Rebel Wilson And Defamation Risk: When Public Allegations Move From Belief To Proof

When serious allegations are published – intentionally, publicly and to a mass audience – the legal question is immediate and unforgiving: who must justify them? Under Australian defamation law, the answer is not the person defamed. It is the person who chose to publish.

Rebel Wilson has made public allegations on social media. Once serious allegations are made openly and to a wide audience, they cease to be mere statements. They become publications carrying immediate legal consequences – fixed, examinable and capable of outliving the moment in which they were made.

Under Australian defamation law, the onus does not fall on the person defamed to disprove what has been said: it falls on the publisher to justify it. That principle is now being tested before the Federal Court of Australia in MacInnes v Wilson in which actress Charlotte MacInnes is suing actress and director Rebel Wilson for defamation.
