Plaintiff S246-2019 v Justices of the Federal Court of Australia & Anor

The applicant, identified as Plaintiff S246-2019, sought judicial review of a decision made by the Justices of the Federal Court of Australia, with the Commonwealth of Australia as the second respondent. The core of the dispute concerned the applicant's entitlement to legal professional privilege over certain documents that had been seized by the Australian Federal Police. The applicant contended that these documents were protected by privilege and should not be used in proceedings against them.

The primary legal issue before Gageler J was whether the applicant had established a sufficient basis to claim legal professional privilege over the seized documents, particularly in light of the circumstances of their seizure and the nature of the information they contained. This involved determining the scope and application of legal professional privilege in the context of criminal investigations and the potential for privilege to be abrogated or overridden by statutory powers.

Gageler J's reasoning focused on the fundamental nature of legal professional privilege as a substantive common law right. His Honour affirmed that privilege is not a mere rule of evidence but a right that can only be abrogated by express statutory provision. Applying this principle, Gageler J found that the relevant statutory provisions did not operate to abrogate the applicant's claim to privilege over the seized documents. Consequently, the applicant was entitled to have the privilege claims determined according to the common law. The application was therefore remitted to the Federal Court for determination of the specific privilege claims.
