She said that she continued to do that until Mr Azzopardi came to help. She identified that as being a period of about two years. She said that she took over again after Mr Azzopardi left until their daughter started.
55 Having made no reference to this evidence, all of which was relevant, it is unsurprising that his Honour then made no finding as to the extent of Mrs Zahra's contribution. However, that was relevant evidence that his Honour needed to assess and his failure was not only an error in the process of fact finding: Waterways Authority v Fitzgibbon at [130], it also appears to have led him into error in thinking there were unanswered questions. Contrary to his Honour's finding that it was unexplained as to why it took so long to have Mr Azzopardi start work, Mrs Zahra explained that she did the work during that period. She said however that she became very busy with the other things and became cranky doing the work on the farm (Transcript 117). There thus became a need to employ someone to assist. Mrs Zahra was not cross-examined, nor was the appellant, as to why they did not employ Mr Azzopardi or some other person in the period of time that Mrs Zahra was doing the work. His Honour failed to appreciate the effect of Mrs Zahra's evidence. Further, it appears his Honour used this perceived omission in the appellant's case to make an inferential finding that the appellant must have been doing the work in this period and thus must not have been incapacitated as alleged. This involved a credit finding, which, however, was based on an erroneous understanding of the evidence.
56 Further, his Honour appears to have misunderstood what task he was undertaking in assessing Mrs Zahra's contribution. I have already pointed out that he failed to make any reference to her evidence or to make any finding as to the extent of the assistance she provided. His only comment was, "As his wife shares the partnership there can be no claim for her labour" (Judgment 23). There was no such claim. But in any event, his Honour failed to deal with the relevance of the business being conducted in partnership.
57 A claim for economic loss requires the Court to determine the extent of any interference in earning capacity caused by the injury sustained in the accident. Having made that assessment, the Court is then required to determine the economic loss that a plaintiff has suffered and will suffer as a result of that interference with economic capacity. The fact that Mrs Zahra was in partnership with the appellant is a relevant consideration in determining the extent to which interference with economic capacity has resulted in economic loss. It is not a relevant consideration in determining the extent of the interference with the economic capacity. His Honour did not make that distinction. In fact, he did not deal with the income earned from the farm at all. The principles to be applied in assessing the award for economic loss in such circumstances were stated by the High Court in Husher v Husher (1999) 197 CLR 138; [1999] HCA 47. The trial judge made no reference to those principles.
58 Having made the findings as to the extent of assistance that the appellant had on the farm, his Honour then stated that he accepted that the appellant injured his lower back and that an annular tear at L3/4 imposed some limited physical restrictions upon his working on the chicken farm and doing the welding. He commented that the injury was permanent according to the medical evidence. His Honour then said:
"I consider that the most appropriate approach to economic loss, given my findings above, is to allow a cushion. The welding work is essentially bench work and not heavy and on the basis of the medical evidence and the video evidence I consider the [appellant] can continue to perform that work with little restriction. The restrictions that he does have preclude him doing consistent heavy work and for this restriction an allowance must be made in monetary terms. I consider the sum of $45,000 appropriate to reflect the [appellant's] economic loss from the date of accident to date of trial for the future in the overall circumstances." (Judgment 13)
59 The appellant complains that his Honour failed to explain the basis upon which he did so and in any event the sum allowed was inadequate. Senior Counsel for the appellant informed the Court that if the sum of $45,000 was extrapolated over the period of the appellant's working life, it amounted to an award of about $100 per week. Counsel for the respondent did not disagree with this computation.
60 His Honour was entitled to make an award by way of a "cushion". However, in doing so his Honour was not thereby relieved of his obligation of giving adequate reasons for decision. The appellant's claim for economic loss was both substantial and detailed. It was for his Honour to determine the extent to which it was made out, even if, in the end result, an appropriate award was by way of a "cushion".
61 The appellant claimed a past and future economic loss based on a loss of actual income as well as an increase in expenses from the date of the accident. The appellant's evidence was that in the three months preceding the accident he had earned approximately $17,500 by way of contract welding and approximately $21,500 by the sale of chicken manure. In the three months following the accident the earnings from the contract welding work, $10,500, were paid to his son who had undertaken the work for him. There were no sales of chicken manure in this period.
62 The appellant contends that he had thereby demonstrated a loss in this period of $38,855 or nearly $3000 per week. These figures did not need to be taken at face value by his Honour. For example, the evidence demonstrated that substantial cleaning out of chicken manure occurred at the end of each growing period and that the contract welding work was sporadic. However, the evidence does disclose that the appellant had significant earnings from both and some attempt should have been made by the trial judge to quantify those earnings and determine to what extent the appellant's incapacity resulted in economic loss.
63 In this regard there was evidence to which I have referred that the appellant had been unable to work for a period of six to 12 weeks following the accident. His Honour failed to deal with any of this evidence and failed to make any differentiated award for past economic loss, even for this period. In circumstances where his Honour accepted that the appellant had an annular tear that was attributable to the accident and there was no cross-examination of the appellant to the effect he was not off work during this period, nor incapacitated, or that he did not suffer the economic loss alleged, there appears to have been no good reason not to have awarded a full economic loss for this period. It was a matter for his Honour to determine whether the period of total incapacity and consequential loss was six or 12 weeks or some other period.
