The final determination on a tax bill from more than 10 years ago could be delayed once more as a notorious family fights to put off their own appeal. The family of corrupt former Labor powerbroker Eddie Obeid is still locked in a court battle with the tax office over a $30 million windfall from the sale of a coal project. Eleven members of the family or their spouses, including Eddie's wife Judith and son Edward Jr, simultaneously appealed a 2014 tax office decision that they owed tax on the money earned from the sale of the family farm to a coal company. That lawyer is Eddie's longtime criminal solicitor, Michael Bowe, who admitted in the Federal Court on Tuesday to being out of his depth. The tax office ordered the payment of income tax plus penalties on at least $30 million that was paid to the Obeids as part of a coal deal involving their farm.
