Duty adjustment for same-period excess payment upheld; unjust enrichment rejected and penalties set aside after recomputation

Excess duty and short payment arising from the same SAP-related valuation error could be adjusted against each other, and the refund claim was not barred by unjust enrichment because the excess payment was linked to the actual duty liability for the same period. The demand was not held time-barred, as the extended period was upheld on the facts after the irregularity surfaced in audit. Penalties were set aside because the duty liability required recomputation after giving credit for the excess duty already paid. The matter was remanded for fresh quantification of duty and interest after adjustment.

Issues: (i) whether the demand was barred by limitation and the extended period could be invoked; (ii) whether excess duty paid could be adjusted against short-paid duty and whether the refund claim was hit by unjust enrichment; (iii) whether the penalties imposed were sustainable.

Issue (i): whether the demand was barred by limitation and the extended period could be invoked

Analysis: The short payment and excess payment arose from a SAP-related valuation anomaly noticed during audit. Once the irregularity came to light, the assessee paid the short duty and sought adjustment of the excess duty already paid. On those facts, the allegation of limitation was not accepted.

Conclusion: The demand was not barred by limitation and the extended period was upheld.

Issue (ii): whether excess duty paid could be adjusted against short-paid duty and whether the refund claim was hit by unjust enrichment

Analysis: The excess and short payments related to the same overall period and arose from the same computational error. The adjustment of duty is permitted in law where excess duty and short duty are both established, and the refund was sought for the amount paid in excess of actual liability. In these circumstances, the bar of unjust enrichment was held inapplicable.

Conclusion: The assessee was held entitled to adjustment of the excess duty paid against the short-paid duty, and the refund was not liable to be rejected on unjust enrichment.

Issue (iii): whether the penalties imposed were sustainable

Analysis: Since the duty position required recomputation after giving credit for the excess duty already paid, the penalties imposed on the original duty and refund findings could not be sustained on the order as framed.

Conclusion: The penalties were set aside.

Final Conclusion: The appeals were allowed in part in favour of the assessee on the adjustment and penalty issues, while the matter was remanded for fresh quantification of duty and interest after adjustment of excess duty already paid.

Ratio Decidendi: Where excess duty and short duty arise from the same period and the excess payment is demonstrably linked to the duty liability, adjustment of the excess against the short payment is permissible, and a refund of the excess cannot be denied on unjust enrichment when the liability is required to be recomputed on that basis.
