NACD v MIMIA

The applicants, NACD, sought judicial review of a decision made by the respondent, MIMIA, concerning the applicant's eligibility for a disability support pension. The dispute centred on whether NACD met the criteria for permanent incapacity for work, a key requirement for receiving the pension. The matter was heard by Gummow and Heydon JJ of the High Court of Australia.

The central legal issue before the High Court was the proper interpretation and application of the legislative provisions governing permanent incapacity for work under the *Social Security Act 1991* (Cth). Specifically, the court had to determine whether the assessment of NACD's capacity to work had been conducted in accordance with the statutory framework, particularly concerning the consideration of all relevant factors, including the applicant's age, education, and work history, in conjunction with medical evidence.

Gummow and Heydon JJ reasoned that the assessment of permanent incapacity required a holistic approach, considering not only medical conditions but also the practical employability of the individual. They emphasised that the legislative test was not solely about the existence of a medical impairment but about the functional capacity to engage in any form of substantial gainful employment. The court found that the delegate had failed to adequately consider the cumulative effect of NACD's impairments and their impact on his ability to obtain and maintain employment, thereby misinterpreting the statutory test for permanent incapacity.

The High Court allowed the appeal, quashed the decision of MIMIA, and remitted the matter to the Administrative Appeals Tribunal for redetermination according to law.
