Defamation lawyers frequently encounter the defence of common law qualified privilege.

This blog post provides an overview of the defence, drawing on the case of Palmer v McGowan (No 5) [2022] FCA 893, and other relevant authorities.

The Starting Point: Toogood v Spyring

The origins of the common law defense of qualified privilege can be traced back to the foundational case of Toogood v Spyring (1834) 1 Cr M & R 181; (1834) 149 ER 1044 (at 1049-1050).

In general, the law assumes that the publication of false and harmful statements is malicious.

However, if an individual makes a statement in good faith while fulfilling a public or private duty, or while managing their affairs in which they have an interest, the circumstances may prevent the assumption of malice and offer a qualified defense.

Reciprocity of Duty and Interest

Reciprocity of duty and interest is the hallmark of the common law defence, as highlighted in Cush v Dillon [2011] HCA 30; (2011) 243 CLR 298 (at 305 [11] per French CJ, Crennan and Kiefel JJ).

To succeed in this defence, a publisher must be under a legal or moral duty to disclose the information, or the disclosure must be necessary in the furtherance or protection of legitimate interests of the publisher.

Reciprocally, the interest of the recipient in having information on the subject matter must be of a tangible nature that it is expedient to protect it for the common convenience and welfare of society.

Applicability of the Defence to Large Audiences

The requirement of reciprocity generally precludes the applicability of the defence to large audiences, such as those reached by mass media publications.

As held in Lange, at common law, a claim of qualified privilege will generally fail where a publication is made to a large audience because the publisher cannot establish that it was using the occasion honestly and without malice for the purpose of publishing the defamatory matter to all of the recipients.

Conditions for a Successful Defence

A successful defence of qualified privilege at common law depends upon satisfaction of three conditions, as stated by Heydon J in Aktas v Westpac Banking Corporation Ltd [2010] HCA 25; (2010) 241 CLR 79 (at 96–97 [55]):

The communication was published on a privileged occasion.
The communication was related to the occasion.
There was no malice in the publication.

Applying these principles, it is often difficult to establish a privileged occasion when the publications are made to a wide audience, such as in the case of Palmer v McGowan.

Key take-aways

In summary, the defence of common law qualified privilege is a complex and nuanced area of defamation law.
The requirement of reciprocity of duty and interest, as well as the applicability of the defence to large audiences, are key factors to consider when evaluating the prospects of successfully invoking this defence.
