ICI Australia Operations Pty Ltd v Workcover Authority of New South Wales

The appeal concerned the interpretation of provisions within the *Workers Compensation Act 1987* (NSW) relating to dust diseases and the role of the WorkCover Authority of New South Wales. The primary dispute involved whether WorkCover was liable to indemnify ICI Australia Operations Pty Ltd (now Orica Australia Pty Ltd) for damages and costs paid to a worker, George Roland Brazier, who suffered a dust-related disease. The case was heard by Mason P, Meagher and McColl JJA.

The central legal issues before the court were: first, the meaning of "employment to the nature of which the disease was due" in the context of section 151AB of the Act, and whether this required consideration of the specific occupational disease suffered by the worker; second, the standard of proof applicable in such claims; third, the extent to which judges of the Dust Diseases Tribunal could rely on their specialised knowledge; and fourth, whether section 232 of the Act conferred a discretion on WorkCover to make payments from the Insurers' Guarantee Fund, particularly where an employer's liability had been discharged by a designated insurer. The court also considered the effect of an undertaking given by WorkCover to the Dust Diseases Tribunal regarding reimbursement of the employer.

The Court of Appeal allowed the appeal, holding that WorkCover was liable to indemnify ICI Australia Operations Pty Limited. The reasoning focused on the interpretation of section 232, finding that it did not confer an unfettered discretion but rather imposed a liability on WorkCover to reimburse an employer where the employer had been found liable for a dust disease. The court determined that the undertaking given by WorkCover to the Tribunal was significant and that the Authority had the power to reimburse the employer even though the employer's liability had been discharged by a designated insurer. The cross-appeal was dismissed.
