Bankrupt businessman Sean Quinn has so far avoided jail, but that could change after contempt proceedings return to the High Court today.
His son Sean Quinn Jnr is also at risk of a fresh spell in Mountjoy having already served a three month sentence for breaching a court order.
Sean Quinn has had 13 days to get his house in order since his last court appearance when his lawyers maintained that he wants to co-operate with IBRC and purge his contempt.
They described him as a 66-year-old man who has had two serious heart operations dealing with a risk to his liberty.
However IBRC claimed the bankrupt businessman had done nothing to comply with orders aimed at reversing a scheme to strip valuable property assets fron Quinn companies.
The bank said it was gravely concerned by new evidence showing the Quinns are still in control of these companies.
If Ms Justice Elizabeth Dunne finds against Sean Quinn and his son Sean Quinn Jnr, both men could face prison.
