The effect of this section fell for consideration in In re Smith and Minister for Home and Territories [1] , a case in which the retained land had not depreciated but had been enhanced in value by reason of the acquisition. The Commonwealth had constructed a railway which passed through portion of the land included in the claimants' lease and had acquired by compulsory process for the purposes of the railway certain portions of the leased land. It seems that the land in question had been taken to provide water for the construction of the railway. One of the questions that fell to be decided by Powers J. was whether the enhancement referred to in s. 28 (1) (c) of the Lands Acquisition Act 1906 was the enhancement caused only by the acquisitions in question, or the enhancement caused by the construction and use of the railway, including the works carried out on the lands in question (2). From the judgment of Power J. it appears [2] that the lands on which the railway had been constructed had not yet been acquired and that the contention of the claimants was that the taking of the land for water for the railway construction could not in itself possibly enhance the value of the rest of the land. In reply to this contention it was said on behalf of the Minister, inter alia, that compensation was to be determined in accordance with the principles set forth in s. 28, and that under that section Powers J. in assessing compensation was required to set off the amount by which he found that the other land of the claimants adjoining the land taken was enhanced "by reason of the carrying out of the public purpose for which the acquired land was acquired"; not the enhancement caused only by acquiring any particular piece of land. Powers J. accepted the contention made on behalf of the Minister; he said [3] :
I hold that I am required to find to what extent the rest of the adjoining lands of the claimants is enhanced in value by reason of carrying out the public purpose for which the land in question was acquired, namely, for the construction and use of a railway from Port Augusta to Kalgoorlie.
It was pointed out in argument before us that the report does not make it clear how his Honour applied this decision to the facts of the case [1] . I have obtained a copy of the award made by Powers J. and it shows that, so far as is now material, he determined as follows:
I determine that the claimants are not entitled to any compensation in respect of the four portions of land acquired by the Commonwealth by compulsory process on the ground that the other lands of the claimants adjoining the lands acquired are enhanced in value by the carrying out of the public purpose - the railway from Port Augusta to Kalgoorlie - to the extent of £2,271.10.0 at least, and because I hold that the Commonwealth is entitled to set off that sum against the £2,271.10.0 I would have otherwise determined the claimants were entitled to as compensation in respect of the lands above-mentioned.
It seems quite clear that Powers J. held that under s. 28 (1) (c) he was bound to have regard to the enhancement of the land retained which resulted from the carrying out of the public purpose on land other than the acquired land in question. If the effect of s. 28 (1) (c) was that enhancement is to be found by considering the effect of carrying out the public purpose, even though it is not carried out on the land acquired, the same must be true of depreciation. The decision therefore gave a different effect to the section from that which the English cases have given to s. 63 of the Lands Clauses Consolidation Act, and is quite opposed to the contention of the Solicitor-General. Of course, being the decision of a single Justice, it does not bind us, but as it has stood unchallenged for over fifty years, it is of considerable persuasive authority. The Lands Acquisition Act 1906 was twice amended after this decision but no alteration was made to s. 28 and when that Act was repealed by the Lands Acquisition Act 1955 Cth, s. 23 (1) (c) was enacted in its present form. Perhaps it is unnecessary to go so far as to say that these circumstances call for the application of the principle discussed by Lord Macmillan in Barras v. Aberdeen Steam Trawling and Fishing Co. Ltd. [2] , that where the language of a statute has received judicial inter-pretation and Parliament again employs the same language in a subsequent statute dealing with the same subject matter there is a presumption that Parliament intended that the language so used by it in the subsequent statute should be given the meaning which meantime has been judicially attributed to it. However, the history of the legislation confirms me in the view that s. 23 (1) (c) should be construed according to its own terms and not upon the assumption that the Parliament intended to give its words the same effect as that which the authorities had held should be given to the different words of the English and the Canadian statutes.
