Billionaire-turned-bankrupt Sean Quinn - who counted The Belfry golf complex among his many properties - has all been found in contempt of court for putting assets beyond the reach of the former Anglo-Irish Bank.
The former business tycoon, once Ireland's richest man, his son Sean and nephew Peter Darragh, were found to have defied an order at the High Court in Dublin over the family's international property portfolio.
The lawsuit, brought by the State-owned bank which was rebranded last year to become the Irish Bank Resolution Corporation, claimed they shifted assets from as far afield as Ukraine and Russia into new ownership as it pursued £2.23 billion in debts.
The contempt ruling was delivered by Mrs Justice Elizabeth Dunne at the Four Courts in Dublin.
It is the latest court battle the Fermanagh-born businessman has lost after he secured bankruptcy in Northern Ireland only for it to be overturned and a Dublin court then to declare him bankrupt.
The contempt lawsuit is one of a series of cases across several jurisdictions as the zombie bank tries to recover a 500 million euro (£402 million) international property portfolio to cover unprecedented debts run up by Mr Quinn in secret and ill-fated share deals in Anglo.
Potential punishment for contempt of court in Ireland ranges from fines and seizure of property to a jail sentence.
In a hard-hitting judgment criticising the Quinns, Mrs Justice Dunne ruled that Sean Quinn's evidence was not credible.
She said it was "impossible to accept the evidence of Sean Quinn Senior that he had no hand, act or part in Quinn business after April 2011".
A receiver had been appointed by that time to the Quinn Group after Sean Quinn ran up the huge debts on a stock market gamble that the Anglo share price would keep rising.
The judge went on to say that his son Sean was not telling the truth and that the evidence of nephew Peter Darragh Quinn was "most untruthful".
The Quinns are expected back in the High Court on Friday, when arguments will be put forward for further action to be taken against them over the contempt.
The Birmingham Post has reported that talks are taking place to sell The Belfry.
