Insurance Australia Ltd trading as NRMA Insurance v Cahill

In this case, the plaintiff, Insurance Australia Ltd trading as NRMA Insurance, brought proceedings against the defendant, Cahill, regarding a motor vehicle accident. The dispute centred on the assessment of permanent impairment carried out by a review panel. The case was heard in the Supreme Court of New South Wales. The plaintiff sought judicial review of the decision made by the review panel, arguing that the panel had erred in its assessment of permanent impairment by considering an injury that had not been identified by the parties or in the material before the panel. Additionally, the plaintiff contended that the review panel had denied procedural fairness and failed to provide adequate reasons for its decision, leading to an error of law on the face of the record and a jurisdictional error.

The court was tasked with determining whether the review panel's decision contained a jurisdictional error and whether the plaintiff had been denied procedural fairness. Specifically, the court had to consider whether the panel's assessment of permanent impairment based on an unidentified injury constituted a jurisdictional error and whether the lack of adequate reasons and procedural fairness amounted to a reviewable error. The court also needed to evaluate whether the errors were apparent on the face of the record, potentially warranting the setting aside of the panel's decision.

In addressing these issues, the court found that the review panel had indeed erred by assessing permanent impairment on the basis of an injury that was not identified by the parties or in the material before the panel. The court held that this constituted a jurisdictional error, as the panel had exceeded its authority by considering an injury not properly before it. Furthermore, the court determined that the review panel had denied procedural fairness by not providing adequate reasons for its decision. The court concluded that these errors were apparent on the face of the record, leading to the decision being set aside. The court's ruling emphasised the importance of procedural fairness and the necessity for adequate reasons in administrative decisions. The court set aside the decision of the review panel and remitted the matter back to the panel for reconsideration in accordance with the law.
