Lord Justices Rix Longmore and Davis gave judgment on 27 June 2012 and used the opportunity to review and reformulate the law concerning the Act of State Doctrine.
The review began with Lord Justice Russell in the case of Princess Paley Olga v. Weisz  1KB 718 who stated that, “ This Court will not inquire into the legality of acts done by a foreign government against its own subjects in respect of property situate in its own territory.”
