BINGHAM & BINGHAM

The parties to this proceeding were the applicants, Mr and Mrs Bingham, and the respondent, Bingham & Bingham. The dispute concerned the interpretation and enforceability of a deed of settlement entered into between the parties. The matter came before Sexton J of the Supreme Court of Victoria.

The central legal issue before the court was whether the deed of settlement, which purported to resolve a prior dispute between the parties, was valid and enforceable, or whether it was vitiated by a fundamental mistake. Specifically, the court had to determine if the parties had entered into the deed under a shared, fundamental misunderstanding of a crucial fact that went to the root of the agreement.

Sexton J considered the principles of contract law relating to mistake. His Honour noted that for a contract to be voidable due to common mistake, the mistake must be fundamental, meaning it must render the subject matter of the contract essentially different from what the parties believed it to be. The court examined the evidence surrounding the negotiations and execution of the deed, paying close attention to the knowledge and assumptions of each party at the time. His Honour found that the alleged mistake was not sufficiently fundamental to vitiate the deed, and that the parties had intended to compromise the existing dispute on the terms set out in the deed, regardless of the precise factual circumstances that were later brought to light.

The court therefore held that the deed of settlement was valid and enforceable. The applicants' claim was dismissed.
