Sprayworx Pty Ltd v Homag Pty Ltd

Sprayworx Pty Ltd sought an order to set aside a notice to produce documents issued by Homag Pty Ltd. The primary issue before the court was whether draft expert reports and communications between the expert and the party retaining them and their solicitors were subject to client legal privilege and thus not required to be produced. Additionally, the court had to determine if the party who sought to rely on the final expert report in the proceedings had waived client legal privilege by doing so.

The court found that the draft expert reports and the communications were protected by client legal privilege. It was held that the party's use of the final expert report in the proceedings did not amount to a waiver of privilege in relation to the drafts and communications. The court reasoned that the final expert report was prepared for a specific purpose, and the drafts and communications were created in the course of preparing that report. The privilege applied to all materials prepared for the dominant purpose of obtaining legal advice or for use in legal proceedings. The court emphasised that privilege would only be waived if the party unequivocally intended to abandon it. The court refused to set aside the notice to produce, holding that the drafts and communications were required to be disclosed as they were not protected by client legal privilege.

The court further held that the party had not waived client legal privilege by relying on the final expert report in the proceedings. The court found that the use of the final expert report did not necessarily mean that the party intended to waive privilege in relation to the drafts and communications. The court determined that the party's use of the final report was not inconsistent with maintaining the privilege over the preparatory materials. The court held that the party could still assert privilege over the drafts and communications unless there was clear evidence of an intention to abandon the privilege. The court's decision was based on the principle that client legal privilege is a qualified privilege, and the party must take positive steps to waive it. The court found that the party had not taken such steps in this case.
