What happened?
The case involved a supply contract between URE (a start-up energy provider) and Genesis, a housing association. The parties planned to enter into a 25-year deal, but entered into an interim four-year contract, to allow more time for URE to secure the necessary investment and to negotiate the long-term arrangement.
A few months in, Notting Hill merged, by way of amalgamation, with Genesis, creating Notting Hill Genesis ("NHG"), notifying URE after the fact, but crucially, without asking for its approval.
A year into the four-year contract, the relationship between the parties deteriorated, with NHG signalling that it was pulling out of the longer term arrangement, prompting URE to seek urgent legal advice. This advice revealed a termination clause that, although largely consisting of conventional insolvency-related triggers, also provided for a change of control right, triggered by the merger with Notting Hill. This entitled URE not only to terminate, but also to claim a substantial termination payment from NHG.
NHG argued that URE had known about the merger for six months and had waived its right to terminate by continuing under the contract. The Court of Appeal disagreed, ruling that a party cannot waive rights it does not know it has, and in complex contracts, businesses cannot be expected to be alive to every technical detail without legal input.
