The appellant's appeal on damages
7 The primary judge assessed the appellant's non-economic loss at 50% of a most extreme case resulting in an award of $114,175. He allowed $37,385.76 for agreed out of pocket expenses, which included substantial amounts paid by the worker's compensation insurer for rehabilitation. He allowed for past care at the rate of three hours per week at $18 an hour resulting in an award of $18,154, but for the future only one hour a week at that rate for an award of $16,448. He assessed the appellant's past economic loss at $330 per week with a residual earning capacity of $122 resulting in an award of $115,830, and a Fox v Wood component of $27,432. He allowed $58,659 for future medical and pharmaceutical expenses. He assessed the appellant's future loss at $250 per week with a residual earning capacity of $252 for an award of $130,515. There was a consequential award for loss of superannuation of $23,450.
8 The total award of $542,848.78 was reduced by worker's compensation benefits of $202,078.68 to produce a judgment for $340,770.10. Unfortunately for the appellant this was less than the $350,000 the respondent had formally offered by way of compromise on 17 December 2004 prior to the trial which began on 31 January 2005. His Honour's costs orders leave the appellant paying his own and the respondent's costs from the date of the offer. Costs are likely to absorb a substantial part of the appellant's damages and this has encouraged the search for error.
9 The appellant has not worked since giving up his employment with the respondent. The primary judge found that his exposure to wool dust was a material contributing factor to the development of his asthma. However, the appellant smoked tobacco and cannabis which Dr Crawford said frequently led to significant airway narrowing which was usually progressive with little reversibility either spontaneously or with medication (Blue 1/148). Dr Corte said that the appellant's asthma was mild to moderate in severity. The appellant had also developed features of a chronic anxiety depressive disorder which Dr Clark said (Red 39) involved moderate impairment and aggravated his asthma.
10 The primary judge's assessment of the appellant's non-economic loss took into account the fact that his asthma was permanent and his anxiety depressive disorder was likely to continue. He declined to award damages for the increased disability due to smoking cannabis because the appellant had made a deliberate decision to reject medical advice that he should stop.
11 In assessing the appellant's past and future economic loss his Honour accepted Dr Crawford's evidence but took into account the nature of his former employment and lack of skills in arriving at an average past loss of $330 per week. In his first judgment of 22 April 2005 he applied the normal discount of 15 percent for vicissitudes.
12 In a second judgment of 16 May 2005 his Honour again referred to Dr Crawford's evidence that the smoking of tobacco and cannabis worsens the symptoms of asthma and accelerates the loss of lung function. He found that smoking was making a significant contribution to the appellant's illness. He said:
"I consider having reviewed the evidence of Dr Crawford and the evidence of Dr Clark that it is appropriate in view of the appellant's continued smoking of tobacco and marijuana to make a deduction other than the normal 15 percent for the vicissitudes. I take into account in considering this matter the fact that the appellant has had difficulty in reducing and eliminating the tobacco habit. I have also taken into account that the appellant would appear to be determined to continue to smoke cannabis."
13 The primary judge found that the aggravation of the appellant's condition due to smoking
"… could result in the appellant's ceasing work at a time other than the normal retiring age. I have also taken into account what has been referred to as the appellant's emotional state and that if his condition was worsened or was brought about in any event as a result of smoking of tobacco or cannabis, he would be unlikely to continue working past the age of 65. I consider the appropriate discount for vicissitudes to be 30 percent."
14 The respondent relied on the appellant's contributory negligence before and after he developed respiratory symptoms. His Honour rejected this defence, and insofar as it was based on the appellant's conduct before he developed respiratory symptoms nothing more need be said.
15 A defence of contributory negligence may also be based on a plaintiff's failure to take reasonable care for his own safety after he has been injured as a result of the respondent's negligence: Commonwealth of Australia v McLean (1996) 41 NSWLR 389, 398. This part of the defence was based on the appellant's conduct in continuing to smoke tobacco and cannabis after he had developed respiratory symptoms and had been strongly advised by Dr Crawford to give up both.
16 The primary judge acknowledged that there was no evidence of the extent that smoking tobacco and/or cannabis had added to the effects of the appellant's asthma. His conclusion on this issue was as follows:
"On the evidence before me there may well have been aggravation of the injury, but I consider that the evidence clearly shows that the inhalation of wool dust was a material contributing factor to the asthmatic condition in which the appellant suffers. The smoking of tobacco and marijuana may have aggravated his condition, but it has not broken any chain of causation. I am not satisfied that the respondent has proved that the appellant was guilty of contributory negligence in continuing to smoke cigarettes and/or other tobacco products and/or cannabis."
17 Although the respondent did not cross-appeal from the findings on contributory negligence, there are obvious problems with some of his Honour's reasoning. Findings that the respondent's negligence was "a material contributing factor" and the appellant's contributory negligence "has not broken any chain of causation" do not preclude a further finding that the appellant's contributory negligence was also a cause so that apportionment was required.
18 Nor was apportionment excluded by the absence of evidence of the extent to which the smoking of tobacco and cannabis had added to the appellant's asthma. In this, as in other questions of damage where precise evidence is not available, the Court must simply do the best it can. The primary judge's findings on contributory negligence sit uncomfortably with his reasons for increasing the allowance for vicissitudes to 30 percent.
