In January 2017, following a series of critical reports on "Caviar diplomacy" by the European Stability Initiative (ESI) NGO, and concern expressed by many members of the Assembly, the Assembly's Bureau decided to set up an independent, external body to investigate these allegations of corruption. In May 2017, three distinguished former judges were named to conduct the investigation: Sir Nicolas Bratza, a British former President of the European Court of Human Rights; Jean-Louis Bruguière, a French former anti-terrorist judge and investigator; and Elisabet Fura, a former Swedish parliamentary Ombudsman and judge on the Strasbourg Court. There are no other known examples in recent history of an international organisation setting up an independent, external anti-corruption probe into itself.
