Pinarbasi v AAI Ltd t/as GIO

In Pinarbasi v AAI Ltd t/as GIO, the dispute centred around a motor vehicle accident claim under the Motor Accidents Injuries Act 2017 (NSW). Pinarbasi, the claimant, had filed a claim for compensation after an accident. The insurer, AAI Limited trading as GIO, rejected the claim. The claimant sought review of this decision, and a medical assessor concluded that Pinarbasi's shoulder injury was not minor. The insurer then applied for a review of the assessor's certificate. The case reached the court as it involved the President of the Personal Injury Commission of NSW exercising a gateway function under section 7.26(5) of the Act to decide whether there was reasonable cause to suspect a material error in the medical assessment. The President referred the review application to a review panel, a decision which Pinarbasi challenged.

The primary legal issues the court had to decide were whether the President's gateway function was administrative in nature, and if so, whether there was an implied obligation for the President to give reasons for the decision to refer the case to the review panel. Additionally, the court had to determine if the President's decision to refer the case to the review panel constituted a jurisdictional error, particularly in relation to whether the President had considered the statutory criteria correctly.

The court found that the President's gateway function was indeed of an administrative character, thus subject to judicial review. However, it held that there was no implied obligation for the President to provide reasons for their decision to refer the case to a review panel. The court further ruled that the President's decision to refer the case constituted a jurisdictional error. This was based on the President's failure to consider whether there was reasonable cause to suspect a material error in the medical assessment, particularly when the medical assessor had not accepted the medical opinions relied upon by the insurer. The court concluded that the President's decision to refer the matter to a review panel was erroneous and quashed the decision.

The final orders of the court quashed the decision of the President to refer the case to the review panel, thereby invalidating the referral and leaving the initial assessment by the medical assessor as the determination of the case.
