As I understand it, "places" here means fixed localities. Whether or not a "place" must be part of the earth's surface together with any structures thereon, is an unnecessary question for the decision of the present case. If I had to answer it, I would be inclined to think that an upper storey of a building held by a strata title could be a place acquired for public purposes. But I doubt the proposition that obtaining a leasehold interest or a temporary licence to occupy a place would amount to acquisition in the relevant sense. Certainly I would not agree that the hiring of a hall for use as a polling booth on election day - as was mentioned in argument - or the use of a city park for an afternoon's military ceremonial would amount to an acquisition of a place by the Commonwealth for the purposes of s. 52. In short, as I understand s. 52, "places acquired by the Commonwealth" means places which upon acquisition the Commonwealth holds by virtue of a proprietary right.
Since in my opinion the doubt expressed by Windeyer J. was well founded, and the Commonwealth does not acquire a place simply by taking a lease of it, I do not need to express any opinion on the further question whether a portion of a building, to which a separate title can be obained, is a place within s. 52(i.). When the Commonwealth takes a lease of a place it does not "acquire" the place; what it acquires is a leasehold interest. A place will be acquired by the Commonwealth within s. 52(i.) only if the Commonwealth has, in one way or another, acquired the place itself, that is, has acquired full property in respect of the place. The words of s. 52(i.) stand in marked contrast to those of s. 51 (xxxi.). The latter provision refers to the acquisition of "property", a comprehensive term which of course includes leasehold interests. Section 52(i.) refers to "places" which have been "acquired". A constitutional provision whose effect, as has been held, is that when a place is acquired by the Commonwealth for public purposes the State in which the place is situated is deprived of the power to make a law with respect to that place and the operation of State laws formerly applicable within the place is terminated, is not likely to have been intended to apply whenever the Commonwealth obtains a right, however temporary, to occupy a place for public purposes - if the provision had such an application it would tend to throw the administration of the law into great confusion. But apart from that consideration the words "places acquired" do not, in their ordinary and natural sense, have the same meaning as "places in respect of which an interest is acquired".
