96 See Peel, „The Status of Agreements“, p. 40 (challenging Lord Ackner`s distinction in Walford between an enforceable duty to apply „best efforts“ and an unenforceable obligation to negotiate in good faith, and proposes that neither be enforceable). 127 Cf. z.B. Peel, „The Status of Agreements“, pp. 43-47. On the implied obligation of a lessor to negotiate an extension of a lease in good faith, see Empress Towers Ltd. v. Bank of Nova Scotia  73 D.L.R.

See also Yam Seng  EWHC 111, in abs. , where Leggatt J. the relevance of a „faithful“ action in relation to the promise related to good faith in the execution of an agreement. Cable & Wireless plc v IBM United Kingdom Ltd (2002) EWHC 2059) reflects the same propensity to impose, to the extent possible, an explicit duty to apply good faith. The contract in question contained a clause obliging the parties to attempt „in good faith“ to settle disputes between themselves „through an alternative dispute resolution procedure (ADR), as recommended to the parties by the Dispute Resolution Centre“.
The General Court rejected the argument put forward that this is only an obligation to apply good faith in negotiations and that it is not applicable as such. On the contrary, the obligation is safe enough to be enforceable, as it has set out the means of trying in good faith. If a party refused to participate in the prescribed proceedings, it would have failed in its duty. The judge indicated that if the clause had simply compelled the parties to attempt, in good faith, to settle their disputes, this obligation would have been void for reasons of uncertainty. With regard to the regulation of international commercial contracts, the main text is the UNIDROIT Principles of International Commercial Contracts (PICC) of 2016, as several articles of the PICC may be relevant in case of preliminary agreements, for example.B.: Article 2.1.1 (type of creation), art. 2.1.2-2.1.12 (art. on offer and acceptance), article 2.1.13 (conclusion of the contract on the basis of agreement on certain matters or in a given form), art. 2.1.14 (contract with conditions deliberately left in abeyance), Article 2.1.16 (obligation of confidentiality).
This presentation/work focuses on art. 2.1.15 (negotiations in bad faith) because it explicitly refers to the possibility for the international parties to conclude a pre-agreement and to explicitly undertake to negotiate in good faith the conclusion of the final contract. A similar approach was taken under a 15-year coal supply contract. The contract contained detailed provisions for the calculation of the price to be paid during the first five years, but included that the price was then agreed by the parties.. . . .
