Attorney General for New South Wales v TCN Channel Nine Pty Limited

The Attorney-General for New South Wales, as the applicant, brought proceedings against TCN Channel Nine Pty Limited, the respondent, concerning the broadcast of a television program. The dispute arose from the respondent's intention to broadcast a program that the applicant alleged would breach confidentiality obligations owed to the State of New South Wales. The matter was heard by the Court of Appeal of New South Wales.

The central legal issue before the Court of Appeal was whether the respondent, TCN Channel Nine Pty Limited, could be restrained by injunction from broadcasting the program. This involved determining whether the applicant had established a sufficient legal basis to justify the imposition of such an injunction, particularly in light of the public interest in freedom of expression and the media's role in disseminating information.

The Court of Appeal considered the principles governing the grant of interlocutory injunctions, including the need to establish a strong prima facie case or a serious question to be tried, and the balance of convenience. The Court examined the nature of the alleged breach of confidence, the potential harm to the State of New South Wales, and the public interest in the broadcast. Ultimately, the Court found that the applicant had not demonstrated a sufficient likelihood of success on the merits to warrant the grant of an injunction, and that the balance of convenience favoured allowing the broadcast to proceed, subject to any potential consequences that might arise thereafter.
