Hammond Worthington v Da Silva

In Hammond Worthington v Da Silva, the plaintiff sought to recover damages from the defendant for professional negligence in failing to pursue a common law claim against the plaintiff's former employer, which was now statute-barred. The dispute also involved the quantification of the plaintiff's lost opportunity, jurisdictional issues concerning a medical assessment panel, and the aggregation of disabilities under workers' compensation legislation. The case was heard in the Supreme Court of Western Australia. The court was tasked with determining the principles applicable to assessing the value of the plaintiff's lost opportunity, the jurisdiction and binding nature of the medical assessment panel's determinations, the correct methodology for aggregating disabilities under workers' compensation legislation, and the assessment of damages for aggravation of an existing condition.

The court examined the principles governing the assessment of damages for a lost opportunity when a common law claim is statute-barred. It considered whether the loss of chance doctrine could be applied and how the value of the lost opportunity should be quantified. The court also addressed the jurisdiction of the medical assessment panel, including whether a privative clause rendered its decisions final and binding, and the proper methodology for assessing the degree of disability under workers' compensation legislation. Furthermore, the court deliberated on the applicable limitation period for tort claims and the quantification of damages for the aggravation of an existing condition.

The court concluded that the principles for assessing the value of a lost opportunity in a statute-barred claim required a pragmatic approach, considering the likelihood of success and the value of the potential recovery. It found that the medical assessment panel's determinations were indeed final and binding due to the privative clause. The court established that when multiple disabilities were present, aggregation could occur if the items in Schedule 2 of the Workers' Compensation and Rehabilitation Act 1981 (WA) were related and not separately compensable. The court also ruled that the limitation period for tort claims was applicable and provided guidance on assessing damages for the aggravation of an existing condition.

The final orders of the court included a determination on the value of the plaintiff's lost opportunity, confirmation of the binding nature of the medical assessment panel's decisions, and guidelines for the aggregation of disabilities under workers' compensation legislation. The court also clarified the methodology for assessing damages for the aggravation of an existing condition, providing a framework for future cases involving similar issues.
