Excise refund claims hinge on limitation, protest payment, and unjust enrichment; later-period refund survives, earlier periods need further findings.

Refund claims in excise matters must be tested on limitation, whether duty was paid under protest, and compliance with the unjust enrichment requirement under Mafatlal Industries. Duty paid on or after 18 July 1981 was treated as paid under protest, so the refund claim for 18 July 1981 to 31 January 1985 was not barred by limitation, subject to the law in Mafatlal and proof that the duty burden had not been passed on. For 1 March 1975 to 11 February 1980, the question of protest was remitted to the original authority for determination. The refund claim for 11 February 1980 to 18 July 1981 was rejected because the duty was not shown to have been paid under protest.

Issues: (i) whether the refund claim for the period July 18, 1981 to January 31, 1985 was barred by limitation, (ii) whether the payment of duty during March 1, 1975 to February 11, 1980 was under protest, and (iii) whether the refund claim for February 11, 1980 to July 18, 1981 was maintainable.

Issue (i): whether the refund claim for the period July 18, 1981 to January 31, 1985 was barred by limitation.

Analysis: The payment made on or after July 18, 1981 was accepted as having been made under protest, and on that basis the claim for the later period was held not to be barred by limitation. The refund, however, was directed to be examined in accordance with the law declared in Mafatlal Industries and the requirement of an affidavit that the duty burden had not been passed on.

Conclusion: The refund claim for July 18, 1981 to January 31, 1985 was not barred by limitation, and the matter was to proceed subject to the law in Mafatlal.

Issue (ii): whether the payment of duty during March 1, 1975 to February 11, 1980 was under protest.

Analysis: For the earlier period, the matter was left for determination by the original authority on the specific question whether the duty had been paid under protest. The subsequent treatment of the claim was made dependent on that finding and, if answered in the affirmative, on the principles laid down in Mafatlal and the format order.

Conclusion: The issue was remanded for determination by the original authority.

Issue (iii): whether the refund claim for February 11, 1980 to July 18, 1981 was maintainable.

Analysis: The record showed that the duty paid during this period was not under protest, and no basis was found to sustain the refund claim for this interval.

Conclusion: The refund claim for February 11, 1980 to July 18, 1981 was rejected.

Final Conclusion: The appeals were disposed of by upholding the claim for the later period as not time-barred, remanding the earlier period for a finding on protest, and rejecting the intermediate period refund claim.

Ratio Decidendi: Refund claims in excise matters must be tested on limitation and on whether duty was paid under protest, and any admissible claim must also satisfy the law on unjust enrichment as declared in Mafatlal Industries.
