Mackenzie v Allianz Australia Insurance Ltd (No. 2)

The plaintiffs in the matter, Mackenzie, sought judicial review of a decision made by the Motor Accidents Authority Review Panel. The dispute centred on whether the Review Panel had erred in law or made a jurisdictional error in its decision. The court was asked to determine whether the Review Panel had failed to fulfil its obligation to conduct a proper examination of the evidence before it. The plaintiffs also argued that the examination conducted by two of the three assessors who comprised the Review Panel was invalid under section 63 of the Motor Accidents Compensation Act 1999 (NSW).

The court considered whether there was any error of law or jurisdictional error established in the Review Panel's decision. The plaintiffs argued that the Review Panel had failed to properly consider the evidence before it, and that the examination conducted by two of the three assessors was invalid. The court considered the doctrine of stare decisis, and noted that there was an earlier Supreme Court decision which had found that there was no error of law or jurisdictional error in a similar case. The court found that there was no reason to depart from that earlier decision.

The court dismissed the summons, finding that there was no basis to conclude that the Review Panel had failed to fulfil its obligation to conduct a proper examination of the evidence before it. The court found that there was no error of law or jurisdictional error established in the Review Panel's decision, and that the examination conducted by two of the three assessors was valid under section 63 of the Motor Accidents Compensation Act 1999 (NSW). The court noted that the plaintiffs had not established any grounds for setting aside the Review Panel's decision.

The court dismissed the summons and made no orders for costs.
