Australia's richest person, billionaire iron ore heiress Gina Rinehart, is being sued by one of her twin daughters in a Sydney court.
The details of Hope Rinehart Welker's lawsuit remain a mystery after the case was mentioned briefly in the NSW Supreme Court today.
Mrs Rinehart has four children. Her only son John and her first daughter Bianca, who has worked in the family business Hancock Prospecting, were from her first marriage, while twins Gina and Hope were from her second marriage.
Justice Paul Brereton stood the matter over to the same court on September 21 and adjourned to the registrar's list on September 14 a "notice to produce".
Alan Sullivan, QC, barrister for Mrs Rinehart - the only child of the late mining magnate Lang Hancock - told the judge that "in due course, if this case does proceed" he would apply for suppression orders.
But Mr Sullivan asked that, in the interim two weeks until September 21, third-party access - which would include the media - to the court file be restricted.
The judge noted that, to date, there had been a summons, an affidavit and an order of the court.
Mr Sullivan said the application reasons involved "the impact on commercial negotiations".
Justice Brereton agreed to hear argument on Friday afternoon on restricting third-party access.
