The LPI was not set out in the Plaintiff’s Statement of Account issued in May 2022 [16] While waiver is an equitable defence and requires no consideration (see Associated Pan Malaysia Cement Sdn Bhd v Syarikat Teknikal & Kejuruteraan Sdn Bhd [1990] 3 MLJ 287 and section 64 Contracts Act 1950), mere acts of indulgence will not amount to waiver. A waiver requires proof of a clear and unequivocal representation, sufficient reliance on that representation and alteration of position. Per Halsbury’s Laws of Malaysia – Equity [290.401]: “Where the waiver is not express, it may be implied from conduct which is inconsistent with the continuance of the right, apparently without the need for writing or for consideration moving from, or detriment to, the party who benefits by the waiver, but mere acts of indulgence will not amount to waiver; nor may a party benefit from the waiver unless he has altered his position in reliance on it. The waiver may be terminated by reasonable, but not necessarily formal, notice or when the relevant period of suspension of rights expires, unless the party who benefits by the waiver cannot resume his position or termination would cause injustice to him.” [17] As a matter of both pleading and evidence, the Defendant did not tender payment at any time before the Plaintiff initiated legal action to enforce the right to recover the LPI. The Plaintiff had reserved the right to claim interest in the letter of demand. There was still no tender of payment by the Defendant or alteration of its position in reliance on the Plaintiff’s Statement of Account. [18] For this reason, I agree that this case warrants appellate interference. To the extent that the trial Judge found that the case turned on waiver and estoppel, this is an appealable error. Penalty Interest [19] There was a second finding by the Sessions Court Judge that may or may not have underpinned the decision to dismiss the Plaintiff’s claim for LPI, that is, as to the excessiveness of the LPI. On this, parties did not offer any submissions, but to address it briefly, the law on section 75 of the Contracts Act 1950 was settled in Cubic Electronics Sdn Bhd (in liquidation) v Mars Telecommunications Sdn Bhd [2019] CLJ 723 and that is the party alleging unreasonableness must prove it. [20] Thus, the onus was on the Defendant to produce industry or other evidence to demonstrate that 3% per month LPI is unreasonable, but no such evidence was adduced. There is no law that says contractual interest exceeding the rate provided for in the Moneylenders Act 1951 is ipso facto unenforceable. Judgments for contractual interest at 3% per month were also not unprecedented in the law reports. [21] For completeness, the Sessions Court also concluded that the LPI claim was an afterthought because SP1 who testified for the Plaintiff left the calculation of it to the Plaintiff’s solicitors. This Court did not see this as a substantive issue. The computation of interest was straightforward as the parameters of the calculations were clearly shown in the pleading as follows: Conclusions [22] For the reasons set out above, this Court overturned the Judgment of the Sessions Court and allowed the Appellant/Plaintiff’s claim for LPI on the Invoices with costs of RM10,000.00.
