To ensure I have provided clarity on why I find that the said issue of waiver / estoppel was sufficiently pleaded by the Defendant, I refer to the decision of the Court of Appeal in Double Advantage Sdn Bhd v Paduan Hebat Sdn Bhd & Anor [2017] CLJU 1391 as follows: - [34] Useful reference on the law relating to estoppel may be had to the Federal Court decision of Boustead Trading (1985) Sdn Bhd v. Arab-Malaysian Merchant Bank Bhd [1995] 4 CLJ 283; [1995] 3 MLJ 331 where in S/N We1yXbjtHkuB9deAqr93A speaking for the Court, Gopal Sri Ram JCA (as he then was) observed (at p 344-345): "The time has come for this court to recognize that the doctrine of estoppel is a flexible principle by which justice is done according to the circumstances of the case. It is a doctrine of wide utility and has been resorted to in varying fact patterns to achieve justice. Indeed, the circumstances in which the doctrine may operate are endless." [35] Considering the circumstances as set out earlier, we think that at least estoppel by acquiescence or estoppel by silence or inaction applies to the instant case. The test as to estoppel by acquiescence can be found in Moorgate Mercantile Co Ltd v. Twitchings [1976] 2 All ER 641 through the dissenting speech of Lord Wilberforce as follows (at p 645-646): "In order that silence or inaction may acquire a positive content it is usually said that there must be a duty to speak or to act in a particular way, owed to the person prejudiced... What I think we are looking for here is an answer to the question whether, having regard to the situation in which the relevant transaction occurred, as known to both parties, a reasonable man, in the position of the "acquirer" of the property, would expect the "owner" acting S/N We1yXbjtHkuB9deAqr93A honestly and responsibly, if he claimed any title in the property, to take steps to make the claim known..." (as cited with approval in Republic of India & another v. India Steamship Co Ltd (The Indian Endurance) (No. 2) [1996] 3 All ER 641). [36] In the case of The Stolt Loyalty [1993] 2 Lloyd's Rep 281, Clarke J (as he then was) had occasion to consider the authorities dealing with estoppel by acquiescence or estoppel by silence or inaction as follows (at pp 289- 290): "The question is whether on those facts the demise charterers are estopped from relying upon the one year time limit. I was referred to a number of cases in which estoppel by acquiescence or estoppel by silence or inaction has been discussed. An estoppel of this type is an equitable estoppel. In recent years there has been a tendency to reject "any rigid classification of equitable estoppel into exclusive and defined categories"; per Mr. Justice Robert Goff in Amalgamated Investment & Property Co. Ltd, v. Texas Commerce International Bank Ltd., [1982] 1 Q.B. 84 at pp. 103 to 104. Nevertheless, the following cases appear to me to establish that before a person can be held to be estopped as a result of mere inaction he must be S/N We1yXbjtHkuB9deAqr93A shown to be under a legal duty to take action of some kind: Spiro v. Lintern, [1973] 1 W.L.R. 1002; The Henrik Sif, [1982] 1 Lloyd's Rep. 456. The question then arises in what circumstances a person may be held to be under such a legal duty. In The Henrik Sif Mr. Justice Webster, after citing a dictum of Lord Wilberforce in Moorgate Mercantile Co. Ltd. v. Twitchings, [1977] A.C. 890 at p. 903, answered that question in this way (at p. 465): Nonetheless the dictum which I have cited seems to me to be most persuasive authority for the proposition that the duty necessary to found an estoppel by silence or acquiescence arises where "a reasonable man would expect' the person against whom the estoppel is raised "acting honestly and responsibly" to bring the true facts to the attention of the other party known by him to be under a mistake as to their respective rights and obligations. Mr. Justice Webster also cited with approval the following passage from the judgment of Mr. Justice Oliver in Taylor Fashions Ltd. v. Liverpool Victoria Trustee Co. Ltd., [1982] 1 Q.B. 133 at p. 147: ... in a case of mere passivity, it is readily intelligible that there must be shown a duty to speak, protest or interfere S/N We1yXbjtHkuB9deAqr93A which cannot normally arise in the absence of knowledge or at least a suspicion of the true position. The underlying basis for the existence of this estoppel, as in the case of all equitable estoppel, is that it must be unconscionable to allow the party estopped to deny that which he has allowed the other party to assume to be true. In the case just cited Mr. Justice Oliver put it thus (at pp. 151 to 152): Furthermore the more recent cases indicate, in my judgment, that the application of the Ramsden v. Dyson, L.R. 1 H.L. 129 principle - whether you call it proprietary estoppel, estoppel by acquiescence or estoppel by encouragement is really immaterial - requires a very much broader approach which is directed rather at ascertaining whether, in particular individual circumstances, it would be unconscionable for a party to be permitted to deny that which, knowingly, or unknowingly, he has allowed or encouraged another to assume to his detriment than to enquiring whether the circumstances can be fitted within the confines of some preconceived formula serving as a universal yardstick for every form of unconscionable behavior. That statement of principle was expressly approved by the Court of Appeal in Habib Bank Ltd. v. Habib Bank A.G. Zurich, [1981] 1 W.L.R. 1265. S/N We1yXbjtHkuB9deAqr93A There is a further aspect of this type of estoppel which is of importance. It was put in this way by Lord Justice Kerr giving the judgment of the Court of Appeal in The August Leonhardt, [1985] 1 Lloyd's Rep. 28 at p. 35: The applicability of the doctrine of estoppel in any given case can also be tested in another way. There cannot be any estoppel unless the alleged representor has said or done something, or failed to do something, with the result that - across the line between the parties - his action or inaction has produced some belief or expectation in the mind of the alleged representee, so that, depending on the circumstances, it would thereafter no longer be right to allow the alleged representor to resile by challenging the belief or expectation which he has engendered. To that extant at least, therefore the alleged representor must be open to criticism."
