Telecom Supplier's Refund Claim Denied for Duty on Software; Unjust Enrichment Not Proven

The appellant, a supplier of Telecom equipment, filed a refund application for duty paid on software supplied to MTNL/BSNL. The court held that duty was correctly paid as the value of software was included in the assessable value. Despite the Original Authority finding that the value of software is not includable in the assessable value, the appellant failed to prove unjust enrichment. The First Appellate Authority upheld the rejection of the refund claim due to lack of evidence that duty incidence was not passed on to customers. The appeal was dismissed, affirming the denial of the refund claim.

ISSUES PRESENTED AND CONSIDERED

1. Whether the refund claim of duty paid on software supplied with telecom hardware is barred by the principle of unjust enrichment where invoices show duty separately.

2. Whether a Chartered Accountant's certificate stating duty paid and that the supplier did not recover any amount "over and above the value of software" suffices to discharge the onus of proving that the incidence of duty was not passed on to the buyer.

3. What evidentiary value attaches to statutory invoices (issued under the relevant excise provision) that separately show the duty element, in determining whether the supplier passed the incidence of duty to the customer.

ISSUE-WISE DETAILED ANALYSIS

Issue 1 - Bar of unjust enrichment where invoices show duty separately

Legal framework: Refund of erroneously paid duty is subject to the proviso against unjust enrichment - the claimant must prove that the incidence of duty was borne by it and not passed on to the buyer. Invoices and accounting records are material to this enquiry.

Precedent treatment: The Court relied upon the principle from higher authority that when the duty element is separately shown in invoices, it may be inferred that the supplier passed the incidence of duty to the customer.

Interpretation and reasoning: The contractual documents (purchase orders) showed prices inclusive of taxes and itemised a software value per unit, with at least one purchase order expressly indicating 0% tax on software. The invoices examined showed a combined value for hardware and software with a separately stated excise duty amount. The Tribunal found no contemporaneous documentary indication that the duty component shown in the invoices was not recovered from the buyer or that the duty was treated as an expense in profit and loss account. Given the statutory nature of invoices and the explicit separate disclosure of duty, the Court considered it reasonable to infer that the incidence of duty was passed on to the customers.

Ratio vs. Obiter: Ratio - where invoices issued under statutory provisions display a separate duty element and there is no corroborative accounting evidence showing that duty was absorbed by the supplier, the refund claim is vulnerable to rejection on unjust enrichment grounds.

Conclusion: The refund claim is barred by unjust enrichment because the invoices sufficiently indicate that the incidence of duty was passed to the purchasers and no adequate accounting evidence was produced to rebut that inference.

Issue 2 - Sufficiency of Chartered Accountant's certificate to prove non-passing of incidence

Legal framework: An applicant for refund must demonstrate by contemporaneous and cogent evidence how the duty was treated in its books to show the burden was not passed on; mere statements about duty paid are not automatically conclusive.

Precedent treatment: The Court applied established evidentiary principles that require more than a certificate of payment; the certificate must be supported by accounting entries or other documentary proof showing that the duty was charged to expense and not recovered from buyers.

Interpretation and reasoning: The Chartered Accountant's certificate relied on by the claimant stated that duty on software was paid and that the claimant recovered "the total value of software and not recovered any amount over and above the value of software as indicated in the certificate." The Court noted the certificate did not explain how the duty amount was treated in the books of account (e.g., charged to Profit & Loss Account) and was therefore silent on the critical fact necessary to displace the presumption of passing on. In absence of ledger entries, journal vouchers, or profit-and-loss treatment demonstrating absorption of duty, the certificate was insufficient.

Ratio vs. Obiter: Ratio - a certificate merely recording payment of duty and a statement about recovery of software value does not, by itself, discharge the onus to prove non-passing of duty; accounting records demonstrating treatment of duty are required.

Conclusion: The CA certificate was insufficient to prove that the supplier bore the incidence of duty; thus it could not overcome the inference of passing-on arising from the invoices.

Issue 3 - Evidentiary weight of statutory invoices showing duty separately

Legal framework: Statutory invoices issued under excise law are important evidence; separate disclosure of duty in invoices can be treated as indicia that the supplier intended the buyer to bear the duty element.

Precedent treatment: The Court followed binding authority that where duty is separately shown in invoices, it is permissible to infer that the supplier passed on the duty to the buyer, absent evidence to the contrary.

Interpretation and reasoning: The invoices before the Court displayed a consolidated value for goods and software along with a separately stated duty amount. The Court observed that statutory invoices are not neutral in this context - separate disclosure of duty serves not merely for compliance but signals to the buyer the duty component. Without accompanying accounting proof that the duty was absorbed by the supplier (for example, entries showing duty debited to expense and not recovered), the invoice disclosure supports the conclusion of passing-on.

Ratio vs. Obiter: Ratio - statutory invoices that separately disclose duty create a strong presumption of passing-on; this presumption stands unless rebutted by clear accounting evidence that the supplier bore the duty.

Conclusion: The invoices had significant probative value and, in absence of explanatory accounting evidence, justified rejecting the refund claim on unjust enrichment grounds.

Interrelationship and procedural remand observations

Legal framework: Where appellate authority remands for factual verification (e.g., nature of software, unjust enrichment), the original authority must examine and record specific evidence on whether duty incidence was passed on or absorbed.

Interpretation and reasoning: Although a remand was earlier directed to examine nature of software and unjust enrichment, the remand finding concluded software value not includable in assessable value but still found no proof of non-passing of duty. The Court reviewed both contractual terms and invoicing and found no documentary treatment demonstrating absorption of duty; thus the remand did not produce evidence sufficient to alter the unjust enrichment conclusion.

Ratio vs. Obiter: Ratio - a remand that yields findings adverse to a refund claim must be supported by documentary proof; absence of such proof validates the finding rejecting refund on unjust enrichment.

Conclusion: The remand proceedings did not produce requisite accounting or documentary evidence to rebut the presumption of passing-on; the finding rejecting refund was thus sustained.

Overall Conclusion and Disposition

Applying the legal framework and controlling authority, the Court concluded that the claimant failed to discharge the burden of proving that the incidence of duty was not passed to the purchasers. The statutory invoices showing duty separately, coupled with absence of accounting evidence demonstrating absorption of duty, warranted dismissal of the refund claim on the ground of unjust enrichment.
