A syndicate of 20 banks will have to pay $1.58 billion to the liquidators of Bell Group, Judge Neville Owen of the West Australian Supreme Court ruled yesterday.Owen had left out of his October 2008 judgement - following a three-year trial and a two-year task writing it up - what the actual compensation payable by the banks would be.After wrangling between the liquidator and the banks and a three-day hearing in late March, Owen has now worked this out. In short, the banks have to pay to the liquidators the money received from selling the Bell assets in 1992 plus interest - in other words, an even more comprehensive defeat for the banks in the case than Owen's first judgement implied.The bank may claw some of the money back from the liquidators as they are unsecured creditors of Bell.
