Luxotica Retail Australia Pty Ltd v Susak

The case of Luxotica Retail Australia Pty Ltd v Susak involves an appeal by the employer against a decision of an arbitrator who had determined the worker's entitlement to weekly compensation under the Workers Compensation Act 1987 (NSW) as it stood prior to amendments introduced in 2012. The worker, Mr. Susak, suffered a previous injury that resulted in partial incapacity and subsequently suffered a second injury which exacerbated his condition. The dispute centred on the calculation of Mr. Susak's ability to earn income and the extent to which his subsequent injury affected his capacity to work. The Court of Appeal was tasked with determining whether the arbitrator had correctly exercised their discretion in assessing the appropriate amount of weekly compensation, and whether the arbitrator had properly considered and applied relevant principles and evidence.

The legal issues that the court needed to resolve included whether the arbitrator had correctly interpreted and applied the principles set out in Hancock v East Coast Timber Products Pty Ltd and Paric v John Holland in determining the worker's entitlement to compensation. Additionally, the court had to consider whether the arbitrator had adequately assessed the medical evidence presented and whether the employer's arguments, which were not raised during the arbitration, could be considered. The court also examined whether the principles in University of Wollongong v Metwally and Brambles Industries Ltd v Bell were appropriately applied and whether the arbitrator's decision was adequately reasoned.

In its judgment, the Court of Appeal found that the arbitrator had correctly exercised their discretion and had properly applied the relevant legal principles in determining Mr. Susak's entitlement to weekly compensation. The court concluded that the arbitrator had appropriately assessed the medical evidence and that the employer's arguments, raised for the first time on appeal, were not to be considered. The court further found that the arbitrator's determination was adequately reasoned and did not constitute a failure to give reasons. Consequently, the court confirmed the arbitrator's determination with a minor amendment to the date in the certificate, and ordered the employer to pay the worker's costs of the appeal.
