Military Rehabilitation and Compensation Commission v May

The High Court of Australia considered the appeal by the Military Rehabilitation and Compensation Commission (MRCC) against a decision of the Full Federal Court, which had overturned a decision of a single judge of that court. The dispute concerned the entitlement of Mr. May, a former member of the Australian Defence Force, to compensation under the *Military Rehabilitation and Compensation Act 2004* (Cth) (the Act) for a condition he alleged arose from his service. Mr. May had been diagnosed with a form of cancer, and the central issue was whether this condition was a "disease" for the purposes of the Act, and if so, whether it was one for which compensation was payable.

The High Court was required to determine whether the Full Federal Court had erred in its interpretation of the Act, specifically concerning the definition of "disease" and the conditions under which compensation could be awarded for such a disease. The primary legal question revolved around whether Mr. May's cancer constituted a "disease" within the meaning of the Act, and if it did, whether the MRCC had correctly applied the statutory provisions regarding the assessment and payment of compensation for such conditions. This involved an examination of the relationship between the onset of the condition and Mr. May's military service.

The Court reasoned that the term "disease" in the Act should be interpreted broadly to encompass any pathological condition that impairs the normal functioning of the body. It held that the Full Federal Court had correctly identified Mr. May's cancer as a disease for the purposes of the Act. Furthermore, the High Court affirmed that the Act provided for compensation for diseases that arose out of, or were aggravated by, service, and that the evidence supported a finding that Mr. May's cancer met this criterion. The Court emphasised that the statutory scheme was designed to provide a comprehensive safety net for veterans, and that a restrictive interpretation of "disease" would undermine this purpose.

The High Court dismissed the appeal, upholding the decision of the Full Federal Court. Consequently, Mr. May was entitled to compensation under the *Military Rehabilitation and Compensation Act 2004* (Cth) for his cancer.
