Refund limitation and exemption conditions under excise law turn on duty payment date, express notification terms, and captive consumption rules.

Section 11B limitation for refund claims runs from the date duty is paid, not from the end of the financial year, so the later refund claim was partly time-barred. An exemption notification cannot be burdened with an implied declaration requirement unless the condition is expressly stated, so exemption could not be refused on that ground. Captively consumed inputs did not qualify for the exemption where the finished goods were wholly exempt, although such captive clearances were excluded from the aggregate value of clearances under the notification. Relief was confined to the finished product for the later period only.

Issues: (i) whether the refund claim was barred by limitation under Section 11B of the Central Excises and Salt Act, 1944; (ii) whether a declaration was a mandatory condition for availing exemption under Notification No. 80/80; and (iii) whether duty on captively consumed inputs was refundable and whether such inputs were to be included in the aggregate value of clearances for the purpose of the exemption.

Issue (i): whether the refund claim was barred by limitation under Section 11B of the Central Excises and Salt Act, 1944.

Analysis: The limitation prescribed by Section 11B runs from the date of payment of duty and not from the end of the financial year, even where the exemption notification is linked to annual turnover. The view that limitation would commence from the last date of the financial year was rejected as unsustainable.

Conclusion: The claim dated 27-4-1982 was correctly rejected as time-barred, and the claim dated 5-4-1982 was time-barred for the earlier period but not for the period on and from 4-10-1981.

Issue (ii): whether a declaration was a mandatory condition for availing exemption under Notification No. 80/80.

Analysis: A condition cannot be read into an exemption notification unless it is expressly provided. The notification, as applied to the appellants, did not incorporate the declaration requirement relied upon by the lower appellate authority, and the amendment referred to did not govern the factual situation in issue.

Conclusion: The finding that exemption was unavailable for want of declaration was rejected.

Issue (iii): whether duty on captively consumed inputs was refundable and whether such inputs were to be included in the aggregate value of clearances for the purpose of the exemption.

Analysis: Under the Central Excise Rules, captive removal without duty is permissible only where the finished goods are not wholly exempt or chargeable to nil rate of duty. Since the finished product itself was claimed to be fully exempt under Notification No. 80/80, the captively consumed input could not be treated as eligible for exemption. However, the value of such captive clearances was not to be included in computing the aggregate value of clearances under the notification, as the notification itself excluded them on its terms.

Conclusion: Refund was allowable only for the finished product for the period on and from 4-10-1981, and not for the captively consumed input; the exclusion of captive clearances from aggregate turnover was upheld.

Final Conclusion: The appeal succeeded only in part. The Tribunal upheld limitation against the older refund period and refused exemption for captively consumed inputs, while granting the appellants relief for the later refund period in respect of the finished product alone.

Ratio Decidendi: Limitation under Section 11B begins on the date of payment of duty, and an exemption notification cannot be expanded by implication to create an unexpressed condition; captive inputs cannot share the benefit of an exemption where the finished goods are wholly exempt.
