A High Court judge has lashed out at the Quinn family's "deviousness" in attempting to put assets beyond the reach of the former Anglo Irish Bank.
Mr Justice Peter Kelly said their actions "reeked of dishonesty".
The judge's comments were made as he appointed receivers over assets owned by various members of the Quinn family.
Mr Justice Peter Kelly expressed his outrage at members of the Quinn family as he extended orders freezing the assets of the Quinn children and two in-laws.
He said he had been presiding over the commercial list since 2004 and has had to deal "more and more often with cases involving fraud, sharp practice, dishonesty and chicanery".
However he added that never had he seen such conduct on the scale demonstrated in the Quinns' case, nor with the "deviousness" with which this scheme had been operated.
The judge's comments refer to plans by bankrupt businessman Sean Quinn, his jailed son Sean Quinn Jnr and the missing Peter Darragh Quinn to put assets beyond the reach of IBRC.
On Tuesday, Mr Justice Peter Kelly will consider whether the Quinn children should continue to receive living expenses of €2,000 each per week.
