Jacobsen & Anor v Rogers

The case of *Jacobsen & Anor v Rogers* was heard in the High Court of Australia. The proceedings involved a dispute concerning the seizure of documents by law enforcement officers under section 10 of the *Crimes Act*. The applicants, Mr. Jacobsen and another, were seeking to challenge the legality or scope of such seizures, particularly in relation to sensitive State documents.

The central legal issue before the Court was whether a doctrine of public interest immunity, or its historical equivalent, State privilege, operated to prevent the seizure of documents by law enforcement officers under a warrant. This question arose in the context of arguments about the historical understanding of such privileges in 1914 when the *Crimes Act* was enacted, and whether contemporary legal standards offered sufficient protection to sensitive government information. The Court also considered the extent to which legislative provisions, such as those in the *Australian Federal Police Act* and the *Income Tax Assessment Act*, constrained the actions of officers who seized such documents.

The applicants argued that while a rigorous doctrine of State privilege existed in 1914, it might not have prevented seizure, even if it would have prevented production in court. They contended that modern interpretations of privilege, as seen in cases like *Conway v Rimmer* and applied in Australia, alongside specific legislative duties imposed on officers, provided adequate protection. The Court noted that the *Australian Federal Police Act* does not apply to State police, who may obtain warrants under section 10. However, it was suggested that State police officers executing such warrants might be subject to secrecy obligations under the *Income Tax Assessment Act*, potentially deeming them officers for the purposes of that Act and thus bound by its confidentiality provisions.
