Future economic loss
49 Relevant to this issue are the following further facts. The appellant was aged 29 at the date of the accident and, at the time of trial was aged 38. He was born in the former Yugoslavia and completed high school in or about 1984. After a year of compulsory military service he commenced the study of electrical engineering. He ceased those studies after approximately one year due to economic problems in Yugoslavia at the time.
50 The appellant migrated to Australia in 1988 and began working in his uncle's business as a gyprock fixer. After visiting Yugoslavia in July 1989 and returning to Australia in November, he continued as an employee engaging in the same type of work as he had performed for his uncle. In 1990 he again worked for his uncle fixing suspended ceilings and partitions. In 1992-3 he passed a trade examination and underwent a business management course as a result of which he obtained a licence as a drywall plasterer. In February 1993 he set up his own business "Tosho Ceilings" in partnership with his wife. She did the administrative work associated with the business and he worked on site with two or three others as well as undertaking quotations for jobs. He incorporated the business in September 1994.
51 The site work undertaken by the appellant was heavy and involved lifting panels for walls above his head and shoulders and then screwing them to a wall or ceiling. The panels weighed from 20-60 kilos.
52 Some weeks after the accident the appellant returned to his business but had continuing problems with his back which caused him to change the way he worked. Instead of carrying out the work of a tradesman with tools, he restricted himself as much as he could to quoting for work and the supervision and organisation of jobs.
53 Over the ensuing years the appellant has continued to have back problems, the nature of which I have detailed above. He has avoided doing the heavier work associated with gyprocking and dry wall plastering. Fortunately, the turnover of the business has increased significantly with time. However, the primary judge found that the company has not always been busy and the appellant has been restricted by the condition of his back from looking for work for himself as a tradesman "on the tools".
54 As the primary judge concluded in the passage from his reasons which I have quoted in [42] above, the appellant's business is not suffering any day to day loss but the fact that he cannot partake in work "on the tools" has resulted in him suffering a diminution of his earning capacity. Doing the best he could on the material before him, his Honour assessed that diminution as equivalent to six months earnings as a gyprock installer. Regrettably his Honour did not quantify that loss. Although the parties had, at the time of the hearing of the appeal, assumed that they would reach agreement on this issue, that has not occurred with the consequence that supplementary written submissions have been filed and the Court now requested to resolve the issue for itself.
55 The appellant submits that the primary judge fell into error in assessing his loss or diminution of his earning capacity as the equivalent of six months earnings as a gyprock installer especially as there was no evidence before him of those earnings. It is conceded by the appellant that his personal and company tax returns from 1993/94 to 2001/02 provide no assistance in this regard as they do not establish the income that the appellant would have earned had he not been injured. Accordingly, it is submitted that this Court should make its own assessment of the damages to which the appellant is entitled for loss of earning capacity: State of New South Wales v Moss (2000) 54 NSWLR 536. In that case Heydon JA, with whom, on this issue, Mason P and Handley JA agreed, observed (at 559 [87]):
"In short, where earning capacity has unquestionably been reduced but its extent is difficult to assess, even though no precise evidence of relevant earning rates is tendered, it is not open to the court to abandon the task and the want of evidence does not necessarily result in non-recovery of damages…The task of the trier of fact is to form a discretionary judgment by reference to not wholly determinate criteria within fairly wide parameters. Though the trier of fact in arriving at the discretionary judgment must achieve satisfaction that a fair award is being made, since what is involved is not the finding of historical facts on a balance of probabilities, but the assessment of the value of a chance, it is appropriate to take into account a range of possible outcomes even though the likelihood of any particular outcome being achieved may be no more than a real possibility."
56 The appellant submits that it is clear that he will suffer some continuing loss of income as a result of the diminution in his earning capacity. There is a real risk, so it is submitted, that in the future he will lose income because he cannot work "on the tools" as a tradesman when his company is not so busy as to require his services in the performance of that work. Furthermore, in the event that the appellant's company was unable to continue in business whether because of the inability of the appellant to carry out heavy work or for other reasons, the appellant would, so it is submitted, be in an extremely vulnerable position so far as being able to obtain work on the open labour market given the restrictions on his activities which the injury to his lower back has caused.
57 Accordingly, it is submitted that damages in the order of $50,000 would "be no more than modest compensation for the appellant's permanent diminution in earning capacity".
58 The respondents draw attention to the following. Firstly, in his Further Amended Part 9 rule 27 Statement of Particulars filed in court on 15 May 1999, the appellant claimed future loss of income estimated at $300 per week net after tax. Although he also claimed in those particulars that he was unable to earn the average adult weekly earnings as identified by the Australian Bureau of Statistics, it was submitted that the appellant should be confined to an estimated loss of $300 net per week.
59 Secondly, as I have already noted, the primary judge assessed the appellant's diminution in earning capacity as equivalent to six months earnings as a gyprock installer. The respondents observe that Ground 3 of the Notice of Appeal only asserts that his Honour erred in failing to calculate the damages in respect of the diminution of the appellant's earning capacity. They contend that that ground does not purport to challenge the finding of his Honour that the appellant's loss was the equivalent of six months earnings as a gyprock installer. Accordingly, it is submitted that it is not now open to the appellant to do so as a consequence whereof his claim should be determined at the rate of $300 per week for a period of six months, a total of $7,800.
60 Thirdly, the respondents submit that the appellant's claim in the sum of $50,000 is not only inconsistent with his claim as particularised in his Part 9 rule 27 particulars, but also with the schedule of damages which was provided by him to the primary judge and which claimed diminution in earning capacity in the sum of $45,000.
61 In his written submissions in the Orange Book, the appellant referred to the primary judge's finding that the appellant had suffered a diminution of earning capacity equivalent to six months earnings as a gyprock installer but had not quantified that loss. "Hopefully", the appellant suggested, "the parties can agree on a number". The respondent concurred with this sentiment. However, the parties were unable to reach agreement as a consequence whereof supplementary written submissions were filed and, as I have observed, the Court was requested to make its own assessment of the appellant's loss under this head of damage.
62 I would not accede to the respondents' submission that the appellant is limited to a claim for $7,800 being $300 per week for six months. In the first place the appellant's Part 9 rule 27 particularisation of his future loss of income (estimated at $300 per week net after tax) was not limited to a period of six months. The assumption in the particulars is that that was a net loss per week for the rest of the appellant's working life subject, of course, to the usual vicissitudes. Furthermore, the appellant claimed that he was unable to earn average adult weekly earnings as identified by the Australian Bureau of Statistics. It is not clear whether that was advanced as an alternative to the $300 per week but in any event there is no suggestion that there was evidence as to what those earnings were.
63 In the second place, although it is true that Ground of Appeal 3 only challenges the primary judge's failure to "calculate" damages, the ground seems to me to be wide enough to include an inferential challenge to his Honour's finding that that diminution was equivalent to six months earnings as a gyprock installer.
64 In the third place, as the respondents themselves point out in their supplementary written submissions, at the trial the appellant claimed damages under this head in the sum of $45,000 which makes it clear that the appellant was not limiting his loss to $300 per week for six months. Finally, there is no suggestion by the respondents that they would be prejudiced by the appellant now seeking to depart from his particulars or a literal reading of Ground of Appeal 3, if departure there be.
65 The primary judge gives no reasons as to why he assessed the diminution in the appellant's earning capacity as equivalent to six months earnings as a gyprock installer. Immediately prior to that finding he had assessed the appellant's general damages in the sum of $35,000 based upon the same injuries and their sequelae as those which he must have taken into account in assessing diminution in earning capacity. I have found that his Honour's assessment of general damages was manifestly inadequate. For the same reasons, I consider that his Honour's assessment of the appellant's diminution in earning capacity as equivalent to six months earnings as a gyprock installer (which, as the respondents submit amounts to $7,800) as equally inadequate and erroneous.
66 In the foregoing circumstances, this Court must assess for itself an amount by which the appellant's earning capacity has been diminished by his injuries and which is, as Heydon JA pointed out in Moss, an assessment of the value of a chance which may or may not come to fruition. There are clearly a number of possible events which could result in the appellant's business failing so that he is required to seek work outside the building industry. Those events may well be outside the appellant's control, for example, an economic recession in the building industry or the inability to obtain appropriately skilled labour.
67 Given that the appellant was only 38 at the time of trial and therefore has a further working life of approximately 27 years before him subject to the usual vicissitudes, I see no reason to differ from the amount of $45,000 claimed by the appellant under this head of damage before the primary judge. In all the circumstances, that figure seems to me to be a fair estimate of the value of the chance that over the next 27 years the appellant will be unable (because of his injuries) to earn what he might have earned had he not been subjected to the injuries he sustained as a result of the respondents' breach of statutory duty.
