Salomon Smith Barney Australia Corporate Finance Pty Ltd v Allgas Energy Ltd

Salomon Smith Barney Australia Corporate Finance Pty Ltd sued Allgas Energy Ltd for the recovery of a fee for their role as lead manager in the sale of Allgas' securities. The dispute hinged on whether the defendant was obligated to pay the fee under the terms of their written agreement, and if not, whether the circumstances warranted the implication of a term. The case was heard by the Federal Court of Australia.

The court had to decide whether an implied term regarding the defendant's payment obligations existed, and if so, whether it was necessary to give business efficacy to the contract. The court also considered whether the nature of the transaction changed post-contract, which could lead to the implication of a new term. Furthermore, the court examined the admissibility of post-contractual conduct and statements in determining whether a term should be implied.

The court held that the written agreement did not explicitly obligate the defendant to pay the fee. However, the court found that the nature of the transaction had changed post-contract, and the circumstances warranted the implication of a term. The court ruled that the subsequent conduct and statements of the parties could be used to imply a term, but in this instance, they did not support the plaintiff's claim. The court determined that the defendant was not obligated to pay the fee under an implied term. Consequently, the court dismissed the plaintiff's claim and entered judgment in favour of the defendant.
