Australian Competition and Consumer Commission v Cadbury Schweppes Pty Ltd

In the matter of Australian Competition and Consumer Commission v Cadbury Schweppes Pty Ltd, the Full Court was tasked with determining the extent of legal professional privilege, specifically litigation privilege, in relation to finalised proofs of evidence filed and served on an opponent in existing litigation. The case involved complex issues concerning the confidentiality of documents created for use in litigation and the implications of filing such documents in court.

The primary legal issues before the court were whether the finalised proofs of evidence prepared by the ACCC were subject to litigation privilege and, if so, whether their filing and service constituted a waiver of that privilege. The court had to navigate the conflicting legal principles and authorities concerning the scope of litigation privilege, including its application to documents and the necessity for confidentiality.

The court reasoned that litigation privilege extends to documents created for the dominant purpose of conducting anticipated or pending litigation. However, the court noted that the scope of the confidentiality arising from litigation privilege differs from advice privilege. The court concluded that the filing and service of the finalised proofs of evidence did not constitute an implied waiver of litigation privilege because the documents were served in compliance with a court order and subject to a confidentiality regime. The court emphasised that the principles of common law should govern the issue, as opposed to statutory provisions under the Evidence Act.

The Full Court granted Cadbury leave to withdraw its concession and argue the new matters it sought to raise. The appeal was ultimately dismissed, and the parties were required to file and serve proposed draft orders and submissions regarding the costs of the appeal.
