Colakovski v The Australian Telecommunications Commission

The applicant, the Telecommunications Commission, sought special leave to appeal from a decision of the Full Court of the Federal Court. The dispute concerned whether the identity of a subscriber to the telecommunications system who made nuisance calls to another subscriber was protected as a personal affair under section 41(1) of the *Freedom of Information Act 1982* (Cth).

The primary legal issue before the High Court was whether the identity of the subscriber from whom nuisance calls originated constituted information relating to the personal affairs of that individual, thereby exempting it from disclosure under the *Freedom of Information Act*. The applicant contended that the name and telephone number of the subscriber were not personal affairs but rather public information, and that any inferences that could be drawn from this information did not alter its fundamental character.

The applicant argued that the Full Court of the Federal Court had erred in its reasoning by considering the potential inferences that could be made from the disclosed information, rather than focusing on the nature of the information itself. The applicant submitted that the name and telephone number of the subscriber were not inherently personal affairs, and that the fact that such information, when combined with other details, might reveal reasons for making the calls did not render the subscriber's identity a personal affair. The court was invited to consider the reasoning of Lockhart J in the Full Court, who had acknowledged a "real question" as to whether a name and telephone number could be described as information relating to personal affairs, but ultimately approached the matter on the basis of the specific documents in question.
