“(2A)Subject to subsection (2B) below, where—
(a)a person entitled to do so has at any time made a claim for an allowance under any of the preceding Parts of this Act, other than Part II, and
(b)that claim is for an allowance in respect of capital expenditure relating, in whole or in part, to the construction, acquisition or provision of an asset,
no capital expenditure (whenever incurred) relating to the provision of that asset shall, by virtue of Chapter VI of Part II, be brought into account at any time after that time by any person at all.
(2B)Subsection (2A) above shall not prevent capital expenditure from being brought into account by virtue of Chapter VI of Part II where—
(a)the only claim made under a provision of this Act not contained in Part II is a claim under Part I or Part VII; and
(b)section 56C or 56D would apply by reference to that claim in relation to any claim for that expenditure to be so brought into account.
(2C)Where capital expenditure relating to the provision of any asset has at any time been brought into account by virtue of Chapter VI of Part II by any person entitled to do so, no capital expenditure (whenever incurred) relating to the construction, acquisition or provision of that asset shall, at any time after that time, be the subject of a claim made, by any person at all, for an allowance under any of the preceding Parts of this Act other than Part II.
(2D)For the purposes of subsections (2A) to (2C) above a person shall be taken to bring an amount of capital expenditure into account by virtue of Chapter VI of Part II if—
(a)he makes a claim for an allowance in respect of that expenditure, as expenditure on the provision of a fixture within the meaning of that Chapter,
(b)he makes a return in which that expenditure is taken into account, as expenditure on the provision of such a fixture, in determining his qualifying expenditure for the purpose of an allowance or charge under section 24, or
(c)he gives notice of any such amendment of a return as provides for that expenditure to be taken into account as mentioned in paragraph (b) above.”
(2)In subsection (3) of that section after the definition of “capital expenditure” there shall be inserted “and
