Although, at the time of the acquisition of the subject land, there had been no formal change in its zoning and it was still subject to interim development control, the council and the planning authority had approved the plan no. T. P. 172 which showed land in the situation of the subject land as a school site. For some time prior to the resumption of the land for the purposes of a school, the Education Department had conducted investigations and decided that it required the land as a school site. These facts could be ascertained by interested persons and would no doubt affect the price which the respondent might get for the land from a prospective purchaser. But in so far as any such alteration in value arose from the proposed establishment of the school on the land, it had, in accordance with s. 124 of the Public Works Act, 1912 N S W, to be disregarded. What that section required here was the assessment of the compensation to be paid for the taking of the land without regard to any alteration in its value because it was already known that the land was the site for a school. In so far as the designation of the school site on the plans of the respondent or in the provisions of the deed dated 29th March 1965, or in the draft planning scheme merely had the effect of spreading the knowledge that the land was to be a school site, s. 124 requires that any increase in value due to these matters should be disregarded. Furthermore, a reference in such plans, deed or planning scheme to the land as a school site, did not require that the land should be used for school purposes. Whether the land should be the site for a school depended upon the Education Department, regardless of what was shown in these plans and documents. Moreover, before us the appellant abandoned the contention that the provisions of the deed obliged the respondent to transfer the subject land free of cost to the appropriate person or authority for use as a school site. The affirmative answers of the Court of Appeal to question (2) were intended to mean (1) that the deed did not contain a promise by the respondent to make a school site available free of charge; (2) that the compensation must be assessed without reference to any public foreknowledge of the proposal to establish a primary school, even if the foreknowledge came from a draft planning scheme; and (3) that the fact that the respondent had suggested the proposal did not mean that it should be regarded. We consider that the answers of the Court of Appeal, understood in this way, were correct.
