Gina Rinehart's son fighting for fairness Gina Rinehart's son John Hancock says he is fighting for fairness in his family's multi-billion-dollar trust stoush, regardless of his feelings towards his sister Ginia. Mr Hancock, who is a proposed alternative trustee, said the future administration of the trust would be "completely fair." "No matter (what) my personal views are of Ginia, there is no capacity to exercise any favouritism as the trust is no longer a discretionary trust and I am committed to pay out dividends," Mr Hancock said in a statement on Tuesday. It comes after the Supreme Court in Sydney heard allegations Mr Hancock had made "highly disparaging" remarks about Ginia, his youngest sister who has sided with their mother Gina Rinehart in the bitter family battle. Mr Hancock and his sister, Bianca Rinehart, are seeking to oust their mining magnate mother as trustee, claiming she acted "deceitfully" and with "gross dishonesty" in her dealings with the trust, set up in 1988 by her father, Lang Hancock, with her children as the beneficiaries. The pair was previously supported by their sister Hope Welker, but she withdrew from the case earlier this year. Richard McHugh, SC, representing Ginia Rinehart, on Tuesday sought to subpoena unidentified newspaper journalists for their notebooks in relation to Mr Hancock's comments. "There are things John Hancock has said which are highly disparaging of my client, one of the people for whom he wishes to be appointed trustee," Mr McHugh said, adding it went towards Mr Hancock's suitability as proposed trustee. In a statement released later on Tuesday, Mr Hancock rejected this, saying: "No matter my personal opinion of Ginia or my views of her abilities, it would not and can not affect my role as trustee providing each beneficiary with one quarter of the income each." "Fairness is what I'm fighting for and I'm fighting for Ginia and Hope as well," he said. The civil trial has been set down for October 1, with Gina Rinehart expected to attend. Mr Hancock said he looked forward to being cross-examined on his mother's actions in relation to the trust.
