Gina Rinehart tells court she no longer wises to be trustee of family trust Gina Rinehart has walked away from the court feud with her two children. GINA Rinehart has walked away from the court feud with her two children, telling the court on the eve of the hearing that "she no longer wishes to be trustee." It comes a week before the case was due for a showdown in the Supreme Court. John Hancock and his sister Bianca were the remaining two children suing their mother, Australia's richest person, to get control of the family trust. Gina Rinehart and daughter Bianca have been embroiled in a bitter feud over a family trust. Lawyers for Mrs Rinehart have told the Supreme Court: "she has advised the beneficiaries that she wishes to be discharged from her duties as trustee." The mining magnate wants to go to mediation to appoint a new trustee, with the court told she wants someone "who is a lineal descendant," with knowledge of the resources industry and no history" of wanting personal favours. John Hancock was suing his mother Gina Rhinehart over control of a family trust. Her counsel told the court Rinehart had helped the trust "grown enormously through her endeavours and hard work." The long running family feud began in September 2011, after Mrs Rinehart changed the vesting date of the Hope Margaret Hancock Trust until 2068. It had been due to vest in September 2011 when Ginia Rinehart turned 25. Ginia sided with her mother from an early part of the dispute, while daughter Hope pulled out this year due to financial trouble. Ginia Rinehart was the only child to side with her mother over the issue. The trust contains almost 25 per cent of the flagship family company Hancock Prospecting, and was tipped to make each of the four children billionaires. Mrs Rinehart had told the children the Trust couldn't vest at that time because capital gains tax liability would bankrupt them, the court heard. But court documents say tax advice John Hancock received from the Australian Taxation Office contradicted that bankruptcy claim.
