Lawton LJ agreed with Lord Denning MR and Lord Diplock. The applicant exercised Option 1 by letter of 2 October 2013. In the end, no delivery date was agreed and the parties did not enter into shipbuilding contracts for the four tankers under the option. Contract law strengthens private enterprise in South Africa and regulates it in the interest of fair trade which, in itself, maintains the principles of Ubuntu. However, when, in an economically efficient society, Ubuntu demands humanity vis-à-vis others, the untouchability of the contract provides a legal framework within which individuals can carry out activities and exchange resources at their discretion, knowing that the law respects and, where appropriate, enforces their agreements. The Commercial Court examined the principles applicable to the agreements to be concluded in the main judicial appel appelle authorities of Mamidoil-Jetoil Greek Petroleum and B J Aviation. One of the fundamental principles that flows from these decisions is that if the parties have agreed on an essential matter in the context of an effective construction of the contract (for example. B the price in a contract for the sale of goods or the provision of services) in the future, the contract is probably unenforceable due to uncertainty. The decisions are also decisive for the argument that, when it is satisfied that the parties intend to implement their agreement, it should endeavour to achieve that intention by the construction or implication of a provision. However, the implied provision must not be contrary to the Tribunal`s conception of explicit contractual conditions. Third, and this is apparent from the second point, it is possible that there is no such necessary implication, given that, given the explicit terms of the agreement, there is clearly no leeway for the importation of the alleged tacit disposition alleged by the respondent. As in Robin v Guarantee Life Assurance Ltd indicates: The facts and issues are briefly as follows: 4.9 The content of the last paragraph of clause 6, relied on by the applicant and Mr Shepherd for the assertions in paragraphs 12, 13, 14 and 16 of the affidavit, was never discussed or mentioned during the negotiations. It was never agreed and was not part of the common intention.
On the other hand, Mr. Shepherd, who was responsible for drawing up the lease, appears to have used the usual form of contact with the assignor, but did not draw my attention to the last paragraph of Article 6. I did not notice or expect this provision in the context of the lease agreement, given clauses 6, 10, 15 and 16 of the terms and conditions and clause 6, with the exception of the last paragraph („last paragraph“). Nor did I have any reason to believe that this would be the reason to think that it would run counter to our common intention. Finally, Article 15 of the conditions expressly provides for an extension period of 5 + 5 years and clause 10 of the conditions sets the escalation rate at 8%. The existence of the last paragraph under clause 6 is the result of a bona foil error or intentional act by Mr. Shepherd and does not reflect the common intent. This provision is contrary to the conditions and to the common intention. It was never foreseen or agreed that we should renegotiate an extension or its terms, as Mr. Shepherd; „4.2 The parties to the lease have voluntarily agreed to arbitration proceedings without the right of recourse with respect to disputes arising out of the actual intent and importance of the lease or its performance;“ This preliminary opinion of Lord Wright does not seem to me to be well founded.
If the law does not recognize a contract for the conclusion of a contract (if there is still a fundamental period to be agreed), it seems to me that it cannot recognize a contract to be negotiated.  (iii) „Finally, in many cases, the promise to negotiate in good faith will be made within the framework of an `agreement` (to use a neutral term) which, by reason of its nature, purpose, context, other provisions or otherwise, will make it clear that the undertaking is too illusory, too vague and uncertain to be applicable.“ . . .
