CAS-4 valuation of captive consumption and suppression-based extended limitation applied where cost certificates omitted material expenses.

Captively consumed diesel engines must be valued on the basis of cost of production under CAS-4 where no market price is available, and incomplete cost certificates that omit material overheads do not satisfy the prescribed valuation standard; the assessable value must therefore be reworked accordingly. Where the declaration is based on such an incomplete certificate and the omitted cost elements are not disclosed, extended limitation may be invoked on the ground of suppression or misdeclaration. A penalty under Rule 209A cannot be sustained unless the necessary ingredients are specifically found on the record.

Issues: (i) whether the assessable value of captively consumed diesel engines was required to be reworked on the basis of cost of production under CAS-4 and the Board's circular; (ii) whether invocation of the extended period was justified on the facts; (iii) whether the penalty imposed under Rule 209A could be sustained.

Issue (i): Whether the assessable value of captively consumed diesel engines was required to be reworked on the basis of cost of production under CAS-4 and the Board's circular.

Analysis: The goods were not sold and comparable market value was unavailable, so valuation had to proceed on cost structure. The certificate relied upon by the assessee did not include certain overheads and related costs, while the later joint certificate and the Board's clarification directed that captive consumption cost should be determined in accordance with CAS-4. The proper basis for valuation therefore had to be the cost of production computed under the prescribed standards.

Conclusion: The assessable value required re-determination in accordance with CAS-4, and the matter was remanded for fresh adjudication.

Issue (ii): Whether invocation of the extended period was justified on the facts.

Analysis: The valuation declaration was based on an incomplete certificate, and the omitted cost elements were not disclosed to the department. The incorrect adoption of value came to light only after search and scrutiny of records. Approval of the price list on the basis of an inaccurate certificate did not protect the assessee from a charge of suppression or misdeclaration.

Conclusion: Invocation of the extended period was upheld.

Issue (iii): Whether the penalty imposed under Rule 209A could be sustained.

Analysis: No finding had been recorded that the ingredients of Rule 209A were satisfied in respect of the penalised employee. In the absence of such a finding, the penalty could not stand.

Conclusion: The penalty under Rule 209A was set aside.

Final Conclusion: The assessee succeeded to the extent of remand for fresh valuation and deletion of the employee penalty, but the finding on limitation and suppression was adverse.

Ratio Decidendi: Where captive consumption valuation is based on an incomplete cost certificate that omits material cost components, the department may invoke the extended period on the ground of suppression or misdeclaration, and valuation must be reworked on the prescribed cost-of-production basis.
