2 Before dealing with this specific application, I would observe that both I and the other members of this Court are firmly of the view that interlocutory disputes of this kind must be actively discouraged. In many cases, interlocutory disputes, particularly disputes relating to pleading issues, consume very substantial amounts of time and expense on the part of both the parties and the Court. In many cases, the time and expense involved in the consideration and resolution of the interlocutory dispute is entirely disproportionate to its significance to the just and effective resolution of the case as a whole by mediation or trial. For this reason, this Court will use the existing powers available under the Rules of the Supreme Court ("the Rules") and if necessary amend the Rules to actively discourage disputes of this kind. In very general terms, interlocutory disputes of this kind will only be entertained by the Court if the time and expense involved in their resolution is proportionate to the significance of the dispute to the just and effective resolution of the case. This principle is, in my view, already inherent in the provisions of the Rules when read as a whole, including in particular O 1 r 4A and r 4B, O 29 and O 29A.
