This paper critically discusses the issue of enforceability of investment treaty arbitration (ITA) awards against India under the Indian domestic law on arbitration. In this regard, the paper discusses the relevant provisions of the Indian arbitration law and its interpretations by the Indian judiciary to understand their ramifications for the enforcement of ITA awards against India. The paper also discusses the proposed amendments to the Indian arbitration law and its ramifications on ITA. The issue of enforcement of ITA awards in India has become important due to India's gigantic international investment treaty programme where each treaty allows for investor-state treaty arbitration to settle disputes between investors and India. This issue has also become important in light of the growing observation that enforcement of foreign commercial arbitral awards in India is extremely difficult especially after the Venture Global engineering case. Thus, India is endeavouring to change the arbitration law so as to alter this perception. This paper argues that in spite of these proposed changes; enforcement of ITA awards may still face problems. Thus, the paper suggests that India should address the issue of enforceability of ITA awards given its gigantic investment treaty programme aimed at attracting foreign investment.
