Gubbay v Burnet

The appeal concerned a dispute between Gubbay (appellant) and Burnet (respondent) regarding the termination of a contract. The primary legal issues before the Court of Appeal of New South Wales were whether the respondent was estopped from terminating the contract due to the appellant's breach, whether the contract had been affirmed, and whether a release of the cause of action had occurred by way of accord and satisfaction.

The court considered whether the respondent's conduct gave rise to a promissory estoppel, preventing them from exercising their contractual right to terminate. It also examined whether the appellant's actions constituted an affirmation of the contract after the breach, thereby precluding termination. Furthermore, the court assessed whether any agreement reached between the parties amounted to an accord and satisfaction, which would extinguish the original cause of action for breach.

The Court of Appeal ultimately dismissed the appeal. The reasoning involved a detailed analysis of the principles of estoppel, affirmation, and accord and satisfaction in the context of contractual disputes. The court found that the elements required for these defences were not established on the facts, and therefore the respondent was entitled to terminate the contract. The appeal was dismissed with costs.
