Tanks v Workcover

The High Court of Australia considered an appeal by WorkCover Queensland (WorkCover) against a decision of the Queensland Court of Appeal, which had overturned a decision of the Queensland Industrial Relations Commission. The dispute concerned the eligibility of Mr Mark Tanks to receive workers' compensation benefits for a psychiatric injury allegedly sustained during his employment as a police officer. WorkCover had denied his claim, and this denial was upheld by the Commission, but subsequently overturned by the Court of Appeal.

The central legal issue before the High Court was whether Mr Tanks' psychiatric injury was an "injury" for the purposes of the *Workers' Compensation and Rehabilitation Act 2003* (Qld) (the Act). Specifically, the Court had to determine whether the injury arose out of or in the course of his employment, and whether it was a "personal injury" as defined by the Act, which includes a "disease contracted or injury sustained". The Court also considered the application of section 11A of the Act, which excludes compensation for psychiatric injury if it is a consequence of reasonable management action taken in a reasonable way by the employer.

The High Court, by majority, allowed the appeal and set aside the order of the Queensland Court of Appeal. The majority held that the Court of Appeal had erred in its interpretation of the Act. They found that the evidence did not establish that Mr Tanks' psychiatric condition was a "disease contracted" or an "injury sustained" in the course of his employment. Furthermore, the majority concluded that even if a psychiatric injury was established, it was a consequence of reasonable management action taken in a reasonable way, and therefore excluded from compensation under section 11A of the Act. The Court emphasised that the onus was on the worker to prove that the injury was not a consequence of reasonable management action.

The High Court ordered that the appeal be allowed, the orders of the Queensland Court of Appeal be set aside, and that the decision of the Queensland Industrial Relations Commission be restored.
