That the learned JC had erred in failing to hold that the respondents were barred by issue estoppel from raising the issue of unclean hands, and in failing to hold that it was an abuse of process to do so. [18] The question for our determination was whether the learned JC was right in allowing the 1st and 3rd respondents to raise the issue of unclean hands by way of a preliminary objection, or whether the issue was res judicata. [19] There is no dearth of authority on the point. Suffice it if we refer to four of them. First, Government of Malaysia v Dato Chong Kok Lim [1973] 2 MLJ 74 where Sharma J held at page 76: “A decision given by a court at one stage on a particular matter or issue is binding on it at a later stage in the same suit or in a subsequent suit. (See Peareth v Marriott, Hook v Administrator-General of Bengal and Others and In the matter of the Trusts of the Will of Tan Tye (Deceased) Yap Liang Neo v Tan Yew Ghee and Another. Parties cannot raise a second time in the same suit an issue that has already been determined either expressly or by necessary implication. (See Louis Dreyfus v Arunachala Ayya).” (emphasis added) [20] Second, Tenaga Nasional Bhd v Prorak Sdn Bhd & Anor [2000] 1 MLJ 479. Gopal Sri Ram JCA (as he then was) delivering the judgment of the court quoted with approval the following pronouncements by Wigram VC in Henderson v Henderson [1843] All ER Rep 378 at pages 381-382: “[W]here a given matter becomes the subject of litigation in, and of adjudication by, a court of competent jurisdiction, the court requires the parties to that litigation to bring forward their whole case, and will not (except under special circumstances) permit the same parties to open the same subject of litigation in respect of matter which might have been brought 8 forward as part of the subject in contest, but which was not brought forward only because they have, from negligence, inadvertence, or even accident, omitted part of their case. The plea of res judicata applies, except in special cases, not only to points upon which the court was actually required by the parties to form an opinion and pronounce a judgment, but to every point which properly belonged to the subject of litigation and which the parties, exercising reasonable diligence, might have brought forward at the time.” (emphasis added) [21] Third, Hong Leong Bank Bhd (previously known as Credit Corp (M) Bhd) v Sheikh Ahmad Marzuki bin Sheikh Yusof [2015] 2 MLJ 12. In that case the respondent filed an application to rescind the receiving order and adjudication order on the ground that the loan had been fully settled. The application was dismissed by the registrar and the respondent appealed to the judge but subsequently withdrew the appeal. [22] Some months later, the respondent again filed an application to annul and rescind the receiving order and adjudication order, which was again dismissed by the registrar. However, on appeal to the judge, the appeal was allowed. On further appeal to this court, it was held that the respondent was estopped, pursuant to the principle of res judicata, from re-litigating the issues of annulment and rescission of the adjudication order and receiving order and the expungement of the proof of debt admitted by the Director General of Insolvency under the conventional loan. This is what the court said at page 21: “the respondent had the opportunity to fully ventilate his case before the learned judge in chambers in the hearing of his appeal against the decision of the learned registrar in encl 12A but had instead chosen to withdraw his appeal. The same cause of action may not be relitigated between the same parties as it is res judicata. It is trite that the respondent cannot litigate by instalments;” 9 [23] Last but not least, the decision of the then Supreme Court in Asia Commercial Finance (M) Bhd v Kawal Teliti Sdn Bhd [1995] 3 MLJ 189 where it was held as follows at page 200: “There is one school of thought that issue estoppel applies only to issues actually decided by the court in the previous proceedings and not to issues which might have been and which were not brought forward, either deliberately or due to negligence or inadvertence, while another school of thought holds the contrary view that such issues which might have been and which were not brought forward as described, though not actually decided by the court, are still covered by the doctrine of res judicata, ie doctrine of estoppel per rem judicatum. We are of the opinion that the aforesaid contrary view is to be preferred; it represents for one thing, a correct even though broader approach to the scope of issue estoppel. It is warranted by the weight of authorities to be illustrated later. It is completely in accord or resonant with the rationales behind the doctrine of res judicata, in other words, with the doctrine of estoppel per rem judicatum. It is particularly important to bear in mind the question of public policy that there should be finality in litigation in conjunction with the exploding population; the increasing sophistication of the populace with the law and with the expanding resources of the courts being found always one step behind the resulting increase in litigation.” (emphasis added) [24] This authority binds us and all courts below us. We were therefore constrained by the doctrine of stare decisis to agree with learned counsel for the appellants that res judicata or issue estoppel would apply to the issue of unclean hands raised by the 1st and 3rd respondents. [25] On the facts and having regard to the authorities, it was clear to us that the issue of unclean hands raised by the 1st and 3rd respondents in the court below was res judicata. We do not think it was open to the 1st and 3rd respondents to argue before us in the present appeal that the issue of unclean hands was not before this court at the hearing of the appellants’ 10 appeal on 12.11.2014 and could therefore be raised again before the learned JC by way of a preliminary objection. [26] Paragraphs 23 and 31 of the 3rd respondent’s written submissions which it filed for purposes of the appeal on 12.11.2014 provide enough proof that the issue was indeed raised at the hearing and had been decided upon by this court. It was for this reason that we allowed the appellants’ appeal with costs, subject to payment of the allocator fee.
