Covington-Thomas v Commonwealth of Australia

Covington-Thomas brought a claim against the Commonwealth of Australia for damages resulting from the Melbourne/Voyager collision, in which the plaintiff was injured. The Commonwealth admitted negligence but contested the extent of the damages, particularly those related to the plaintiff’s post-traumatic stress disorder (PTSD) and alcoholism, as well as the costs of treatment for alcoholism. The central issue for the court was to determine the causation of the plaintiff's PTSD and alcoholism in relation to the collision, and the admissibility of certain medical expenses for treatment of alcoholism, as well as the impact on the plaintiff’s future career prospects within the Navy.

The court examined the evidence regarding the onset and progression of the plaintiff's PTSD and alcoholism, assessing whether these conditions were a direct consequence of the collision. It considered the expert testimony and medical reports to establish a causal link between the collision and the plaintiff's mental health issues and alcoholism. Additionally, the court deliberated on the necessity and reasonableness of the expenses incurred for alcoholism treatment, taking into account the plaintiff's future career aspirations within the Navy. The court applied principles of causation and the foreseeability of the injuries to determine the extent of the damages recoverable.

The court concluded that the plaintiff's PTSD and alcoholism were directly caused by the collision, thereby accepting the admissibility of the related medical expenses. However, the court exercised its discretion to discount the damages to reflect the probabilities of the plaintiff’s future career in the Navy, considering the inherent vicissitudes of such a career path. The court awarded damages that balanced the plaintiff's need for rehabilitation against the realistic prospects of continued employment in the Navy.

The final orders included a determination of the total damages recoverable, reflecting the court’s assessment of the plaintiff's condition, treatment costs, and the discount applied for future career prospects. The court ordered the Commonwealth to pay the plaintiff the calculated damages, taking into account the admitted negligence and the specific issues of causation and recovery of expenses.
