Excise duty recovery must follow the specific limitation rule, and exempt processed dyes could not be denied notification benefits.

Where excise duty was allegedly short levied at the stage of clearance from a licensed godown, recovery had to proceed under Rule 10 of the Central Excise Rules, 1944, and within its three-month limitation period; Rule 10A could not be used as a residuary route to bypass that specific time limit. On that footing, notices issued after the prescribed period were barred. The processed dyes were also treated as covered by the exemption notification dated 23 November 1961 because they were made from basic dyes on which duty had already been paid, so the demand and the administrative order sustaining it were illegal and were set aside.

Issues: (i) Whether the excise duty demands could be sustained under Rule 10A of the Central Excise Rules, 1944, or were recoverable only under Rule 10 within the prescribed limitation period; (ii) whether the processed dyes were covered by the exemption notification dated 23 November 1961 and the impugned demands and order were therefore illegal.

Issue (i): Whether the excise duty demands could be sustained under Rule 10A of the Central Excise Rules, 1944, or were recoverable only under Rule 10 within the prescribed limitation period.

Analysis: The governing scheme required assessment and collection of duty at the stage of clearance from the licensed godown. Rule 10 specifically dealt with recovery of duties short levied and imposed a written-demand requirement within three months from the date of payment or adjustment. Rule 10A was only a residuary provision and could operate only where the Rules made no specific provision. The demand in question related to duty allegedly short levied at clearance, and therefore fell within Rule 10 rather than Rule 10A. Since the notices were issued long after the three-month period, they were barred by limitation.

Conclusion: The demand notices were not sustainable under Rule 10A and were time-barred under Rule 10.

Issue (ii): Whether the processed dyes were covered by the exemption notification dated 23 November 1961 and the impugned demands and order were therefore illegal.

Analysis: The processed dyes were manufactured from basic dyes on which excise duty had already been paid, bringing them within the exemption granted by the notification. The department's attempt to proceed on the footing that no duty had been levied at all was inconsistent with the actual position and with the prior judicial construction of Rules 10 and 10A. The administrative order upholding the demands could not stand in the face of that legal position.

Conclusion: The processed dyes were covered by the exemption notification, and the impugned demands and order were illegal.

Final Conclusion: The impugned notices of demand and the order upholding them were set aside, with costs.

Ratio Decidendi: Where the Rules make a specific provision for recovery of excise duty short levied at clearance, the department must proceed under that provision and within the prescribed limitation period; the residuary recovery provision cannot be invoked to bypass that limit.
