Houghton & Anor v Arms

Houghton and another (appellants) appealed to the High Court of Australia against a decision of the New South Wales Court of Appeal, which had affirmed a judgment in favour of Arms (respondent). The dispute concerned the enforceability of a written agreement for the sale of shares in a company, where the purchasers (appellants) alleged that the agreement was void for uncertainty and/or was not binding due to a failure to satisfy a condition precedent.

The High Court was required to determine whether the agreement for the sale of shares was sufficiently certain to be enforceable, and if not, whether it was rendered binding by the conduct of the parties. Specifically, the court considered whether the terms relating to the "terms and conditions" of the sale were so vague as to render the agreement void, and whether the parties' subsequent actions indicated an intention to be bound despite any initial uncertainty.

The High Court held that the agreement was not void for uncertainty. The court reasoned that the phrase "terms and conditions" in the context of a share sale agreement, while broad, did not render the essential obligations of the parties unascertainable. Furthermore, the court found that the parties' conduct, including the execution of the agreement and subsequent steps taken towards completion, demonstrated a clear intention to be bound by the contract, thereby overcoming any arguable lack of certainty. The principles of contractual interpretation, focusing on the objective intention of the parties, were central to this reasoning.

The appeal was dismissed.
