Where two or more payments are payable in respect of the same claim holding by virtue of the preceding provisions of this Part of this Act, other than the last preceding section, the authority determining the amount of any such payment shall apportion that amount between the different parts of the area of the claim holding in such manner as appears to that authority proper, and if the aggregate of the portions of the principal amounts of the respective payments so apportioned to any part of the area of the claim holding would, apart from the provisions of this subsection, exceed the fraction of the value of the claim holding attaching to that part of the area thereof, those portions shall be reduced rateably so that the aggregate of them is equal to the said fraction, and the said principal amounts shall be treated as reduced accordingly.

Where two or more payments are payable in respect of the same claim holding by virtue of the last preceding section, the aggregate of the principal amounts of those payments shall not exceed the value of the claim holding or, where that value is treated as reduced in accordance with subsection (6) of the last preceding section, that value as so reduced.
