Where—
(a)the holder of a conservation burden is a conservation body or, as the case may be, two or more such bodies; and
(b)that body ceases to be such a body, or those bodies cease to be such bodies (whether because an order under section 38(7) of this Act so provides or because the body in question has ceased to exist),
the conservation burden shall, on the body or bodies so ceasing, forthwith be extinguished.
