by the bankrupt, or
where the bankrupt has not made an application within the prescribed period, by the official receiver.
An application under subsection (2) may not be made—
during the period specified in section 262(3)(a) during which the creditors' decision can be challenged by application under section 262,
while an application under that section is pending, or
