Ascot Investments Pty Ltd v Harper

The High Court of Australia considered an appeal concerning a dispute between Ascot Investments Pty Ltd and the respondents, Mr. and Mrs. Harper. The core of the disagreement involved the validity of a contract for the sale of land, specifically whether the contract was void for uncertainty or for contravention of the *Land Sales Act 1964* (NSW). The primary issue was whether the contract, which contained a clause requiring the vendor to obtain a "satisfactory mortgage" for the purchasers, was sufficiently certain to be enforceable.

The High Court was required to determine two principal legal questions. Firstly, whether the term "satisfactory mortgage" rendered the agreement void for uncertainty, meaning it lacked a definite or ascertainable meaning. Secondly, the Court had to consider whether the contract, if valid, contravened the provisions of the *Land Sales Act 1964* (NSW), which regulated the sale of land by instalment contracts.

The Court, by majority, held that the term "satisfactory mortgage" was not void for uncertainty. It was interpreted as meaning a mortgage that a reasonable person in the position of the purchasers would find acceptable, or one that the purchasers could not unreasonably refuse. The Court reasoned that the law is capable of giving an objective meaning to such terms by reference to what is reasonable. Regarding the *Land Sales Act*, the Court found that the contract did not contravene its provisions, as it was not an instalment contract within the meaning of the Act.

Consequently, the High Court allowed the appeal, finding the contract to be valid and enforceable.
