LMI Australasia Pty Ltd v Baulderstone Hornibrook Pty Ltd

LMI Australasia Pty Ltd (LMI) appealed to the New South Wales Court of Appeal against a decision of the Supreme Court of New South Wales concerning a dispute with Baulderstone Hornibrook Pty Ltd (BH). The core of the dispute involved the interpretation of a contract and the assessment of damages arising from alleged breaches.

The Court of Appeal was required to determine several key legal issues. These included the meaning of "successful" in the context of contractual conditions, the principles governing the construction of commercial contracts, and the admissibility of pre-contractual and post-contractual material as evidence to aid in contractual interpretation. The court also considered the significance of the substitution of contracting parties, the application of the "surrounding circumstances" rule and the dictionary principle in contract construction, and the doctrine of frustration. Furthermore, the court had to assess whether the actions of common directors constituted inducing a breach of contract and how to resolve gross uncertainty regarding damages.

In its reasoning, the Court of Appeal applied established principles of contractual interpretation, emphasising the importance of the plain meaning of the words used in the contract, read in their context. The court considered the admissibility of extrinsic evidence, noting that such evidence is generally not admissible to contradict or vary the plain meaning of a contract unless there is ambiguity. The court found that the mere failure of common directors to prevent a breach of contract did not amount to inducing a breach, distinguishing this from a conspiracy. Regarding damages, the court held that where gross uncertainty exists due to a lack of evidence, such uncertainty should be resolved against the party who bore the onus of providing that evidence.

The appeal was dismissed, and the decision of the Supreme Court was upheld. The court ordered that LMI pay BH's costs of the appeal. The cross-appeal concerning costs was also dismissed.
