Alcoa of Australia Ltd and Commissioner of Taxation (Freedom of information)

This matter concerned an application by Alcoa of Australia Ltd for review of a decision by the Commissioner of Taxation to refuse access to documents relating to an Australian Taxation Office audit. The dispute involved the application of various provisions of the *Freedom of Information Act 1982* (Cth) to a request for documents concerning an audit, with the respondent bearing the onus of establishing any claimed exemptions. The case was heard by Deputy Britten-Jones P.

The primary legal issues before the court were whether documents were exempt from disclosure under section 42 of the *Freedom of Information Act 1982* due to legal professional privilege, and if so, whether that privilege had been waived. Further issues included whether documents were exempt under section 38 of the Act, as their disclosure would breach secrecy provisions of the *Taxation Administration Act 1953* (Cth), specifically section 355-25 of Schedule 1, unless an exception under section 355-45 applied. The court also considered claims for exemption under sections 47 and 47F of the *Freedom of Information Act 1982*, relating to trade secrets or commercially valuable information, and the unreasonable disclosure of personal information, respectively, and whether disclosure was contrary to the public interest.

The court's reasoning involved a detailed examination of the statutory framework of the *Freedom of Information Act 1982*, acknowledging the legislative intent to balance public access with competing public interests in non-disclosure. The court considered the specific claims of legal professional privilege and waiver, as well as the application of secrecy provisions within the *Taxation Administration Act 1953* and its exceptions. The court also assessed whether the disclosure of certain documents would reveal trade secrets or diminish their commercial value, and whether access would constitute an unreasonable disclosure of personal information, all within the context of public interest considerations. The decision ultimately varied the initial refusal of access.
