(vi) If the property was not sold, the parties were to enter into further discussions regarding the treatment of monies paid by the plaintiff and/or the second defendant to the first defendant. [14] A further sum of RM16,500,000.00 was paid by the plaintiff to the first defendant under the SA. [15] As a result, the plaintiff paid the first defendant RM56,250,000.00 in respect of the purchase of the property, leaving a balance of RM38,750,000.00 to be paid. [16] Due to the plaintiff's inability to meet the additional payments provided for in the SA, the first defendant terminated the SPA as provided in Clause 1.7(A) of the SA and terminated the Management Agreement by way of a letter dated 1 August 2018 ("Termination Notice"). [17] On 1 September 2018, the plaintiff returned vacant possession of the property to the first defendant. [18] A change of event then occurred. [19] It was agreed by the first defendant on 29 January 2019 that the Termination Notice would be rescinded, the SPA and Supplemental Agreement would be revived, and that the second defendant would replace the plaintiff as purchaser under the SPA and SA, provided a Deed of Novation Cum Variation was executed by the parties and subject to their terms. [20] Under the terms of the Deed of Novation Cum Variation dated 12 February 2019 ("DNCV"), the SPA and the SA were novated, whereby the second defendant replaced the plaintiff as purchaser. [21] The DNCV provided that the current balance of the purchase price then due to the first defendant was RM38,750,000.00. Here, RM56,250,000.00 had already been paid by the plaintiff to the first defendant in calculating the balance purchase price payable to the first defendant by the second defendant. [22] As far as the plaintiff is concerned, the DNCV was silent about the return of the sum of RM56,250,000.00 or any excess portion thereof in the event of the termination of the DNCV, SPA, and/or SA. [23] Despite these arrangements and agreements, the plaintiff commenced litigation against the first and second defendants at the Kuala Lumpur High Court with suit number WA-22NCvC-499 07/2019 ("Suit 499") seeking to rectify the DNCV. [24] In light of Suit 499's filing, the first defendant terminated the SPA and the SA on 6 February 2020. Court's analysis and findings [25] In support of their applications, the defendants argue that this action should be dismissed on the basis that it is res judicata. The reason is that a similar action has already been filed by the plaintiff and dealt with right up to the Federal Court under the same cause of action and with the same parties involved. [26] In this regard, the defendants argue that the facts set up by the plaintiff in this present action before this court revolve around the entry into the SPA, SA, and DNCV for the purchase of the property. [27] However, the defendants further argue that a similar cause of action had already been decided by another High Court in Suit 499, which had also been affirmed by the Court of Appeal. Moreover, the plaintiff had even been denied leave to appeal by the Federal Court. [28] On the basis of the following, the defendants contend that the plaintiff's initial relief in Suit 499 was a declaration that the SPA, SA, and DNCV were void, invalid, and of no effect. First, the plaintiff was unduly influenced by the first defendant into signing the SA, which was executed without their consent. Second, the first defendant altered clause 7.1 of the SPA in a way that was oppressive, unreasonable, unconscionable and unfair. Third, the plaintiff's board did not pass a resolution authorising it to execute the SA. Fourth, as for the SA, only clause 2 of the SA was supported with consideration. Fifth, there was no consideration for the DNCV. Finally, the SA and DNCV were supported by past consideration and/or insufficient consideration. [29] According to the defendants, the plaintiff amended its Statement of Claim in Suit 499 on 9 March 2019, seeking rectification of the DNCV and return of RM56,250,000.00. First, they claim the defendants breached implied terms in the DNCV by failing to return RM56,250,000.00 paid by the plaintiff. Second, the plaintiff argues that there had been a mutual mistake between the parties to include a provision in the DNCV requiring the plaintiff to return RM56,250,000.00, which means that the DNCV does not reflect the parties' true intentions and should be amended. In addition, the plaintiff raised the claim that the defendants have been unfairly enriched since the defendants were unable to justify their retention of the RM56,250,000.00 paid by the plaintiff. [30] Following the defendants' arguments in relation to Suit 499, the defendants now analyse the current suit before the court. According to the defendants, the causes of action here are similar to the causes of action in Suit 499. In the Statement of Claim before this court, the plaintiff asserted that the DNCV does not provide for the first defendant to retain the sum of RM56,250,000.00 paid by the plaintiff or for the excess to be released to the second defendant. Moreover, the plaintiff here asserts that no consideration was provided for the retention of RM56,250,000.00. Therefore, it is the plaintiff's claim that RM56,250,000.00 would be unjustly retained by the defendants. [31] According to the defendants, the plaintiff is taking such a position now simply because it has now contended that since the property has not been sold after the expiration of five years from the date of redelivery of vacant possession to the first defendant, the plaintiff is entitled, pursuant to clause 1.7(A), to claim for the excess of the sale of the property by the first defendant to any third party. As a result, the plaintiff requested a discussion with the first defendant about reimbursing the excess. This is how the current action came to be. [32] Accordingly, the defendants now assert that since Suit 499 dealt with similar facts and causes of action to those before this court, this action has become res judicata, and that issue estoppel barred the plaintiff from pursuing its claim further in this case. Because of this, the defendants argue that the plaintiff should not be allowed to relitigate the same causes of action and issues. [33] In opposing the two applications, the plaintiff asserts that the principle of res judicata does not apply. This is due to the fact that the SPA and SA have since been terminated by the first defendant. Comparatively, in the plaintiff's previous action, the SPA and SA were not terminated at the relevant time. [34] The plaintiff alleges that its claim now arises out of the claim for money had and received pursuant to clause 1.7(A) of the SA. The reason for this is that due to the termination of the SPA and SA by the first defendant, the first defendant was enriched in the amount of RM56,250,000.00 less permitted deductions. According to the plaintiff, the first defendant's enrichment was at the expense of the plaintiff, who paid the defendant that sum. Consequently, the plaintiff believes it is unjust for the first defendant to retain RM56,250,000.00 after terminating the SPA and SA against the second defendant. Thus, the plaintiff argues there is no defence available to the first defendant to limit or extinguish its responsibility to make restitution. [35] Furthermore, the plaintiff argues that Suit 499 is completely different from this current suit on the basis of the respective cause of action. In Suit 499 the plaintiff had initially initiated a legal action against the defendants to seek rectification of the DNCV on the grounds that the DNCV failed to provide or to seek return of the sum of RM56,250,000.00 or any excess portion thereof to the plaintiff in the event of a termination. [36] Further, the plaintiff claims that Suit 499 was filed prematurely on 16 July 2019 before termination of the SPA and SA. Therefore, it is the plaintiff's case now that the right to seek a refund for the sum of RM56,250,000.00 under clause 1.7(A) of the SA did not arise at the time Suit 499 was filed because it requires the termination of the SPA and SA in order for clause 1.7(A) of the SA to become operative. As such, the plaintiff forcefully argues that from a legal point of view, the plaintiff could not have properly sought any relief relating to clause 1.7(A) of the SA by way of Suit 499 because clause 1.7(A) was only enforceable after Suit 499 was filed on 6 February 2020. [37] According to the plaintiff further, the property was not sold within the five (5) years prescribed by clause 1.7(A) of the SA, so the parties had to engage in further discussions to resolve the treatment of the monies paid by the plaintiff or the second defendant to the first defendant, in which case the first defendant must refund the plaintiff RM56,250,000.00 (less permitted deductions). To this end, the plaintiff claims that since the first defendant has taken a position through its solicitor that it is not agreeable to attend the discussion and meeting for parties to determine the total sum of deduction and the timeline for the refund of the excess sum to the plaintiff, this action is well justified. [38] The above reflects the positions taken by the parties. [39] Pursuant thereto, the following is my analysis and findings on the issues posed by these two applications.
