Sadler v Government Insurance Office of New South Wales Government Insurance Office of New South Wales v Wallin

The case involved two separate appeals heard together in the Supreme Court of New South Wales Court of Appeal. The first appeal, *Sadler v Government Insurance Office of New South Wales*, concerned a claim for damages for personal injury. The second appeal, *Government Insurance Office of New South Wales v Wallin*, also concerned a claim for damages for personal injury. Both appeals were brought by the Government Insurance Office of New South Wales (GIO) against decisions made in favour of the respective respondents, Sadler and Wallin.

The primary legal issue before the Court of Appeal was whether the trial judges had erred in their assessment of the respondents' entitlements to damages, specifically concerning the calculation of future economic loss. The court was required to consider the principles governing the assessment of damages for loss of earning capacity, including the appropriate discount rate to be applied to future losses and the extent to which pre-existing conditions should be taken into account.

In its reasoning, the Court of Appeal applied established principles of tort law and damages assessment. The court affirmed that when assessing future economic loss, a discount rate should be applied to reflect the present value of future earnings. The court also considered the impact of the respondents' pre-existing conditions on their earning capacity, noting that damages should compensate for the loss of earning capacity caused by the injury, not for the pre-existing condition itself. The court found that the trial judges had made errors in their calculations of future economic loss, particularly in relation to the discount rate and the apportionment of loss attributable to the injury.

The Court of Appeal allowed the appeals in part, setting aside the original judgments and remitting the matters back to the trial courts for reassessment of damages in accordance with the principles laid down by the Court of Appeal.
