​On August 10, 2012, the ICSID Secretariat provided ICSID Contracting States with a report prepared by the Secretariat concerning the ICSID Convention annulment mechanism. This report was prepared as a result of the discussion on annulment at the 2011 Annual Meeting of the ICSID Administrative Council. The report is intended to provide Contracting States with an overview of the annulment remedy and empirical data on annulment to June 30, 2012. It is not intended as legal advice, nor does it take a position on whether any case is correctly decided.

The report can be found here.
