Court Finds Procedural Lapses and Misinterpretation of Contractual Clauses in GST Reimbursement Case
In a significant ruling on July 23, 2026, the Delhi High Court quashed an arbitration award that had dismissed the claims of Spectrum Power Generation Limited against Gail India Limited concerning the reimbursement of Goods and Services Tax (GST). The court found multiple procedural deficiencies and misinterpretations of contractual terms in the arbitration tribunal's decision.
The dispute arose from a Gas Sale Agreement (GSA) between Spectrum Power Generation Limited, which operates a natural gas-based power plant, and Gail India Limited, a supplier of natural gas. The controversy began after the implementation of the GST regime, with Gail India raising invoices for GST reimbursement on natural gas transmission charges, which Spectrum contested.
Justice Avneesh Jhingan, presiding over the case, noted that the tribunal had overstepped by relying on evidence whose admissibility was contested and not decided, violating principles of natural justice. The court emphasized that the tribunal erred by not addressing Spectrum's objections to the GST deposit receipts, which were critical to the case. This oversight, the court held, constituted a serious procedural lapse.
The judgment further analyzed the contractual interpretations made by the tribunal. It was highlighted that the tribunal incorrectly invoked principles of estoppel and waiver, ruling that Spectrum had waived its rights and was estopped from contesting the GST payments after having reimbursed them for several years. The court clarified that for waiver and estoppel to apply, clear evidence of intentional relinquishment of rights and reliance by the other party must be present, which was not demonstrated in this case.
Moreover, the court criticized the tribunal's decision to dismiss Spectrum's entire claim based on procedural clauses without considering the recurring nature of the contractual obligations and the continuing cause of action with each invoice.
Concluding the judgment, Justice Jhingan set aside the arbitration award, reinstating Spectrum's claims and highlighting the importance of procedural fairness and accurate contractual interpretation in arbitration proceedings.
Bottom line:-
Arbitration and Conciliation Act, 1996 - Scope of interference under Section 34 is limited - Interpretation of contractual clauses primarily falls within the domain of the arbitral tribunal unless the interpretation is perverse or ignores the terms of the contract.
