Excess duty credit under Rule 173-I(2) allowed where assessed duty was lower than duty paid under approved classification

Where RT 12 returns were assessed in accordance with an approved classification list and the assessed duty was lower than the duty paid, Rule 173-I(2) entitled the assessee to credit the excess duty in the account current. The rule was treated as distinct from a refund claim under Section 11B and was held not to be limited to clerical errors or dependent on any express direction in the assessment memorandum. On that basis, the challenge to the assessee's suo motu credit failed, and the appeal was dismissed.

Issues: Whether, on an assessment under Rule 173-I(2), the assessee could take credit of excess duty paid suo motu, and whether such credit was barred by Section 11B and the doctrine of unjust enrichment.

Analysis: The approved classification list granted exemption, and the RT 12 assessment was completed by the proper officer accordingly. On a plain reading of Rule 173-I(2), where the duty assessed is less than the duty paid, the assessee is entitled to take credit of the excess in the account current. The rule is not confined to clerical mistakes, and it does not require any express direction in the assessment memorandum. The scope of this rule is distinct from a refund claim under Section 11B, which operates in a wider field and does not displace the assessee's entitlement to credit under a valid assessment made within the approved classification framework.

Conclusion: The assessee was entitled to take credit of the excess duty under Rule 173-I(2), and the appeal challenging that entitlement failed. The appeal was dismissed in favour of the assessee.

Ratio Decidendi: Where a proper officer assesses RT 12 returns in accordance with an approved classification list and the assessed duty is lower than the duty paid, Rule 173-I(2) permits the assessee to credit the excess without requiring a separate refund under Section 11B.
