The appropriate supervisory body may, on the application of the council of any county county borough, metropolitan district or London borough, direct that the powers conferred by section 9 above on the appropriate supervisory body shall, as respects land in the area of the council, be exercisable by that council instead of by the appropriate supervisory body.
If the appropriate supervisory body refuses to comply with any application under subsection (1) above, the council by which the application was made may appeal against the refusal to the relevant Minister and he may, if he thinks fit, require the appropriate supervisory body to comply with the application.
Without prejudice to the power of the appropriate supervisory body to give a new direction, the appropriate supervisory body may—
revoke any direction given under subsection (1) above.
