In its appeal against the decision, Bauer Media argued that the $4.5 million payout was excessive and should be set aside due to errors in fact and law.
Wilson alleged she was defamed in several articles published in 2015, including a Woman's Day story titled 'Just who is the REAL Rebel?'
Which means Wilson's lawyers are heading back to court on Thursday when the decision on that damages appeal is handed down - and they're going without Wilson, because hey, she's in Prague, remember?
A summary of the Court of Appeal's judgement said: "For a considerable number of reasons, the critical inferences drawn by the judge could not be upheld".
An Australian court on Thursday slashed a record libel payout for actress Rebel Wilson, saying there was insufficient evidence a series of magazine articles published by Bauer Media prevented her from getting lucrative roles in Hollywood.
At the time, Wilson tweeted she would be donating the money to Australian charities and supporting the Australian film industry with the money.

A group of North Korean security staff were seen coming back into the hotel with cardboard boxes, one with McDonald's takeaway. Later, they would be joined by their respective negotiating teams for discussions that could last another hour.
Speaking on behalf of Bauer Media, general counsel, Adrian Goss, said: "It was important for us to revisit the award of damages".
"It followed that the judge's award of damages for economic loss had to be set aside, there was no basis in the evidence for making any award of damages for economic loss".
Apparently some weight loss companies are using her image to sell their shit, and Wilson's not into it.
That sum would have been the largest defamation payment ever ordered by an Australian court.
It also reduced Wilson's non-economic losses by 50,000 Australian dollars to 600,000 Australian dollars.
"As I've said before, I have already won the case and this is unchallenged".
The actress she won her defamation case against Bauer Media in September a year ago. Bauer Media immediately said it would appeal the record-breaking payment.
