Key Facts
- •Musst Holdings Limited (Musst) claimed Astra Asset Management UK Limited and Astra Asset Management LLP (Astra) owed them a share of investment management fees based on a novated contract.
- •The original contract (Octave Contract) was between Musst and two Octave entities.
- •Astra argued the contract wasn't novated, or that any liability ended when investment strategies changed (by 31 December 2014 or 31 December 2015) or a fund was restructured (31 December 2015).
- •The disputed amount was approximately US$3.8m (or US$2.3m if Astra's claim on the fund restructuring succeeded).
Legal Principles
Novation requires consent of all parties, which can be express or implied from conduct. It must provide business efficacy to what happened.

Estoppel by convention requires a common assumption shared by the parties, reliance by one party, and unconscionability if the assumption is denied.

Outcomes
Appeal dismissed on all grounds.
The judge's findings on novation (both contractual and by estoppel) were supported by the evidence and context. The judge correctly interpreted the Octave Contract; Astra's liability was not contingent upon the continued adherence to the original investment strategy or the lack of restructuring of ASSCFL.
