Economic loss
14 It is convenient immediately to set out his Honour's reasons -
"The main part of the claim is for loss of income. The plaintiff worked as a builder at the time of his accident. He says he has been unable to work since the accident, he has considerable support from the doctors who say he is unfit for work as a builder, he is unfit for heavy work, he is not suitable for a desk type job. Doctor Scougall says that he is unfit for work and virtually is unemployable. I am satisfied that he may be able from time to time to do some sort of light work but he is fifty years of age, to get that sort of work with his qualifications at that age would indeed be difficult, and I take that all into account. I take into account that he did have a pre-existing condition and that he was vulnerable.
The next difficult part of this case, as with every part of it, was what he actually earned. His income tax returns do not reveal any substantial income from his building business before the accident. Moneys were paid into a trust but even when you look at the trust at its highest point it did not reveal any substantial income. On the other hand there is evidence that he was a competent builder and a hard working builder. It has been submitted by senior counsel for the plaintiff that the way to approach it is to allow the wages which would be paid to a craftsman such as a carpenter and to multiply it by a certain percentage starting at one and a half times that and going up to, I think about, two or three times.
I am provided with various calculations and I am content that the way to assess the plaintiff is to take the average weekly earnings and multiply it by 1.5 and doing that for the past I allow $149,000. In the future I note such an allowance would total $338,000 but that has to be reduced on several bases, one that he would have always been vulnerable to loss of time from work and loss of income even without this accident, and secondly there is no guarantee he just would have continued earning that sort of money in the future and doing the best I can and taking all that into account I allow the plaintiff a future loss of income in the sum of $275,000."
15 The grounds for the challenge to these amounts in the notice of appeal were that his Honour had failed to disclose adequately or at all the reasoning upon which he found it appropriate to assess the respective economic losses by reference to average weekly earnings multiplied by 1.5; that he had failed to disclose any or any adequate process of reasoning by which he assessed the respective economic losses on that basis; and in the alternative that his assessments were excessive.
16 Again, at the hearing of the appeal the challenge was more confined. In the appellant's written submissions it was said first that there was "not a scintilla of evidence" underpinning the calculation of economic loss on the basis of a multiple of average weekly earnings, and secondly that "the judgment does not disclose the essential steps in the trial judge's reasoning process that led to his Honour's acceptance of the submission to adopt and apply a multiplier of average weekly earnings". In the appellant's oral submissions it was accepted that, in principle, the economic loss could have been assessed on the basis of average weekly earnings, even factored up average weekly earnings, but it was said that the evidence in this case did not permit that course because it could not be found that it would throw up "a fair assessment" of economic loss. If the evidence did not permit the basis his Honour adopted, of course, an inadequate reasoning process would not be surprising.
17 The respondent was called as the first witness. He gave evidence of his early employment as a machinist, of learning bricklaying and carpentry, of working in the building industry as an employee and sub-contractor, and of obtaining an appropriate licence and beginning to do jobs as a builder a few years before the accident. The building jobs were described. He also undertook some property development activity in those years. The building and development work was undertaken by the respondent's company, Dynpan Pty Ltd ("Dynpan"), which acted as the trustee of a family trust.
18 Income tax returns for the respondent and Dynpan were tendered. A report of Furzer Crestani Services ("the Furzer report") had been served on behalf of the respondent as an accountant's assessment of damages for economic loss. When the cross-examination of the respondent turned to that area there was discussion between counsel and his Honour in which each counsel foreshadowed how his Honour would be asked to approach the assessment.
19 Counsel for the respondent referred to the Furzer report. It took two "scenarios", and within each scenario three alternative assumptions of residual earning capacity. The first scenario took earnings as a successful builder. Counsel for the respondent observed that it might not find favour because it depended on the perhaps unlikely assumption that the respondent would always be successful as a builder. The second scenario took average weekly earnings of a carpenter, but it was said that, on the basis that the respondent had an earning capacity greater than simply as a tradesman, the average weekly earnings should be increased by one and a half or two times. Counsel for the respondent indicated that he would primarily be relying on this basis for assessment of economic loss.
20 Counsel for the appellant accepted that there was "undoubtedly some loss of capacity", but said that the respondent "was never close to" the factored up average weekly earnings and that he would be submitting that "the base figures that he had been earning for years before hand" were the beginning and the end of putting a figure on lost earning capacity.
21 In due course the Furzer report was tendered. Its author was not cross-examined.
22 For the purposes of the first scenario the historical taxable income of the respondent and net income of Dynpan were summarised, and there was a separate profit and loss statement for a property development current at the date of the accident (it lost money). The net income of Dynpan showed a marked upward trend for the years ended 30 June 1990 to 30 June 1993, with a marked reduction for the 1994 year because of an extraordinary expense for commission. This expense was not explained; but for it, the upward trend would have continued. As his Honour said, the amounts were not substantial, although they were not insignificant (Dynpan's net income for the 1990 year was $11,179, for the 1993 year $32,495, and for the 1994 year $172 after the commission of $249,779).
23 But the first scenario took a more sophisticated approach than averaging or projection of the results of the five years. A separate schedule of "taxable income of the trust" analysed according to the building jobs described by the respondent was prepared, showing total taxable income of $89,558.00 generated in the 16 month period before the accident. The income was increased by $44,428 after adjustment for extraordinary items. The resulting $133,986 over 16 months was used as the basis for calculations of past and future economic loss. The past economic loss was $264,196 and, depending upon the assumed residual earning capacity, the future economic loss ranged from $807,651.00 (no residual earning capacity) to $581,167.00 (residual earning capacity of $500 per week gross before tax). These calculations took 30 June 1998 as the division between past and future.
24 For the second scenario the Furzer report took the average weekly earnings of a carpenter, not factored up, and calculated past economic loss at $93,137 and future economic loss, on the same alternative assumptions of residual earning capacity, from $291,219 to $64,735. The date dividing past and future was again 30 June 1998.
25 The Furzer report did not include calculations for factored up average weekly earnings. In due course there was tendered a "mathematical upgrade" of the calculations, using 16 February 1999 as the date dividing past and future and factoring up the average weekly earnings by 1.5, 1.75, and 2.00. The figure for the second scenario past economic loss based on average weekly earnings factored up by 1.5 was $149,302, corresponding to the $93,137 earlier mentioned. The figure for second scenario future economic loss based on average weekly earnings factored up by 1.5 and assuming no residual earning capacity was $388,179, corresponding to the $291,219 earlier mentioned. These were obviously the source of the figures of $149,000 and $338,000 found in his Honour's reasons.
26 There was no evidence to the effect that, but for the accident, the respondent would have worked as a carpenter earning the average weekly earnings or the average weekly earnings factored up by 1.5. But that does not mean that the approach his Honour took was erroneous.
27 The respondent exercised his earning capacity through Dynpan, and the tax returns show that his income was diverted via the family trust to members of his family. While his income tax returns did not reveal a substantial personal income, plainly they did not reflect his earning capacity. The net income of Dynpan was also not substantial, but it showed (subject to the unexplained commission) the marked upward trend to which I have referred. An upward trend would not be unexpected, given that the respondent's income earning activity was maturing into building and development work on his own account. Although not specifically referred to by his Honour, in narrowing down the income earning activity to the 16 months prior to the accident, producing a considerably increased figure for the respondent's recent income earning activity, the Furzer report provided a rational alternative approach to the assessment of economic loss, one productive of greatly increased damages. It is unnecessary to express a view on the soundness of the alternative. The point is that what counsel for the appellant had referred to as "the base figures that he had been earning for years before hand" did not give a particularly satisfactory basis for forecasting the earning of income after the accident, because the translation of the respondent's earning capacity into income was muddied by interposition of Dynpan and the family trust and because it was necessary to have regard to the evolving business activity.
28 In such circumstances it is well accepted that it is permissible to look to a hypothetical wage rate. So in Dunlany v The Hunters Hill Bus Co Pty Ltd (CA, 12 May 1983, unreported) Moffitt P said -
"To digress, before coming to the third reason, I add that the problem in a case such as the present arises at times in cases before the court where a working owner or partner receives injury and cannot do as much as previously in a business which however changes in character and administration from time to time in such a way that although it is clear that there is a diminution in working capacity and that of necessity there must be some economic detriment to the business, it is difficult, or perhaps impossible precisely to quantify the loss, or demonstrate with precision or perhaps at all a mechanism by which the loss occurs. In the judgment of this Court in Blasetto v Wilson (CA, 17 May 1978, unreported) it was said -
'These losses, present and future, some of which, although contingent, are real, are not susceptible of any satisfactory statistical proof. Insofar as they are being sustained at present, their precise amount is largely masked by other circumstances not casually connected with the plaintiff's injury. This however does not prevent the inference on the evidence in the present case that losses are being properly sustained and will be sustained in the future. If there is a real diminution in earning capacity which it can be inferred is or will cause economic loss, it should not go uncompensated because of the difficulty or, it may be, the impossibility of producing evidence which will precisely quantify it at the date of trial or in the years to come.'
