06.04.2020 and 01.06.2020, though the Defendant had complained, alleging that the products delivered was not according to specification, inaccurate and incorrect. It is apparent that the Defendant did not dispute the invoices and had made part payments. This to my mind is a clear admission of indebtedness. In the case of Boustead Trading (1985) Sdn Bhd v. Arab-Malaysian Merchant Bank Bhd [1995] 4 CLJ 283; [1995] 3 MLJ 331 where the Federal Court held that: - "(1) A reasonable man in the respondent's position would be entitled to assume that the appellant had agreed to the imposition of the 14-day period as it did not merely remain silent by not objecting to it but had in fact made payment on some invoices. The appellant should not be allowed to question the validity of the indorsement after seven months as it would be unconscionable and inequitable for it to do””. [17] The Defendant in the present case, by making partial payments, has similarly acknowledged his liability. Accordingly, it is my considered view that the Defendant’s repeated admissions and partial payments substantiate the Plaintiff’s claim that he remains liable for the outstanding sums. [18] The Defendant, in his defence, raised several arguments to contest his liability, the most prominent being late delivery by the Plaintiff. The Defendant claimed that the Products were not delivered within the six-month period stipulated in the purchase orders. [19] The Plaintiff contends, and I accept, that the contracts did not specify a fixed delivery period and that delivery was contingent upon obtaining the necessary government permits. This condition was explicitly acknowledged by the Defendant. [20] Even if the six-month delivery period had been validly incorporated into the contracts, the Defendant expressly waived this stipulation in his letter dated 21.6.2018, where he confirmed that he could not take delivery at the designated time and requested that the Plaintiff store the Products for a later delivery date. The Defendant further accepted the transfer of risks for accidental loss or damage and reaffirmed his obligation to pay the full purchase price. [21] Reference was made to the case of Sharikat Eastern Plastics Industry v Sharikat Lam Seng Trading [1972] 1 MLJ 21, where the High Court held that a party who indulges in further negotiations after a stipulated time for performance has passed effectively waives the time stipulation. Once the stipulated time is waived, the obligation becomes to perform within a reasonable time. [22] Based on the factual matrix of the case, this court is of the considered view that the Defendant’s contention regarding late delivery is without merit. The delivery period was contingent on the receipt of government permits, and any potential delay was explicitly waived by the Defendant in writing. As such, the Defendant cannot now rely on this as a defence to his failure to make payment. [23] During the trial, the Defendant attempted to argue that his liabilities under the contract had been transferred to a third party, Empayar Paradigma, in 2019. This contention was raised during cross-examination but was not pleaded in the Defendant’s Statement of Defence. [24] It is well-established that a party is bound by its pleadings, and any attempt to introduce unpleaded issues constitutes unfairness to the opposing party. In Giga Engineering & Construction Sdn Bhd v Yip Chee Seng & Sons Sdn Bhd [2015] 6 MLJ 449, the Federal Court reiterated that a party cannot introduce issues not raised in pleadings as follows:- “[42] Now, it is trite law that the plaintiff is bound by its own pleadings (see R Rama Chandran v The Industrial Court of Malaysia & Anor [1997] 1 MLJ 145; Anjalal Anmal & Anor v Abdul Kareem [1969] 1 MLJ 22; Gimstern Corporation (M) Sdn Bhd & Anor v Global Insurance Co Sdn Bhd [1987] MLJ 302 (SC); Joo Chin Kia v Loh Seng Tek [1987]1 CLJ 194; KEP Mohamed Ali v KEP Mohamad Ismail [1981] 2 MLJ 10 (FC)), The plaintiff is not permitted to improve its pleading in any other manner other than by way of an application to amend. Otherwise it would be unfair and prejudicial to the defendants if the plaintiff could now be allowed to raise an issue that was not within the contemplation of the parties in the first place (see Esso Petroleum Co Ltd v South Port Corp [1956] AC 218, Playing Cards (M) Sdn Bhd V China Mutual Navigation Co Ltd [1980] 2 MLJ 182 (FC)).” [25] The Defendant is bound by his pleadings, and the introduction of new facts or defenses during trial is not permissible unless appropriately pleaded and substantiated. The involvement of Empayar Paradigma was never raised in the Defendant’s pleadings and thus cannot be considered in this case. [26] Further, the burden of proof lies on the party asserting the existence of a particular fact. Under Section 103 of the Evidence Act 1950, the burden of proof as to any particular fact lies on the party who wishes the court to believe in its existence. [27] Even if the argument of transfer of liability was properly pleaded, the Defendant failed to produce any contemporaneous documents or oral evidence to support this contention. [28] The Defendant had in fact admitted during cross-examination that there were no documents in the Bundle of Documents pertaining to Empayar Paradigma, nor were any physically produced in court. [29] The Defendant’s assertion that liability was transferred to Empayar Paradigma is entirely unsubstantiated and constitutes an afterthought. There is no evidence to support this claim, and the Defendant failed to meet the burden of proof required under the law. As such, this argument is dismissed. [30] The Defendant also alleged that he had not made payment to the Plaintiff because he had not yet received money from a third-party company at the shipyard. This claim was raised without any supporting evidence and contradicted by the Plaintiff’s correspondence with one Dato Asraf Destini, who confirmed that payment had already been made to the Defendant in 2019. [31] The Defendant’s oral testimony is directly contradicted by documentary evidence, specifically the email correspondence between the Plaintiff and Dato Asraf. The Defendant did not produce any evidence to substantiate his claim that payment was not received. [32] In Tindok Besar Estate Sdn Bhd v Tinjar Co [1979] 2 MLJ 229, the Federal Court emphasized the importance of contemporaneous documentary evidence in determining the veracity of a witness's testimony. When oral evidence contradicts contemporaneous documents, the court is more likely to rely on the latter. [33] The Defendant’s claim that he had not received payment from a third party is unsubstantiated and contradicted by contemporaneous documentary evidence. The court rejects this defense. [34] Based on the facts presented and the legal principles applicable to this case, the court finds that the Defendant had acted in breach of the Contracts by failing to pay the outstanding sums under the unpaid invoices. The Defendant’s consistent acknowledgments of debt and partial payments unequivocally demonstrate his liability. [35] Accordingly, the court orders that the Defendant pay the outstanding amount under the unpaid invoices to the Plaintiff, along with interest and costs. The Plaintiff is entitled to judgment in its favour for the sum claimed, and any applicable interest from the date of the breach until full payment is made. DAMAGES [36] The Plaintiff has claimed that, in addition to the outstanding sums under the unpaid invoices, the Defendant is also liable to pay interest on these amounts as per German law. Sections 286(3) and 288(2) of the German Civil Code (Bürgerliches Gesetzbuch, BGB) provide that a debtor is considered in default if they fail to perform within 30 days after the due date and receipt of an invoice or equivalent statement of payment. In such cases, the debtor is liable to pay an interest of nine (9) percentage points above the basic rate of interest from the date the payment became due until the payment is made. [37] As per the testimony of the expert witness, Dr. Dieter Hettenbach, the applicable rates of interest under German law during the relevant period are as follows:
