Strict construction of exemption notifications bars retrospective use of a later formula amendment for cotton fabric valuation.

Exemption notifications must be construed strictly, so a later amendment introducing a new formula for determining the average count of cotton fabrics cannot be treated as a retrospective clarification unless the instrument itself so provides. On that reasoning, the benefit of Notification No. 226/77 could not be extended to earlier clearances on the basis of Notification No. 7/78. The note also records that limitation under Rule 10 read with Rule 173J of the Central Excise Rules, 1944, would bar demands beyond the admitted outer limit, requiring recalculation of duty within the permissible period.

Issues: (i) whether Notification No. 7/78 dated 17th Jan, 1978, amending the formula for determining the average count of cotton fabrics, could be treated as a clarification and applied retrospectively to earlier clearances; (ii) whether the demand was barred by limitation under Rule 10 read with Rule 173J of the Central Excise Rules, 1944.

Issue (i): whether Notification No. 7/78 dated 17th Jan, 1978, amending the formula for determining the average count of cotton fabrics, could be treated as a clarification and applied retrospectively to earlier clearances.

Analysis: The exemption under Notification No. 226/77 depended on the prescribed formula for determining average count. The difficulty in working out average count under the unamended formula did not justify going outside the notification or treating the later amendment as a mere explanation. Exemption notifications are to be construed strictly, and relief can be granted only within their terms. The later notification introduced a new method to overcome the practical difficulty and could not be read as an automatic retrospective clarification.

Conclusion: The benefit of Notification No. 226/77 could not be extended retrospectively on the basis of Notification No. 7/78, and the exemption relief was denied.

Issue (ii): whether the demand was barred by limitation under Rule 10 read with Rule 173J of the Central Excise Rules, 1944.

Analysis: The order accepted that some demands were within time and that demand beyond the admitted outer limit of limitation could not survive. The limitation objection was therefore upheld to the extent recognised by the department and the lower authorities were required to revise the demand accordingly.

Conclusion: The demand was time barred beyond the permissible period, and the limitation finding was upheld.

Final Conclusion: The appeal succeeded on the exemption issue and failed on the limitation issue, resulting in a partial allowance with consequential recalculation of duty.

Ratio Decidendi: An exemption notification must be construed strictly, and a later amendment introducing a new method for computation cannot be treated as a retrospective clarification unless the instrument itself so provides.
