Matthew Halstead Cobden v Daniel Halstead Cobden

On dissolution of a partnership, an open-market sale is the normal method of realising assets under the Partnership Act 1890, but it is not an absolute rule. A Syers order may be made where a sale would fail to achieve full value or would be unfair. Exceptional circumstances do not require a rigid jurisdictional threshold or an exhaustive recognised category.

An equity akin to proprietary estoppel can justify a buy-out order where assurance, reliance and detriment establish unconscionability, even though the claimant already owns an interest and seeks control of its disposal. Reliable expert valuation, including an appropriate margin and sale-cost savings, can support the order. The possibility of a higher market price is not an absolute bar. Appellate intervention on fact or evaluation requires an identifiable flaw or an unsustainable conclusion.

Matthew and Daniel Cobden were equal partners in a farming business carried on under a partnership at will. After their relationship broke down, Matthew dissolved the partnership and sought an order requiring Daniel to sell his interest to Matthew at a value fixed by expert evidence rather than through an open-market sale. The High Court made a Syers order on the basis of a proprietary-estoppel-like equity, finding a shared understanding, detrimental reliance and unfairness in liquidation: [2024] EWHC 1581 (Ch).

Daniel appealed, arguing that [2024] EWCA Civ 605 restricted Syers orders to exceptional categories, that the equity had not been established, and that expert valuation was inadequate. The central issues were whether such an equity could justify departure from the normal sale and whether the judge’s findings and valuation approach were open to appellate challenge.

1. Appeal dismissed unanimously. Newey LJ gave the leading judgment. Nugee LJ agreed, and Lewison LJ agreed with the result and reasoning.
2. On dissolution, Partnership Act 1890, section 39 makes an open-market sale the normal means of maximising the realised value of partnership assets. There is no absolute rule requiring a sale. A Syers order may be made where an open-market sale would not achieve full value or would be unfair: Syers v Syers (1876) 1 App Cas 174; Bahia v Sidhu [2024] EWCA Civ 605, [2025] Ch 55.
3. The exceptional nature of the relief does not impose a rigid jurisdictional threshold or require strange, unusual or previously recognised circumstances. The categories identified in Bahia were examples, not an exhaustive list. The operative question was whether departure from the normal sale was necessary to serve the interests of justice and avoid unfairness or injustice.
4. An equity akin to proprietary estoppel could justify a Syers order. The relevant matters were assurance, reliance and detriment, informed by the equitable concern to prevent unconscionability and assessed in the round. Proprietary estoppel principles could affect the disposal of an existing proprietary interest, not merely confer title. The judge was entitled to find a continuing shared understanding that Matthew would buy Daniel out at a fair value, reliance through the development of the business, detrimental reliance and unfairness in ordering liquidation. Tax consequences, the position of Gill and possible effects on farm workers reinforced that conclusion.
5. The appellate court was not entitled to re-evaluate the evidence or evaluative conclusion afresh. Intervention required an identifiable error, a critical finding unsupported by evidence, a failure to consider material evidence, a gap in logic or a conclusion that could not reasonably be explained or was rationally insupportable. The judge’s failure to mention a particular point did not establish that it had been overlooked: Piglowska v Piglowski [1999] 1 WLR 1360; Henderson v Foxworth Investments Ltd [2014] UKSC 41, [2014] 1 WLR 2600; Volpi v Volpi [2022] EWCA Civ 464, [2022] 4 WLR 48; In re Sprintroom [2019] EWCA Civ 932, [2019] 2 BCLC 617.
6. The possibility that an open-market sale might produce a higher price was not an absolute bar. The valuation evidence was sufficiently reliable, and the valuation margin and savings in sale costs provided additional protection. The Syers order was therefore within the judge’s discretion.

• Court of Appeal (Civil Division): Appeal dismissed. The High Court’s Syers order was upheld. [2025] EWCA Civ 1612.
• High Court (Chancery Division): HHJ Russen KC made a Syers order requiring Daniel’s partnership interest to be bought out at a value fixed by expert valuation, relying on an equitable basis for departing from an open-market sale. [2024] EWHC 1581 (Ch).
