When Equity Overrides the Small Print: The Privy Council’s Landmark Ruling on Just and Equitable Winding Up: Aquapoint LP (In Official Liquidation) v Xiaohu Fan

In a judgment with direct implications for Cayman Islands, BVI and English practitioners, the Privy Council has just made it significantly harder to use a carefully drafted partnership agreement as a complete shield against a just and equitable winding-up petition.

The Facts in Brief

AquaPoint LP was a Cayman Islands exempted limited partnership formed as a passive vehicle to hold shares in Legend Biotech Corporation ahead of its NASDAQ IPO. The general partner was GenScript Corporation, controlled by Dr Zhang. Dr Fan, a research scientist who had made a material contribution to the Legend business, held a 65.96% limited partner interest equivalent to 10% of Legend Biotech’s share capital.

Critically, Dr Fan had previously held an unqualified contractual right to that 10% shareholding under a separate 2016 agreement. He gave it up only because Dr Zhang and Ms Wang gave him repeated personal assurances that his entitlement would survive unchanged and that he would be able to access his shares six months after the IPO.

The partnership agreement contained two provisions that became central to the appeal. First, clause 7.7 provided that no limited partner could withdraw without the general partner’s prior consent, which could be withheld “for any reason (or no reason at all) in the sole and absolute discretion of the General Partner.” Second, entire agreement clauses stated that the agreement superseded all prior understandings and that Dr Fan had not relied on any representations in becoming a limited partner.

After the IPO lock-up expired, the general partner refused Dr Fan’s request for his shares. His winding-up petition was upheld at first instance, in the Court of Appeal, and by the Privy Council.

Finding 1: Quasi-Partnership Is an Example, Not a Precondition

For decades, practitioners and courts have treated the existence of a quasi-partnership as effectively a threshold requirement for equitable intervention in the just and equitable jurisdiction. If a petitioner could not bring his case within Lord Wilberforce’s three indicia in Ebrahimi v Westbourne Galleries (personal relationship with mutual confidence, participation in management, and restriction on transfer) his petition was in serious difficulty. The Privy Council has now authoritatively corrected that reading.

The Board held that Lord Wilberforce’s three indicia were illustrative rather than exhaustive or definitional. The true underlying principle is broader: the just and equitable provision enables the court to subject the exercise of legal rights to considerations of a personal character arising between one individual and another which make it inequitable to insist on those rights. On the facts, the Board expressly found that Aquapoint did not have the characteristics of a quasi-partnership. It was a passive holding vehicle with no agreement that any partner other than the general partner would participate in the business. Yet the winding-up order stood.

The practical takeaway is that petitioners are no longer required to shoehorn their case into the quasi-partnership framework. What matters is the quality and directness of the personal circumstances that make the exercise of legal rights inequitable in the specific case. The Board was nonetheless careful to note that the facts here were “very unusual.” This is not an open invitation to petition, and the threshold outside the established categories remains high.

Finding 2: Entire Agreement Clauses Cannot Alone Defeat the Jurisdiction

Respondents to winding-up petitions have routinely deployed entire agreement clauses and non-reliance provisions as what amounts to a knock-out point. If the petitioner contractually acknowledged that he was not relying on representations, how could he invoke equity? The Privy Council has held that this argument, while highly relevant, is not decisive.

The Board’s reasoning deserves to be understood precisely. It was not holding that entire agreement clauses are generally ineffective in the winding-up context. It was holding that they cannot be decisive where the agreement containing them was itself entered into on the basis of the very assurances relied upon. To allow the instrument to be used to extinguish the assurances that induced it would be internally contradictory. The Board assumed, without deciding, that the clauses may well have prevented a contractual claim; that is, however, a different question from whether they oust the equitable jurisdiction entirely.

The practical takeaway is twofold. For petitioners, an entire agreement clause is no longer a reason to abandon a petition without first analysing the underlying circumstances. For respondents and those advising on the drafting of partnership agreements, entire agreement clauses remain relevant and will often be determinative, but they cannot be relied upon as a complete answer where the antecedent assurances go to the root of why the petitioner entered the agreement in the first place.

Finding 3: The Statutory Source of Jurisdiction Is Section 36(3)(g) of the ELP Act

There had been a persistent debate in the Cayman courts at first instance as to whether the just and equitable jurisdiction to wind up an ELP arose under section 35(e) of the Partnership Act (via section 3 of the ELP Act) or under section 92(e) of the Companies Act (via section 36 of the ELP Act). The Board, while noting that it had received no submissions on the point, expressed a clear view that the answer is simpler than either. The power arises directly and solely under section 36(3)(g) of the ELP Act itself, which provides in terms that the court may make orders for the winding up and dissolution of an ELP as may be just and equitable. No further statutory chain is required.

This conclusion is obiter, but it is a Privy Council obiter observation and will carry significant authority in the Cayman courts. It resolves a procedural uncertainty that had added unnecessary complexity to petitions.

Finding 4: A Derivative Action Is Not an Adequate Alternative Remedy in This Context

Respondents in winding-up petitions frequently argue that alternative remedies are available and that the petitioner is acting unreasonably in not pursuing them. The Board rejected the suggestion that a derivative action against the general partner for breach of its section 19(1) good faith duty was an adequate remedy for Dr Fan.

The reasoning is instructive. Section 19(1) directs the general partner’s duty to the ELP as a whole rather than to individual partners in respect of personal assurances given to them. A derivative action would, at best, deliver a remedy to the ELP and could not therefore provide Dr Fan with personal relief. This is an important limitation on the derivative action route in ELP disputes and narrows the alternative remedy arguments available to respondents in cases involving personal assurances made to individual partners.

The Broader Message

Aquapoint does not destabilise offshore fund structures or ELPs generally; the Board was at pains to say so. It does, however, serve a clear warning. Where a party is induced to give up pre-existing rights and enter a carefully documented structure on the basis of personal assurances, the documentation alone will not necessarily protect against a winding-up order. The quality of the human relationship and the circumstances in which the structure was created remain firmly in play.
