Lowe v Lang

The case of Lowe v Lang was heard in the Supreme Court of New South Wales. The dispute centred around whether certain documents that were subject to legal professional privilege should be disclosed. The plaintiff, Lowe, sought to adduce privileged documents in evidence, while the defendant, Lang, contested the admissibility of these documents. The central issue for the court was to determine whether the privilege had been waived and, if not, the extent of disclosure required when a party seeks to use privileged material in their case.

The legal issues before the court involved the application and scope of legal professional privilege, particularly under the Evidence Act 1995 (NSW), and whether any waiver of this privilege had occurred. The court had to consider the principles governing the waiver of privilege and whether the plaintiff had effectively waived the privilege by disclosing the documents to third parties. Additionally, the court examined whether the disclosure of these documents was necessary and proportionate to the issues at hand.

The court found that the plaintiff had not waived the privilege attaching to the documents. It held that there was no evidence to suggest that the plaintiff had intentionally or negligently disclosed the privileged information to any unauthorised person. The court emphasised that a party must deliberately and unequivocally waive the privilege for it to be lost. Given this finding, the court held that the documents were protected by legal professional privilege and could not be disclosed. Consequently, the court ruled that the plaintiff was not entitled to use the privileged documents as evidence in the case.

The final orders of the court were that the privileged documents were inadmissible as evidence in the proceedings. The court also noted that the plaintiff's attempt to rely on these documents had potentially prejudiced the defendant's right to a fair trial. The decision underscored the importance of maintaining legal professional privilege and the stringent requirements for its waiver.
