Hollywood star Rebel Wilson has thanked the judge and Australian courts for her “substantial win” in a long-running defamation case.

After a blistering dispute that spanned continents and years, a judge on Wednesday ruled that Wilson did not defame her co-star in a series of social media posts.

Australian actor Charlotte MacInnes, who had the lead role in Wilson’s directorial debut film The Deb, had sued the Pitch Perfect star, claiming Wilson’s posts defamed her. MacInnes said they implied she was a liar and a sellout who walked back a sexual harassment complaint to further her career.

The posts alleged the young actor confided in Wilson – and later recanted – that she felt uncomfortable when The Deb‘s co-producer Amanda Ghost asked to have a shower and a bath together.

MacInnes denied making or retracting a complaint, insisting she was not uncomfortable about sharing a bath in her swimwear after Ghost suffered a medical episode in September 2023.

Two months after the conclusion of the hotly contested court fight in the Federal Court, Justice Elizabeth Raper found in favour of Wilson.

“MacInnes has failed to establish that the publications have caused or were likely to cause serious harm,” she said on Wednesday.

Wilson posted her reaction to social media soon after the ruling was made public.

“Thank you to the judge and the Australian legal system for this substantial win today in The Deb matter,” she wrote.

“Look forward to moving on!”

MacInnes’ barrister Sue Chrysanthou SC had accused Wilson of a “complete revision of history” littered with dishonesty during her emphatic closing address in May.

“She is a fantastical liar who has made up terrible, terrible allegations about multiple people and her own witnesses have discredited her,” she said.

“We say Ms Wilson cannot be believed on anything she has said.”

But Wilson repeatedly denied accusations she fabricated the complaint or raised it for leverage during disputes with her co-producers over the film’s budget and writing credit.

“I am known as a truth-teller,” she declared during the hearing.

That was what she had been doing when she posted the stories to her 11 million followers, the Bridesmaids star said.

“I don’t classify it as an attack, I classify it as telling the truth,” she told the court.

Wilson’s barrister Dauid Sibtain SC said she had “no motive to lie” about something that would endanger her film by driving a wedge between her lead actor and a producer.

Instead, he accused MacInnes of dishonestly withdrawing the complaint about Ghost to ensure her relationship with the producer continued to be fruitful.

MacInnes had received a lead role in a stage production and a six-figure record deal that were linked to Ghost, he argued, and she wanted to ensure she continued to rise.

“Ms MacInnes is someone who gave false evidence under oath,” he said.

“[She] has suffered no harm, let alone serious harm.”

MacInnes sought aggravated damages for the harm allegedly wrought by the posts, including anxiety, a period without work.
