Merseytravel may compulsorily acquire so much of the subsoil of the land within the permanent limits as may be required for any purpose for which that land may be acquired instead of acquiring the whole of the land.

Where Merseytravel acquires any part of the subsoil of land under paragraph (1) Merseytravel shall not be required to acquire an interest in any other part of the land.

Paragraph (2) shall not prevent article 39 from applying where Merseytravel acquires a cellar, vault, arch or other construction forming part of a house, building or factory.
