As of 18/12/2019 there are 128 publicly known investment arbitration cases under the ECT (sometimes invoked together with a bilateral investment agreement). A full list with information is available here.
Since parties to an investment arbitration under Article 26 ECT are not obliged to notify the Secretariat of the existence or substance of their dispute, some awards (and even the existence of some proceedings) remain confidential. The Secretariat compiles information (which cannot be considered as exhaustive) from delegates and public sources (including specialised reporting services such as Global Arbitration Review (GAR), Investment Arbitration Reporter (IAReporter) and ItaLaw). The Secretariat assumes no responsibility for eventual errors or omissions in these data and welcomes any additional information or clarification on specific cases (at email@example.com or using the online contact form).
