India may restart bilateral investment treaty talks with UK as model text nears finalisation

India's move to finalize its model Bilateral Investment Treaty (BIT) text for renewed negotiations with the United Kingdom marks a significant recalibration in its international investment policy framework. To understand the gravity of this development, we must first appreciate the historical context. India's tryst with BITs began in the 1990s as part of its post-liberalization strategy to attract foreign capital. The country signed its first BIT with the UK in 1994, which remained in force until 2017 when India unilaterally terminated 58 such treaties, including the one with the UK, citing concerns over "treaty shopping" and adverse arbitral awards in cases like White Industries v. India and Vodafone v. India. The termination was executed under Article 12 of the India-UK BIT, which allowed either party to terminate the treaty with one year's notice. This bold move signaled India's dissatisfaction with the existing investor-state dispute settlement (ISDS) mechanism, which it perceived as undermining sovereign regulatory space. The current revival of talks stems from multiple converging factors. Post-Brexit, the UK has been aggressively pursuing independent trade and investment agreements, and India represents a massive market opportunity. Simultaneously, India's ambition to become a $5 trillion economy requires substantial foreign direct investment (FDI), particularly in infrastructure, green energy, and technology sectors. The 2021 launch of India-UK Free Trade Agreement (FTA) negotiations created a natural platform for parallel BIT discussions. The new model BIT, under finalization by the Department of Economic Affairs (DEA) under the Ministry of Finance, incorporates lessons from India's 2016 Model BIT text — which itself was a paradigm shift from the 2003 version. Key innovations in the 2016 model include: (a) narrowing the definition of investment to exclude portfolio investments, (b) introducing an exhaustive list of treaty breaches (denial of justice, fundamental breach of due process, targeted discrimination, and manifest arbitrariness), (c) mandating exhaustion of local remedies before international arbitration, and (d) excluding taxation measures from the treaty's purview — a direct response to the Vodafone retrospective tax controversy. Stakeholders in this negotiation are multifaceted. On the Indian side, the Ministry of Finance (DEA), Ministry of Commerce & Industry, Ministry of External Affairs, and NITI Aayog are key architects. The Cabinet Committee on Economic Affairs (CCEA) will provide final approval. For the UK, the Department for Business and Trade (DBT) leads negotiations. British investors, particularly in financial services, pharmaceuticals, and renewable energy, are keen beneficiaries. Indian industry bodies like CII and FICCI have advocated for a balanced treaty that protects genuine investments while preserving policy space. Civil society groups, however, remain wary of ISDS provisions that could constrain regulatory autonomy in areas like public health, environment, and labor rights. The significance for India is profound. Economically, a modern BIT with the UK — India's 7th largest trading partner (bilateral trade $20.36 billion in FY23) and a major source of FDI ($32.3 billion cumulative, 2000-2023) — can unlock capital for National Infrastructure Pipeline (NIP) projects and Green Hydrogen Mission targets. Politically, it strengthens the "Comprehensive Strategic Partnership" declared in 2021 and supports India's G20 presidency legacy of reforming global governance. Constitutionally, Article 253 empowers Parliament to implement international treaties, while Article 73 extends executive power to matters within Parliament's legislative competence. The treaty must also align with the Arbitration and Conciliation Act, 1996 (amended 2015, 2019, 2021) which governs enforcement of foreign arbitral awards under the New York Convention. Broader themes emerge: India's evolving approach to international law — from passive recipient to active shaper; the tension between investment protection and regulatory sovereignty (a core debate in international economic law); and the geopolitics of rule-setting in the Indo-Pacific. Future implications include potential template effects on BIT negotiations with EU, Canada, and other partners; possible integration with the India-UK FTA's investment chapter; and the critical test of whether the new ISDS mechanism — likely featuring a permanent appellate body and transparency rules — can avoid the pitfalls of the past. For aspirants, this case study encapsulates the dynamic interplay of law, economics, and diplomacy in contemporary Indian statecraft.
