Power to acquire subsoil or airspace only
18.—(1) The Council may acquire compulsorily so much of, or such rights in, the subsoil of or the airspace over the land referred to in article 14(1) (power to acquire land) 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 Council acquires any part of, or rights in, the subsoil of or the airspace over land under paragraph (1), the Council is not required to acquire an interest in any other part of the land.
