Power to make laws for the government of the Australian Capital Territory is derived from s. 122 of the Constitution. Section 61 in relation to the Territory in my opinion includes traditional executive power broadly embraced in the description of "the prerogative" exercisable in the Territory. Just as the legislative power for the Territory derived from s. 122 is non-federal in the sense I used that description in Spratt v. Hermes [1] , so it seems to me that the executive power in relation to the Territory is not federally restrained. Consequently, whatever the position in other parts of Australia, the executive, unless its power is relevantly reduced by statute, may in my opinion do in the Territory upon or with respect to land in the Territory anything which remains within the prerogative of the Crown. Here the land, namely, Black Mountain, is the property of the Commonwealth having been vested in the Commonwealth as part of the Australian Capital Territory by the Seat of Government Acceptance Act, 1909-1938. But what the executive does upon and in respect of such lands will be done by virtue of the prerogative and not by virtue of proprietorship. There can be no objection in my opinion to the Commonwealth, in the absence of any statutory provisions, establishing parks, gardens, sports grounds, tourist facilities and the like upon land it possesses in Canberra. But, of course, funds to be expended on any such activity must be the subject of due appropriation according to law (s. 83 of the Constitution). Such a conclusion would cover the erection in the present circumstances of a restaurant and viewing facilities, assuming that there is no relevant statutory impairment of the prerogative.
