Patrick v The State of South Australia

This case concerned an appeal to the Supreme Court of South Australia regarding an application made under the Freedom of Information Act 1991 (SA) for access to documents related to the Northern Water Supply Project. The applicant sought various ministerial briefings and correspondence concerning a desalination plant for Port Lincoln, as well as substantive reports generated by Infrastructure SA. The Department of Premier and Cabinet identified 18 documents responsive to the request, but claimed some were exempt from disclosure.

The primary legal issues before the Court were the proper construction of clause 1(1)(e) of Schedule 1 of the Freedom of Information Act 1991 (SA), which exempts documents "concerning any deliberation or decision of Cabinet," and the application of this clause, along with clause 1(1)(a), to the specific documents in contention. The Court was required to determine the scope of the exemption and whether the documents, or information within them, qualified as being "concerning any deliberation or decision of Cabinet."

The Court applied established principles of statutory construction, emphasising that interpretation must begin and end with the statutory text, considered in its context. It found that the word "concerning" in clause 1(1)(e) extended the exemption beyond documents that directly disclosed Cabinet deliberations or decisions. Information that informed Cabinet deliberations was capable of being covered by the exemption, provided it could be identified as the subject matter of those deliberations. This identification could be made from the face of the document or from publicly available extrinsic information. The Court also considered the Infrastructure SA Assurance Framework as relevant context for characterising the documents.

The Court concluded that while the choice of the word "concerning" broadened the exemption, the mere submission of a document to Cabinet was insufficient to render its contents exempt. The information had to be identifiable as the subject matter of Cabinet deliberations. The Court then proceeded to apply this construction to the remaining documents in contention.
