TEC Hedland Pty Ltd v The Pilbara Infrastructure Pty Ltd

TEC Hedland Pty Ltd, the plaintiff, filed an action against The Pilbara Infrastructure Pty Ltd, the defendant, over a dispute concerning the discovery of documents. The plaintiff sought an order to inspect certain documents held by the defendant, asserting that they were relevant to the proceeding. The defendant opposed this application, claiming that some of the documents were protected by legal professional privilege. The case was heard by the Supreme Court of Western Australia. The court had to determine whether the plaintiff was entitled to inspect the contested documents and whether the defendant had waived the legal professional privilege over those documents.

The court examined the nature of multi-addressee emails and their implications for legal professional privilege. It considered whether the disclosure of legal advice in such emails constituted a waiver of privilege. The court also assessed whether the defendant's actions, including the filing of evidence in the application, implied a waiver of privilege. The court found that while the disclosure of legal advice in multi-addressee emails could potentially lead to a waiver of privilege, the defendant had not contested the state of mind necessary to establish an implied waiver. Therefore, the court ruled that there was no implied waiver of privilege in this case.

The court ordered that the plaintiff could inspect the contested documents, as the defendant had not successfully claimed legal professional privilege over them. The plaintiff's application for broader discovery was dismissed, as the court found that the defendant had not impliedly waived the privilege over the documents in question. This decision highlights the importance of carefully considering the implications of multi-addressee emails and the disclosure of legal advice when asserting legal professional privilege in litigation.
