Winchester and Comcare (Compensation)

This matter concerned an appeal by an applicant against a decision of the Administrative Appeals Tribunal affirming a decision regarding compensation for permanent impairment and non-economic loss. The applicant had originally suffered a psychiatric injury in the early 1990s while employed by the Aboriginal and Torres Strait Islander Commission (ATSIC). The core dispute revolved around whether the applicant continued to suffer from this accepted psychiatric condition, or if subsequent events had displaced it as the material cause of his present difficulties, potentially leading to a new condition such as adjustment disorder.

The court was required to determine whether the applicant continued to suffer from accepted conditions, or if he now suffered from conditions not materially contributed to by his work. If the former, the court needed to ascertain if these accepted conditions continued to be materially contributed to by his former employment with ATSIC, such that he still had a disease for the purposes of the relevant Act. Further issues concerning permanent impairment and non-economic loss were contingent on these primary determinations.

The court found that there was significant doubt as to whether the applicant's current difficulties could be materially attributed to the ATSIC employment, which occurred 20-25 years prior. It reasoned that other documented factors, including a cerebellar stroke in 2012, a malignancy diagnosed and treated in 2015, and self-reported anxiety about financial pressures, had displaced the initial workplace incident. Consequently, even if the ATSIC employment had contributed to the applicant's present condition, it could no longer be said to be the material cause. The court concluded that the applicant no longer suffered from an injury or disease that met the requirements of sections 24 or 27 of the Act. The reviewable decision of the Tribunal was affirmed.
