⁷⁶ The Court of Appeal in Geok Hong Co did not revisit the question as to whether Singapore law should follow the Stack approach.

⁷⁷ The company did not rely on Mr Tan's lack of authority to resist the common intention constructive trust claim in the lower court, though the argument was raised before the Court of Appeal. See Geok Hong Co, above n 40, at [41].

⁷⁸ The relationships in these two cases attracted the operation of the presumption of advancement.

⁷⁹ As the parties did not argue on the basis of common intention constructive trust and did not appear to submit on the applicability of the Stack approach under Singapore law, the Singapore Court of Appeal's ‘rejection’ of the Stack approach in Chan Yuen Lan constituted obiter observation. Nevertheless, the Court of Appeal had dedicated 51 paragraphs in its judgment to discussing the merits of the Stack approach ([101]–[142]) and explicitly discussed whether Singapore law should adopt the same approach ([151]–[159]). The Chan Yuen Lan framework of analysis was clearly propounded on the basis of the in-depth discussion and on the perceived merits of the minority judgment delivered by Lord Neuberger in Stack. The obiter ‘rejection’ of the Stack approach in Chan Yuen Lan was thus authoritative and, notably, property disputes brought before the Singapore courts after Chan Yuen Lan applied the Chan Yuen Lan framework of analysis.

⁸³ As the alleged oral representation was not proved, the alternative claim on proprietary estoppel also failed (Geok Hong Co, above n 40, at [95]). Moreover, the court did not think that detrimental reliance was established on the facts of the case.

⁸⁵ See Tahir v Faiz [2019] EWHC 1627 (QB). The English High Court applied the resulting trust analysis, instead of the common intention constructive trust analysis.

⁸⁶ See Smith v Bottomley [2013] EWCA Civ 953. There are issues as to whether the representor has authority to make the oral representations on behalf of the company and whether the corporate veil could be pierced. Where the representor has contributed to the purchase price of the property, a resulting trust analysis may be applied to determine the representor's interest in the property without having to pierce the corporate veil: see Prest v Petrodel [2013] 2 AC 415. In Geok Hong Co, however, it was not clear if the 10% deposit was paid for by the patriarch (Mr Tan) or the company. The trial court found that the remaining 90% of the purchase price was paid for by Mr Tan but it was unclear if he did so in his personal capacity or on behalf of the company. In any event, neither party to the dispute contended that the property was held on a resulting trust for Mr Tan. See Geok Hong Co, above n 40, at [21].

¹¹² As explained in Ng So Hang, above n 37, at [46], that parties ‘intended for the right of survivorship to operate upon the demise of one party in deciding to hold the Property as joint tenants’ did not mean that ‘the parties also intended for the beneficial interest to be held in equal shares, or in any particular proportion while both parties were alive’. In other words, Singapore law appears to permit joint owners to use joint tenancy for different purposes: (1) joint tenancy as in the joint owners holding the whole interest in the property with no separate shares even while the joint owners are alive; or (2) joint tenancy for the pragmatic purpose of enabling the operation of right of survivorship on the demise of a joint tenant for passing the property to the other joint tenant but the joint tenants are to hold the property as equitable tenants in common while both are still alive and in accordance with their contributions to the purchase price.
