(1)Where, immediately after the time when the adjustment of claim holdings was completed, any land taken as a whole had an original unexpended balance of established development value, and at any time thereafter (whether before or after the commencement of this Act) an act or event occurs or has occurred in relation to part of that land such that, in accordance with any of the preceding provisions of this Part of this Act, an amount is required to be deducted from the original unexpended balance of that part of that land for the purpose of determining whether it has or had an unexpended balance of established development value at any subsequent time, then (without prejudice to the operation of any of the preceding provisions of this Part of this Act with respect to any part of the land taken separately) the land taken as a whole shall be treated as not having (or as not having had) any such balance at that subsequent time.
(2)Where in accordance with any of the preceding provisions of this Part of this Act an amount is required to be deducted from the original unexpended balance of established development value of any land, there shall be attributed to the various parts of that land so much of that amount as might reasonably be expected to have been attributed thereto if the authority determining the amount had been required to apportion it between those parts in accordance with the same principles as applied to its determination.
(3)Where two or more acts or events occur or have occurred in relation to the same land (whether before or after the commencement of this Act) such that, in accordance with any of the preceding provisions of this Part of this Act, an amount is required to be deducted from the original unexpended balance of established development value of that land or any part thereof, those provisions shall apply cumulatively, and the requisite deduction from the original unexpended balance of established development value of that land shall be made by reference to each of those acts or events.
