Supreme Court’s Verdict on Pre‑Award Interest in Arbitration The Supreme Court of India has clarified that an Arbitral Tribunal cannot award pre‑award interest or pendente lite interest if the underlying contract expressly forbids it. The decision arose from a dispute involving Larsen & Tubro Limited (L&T) and the Union of India over a railway modernization project. Key Developments The Supreme Court set aside the Allahabad High Court’s order that had upheld the award of pre‑award interest despite a contractual bar. It reaffirmed that under Section 37(1)(a) of the Arbitration & Conciliation Act, 1996 , interest cannot be imposed contrary to contract terms. The Court upheld the award of post‑award interest but reduced the rate from 12% to 8% per annum. The judgment emphasized compliance with the GCC clauses 16(3) and 64(5), which barred any interest before the award. Important Facts of the Case The dispute originated from a 2011 turnkey contract worth approximately ₹93.08 crore for modernising the North Central Railway’s Jhansi Workshop. Delays of 40 months led L&T to seek arbitration for unpaid dues, price escalations, and financing charges. In 2018, the Arbitral Tribunal awarded L&T ₹5.53 crore , but despite the explicit prohibition in Clause 64(5) of the contract, it granted interest‑like amounts for Claims 1, 3, and 6, labeling them as “compensation.” Both the Commercial Court and the Allahabad High Court upheld this award, prompting the Union of India to appeal. UPSC Relevance This judgment is significant for several UPSC topics: Legal Framework (GS2) : Illustrates the hierarchy of statutes, contractual autonomy, and the limited scope of judicial intervention under Section 31(7)(a) . Economic Implications (GS3) : Highlights how interest calculations affect large infrastructure projects and the fiscal exposure of the exchequer. Governance and Policy (GS1/GS4) : Demonstrates the importance of adhering to contractual clauses in public‑private partnerships, reinforcing transparency and accountability. Way Forward Legal practitioners and contracting authorities should: Draft contracts with clear, unambiguous clauses on interest, specifying whether pre‑award or post‑award interest is permissible. Ensure arbitral tribunals are aware of statutory limits, particularly Section 37(1)(a) , to avoid award reversals. Monitor post‑award interest rates and align them with prevailing market rates to prevent undue financial burden on the government. Overall, the Supreme Court’s decision reinforces contractual sanctity in arbitration and provides a clear precedent for future disputes involving interest awards.
