David Drumm has lodged an appeal against last week's decision to deny him bail ahead of his extradition hearing in the US.
The former Chief Executive of Anglo Irish Bank, has already been refused bail twice and remains in custody in Boston.
Drumm faces 33 criminal charges relating to transactions carried out while he was in charge of the bank.
The Dubliner is currently being held in a maximum security prison, he faces an extradition hearing in March.
He was refused release before the pending extradition hearing as the judge ruled that he has "an incentive to flee," given the serious nature of the charges that Mr Drumm faces in Ireland
In November, he made a personal appeal to a Massachusetts Court to be released and held under house arrest until his hearing.
