The Supreme Court has ruled that a man being sought by the US on terrorism charges can challenge the Director of Public Prosecution's decision not to prosecute him in Ireland.
The court overturned the High Court's decision and ruled that Ali Charaf Damache is entitled to take judicial review proceedings challenging the refusal to prosecute him and the DPP's refusal to give reasons for the refusal.
The Chief Justice, Ms Justice Susan Denham, said the court wanted all matters concerning Mr Damache to proceed to hearing as soon as possible in the High Court.
Mr Damache, who is 50, is an Algeria-born Irish citizen who had an address in Waterford.
He is wanted by US authorities in connection with an alleged conspiracy to provide support to terrorists.
The US also alleges he conspired with American woman,Colleen La Rose, who used the online name, "Jihad Jane", and others to create a terror cell in Europe.
If convicted in the US, he could face up to 45 years in prison.
