ICSID..
Thanks to Jus Mundi for some information at least re their link below to BSKO case details. Still nothing reported from ICSID on the 'result'. Paucity of information almost from inception despite the supposed pledge from ICSID for openness re reporting on cases. What's available so far would appear to be first processed for publication via and would do credit to a secret service, the % that is blacked out or 'redacted' in the various documents available so far ludicrous. At least the initial claimant filing did refer to the subsequent sale of the asset for circa $340m to the Chinese.
