City of Melbourne v Neppessen

City of Melbourne brought a judicial review application against the decision of a medical panel appointed by the City to assess the impairment caused by an ankle injury sustained by the respondent, Neppessen. The Supreme Court of Victoria was asked to determine whether the panel had erred in their assessment by misapplying the American Medical Association Guides to the Assessment of Permanent Impairment (Fourth Edition). The central issue before the court was whether the panel's decision was so flawed as to constitute a jurisdictional error or a legal unreasonableness that would warrant setting aside the decision.

The court found that the panel had indeed applied the AMA Guides incorrectly by not considering certain factors that were relevant to the assessment of the impairment. However, the court held that this error did not amount to a jurisdictional error or legal unreasonableness sufficient to invalidate the panel's decision. The court reasoned that the panel's error was not so significant as to undermine the entire decision, and that the assessment of impairment involved a degree of medical judgment and discretion that was not subject to strict legal standards.

Consequently, the court dismissed the application for judicial review. The court held that the panel's decision was not so flawed as to warrant intervention by the court, and that the assessment of impairment was ultimately a matter for the medical experts appointed by the parties. The court also noted that the applicant had not demonstrated that the panel's error had resulted in a significant injustice or unfairness to the respondent. Therefore, the decision of the panel was upheld, and the respondent's impairment assessment remained as determined by the panel.
