Civil Aviation Authority v Australian Broadcasting Corporation [No 1]

The Civil Aviation Authority (CAA) sought to restrain the Australian Broadcasting Corporation (ABC) from publishing certain information relating to the CAA's internal operations. The dispute concerned the ABC's intention to broadcast a report based on confidential documents obtained by a journalist, which allegedly revealed deficiencies in the CAA's safety procedures and management. The matter came before the New South Wales Court of Appeal.

The primary legal issue before the Court of Appeal was whether the CAA was entitled to an interlocutory injunction to prevent the publication of the information. This involved determining whether the CAA had established a sufficient likelihood of success in ultimately proving that the ABC's proposed publication would breach a duty of confidence owed to the CAA, or whether other legal grounds, such as defamation, were relevant and could be established. The Court also considered the public interest implications of both publication and restraint.

The Court of Appeal ultimately dismissed the CAA's application for an interlocutory injunction. It reasoned that the CAA had failed to demonstrate a strong prima facie case that the information was imparted in circumstances importing an obligation of confidence, or that such an obligation, if it existed, had been breached. Furthermore, the Court found that the ABC had raised a defence of publication in the public interest, which, if established, would defeat any claim of breach of confidence. The Court also noted that the information concerned matters of public safety and administration, which weighed against granting an injunction that would stifle public scrutiny.
