Warth v Lafsky

The appeal concerned a motor vehicle accident where the appellant, the driver, collided with the respondent, a child on a scooter. The primary dispute revolved around whether the appellant's driving conduct constituted negligence that caused the respondent's injuries. The matter came before the Court of Appeal of New South Wales.

The legal issues before the court included whether the appellant failed to keep a proper lookout and drove at an excessive speed, thereby breaching their duty of care to the respondent. Crucially, the court was required to determine the issue of causation, specifically whether the appellant's alleged negligence was a necessary condition for the occurrence of the harm suffered by the respondent, in accordance with section 5D of the *Civil Liability Act 2002* (NSW). This involved considering whether the accident was inevitable, irrespective of the appellant's speed or attention. The court also considered an application for leave to amend the notice of appeal made during the hearing.

The Court of Appeal granted leave to appeal but ultimately dismissed the appeal. The court found that the appellant's driving at an excessive speed and failure to keep a proper lookout constituted negligence. Applying section 5D of the *Civil Liability Act 2002* (NSW), the court determined that the appellant's negligence was a factual cause of the respondent's injuries, as the accident would not have occurred had the appellant been driving at a reasonable speed and keeping a proper lookout. The court therefore remitted the proceedings to the District Court for the assessment of damages.
