The report was otherwise uninformative in relation to the degree of accident-related disability.
31 In terms of his social skills, his mother (who was not cross-examined) stated (at par 3) that before the accident he was "an enthusiastic sports man who particularly enjoyed soccer and had ambitions to be a professional player. He was an even tempered teenager and was not prone to mood swings. He was an average student who could have tried harder. However, there were no problems with his attendance at school and he was never in any trouble with his teachers…. Socially, Alex was a well adapted young man who had a lot of friends."
32 Mrs Najdovski described the situation after the accident in the following terms (at pars 5-7):
"He is prone to lose his temper very quickly. He has massive mood swings and can experience many moods in the same day. Before his accident, I could leave my daughter, Angel, in Alex's care while I went to work. I could trust her in Alex's care with no concerns. Since his accident, I have been reluctant to leave Angel and Chad with Alex. Very often and for no apparent reason, Alex loses his temper with them. He starts screaming at them and will usually take off into his room. … Alex's behaviour towards me has also changed. I get the feeling that Alex no longer respects me. He screams at me nearly every day ….
Since the accident, Alex spends most of his time in his room sleeping or on the computer. He would spend all day in there if I let him."
33 His mother said that he was easily distractable and needed help looking after himself. In relation to his physical condition, she stated at pars 15-17:
"Alex's physical state has also changed as a result of the accident. Before the accident, he was a very solid, fit young man. …
He is now very skinny and has lost a lot of strength. One major change in Alex's major physical appearance has been to his eyes. … Since Alex came out of the coma, I have noticed that his eyes have been dull and he looks sort of dazed. His eyes have not changed since this time.
Alex's speech has also been affected as a result of his injuries. At times he can be difficult to understand, especially when he is angry or excited."
34 A report prepared for the defendant's insurer by Dr Mary-Clare Waugh, Staff Specialist in Paediatric Rehabilitation Medicine at the Children's Hospital, dated 20 November 2001, stated (at p 1):
"Alex was discharged from hospital on 25-1-01 and at this stage he had difficulties with fatigue, poor balance, difficulties with his memory, neck pain and some mild right sided weakness. Alex had an occipital pressure area as a complication of his management in [the intensive care unit].
35 Dr Waugh noted that the appellant had had a neuropsychological assessment on 28 March 2001 and that reported changes since the accident "included fatigue, word finding difficulties, poor memory and some mood alterations". The report continued:
"Alex was reviewed in the Brain Injury Clinic on 10-10-01 and at this time he reported that he has less fatigue and has only had a couple of headaches since discharge. Occasionally he has postural hypotension resulting in dizziness. He reports that he is easily frustrated by school performance difficulties and being restricted with his physical activities. … He continues to note difficulties with his memory. Alex also reported pain in his lower back and a tender lower lumbar spine. … Stretching seems to increase the pain and resting helps. In addition Alex complains of pain in his neck …. Both of these back and neck pain problems have emerged since his accident."
36 On 13 November 2002 Dr Waugh prepared a further report noting that the headaches and fatigue by then provided "minimal problems": at p 1. She also noted that the appellant was "interested in car mechanics or being a carpenter". He reported in October 2001 that physiotherapy had improved his neck and back pain, but in November 2002 he reported a recurrence of neck pain and lower back pain. Dr Waugh noted that the appellant's local doctor was considering a review by a psychiatrist to investigate the appellant's "personality changes since the accident". Dr Waugh stated:
"In conjunction with a psychological assessment a repeat neuropsychological assessment of his cognitive and thinking abilities would also be appropriate."
37 She noted that he was playing soccer but under pressure his motor coordination skills had deteriorated and he had difficulty with anger control, which "led him to be an easy target and resulted in fights". Other physical problems appeared to be improving.
38 In July 2004 the appellant attended a clinical psychologist, Peter J Rawling, for a neuropsychological assessment. In a report dated 2 August 2004, Mr Rawling said (at p 5):
"The results of the current neuropsychological assessment, now over three years post injury, were very similar to those returned at initial assessment. Again, a weakness was evident in reading and language based skills but he demonstrated average or better ability on tests of non-verbal intelligence, memory and executive functioning. His working memory span was maintained but there was clear evidence of a persistent slowing in the rate of information processing and divided attention. Given the severity of the head injury, such attentional deficits were only to be expected.
It was noted that Dr O'Neill has assessed the whole person impairment in terms of a mental status impairment of 14%. I would agree with this assessment of the mental status impairment but I suspect that the behavioural changes secondary to his frontal lobe damage represents the more significant source of disability. He had lost a great deal of his former drive and though bored and unhappy with his life style, he had made no effort to change it. He became depressed and had admitted to his father that he had thought of suicide. His irritability on the football field made it impossible for him to continue in the game. On the basis of these behavioural changes, I considered him to have an Emotional and Behavioural Impairment in the 15-29% range - 'Moderate limitation of some but not all social and interpersonal daily living functions'. I would assess his impairment as being at the middle of this range - ie 22%."
39 In September 2005, the appellant saw a clinical and consulting psychologist, Dr Steven Dragutinovich. In a report dated 24 September 2005, he stated, under the heading "Prognoses" (at p 15):
"The clinical prognosis for further cognitive recovery from neurotrauma is poor as Alex is now well over the 2 year period during which time it is generally considered that recovery from neurotrauma plateaus. Treatment is aimed at limiting the adverse effect of Alex's neurotrauma related behaviours which, along with the stabilising influence of living with his parents and family, will assist Alex in the immediate foreseeable future. When Alex leaves home, however, and is away from the external structure, routine and stability provided by family, the likelihood is that, unless he has an understanding partner and employer, problems will occur as he interacts with others.
The danger is that Alex will drift to the periphery of society, become marginalised, and increasingly feel outcast, particularly if he does not obtain further sources of external stability in the form of work which, in my opinion, he may be able to get but will experience significant difficulty in keeping. For this reason the realistic vocational prognosis is guarded."
40 In August 2004, the appellant saw Professor Peter Disler, a consultant physician and Professor of Rehabilitation Medicine at the University of Melbourne. Professor Disler expressed concern at the lack of progress but noted that progress in rehabilitation was "going to be challenging": Report, 10 August 2004, p 12. He noted that the appellant presented as a "very thin young fellow" and that his father had drawn attention to the fact that he was "previously well built and fit, but had lost a lot of weight since the accident": Report, p 9.
41 In August 2005 the appellant obtained a detailed and thorough report from Ms Lauren Alach, an occupational therapist. Many of her recommendations, which were detailed and specific, related to possible requirements for assistance otherwise than in relation to employment. However, particular matters related to his physical circumstances, cognitive status and future employment.
42 In relation to his physical status, Ms Alach reported:
"4.3 … His residual physical problems include pain in his neck, back and left knee and weakness on the right side of his body. This affects his performance of repetitive daily living and work tasks and has limited his return to soccer.
4.4 I agree with Professor Disler's recommendation that a strengthening program is essential for Mr Najdovski due to his postural asymmetry resulting from right sided weakness and left knee pain which aggravates his neck and back during strenuous activities.
…
4.9 His current physical problems are likely to impact on his return to his chosen employment options. The impact of these limitations should reduce following implementation of a physical program."
43 There was some difference in the evidence as to the reasons for the appellant discontinuing soccer. The appellant expressed the view that he now had "two left feet" (presumably being his non-dominant side), whereas his father was clear that he stopped him playing because of his irritability and lack of anger control on the field. The two may, of course, be related.
44 In relation to "cognitive status", Ms Alach reached the following conclusions:
"5.8 Although Mr Najdovski continues to experience some problems with his working memory and concentration, he is starting to compensate for deficits and his performance is sufficient to enable him to perform practical work and leisure tasks."
45 In relation to future employment, she expressed the view that before considering employment in a physical trade such as carpentry, he should embark on the fitness and strengthening program previously outlined. She also stated that he appeared "very eager and motivated to undertake this program to assist his return to work": Report, 26 August 2005, par 13.8. She agreed with Professor Disler that a "vocational rehabilitation program" was essential to allow the appellant to find appropriate employment and concluded that he was "likely to require a more intensive and closely monitored program than [that] previously provided" by the Commonwealth Rehabilitation Service: at par 13.9. She continued at pars 13.10-13.11:
"He has demonstrated the ability to operate tools and perform the physical components of carpentry tasks. Should he continue to experience back, neck and knee pain from constant work, he may need to reconsider his working hours, working three to four days a week or fewer hours each day to manage his pain. These options may not be available during a carpentry apprenticeship.
Once he completes an apprenticeship, however he would be better able to control his hours if he starts his own business as he has expressed a desire to do. The impact of his cognitive deficits on his ability to set up and manage a business would need to be considered."
Economic loss: principles of assessment
46 The general law principles in relation to the assessment of damages in motor accident cases are subject to the operation of Chapter 5 of the Motor Accidents Compensation Act 1999 (NSW) ("the MAC Act") and those provisions of the Civil Liability Act 2002 (NSW) identified in s 3B(2). So far as the latter Act is concerned, the only relevant provision was s 15C, relating to loss of superannuation entitlements, to which further reference will be made below.
(a) Future economic loss
47 In relation to the MAC Act, the principal section of present relevance is s 126, which provides:
" 126 Future economic loss - claimant's prospects and adjustments
(1) A court cannot make an award of damages for future economic loss unless the claimant first satisfies the court that the assumptions about future earning capacity or other events on which the award is to be based accord with the claimant's most likely future circumstances but for the injury.
(2) When a court determines the amount of any such award of damages, it is required to adjust the amount of damages for future economic loss that would have been sustained on those assumptions by reference to the percentage possibility that the events concerned might have occurred but for the injury.
(3) If the court makes an award for future economic loss, it is required to state the assumptions on which the award was based and the relevant percentage by which damages were adjusted."
48 This language is reflected in s 13 of the Civil Liability Act, a provision which has been considered in a number of cases in this Court: see, eg, Macarthur Districts Motor Cycle Sportsman Inc v Ardizzone [2004] NSWCA 145; 41 MVR 235; Penrith City Council v Parks [2004] NSWCA 201; Nominal Defendant v Lane [2004] NSWCA 405; Kallouf v Middis [2008] NSWCA 61 and Roads and Traffic Authority of NSW v Chandler [2008] NSWCA 64.
49 Two factors should be noted for present purposes. First, s 126 does not apply to the assessment of past economic loss. Secondly, the percentage adjustment for events which "might have occurred but for the injury" may take into account not merely the normal vicissitudes of life, but also the chance that the most likely future circumstances would not have occurred, as assessed in accordance with the principles established in Malec v JC Hutton Pty Ltd (1990) 169 CLR 638: see Chandler at [56]-[57].
(b) Attendant care services
50 The assessment of damages for attendant care services, both past and future, are to be governed by s 128 of the MAC Act. Section 128(3) provides a threshold, below which no compensation can be awarded for attendant care services. The threshold is calculated by reference to the number of hours per week and the period over which the services are provided. The appellant argued that his Honour was in error in failing to calculate the amount on account of services by reference to a specified number of hours per week over a specified period. The respondent argued that once the threshold had been satisfied (which was not in issue) it was a matter for the trial judge to assess compensation as he saw fit. Thus, it was open to the trial judge to identify a global amount without reference to a particular hourly rate or a particular number of hours.
51 In principle, it may be that such a calculation is permissible. However, sub-ss 128(4)-(6) impose a prima facie cap on the amount of compensation, the cap being ascertained by reference to average weekly earnings. Where the services are provided at less than 40 hours per week, the amount must be calculated at an hourly rate: sub-s (5). Accordingly, it seems likely that the respondent could insist on an hourly rate calculation in order to ensure that the cap was not exceeded. However, if the cap is not in issue, the basis of calculation is not otherwise constrained by the statute. In practice, it gives guidance as to reasonable rates of payment for such services.
(c) Superannuation loss
52 The third question which arose as a matter of construction concerned the calculation of lost superannuation entitlements, pursuant to s 15C of the Civil Liability Act. That section states:
" 15C Damages for lost superannuation entitlements
(1) The maximum amount of damages that may be awarded for economic loss due to the loss of employer superannuation contributions is the relevant percentage of damages payable (in accordance with this Part) for the deprivation or impairment of the earning capacity on which the entitlement to those contributions is based.
(2) The relevant percentage is the percentage of earnings that is the minimum percentage required by law to be paid as employer superannuation contributions."
53 It has generally been assumed that the calculation required takes as the "relevant percentage" the figure specified in the Superannuation Guarantee (Administration) Act 1992 (Cth) which has, since the 2002/2003 tax year, been 9% of the employee's gross ordinary time earnings: see Zorom Enterprises Pty Ltd v Zabow [2007] NSWCA 106 at [72] (Campbell JA). (For ease of calculation, and because damages are assessed by reference to earnings net of tax, the calculation is sometimes undertaken on the basis of 11% of net earnings.)
54 The respondent contends, correctly, that the relevant percentage is therefore 9%. However, he notes that the damages payable for deprivation or impairment of earning capacity must be based on net earnings and, accordingly, the cap on superannuation losses must be calculated by applying 9% to net earnings.
55 Read literally, the section undoubtedly bears that construction. If the section were intended to provide an arbitrary cap, that reading might be appropriate. If, on the other hand, the section is merely intended to provide a mechanism for calculation of an otherwise uncapped amount, the literal construction is inappropriate.
56 To determine the purpose of s 15C, it may be permissible to consider its legislative history: see Interpretation Act 1987 (NSW), ss 33 and 34; Harrison v Melhem [2008] NSWCA 67 at [172] (Mason P, Spigelman CJ, Beazley and Giles JJA agreeing); cf Shorten v David Hurst Constructions Pty Ltd [2008] NSWCA 134 at [10]-[27]. In my view, the provision is ambiguous in the sense that it has two possible meanings and is obscure because it is unclear which meaning should apply. Accordingly it is legitimate to consider extrinsic material which is capable of assisting in ascertaining the meaning of the provision, pursuant to s 34. That approach is also available under general law principles, without the need to identify ambiguity: CIC Insurance Ltd v Bankstown Football Club Ltd [1997] HCA 2; 187 CLR 384 at 408 (Brennan CJ, Dawson, Toohey and Gummow JJ).
57 Such assistance may be derived from the Final Report of the Review of the Law of Negligence, published in September 2002 ("The Ipp Report"). The Report dealt with the calculation of loss of superannuation benefits at pars 13.128-13.133. The recommendation made in the Report (recommendation 58) is clearly reflected in the present form of s 15C. However, the concern of the Committee was to reconcile the differing approaches to such a calculation revealed in Roads and Traffic Authority v Cremona [2001] NSWCA 338; 35 MVR 190 and Jongen v CSR Ltd [1992] Aust Torts Rep ¶81-192 (WASC). In Cremona, this Court calculated the relevant loss by reference not merely to the employer contributions, but also to income and capital growth which those contributions would have generated in a superannuation fund. That approach was rejected in the Report. The alternative approach adopted by Anderson J in Jongen was considered preferable but was also thought to be "undesirably complex": at par 13.132. Although not disclosed by the Report, the basis of the rejection appears to be that Anderson J considered that the taxation at a concessional rate of contributions to the fund should also be taken into account: see generally Zorom at [64]-[65]. The purpose of the recommendation of the Report was to "bring about certainty, simplify matters and reduce costs": at par 13.133. As a result, "[s]ophisticated calculations by accountants and actuaries would be rendered unnecessary, opportunities for disagreement between the parties would be reduced, and out-of-court settlements of claims would be facilitated": par 13.133. It is therefore clear that the purpose of s 15C, as envisaged in the Ipp Report, was to simplify calculations and not to impose an arbitrary cap on the amount allowed by way of superannuation entitlements.
58 The ambiguity of purpose may thus be resolved by rejecting the literal interpretation proposed by the respondent and allowing the calculation of superannuation contributions to be made by taking the relevant percentage of gross ordinary time earnings which are treated as the value of lost earning capacity.
Assessment of loss
(a) Past economic loss
59 It is convenient to commence with the calculation of past economic loss. As the case was presented at trial, it was known that the appellant had continued to the end of Year 10 and was thus unlikely to have entered the workforce until the beginning of 2002. On the basis that he would obtain an apprenticeship as a carpenter, his loss was calculated on a scale commencing at $10,964 for the 2002 year and moving to $19,654 for the 2005 year, giving a total claim of $61,273. Having noted the amounts claimed, his Honour reached the following conclusion (Judgment at p 9):
"The manner in which he would have entered the workforce either as an apprentice or a young person seeking to gain experience in the construction industry suggests that the predictions of his past loss are over estimated, especially for the years 2002 and 2003. In my opinion, his past loss is a matter of speculation not capable of precise assessment and I propose to allow a global figure of $30,000 for the loss of opportunity to work as a labourer or apprentice during that time."
60 As Malec recognised, any assessment of a past hypothetical proposition must be speculative to a degree. However, there was evidence before his Honour that, prior to the accident, the appellant was committed to commencing such a career, that he had shown genuine aptitude as either a carpenter or a mechanic, that he had sought and obtained part-time work whilst in Year 9 at school, and that he was energetic and fit. There were in substance two bases upon which he could have discounted the possibility that the appellant would obtain an apprenticeship immediately after leaving school. The first was that apprenticeships were hard to come by and the second that young people may be inclined to change their minds or abandon a career once embarked upon for reasons which are not readily foreseeable. However, the figure chosen by his Honour meant that the appellant would not have commenced his apprenticeship for approximately two years after leaving school and would not have obtained alternative (and probably better remunerated) employment in the meantime. In the absence of any evidence as to the unemployment rates in the Illawarra area or the paucity of apprenticeships available in those years, such a heavy discount was unjustified.
61 There was no suggestion that his Honour considered there had been a failure to mitigate the appellant's loss. Had such an issue been raised it would have been necessary for the defendant to establish the facts on which such a finding might be based. That exercise was not attempted. Rather, there was evidence that the appellant had obtained two placements on a trial basis. The first ran for three weeks; the second lasted only a week: in each case the appellant abandoned the placement due to cramps and back pain. It was not suggested that these failures derived otherwise than from a combination of physical and behavioural changes consequent upon the accident.
62 Such evidence as there was in relation to the labour market in the Illawarra supported the view that the Illawarra had an unemployment rate higher than the State average for March 2003, but suggested that employers in the building industry might well take on a young man in the position of the appellant and, if he proved successful, put him on as an apprentice after a few months employment. The Labour Market Analysis Report, prepared by a rehabilitation counsellor in May 2003, noted that the overall size of the building industry by reference to occupation was "large" with workers under 25 years holding about 93% of jobs and teenagers holding 51% of jobs: Report, 15 May 2003, p 2. The counsellor noted:
"Only one position was advertised on the Internet vacancy sites over a three-week period however following contact with labour hire companies … and various employers it was concluded that there is currently a demand for Apprentice Carpenters and Trade Assistants. The demand however tends to be very unstable declining rapidly during downturns in the building industry. The potential for new jobs is average and the recruitment of apprentices should continue at close to present levels for that reason."
