An Australian court ruled Wednesday that actress Rebel Wilson did not defame actress Charlotte MacInnes, dismissing the legal claim in its entirety [1, 2].

The ruling establishes a significant precedent regarding the threshold for reputational harm in social-media-based defamation cases within the Australian legal system [3, 4].

Justice Elizabeth Raper of the Federal Court of Australia in Sydney presided over the case [2, 3]. The court found that MacInnes failed to prove that the disputed social-media posts caused serious reputational harm [3, 2]. Furthermore, the court determined that the single meaning MacInnes was able to prove regarding the posts was actually true [3, 2].

Because the claim was dismissed, the court ordered MacInnes to pay Wilson's legal costs [1, 2]. The decision follows a legal battle over posts made by Wilson that MacInnes argued were damaging to her professional standing [4].

"The plaintiff failed to establish that the statements caused serious reputational harm," Raper said [3].

The ruling emphasizes the difficulty of proving defamation when the statements in question do not meet the legal standard of causing substantial damage to a person's reputation [3, 4].

This ruling reinforces the 'serious harm' threshold in Australian defamation law, suggesting that public figures must provide concrete evidence of reputational damage rather than merely proving a statement was offensive or inaccurate. By ordering the plaintiff to pay the defendant's legal costs, the court further discourages the filing of defamation suits that lack a strong evidentiary basis for harm.
