Bankrupt businessman Seán Quinn will argue today that he should be allowed personally defend a claim that he is liable for loans of over €2bn.
The loans were extended to various Quinn companies by Anglo Irish Bank.
Mr Quinn believes he is entitled to personally defend the claim against him by the now-renamed Irish Bank Resolution Corporation (IBRC) even though he is bankrupt.
The official assignee in the bankruptcy has decided not to represent him in an action by the Quinn family against the bank.
IBRC lawyers say Mr Quinn is not entitled to represent himself in those proceedings, but the businessman is challenging that and has hired solicitors to put his side before the Commercial Court today.
