7 Unfortunately, there are a number of inconsistencies in that section of the judge's reasoning with the effect of s.138AB(38)(f) and the decision in Barwon Spinners.
8 To begin with, there is the judge's reference in paragraph 20 of his reasons to the salaries which were being earned by truck drivers as at the time of the hearing. As has been seen, s.134AB(38)(f) requires a comparison of the respondent's post-accident earning capacity with his pre-accident earning capacity, determined such that the latter is to be calculated by reference to the gross income (expressed as an annual rate) that the respondent was earning or was capable of earning from personal exertion or would have been capable of earning from personal exertion during that part of the period which, starting three years before the accident and finishing three years after the accident, most fairly reflects the respondent's earning capacity had the injury not occurred. It seems to us, however, that whatever truck drivers may have been earning more than five years after the accident was irrelevant to these calculations unless it were to be used as a basis from which to infer the amount that the respondent might have been capable of earning in the three years following the accident, and it is plain that that is not the way in which the judge applied it.
9 Secondly, and for the same reasons, the comparison undertaken in the first sentence of paragraph 23 of the reasons - between what other truck drivers were earning as at the end of 2005 and what the plaintiff returned as his income for the year ended 30 June 2005 - was irrelevant. It appears also to have been informed by an assumption that the amount of income returned by the taxpayer as his assessable income for the year of income ended 30 June 2005 was necessarily identical to his earning capacity expressed as an annual figure. It may be noted in passing that there were substantial issues, which the judge did not resolve, as to whether the respondent had returned all of his assessable income for tax purposes and, if he had, whether he had a capacity to earn more than he said he earned.
10 In the third place, the statement in the third sentence of paragraph 23 of the reasons - that "the legislation refers to a comparison of earning three years prior to the injury and then three years post injury" - is not to be found in the legislation. As has been noted, it calls for a comparison of the respondent's after injury earning capacity with his without injury earning capacity, as described.
11 The same error is repeated two sentences later with the statement that "a strict application of the three-year prior/post injury earnings only allows for a comparison to be made in respect of one year of post-injury earning", and in turn that leads to the comparison of earnings for the two years before the accident and the two years following the accident which is set out in the latter part of paragraph 23 of the reasons.
12 Finally, and consequently, it is plain that the conclusion expressed in the last sentence of paragraph 23 of the reasons is misplaced. We consider that it is simply not apparent that if "one deletes the two years in which the plaintiff returned nil income from personal exertion and takes into account his actual earnings in the period of three years post injury it is clear that he meets the 40% impairment of earning capacity".
13 In short, it cannot be known whether the respondent meets the 40% impairment requirement test until and unless one has carried out the comparison required by s.134AB(38)(f) of the respondent's after injury earning capacity with his without injury earning capacity determined as described. That comparison, however, was not undertaken in this case.
14 In the course of argument, it was conceded by the respondent's counsel, rightly, we think, that the judge had erred in the respects which we have identified, and it was accepted, therefore, that the matter must be remitted to the County Court for redetermination according to law.
15 In case, however, it may be of assistance to the judge of the County Court who next deals with the matter, we make the following further observations about the reasons for judgment in this case.
