Sir,
The case is having some confusion. It is not mentioned whether the case pertains to the State or the Central Authority. In the case of the Central Authority, there are monetary ceiling limits prescribed to proper officers. In such cases, lower ranking authority cannot pass an order beyond its limitations.
Under state administration, the Additional Commissioner is not the adjudicating authority. The Additional Commissioner on Enforcement can issue assignments for inspection to the officers under his control, designated as Deputy Commissioner, Assistant Commissioner and Commercial Tax Officer, without monetary ceiling limits. They are issuing DRC-1A and DRC-01 under the office of the Additional Commissioner and then forwarding for Adjudication to the Audit Officers of the Administrative wing, the Joint Commissioner, DGSTO of the respective jurisdiction, since the enforcement authorities are not empowered to pass the adjudication order. Auditing Authority, probably in your case, is an Assistant Commissioner who may be the authority for passing the order. In such a situation, you are answerable to the Assistant Commissioner and not to the Additional Commissioner. DRC-07 cannot be in the name of the Additional Commissioner. Something wrong has happened there. Before going to the appeal, you can apply for rectification. But it is stated that it was appealed before the FAA, but the result was not mentioned. If you find any mistakes in the Order in Original, you can appeal. Technical errors can be rectified u/s 161 if it is within the time limitation.
