The Appellant argues that the applicable law of the Counterclaim would be either Vietnamese or Cambodian law. The governing law of the MOU, which is in question in the Counterclaim, is likely to be Vietnamese law. The factors pointing to Vietnamese law are that the MOU was to be signed in Vietnamese in Vietnam, in respect of obligations to be performed either in Vietnam or Cambodia. For the claim in fraudulent misrepresentation, the place of the tort was Vietnam, and a presumption arises that the applicable law is Vietnamese. Turning to the governing law for breach of trust or unjust enrichment, this is again said to be either Vietnamese or Cambodian law; but there is doubt as to whether claims in equity are capable of being pursued under Vietnamese or Cambodian law. Finally, in so far as the transfer agreement is relevant, its governing law would be Vietnamese law under the choice of law clause in clause 8.7 of that agreement, the choice of seat of arbitration was Vietnam, and the contract is in Vietnamese. There are significant differences between Singapore and Vietnamese and Cambodian law as the former is a common law system while the latter are civil law systems. It is sufficient for the Appellant to show that there are potential complications in the application of Vietnamese or Cambodian law by Singapore courts. Experts called in relation to the Appellant’s claim would not necessarily be those for the MOU. It is more procedurally convenient for the counterclaim to be heard in Vietnam or Cambodia, as the relevant lawyers would be able to submit directly on the matters arising. Unnecessary time and expense would be incurred to appoint Vietnamese and Cambodian law experts for proceedings in Singapore.
