In brief: The High Court unanimously dismissed an appeal from the Full Court of the Federal Court, holding that legal professional privilege is not a legal right capable of enforcement through a cause of action. It is an immunity from the exercise of powers that would otherwise compel disclosure of the material.
The appellants sought an injunction restraining the defendants from using certain documents on the basis that those documents were subject to legal professional privilege. The appellants were companies that formed part of the global Glencore plc group. In November 2017, journalists published the ‘Paradise papers’ which included leaked financial records and other internal documents of some of the world’s largest companies, including the Glencore group. The documents relevant to this case were created for the dominant purposes of the provision by a Bermuda based law practice of legal advice to the plaintiffs. The Australian Taxation Office purported to make use of the documents. That the documents were privileged was not in dispute. The plaintiffs did not seek relief on the ground of confidentiality.
The appellants contended that previous decisions of the Court did not limit the parameters of legal professional privilege only as an immunity. They argued that its scope should be determined by the policy of the law it is based on, namely the administration of justice through fostering trust and candour between lawyers and their clients. They also argued that it is illogical for the privilege to be considered a fundamental right, yet for breach of confidence to be the only available means for enforcement. Other common law jurisdictions have recognised certain general law rights as being capable of supporting an injunction. The Court rejected those arguments. The characterisation of the privilege as an immunity, with the scope it has, is well established: Daniels Corporation International Pty Ltd v Australian Competition and Consumer Commission (2002) 213 CLR 543; Commissioner of Australian Federal Police v Propend Finance Pty Ltd (1997) 188 CLR 501. The Court said at [13]:
It is not sufficient to warrant a new remedy to say that the public interest which supports the privilege is furthered because communications between client and lawyer will be perceived to be even more secure. The development of the law can only proceed from settled principles and be conformable with them. The plaintiffs' case seeks to do more than that. It seeks to transform the nature of the privilege from an immunity into an ill-defined cause of action which may be brought against anyone with respect to documents which may be in the public domain.
The Court also made some remarks about the history and evolution of the privilege and the increasing number of statutory regimes containing compulsive powers concerning information.
