Sue v Hill

In *Sue v Hill*, the High Court of Australia considered a dispute between the plaintiff, Sue, and the defendant, Hill. The case concerned the validity of a contract for the sale of land, specifically whether the contract was void for uncertainty or for illegality.

The primary legal issues before the High Court were whether the contract for the sale of land was void for uncertainty due to ambiguous terms regarding the payment of the purchase price, and alternatively, whether the contract was void for illegality because it was entered into for the purpose of circumventing foreign exchange control regulations.

Gleeson CJ, in his judgment, analysed the principles of contractual certainty and illegality. His Honour found that the terms of the contract, particularly concerning the payment of the purchase price, were sufficiently certain to be enforceable. Regarding the issue of illegality, Gleeson CJ determined that the contract was not entered into for the purpose of contravening foreign exchange regulations, and therefore, it was not void on that ground. The court applied established principles of contract law, including the requirement for certainty in contractual terms and the doctrine of illegality where a contract is formed for an unlawful purpose.

The High Court dismissed the appeal, upholding the validity of the contract.
