Awareness of illegality does not entirely preclude the remedy of restitution under section 66. The mere fact that parties were aware of the agreement’s illegality does not necessarily bar relief under section 66. [45] These principles are found in the following passages of the Detik Ria judgment, articulated by Nallini Pathmanathan FCJ: [134] Indeed, in Tan Chee Hoe & Sons Sdn Bhd v. Code Focus Sdn Bhd [2014] 3 CLJ 141; [2014] 3 MLJ 301, the Federal Court granted s. 66 relief despite the fact that both parties had knowledge of the illegality, namely the contravention of s. 132C of the Companies Act. (See also: Paragon Union Bhd v. Prestamewah Development Sdn Bhd & Anor And Another Case [2018] CLJU 1049; [2018] 1 LNS 1049; [2018] MLJU 711). [135] Generally, our courts have taken the position that in order to invoke s. 66, parties are required to have no knowledge of the illegality. To that end, parties are required to come to court with clean hands in order to succeed in a claim under s. 66. In an article entitled 'Relief For Claims Based on Contracts Tainted by Illegality' on Lex; In Breve, University of Malaya Law Review, Choong Shaw Mei, lecturer at the Faculty of Law, University of Malaya, examines the premise for the application of s. 66 in considerable depth. [136] As pointed out by the learned author, the requirement for the absence of knowledge of the illegality was not the position taken in the days when s. 66 was known as s. 65 of the Contract Enactment 1899 ('the Contract Enactment’). In support of this, reference is made to the case of Khem Singh v. Anokh Singh [1930] 1 LNS 2. In that case, Elphinstone CJ disagreed with the then-prevailing view of the Indian Courts at the time, stating: The Indian Courts have taken the view that the words discovered to be void limit the operation of the section to cases where a contract is found to be void by reason of some facts not known to the parties at the date of the contract, but subsequently discovered? With the greatest respect to the Indian Courts I feel unable to adopt that view. The words "when an agreement is discovered to be void" are in general terms. The section is silent as to when or by whom or for what reason the agreement is to be discovered to be void. In my opinion the words "discovered to be void" would mean no more than "if found to be void". In the course of this suit the Court has found the agreement sued upon to be void. In this sense the agreement has been discovered to be void, and section 65 seems to be exactly applicable. (emphasis added) ………… [139] However, this decision was not followed subsequently by the Federal Court, and in Menaka (the appeal to the Privy Council from the Federal Court case of Ng Siew San v. Menaka [1973] CLJU 99; [1973] 1 LNS 99; [1973] 2 MLJ 154), the Privy Council agreed, without much reasoning, with the Federal Court's interpretation of 'discovered to be void' as meaning that both parties were unaware of the illegality. As pointed out by the learned author, the Privy Council then appears to have melded or combined the principle of restitution with the principle underlying s. 66 by stating: The principle underlying both sections [Section 65 of the Indian Contracts Act and our Section 66] is the same, and it is that "a right to restitution may arise out of the failure of a contract though the right be not itself a matter of contractual obligation. [140] The result is that most case law in this jurisdiction takes the position that parties should not be in pari delicto and the illegality of the agreement must be discovered subsequent to the date of the contract. The somewhat varied positions taken in relation to s. 66 makes the legal position less than absolutely clear. ………………… [142] However, in Yeep Mooi v. Chu Chin Chua & Ors [1960] CLJU 169; [1960] 1 LNS 169; [1981] 1 MLJ 14, the Federal Court speaking through Salleh Abas FJ held to the contrary and reverting to its original interpretation of s. 66 held that: In our view this case fits in squarely with the words of section 66 as an agreement which is "discovered to be void" does not mean that the contract is void on discovery or void because of discovery of illegality. It means what it says, in that the contract was void ab initio without the parties at the time being aware of the true legal position. It is only later that the contract is found to be void and so they became aware of its voidness. We are of the view therefore that section 66 of the Contracts Act applies to this and the appellant is entitled to the restitution of her money by the pawnshop which received an advantage from its use. (Menaka v. Lum Kum Chum [1976] CLJU 181; [1977] 1 MLJ 91). (emphasis added) [143] In the varied positions adopted by our courts over the years it would appear that the original position adopted by Elphinstone CJ in Khem Singh v. Anokh Singh (above) has considerable appeal. Section 66 was given a broad construction allowing for the remedy of restoration or restitution to the status quo ante in a suitable case. What is key to Elphinstone CJ's interpretation of s. 66 (then s. 65) is that knowledge of the parties does not necessarily bar a s. 66 remedy. Secondly, it was construed as being applicable in cases where the contract is void ab initio. This also accords with s. 66 appearing in Part V of the Contracts Act 1950, which relates to the 'Performance of Contracts' and statutorily prescribes it as a remedy where a contract is discovered to be void, without any reference to knowledge of the parties. This is a codified statutory remedy available where the contract is void and ought not to be stultified unnecessarily, particularly when there is no express preclusion of the remedy to cases where there was knowledge of the illegality as of the date of the contract. Put simply, knowledge of the illegality is not a complete bar to the s. 66 remedy. [144] This is also in accord with the early historical position in the common law as referred to by Lord Sumption in Patel, where the restoration of benefit was viewed as ensuring that the persons who procured an advantage or benefit by virtue of an illegality or an illegal transaction were not allowed to retain possession of the same as that would be contrary to principles of equity and fair play. [145] This may appear to be at odds with what the courts have pronounced in the cases of Singma Sawmill and Triple Zest Trading & Suppliers & Ors v. Applied Business Technologies Sdn Bhd [2023] 10 CLJ 187; [2023] 6 MLJ 818 ('Triple Zest'). However, these are cases where the illegality was one that struck at the core primary obligations of the transactions under their respective statutes. In Singma Sawmill, for instance, the landlord violated an express and clear condition on the title; indeed, the breach was so intentional that Raja Azlan Shah CJ termed it 'wilful, if not contumacious'. His Lordship also clearly regarded the appellants in that case as using the subject matter of the agreement for an 'unlawful purpose'. [146] It is noteworthy that in interpreting the decision in Singma Sawmill, the Federal Court in CME Group Bhd v. Bellajade Sdn Bhd & Another Appeal [2018] 10 CLJ 147; [2019] 1 MLJ 141, took note of the uniqueness of the facts of that case ………….. [147] To this extent, Singma Sawmill ought to be construed in the context of its particular facts. [Emphasis added] [46] The Federal Court provided the following guidance regarding the granting of restitution under section 66 CA 1950 (“Detik Ria Guidelines”): How Is Section 66 To Be Applied? [148] Therefore, the grant of the s. 66 remedy warrants the formulation of a guide to determining whether the s. 66 remedy is engaged or not. Where a contract is 'discovered to be void' or 'becomes void', the guidelines for the application of s. 66 are as follows. [149] First, the centrality of the illegality in the statute is to be considered. This is a matter of construction of the particular statute. [150] Second, the proportionality of denying s. 66 relief to the illegality should be considered. There are numerous factors which should be considered in assessing proportionality.
