  The Czech Republic (Appellant) v Diag Human SE and another (Respondents) No 2

  Lord Lloyd-Jones,

  Lord Hamblen,

  Lord Leggatt,

  Lord Burrows,

  Lord Doherty

  Does “control” for the purposes of Article 1(1)(c) of the investment treaty agreed between the Czech and Slovak Federal Republic and the Swiss Confederation dated 5 October 1990 (“BIT”) require that the legal entity be controlled de jure, or is de facto control sufficient? What is the test for “de facto” control for the purposes of Article 1(1)(c) BIT? Did the CA err by holding that CR’s objection to Mr Strava’s claim in respect of breaches of the BIT post-dating the alleged disposal of his interest in the qualifying investments was not an objection to “substantive jurisdiction” under section 30 Arbitration Act 1996? Did the Court of Appeal err by ordering that the full BIT award should be paid to Mr Stava despite finding that Diag Human SE was not a qualifying investor for the purposes of the BIT?
