Refund on quantity discount upheld where final assessment was not established and unjust enrichment was not proved.

Refund of duty on quantity discount was maintained where final assessment was not established and the discount was granted at the time of sale, so the provisional assessment requirement for later-ascertainable discounts did not apply. The refund was also not defeated by unjust enrichment because a chartered accountant's certificate and the record showed that the duty incidence had not been passed on to buyers, and Revenue did not rebut that evidence. The order allowing refund was upheld on both grounds.

Issues: (i) Whether the refund claims were barred because the assessments had attained finality and no request for provisional assessment was made; (ii) Whether the refund claims were defeated by the principle of unjust enrichment.

Issue (i): Whether the refund claims were barred because the assessments had attained finality and no request for provisional assessment was made?

Analysis: The assessments were not shown to have been finally made against the respondents by any corroborative order, and the record did not establish that they had accepted a final assessment that required a prior challenge before seeking refund. The quantity discount was granted at the time of sale and was not a case where the discount was unknown at clearance and ascertainable only later. On that factual footing, the administrative instruction requiring provisional assessment for subsequently ascertainable discounts did not apply.

Conclusion: The refund claims were not barred on the ground of final assessment or failure to seek provisional assessment.

Issue (ii): Whether the refund claims were defeated by the principle of unjust enrichment?

Analysis: The respondents produced a chartered accountant's certificate showing that the incidence of duty had not been passed on to the buyers, and the revenue did not dislodge that certificate. The discount was extended at the point of sale without recovery of any corresponding amount from the buyers, supporting the finding that the duty burden had not been transferred.

Conclusion: The refund claims were not hit by unjust enrichment.

Final Conclusion: The order allowing refund was upheld and the Revenue's challenge failed on both grounds.

Ratio Decidendi: A refund cannot be denied on the basis of final assessment or provisional assessment requirements where final assessment is not established and the discount is granted at the time of sale, and the refund is maintainable when unjust enrichment is negatived by unchallenged evidence that the duty burden was not passed on.
