Excise duty set-off allows excess payment to be netted against short payment, and provisional assessment defeats limitation objections.

The excise adjustment scheme required the department to reconcile duty assessed with duty actually paid and to net off excess payment against short payment where both could arise in the same period. A separate refund claim was not necessary to defeat the adjustment mechanism, and the department had to examine the overall duty position rather than refuse set-off automatically. The limitation objection also failed because the relevant assessments were provisional, so the adjustment claim was not barred as a time-time refund claim. The resulting position was that excess duty could be adjusted against the demand for underpayment, subject to computation of the net duty liability.

Issues: (i) whether excess duty paid by the assessee could be adjusted against a demand for short payment of duty; (ii) whether the claim for such adjustment was barred by limitation under the refund provision.

Issue (i): whether excess duty paid by the assessee could be adjusted against a demand for short payment of duty

Analysis: The adjustment mechanism under the central excise rules contemplated reconciliation of duty determined and duty actually paid, with credit for excess payment where the assessed duty was lower. On the facts, the assessee's manufacturing process made both overpayment and underpayment possible during the relevant period, and the department did not dispute that excess payment could have occurred. The view that the assessee must always file a separate claim and that no set-off could be granted would defeat the adjustment scheme under the rules. The department was therefore required to examine both overpayment and underpayment and compute the net duty position.

Conclusion: The assessee was entitled to adjustment of excess duty against any demand for underpayment.

Issue (ii): whether the claim for such adjustment was barred by limitation under the refund provision

Analysis: The limitation objection was rejected because the assessments for the period in question were shown to have been provisional. In that situation, the claim for adjustment could not be treated as a time-barred refund claim under the refund provision, and the department could not refuse set-off on that ground.

Conclusion: The claim for adjustment was not time-barred.

Final Conclusion: The impugned order was set aside and the matter was to be examined for net adjustment of excess and short-paid duty, with consequential relief to the assessee.

Ratio Decidendi: Where the excise rules permit adjustment of duty actually paid against duty assessed, excess payment and short payment must be netted off on the facts of the case, and a provisional assessment prevents the adjustment claim from being defeated as a time-barred refund.
