Context:

• Foreign investment inflows are an important indicator of economic attractiveness.
• Bilateral Investment Treaties (BITs) seek to promote such investment by assuring foreign investors a predictable regulatory environment and protection against arbitrary state action.
• However, excessive investor protections can constrain a State’s regulatory autonomy, taxation powers and policy space.
• India’s experience with the Cairn and Vodafone disputes highlights how treaty protections may enable investors to challenge sovereign measures, even when such measures arise from legitimate public-policy objectives.

Investor Protection vs. Sovereign Regulatory Powers:

• BITs commonly provide protections such as -
  • Fair and Equitable Treatment (FET)
  • Protection against expropriation
  • Non-discrimination
  • Protection of investments
  • Investor-State Dispute Settlement (ISDS) through international arbitration
• The concern is that broad standards such as FET may operate asymmetrically.
• Foreign investors can obtain remedies unavailable to domestic investors, while States may have limited reciprocal protection for their tax base and regulatory interests.
• India reviewed its earlier BIT framework in 2016 and subsequently adopted a new Model BIT that seeks to balance investment protection with the State’s right to regulate.

The Expropriation Question:

• Historical episodes such as the nationalisation of Mexico’s oil industry (1938), Cuban expropriations (1959) and post-World War II nationalisation in Europe explain why investors seek protection against arbitrary asset seizure.
• Such safeguards remain relevant because energy and extractive industries account for a significant share of investor-State disputes.
• However, a change in ownership or control of an asset cannot automatically be equated with legitimate public regulation.
• Protection against expropriation must therefore be distinguished from restrictions on policy sovereignty.

Taxation and Forum Shopping:

• What is the problem?
  • Governments have the sovereign power to impose and collect taxes.
  • However, some BITs allow foreign investors to take disputes to international arbitration if they believe a government’s action has unfairly harmed their investment.
  • If taxation disputes are covered by BITs, a foreign company may challenge a tax measure through international arbitration.
  • A domestic company facing the same tax measure generally has to use the domestic legal system.
• Implications: This creates a potential two-tier system of justice (Foreign investor → BIT → International arbitration; Domestic investor → Domestic courts/tribunals).
• What is “forum shopping”?
  • Forum shopping means choosing the legal forum that offers the most favourable route or outcome.
  • This is why some investors have used BITs instead of tax treaties, even when tax treaties provide mechanisms for resolving taxation disputes.
• Why is India concerned?
  • India's position is that taxation is fundamentally a sovereign function.
  • Tax disputes should therefore generally be handled through domestic tax mechanisms or the Mutual Agreement Procedure (MAP) available under tax treaties.
  • The concern is also about equality: foreign investors should not receive a special dispute-resolution mechanism that is unavailable to domestic taxpayers.
• Key takeaway: BITs should not allow foreign investors to bypass domestic tax mechanisms and challenge sovereign taxation decisions through international arbitration.

Alternative Dispute-Resolution Mechanisms:

• India’s approach is not unique. Brazil’s Cooperation and Investment Facilitation Agreements largely avoid ISDS and emphasise State-to-State dispute settlement, Joint committees, Institutional dialogue and dispute prevention.
• For taxation disputes, India can strengthen the MAP under tax treaties, allowing the concerned States to resolve disputes through consultation rather than investor-initiated arbitration.
• Excluding tax matters from BITs is therefore compatible with evolving international practice.

Exhaustion of Domestic Remedies:

• Another contentious issue is whether foreign investors should first exhaust domestic legal remedies before initiating international arbitration.
• India’s recent treaties have attempted to strike a balance. For example, its investment treaty framework with the UAE requires exhaustion of local remedies for a specified period (not longer period) before arbitration.
• However, creating an excessively fast-track system for foreign investors could undermine equality before law and delay justice for domestic investors.

Way Forward: India’s BIT policy should pursue a balanced investment regime based on -

• Predictable and transparent regulations.
• Protection against genuine discrimination and unlawful expropriation.
• Explicit exclusion or careful treatment of taxation disputes.
• Greater use of State-to-State mechanisms and MAP.
• Reasonable exhaustion of domestic remedies.
• Preservation of the right to regulate in public interest.
• Avoidance of nationality-based preferential access to justice.

Conclusion:

• BITs can provide investor confidence, but their value should not be measured merely by the breadth of investor rights.
• Investment protection must coexist with fiscal sovereignty, regulatory autonomy and equal access to justice.
• The debate represents the larger challenge of reconciling globalisation and capital mobility with democratic regulatory sovereignty—a key issue in India’s evolving international economic policy.
