Sanrus Pty Ltd v Monto Coal 2 Pty Ltd

In the case of Sanrus Pty Ltd v Monto Coal 2 Pty Ltd, the dispute revolves around the interpretation of a joint venture agreement between the plaintiffs, Sanrus Pty Ltd, and the first defendant, Monto Coal 2 Pty Ltd. The agreement included a clause that required the parties to use all reasonable efforts to develop stage 1 of a coal resource project. The plaintiffs alleged that the first defendant decided not to develop stage 1 and failed to act in good faith and reasonably. The first defendant, in turn, argued that their decision was based on the economic viability of the project and that they acted in accordance with the agreement's proper construction. The third defendant, who was not a party to the joint venture agreement, was alleged to have intentionally induced the first defendant to breach the agreement.

The legal issues before the court included whether the defendants had waived the privilege over their legal advice by asserting states of mind inconsistent with the maintenance of privilege, and whether the inadvertent disclosure of a note containing a summary of legal advice amounted to an implied waiver of privilege. The court also had to consider whether the partial redaction of a file note of a meeting between a deceased witness and the defendants’ solicitors amounted to an implied waiver of privilege over the file note in its entirety.

The court determined that the defendants had not waived privilege over their legal advice by asserting states of mind inconsistent with the maintenance of privilege. It was found that the defendants' conduct during the trial did not amount to an implied waiver of privilege. Regarding the inadvertent disclosure of the note containing the summary of legal advice, the court held that the defendants had not impliedly waived privilege over the legal advice. Finally, the court ruled that the partial redaction of the file note did not amount to an implied waiver of privilege over the file note in its entirety.

The court dismissed the plaintiffs' application, granted leave to the defendants to amend their List of Documents to mark the relevant document as partly privileged, and ordered the plaintiffs to deliver up all hard copies, return any computer disk, and delete all electronic copies of the document in their possession. The court also directed that the version of the document on the Online Review Book be replaced with a redacted version and set aside time to hear the parties on costs.
