“In assessing the compensation to be paid by the acquiring authority under this Act regard shall be had not only to the value of the land to be purchased by the acquiring authority, but also to the damage, if any, to be sustained by the owner of the land by reason of the severing of the land purchased from the other land of the owner, or otherwise injuriously affecting that other land by the exercise of the powers conferred by this or the special Act.”
“18. The assessment of this form of compensation is generally achieved by determining the value of the retained land before severance, i.e. on the valuation date but disregarding the effect of the acquiring authority’s scheme, and deducting from it the value of the retained land after severance, i.e. on the same date but taking into account the effect of the scheme and of the severance of the retained land from the land taken. The necessary assessment must be carried out as at the date of entry, in this case,10 November 2014 .”
“... As a general rule, without an express contractual or statutory instruction to do so (and there is none in section 7) it would always be wrong to value land as if with knowledge of matters which were not known, and could not have been known, at the valuation date…”
“The law expects those who claim compensation to behave reasonably. If a reasonable person in the position of the claimant would have taken steps to reduce the loss, and the claimant failed to do so, he cannot fairly expect to be compensated for the loss or the unreasonable part of it. Likewise if a reasonable person in the position of the claimant would not have incurred, or would not incur, the expenditure being claimed, fairness does not require that the authority should be responsible for such expenditure.”
