The Criminal Assets Bureau has confiscated more than €630,000 from prominent Republican Thomas 'Slab' Murphy.
The High Court gave CAB the orders to hand the money over to the Exchequer.
CAB has been investigating the activities of Mr Murphy for a number of years.
In March 2006 CAB, local gardaí, customs officers and detectives from the fraud bureau and the National Bureau of Criminal Investigation raided his home and business premises at Ballybinaby, Hackballscross, Co Louth.
It was also the address of Ace Oils Ltd and CAB officers subsequently told the High Court that Mr Murphy and his brothers Frank and Patrick had been involved in oil smuggling and money laundering for 20 years.
They also removed cash and cheques in black plastic bags. Today, the High Court granted them an order confiscating over €635,000.
Mr Justice Frank Clarke said he was satisfied the money was the proceeds of crime and the total, made up of €435,000 and £150,000, will be handed over to the Exchequer.
Mr Murphy is still before the courts on charges facing tax offence charges.
His brothers, Patrick and Frank, have reached tax settlements with CAB for a figure understood to be over €1m.
