“It follows in my judgment that it is not enough for a party to assert simply that it has successfully fought allegations of the utmost gravity, regardless of the circumstances in which those allegations came to be made. Although a case in which such allegations are made may for that reason alone be out of the norm, especially a case of the present size and complexity, that is unlikely in itself to constitute a good reason for the award of indemnity costs. To those conclusions on the issues of principle separating the parties I would add this. Whenever the court is asked to make some out-of-the-ordinary costs order in consequence of the alleged misconduct of the party against whom the application is made, the court must bear constantly in mind the conduct of the party making the application. I consider this to be so for two main reasons. The first is that the conduct of the party making the application may have been, in some respect, a contributory cause of the conduct complained about. It may even lead to the conclusion that the conduct complained about, although unsuccessful, was nonetheless not unreasonable in the circumstances.”
