The 19-year-old, the product of Mr Wright's relationship with Elizabeth Anne Mead after he divorced three earlier wives, was originally due to receive $3 million in a trust fund triggered by her 30th birthday.

Mr Sanderson notes in the dossier that Ms Mead would have been deemed exempt from the funds if she "had any association or involvemnet whatsoever to illegal drugs" was convicted of any felony within the 10 years prior to his death, of if she had "converted to Buddhism or Islam". In fact the judgment notes that not only did the fund fail to "make adequate provision" for Ms Mead but that the many clauses within the trust meant there was "a real propsect she might get nothing".

It goes on to detail that a drink driving offence or possession of marijuana would exclude her from the money and noted that giving up her freedom of religion was "an extraordinary proposition" which contravened a basic human right. Contrasting with the "poor little rich girl" headlines the case has spawned, Mr Sanderson also noted Ms Mead was "in no sense ... spoilt by her father". "During her childhood the deceased provided little to the plaintiff or her mother in material support," he said. "He did pay childcare as he was obliged to do under the relevant legislation. "He paid for school fees for a private college and he provided the plaintiff with some pocket money. But really that was the extent of his largesse.

"Any gifts he gave the plaintiff were of nominal value. "The deceased never purchased a home in which the plaintiff and her mother could live despite the fact they moved a number of times from one rented premises to another." Mr Sanderson said Ms Mead did not impress him as "a gold digger or in some way a narcissistic greedy individual" - despite some of the extraordinary items she was asked by lawyers and actuaries to list for her claim, specifying her likely expenditure for the rest of her life. Despite having, now infamously, drafted a wishlist that included a $2.5 million house, a $1.5 million piano, an allocation of $40,000 a year for holidays and five pairs of $50,000 shoes a year for life, Mr Sanderson added "that was a big task for a 19-year-old girl." Having a keen interest in music, she had also called for a diamond-encrusted Ritter Royal Flora Aurum bass guitar worth $250,000, which features a nut carved from 10,000-year-old mammoth ivory and a fingerboard decorated with a floral inlay pattern in 24-carat gold.

Each leaf is decorated with a black diamond set in platinum. "No one needs a guitar of that value - particularly a 19-year-old girl who is not now and never will be a professional musician and who has not had guitar lessons for some years," Mr Sanderson said. "Faced with a question about what guitar she might like she let her imagination run wild. "A 19-year-old boy in the same position would probably, when asked about a car, have nominated a Ferrari or a Lamborghini." With AAP
