⁵⁶ “Good faith” on its own is different from the composite expression “good faith and fair dealing”, which introduces an objective standard of conduct. The Draft Common Frame of Reference keeps the concepts separate: “good faith” is defined as “a mental attitude characterised by honesty and an absence of knowledge that an apparent situation is not the true situation” (see list of definitions introduced by Art. I-1:108); “good faith and fair dealing” is “a standard of conduct characterised by honesty, openness and consideration for the interests of the other party to the transaction or relationship in question” (Art. I-1:103); and “reasonableness” is “to be objectively ascertained, having regard to the nature and purpose of what is being done, to the circumstances of the case and to any relevant usages and practice” (Art. I-1:104): Von Bar, C. & Clive, E. (eds.), Principles, Definitions and Model Rules of European Private Law, Draft Common Frame of Reference (DFCR) (Oxford 2010)Google Scholar.

⁵⁹ Ibid.. Because Stapleton (at 11–12) distinguishes “good faith” from “fair” or “reasonable” dealing (“an objective norm of behaviour”) she is critical of Bingham L.J.'s dictum in Interfoto Picture Library Ltd. v Stiletto Visual Programmes Ltd., note 44 above, 439, that “good faith...is in essence a principle of fair and open dealing” (a “regrettable development”).

Socimer [2008] EWCA Civ 116 and Looney v Trafigura Beheer BV [2011] EWHC 125 (Ch) are cited in support of that statement. However, it is submitted that in both cases the court focused on, and rejected, the imposition of an objective standard of reasonableness, and was not concerned with the different question of whether a control on contractual discretion based on a subjective standard of honesty and good faith could be excluded by the terms of the contract.

¹¹² Although, as stated below (see notes 115 and 116), the injured party may sometimes have no choice but to terminate.

¹¹³ Doctrinal incoherence arises where, on closer analysis, there is no rationale for treating certain transactional elements in different ways. For example, it is submitted that it is incoherent to limit the “practical benefit” test to promises to pay more (as in Williams v Roffey Bros & Nicholls (Contractors) Ltd. [1991] 1 Q.B. 1, C.A.), so that promises to pay less are subject to different doctrinal rules (as confirmed in Re Selectmove Ltd. [1995] 1 W.L.R. 474, C.A.).

Brownsword proposes (at pp. 92 and 237 respectively) that “a right to withdraw would be available where it was conferred by legislation or case law, or where it was so agreed by the parties; but, failing such special provision, the right to withdraw would depend upon the innocent party having good reason for claiming the option of release from the contract, as opposed to settling for damages” – the proposal is criticised by E.

¹⁴¹ Quaere whether a standard of subjective honesty also applies where a party elects to rescind a contract on grounds of misrepresentation, duress or undue influence. It is arguable that, for reasons of consistency, the same standard should apply in these cases, although that argument is not explored in this paper, which is restricted to cases of termination for breach. However, unlike termination for breach, which operates de futuro, rescission sweeps away a voidable contract ab initio and leaves no scope for implying a term (or construing an express term) similar to that implied in cases of contractual discretion (although certain clauses, such as an exclusive jurisdiction clause or an arbitration clause, may survive rescission: see D. O'Sullivan, S. Elliott and R. Zakrzewski, The Law of Rescission (Oxford 2008), para. 1.12). This explains, for example, why a court must rely on the wide statutory discretion contained within s. 2(2) of the Misrepresentation Act 1967 to refuse rescission and award damages instead following a non-fraudulent misrepresentation (see J. Cartwright, Misrepresentation, Mistake and Non-Disclosure, 3^rd ed. (London 2012), paras. 4-61 et seq).
