He has denied all 21 charges.
A former solicitor has gone on trial accused of stealing millions from various banks through multiple mortgages on the same properties.
Michael Lynn, with an address at Millbrook Court, Red Cross, Co Wicklow, denies twenty-one counts of theft between October 2006 and April 2007.
He has replied not guilty to each of the 21 charges he faces.
The prosecuting barrister, Patrick McGrath SC, then gave the jury an overview of the case he plans to present over the next 12-14 weeks.
He said the allegation against Mr Lynn is that he 'dishonestly and deceitfully' obtained multiple mortgages over the same properties under the pretence that he was seeking individual finance for the purpose of each property.
He’s alleged to have stolen a total of €27m from seven financial institutions.
Mr McGrath told the jurors it will be alleged that he used forged documents being used to secure mortgage finance.
He said the first tranche of evidence relates to a house in Howth, Co Dublin.
In relation to this purchase alone, he said it will be alleged that Mr Lynn stole €11.7m from three of the lenders.
