The former Anglo Irish Bank has described the evidence of the Quinns, denying that they had breached court orders in relation to international assets, as "incredible and fantastic".
The Irish Bank Resolution Corporation claims the three men are in contempt of court because they continued to take steps to put certain assets in Russia and the Ukraine out of the reach of the bank.
This was despite High Court orders preventing them from doing so.
The bank's Senior Counsel, Shane Murphy, told Ms Justice Elizabeth Dunne that on an assessment of the evidence, she would be satisfied beyond reasonable doubt that the Quinns breached the court orders made in June and July last year.
Mr Murphy said the evidence showed there was a plan authorised by Seán Quinn Senior to put assets out of the reach of the bank, that it was developed by his nephew, Peter Quinn and that Seán Quinn junior was also aware of the plan.
The bank said the judge was being asked to accept that no-one was in overall charge of this plan. The bank claims Seán Quinn senior was in charge. He was the "patriarch", the "master and commander", Mr Murphy said.
He said the judge should take into account his anger and animus towards the bank.
Mr Murphy said there was false, misleading and evasive testimony from all three men.
Mr Murphy said the plan to put assets out of reach of the bank was executed with determination and resilience and with assistance in many jurisdictions. He said it continued beyond the dates of the injunctions.
The Quinns claim any steps they took in relation to putting the assets beyond the reach of the bank were taken before the injunctions were granted. They say they do not know anything about steps taken afterwards.
The legal submissions in the case being taken by the IBRC against the Quinns will continue tomorrow. Seán Quinn, his son Seán Junior and nephew, Peter have all been excused from attending as Seán Junior is getting married.
