Cush v Dillon

The High Court of Australia considered a defamation claim brought by the appellant, Cush, against the respondent, Dillon. The dispute arose from the respondent's publication of information concerning the appellant, which the appellant alleged was defamatory. The respondent sought to rely on the defence of qualified privilege.

The central legal issues before the High Court were whether the occasion of publication attracted the defence of qualified privilege, and if so, whether the defence was defeated by express malice. Specifically, the court had to determine whether the respondent's publication of a rumour as "common knowledge" fell within the scope of qualified privilege, and whether the respondent's lack of belief in the truth of the published matter constituted express malice sufficient to rebut the defence.

The High Court reasoned that while an occasion of qualified privilege may exist to communicate the existence of a rumour, the defence does not extend to publishing the rumour as if it were established fact. The distinction between publishing a rumour and publishing the fact that a rumour exists was critical. Furthermore, the court held that a defendant's lack of belief in the truth of a publication is a significant indicator of express malice, capable of rebutting a claim of qualified privilege.

In each of the consolidated matters before it, the High Court dismissed the appeal, upholding the decisions of the lower courts and ordering the appellant to pay the costs of the respondent.
