The High Court has referred the case of Sean Garland to the Director of Public Prosecutions.
It comes after the court refused to extradite him to the US.
The former President of the Workers Party was wanted by the US authorities over his alleged role in counterfeiting dollars in collusion with the government of North Korea.
However in a lengthy written judgment issued today the court explained that the 76-year-old should not be surrendered abroad for an offence alleged to have been committed in Ireland.
Mr. Justice John Edwards says the Irish courts are entitled to assert jurisdiction in respect of a conspiracy formed in Ireland.
