This section applies where—
Subject to section 248, in a case where the whole of the consideration for the disposal was applied as mentioned in subsection (1)(c) above, the landowner, on making a claim as respects the consideration so applied, shall be treated for the purposes of this Act—
If part only of the consideration for the disposal of the old land was applied as mentioned in subsection (1)(c) above, then, subject to section 248, if the part of the consideration which was not so applied ("the unexpended consideration") is less than the amount of the gain (whether all chargeable gain or not) accruing on the disposal of the old land, the landowner, on making a claim as respects the consideration which was so applied, shall be treated for the purposes of this Act—
Nothing in subsection (2) or subsection (3) above affects the treatment for the purposes of this Act of the authority by whom the old land was acquired or of the other party to the transaction involving the acquisition of the new land.
For the purposes of this section—
Subsections (2A) and (2C) of section 175 shall apply in relation to this section as they apply in relation to section 152 (but as if the reference in subsection (2C) to the new assets were a reference to the new land).
Where this section applies, any such amount as is referred to in subsection (2) of section 245 shall be treated as forming part of the consideration for the disposal of the old land and, accordingly, so much of that subsection as provides for a deemed disposal of other land shall not apply.
The provisions of this Act fixing the amount of the consideration deemed to be given for the acquisition or disposal of assets shall be applied before this section is applied.
In this section—
"land" includes any interest in or right over land; and
"authority exercising or having compulsory powers" shall be construed in accordance with section 243(5).
