JC Equipment Hire Pty Limited v The Registrar of the Workers Compensation Commission of NSW

JC Equipment Hire Pty Limited appealed to the Court of Appeal of New South Wales against a decision of an Associate Justice of the Workers Compensation Commission. The dispute concerned whether the appellant, having accepted a certain degree of whole person impairment for the purposes of a statutory lump sum compensation claim under section 66 of the *Workers Compensation Act 1987* (NSW), was estopped from denying that same degree of impairment for the purposes of a separate work injury damages claim.

The primary legal issues before the Court of Appeal were whether the acceptance of a degree of whole person impairment for a section 66 claim constituted an acceptance for a work injury damages claim, and whether the appellant was estopped by conduct from denying the degree of whole person impairment in the context of the work injury damages claim. The Court also considered the legislative history and the dichotomy between statutory compensation and common law damages in New South Wales.

The Court of Appeal allowed the appeal, setting aside the orders of the Associate Justice. It reasoned that the two types of claims, statutory compensation and work injury damages, were distinct and governed by different legislative regimes. The acceptance of impairment for one claim did not automatically bind the party in the other. The Court found that the determination by the Delegate of the Registrar that a pre-filing statement was not defective should be quashed, and the matter remitted for re-determination. The respondent was ordered to pay the costs of the appeal.
