(1)In exercise of the powers of section 13 above the authorised undertaker may, as regards any land authorised to be acquired under that section, compulsorily acquire—
(a)so much of the subsoil of the land; or
(b)such servitudes or other rights over the land,
as may be required for any purpose for which that land may be acquired under that section.
(2)Rights acquired under subsection (1) above may be heritable or moveable, and may be created as new rights for the purpose of acquisition under this section.
(3)Where the authorised undertaker acquires subsoil or a right over land under subsection (1) above, the authorised undertaker shall not be required to acquire an interest in the land which is greater than that right.
(4)Accordingly section 90 of the 1845 Lands Act (which provides that the owner of a house, building or manufactory who is willing to sell the whole property cannot be required to sell only part) shall not apply to any compulsory acquisition under this section or under section 15 below.
(5)Subject to subsections (6) and (7) below, the Lands Clauses Acts, as applied by this Act, shall have effect with the modifications necessary to make them apply to the compulsory acquisition of new rights under this section or under section 15 below as they apply to the compulsory acquisition of land.
(6)As so having effect, references in those Acts to land shall be treated as, or as including, references to new rights or to the land over which new rights are to be exercisable.
(7)Section 61 of the 1845 Lands Act (estimation of purchase money and compensation) shall apply to the compulsory acquisition of such a right as if for the words from “value” to “undertaking” there were substituted the words “extent (if any) to which the value of the land in or over which the right is to be acquired is depreciated by the acquisition of the right”.
