Appeals to Commissioner of Central Excise (Appeals): limitation periods shortened with discretionary condonation retained. Any person aggrieved by a decision of an adjudicating authority subordinate to the Principal Commissioner or Commissioner of Central Excise may appeal to the Commissioner of Central Excise (Appeals). Appeals must be in the prescribed form and verified. Time limits: pre-2012 decisions-appeal within three months with discretionary three-month extension for sufficient cause; post-2012 decisions-appeal within two months with discretionary one-month extension for sufficient cause.
