MAIN OBJECTIVES The Developer and NCP shall use all reasonable endeavours to achieve the Main Objectives and shall act in good faith in respect of the same and in accordance with this Agreement. The term "Main Objectives" is defined in clause 1. The Main Objectives were: (a) to carry out the CT Project in a manner commensurate with a prudent commercial developer; (b) so far as reasonably practicable to minimise the period required in order to obtain the CT Required Permissions; and (c) to use reasonable endeavours to incorporate proposals for a commercially viable public car park within the CT Project for which planning permission could be obtained free from unduly onerous conditions. It was not in dispute that that referred to proposals for a car park within the Castle Terrace site. As I have already noted, the "CT Project", which is also defined in Clause 1, comprised the whole development of the site, including the design and construction of the works and the letting of the lettable units on the market. The term "CT Required Permissions" encompassed "every permission, consent, permit, licence, approval and agreement" which was required, whether by statute, contract or otherwise, for the complete implementation of the CT Project. … [19] There was some discussion before me as to the nature of an obligation to use “all reasonable endeavours”. Relying upon the decision of Deputy Judge Flaux Q.C. in Rhodia International Holdings Limited v Huntsman International LLC [2007] 2 Lloyds Rep. 325 at paras. 30-35, Mr Clark Q.C., for NCP, submitted that an obligation to use “all reasonable endeavours” was a more stringent obligation, or imported a higher test, than an obligation simply to use “reasonable endeavours”. That submission was supported by McBryde, The Law of Contract in Scotland, 3rd Ed. at para.8-57. Under reference to Sheffield District Railway Company v Great Central Railway Company (1911) 27 TLR 451, he submitted that, broadly speaking, it meant that the person on whom the obligation was placed must “leave no stone unturned”. Mr McLean Q.C., for EDI, did not, I think, dissent from the proposition that the word “all” in “all reasonable endeavours” was sufficient to raise the bar. But he emphasised, under reference to the same paragraph in McBryde, that a party is not required under such a provision to act beyond his own commercial interests. That submission finds some support in Rhodia at para. 35, citing the judgment of Lewison J in Yewbelle Limited v London Green Developments Limited [2006] EWHC 3166 (Ch), with the caveat, which is not in point here, that in some cases the contract may specify steps which have to be taken regardless of the commercial interest of the party required to take them. In Stephen v Scottish Boat Owners Mutual Insurance Association 1989 S.C. (H.L.) 24 at 61, a case concerned with whether the skipper of a fishing boat had used all reasonable endeavours to save his vessel, Lord Keith of Kinkel, at p.61, said that the test was an objective one directed to ascertaining "what an ordinarily competent fishing boat skipper might reasonably be expected to do in the same circumstances." Mr McLean submitted that this test should be applied mutatis mutandis in the present case. Equating “all reasonable endeavours” with “best endeavours”, which was the analysis adopted in Rhodia, Mr McLean referred me to a number of other statements from other cases. In IBM United Kingdom Limited v Rockware Glass Limited [1980] FSR 335, the Court of Appeal held that a person under an obligation to use best endeavours was obliged to take steps “which a prudent, determined and reasonable owner, acting in his own interests and designed to achieve that result would take”. He also referred to the decision of the Court of Appeal in Yewbelle [2007] EWCA Civ. 475. Though the appeal from Lewison J was allowed, his decision on the meaning of all reasonable endeavours was expressly approved on this point in the Court of Appeal: see per Lloyd LJ at paras.29-33. Further, at paras.103 and 127, the Court of Appeal emphasised, in agreement with the judge, that the obligation to use all reasonable endeavours does not require a party to go on trying when it is clear that in one respect at least he must fail. Thus, if there were two or three obstacles to be overcome, and it became clear that one of those obstacles was in fact insuperable, there would be no obligation on the party to continue using all reasonable endeavours to overcome the other two. That would be a fruitless exercise. [20] There was little between the parties on this point. I accept the submission that the obligation to use “all reasonable endeavours” is a more onerous obligation than one simply to use “reasonable endeavours”. I do not have to consider whether or not it is the same as one to use “best endeavours”, though I would have thought that any difference is likely to be metaphysical rather than practical. It is difficult to conceive that an obligation to use “best endeavours” requires a party to take steps which are ex hypothesi unreasonable. I base my conclusion that an obligation to use “all reasonable endeavours” is more onerous than one merely to use “reasonable endeavours” on the analysis adopted in Rhodia, under reference to other authorities; but I am fortified in that conclusion by the recent opinion of Lord Hodge in MacTaggart & Mickel Homes Limited v Hunter & Hunter [2010] CSOH 130 at para. [63]. It is not, I think, helpful to attempt to define more precisely what is encompassed by that obligation. It will, as Lord Hodge suggests, require the Court to consider whether there were reasonable steps which could have been taken but were not taken. The party on whom the obligation is placed will be expected to explore all avenues reasonably open to him, and to explore them all to the extent reasonable. But unless the contract otherwise stipulates, he is not required to act against his own commercial interests: see Yewbelle, and see also the recent decision of Vos J in CPC Group v Qatari Diar Real Estate Investment Co. [2010] EWHC 1535 (Ch) at para.252, a decision which came to my attention after the conclusion of the proof. That point is, in any event, made clear here by the reference in clause 6 to the standards of “a normal prudent commercial developer experienced in developments of that nature”. The word “prudent” points to a legitimate consideration of his own financial and commercial interests. Nor is he required to persist where it is clear that further efforts will be fruitless. The reference to the developer being “experienced in developments of that nature”, shows that he is entitled to rely upon his judgement, informed by his experience, of what is and is not likely to bear fruit. If it is clear that he cannot succeed whatever further avenues he may take, he cannot be expected to continue wasting time, effort and expense. So also, if it becomes clear that one necessary hurdle cannot be overcome, he will not be expected to waste his time seeking to overcome other problems, since overcoming them would achieve nothing. [21] I would add only two points. The first is a point of detail which emerges from para. 105 of the judgment of the Court of Appeal in Yewbelle. Lloyd LJ there emphasises that it may well be part of the obligation to use all reasonable endeavours for the party on whom the obligation is placed to inform the other party of any difficulties he is encountering and, in an appropriate case, to see whether that party has a possible solution to the problem. That must be right. A party cannot just sit back and say that he could not reasonably have done more when, if it had had asked the other party to the transaction, it might have discovered that there were other steps which could reasonably have been taken. But all will depend upon the circumstances. [22] The other point concerns the onus of proof. As I said earlier, NCP led at proof. This was because they accepted that the burden was on them to show that EDI were in breach, so as to give a basis for the mutuality argument. But it does not seem to me that the burden necessarily remains throughout on NCP. My tentative view is that if NCP can point to steps which could have been taken, by evidence (or possibly by pleading), the evidential burden may shift to EDI to show, as the case may be, that they took those steps, that they could not reasonably have been expected to take them or that such steps would have been bound to fail. It is EDI who are likely to have the evidence on these points and, once a sufficient case has been raised by NCP, the burden must ultimately be on EDI to establish that they used all reasonable endeavours as required by the Agreement: c.f. MacTaggart & Mickel Homes Limited at para. 58 in which Lord Hodge refers to the onus of proof being on the party asserting that he has used reasonable endeavours. However, the point was not argued before me and, in the conclusions I have reached, it makes no difference to the outcome.” (Emphasis added) [122] In our perusal of the central feature of the reasoning on the subject, we find that the original context of Lord Glennie’s remark in paragraphs [19] to [21] of EDI Central Ltd, cited above, pertained to the obligation to use “all reasonable endeavours” as evident from the language of the contract reproduced in paragraph [10] of the same judgment. Lord Glennie’s observation of the law was cited with approval by V.K. Rajah JA in KS Energy Services Ltd, also in the context of the “all reasonable endeavours” clause and the “best endeavours” clause. [123] In both cases, there was a consensus that an obligation to exercise “reasonable endeavours” is less onerous than an obligation to exercise “all reasonable endeavours” and that of “best endeavours.” It was also made plain in KS Energy Services Ltd that an obligor under a “reasonable endeavours” obligation is not subject to the Travista test. KS Energy Services Ltd was later cited with approval by our Court of Appeal in Kumpulan Prasarana Rakyat Johor Sdn. Bhd. v. Emercon Bina Sdn. Bhd. and another appeal [2021] 1 MLJ 629 (CA), also in the context of a “best endeavours” obligation. [124] With respect, by attempting to fit the guidance in these cases to the facts of the present appeal, learned counsel for the Defendant was trying to force a square peg into a round hole. To our mind, the “steps” referred to in those cases do not apply to the facts of the present appeal. In the appeal before us, the Defendant relied on the email correspondence dated 25.5.2015 and 22.6.2015 several years after the 2013 Agreement was entered into by the parties. In our considered view, the Defendant cannot rely on these emails to amplify or modify the 2013 Agreement. [125] In our judgment, the law is clear. We agree with the Plaintiff that the burden of proof in reliance on a reasonable endeavours clause falls first on the obligee, i.e., the Defendant. [126] It follows that, unlike in the case of a guaranteed undertaking where it is sufficient for the obligee to prove that the aim for the contractually guaranteed result has not been procured, in the case of an obligation of reasonable endeavour, proof of the promised result is not achieved is not sufficient since the mere fact that the result has not been achieved does not necessarily mean that the obligor has not properly performed its obligation. It is incumbent upon the obligee to prove that the obligor has not discharged its obligation with the reasonable diligence required. [127] The learned panel of the Court of Appeal at paragraph [37] had this to say: “[37] For completeness, we find that the Respondent has also not led sufficient evidence to satisfy us that the Appellant did not use its reasonable endeavour required under clause 4.3 of the 2013 Agreement to find any liability on the part of the Appellant in justification of its set off and counterclaim on this aspect.” [128] We agree with the view expressed by the learned panel of the Court of Appeal. The Court of Appeal unanimously held that the Defendant has not led sufficient evidence that the Plaintiff did not use their reasonable endeavour required under Clause 4.3. We, therefore, shall refrain from further analysis of the evidence and findings thereon. [129] We hold that the burden of proof does not shift to the Plaintiff as contended by the Defendant. The burden of proof lies with the Defendant as the obligee is consistent with the classic juridical aphorism “semper necessitas probandi incumbit ei qui agit” (he who asserts must prove) which is statutorily recognised by section 101 of our Evidence Act 1950 [Act 50]. There is no extrinsic evidence led by the Defendant to support their contention that the Plaintiff had failed to exercise reasonable endeavour as stipulated under Clause 4.3 of the 2013 Agreement. The Defendant has failed to discharge their burden of proof. [130] For these reasons, we answer Question 5 in the NEGATIVE.
