“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”
“Where, however, the non-party not merely funds the proceedings but substantially also controls or at any rate is to benefit from them, justice will ordinarily require that, if the proceedings fail, he will pay the successful party's costs. The non-party in these cases is not so much facilitating access to justice by the party funded as himself gaining access to justice for his own purposes. He himself is ‘the real party’ to the litigation, a concept repeatedly invoked throughout the jurisprudence”
“The procedure for the determination of costs is a summary procedure, not necessarily subject to all the rules that would apply in an action. Thus, subject to any relevant statutory exceptions, judicial findings are inadmissible as evidence of the facts upon which they were based in proceedings between one of the parties to the original proceedings and a stranger. Yet, in the summary procedure for the determination of the liability of a solicitor to pay the costs of an action to which he was not a party, the judge’s findings of fact may be admissible. This departure from basic principles can only be justified if the connection of the non-party with the original proceedings was so close that he will not suffer any injustice by allowing this exception to the general rule”
“If this is the first time that an order is made and, as a result, orders will be sought on other occasions, that does not open too wide a floodgate, because I accompany it, and I am sure any other judge would accompany it with a substantial reminder that the procedure is ordinarily summary and that the procedure is ordinarily intended to reflect all the caveats which the s.51 jurisprudence in the reported cases are set out for us to bear in mind: (i) These are ancillary proceedings and should not grow out of control into satellite litigation. (ii) Proportionality must always be considered. (iii) It must always be borne in mind that the ordinary process is a summary process”
“Equally, however, it must be borne in mind that the issues in the satellite litigation will be issues which may well not have been resolved in the main action; whether a party was a funder, whether a party was controlling proceedings may well not have featured in the main action. If the only fair way in which those issues can be resolved is by the making of an order for oral evidence, then, bearing in mind the exceptional nature of the jurisdiction, such an order should be made. I have no doubt at all that there is no jurisdiction to prevent me from making such an order and I have jurisdiction to make it”
