Equity-Based Decision-Making and the Fair and Equitable Treatment Standard: Lessons From the Argentine Investment Disputes – Part I

Abstract

In Part I of this two-part article the author examines the foundations for equity-based decision-making under international law and their relevance to resolving contemporary investment disputes based on the Fair and Equitable Treatment standard (FET standard). He contends that equity-based decision-making in the past has been rare, and in such instances adjudicators have been extremely restrained because of the propensity for subjective judgments. However, in the modern day application of equitable considerations in a large number of investments disputes before the International Centre for Settlement of Investment Disputes (ICSID) seeking relief based on the FET standard, the decisions have mostly been inconsistent and conflicting, leading often to inexplicable and excessive remedies. In no other line of cases has this trend been more demonstrated than in the investment disputes following the Argentine economic crisis. They point more to the serious anomalies and omissions and interpretive issues in International Investment Agreements (mostly BITs) which require remedial measures if international investment law itself is to advance.
