"The obligation not to profit from a position of trust, or, as it is sometimes relevant to put it, not to allow a conflict to arise between duty and interest, is one of strictness. The strength, and indeed the severity, of the rule has recently been emphasised by the House of Lords: Phipps v. Boardman [1967] 2 A.C. 46. It retains its vigour in all jurisdictions where the principles of equity are applied. Naturally it has different applications in different contexts. It applies, in principle, whether the case is one of a trust, express or implied, of partnership, of directorship of a limited company, of principal and agent, or master and servant, but the precise scope of it must be moulded according to the nature of the relationship. As Lord Upjohn said in Phipps v. Boardman, at p. 123: 'Rules of equity have to be applied to such a great diversity of circumstances that they can be stated only in the most general terms and applied with particular attention to the exact circumstances of each case.'"
“Put shortly there was no mutuality giving rise to the undertaking or imposition of a duty of loyalty.”
“(1) No period of limitation prescribed by this Act shall apply to an action by a beneficiary under a trust, being an action— (a) in respect of any fraud or fraudulent breach of trust to which the trustee was a party or privy; or (b) to recover from the trustee trust property or the proceeds of trust property in the possession of the trustee, or previously received by the trustee and converted to his use. (3) Subject to the preceding provisions of this section, an action by a beneficiary to recover trust property or in respect of any breach of trust, not being an action for which a period of limitation is prescribed by any other provision of this Act, shall not be brought after the expiration of six years from the date on which the right of action accrued.”
“(1) The following time limits under this Act, that is to say— (a) the time limit under section 2 for actions founded on tort; (b) the time limit under section 5 for actions founded on simple contract; … shall not apply to any claim for specific performance of a contract or for an injunction or for other equitable relief, except in so far as any such time limit may be applied by the court by analogy in like manner as the corresponding time limit under any enactment repealed by theLimitation Act 1939 was applied before1st July 1940 .”
“(1) … where in the case of any action for which a period of limitation is prescribed by this Act, either— (a) the action is based upon the fraud of the defendant; or (b) any fact relevant to the plaintiff's right of action has been deliberately concealed from him by the defendant; or (c) the action is for relief from the consequences of a mistake; the period of limitation shall not begin to run until the plaintiff has discovered the fraud, concealment or mistake (as the case may be) or could with reasonable diligence have discovered it. References in this subsection to the defendant include references to the defendant's agent and to any person through whom the defendant claims and his agent. (2) For the purposes of subsection (1) above, deliberate commission of a breach of duty in circumstances in which it is unlikely to be discovered for some time amounts to deliberate concealment of the facts involved in that breach of duty.”
“The first covers those cases already mentioned, where the defendant, though not expressly appointed as trustee, has assumed the duties of a trustee by a lawful transaction which was independent of and preceded the breach of trust and is not impeached by the plaintiff. The second covers those cases where the trust obligation arises as a direct consequence of the unlawful transaction which is impeached by the plaintiff.”
“[89] A similar distinction to that drawn in the law of trusts is drawn in cases of breach of fiduciary duty. The fiduciary relationship has developed by analogy from the trust relationship to cover cases in which a person has assumed responsibilities for the management of another person's assets. There is a distinction between— 'those whose fiduciary obligations preceded the acts complained of and those whose liability in equity was occasioned by the acts of which complaint was made.' (See[1999] 1 All ER 400 at 414.) [90] For limitation purposes the two classes of trust and/or fiduciary duty are treated differently. The first class of case arising from the breach of a pre-existing duty is, or is treated by analogy as, an action by a beneficiary for breach of trust falling within s 21(1) of the 1980 Act. This means that there is no limitation period for the cases falling within s 21(1)(a) or (b); but that there is a six-year limitation period for cases falling within s 21(3). [91] In the second class of case s 21 would not apply, but a limitation defence to a claim might be available by analogy with common law claims, such as tort (for example, deceit) or breach of contract, even though the liability is exclusively equitable, as may be the case with breaches of fiduciary duty in the absence of a contract.”
“The question is not whether the plaintiffs should have discovered the fraud sooner; but whether they could with reasonable diligence have done so. The burden of proof is on them. They must establish that they could not have discovered the fraud without exceptional measures which they could not reasonably have been expected to take. In this context the length of the applicable period of limitation is irrelevant. In the course of argument May LJ observed that reasonable diligence must be measured against some standard, but that the six-year limitation period did not provide the relevant standard. He suggested that the test was how a person carrying on a business of the relevant kind would act if he had adequate but not unlimited staff and resources and were motivated by a reasonable but not excessive sense of urgency. I respectfully agree.”
