• the plaintiff's concession at trial that he was fit and able to do clerical work or something like it, as long as he could get up and move around (Black AB 70 ).
22 The appellant concedes no more than about eight months significant disability, between August 1994 when there was the first complaint of low back pain to Dr Oliver and April 1995 when (following the surgery) he was admittedly able to walk a mile without significant back or leg pain.
23 A critical aspect of the economic loss claim was the plaintiff's evidence that the accident led to low back pain, first noticed towards the end of 1992. No complaint of such pain was made to the plaintiff's general practitioner, Dr Oliver, who saw the plaintiff on several occasions in 1992-1994. It was on 15 August 1994 that the plaintiff first sought advice from Dr Oliver in relation to a complaint of persisting groin pain and low back pain radiating into both legs.
24 The learned trial judge nevertheless accepted that the plaintiff had suffered a lumbar injury which ultimately required surgery (in 1995) and which continues to be a significant factor affecting the plaintiff's employability. This finding was based upon acceptance of the plaintiff generally as a witness of truth; a note of Dr Oliver of 29 September 1992 raising the possibility that groin pain then being suffered might be referred back pain (see Red AB 49, 58); the opinion of Dr Oliver given in 1996 that lumbar injury had been suffered in the accident; and the opinions of Dr Chen and Dr Wolfenden that the accident had contributed to the deterioration of the plaintiff's back condition.
25 In February 1995 neurosurgery was performed by Dr Segelov and the plaintiff was in hospital for 10 days. By April 1995 he was able to walk one mile without significant back or leg pain.
26 Dr Chen examined the plaintiff for Comcare in May 1995. She formed the view that the plaintiff had responded well to the surgical procedure with a diminution of right leg pain, and that while he may continue to have lingering intermittent back pain, it was anticipated that with appropriate rehabilitative measures his physical tolerances could improve. She was of the opinion that the plaintiff was fit to perform full-time clerical and administrative duties with restrictions from repetitive heavy manual handling and prolonged and repetitive truncal bending and twisting.
27 Dr Oliver reported in February 1997 that the plaintiff had had a good recovery from surgery and that his MRI scan was normal. He opined that the plaintiff was permanently restricted in being able to sit or stand for long periods of time, and said that he should not undertake heavy lifting or carrying or repetitive bending, or attempt to negotiate rough terrain, either on foot or in a four-wheel drive vehicle, or climb up or down ladders (these being activities encountered in his former duties as a customs officer). Dr Oliver thought it unlikely that further surgical intervention would be required although the plaintiff would require sessions of physiotherapy from time to time.
28 There was little difference in the opinions of Dr Oliver and Dr Chen and the trial judge readily accepted both.
29 His Honour also appears to have accepted the evidence of Dr Wolfenden, a neurologist who saw the plaintiff at the request of the appellant. Dr Wolfenden thought there may have been some pre-existing degenerative changes in the lumbar spine but not symptomatic, and that the incident on 14 April 1992 was probably of considerable jarring and aggravated changes in the symptoms precipitated. He was also of the view that the plaintiff was unfit for work involving bending, lifting or prolonged sitting or standing, and could only do light work where he was free to move around at will. Dr Wolfenden considered the plaintiff to have a permanent impairment of the function of his back equivalent to approximately 25% of a most extreme case and a 10% loss of the efficient use of his right leg at or above the knee.
30 In my view it was well open to the primary judge to accept the genuiness of the long term injury to the lower back in consequence of the accident. It was consistent with the accident, there was support from the September 1992 diagnosis of Dr Oliver, the plaintiff was accepted generally as a witness of truth, and the causal link was supported by medical opinion which the trial judge accepted. This aspect of the appellant's challenge fails.
31 The more difficult issue is the judge's conclusion that the primary facts supported a finding of 50% loss of earning capacity. Senior counsel for the appellant accepted in argument (Tr p21) that the critical issue pressed by the appellant is whether the medical opinion of Dr Chen, accepted by his Honour, justified the conclusion that there was an ongoing loss of earning capacity to the level of 50%.
32 Before us, the plaintiff emphasised that the task confronting the trial judge was assessing lost earning capacity as distinct from lost earnings. It was submitted that there was ample evidence that the earning capacity had been significantly affected. It was further submitted that the onus lay upon the defendants in the court below to show that alternative employment would have been available to the plaintiff, assuming (correctly, I believe) in the plaintiff's favour that the decision to give up his employment with ACS did not in itself represent a failure to mitigate damages. The plaintiff relies upon the general principles in Watts v Rake (1960) 108 CLR 158 and Purkess v Crittenden (1965) 114 CLR 164. See also Luntz, Assessment of Damages for Personal Injury and Death 3rd ed [1.9.23]-[1.9.27].
33 The medical evidence accepted by the trial judge and the plaintiff's own admission show that the plaintiff is fit for full time clerical and administrative duties so long as he is not required to sit or stand for long periods of time. The proviso leaves a broad field of gainful employment available to the plaintiff.
34 The broad band of the plaintiff's post-operative work capacity distinguishes this case from those in which an evidentiary onus shifts clearly to the defendant to show that jobs are reasonably available for a severely disabled plaintiff. The Court cannot close its eyes to the difficulties of obtaining employment generally, especially in country centres. Nevertheless, I have concluded that, with the ultimate onus resting upon the plaintiff, the finding of 50% incapacity in the sense of diminution productive of financial loss cannot be sustained.
35 We are faced, like the trial judge, with a man in his mid-40s who gave up secure employment for reasons unconnected with the accident, in circumstances where the Commonwealth would have had a duty to continue providing suitable employment (cf Safety, Rehabilitation and Compensation Act 1988 (Cth), s40). The plaintiff has to date made virtually no attempt to find gainful employment consistent with his medical condition since the accident. Latterly, this was because he was pursuing a new career as a sports coach, despite expressed apprehensiveness about his capacity to do the physical side of such a job. In all the circumstances, the plaintiff can take very little comfort from his pattern of actual earnings as providing any real indication of his capacity to earn in consequence of his disabled condition. That capacity is untested (save (a) where the plaintiff worked without loss of income with ACS and (b) in relation to taxi driving which was unsuitable because it involved a 12-13 hour shift (Black AB 64)).
36 The plaintiff accepted that he was able to do clerical work as long as he could get up and move around. No evidence was led to suggest that clerical work was unavailable generally, or in the Coffs Harbour area in particular, that would have catered for the plaintiff's need to get up and walk around from time to time.
37 Nothing suggests the lack of necessary intellectual capacity to do a broad range of clerical jobs. The plaintiff's earlier work experience did not involve heavy physical work.
38 I have concluded that the proper level of accident-induced incapacity productive of financial loss is 25%, save for the 12 month period in 1994-95 when 100% incapacity was accepted by the trial judge. Otherwise I would not disturb the reasoning of the trial judge referable to economic loss. The parties should recalculate damages accordingly.
