A jury last year found the 36-year-old guilty of sexual assault; he was given a minimum three-year prison sentence.
He has continuously denied that he assaulted the unnamed woman in her bedroom, claiming that they had consensual intercourse.
According to a statement, prosecutors are currently considering whether to drop the accusations against him.
Mr. Hayne played a brief stint as an American football player in the NFL and was one of the most well-known athletes in Australia’s National Rugby League (NRL).
The accused, who is 26 years old, testified in front of the New South Wales (NSW) District Court that Mr. Hayne and she had been corresponding on social media for two weeks prior to her house in Newcastle, which is approximately two hours north of Sydney, being called to a bachelor party in September 2018.
She claimed that even when she told him to stop and “no,” Mr. Hayne still pushed himself on her, leaving her bleeding.
The state’s highest court panel of three justices heard Mr. Hayne’s appeal in April.
Two of the three judges decided on Wednesday that the trial judge erred in forbidding the lady from being cross-examined over specific text messages, which Mr. Hayne’s legal team claimed implied her assent.
