Ryan v Heiler

In *Ryan v Heiler* [1990] NSWCA 160, the New South Wales Court of Appeal considered a dispute concerning the enforceability of a contract for the sale of land. The appellant, Mr Heiler, sought to enforce a contract against the respondent, Ms Ryan, who had agreed to purchase a property from him. Ms Ryan sought to resile from the agreement, alleging that the contract was void for uncertainty.

The central legal issue before the Court of Appeal was whether the contract for the sale of land was sufficiently certain to be legally binding. Specifically, the court had to determine if the terms of the agreement, particularly concerning the deposit and the date for completion, were so vague or incomplete as to render the contract unenforceable.

The Court of Appeal, applying established principles of contract law, found that the contract was not void for uncertainty. The court reasoned that the terms relating to the deposit, while not specifying an exact amount, were sufficiently ascertainable by reference to the usual practices in conveyancing transactions. Similarly, the absence of a precise completion date did not render the contract void, as the law implies a term that completion should occur within a reasonable time. The court emphasised that it would not readily infer uncertainty where a reasonable interpretation of the terms could give them meaning and effect.

Ultimately, the Court of Appeal dismissed Ms Ryan's appeal, upholding the primary judge's finding that a valid and enforceable contract for the sale of land existed.
