Watterson and Visionstream Pty Ltd (Compensation)

The Administrative Appeals Tribunal (AAT) considered a compensation claim brought by Mr Watterson against Visionstream Pty Ltd. Mr Watterson alleged that he had suffered an injury as a result of exposure to radiation during his employment. Visionstream denied liability, and the AAT was tasked with reviewing decisions made under the *Safety, Rehabilitation and Compensation Act 1988* (Cth).

The primary legal issue before the Tribunal was whether Mr Watterson's claimed condition arose out of, or in the course of, his employment with Visionstream. This required the Tribunal to assess the evidence presented, particularly concerning the alleged exposure to radiation and its potential causal link to any injury sustained.

The Tribunal found significant difficulty in accepting Mr Watterson's evidence without corroboration due to instances where he had provided incorrect or incomplete information to medical professionals and his employer. The Tribunal noted that injuries caused by radiation exposure are often difficult to assess objectively. Mr Watterson had pre-existing medical issues that he had not fully disclosed to medical specialists, which hindered their ability to properly analyse his condition and compare it to any problems arising after the alleged exposure. For example, he had provided conflicting medical histories to different doctors, and a pre-employment health history form indicated he had no current medical conditions, had not been treated recently, had never been hospitalised, had no time off work for illness or injury in the preceding two years, had no prior workers' compensation claims, and had never had an x-ray or scan, despite evidence to the contrary.

The Tribunal affirmed the decisions under review, indicating that Mr Watterson had not established that his claimed condition arose out of or in the course of his employment.
