Rebel Wilson's lawyer has implored the jury in the Hollywood actor's defamation case to send a clear message to tabloid magazines and "hold them accountable".
Matthew Collins QC says Wilson's "raw" and "candid" testimony during her defamation trial against Bauer Media is evidence she is "obviously not a serial liar".
Dr Collins praised the Pitch Perfect actor's behaviour and composure during the past three weeks in the Supreme Court of Victoria.
He asked the jury to return a verdict in favour of Wilson to "send a message" to tabloid magazines that it's not okay to run stories without giving people the right to reply, or to pay anonymous sources for dubious information.
"Hold them accountable," Dr Collins told the jury on Friday.
He said Wilson needed the jury's verdict in order to restore her reputation.
"She's not here for money."
During his closing address on Friday, Dr Collins referred to the Bible while discussing the seriousness of being called a liar.
He said not lying was one of the 10 Commandments taught to children, with ordinary and reasonable members of society thinking less of liars.
Wilson, 37, is suing Bauer Media for defamation over a series of articles in May 2015 she says damaged her reputation by painting her as a serial liar and put her out of work for a year and a half.
The articles claimed to reveal the truth about Wilson's "real" name, age and childhood after the actor added a touch of "fantasy" in order to "make it in Hollywood".
The actor, who grew up in Sydney but now lives in California, has maintained throughout the trial she has never lied to journalists.
One of Bauer's defences is that the matters referred to in the article were "trivial" and unlikely to cause the actor any real harm.
Dr Collins referred to a "pre-interview" former Australian Women's Weekly journalist Caroline Overington claims she had with the 37-year-old star before a formal interview in October 2014.
Ms Overington previously gave evidence that Wilson confirmed with her that she was 29, that her real name was Rebel and that she was related to Walt Disney.
However, Dr Collins said that conversation never happened.
He said the inclusion of the star's age in Ms Overington's article did not occur until its 10th draft after an editor checked the IMDB movie database website, which erroneously listed Wilson's age as 29.
The jury is expected to retire to consider its verdict on Tuesday afternoon.
