McKinnon v Secretary, Department of Treasury

McKinnon initiated legal proceedings against the Secretary of the Department of Treasury in an Australian court. The dispute revolves around the interpretation and application of the Freedom of Information Act, specifically concerning the release of certain documents and the classification of reports from scientific and technical experts. The case was heard and determined in the Federal Court of Australia.

The court was tasked with deciding several key legal issues. First, whether the Tribunal's error in viewing a communication with a member of the Minister’s private staff as a communication with the Minister contributed to the final decision. Second, whether section 36(6)(a) of the FOI Act extends to reports from econometricians, actuaries, and statisticians. The court had to assess if the error made by the Tribunal influenced the outcome and if the definition of "scientific or technical" reports should include those from econometricians, actuaries, and statisticians.

The court reasoned that even if the Tribunal erred in its interpretation, there was no evidence to suggest that this error influenced the final decision. Regarding the second issue, the court found no error in the Tribunal’s interpretation of the FOI Act, aligning with the decision in Harris v Australian Broadcasting Corporation. The Tribunal’s understanding of "scientific or technical" was deemed to accord with the natural meaning, and thus, the court upheld the Tribunal's reasoning.

The court dismissed the appeal, holding that the Tribunal did not err in its interpretation and application of the FOI Act. Consequently, the appellant was ordered to pay the respondent's costs.
