Commonwealth of Australia v Mewett- C of A v Rock- C of A v Brandon

The High Court of Australia considered appeals by the Commonwealth of Australia against decisions of the Federal Court of Australia in three separate cases: *Commonwealth v Mewett*, *Commonwealth v Rock*, and *Commonwealth v Brandon*. The central dispute in each case concerned the entitlement of certain Commonwealth employees to long service leave under the *Long Service Leave (Commonwealth Employees) Act 1976* (Cth) (the Act). The employees in question had periods of service that included time spent as members of the Australian Defence Force. The Commonwealth argued that these periods of defence service should not be counted as qualifying service for the purposes of long service leave entitlements under the Act.

The primary legal issue before the High Court was whether, and to what extent, service as a member of the Australian Defence Force constituted "service" within the meaning of the *Long Service Leave (Commonwealth Employees) Act 1976*. Specifically, the Court had to determine if the Act intended to include such defence service as qualifying service for long service leave, or if it was implicitly excluded by the nature of defence service or by other Commonwealth legislation. This involved an interpretation of the Act's provisions, including definitions of "service" and "employee," and consideration of the relationship between the Act and other legislation governing defence personnel.

The High Court, in a joint judgment, held that service as a member of the Australian Defence Force did not constitute "service" for the purposes of the *Long Service Leave (Commonwealth Employees) Act 1976*. The Court reasoned that the Act was intended to apply to civilian employment within the Commonwealth service and that the specific nature of military service, including its distinct conditions and entitlements, meant it fell outside the scope of the Act. The Court emphasised that the Act's framework and language pointed towards a legislative intention to regulate long service leave for civilian employees, and that there was no indication that defence service was meant to be included. The appeals by the Commonwealth were therefore allowed.
