“38. The claimants seek an order that Mr Wojakovski be debarred from defending and/or prosecuting all of the three related actions. Mr Haque QC contends that Mr Wojakovski cannot be debarred from defending the Shares Claim because the costs order was made in the other actions and there is no power to debar a party from defending one action by reason of non-payment of a costs award in another action.” “39. Neither party was able to locate any authority on this point but as a matter of principle it seems to me that Mr Haque’s general proposition is correct. Mr Fulton did not seek to persuade me otherwise, but contended, first, that the costs order was made in respect of all three actions and, second, that in any event the three actions are so closely related that it is artificial to treat them as separate actions.”
