The High Court will decide next week if it is to grant further orders restraining Sean Quinn and members of his family from making changes to their international businesses.
Anglo Irish Bank was back in court today seeking further injunctions preventing changes to the structure of, or the transfer of assets from, Quinn companies abroad.
In a previous hearing the bank, which is owed an estimated €2.8 billion by Quinn interests, alleged a "conspiracy" and a "pattern of dispossession" in the Quinn family to strip companies of their assets and reduce the bank's security.
The bank claimed it was operating in an "information deficit" in respect of the Quinns' conduct in various jurisdictions.
The court was told new information "comes to light on an almost daily basis" about overseas companies owned by the Quinn family.
It alleged "a sinister pattern in Sweden, Russia, Ukraine, India and Cyprus" of conspiracy by the Quinns to put valuable assets beyond the reach of Anglo.
The applications today follow the granting of similar injunctions last month by Mr Justice Frank Clarke.
Anglo claims that the court also has discretion under EU law to grant similar injunctions and is seeking court protection under those laws.
Senior counsel Brian Murray said the bank was entitled to seek the protection from the Irish courts because nine of the defendants were resident here and the original loan agreements were subject to Irish law.
This was the logical jurisdiction, he said.
Last month injunctions were granted pending a decision due next week on whether or not the Irish courts have jurisdiction to rule on the dispute.
The Quinn family's international properties are worth an estimated €500m.
Court proceedings have been taken in Sweden, Cyprus and Russia over control of the foreign properties.
Senior counsel for the Quinns, Bill Shipsey questioned if an Irish court was the best place to decide on companies which were not registered in Ireland and did not have assets in Ireland.
There was nothing to prevent Anglo taking the proceedings abroad, where the companies are located.
He said no explanation had been given as to why this had not happened.
The bank was not entitled to "forum shop" to see where it would get better protection, he said.
The fact that many of the respondents were resident here was not enough, he said.
There was an evidential deficit in Anglo's application requesting the court to exercise its exceptional discretion under EU law to grant protection, he said.
Mr Justice Frank Clarke will rule on all issues next week.
