Event Details

BIICL and White & Case are delighted to present our 2023 comprehensive empirical study on provisional measures in investment treaty arbitration. It builds up on success of the 2019 empirical study, which has now been extensively cited in academic literature, and decisions of arbitral tribunals and parties' submissions on provisional measures.

This study conducts a detailed examination of 160 decisions on provisional measures, including 46 new publicly available decisions, and how these decisions affect and change the trends and practices, identified in our 2019 study.

These new decisions provide more clarity on the criteria used by tribunals to grant provisional measures and their understanding of such criteria, success rate by applicable arbitration rules and measures requested as well as the cases most frequently relied upon by international tribunals. The study also deals with some of most crucial issues facing investment arbitration at the moment, including the fate of the intra-EU investor-State disputes, and the sanctions against Russia.

For the first time, this study explores procedural aspects and procedural efficiency of the decisions on provisional measures, including the average number of days it takes for the tribunals to issue the decisions on the provisional measures, and how it is affected by the arbitration rules, the party making a request, and various procedural factors.

The study further investigates tribunals' decisions on costs, and some of the most recent trends, including the increasing use of the "most provisional" decisions on provisional measures by ICSID tribunals, and recent amendments to the ICSID and ICSID Additional Facility Rules.
