Head Quarters (WA) Pty Ltd (Trustee) v Mubarakai

In the Federal Court of Australia, the case of Head Quarters (WA) Pty Ltd (Trustee) v Mubarakai revolved around a dispute concerning legal professional privilege. The trustee of Head Quarters (WA) Pty Ltd sought to rely on legal professional privilege to exclude certain documents from being admitted as evidence in the proceedings. One of these documents was an email from the applicant to his solicitor, which had inadvertently been included as an annexure to an affidavit. The solicitor had struck through the email, indicating that it was not intended to be part of the affidavit. The court was tasked with determining whether the inadvertent inclusion of the email in the affidavit constituted a waiver of the legal professional privilege.

The central legal issue the court had to resolve was whether the inadvertent disclosure of the email in the affidavit resulted in a waiver of the legal professional privilege that protected the communication between the applicant and his solicitor. The court needed to consider the nature of the inadvertent disclosure, the steps taken by the solicitor to indicate that the email was not intended to be disclosed, and the principles governing the waiver of legal professional privilege.

The court found that the inadvertent disclosure of the email did not result in a waiver of the legal professional privilege. The court noted that the solicitor had clearly indicated the email was not intended to be disclosed by striking it through. This clear indication, coupled with the absence of any other evidence suggesting an intention to waive the privilege, led the court to conclude that the privilege had not been waived. The court emphasised that inadvertent disclosure does not necessarily result in a waiver if there is a clear indication that the disclosure was not intended. Therefore, the email from the applicant to his solicitor was removed from evidence on the basis that legal professional privilege over that document had not been waived.

The court's decision was that the email from the applicant to his solicitor be removed from evidence, as the inadvertent disclosure did not constitute a waiver of the legal professional privilege. This ruling was in line with the principles of legal professional privilege, which are designed to protect confidential communications between a client and their legal advisor. The court's order ensured that the privilege was upheld, reinforcing the importance of maintaining confidentiality in legal communications.
