St Mary Star of the Sea College v Watt

The appeal concerned a negligence claim brought by a student, Ms Watt, against St Mary Star of the Sea College. Ms Watt alleged she suffered injury during a gymnastic activity conducted at the school due to the negligent supervision of her teacher. The primary dispute revolved around whether the teacher had breached their duty of care to Ms Watt and, if so, whether that breach had caused her injuries. The matter was heard on appeal before the New South Wales Court of Appeal.

The Court of Appeal was required to determine whether the trial judge had erred in finding that the teacher's conduct constituted a breach of the duty of care owed to Ms Watt. Further, the court had to consider whether the trial judge had correctly concluded that any such breach was causative of the harm suffered by Ms Watt. A significant aspect of the appeal involved reviewing the trial judge's assessment of the credibility of Ms Watt and the witnesses called by the college, including the trial judge's observations regarding their demeanour.

The appellate court affirmed the trial judge's findings, giving considerable weight to the trial judge's superior position to assess the credibility of witnesses. The court applied established principles of negligence, focusing on the standard of care expected of a teacher in supervising students during physical activities. The reasoning underscored that an appellate court should be slow to overturn a trial judge's findings of fact, particularly those based on an assessment of witness demeanour, unless there is a clear and compelling reason to do so. The appeal was dismissed, and the college was ordered to pay the costs of the appeal.
