The United Nations Conference on Trade and Development (UNCTAD) has completed its regular semi-annual update of the Investment Dispute Settlement Navigator (updated as of 1 January 2017). In 2016, investors initiated 62 known investment cases pursuant to international investment agreements (IIAs). This number is lower than in the preceding year (74 cases in 2015), but higher than the 10-year average of 49 cases (2006-2015). The Energy Charter Treaty (ECT) continues to be the most frequently invoked investment agreement with 10 cases. Since 2001, when the first case invoking ECT was registered, the Energy Charter Secretariat tracked 101 publicly known investment arbitration cases where the ECT was invoked (sometimes together with a BIT).
Information about the claims has been compiled on the basis of public sources, including specialized reporting services. As arbitrations can be kept confidential under certain circumstances, the actual number of disputes filed in this and previous years is likely to be higher. We welcome any additional information or clarifications on specific cases (firstname.lastname@example.org).
