Remand power in refund disputes cannot reopen a concluded nexus finding; only quantification may be reconsidered.

An appellate authority cannot use remand to reopen an issue already concluded on merits; here, the Commissioner (Appeals) lacked power to remand the matter on the nexus question, and that part of the order was liable to be set aside. The nexus between the exported output service and the input services had already been decided in favour of the claimant for refund under Rule 5 of the CENVAT Credit Rules, 2004, so the Chartered Accountant's certificate could be used only for quantification of the refundable amount and not for reconsidering the settled nexus. The matter was therefore remitted only for limited quantification, leaving the nexus finding undisturbed.

Issues: (i) Whether the Commissioner (Appeals) had power to remand the matter to the original authority; (ii) whether the nexus between the exported output service and the input services stood finally decided for the purpose of refund under Rule 5 of the CENVAT Credit Rules, 2004, with only quantification left for reconsideration.

Issue (i): Whether the Commissioner (Appeals) had power to remand the matter to the original authority.

Analysis: The appellate authority relied on a Chartered Accountant's certificate and directed reconsideration by the original authority on the nexus aspect. The governing legal position, as reflected in the reasoning, was that the appellate authority could not retain or exercise a general power of remand in the manner done here.

Conclusion: The Commissioner (Appeals) had no such power of remand and his order was liable to be set aside on that ground.

Issue (ii): Whether the nexus between the exported output service and the input services stood finally decided for the purpose of refund under Rule 5 of the CENVAT Credit Rules, 2004, with only quantification left for reconsideration.

Analysis: The finding was that the input services were connected with export of taxable service and the nexus issue had already been settled by the appellate authority. The Chartered Accountant's certificate contemplated by the Board's circular was relevant only for quantifying the refundable amount and not for reopening the concluded nexus determination.

Conclusion: The nexus issue stood decided in favour of the claimant, and the matter could be sent back only for limited quantification of refund.

Final Conclusion: The appellate order was set aside, and the matter was remitted only for quantification of the refund amount while leaving the nexus determination undisturbed.

Ratio Decidendi: An appellate authority cannot use remand to reopen an issue already concluded on merits, and a certificate-based procedure may be directed only for the limited purpose for which it is intended.
