Modvat credit on export-related inputs and limitation were linked to final non-adjustability, not automatic lapse under the rules.

Modvat credit linked to exported goods was treated as carrying an independent refund entitlement where adjustment was not possible, and limitation under Section 11B was held to run only from the point when non-adjustability became finally clear, not from the introduction of the lapsing rule. Disallowance of credit for inputs contained in work in progress and in shop-made forgings and springs was rejected because the quantification lacked adequate factual basis. The disallowance relating to inputs in stock was not finally decided and was remitted for fresh arithmetical verification and limited reconsideration on computation.

Issues: (i) Whether Modvat credit attributable to exported goods could be denied on the ground of lapse under Rule 57F(4A) and whether refund was barred by limitation; (ii) whether the disallowance of credit relatable to inputs contained in work in progress and in shop-made forgings and springs was sustainable; (iii) whether the disallowance relating to inputs lying in stock required fresh arithmetical verification.

Issue (i): Whether Modvat credit attributable to exported goods could be denied on the ground of lapse under Rule 57F(4A) and whether refund was barred by limitation.

Analysis: Rule 57F(4A) was construed as overriding only such parts of Rule 57F(4) as were inconsistent with the lapsing provision. The credit attributable to exported goods was treated as carrying an alternative entitlement to refund where adjustment was not possible. The relevant date for limitation under Section 11B was held to arise only when it became finally clear that the credit could not be adjusted, and not merely on the introduction of the lapsing provision. The alternative refund claim was therefore not rejected on limitation and the statutory bar was not treated as defeating the export-related credit entitlement.

Conclusion: The assessee was held entitled to claim refund of the credit attributable to exported goods, and limitation did not defeat that entitlement.

Issue (ii): Whether the disallowance of credit relatable to inputs contained in work in progress and in shop-made forgings and springs was sustainable.

Analysis: The quantification adopted for work in progress was found to rest on a theoretical method without adequate basis for rejecting the assessee's data, and the percentage applied by the cost auditor was not accepted. As to forgings and springs, the record showed that the items were manufactured and moved for use in the factory and were not properly brought within the disallowance exercise. The earlier remand order had also indicated that denial of credit on this count was not correct.

Conclusion: The disallowance of credit for work in progress and for shop-made forgings and springs was set aside, and the credit was allowed to the assessee.

Issue (iii): Whether the disallowance relating to inputs lying in stock required fresh arithmetical verification.

Analysis: The figures placed before the Tribunal showed a possible arithmetical mismatch in the amount disallowed under this head. The Tribunal held that the correctness of the computation needed to be verified by the Commissioner, and if necessary a fresh adjudication could follow on that limited question only.

Conclusion: The issue was remitted for arithmetical verification and limited reconsideration.

Final Conclusion: The assessee succeeded substantially on the disputed Modvat credit claims, with one head allowed outright and another sent back only for verification of the computation; the case was not finally concluded in full because limited further adjudication remained on one item.

Ratio Decidendi: Where a lapsing provision does not clearly extinguish an independent refund entitlement, the credit attributable to exports cannot be denied merely because it is not immediately adjustable, and limitation runs only from the point when non-adjustability becomes finally ascertainable.
