‘[47] The judge directed himself by asking two questions: (a) “Is it an abuse of process for the claimant to seek to litigate in the present action the same issues which were raised, but not adjudicated upon, in the first action which was struck out?” (b) “If the answer to (a) is ‘yes’, should I, in the exercise of my discretion, nevertheless allow the action to proceed?” Having answered the first of those two questions “yes”, he approached the exercise of his discretion in this way: “In order to exercise my discretion so as not to strike out the present action, some special reason needs to be identified which, having regard to the overriding objective, would mean that it was just to allow the present action to proceed.” [48] The learned judge was entitled to adopt the approach that he did … [49] I should say a word or two about his reference to “some special reason”. The use of these words is an attractive form of forensic shorthand which encapsulates the broad approach to the decision-making process to be adopted when an action has failed as a result of an abuse of process and the court is considering whether a second action relating to the same issues should be allowed to continue. The words come from authority binding on this court: Arbuthnot Latham Bank Ltd v Trafalgar Holdings Ltd[1998] 1 WLR 1426 ; but they are not words which derive from the statute, nor from the Civil Procedure Rules, and they should not be treated as if they had. Nor should they be employed as some form of ritual incantation. If the judge in this case had chosen to express the same principle by saying “very good reason”, or “powerful” or “sufficient reason”, he would not, in my judgment, have misdirected himself.’
