Fahey v Government Insurance Office of New South Wales

The New South Wales Court of Appeal heard an appeal concerning a claim for damages for personal injury. The appellant, Mr Fahey, had suffered injuries in a motor vehicle accident and sought to recover damages from the respondent, the Government Insurance Office of New South Wales (GIO), which was the compulsory third party insurer. The primary dispute revolved around the assessment of the appellant's damages, specifically the extent to which his pre-existing conditions should be taken into account when calculating the compensation payable for the injuries sustained in the accident.

The central legal issue before the Court of Appeal was whether the GIO was entitled to reduce the damages awarded to Mr Fahey by reason of his pre-existing degenerative back condition. The appellant argued that the damages should be assessed based on the aggravation of his pre-existing condition caused by the accident, rather than a reduction for the condition itself. The GIO contended that the pre-existing condition was a significant factor that diminished the extent to which the accident had caused the appellant's current incapacity and therefore should be reflected in a lower damages award.

The Court of Appeal, applying established principles of tortious liability and damages assessment, held that the correct approach was to assess the damages by reference to the *aggravation* of the pre-existing condition caused by the accident. The court affirmed that an insurer is liable for the consequences of the injury caused by the accident, even if those consequences are more severe due to a pre-existing vulnerability. However, the court also acknowledged that the pre-existing condition could be relevant in determining the *extent* of the aggravation and the appellant's overall loss. The court found that the trial judge had erred in failing to adequately consider the extent to which the accident had aggravated the pre-existing condition.

The Court of Appeal allowed the appeal, setting aside the original judgment and remitting the matter back to the Supreme Court for a redetermination of the damages assessment in accordance with the principles outlined in the judgment.
