Subject to the provisions of this section, the Minister may approve any development plan submitted to him under the last preceding section, either without modification or subject to such modifications as he considers expedient.

The Minister shall not approve a development plan which designates any land as subject to compulsory acquisition if it appears to him that the acquisition is not likely to take place within ten years from the date on which the plan is approved.

The Minister shall not, except with the consent of all persons interested, approve a development plan subject to a modification designating as subject to compulsory acquisition any land not so designated in the plan as submitted to him.

Where a development plan as submitted to the Minister designates as subject to compulsory acquisition any such land as is mentioned in paragraph 9 of the First Schedule to the Acquisition of Land (Authorisation Procedure) Act, 1946 (which relates to land of local authorities and statutory undertakers and inalienable land of the National Trust), then, if objection to the proposed designation is duly made by the local authority or statutory undertakers or the National Trust, as the case may be, and is not withdrawn, the land shall not be so designated except in pursuance of an order made by the Minister, and any such order shall be subject to special parliamentary procedure.

In relation to agricultural land within the meaning of the Rating and Valuation (Apportionment) Act, 1928, subsection (2) of this section shall have effect as if for the words “ten years ” there were substituted the words “seven years ”.
