Ground 1 - Damages for Commercial Domestic Assistance
14 The appellant contended that the award made by the primary judge under this head was unwarranted as there was no evidence that as a result of the injury suffered by the respondent in the 2004 accident, or indeed for any reason, he required, or would require, commercial domestic assistance.
15 The evidence indicated that such domestic assistance as the respondent needed was being provided at the date of trial by his wife, and to a limited extent by his adult son who lived with him. The appellant pointed out, correctly, that there was no evidence that this gratuitous assistance would cease at some time in the future.
16 In our view, the award made by his Honour cannot be justified. It was made upon the assumption that the respondent required commercial domestic assistance immediately and would continue to do so for the rest of his life. However, it is clear that he did not require it immediately because it was being provided gratuitously, though to the extent that it could be attributed to the accident, not at a level of intensity that permitted recovery from the appellant.
17 As the assessment made by the primary judge cannot be justified, it is necessary for this Court to make an assessment.
18 There is no reason in principle why, if the evidence justifies it, damages may not be awarded in respect of a need for commercial domestic assistance likely to arise in the future after the availability of gratuitous assistance ceases. Such an award of damages was, for example, made in Nominal Defendant v Lane [2004] NSWCA 405. Giles JA (with whom Ipp and Tobias JJA agreed) said in that case:
"75 …. It was for his Honour to find what was likely to occur after the respondent's mother reached 65. He was evidently not satisfied that the respondent would be cared for, in an appropriate manner, by some combination of other family members and the townsfolk; hence he made allowance for professional care. It was well open to his Honour to take that view. The judge was looking ten years and more ahead. The respondent's sister and brother, and no doubt the cousins, had their own lives, and with due regard to familial and cultural responsibilities in my view it was open to the judge to think it unrealistic to assess damages on the basis that, when the respondent's mother was unable properly to do so, the respondent would receive the requisite care from other family members. Nor could the townsfolk be expected to contribute in any significant way to the requisite care".
19 The evidence accepted by the primary judge at the additional domestic assistance required as a result of the accident, assessed at four hours per week, was, since the accident and at the time of trial, being provided by the respondent's wife, with limited assistance from his son. Whether that assistance would continue to be provided by them on a gratuitous basis was a factor which the primary judge was entitled to take into account. If that circumstance were to change in the future, domestic assistance would, foreseeably, be required from a commercial provider. However, that expense was neither immediate nor inevitable. No doubt the likelihood of the contingency would increase with time, but other factors would have a contrary tendency.
20 There are four relevant variables, three of which relate to the condition of the respondent and the fourth to the circumstances of the carers. First, the calculation undertaken by the primary judge assumed a life expectancy of 24 years (the respondent was 61 years of age at the time of the trial). The respondent's medical history, as set out in the judgment of the primary judge, demonstrated a significant possibility that he would not survive until the age of 85 years. Any amount awarded must be discounted accordingly. Secondly, the greater proportion of his disabilities resulted from his pre-existing condition and not from the accident. Having suffered a stroke and two heart attacks, there was a significant possibility that further ill health would overwhelm the needs created by the accident. Thirdly, though perhaps less significant in this case than in others, due to the respondent's state of health, age alone is likely to create a similar need for domestic assistance, in later years, to that created by the accident.
21 The fourth factor concerns the ability and willingness of family members to provide assistance. The primary carer was the respondent's wife. At the date of trial, she was 51 years of age. She was sufficiently fit and healthy to be providing the assistance he required at that time and, indeed, was in receipt of a carer's pension for that purpose. Undoubtedly age will weary her, but, apart from the usual contingencies, there was no reason to suppose that she would not continue to be able and willing to assist him for many years to come. Similarly, there was no evidence of likely inability on the part of the son, although he might relocate to an area too distant from his parents' home to permit him to provide regular assistance. However, his assistance was largely with lawn mowing and constituted a small part of the domestic assistance required. The likelihood that he would not be in a position to visit his parents on a sufficiently frequent basis to help in that regard was a contingency which should be taken into account, but was far from a certainty, both as to the event and its timing.
22 In Malec v JC Hutton Pty Ltd [1990] HCA 20; (1990) 169 CLR 638 at 643, Deane, Gaudron and McHugh JJ accepted that future events "may be predicted and the hypothetical may be conjectured" and required that the Court take its assessment of chance into account unless a particular chance was "so low as to be regarded as speculative - say less than 1 per cent". However, in most cases prediction and conjecture do not in practical terms allow for such precision. As explained by Brennan and Dawson JJ at 640, damages founded on "hypothetical evaluations defy precise calculation". In most cases, the exercise is better described as a form of speculation guided by knowledge of the plaintiff's past and expectations, derived from general experience, as to the future.
23 In Malec, the question was whether the damages caused by the accident would have occurred in any event. In the present case, the question is whether the damage which has occurred will result in a compensable loss at some future time, taking into account the contingencies referred to above. The possibility of such a loss is perhaps not entirely fanciful, but the chance of it occurring is slight.
24 In awarding damages for loss of earning capacity, allowance is routinely made for contingencies or vicissitudes which may, absent the tortious injury, have caused loss in any event. Conventionally, a figure of 15% is allowed for such contingencies: see State of New South Wales v Moss [2000] NSWCA 133; (2000) 54 NSWLR 536 at [31]-[33] (Mason P) and the authorities referred to, including Wynn v NSW Insurance Ministerial Corporation [1995] HCA 53; (1995) 184 CLR 485 at 497-498 (Dawson, Toohey, Gaudron and Gummow JJ). There is no conventional allowance for the provision of domestic assistance on a commercial basis at some future point in time, against the possibility that the gratuitous carer may no longer be able or willing to provide such care. If any such convention were to be adopted, it would, as with vicissitudes, require the plaintiff's particular circumstances to be taken into account. The respondent's circumstances in this case militate against any such allowance. Accordingly, it is not appropriate in this case to simply pluck a figure out of the air because there is a remote, though not entirely fanciful, chance of the need for commercial domestic assistance in the future."
25 The appellant contended that an award under this head was not permissible because the respondent's case at trial did not include a claim for commercial domestic assistance. We do not accept this submission. The respondent's particulars of his claim expressly sought an award at commercial rates for the period after gratuitous care had ceased to be available to the respondent. Further, an agreement was made between the parties, and announced to his Honour, as to the hourly cost of commercial domestic assistance. The judge was informed of this agreement upon the second, and final, day of the trial. The announcement by counsel for the respondent of the agreement clearly indicated that the claim made in the particulars was still on foot.
