22. Suspension of right to postponement of liability to be called up for national service.-
(1) The Central Government may, if it is satisfied at any time that by reason of the gravity of the situation it is necessary so to do, by order-
(a) cancel, either generally or in relation to a specified class of qualified persons, all postponement certificates in force at the date of the order, and
(b) abrogate, either generally or in relation to a specified class of qualified persons, any right to apply for the grant of a postponement certificate and any right to appeal from the refusal to grant such a certificate, and may, by order, vary or revoke any order in force under this section, without prejudice however to the previous effect of that order.
(2) Where, on the day on which an order comes into force under this section abrogating any right to appeal from the refusal to grant a postponement certificate, an appeal preferred by a person to whom the order applies or the time for preferring such appeal by such person has not expired, the appeal shall be deemed to be dismissed or the time shall be deemed to expire on the expiry of that day.
