(1)Subject to the provisions of this section, the foregoing provisions of this Part of this Act (in this and the next following section referred to as " the survey provisions ") shall not apply to the administrative county of London.
(2)The London County Council or the council of a county borough may by resolution adopt the survey provisions as respects any part of the said county or of the county borough, as the case may be, specified in the resolution, and those provisions shall thereupon apply accordingly.
(3)If it appears to the Minister, as respects any part of the administrative county of London or of a county borough, that it is expedient that the survey provisions should apply thereto, and the London County Council or the council of the county borough, as the case may be, have not passed a resolution adopting those provisions as respects that part, the Minister may, after consultation with the council in question, make an order directing that those provisions shall apply to that part of the said county or county borough, as the case may be.
(4)The council of a county, other than the administrative county of London, may by resolution exclude from the operation of the survey provisions any part of the county which appears to the council to be so fully developed that it is inexpedient that those provisions should apply thereto:
Provided that a resolution under this subsection shall not have effect unless approved by the Minister.
(5)Where by virtue of a resolution under subsection (2) of this section, or of an order under subsection (3) thereof, the survey provisions apply to any part of the administrative county of London or of a county borough, those provisions shall have effect in relation thereto—
(a)in the case of a part of the administrative county of London, as if that part were a separate county and the London County Council were the council thereof, and as if, for references in those provisions to a county district, there were substituted references to a metropolitan borough;
(b)in the case of a part of a county borough, as if that part were a county and the county borough council were the council thereof;
(c)in either case, as if, for references in section twenty seven of this Act to the date of the commencement of this Act, there were substituted references to the date on which the resolution or order in question comes into operation;
(d)in either case, subject to the modification that subsection (5) of section thirty-three of this Act shall not apply as respects part only of the area to which the order or resolution relates.
(6)The making or revocation of a resolution or order under this-section, or the happening of any other event whereby land becomes or ceases to be comprised in an area to which the survey provisions apply, shall not, as respects any map or statement prepared before the event happened, affect the application in relation to the map or statement of subsection (4) of section thirty-two of this Act or that subsection as applied by subsection (1) of the last foregoing section.
