The future of a High Court battle in which the Canada Trust Company is suing Wolfgang Stolzenberg president and chief executive of the Castor Group over alleged malpractice and fraud is to be decided by the House of Lords. Stolzenberg is fighting a long-running battle to block action in the English courts claiming he is outside the jurisdiction of the English High Court. However, in the High Court in 1997 Mr Justice Rattee dismissed his application to have the case struck out and last year the Court of Appeal upheld that decision. Now the House of Lords has given leave for appeal against these two rulings. The action itself centres on a series of investments amounting to Canadian dollars $240m.
