Mining mogul Gina Rinehart settles defamation case against Channel Nine over House of Hancock mini-series

Billionaire mining mogul Gina Rinehart has settled her defamation case against Channel Nine and production company Cordell Jigsaw Zapruder over her portrayal in the 2015 mini-series House of Hancock.

Details of the settlement, which is understood to have been reached following a late night mediation between the parties' legal teams last week, remain confidential, however it is understood that Channel Nine and Cordell Jigsaw Zapruder are both "comfortable" with the outcome.

According to the Gazette of Law and Journalism, Mrs Rinehart's claim "could have led to a significant development in privacy law in Australia".

In March it emerged Mrs Rinehart was planning to argue details such as her weight, whether her father cheated at tennis and the colour of her mother's hair in her claim against Channel Nine and production company Cordell Jigsaw over the broadcast of the hit mini-series.

Mrs Rinehart's lawsuit was based around claims she suffered from injurious falsehood and misleading and deceptive conduct.

The billionaire was seeking damages and a permanent injunction to prevent the program and about four minutes of cuts from being broadcast again.

She also wanted an injunction preventing the DVD copy of the program being advertised as a "true story".

During a hearing in the NSW Supreme Court back in March, Justice Lucy McCallum was told Mrs Rinehart was pursuing her attempt for the suit to become a test case for the establishment of a privacy tort in Australia.

Mrs Rinehart was seeking damages for breach of privacy, claiming she had a right "to live her life without being subject to unwarranted and undesired publicity, including publicity unreasonably placing her in a false light before the public".

In her claim Mrs Rinehart said a scene where her late father Lang Hancock called her a "slothful, vindictive, devious baby elephant" was false.

Further, she claimed the program falsely portrayed her as disloyal to or inconsiderate of her father's needs, including the suggestion she and her father did not often dine together and his wife Rose Lacson Porteous was required to make and bring her dinner at night.

She also denied she chose to get married in a "vulgar and tawdry wedding in Las Vegas" when her mother was dying.
