Stone Sweet, Chung, & Saltzman: Arbitral Lawmaking and State Power: An Empirical Analysis of Investment Arbitration

Alec Stone Sweet (National Univ. of Singapore - Law), Michael Chung, & Adam Saltzman have posted Arbitral Lawmaking and State Power: An Empirical Analysis of Investment Arbitration. Here's the abstract:
The paper focuses on arbitral lawmaking (the development of precedent-based frameworks of argumentation and justification), and state responses to that lawmaking (as registered in subsequent treaty-making). We compiled and analyzed information on: (i) all publicly-available awards (n=159) in which tribunals resolved disputes under the headings of expropriation and fair and equitable treatment, and under an umbrella clause; and (ii) investment treaties signed between 2002 and 2015 (n=398), when available in English. The paper reports three main findings. First, in most disputes, investors do not challenge general state measures; when they do, they are far less to prevail than when they contest acts specifically targeting their investments. Second, the evidence does not support the view that arbitral doctrine produces outcomes that are biased against states. In the vast majority of awards, tribunals take seriously the respondent state’s ‘right to regulate’ in the public interest. Third, the regime has not generated strong ‘backlash’ in any systemic sense. States continue to sign investment treaties; the mix of treaty protections on offer has remained remarkably stable; and new treaties have largely consolidated the case law that the most influential tribunals had already developed.
