“(6) Common law damages for breach of contract are intended to compensate the claimant for loss or damage resulting from the non-performance of the obligation in question. They are therefore normally based on the difference between the effect of performance and non-performance upon the claimant’s situation. (7) Where damages are sought at common law for breach of contract, it is for the claimant to establish that a loss has been incurred, in the sense that he is in a less favourable situation, either economically or in some other respect, than he would have been in if the contract had been performed. (8) Where the breach of a contractual obligation has caused the claimant to suffer economic loss, that loss should be measured or estimated as accurately and reliably as the nature of the case permits. The law is tolerant of imprecision where the loss is incapable of precise measurement, and there are also a variety of legal principles which can assist the claimant in cases where there is a paucity of evidence. (9) Where the claimant’s interest in the performance of a contract is purely economic, and he cannot establish that any economic loss has resulted from its breach, the normal inference is that he has not suffered any loss. In that event, he cannot be awarded more than nominal damages. (10) Negotiating damages can be awarded for breach of contract where the loss suffered by the claimant is appropriately measured by reference to the economic value of the right which has been breached, considered as an asset. That may be the position where the breach of contract results in the loss of a valuable asset created or protected by the right which was infringed. The rationale is that the claimant has in substance been deprived of a valuable asset, and his loss can therefore be measured by determining the economic value of the right in question, considered as an asset. The defendant has taken something for nothing, for which the claimant was entitled to require payment. (11) Common law damages for breach of contract cannot be awarded merely for the purpose of depriving the defendant of profits made as a result of the breach, other than in exceptional circumstances, following Attorney General v Blake. (12) Common law damages for breach of contract are not a matter of discretion. They are claimed as of right, and they are awarded or refused on the basis of legal principle.”
“It should not be, as he ordered, an assessment of the amount which would notionally have been agreed between the parties, acting reasonably, as the price for releasing the defendants from their obligations. The object of the exercise is that the judge should measure, as accurately as he can on the available evidence, the financial loss which the claimant has actually sustained. How that assessment is best carried out is, in the first instance, a matter for the judge to consider, proceeding in accordance with this judgment. If evidence is led in relation to a hypothetical release fee, it is for the judge to determine its relevance and weight, if any. It is important to understand, however, that such a fee is not itself the measure of the claimant’s loss in a case of the present kind, for the reasons which have been explained.”
“1. A director, while acting as such, has a fiduciary relationship with his Company. That is he has an obligation to deal towards it with loyalty, good faith and avoidance of the conflict of duty and self-interest. 2. A requirement to avoid a conflict of duty and self-interest means that a director is precluded from obtaining for himself, either secretly or without the informed approval of the Company, any property or business advantage either belonging to the Company or for which it has been negotiating, especially where the director or officer is a participant in the negotiations. 3. A director’s power to resign from office is not a fiduciary power. He is entitled to resign even if his resignation might have a disastrous effect on the business or reputation of the Company. 4. A fiduciary relationship does not continue after the determination of the relationship which gives rise to it. After the relationship is determined the director is in general not under the continuing obligations which are the feature of the fiduciary relationship. 5. Acts done by the directors while the contract of employment subsists but which are preparatory to competition after it terminates are not necessarily in themselves a breach of the implied term as to loyalty and fidelity. 6. Directors, no less than employees, acquire a general fund of skill, knowledge and expertise in the course of their work, which is plainly in the public interest that they should be free to exploit it in a new position. After ceasing the relationship by resignation or otherwise a director is in general (and subject of course to any terms of the contract of employment) not prohibited from using his general fund of skill and knowledge, the ‘stock in trade’ of the knowledge he has acquired while a director, even including such things as business contacts and personal connections made as a result of his directorship. 7. A director is however precluded from acting in breach of the requirement at 2 above, even after his resignation where the resignation may fairly be said to have been prompted or influenced by a wish to acquire for himself any maturing business opportunities sought by the Company and where it was his position with the Company rather than a fresh initiative that led him to the opportunity which he later acquired. 8. In considering whether an act of a director breaches the preceding principle the factors to take into account will include the factor of position or office held, the nature of the corporate opportunity, its ripeness, its specificness and the director’s relation to it, the amount of knowledge possessed, the circumstances in which it was obtained and whether it was special or indeed even private, the factor of time in the continuation of the fiduciary duty where the alleged breach occurs after termination of the relationship with the Company and the circumstances under which the breach was terminated, that is whether by retirement or resignation or discharge. 9. The underlying basis of the liability of a director who exploits after his resignation a maturing business opportunity of the Company is that the opportunity is to be treated as if it were the property of the Company in relation to which the director had fiduciary duties. By seeking to exploit the opportunity after resignation he is appropriating to himself that property. He is just as accountable as a trustee who retires without properly accounting for trust property. 10. It follows that a director will not be in breach of the principle set out as point 7 above where either the Company’s hope of obtaining the contract was not a ‘maturing business opportunity’ and it was not pursuing further business orders nor where the director’s resignation was not itself prompted or influenced by a wish to acquire the business for himself. 11. As regards breach of confidence, although while the contract of employment subsists a director or other employee may not use confidential information to the detriment of his employer, after it ceases the director/employee may compete and may use know-how acquired in the course of his employment (as distinct from trade secrets – although the distinction is sometimes difficult to apply in practice).”
"For this purpose the plaintiff must show, first a disposal of his assets in breach of fiduciary duty; secondly, the beneficial receipt by the defendant of assets which are traceable as representing the assets of the plaintiff; and thirdly, knowledge on the part of the defendant that the assets are traceable to a breach of fiduciary duty." [1480] The ingredients of dishonest assistance were set out by Lord Nicholls of Birkenhead in his authoritative opinion in Royal Brunei Airlines Sdn Bhd v. Tan[1995] AC 378 . Although some doubt had existed whether his exposition represented English law, that doubt has been dispelled by the decision of the House of Lords in Twinsectra v. Yardley[2002] 2 AC 164 . In Tan Lord Nicholls summarised the ingredients of liability as follows (p. 392): "
“further, the first and second defendants have dishonestly caused the first claimant to make, unknowingly, other false payments. The claimants rely on the following based on their inquiries to date” and that, following the individual allegations which included certain allegations added by amendment, at [35] it was pleaded that: “in the premises the first and second defendants are liable to pay monies had and received in amounts to be confirmed following full disclosure and the taking of necessary accounts and inquiries”
