Usher v Coffs Harbour City Council

Usher was a council employee who suffered a work-related injury. The council accepted liability for the injury but disputed the extent of compensation payable. The dispute was brought before the Workers Compensation Court of New South Wales. The central legal issues were whether the council had adequately demonstrated that the injury materially contributed to the need for surgery and the extent to which the council was liable for compensation.

The court examined the principles applicable to disturbing a primary decision maker's factual determination, drawing on cases such as Branir Pty Ltd v Owston Nominees (No 2) Pty Ltd, Raulston v Toll Pty Ltd, and Najdovski v Crnojlovic. The court considered the causation principles from Kooragang Cement Pty Ltd v Bates and applied Murphy v Allity Management Services Pty Ltd in assessing whether the injury materially contributed to the need for surgery. The court held that the council had not sufficiently demonstrated that the injury materially contributed to the need for surgery. Consequently, the council's liability for compensation was limited to the injury without the additional costs for surgery.

The Workers Compensation Court ruled in favor of Usher, determining that the council's liability was limited to the original injury and not the surgery. The court did not award additional compensation for the surgery, as the council had not met the burden of proving that the injury materially contributed to the need for the surgical procedure. The final order was that the council was liable for compensation based solely on the original injury.
