Commonwealth Bank of Australia v Carotino

The appeal before the Full Court of the Supreme Court of South Australia concerned a dispute between the Commonwealth Bank of Australia (CBA) and Carotino (Australia) Pty Ltd. The central issue arose from loan facilities provided by CBA to two fuel companies, Australian Farmers Fuel Pty Ltd and AF Fuels Pty Ltd (the SAFF Companies). These facilities contained a clause requiring CBA's consent to any change in the majority shareholder of the SAFF Companies, failing which the secured monies would become immediately payable. A letter was signed by the parties, wherein CBA consented to a share transfer to Carotino, and Carotino undertook to execute a "Shareholders Guarantee, in a standard form to be provided by the bank within 7 days of receipt." No such formal guarantee was ever executed, and the SAFF Companies subsequently entered voluntary administration. CBA appealed the dismissal of its primary claim that the letter itself constituted an immediately binding contract of guarantee.

The court was required to determine whether the parties intended to enter into an immediately binding contract of guarantee constituted by the letter of 4 May 2007, and if so, whether the terms of such a contract were sufficiently certain. Specifically, the court considered whether the plain wording of the letter, its silence on crucial terms such as whether the guarantee was limited or unlimited, the parties' subsequent conduct, and the availability of a single "standard form" guarantee from CBA, indicated an intention to be immediately bound.

The court upheld the trial judge's finding that the parties did not intend to be immediately bound by a contract of guarantee. This conclusion was based on several factors: the plain wording of the letter, which contemplated the future execution of a formal guarantee; the letter's omission of essential terms, such as whether the guarantee was limited or unlimited, which rendered any purported contract uncertain; the fact that neither party treated the letter as an immediately binding guarantee in their subsequent conduct; and the absence of evidence establishing a single, universally used "standard form" guarantee within CBA at the relevant time. The court applied principles of contract formation, emphasizing that for a binding contract to exist, there must be a clear intention to be immediately bound and sufficiently certain terms.

The appeal was dismissed, affirming the trial judge's decision that no immediately binding contract of guarantee was formed by the letter of 4 May 2007.
