To turn now to the question of the enhancement of the value of the Company's remaining land to the west of Union Street resulting from the prospect of a new street frontage, it is clear that it is only by virtue of a special provision that the betterment of land from which land taken is severed can be taken into account for determining the compensation to be paid for the land taken or for the injurious affection of other land. Such special provisions have from time to time been made and sometimes they merely allow the betterment of retained land to be set off against any injurious affection of that land. In Harding v. Board of Land and Works [1] a provision in a Victorian Act that was susceptible of more general application was so confined. Section 12, however, makes it clear that in determining the compensation payable an allowance is to be made for enhancement of value of land adjoining the land taken which arises from the execution of the works for which the land is taken, whether or not the remaining land of the person entitled to compensation is injuriously affected, and we agree with Ross J. that there is no ground upon which to imply here any limitation of the sort adopted in Harding's Case [1] . There is, however, still a difficulty in applying r. (8) because, as was the case here, the works proposed may not have been carried out when compensation is to be assessed and it is therefore difficult to apply the words of r. (8) literally. As we read the sub-section, however, the allowance to be made in such a case as this is the judge's estimate of the enchancement, as at the time of the hearing, of retained adjoining land resulting from the prospect of the making of the street. This is how Ross J. understood and applied the provision and we think he was right in making an allowance for any enhancement in value of the Company's adjoining land by reason of the prospect of the new street frontage. It is true that in a case such as the present this construction of r. (8) does require an allowance estimated at a later date (i.e. May 1960) to be deducted from a value ascertained as at an earlier date (i.e. April 1949), and this may be thought to permit an injustice, but here, if there be an injustice, it is not more than the unanticipated result of the unusual circumstance that compensation was assessed ten years after the notice to treat had been given. As has already been said, we regard r. (9) as forbidding the calculation of enhancement as at the same date as at which the value of the land taken has to be assessed. Ross J. therefore correctly appreciated the law to be applied in relation to enhancement. The Company contended, however, that as the land retained is still being used as a market and this could continue indefinitely, no enhancement should be allowed on the basis that by reason of the new street frontage the land could be used in the future for other purposes. Under the Act, however, the judge is not concerned merely with the use to which the land retained is in fact put; that may, as here, be an uneconomic use. What in every case is of decisive importance is whether the prospect of the execution of works has, as at the date of the hearing, increased the value of the land retained and in this case his Honour has found with what seems to be every justification, that it did, that is, that a purchaser would pay more for the land in the new circumstances than he would have paid before. As his Honour points out, this is not a case where the land must always be used for a market; the Company and any purchaser from the Company could use it for other purposes and its value with the prospect of a frontage to a new street cannot be estimated as though it were nothing but a site for a market. The appellant's contention that no allowance should have been made under r. (8) therefore fails.
