Banner Homes Group Plc v Luff Development Ltd [2000] Ch. 372
Constructive Trust – Oral Agreement – Joint Venture – Equity
Facts
The defendants, Luff Development Ltd, acquired a site that would be suitable for developing property on. Before this acquisition, the defendants made an agreement with the complainants, Banner Homes Group Plc, that they could develop this site as a joint venture. While there were many conversations and proposals between the companies, no written agreement was concluded. However, the defendants changed their mind about the agreement they had made with the complainants, but did not tell them in case they made a rival offer before they acquired the site.
Issues
The trial judge had dismissed the constructive trust claim based on the fact that there was no signed and written agreement between the parties. Banner Homes Group Plc appealed this decision and the issue in the case was whether this agreement amounted to a constructive trust.
Decision/Outcome
The appeal was allowed and the constructive trust claim was successful. Under equity it would not be right for the defendants to be the sole beneficial owner for the joint venture. The fact that the Luff Development Ltd did not want to inform the complainants indicates a prior agreement. Lord Justice Chadwick affirmed Pallant v Morgan and explained the elements where equity would come into play; when there is a pre-acquisition agreement although not always contractually enforceable, the non-acquiring party has some interest in the property, the acquiring party has not informed the other beforehand or has not honoured the arrangement and that the prior understanding gave the acquiring party an advantage to the detriment of the other.

This case summary remains accurate as a statement of the law on the Pallant v Morgan equity and constructive trusts arising from pre-acquisition agreements. The principles confirmed in Banner Homes Group Plc v Luff Developments Ltd [2000] Ch 372 continue to be applied by the English courts. The Pallant v Morgan equity has been considered and affirmed in subsequent cases, including Holiday Inns Inc v Broadhead and more recently in decisions applying the Banner Homes framework to joint venture disputes. There have been no statutory developments that displace or materially alter the equitable principles described. Readers should note that the boundaries of the Pallant v Morgan equity — particularly the question of what conduct short of a binding contract will suffice to trigger it — continue to be refined in case law, and the equity operates alongside (but remains distinct from) common intention constructive trusts in other contexts. Overall, the article provides a reliable summary of the core principles established by this case.
