Excise exemption and limitation rules: prior demand was time-barred, proof of actual payment was not mandatory, and classification required remand.

Limitation under the Central Excise Rules barred recovery for removals made before 8 June 1970, because the one-year period under Rule 10 read with Rule 173J had expired when notice was served on 8 June 1971. In construing excise exemption notifications, the phrase "has been paid" was held not to require proof of actual payment by the supplier; it was enough that the duty was payable on the raw material. The authorities also had to first determine whether the material was Item 26AA goods or scrap, because that factual classification governed the applicable exemption notification. The barred demand was quashed and the remaining issues were remitted for fresh consideration.

Issues: (i) whether the demand for the period prior to 8 June 1970 was barred by limitation under the Central Excise Rules; (ii) whether the expression "has been paid" in the exemption notifications required proof of actual payment of duty on the raw material; and (iii) whether the authorities had to determine the precise nature of the raw material before deciding which exemption notification applied.

Issue (i): whether the demand for the period prior to 8 June 1970 was barred by limitation under the Central Excise Rules.

Analysis: Rule 10 read with Rule 173J prescribed a one-year period for recovery of short-levied duty from the date of payment or adjustment. Since the notice was served on 8 June 1971, the demand relating to removals made from 1 June 1968 to 8 June 1970 fell outside the permissible period, though the later portion of that demand remained within time.

Conclusion: The demand for the period from 1 June 1968 to 8 June 1970 was barred by limitation and could not be sustained.

Issue (ii): whether the expression "has been paid" in the exemption notifications required proof of actual payment of duty on the raw material.

Analysis: The exemption provisions were construed in the light of the scheme of excise duty, under which the burden of payment on raw materials rested on the manufacturer of those materials. The Court held that a purchaser could not be denied exemption merely because proof of actual payment by the supplier was unavailable, and that the words "has been paid" meant that duty ought to have been paid, not necessarily that actual proof of payment had to be produced.

Conclusion: The authorities were wrong in insisting upon proof of actual payment of duty for claiming exemption.

Issue (iii): whether the authorities had to determine the precise nature of the raw material before deciding which exemption notification applied.

Analysis: The impugned orders did not clearly ascertain whether the raw materials used were articles falling under Item 26AA of the First Schedule or scrap covered by the alternative notification. That factual determination was necessary to decide the proper exemption regime, and the matter required reconsideration on that basis.

Conclusion: The matter had to be remanded for fresh decision on the nature of the raw material and the applicable exemption notification.

Final Conclusion: The petitions succeeded in part, the barred demand was quashed, and the remaining matters were sent back for fresh adjudication after determining the correct exemption position.

Ratio Decidendi: In construing exemption notifications under excise law, the phrase "has been paid" does not necessarily require proof of actual payment by the immediate purchaser and may mean that the duty was exigible and ought to have been paid; where the factual basis for the applicable exemption is unresolved, the assessment must be remitted for reconsideration.
