The Rules prescribe forms, signature and copy requirements, filing modalities and accompanying documents for appeals and applications under the Central Excise Act, regulate admissibility of additional evidence before the Commissioner (Appeals) with required written reasons and opportunity for the adjudicating authority, set qualifications for authorised representatives, and identify procedural offices and deemed filing rules.
