“Although costs orders against non-parties are to be regarded as “exceptional”, exceptional in this context means no more than outside the ordinary run of cases where parties pursue or defend claims for their own benefit and at their own expense. The ultimate question in any such “exceptional” case is whether in all the circumstances it is just to make the order. It must be recognised that this is inevitably to some extent a fact-specific jurisdiction and that there will often be a number of different considerations in play, some militating in favour of an order, some against.”
“These principles have been applied in a number of subsequent cases, but it is unnecessary to consider them in detail because they all turn to a greater or lesser degree on their own facts. When an order for costs is sought against a third party, the critical factor in each case is the nature and degree of his connection with the proceedings, since that will ultimately determine whether it is appropriate to adopt a summary procedure of the kind envisaged in the authorities, leading to what Neuberger L.J. in Gray v Going Places Leisure Travel Ltd[2005] EWCA Civ 189 described as "the overall order made by the court at the conclusion of the trial." It is important to note, however, that, contrary to Mr. Cogley's submission, the guidance given in Symphony v Hodgson[1994] QB 179 has not been regarded as immutable, but has been developed and modified in subsequent cases to reflect the differing circumstances under which applications for orders of this kind have been made.”
