"In particular, this court has rejected the finding that Rebel Wilson lost the opportunity to earn AU$15m by being cast in lead or co-lead roles in three Hollywood feature films during the period from mid-2015 to the end of 2016", Justice Pamela Tate said.
The articles alleged Wilson had lied about her age, her name and her upbringing in Australia, and were featured across Australian magazines, including Bauer's Australian Women's Weekly, New Weekly and OK Magazine.
The star of three "Pitch Perfect" movies and "Bridesmaids" won AUS$4.6 million (US$3.5 million) in damages from the German publisher previous year after a court found a series of articles accusing her of lying about her age, name and childhood events had cost her roles.
She claimed that the articles had prevented her from furthering her Hollywood career, alleging she'd been sacked from two projects, "Trolls" and "Kung Fu Panda 3", due to eight different articles, and was awarded A$4.5 million (£2.7 million) in damages, the largest payout for defamation in Australian history.
An appeals court has slashed Rebel Wilson's record 4.6 million Australian dollar (£2.5 million) damage award to 600,000 Australian dollars (£338,000) after a magazine publisher appealed the amount of its payout in a defamation case.More news: Uber will learn to calculate the drunken passengers

But the Court of Appeal found there was no basis for her to be awarded financial damages for the potential loss of roles, setting aside the economic damages entirely.
As I've said before, I have already WON the case and this is UNCHALLENGED!' she wrote.
Taking to Twitter before the judgement was delivered, Wilson said the appeal was about Bauer Media "quibbling about how much they now have to pay me". And that while it's not about the money, she'd like to cop as much as possible so she can donate it all to charity and the Aussie film industry.
Bauer did not, however, appeal the verdict that the articles were defamatory, but argued the Australian-record damages awarded in September were excessive.
Wilson is overseas at the moment, so she has yet to comment on today's decision.
