Coffey v Secretary, Department of Social Security

The case of *Coffey v Secretary, Department of Social Security* concerned an appeal to the Full Federal Court of Australia. The appellant, Mr. Coffey, sought to challenge a decision made by the respondent, the Secretary of the Department of Social Security, which had affirmed a determination that he was not entitled to a disability support pension. The dispute centred on whether Mr. Coffey's medical condition constituted a "severe disability" for the purposes of the *Social Security Act 1991* (Cth).

The primary legal issue before the Full Federal Court was whether the Administrative Appeals Tribunal (AAT) had erred in law in its assessment of Mr. Coffey's eligibility for a disability support pension. Specifically, the court was required to consider whether the AAT had correctly applied the relevant provisions of the *Social Security Act 1991* (Cth) and associated legislative instruments in determining whether Mr. Coffey's impairments resulted in a level of incapacity that met the statutory threshold for a severe disability. This involved an examination of the criteria for assessing functional capacity and the impact of Mr. Coffey's conditions on his ability to work.

The court, comprising Kirby and Callinan JJ, ultimately found that the AAT had made an error of law. Their Honours reasoned that the Tribunal had failed to adequately consider the cumulative effect of Mr. Coffey's various impairments and their combined impact on his capacity to undertake work. The judges emphasised that the assessment of a "severe disability" required a holistic approach, taking into account all relevant medical conditions and their synergistic effects, rather than treating each impairment in isolation. The appeal was allowed, and the matter was remitted to the AAT for redetermination according to law.
