The second contention, on the other hand, found favour with the learned judge. With great respect we think it should not be sustained. If it were correct the Board could never give an approval of a subdivision conditionally upon the applicant's giving up land for any purpose, for roads, for public recreational areas, for foreshore reservation purposes, or for anything else, however relevant the condition might be to the observance of proper standards in local development. Given the necessary relevance of the conditions to the particular step which the Board is asked to approve, there is no foothold for any argument based on the general principle against construing statutes as enabling private property to be expropriated without compensation. The Act at its commencement took away the proprietary right to subdivide without approval, and it gave no compensation for the loss. But it enabled landowners to obtain approval by complying with any conditions which might be imposed, that is to say which might be imposed bona fide within limits which, though not specified in the Act, were indicated by the nature of the purposes for which the Board was entrusted with the relevant discretion: see Swan Hill Corporation v. Bradbury [1] ; Water Conservation and Irrigation Commission (N.S.W.) v. Browning [2] . If approval is obtained for the subdivision of one area of land by complying with a condition which requires the giving up of another area of land for purposes relevant to the subdivision of the first, it is a misuse of terms to say that there has been a confiscation of the second. For the giving up of the second a quid pro quo is received, namely the restored right to subdivide the first. It may be that the quid pro quo is inadequate, and that the landowner, though under no legal compulsion to give up the second area of land if he chooses to forego the idea of subdividing the first, is nevertheless under some real compulsion, in a practical sense, to submit to the loss of it because of the importance to him of obtaining the approval. But there is no room for reading the Act down in some fashion by appealing to a principle of construction that has to do with confiscation. If the Board has performed its statutory duty by giving approval to the subdivision subject only to conditions imposed in good faith and not with a view of achieving ends or objects extraneous to the purposes for which the discretion exists, the inescapable effect of the Act is that the landowner must decide for himself whether the right to subdivide will be bought too dearly at the price of complying with the conditions. The question in the case seemed to Virtue J. to be "whether the Board can expropriate for the benefit of the Crown and without any right to compensation substantial portions of the plaintiffs' land as a condition of their being able to use the balance remaining". With respect, this is not an accurate way of stating the question. There is here no expropriation for the benefit of the Crown in any real sense of the expression. True it is that if the land required for open space reserves is transferred to the Crown for park and recreation purposes as the conditions require, the beneficial title to it will pass to or be vested in the Crown without legal fetter. There will be a moral obligation on the Government to keep it reserved for the purposes mentioned, but no legally enforceable obligation. The ultimate sanction must be political only. But the fact remains that the Board has stipulated for the transfer solely in order to serve purposes which it is justified in serving by an exercise of its power to impose conditions, and has done so because a reliance upon the continuing good faith of the Administration provides the only available means by which the fulfilment of those purposes may be practically secured.
