A bid by Nathans Finance's former auditor could derail a $66 million claim brought by the failed firm's receiver.
Nathans Finance collapsed in August 2007, owing 7000 investors about $174 million.
Its former directors - Mervyn Doolan, John Hotchin, Kenneth (Roger) Moses and Donald Young - were convicted this year on Securities Act charges relating to untrue statements made in the company's offer documents.
Moses and Doolan were sentenced to more than two years' jail while Young got nine months' home detention. Hotchin, who made an early guilty plea and then testified against his former colleagues, received 11 months' home detention.
PricewaterhouseCoopers receiver Colin McCloy is attempting to recover investor losses from the directors and the firm's auditor, Staples Rodway.
