Gleeson v Government Insurance Office of New South Wales

In *Gleeson v Government Insurance Office of New South Wales* [1994] NSWCA 109, the New South Wales Court of Appeal considered an appeal concerning the assessment of damages for a motor vehicle accident. The appellant, Mr Gleeson, had suffered injuries in a motor vehicle accident and sought to recover damages from the respondent, the Government Insurance Office of New South Wales, which was the compulsory third party insurer. The core of the dispute revolved around the appropriate method for calculating the appellant's loss of earning capacity.

The primary legal issue before the Court of Appeal was whether the trial judge had erred in their assessment of the appellant's future economic loss. Specifically, the court had to determine if the method used to discount future economic loss to its present value was appropriate, and whether the assumptions made regarding the appellant's future earning potential and the duration of his incapacity were sound. The court also considered the impact of the appellant's pre-existing conditions on his earning capacity.

The Court of Appeal, in its reasoning, affirmed the principles governing the assessment of economic loss in personal injury cases. It reiterated that the assessment of future economic loss requires a degree of speculation, but this speculation must be grounded in evidence and guided by established legal principles. The court examined the trial judge's approach to discounting, noting that while a precise formula is not always mandated, the discount rate applied should reflect a realistic consideration of investment returns and inflation. Furthermore, the court emphasised that when assessing loss of earning capacity, the court must consider not only the direct impact of the injury but also any pre-existing vulnerabilities that might exacerbate the loss. The court found that the trial judge had made a number of errors in the calculation of the appellant's economic loss, particularly in relation to the discount rate and the assessment of the appellant's capacity to mitigate his loss.

The Court of Appeal allowed the appeal, setting aside the original judgment and remitting the matter back to the trial court for a re-assessment of damages in accordance with the principles articulated by the Court of Appeal.
