State of New South Wales v BT Australasia Pty Ltd

The matter before the court involved the State of New South Wales and BT Australasia Pty Ltd, with the dispute centering on the applicability of client legal privilege to certain confidential communications. The case was heard in the Supreme Court of New South Wales. The state sought to adduce certain documents from BT that were protected by legal privilege, arguing that BT had impliedly consented to the loss of privilege by disclosing the documents to a third party.

The primary legal issue was whether the respondent's actions in disclosing privileged documents to a third party constituted an implied consent to the loss of privilege. The court had to determine whether such an implied consent could exist and, if so, the circumstances in which it would be recognised. This involved an analysis of the relevant provisions of the Evidence Act 1995 (Cth) and the established principles of client legal privilege.

The court found that an implied consent to the loss of privilege could indeed be established, but it required clear and unequivocal conduct by the client that demonstrated such consent. In this case, the court concluded that BT had not acted in a manner that could be construed as an implied consent to the loss of privilege. The disclosure to the third party was not of a kind that would lead a reasonable person to infer that BT intended to waive the privilege. Consequently, the court held that the documents in question remained protected by client legal privilege. The appeal was dismissed, and costs were awarded to BT Australasia Pty Ltd.
