Businessman Seán Quinn was in court in Belfast this afternoon where the Irish Bank Resolution Corporation - the former Anglo Irish Bank - is seeking to have his bankruptcy overturned.
Mr Quinn has been declared bankrupt in Northern Ireland but IBRC claims he is not entitled to file for bankruptcy there as the majority of his business is conducted in the Republic.
Mr Quinn arrived at Belfast's Royal Courts of Justice building this morning accompanied by his son-in-law Niall McPartland.
The Fermanagh-born entrepreneur had been directed by Judge Donal Deeny to make himself available for this hearing following his initial bankruptcy petition in November.
The judge acknowledged Mr Quinn's presence and his legal team said he had a strong desire to give evidence, but it is not yet clear whether the businessman will be required to do so.
IBRC began outlining its case to have the bankruptcy annulled this afternoon.
Gabriel Moss QC on behalf of IBRC said Mr Quinn had not fulfilled his duty to disclose all relevant information to the court at his initial application hearing last month.
He said IBRC would argue that the Republic of Ireland and not Northern Ireland was Mr Quinn's centre of main business interest.
Should he succeed in declaring bankruptcy in the North over Anglo's objections, Mr Quinn could be back in business within a year.
Bankruptcy in the Republic, however, would take up to 12 years to discharge.
