Merhi v Insurance Australia Limited t/as NRMA Insurance

The case of Merhi v Insurance Australia Limited t/as NRMA Insurance involved a dispute over whether the plaintiff's injury following a motor accident constituted a 'threshold injury' under the Motor Accident Injuries Act 2017 (MAI Act). The matter was heard in the District Court of New South Wales. The plaintiff argued that radiculopathy, a nerve root injury, was present, and thus his injury met the threshold criteria for compensation. Conversely, the defendant insurer maintained that the plaintiff did not suffer from radiculopathy and therefore the injury was not a threshold injury.

The legal issues central to the case revolved around the interpretation and application of section 7.26(6A) of the MAI Act, specifically whether the presence of radiculopathy could be established through any medical assessment following the accident. The court had to determine whether the assessment by the Medical Review Panel was the definitive assessment or if other medical assessments were also pertinent. The case hinged on the understanding of the role of the Medical Review Panel and the timing and nature of medical assessments required under the Motor Accident Guidelines.

In its reasoning, the court held that the Motor Accident Guidelines and the MAI Act established a scheme whereby the Medical Review Panel's assessment ultimately determines the presence of a threshold injury. The court emphasised that the critical assessment is conducted by the Medical Review Panel medical assessors during their re-examination of the plaintiff. The court found that the Medical Review Panel's assessment did not identify radiculopathy, and thus the injury did not meet the threshold criteria. Consequently, the plaintiff's claim for compensation was denied.

The court ordered that the Medical Assessment Certificate confirming the absence of radiculopathy was upheld and that the injury was not a threshold injury under the MAI Act.
