The High Court has reserved judgment in trespass proceedings against solicitor Brian O'Donnell.
Earlier, representatives for the Bank of Ireland told the Court that Mr O'Donnell had no "legal basis" for his "Walter Mitty" assertions that he had a right to reside at the Gorse Hill mansion in Killiney, South Dublin.
Mr Justice Brian McGovern told the High Court that after several hours of proceedings - he will reserve judgment until an unspecified time and date.
Today, solicitor Brian O'Donnell told the Court he did not know how much he owed Bank of Ireland - the bank seeking the trespass order against him.

He believes he had a right to residence at Gorse Hill in Killiney since 2000 – and claims that the bank was aware of this.
Representatives for the Bank of Ireland have said there is no 'legal basis' for Mr O'Donnell's claim to be allowed to stay at the mansion.
