Transfield Pty Ltd v Arlo International Ltd

The High Court of Australia considered an appeal from the Supreme Court of New South Wales concerning a dispute between Transfield Pty Ltd and Arlo International Ltd. The core of the disagreement related to the interpretation and enforceability of a clause within a contract that purported to grant Arlo International Ltd a right of pre-emption over shares in Transfield Pty Ltd. Transfield argued that this clause was void for uncertainty, while Arlo International Ltd contended it was a valid and enforceable contractual provision.

The central legal issue before the High Court was whether the pre-emption clause, which stipulated that Arlo International Ltd had the right to purchase shares in Transfield Pty Ltd at a price to be determined by agreement or, failing that, by valuation, was sufficiently certain to be legally binding. The Court had to determine if the mechanism for determining the share price was adequate to give rise to a concluded contract, or if its inherent uncertainty rendered the entire clause void and unenforceable.

The High Court, by majority, held that the pre-emption clause was void for uncertainty. The Court reasoned that a contract for the sale of shares must specify the price or provide a mechanism for its certain ascertainment. While the clause provided for valuation, the Court found that the mechanism for valuation was not sufficiently defined to ensure a certain price. The absence of a clear, objective, and binding method for determining the price meant that there was no concluded agreement on a fundamental term of the contract, rendering the pre-emption right unenforceable.

Consequently, the High Court allowed the appeal, setting aside the orders of the Supreme Court of New South Wales. The Court declared that the pre-emption clause was void and unenforceable.
