Bradshaw v Tasmania Networks Pty Ltd

In *Bradshaw v Tasmania Networks Pty Ltd*, the Full Court of the Supreme Court of Tasmania considered an appeal concerning a workers compensation claim. The dispute involved an employee who alleged their injury was an aggravation or acceleration of a pre-existing disease, with the employer, Tasmania Networks Pty Ltd, disputing liability for weekly payments and other benefits. The matter had been referred by the employer to a tribunal, which initially found the employer had a reasonably arguable case. A primary judge on appeal subsequently found an error of law in the tribunal's decision but ultimately made the same determination.

The central legal issue before the Full Court was whether the primary judge erred in upholding the tribunal's finding that the employer had a reasonably arguable case, despite identifying an error of law. This required the court to consider the evidence regarding causation, specifically whether the injury was attributable to the employment or the natural progression of an underlying disease. The court had to determine if the evidence presented left open the possibility that the progression of the pre-existing disease was a contributing factor to the employee's condition, and if this possibility meant the employer's case was reasonably arguable.

The Full Court reasoned that the evidence presented did indeed leave open the possibility that the progression of the underlying disease was a contributing factor to the employee's current condition, separate from any aggravation caused by employment. This uncertainty meant that the employer's contention that the injury was not solely or primarily caused by their actions, but rather by the natural progression of a pre-existing condition, was a reasonably arguable position. Consequently, the Full Court concluded that the primary judge's determination, that the employer had a reasonably arguable case and that their decision was not shown to be wrong, was correct.
