Buestami v Allianz Australia Finance Ltd

The plaintiff, Buestami, sought judicial review of decisions made by a medical assessor and a delegate of the President of the Personal Injury Commission under the Motor Accidents Compensation Act 1999 (NSW). The plaintiff contested the determination of his whole person impairment (WPI) following a motor accident. The dispute centred on the Review Panel's issuance of a medical assessment certificate that set the plaintiff's WPI at 8% without considering the impairment from a subsequent injury or conducting the required calculation. The matter was heard in the Supreme Court of New South Wales.

The court was tasked with determining whether the Review Panel properly exercised its jurisdiction under the Act, particularly in failing to account for the plaintiff's impairment from a subsequent injury and in not conducting the appropriate calculation. The plaintiff argued that the Review Panel's decision was flawed due to these omissions, which rendered the medical assessment and review determination invalid. The court needed to assess whether these errors were significant enough to set aside the decision and remit the matter for re-determination.

The court found that the Review Panel had indeed failed to exercise its jurisdiction as required by the Act. It did not properly determine the extent of the plaintiff's WPI as it existed at the time of assessment, nor did it consider the impairment from a subsequent injury or conduct the necessary calculation. These errors meant that the Review Panel's decision was flawed and did not meet the legal standards set by the Act. Consequently, the court set aside the medical assessment and review determination, and the matter was remitted for re-determination by a properly constituted Review Panel.

No further orders were made beyond the remittal of the matter for re-determination. The court emphasised the importance of the Review Panel adhering to the statutory requirements when making determinations regarding WPI and the need for a thorough and legally sound assessment process.
