The Pitch Perfect star directed, co-produced and starred in the musical comedy, which became the subject of multiple legal battles in Australia and the US.
On Friday, Justice Elisabeth Peden awarded Wilson $359,000 plus interest in a brief decision, with a written judgement to follow. The judge awarded the trio of producers, Amanda Ghost, Gregor Cameron and Vince Holden, just $10 in damages and otherwise dismissed their summons.
The producers had alleged Wilson made false and derogatory statements about them online, claiming she caused their company financial and reputational damage in an attempt to devalue her debut film so she could buy it from them. Wilson countered by alleging her co-producers' involvement in the film was marked by a troubling pattern of illicit, egregious behaviours, including theft, bullying and sexual misconduct.
Filmed on a $22 million budget, The Deb made just $335,000 at the local box office and is yet to screen outside Oceania. Wilson's co-producers allege that shortfall could be traced to her false and derogatory statements about them online.
Wilson took to Instagram to welcome the victory with a photo of herself in a graduation gown holding a degree from the University of NSW. "This girl never knew how much she was going to need that law degree!!" she wrote.
"I spoke up because I believed there were serious concerns that needed to be raised on my film The Deb," Wilson said. "Defending myself has come at an enormous personal, emotional, and financial cost. But I'm proud I stood my ground – for myself and for others I was trying to protect."
Wilson said she struggled to remain positive throughout the proceedings and thanked her family and followers for their support.
The victory follows Wilson's earlier success this year when she was cleared of defaming the film's star, Charlotte MacInnes, following a Federal Court hearing. MacInnes had claimed Wilson defamed her in four social media posts that implied she was a liar and a sellout who walked back a sexual harassment complaint to further her career. That decision is under appeal.
MacInnes denied making or retracting a complaint about feeling uncomfortable when co-producer Amanda Ghost asked to have a shower and a bath together. MacInnes insisted she had not been uncomfortable when the pair shared a bath in their swimwear after Ghost suffered a medical episode in September 2023.
