Badawi v Nexon Asia Pacific Pty Ltd

The appeal concerned the entitlement to workers' compensation for an injury sustained by the appellant, Mr. Badawi, in the course of his employment with the respondent, Nexon Asia Pacific Pty Ltd. The dispute centred on whether Mr. Badawi's employment was a substantial contributing factor to his injury, as required by section 9A of the *Workers Compensation Act 1987* (NSW). The matter came before the Court of Appeal of New South Wales following a decision of the Workers Compensation Commission.

The primary legal issue before the Court of Appeal was whether the Commission had erred in law by misconstruing section 9A of the *Workers Compensation Act 1987* (NSW). Specifically, the court had to determine the correct interpretation of "substantial contributing factor" and whether the Commission had applied the correct test when assessing causation, distinguishing it from the test for an injury "arising out of employment" under section 9 of the Act. The court also considered the relevance of "the nature of the work performed and the particular tasks of that work" in this assessment.

The Court of Appeal found that the Commission had misconstrued section 9A by failing to properly apply the statutory test for a "substantial contributing factor." The court clarified that "substantial" means real or of substance, and that the assessment of whether employment was a substantial contributing factor to the injury is a separate test from whether the injury arose out of employment. The court held that the Commission had erred in law by not adequately considering the nature of the work performed and the particular tasks undertaken by Mr. Badawi in its determination of causation under section 9A. Consequently, the appeal was allowed, the decision of the Commission was set aside, and the matter was remitted to the Commission for redetermination. The respondent was ordered to pay the appellant's costs.
