90(1)Where permission for any development of land was granted, at any time after 21st July 1943 and before the appointed day, on an application in that behalf made under an interim development order, then, if and so far as that development was not carried out before the appointed day and the permission was in force immediately before that day, planning permission shall be deemed to have been granted in respect thereof subject to the like conditions (if any) as were imposed by the permission under the interim development order as it had effect immediately before the appointed day;
Provided that this sub-paragraph shall not apply in relation to any development for which permission was required before the appointed day under the [1935 c. 47.] Restriction of Ribbon Development Act 1935 unless that permission was also granted.
(2)The provisions of section 45 of this Act shall apply in relation to planning permission which is deemed to have been granted by virtue of this paragraph as if it had been granted on an application under Part III of this Act; and, in relation to any order made under that section for the revocation or modification of any such permission, any reference in section 164(3) of this Act to the grant of permission shall be construed as a reference to the grant of the permission under the interim development order.
(3)Where permission for any development of land was granted as mentioned in sub-paragraph (1) of this paragraph, and permission for that development was also granted under the [1935 c. 47.] Restriction of Ribbon Development Act 1935 then, if the permission so granted under the said Act of 1935 was granted subject to conditions, those conditions shall be treated for the purposes of this paragraph as conditions imposed by the permission granted under the interim development order.
