Members of businessman Sean Quinn's family want the former Chief Executive of Anglo Irish Bank, David Drumm, to give evidence in their action against the bank.
Patricia Quinn and Mr Quinn's children deny liability for loans of more than €2 billion given by Anglo to Quinn companies.
They claim the loans were illegal as they were given for the purpose of propping up the bank's share price.
Mr Drumm is currently serving a six year jail sentence for directing a conspiracy to dress up Anglo's accounts by €7.2 billion in 2008, and for presenting the false figures to the market.
The family's action against the former Anglo Irish Bank is now due to get underway in the Commercial court next March.
The issue of whether or not Mr Drumm will give evidence will be addressed next month in a pretrial hearing.
A separate action by the bank against various Quinn family members and others, alleging they put multi-million assets beyond the bank's reach, will be heard afterwards.
Both sets of proceedings were on hold until criminal proceedings concerning Anglo Irish Bank had been completed.
