Town and Country Planning (Scotland) Act 1954

6 Where—

(a) the compensation includes an amount paid in respect of an interest in any land other than the relevant land ; or

(b) on such a sale as is mentioned in paragraph (b) of subsection (1) of section thirty-eight of this Act, the price paid included an amount in respect of damage sustained by an interest in land other than, but held with, the land in which the interest sold subsisted, being damage sustained by reason of the severance of the land or by reason that the interest in that other land was injuriously affected,

and the said amount exceeds what was, or in the appropriate circumstances (as defined in the said section thirty-eight) would have been, the loss of immediate value of that interest, then, for the purpose of determining whether that other land or any part thereof has an unexpended balance of established development value at any subsequent time, there shall be deducted from the original unexpended balance of established development value of that other land an amount equal to the excess, or so much thereof as was, or in the appropriate circumstances (defined as aforesaid) would have been, calculated by reference to that balance, and the original balance of that land or that part thereof shall be treated as having been reduced or extinguished accordingly immediately before that subsequent time.
