Berrell v Allianz Australia Insurance Ltd

Berrell v Allianz Australia Insurance Ltd was a case in the Supreme Court of New South Wales that involved a dispute between the plaintiff, Berrell, and Allianz Australia Insurance Ltd, regarding the assessment of permanent impairment following a motor accident. The State Insurance Regulatory Authority had previously issued a primary medical assessment certificate stating that Berrell had no whole person impairment. Berrell sought a referral of the assessment to a review panel under section 63 of the Motor Accidents Compensation Act 1999 (NSW). However, the proper officer of the Authority had refused this request, prompting Berrell to seek judicial review of the decision.

The central legal issue in the case was whether the decision of the proper officer to refuse the referral of the medical assessment to a review panel was unreasonable. The court was required to determine if there was reasonable cause to suspect that the assessment was "incorrect in a material respect" and whether the decision lacked an "evident and intelligible justification." This hinged on whether the assessor had applied the methodology set out in the MAA Permanent Impairment Guidelines.

The court found that the proper officer's decision was not unreasonable, as there was no evidence to suggest that the assessment was incorrect in a material respect. The court held that the assessor's failure to apply the methodology in the MAA Permanent Impairment Guidelines did not render the assessment incorrect in a material respect. The decision of the proper officer was justified, as there was no evident and intelligible justification for a referral to a review panel. Consequently, the summons was dismissed.
