"[Counsel for the plaintiff's] contention was that the defendant solicitors knew where the moneys that they received came from and knew that the source was trust funds. In my view this contention fails at the outset. What the defendant solicitors knew was that the moneys came from the West German foundation and they knew of the allegations contained in the proceedings brought against that foundation by the plaintiffs in which they were instructed to act as solicitors for the West German foundation. They knew that claims were being made against the West German foundation that all their property and assets belonged to the plaintiffs or were held on trust for them. But claims are not the same thing as facts. [The plaintiffs' counsel] contended that for the purposes of the present issue all the allegations contained in the statements of claim in both the actions must be taken as true. That will not do. What we have to deal with is the state of the defendant solicitors' knowledge (actual or imputed) at the date when they received payments of their costs and disbursements. At that date they cannot have had more than knowledge of the claims above mentioned. It was not possible for them to know whether they were well-founded or not. The claims depended upon most complicated facts still to be proved or disproved, and very difficult questions of German and English law. It is not a case where the West German foundation were holding property upon any express trust. They were denying the existence of any trust or any right of property in the assets claimed by the plaintiffs. Why should the solicitors of the West German foundation assume anything against their clients?"
"Firstly, and to my mind decisively, whatever be the nature of the knowledge or notice required, cognisance of what has been termed 'a doubtful equity' is not enough. This phrase is to be found in Lewin on Trusts, 16th ed. (1964), p. 658, and Underhill's Law Relating to Trusts and Trustees 11th ed (1959) p. 606: it appears first to have been used by Lord Grant M.R. in Parker v. Brooke (1804) 9 Ves. 583, 588. The rule, as I understand it, is that no stranger can become a constructive trustee merely because he is made aware of a disputed claim the validity of which he cannot properly assess. Here it has been rightly conceded that no one can foretell the result of the litigation even if the plaintiffs were to prove all the facts they allege."
"As to facts alleged in a statement of claim, [counsel for the defendants] was, to my mind, correct in submitting that a defendant's solicitor is under no duty to the plaintiffs to inquire into their accuracy for the purposes urged by [counsel for the plaintiff], nor, where there is a likelihood of a conflict of evidence between his client's witnesses and those of the plaintiffs is he under any such duty to assess the result. In coming to this conclusion, I am content to adopt the approach, albeit obiter, of Lush J in La Roche v Armstrong[1922] 1 KB 485 , 491, where he said: "
"Lewison J (as he then was) in Independent Trustee Services Ltd v GP Noble Trustees Ltd[2009] EWHC 161 (Ch) helpfully summarised the proper approach at para. 6 by setting out the four questions which should be addressed: (1) does the claimant have an arguable proprietary claim to the funds in issue? (2) if yes, does the defendant have arguable grounds for denying that claim? (3) if yes, has the defendant demonstrated that without the release of the funds in issue he cannot effectively defend the proceedings (or, it may be added, meet his legitimate living expenses)? (4) if yes, where does the balance of justice lie as between, on the one hand, permitting the defendant to expend funds which might belong to the claimant and, on the other hand, refusing to allow the defendant to expend funds which might belong to it?"
"If there be jurisdiction for a solicitor to have that cleared up pre-emptively then it may well be there can be such cases. But in my view this is not such a case, namely a case in which the court has no idea whether there is any conceivable risk for the solicitors for the defendant. I could have no idea whether there is any danger such that it would be positively wrong to exempt that liability. In those circumstances I come to the conclusion that, sympathetic though I am in the particular facts of this case both to the solicitors and to the defendants (and, knowing, as I do, the solicitors in question, such as to believe that there is no possible risk of situation B in this case), and keen as I am that this action should go ahead in two months' time with legal representation on the part of the defendants, I am satisfied that it is not a case where I can or should say, in advance, that there would be no breach of trust by the expenditure of these moneys, and I content myself with saying, as Rattee J did, that so far as the existence of the injunction is concerned, it can be disregarded. The defendants can act as they would have done if there had been no injunction against expending legal costs on their defence to this action which will come to trial very shortly."
"In a case where the claimant obtains a freezing order in relation to funds held by the defendant, the fact that the order contains the usual proviso allowing the defendant to spend money on legal fees does not mean that the order operates by itself to discharge the defendant's solicitors from potential liability for knowing receipt"
"there is an inherent power under what is now section 37(1) to make any ancillary order, including an order for discovery, to ensure the effectiveness of any other order made by the court."
"Bearing in mind we are exercising a jurisdiction which is statutory, and which is expressed in terms of considerable width, it seems to me that the court should not shrink if it is of the opinion that an injunction is necessary for the proper protection of a party to the action, from granting relief, notwithstanding it may, in its terms, be of a novel character."
"I have no hesitation in saying that there is no limit to the practice of the court with regard to interlocutory applications so far as they are necessary and reasonable applications ancillary to the due performance of its functions, namely, the administration of justice at the hearing of the cause."
