An Australian federal judge ruled Wednesday that actress Rebel Wilson did not defame costar Charlotte MacInnes in a legal battle over social media posts [1].

The decision resolves a high-profile dispute between two performers involved in the film "The Deb," highlighting the legal boundaries of public disputes within the entertainment industry.

Justice Elizabeth Raper of the Federal Court of Australia presided over the case [2]. The court determined that the comments made by Wilson did not meet the legal threshold for defamation [3]. This ruling grants Wilson a complete victory in the lawsuit brought by MacInnes [3].

The legal conflict stemmed from a disagreement involving the production of "The Deb" [4]. MacInnes alleged that Wilson used her as leverage during a separate production dispute, a claim that formed the basis of the defamation suit [4].

The court's decision on July 22, 2026 [1], concludes the litigation regarding these specific social-media interactions. The ruling ensures that Wilson will not be held liable for the damages sought by MacInnes in the proceedings [3].

This ruling underscores the difficulty of proving defamation in cases involving social media disputes between public figures. By determining that the comments were not defamatory, the court has set a precedent for how production-related conflicts and public statements are weighed against legal standards of reputation harm in Australian federal law.
