PART 5 Powers of acquisition

Acquisition of subsoil only
21. (1) The undertaker may acquire compulsorily so much of, or such rights in, the subsoil of the land referred to in article 15(1) as may be required for any purpose for which that land may be acquired under that provision instead of acquiring the whole of the land.
(2) Where the undertaker acquires any part of, or rights in, the subsoil of land under paragraph (1), the undertaker is not required to acquire an interest in any other part of the land.
(3) Paragraph (2) does not prevent article 23 (acquisition of part of certain properties) from applying where the undertaker acquires a cellar, vault, arch or other construction forming part of a house, building or manufactory.
