Lord Haldane, L. C., in Nocton v. Lord Ashburton (1914) Appeal Cases, 932, 945–946, 951–954

I have read the evidence of the appellant, and, although it is obviously unreliable evidence, it leaves on my mind the same impression that it left on that of the learned judge who heard it, that the solicitor did not consciously intend to defraud his client, but, largely owing to a confused state of mind, believed that he was properly joining with him and guiding him in a good speculation.

I cannot, therefore, treat the case, so far as based on intention to deceive, as made out. But where I differ from the learned judges in the Courts below is as to their view that, if they did not regard deceit as proved, the only alternative was to treat the action as one of mere negligence at law unconnected with misconduct. This alternative they thought was precluded by the way the case had been conducted. I am not sure that, on the pleadings and on the facts proved, they were right even in this. The question might well have been treated as in their discretion and as properly one of costs only, having regard to the unsatisfactory evidence of the appellant. But I do not take the view that they were shut up within the dilemma they supposed. There is a third form of procedure to which the statement of claim approximated very closely, and that is the old bill in Chancery to enforce compensation for breach of a fiduciary obligation. There appears to have been an impression that the necessity which recent authorities have established of proving moral fraud in order to succeed in an action of deceit has narrowed the scope of this remedy. For the reasons which I am about to offer to your Lordships, I do not think that this is so....

My Lords, it is known that in cases of actual fraud the Courts of Chancery and of Common Law exercised a concurrent jurisdiction from the earliest times. For some of these cases the greater freedom which, in early days, the Court of Chancery exercised in admitting the testimony of parties to the proceedings made it a more suitable tribunal. Moreover, its remedies were more elastic. Operating in personam as a Court of conscience it could order the defendant, not, indeed, in those days, to pay damages as such, but to make restitution, or to compensate the plaintiff by putting him in as good a position pecuniarily as that in which he was before the injury.

But in addition to this concurrent jurisdiction, the Court of Chancery exercised an exclusive jurisdiction in cases which, although classified in that Court as cases of fraud, yet did not necessarily import the element of dolus malus. The Court took upon itself to prevent a man from acting against the dictates of conscience as defined by the Court, and to grant injunctions in anticipation of injury, as well as relief where injury had been done. Common instances of this exclusive jurisdiction are cases arising out of breach of duty by persons standing in a fiduciary relation, such as the solicitor to the client, illustrated by Lord Hardwicke’s judgment in Chesterfield v. Janssen, 2 Ves. Sen. 125. I can hardly imagine that those who took part in the decision of Derry v. Peek, 14 App. Cas. 337, imagined that they could be supposed to have cast doubt on the principle of any cases arising under the exclusive jurisdiction of the Court of Chancery. No such case was before the House, which was dealing only with a case of actual fraud as to which the jurisdiction in equity was concurrent....

So far as the equity jurisdiction in cases of what is called fraud is concurrent only and exercised in actions for mere deceit apart from breach of special duty, an actual intention to cheat has now to be proved. But there are cases of other classes to which, as I have already said, the Court of Chancery undoubtedly did apply the term fraud, although I think unfortunately.

Fraud in such cases is, as James, L. J., said in Torrance v. Bolton, L. R. 8 Ch. 118, at p. 124, “nomen generalissimum, and it must not be construed so as to mislead persons into the notion that contracts for the sale and purchase of lands are in any respect privileged, so as to be free from the ordinary jurisdiction of the Court to deal with them as it deals with any instrument, or any other transactions, in which the Court is of opinion that it is unconscientious for a person to avail himself of the legal advantage which he has obtained. Indeed, the books are full of cases in which the Court has dealt with contracts of that kind—contracts obtained by persons from others over whom they have dominion, contracts obtained by persons in a fiduciary position, contracts for the sale of shares obtained by directors through misrepresentation contained in the prospectus, in respect of which it was never necessary to allege or prove that the directors were wilfully guilty of moral fraud in what they had done.” In Chancery the term “fraud” thus came to be used to describe what fell short of deceit, but imported breach of a duty to which equity had attached its sanction. What was laid down by Lord Eldon in this House in Bulkely v. Wilford, 2 Cl. & F. 102, at p. 177, explains the nature of the duty.

My Lords, I have dealt thus fully with this distinction because I think that confusion has arisen from overlooking it. It must now be taken to be settled that nothing short of proof of a fraudulent intention in the strict sense will suffice for an action of deceit. This is so whether a Court of Law or a court of equity in the exercise of concurrent jurisdiction is dealing with the claim, and in this strict sense it was quite natural that Lord Bramwell and Lord Herschell should say that there was no such thing as legal as distinguished from moral fraud. But when fraud is referred to in the wider sense in which the books are full of the expression, used in Chancery in describing cases which were within its exclusive jurisdiction, it is a mistake to suppose that an actual intention to cheat must always be proved. A man may misconceive the extent of the obligation which a Court of Equity imposes on him. His fault is that he has violated, however innocently because of his ignorance, an obligation which he must be taken by the Court to have known, and his conduct has in that sense always been called fraudulent, even in such a case as a technical fraud on a power. It was thus that the expression “constructive fraud” came into existence. The trustee who purchases the trust estate, the solicitor who makes a bargain with his client that cannot stand, have all for several centuries run the risk of the word fraudulent being applied to them. What it really means in this connection is, not moral fraud in the ordinary sense, but breach of the sort of obligation which is enforced by a Court that from the beginning regarded itself as a Court of conscience.
