The United Nations Conference on Trade and Development (UNCTAD) has recently published a report on developments of ISDS in 2015. The report addresses ISDS cases initiated in 2015 as well as the statistics on overall ISDS cases from 1987 to 2015.
The report finds that there were 70 ISDS cases initiated in 2015, which brings an overall number of publicly known ISDS cases to 696. Most of the cases initiated in 2015 arose from old bilateral investment treaties dating back in the 1990s.
Investors from developed countries made the most frequent claimants in cases initiated in 2015, with the top three home states of investors being the United Kingdom, Germany and Luxembourg. This is also true when it comes to the home states of claimants in total since 1987, where investors from the United States, the Netherlands and the United Kingdom top the list.
On the state side, Spain was the most frequent respondent state in cases initiated in 2015, followed by Russia, Czech Republic and Ukraine. Overall since 1987, most frequent respondent states in ISDS cases are still developing countries, with Argentina and Venezuela top the list.
As for the matters being disputed, a number of cases initiated in 2015 concerned sustainable development sectors such as infrastructure and climate change mitigation. Approximately 30% of cases were triggered by the regulation of renewable energy producers, all of which were brought against EU member States (Bulgaria, Italy, and Spain).
ISDS tribunals rendered at least 51 decisions in 2015, 31 of which were in the public domain at the time of the writing of the report. This brings the number of concluded cases to 444 by the end of 2015, with 36% of the cases decided in favour of the State, 26% in favour of investors and 26% cases were settled.
