Lawyers for a man who used to be second-in-command at Anglo Irish Bank claim he was denied a fair trial and should have his conviction set aside.

Tiarnan O'Â’Mahoney is serving a three year sentence for conspiring to falsify bank records and defraud the Revenue Commissioners.

On foot of a court order in March 2003, Anglo Irish Bank handed over a list of non-resident accounts, which failed to include one linked to a senior figure at the bank.

Last July, Tiarnan OÂ’'Mahoney and former Company Secretary Bernard Daly were convicted of being involved in a conspiracy to defraud Revenue.

Aoife Maguire, who used to work as an Assistant Manager at Anglo, was also jailed but walked free last month following a successful appeal of her sentence. 

During O'’Mahoney’'s appeal today, Brendan Grehan – Senior Counsel for the former Chief of Operations – told the court his client was denied a fair trial.

He claims evidence used during the prosecution of his co-accused had a negative impact on his defence and would not have been allowed if he was tried separately. This included an email from Maguire saying she was working for him directly and the cross-examination of the bank'Â’s Head of Compliance, which Mr Grehan claims was noÂ’t adequately dealt with by the judge.

Bernard DalyÂ’'s appeal is due to begin tomorrow.
