Kang v Kwan

Kang, a former client, sued Kwan, a former lawyer, for professional negligence. The dispute centred on the admissibility of certain documents and the applicability of legal professional privilege. The High Court of Australia was called upon to decide the case. The primary legal issues the court had to address were whether the privilege had been lost, whether the evidence could still be adduced under sections 122 and 125 of the Evidence Act 1995, and what constituted consent, fraud, and abuse of power for the purposes of these sections. Additionally, the court had to determine the effect of a letter discovered by the producing party after the client was out of jurisdiction, and the capacity to object to the adducing of evidence when the client was out of jurisdiction.

The court found that the privilege was not lost, and evidence could still be adduced under sections 122 and 125 of the Evidence Act 1995. The court clarified that consent for the purposes of section 122(1) requires actual agreement to the disclosure, not just acquiescence or implied consent. Fraud and abuse of power for the purpose of section 125 involve intentional deception or misuse of authority. The court held that the production of documents under a court order does not necessarily mean that the privilege is waived. Furthermore, the court found that the subsequent discovery of a letter by the producing party, which referred to possible privilege when the clients were out of jurisdiction, did not affect the privilege. The court also held that the capacity to object to the adducing of evidence when the client is out of jurisdiction continues, and a lawyer's duty to protect privilege persists. Finally, the court emphasised the importance of resorting to section 133 of the Evidence Act 1995 to examine documents to ensure that privilege is not inadvertently disclosed.

The court's decision highlights the importance of legal professional privilege and the need for lawyers to take all reasonable steps to protect their clients' interests. The court's clarification of the meaning of consent, fraud, and abuse of power will assist lawyers in advising their clients on the admissibility of evidence and the protection of privileged information. Additionally, the court's emphasis on the importance of examining documents under section 133 of the Evidence Act 1995 will help lawyers to avoid inadvertently disclosing privileged information.
