45 Once the Board of Valuers has made the required valuation of the unaffected value of the subject land it is required to communicate that valuation to the landowner and to the responsible authority (s 183(2)). Upon the responsible authority receiving that valuation it is to advise the landowner of the minimum price at which the land may be sold without affecting the amount of compensation, if any, payable to him or her (s 183(3)). Counsel for the applicant submitted, and I accept, that the reason for this requirement is to give assurance to the landowner that he or she may proceed to sell the subject land to some purchaser at or above the price so notified by the responsible authority, without being in jeopardy of being faced with an allegation, in the proceedings for the determination of the amount of compensation payable for injurious affection, that the land was not sold at a price less than its unaffected value as so determined (or that if it were such a sale would exclude or modify any right to compensation for injurious affection) or that the owner had not sold the land in good faith or had failed to take reasonable steps to obtain a fair and reasonable price - see s 177(a)(i) and (iii). Of course, such a notification by the responsible authority would not, and could not, determine what the affected value of the land at the date of sale actually was. The responsibility for that determination rests upon the arbitrator or any other person determining the claim for compensation for injurious affection, but the notification from the responsible authority of the minimum price at which it considered that the land might be sold without affecting the amount of compensation, if any, payable for injurious affection at least forewarns the landowner of the position adopted by the responsible authority and, accordingly, gives the landowner notice of potential consequences if the land were to be sold at less than the price notified by the authority.
