The Corporations and Markets Advisory Committee (CAMAC) has recommended the law be retained in relation to a High Court of Australia ruling in January 2007 that deemed a Sons of Gwalia shareholder, Luka Margaretic, be entitled to rank equally with all other unsecured creditors of the failed company. The court ruling overturned traditional arrangements with failed companies where shareholders had been ranked lower than secured creditors for damages. Sons of Gwalia was one of Australia's largest gold miners and the world's biggest tantalum producer in the 1980s but collapsed in August 2004 owing more than $700 million after falling short of its gold hedge book commitments.
