Refund claims must rest on section 11B facts, not another case's ruling, and duty incidence must be examined.

Refund cannot be claimed merely on the strength of a decision rendered in another party's case, because the Mafatlal Industries embargo prevents reopening of refund claims on that basis alone. The benefit of Ram Body Builders did not automatically extend to respondents who were not parties to that litigation, and the claim was rejected on that point. Entitlement to refund under section 11B also depends on factual inquiry into whether the assessment was final or provisional and whether the incidence of duty had been passed on. Those matters required fresh determination by the original authority, so the refund issue was remitted for de novo consideration.

Issues: (i) Whether refund claims based on the decision in Ram Body Builders could be granted as a matter of course to the respondents who were not parties to that decision. (ii) Whether the question of passing on the incidence of duty and finality of assessment had to be examined on facts before refund could be considered under section 11B.

Issue (i): Whether refund claims based on the decision in Ram Body Builders could be granted as a matter of course to the respondents who were not parties to that decision.

Analysis: The embargo stated in Mafatlal Industries applied, because a refund claim cannot be reopened merely by relying on a decision rendered in another person's case. The benefit of the earlier decision could not automatically extend to respondents who were not covered by that litigation.

Conclusion: The issue was decided against the assessees and in favour of the Revenue.

Issue (ii): Whether the question of passing on the incidence of duty and finality of assessment had to be examined on facts before refund could be considered under section 11B.

Analysis: The question whether assessments were provisional or final, and whether the duty burden had been passed on, was a factual matter requiring determination by the original authority. The Tribunal held that such facts could not be conclusively decided at the appellate stage on the material before it, and refund would depend on the outcome of that inquiry under section 11B.

Conclusion: The issue was left for fresh factual determination, resulting in remand in favour of the Revenue.

Final Conclusion: The refund orders were set aside and the matters were remitted to the original authority for de novo consideration, with refund to be examined afresh on the relevant facts and statutory requirements.

Ratio Decidendi: Refund cannot be claimed merely on the strength of a decision in another case, and the entitlement to refund must be tested on the factual questions of finality of assessment and passing on of duty under section 11B.
