Irish Bank Resolution Corporation has secured judgment for €16.2m against jailed businessman Breifne O'Brien.
High Court President Nicholas Kearns said the State-owned bank, formed following the merger of Anglo Irish Bank and Irish Nationwide Building Society, was entitled to summary judgment of the amount it sought against O'Brien.
He is currently serving a seven-year prison sentence for running a ponzi scheme that cost his victims millions of euro.
The bank's application was opposed by O'Brien, who represented himself in the proceedings.
The former businessman, who was accompanied to court by prison officer, argued he has an arguable defence against judgment being made against him and said IBRC's application should go to a full hearing.
IBRC, represented by Joe Jeffers BL, sought summary judgment against both O'Brien, and his father Leo arising out of a failure to repay loans advanced by INBS in 2002, 2004 and 2006.
Counsel said the money was used to purchase investment properties in locations including Cork and Monkstown in Co Dublin.
Following a default on repayments, a demand was made by IBRC for the amounts due on the loans.
The demand had not been satisfied, counsel said.
O'Brien, of Kilmore, Monkstown Grove, south Dublin, but currently in Mountjoy Prison, argued that he did not have enough time to prepare for the bank’s application.
He said he only discovered a few days ago that the application for summary judgment was due before the court.
Another defence he submitted was that a freezing order made against him by the High Court in 2009 had affected his ability to service the loans.
Other grounds he advanced as to why summary judgment should not be granted included claims the loans in question were provided as a result of reckless lending and undue influence by INBS.
However, Mr Justice Kearns said he was satisfied O'Brien had not made out an arguable defence to the claim. He dismissed all grounds he advanced, stating that several of them were merely "bald assertions".
He did not accept the lack of access to files and documents was a valid argument and added that the proceedings for summary judgment had been in train for some time.
The judge rejected claims that the freezing orders in 2009 could be advanced as a arguable defence.
The purpose of the freezing orders in 2009 preventing him from reducing his assets below a value of €14.5m was designed to prevent assets from being removed from this jurisdiction.
The freezing order did not prevent him from fulfilling his normal obligations, including making repayments on the loans.
IBRC's application for judgment in a similar amount against Leo O'Brien was adjourned to a date next month.
Last October O'Brien was jailed after he pleaded guilty to 14 sample counts of deception and theft involving around €8.5m between 2003 and 2008.
Dublin Circuit Criminal Court heard O'Brien dishonestly induced five people to advance millions of euro to him to invest in bogus property deals in Manchester, Paris and Hamburg.
O'Brien also got them to invest money in a bogus insurance scheme.
