The judgment against which this appeal is brought by special leave rejected a claim for rates by the City of Launceston against the Hydro-Electric Commission on the ground that the lands rated were exempt from rates by virtue of s. 115 of the Launceston Corporation Act 1941 Tas. which by sub-s. (1) provides as follows: - "Except as hereinafter provided, the council shall not levy or demand any rate whatever upon or in respect of - (I) Any land or building belonging to and occupied on behalf of Her Majesty." Two other provisions of the Act which are concerned with the rating of Crown land should be quoted. In s. 3, owner is defined to mean the person who is, or if it were let would be, entitled to receive the rent of the land and then follow these words: - " and, where used in relation to any land or building which is the property of - (I) Her Majesty, and is occupied by any person otherwise than on behalf of Her Majesty: or (II) - it includes the occupier of such property for the purposes only of the levying, payment, and recovery of rates." The other provision is s. 115, sub-s. (3), which is as follows: - "Where any land or building belonging to Her Majesty is occupied by any person for purposes other than those of Her Majesty the rates levied in respect of such land or building shall be payable by, and may be recovered from, such occupier and not otherwise." The significance of these provisions, and particularly the addition to the definition of owner, is that they indicate that the phrase "belonging to" in s. 115, sub-s. (1) (I) is synonymous with the phrase "is the property of", so that if land is to fall within the exemption provided thereby, it must be (1) the property of Her Majesty, and (2) occupied on behalf of Her Majesty.
