Komatsu Marketing Support Australia Pty Ltd v Marsh Pty Ltd

In the case of Komatsu Marketing Support Australia Pty Ltd v Marsh Pty Ltd, the dispute between the parties involved issues concerning the admissibility of certain documents during the discovery process, and the application of legal privilege. The case was heard in the Supreme Court of Western Australia. The primary legal issue the court had to decide was whether documents subject to 'without prejudice' privilege were discoverable, and if section 131(2)(g) of the Evidence Act 2005 applied in the context of discovery.

The court considered the argument presented by Komatsu that the Associate Judge erred in finding that section 131(2)(g) of the Evidence Act applied to discovery. The court noted that while the issue was not argued extensively before it, it did not find any fundamental reason why the section could not apply to discovery. The court reasoned that there could be circumstances, such as when issues emerge during the course of a trial in which evidence has already been adduced, where a party may be required to provide further discovery. As a result, the court dismissed Marsh's appeal from the decision of Harrison AsJ, with costs.

In the context of Komatsu's claim against Marsh, the court found that Komatsu's assertion that its contribution to a settlement was reasonable was not an essential element of its cause of action. Komatsu was still required to prove that it suffered loss and damage and the quantum of that loss, regardless of its assertions concerning the reasonableness of any sum it contributed to the settlement. The court also noted that any legal advice Komatsu may have received concerning the issues in question was irrelevant to the pleaded case against Marsh, as it did not seek to justify or support any particular course of action taken in the Western Australian proceedings.

The final orders of the court were that Marsh's appeal from the decision of Harrison AsJ was dismissed, with costs.
