Insurance Australia Group Limited t/as NRMA Insurance v Saraceni

In the case of Insurance Australia Group Limited trading as NRMA Insurance v Saraceni, the matter was heard in the New South Wales Supreme Court. The primary dispute centred around the assessment of permanent impairment following a motor vehicle accident, and whether the decision of a medical review panel was legally sound. The panel had concluded that the appellant, Mr Saraceni, was entitled to a certain level of compensation based on the Motor Accident Permanent Impairment Guidelines. NRMA Insurance, the respondent, challenged this decision, arguing that the panel had not adhered to the guidelines, and thus, the decision was flawed.

The court was tasked with determining several key legal issues. These included whether the medical review panel had failed to set out lawful reasons for its determination, whether the decision was vitiated by legal unreasonableness, and whether the inconsistencies in the medical assessments amounted to a jurisdictional error. Furthermore, the court had to assess whether the panel's failure to provide procedural fairness to the parties involved rendered the decision invalid. The central concern was whether the inconsistencies in the medical assessments, which were not brought to the attention of the first defendant, were material and whether they violated the guidelines in a way that rendered the decision unlawful.

The court found that the medical review panel had indeed erred by not adhering to the Motor Accident Permanent Impairment Guidelines. While the inconsistencies were contemplated by the guidelines, the panel had not provided reasons for their determination that aligned with the statutory requirements. The court held that the panel's failure to address these inconsistencies amounted to a breach of the duty to provide procedural fairness. This failure was deemed material, and the court concluded that the decision was vitiated by legal unreasonableness. The court further held that the inconsistencies amounted to a jurisdictional error, resulting in a constructive failure to exercise jurisdiction. Consequently, the appeal was upheld, and the decision of the medical review panel was quashed. The court also determined that the costs of the appeal would follow the event, and Mr Saraceni was granted an indemnity certificate under the Suitors' Fund Act 1951, making him eligible for costs.
