Chiropractors Ass of Aus (SA) & Anor v Workcover Corp

The Chiropractors Association of Australia (SA) and its president brought proceedings against WorkCover Corporation of South Australia. The dispute concerned the interpretation and application of provisions within the *Workers Rehabilitation and Compensation Act 1986* (SA) relating to the assessment of compensation for work-induced injuries. The matter was heard by the High Court of Australia.

The central legal issue before the High Court was whether the *Workers Rehabilitation and Compensation Act 1986* (SA) permitted the recovery of compensation for the aggravation, acceleration, or recurrence of a pre-existing condition caused by a work injury, or whether it limited compensation to injuries that were entirely new and distinct from any prior condition. This involved determining the scope of "injury" as defined by the Act and its interaction with the concept of pre-existing conditions.

The High Court reasoned that the Act's language did not require an injury to be entirely novel to be compensable. Instead, it found that the statutory framework contemplated that a work injury could manifest as the aggravation, acceleration, or recurrence of a pre-existing condition. The Court applied principles of statutory interpretation, emphasising that the purpose of workers' compensation legislation is to provide a remedy for workers who suffer harm in the course of their employment. Consequently, the Court held that compensation was available for the consequences of a work injury, even where those consequences involved a pre-existing condition.

The High Court allowed the appeal, setting aside the orders of the Full Court of the Supreme Court of South Australia. The matter was remitted to the Supreme Court for further consideration in accordance with the High Court's judgment.
