Government Insurance Office of New South Wales v Wolska-Gromek

The Government Insurance Office of New South Wales (GIO) appealed to the New South Wales Court of Appeal against a decision of the District Court of New South Wales. The appeal concerned a claim for damages for personal injuries sustained by the respondent, Ms. Wolska-Gromek, in a motor vehicle accident. The primary dispute revolved around the assessment of damages, specifically the extent to which the respondent's pre-existing conditions should be taken into account when calculating her loss.

The central legal issue before the Court of Appeal was whether the District Court judge had erred in law by failing to adequately consider the impact of the respondent's pre-existing degenerative spinal condition on her earning capacity and the extent of her loss flowing from the accident. The court was required to determine the correct approach to assessing damages for personal injury where a plaintiff suffers from a pre-existing condition that is aggravated or exacerbated by the injury sustained in the accident.

The Court of Appeal held that the District Court judge had made an error in his assessment of damages. The court applied the principle that where a plaintiff suffers from a pre-existing condition, the defendant is only liable for the aggravation or exacerbation of that condition caused by the defendant's negligence. The judge had failed to properly distinguish between the loss caused by the accident itself and the loss attributable to the pre-existing condition. The court found that the judge had effectively awarded damages for the entire loss of earning capacity, without sufficiently accounting for the fact that a significant portion of that loss would have been present irrespective of the accident.

Consequently, the Court of Appeal allowed the appeal, set aside the judgment of the District Court, and remitted the matter back to the District Court for a re-assessment of damages in accordance with the principles enunciated by the Court of Appeal.
