2.27 No redistribution of risk allocation by contract. Generally speaking, in the absence of any vitiating factors such as fraud, duress or misrepresentation resulting in any agreement being avoided ab initio, and where the agreement has not been frustrated due to impossibility of performance, the agreement between the parties should not be disturbed, and the courts should not invoke the law or restitution and unjust enrichment to redistribute risks which have been allocated by the mutual agreement of the parties.”. [35] As propounded by the Federal Court in Dream Property Sdn Bhd v Atlas Housing Sdn Bhd [2015] 2 CLJ 453, the law of unjust enrichment is recognised by which justice is done in a range of factual circumstances and the restitutionary remedy is applied to attain justice. Nonetheless we observed that in Dream Property, the law of unjust enrichment was articulated under the context of ‘The Relief Questions’. This is what the Federal Court said: “[93] So far we have dealt with the issue pertaining to the liability questions. We conclude that the defendant only paid 10% deposit of the purchase price and failed to pay the balance of the purchase price even though obliged to do so under the SPA. As correctly decided by the High Court and the majority of the Court of Appeal, the plaintiff had, in our judgment, validly terminated the SPA. [94] This brings us to the relief questions. Civil Appeal No. W-02(C)(W)-1200-06/2017 12 The Relief Questions Unjust Enrichment and Restitution [95] To a large extent, this issue deals with the restitution that the defendant claims it is entitled to, over and above the costs of construction of the mall, under the law of unjust enrichment.”. [36] The decision of the Federal Court in Dream Property in our view is of no assistance to the respondent. In Dream Property, the Federal Court did not move away or disregard the sanctity of contract between the parties as can be seen below: “[107] … The critical issue that needs to be addressed is what constitutes unjust enrichment and undue benefit, and in what manner should a purchaser of vacant land granted restitutionary relief when he has constructed a building on the said piece of land pursuant to and expressly permitted by a contract between him and the vendor.”. [37] We therefore agreed with the appellant that the learned judge erred in law in that his Lordship’s decision is akin to allow the law of unjust enrichment to displace, defeat, override and/or undermine the clear terms of the subcontract between the appellant and the respondent. [38] We therefore resolved the issue in favour of the appellant. The respondent cannot subvert the subcontract and in this regard, we agreed with the appellant that the respondent was not entitled to RM11.4 million of the arbitration award simpliciter without having to prove anything at all on the value of the works done. The evidence revealed that the draft final account between the appellant and the respondent had never been resolved during the last meeting between the parties. There was no evidence that the Civil Appeal No. W-02(C)(W)-1200-06/2017 13 quantitative amount of the works done by the respondent pursuant to the subcontract had been agreed by both parties before or after the commencement of the arbitration. Equity cannot eclipse the subcontract and the respondent cannot claim RM11.4 million as a matter of convenience, in total disregard to the sanctity of the subcontract. [39] The respondent took the position that the appellant had been enriched because it was not the appellant that had completed the works. That may be so, and indeed MJE had commenced action against the appellant in the first suit. It must be highlighted that in the first suit, MJE’s claim was also premised on the same arbitration awards. The first suit was dismissed on inter alia, the ground of limitation. The respondent, being privy to MJE would be caught by res judicata and issue estoppel as far as limitation is concerned. It was held by the Federal Court in Asia Commercial Finance (M) Bhd v Kawal Teliti Sdn Bhd [1995] 3 MLJ 189 that when a matter between two parties has been adjudicated by a court of competent jurisdiction, they and their privies are not permitted to litigate once more the matter that had been adjudicated, as the judgment becomes the truth between such parties. (see also the cases of Letchumanan a/l Gopal (representative of the estate of Rajammah a/p Muthusamy, deceased) v Pacific Orient & Co Sdn Bhd [2011] 6 MLJ 788 and Dato’ Sivananthan a/l Shanmugam v Artisan Fokus Sdn Bhd [2016] 3 MLJ 122 which set out the principle that the doctrine of res judicata also applies to a non-party). On this ground, the claim for unjust enrichment ought to have been dismissed by the learned judge. The respondent could not use its claim for unjust enrichment as a tool to circumvent the law on limitation. Civil Appeal No. W-02(C)(W)-1200-06/2017 14 [40] Further, we agreed with the appellant that the arbitration awards were the direct result of the legitimate arbitration process between the appellant and the Government pursuant to the main contract, which is a separate and distinct contract from the subcontract between the appellant and the respondent. The respondent’s right of claim against the appellant remained intact for 6 years from the date of the termination of the subcontract i.e.
