The respondents rely in particular on the concluding remarks from that passage of Nourse LJ's judgment [in Re Elgindata Ltd (No 2)[128]]. The Court of Appeal were indicating the then approach, recognised by the authorities, adopted by the courts as a matter of practice. The practice of the courts does evolve, and in recent times there has been a greater emphasis on recognising that the raising of issues in the course of complex litigation, of which this case can be considered as an example, can increase the costs of that litigation. It is therefore important that the parties should pay careful attention to the merits, not only of the whole case but to the issues which arise in the course of a case. In complex litigation, where issues are raised on which a party is unsuccessful, the court should, when appropriate, make orders for costs which reflect the fact that, whereas a party may generally be successful, in regard to some of those issues that party has been unsuccessful. Furthermore, if the way in which an issue is conducted or argued has the result of increasing the costs of the litigation, and the court finds that it was unnecessary for the party to develop the issue in that way, that again can be reflected in a special order for costs.
