Strachan v Commonwealth

In *Strachan v Commonwealth*, the High Court of Australia considered the legal status of Papua, a territory that had been placed under the administrative control of the Governor-General of the Commonwealth in 1906. The dispute concerned the extent of the Commonwealth's legislative power over this territory following its acceptance.

The central legal issue before the Court was whether the Commonwealth had acquired sovereignty over Papua by virtue of its acceptance of the territory, and consequently, whether it possessed plenary legislative power in relation to Papua under the Australian Constitution. This involved an examination of the nature of the Crown's prerogative powers and how they were transferred to the Commonwealth upon federation and the subsequent acceptance of Papua.

The High Court reasoned that the acceptance of Papua by the Commonwealth, pursuant to the *Papua Act 1905* (Cth), did not operate to transfer to the Commonwealth the full sovereignty that the Crown had exercised over the territory. Instead, the Commonwealth acquired administrative control and the power to legislate for the peace, order, and good government of Papua, as provided by the Constitution. The Court held that the Commonwealth's legislative power was not plenary in the same way as the power of the United Kingdom Parliament, but was confined by the terms of the Constitution and the specific legislation under which the territory was accepted. The Court distinguished between the acquisition of administrative control and the acquisition of full sovereignty, concluding that the latter had not occurred.
