GORDON & RANIN

The parties to this proceeding were Gordon and Ranin. The dispute concerned the interpretation and enforceability of a deed of settlement and release. The matter came before Watts J of the Supreme Court of Victoria.

The central legal issue before the Court was whether the deed of settlement and release, which purported to extinguish all claims between the parties, was valid and binding, or whether it was vitiated by a fundamental mistake as to the existence of a particular debt. Specifically, the Court had to determine if the parties had proceeded on a common assumption that a debt was owed when, in fact, no such debt existed, and if so, whether this mistake rendered the deed voidable.

Watts J reasoned that for a mistake to vitiate a contract, it must be fundamental and shared by both parties. His Honour considered the principles of common mistake in contract law, noting that such a mistake must render the subject matter of the contract essentially different from what the parties believed it to be. Applying these principles, the Court found that the parties' mutual understanding that a debt was owing was a foundational element of their agreement to settle all claims. As no such debt existed, the basis of the settlement was illusory, leading to the conclusion that the deed was voidable due to common mistake.

The Court ordered that the deed of settlement and release be set aside.
