Rescission of notification under Central Excise Act withdraws prior notification's effect, subject to pre-existing actions preserved. The Central Government, invoking its authority under the Central Excise Act, rescinded Notification No. 9/2012-Central Excise (N.T.), dated 17 March 2012, withdrawing that notification in the public interest while preserving a savings provision that leaves intact things done or omitted before the rescission.
