Where the order giving rise to a demand of amount for which a certificate for recovery has been issued has been modified in appeal or other proceedings under this Act, and, as a consequence thereof, the demand is reduced but the order is the subject-matter of a further proceeding under this Act, the authorised officer shall stay the recovery of such part of the amount of the certificate as pertains to the said reduction for the period for which the appeal or other proceeding remains pending.
