s 4
(1) An order as confirmed by the Minister under the last foregoing paragraph shall not authorise the local authority to purchase any land which the order would not have authorised them to purchase if it had been confirmed without modification. (2) An order under section forty-three of this Act shall not, as confirmed under the last foregoing paragraph,— (a) authorise the local authority to purchase as being land comprised in a clearance area any land shown in the order as submitted as being outside that area ; or (b) authorise the local authority to purchase compulsorily any building on less favourable terms with respect to compensation than the terms on which the order would have authorised them to purchase the building if the order had been confirmed without modification. (3) If the Minister is of opinion that any land included by the local authority in a clearance area should not have been so included, he shall in confirming an order made under section forty-three of this Act modify it so as to exclude that land for all purposes from the clearance area, but if in any such case he is of opinion that the land may properly be purchased by the authority under subsection (2) of that section, he shall further modify the order so as to authorise the local authority to purchase that land under that subsection and not as being land comprised in a clearance area. (4) The Minister may confirm an order made in connection with a clearance area notwithstanding that the effect of the modifications made by him in excluding any building from the clearance area is to sever that area into two or more separate and distinct areas, and in any such case the provisions of this Act relating to the effect of the order when confirmed and to the proceedings to be taken subsequent to the confirmation thereof shall apply as if those areas formed one clearance area.
