Rahman v Insurance Australia Ltd t/as NRMA Insurance

The plaintiff, Mr Rahman, sought damages for psychiatric injuries sustained in a motor accident, claiming compensation under the Motor Accident Act. Insurance Australia Ltd, trading as NRMA Insurance, disputed the claim, engaging a medical assessor to review Mr Rahman's evidence. The Administrative Appeals Tribunal (AAT) was called upon to determine whether the assessor's findings were correct and if the assessment process was fair. The court's task was to decide whether the medical assessor's approach to the evidence was proper, whether the process was fair, and if the medical assessment was in error.

The primary legal issues were whether the medical assessor was biased or prejudged Mr Rahman's case, if the assessor considered irrelevant evidence or failed to consider relevant evidence, and whether the internal review process was correctly followed. The court had to assess if the AAT was correct in upholding the medical assessment and whether the AAT properly exercised its discretion in refusing to order a review of the medical assessment certificate.

The AAT found that the medical assessor did not form a preliminary view of the case but formed a firm opinion after reviewing the materials. It determined that the assessor did not prejudge or show bias, as Mr Rahman was given the opportunity to address inconsistencies in his evidence. The court concluded that the medical assessor could disregard or assign little weight to evidence based on their expertise. The AAT also found that the internal review process was correctly followed, and there was no error in material respect in the medical assessment. The AAT's discretion to refuse a review of the medical assessment certificate was upheld as it was not demonstrated that the internal review on available grounds had been sought.

The AAT's decision was affirmed, and Mr Rahman's appeal was dismissed. The court held that the AAT correctly found no error in the medical assessment and that the internal review process was correctly followed. The AAT's discretion in refusing to order a review of the medical assessment certificate was upheld, and no further relief was granted to Mr Rahman.
