or indeed, if there was a factual basis for doing so, whether there were any such medical accounts."
69 By contrast, the notice issued by the plaintiff in the present case did not address the issue of contributory negligence at all. This, so it was submitted by the plaintiff, together with the fact that there was nothing in its letter to justify the inference that it was making a partial admission of liability, rendered the notice inadequate for the purpose of the assessor ascertaining the extent to which liability is admitted as required by s 81(2), and that it is invalid as a notice for that reason.
70 Although, as Campbell JA observed in [85] above, the insurer's stated intention to pay for all reasonable medical expenses is not an admission that there has been damage suffered consequent upon breach, s 81 only imposes an obligation to meet such expenses where the insurer admits liability. Here the insurer clamed in its letter of 29 April 2005 that it had looked at the circumstances surrounding the accident and on that basis accepted that the insured driver was at fault and agreed to pay the third defendant's reasonable medical expenses. The fact that, the letter omitted to address the extent to which the third defendant should bear some responsibility for the accident, whether by error or oversight, in my view, does not diminish the force of its admission of liability, an admission which is open to be read in an unqualified way. Equally, the fact that in the absence of some specification of the extent of contributory negligence there may be insufficient details to ascertain the actual extent to which liability is admitted does not render the notice ineffective, even if the notice might be deficient from the insurer's perspective.
71 I am not satisfied that the PCA was in error in finding the notice was adequate to operate as an admission of partial liability under s 81(2).
