Horne and Comcare (Compensation)

The Administrative Appeals Tribunal considered a claim for workers' compensation by the applicant, Mr. Horne, against Comcare. Mr. Horne sought compensation for a psychological condition and an impotency condition, alleging these arose from a previously accepted workers' compensation claim for a back injury. The central dispute was whether these subsequent conditions could be classified as injuries or diseases under the relevant Act and whether Mr. Horne's employment contributed to them to a significant degree.

The Tribunal was required to determine if the applicant's psychological condition and impotency condition qualified as compensable injuries or diseases under the *Safety, Rehabilitation and Compensation Act 1988* (Cth). Specifically, the Tribunal had to assess whether the applicant's employment contributed to these conditions to a "significant degree," which is defined by the Act as substantially more than material. The applicant relied on section 5A(1)(a) for his psychiatric condition and section 5A(1)(b) for his impotency condition.

The Tribunal considered evidence from the applicant and an independent psychiatrist, Associate Professor Sahoo. While Dr. Sahoo initially diagnosed a "major depressive disorder, moderate depression, due to a medical condition which is the back injuries and the pain associated with it," he later revised this diagnosis to remove the reference to a "general medical condition," acknowledging the influence of the applicant's diabetes. However, Dr. Sahoo maintained his opinion regarding causation, confirming that the applicant experienced irritable depression and had lost interest in daily activities. Despite this, the Tribunal ultimately found that the applicant's psychological condition and impotency condition were not related to his back injury.

The Tribunal affirmed the decisions under review dated 1 August 2016 and 22 February 2017, meaning Comcare's previous decisions to deny compensation for the psychological and impotency conditions were upheld.
