QBE Insurance Limited v Switzerland Insurance Workers Compensation (NSW) Limited

QBE Insurance Limited and Switzerland Insurance Workers Compensation (NSW) Limited were parties to a dispute concerning the apportionment of liability for a worker's compensation claim. The matter came before the High Court of Australia following an appeal from the Court of Appeal of New South Wales.

The central legal issue before the High Court was the correct application of section 22 of the *Workers Compensation Act 1987* (NSW) in circumstances where a single, partial incapacity arose from a succession of injuries. Specifically, the court had to determine how to identify the "last causative injury" of that incapacity for the purpose of apportioning liability between successive insurers.

The High Court found that the Court of Appeal had failed to consider arguments raised by QBE Insurance Limited, leading to a miscarriage of justice. The court reasoned that the proper interpretation and application of section 22 required a more thorough examination of the causal link between the successive injuries and the ultimate incapacity.

Consequently, the High Court granted special leave to appeal, allowed the appeal with costs, and set aside the order of the Court of Appeal that dismissed QBE's cross-appeal. The matter was remitted to the Court of Appeal to hear and determine the cross-appeal.
