Eric Eoin Marques, who is alleged to be the owner and administrator of an anonymous hosting site known as Freedom Hosting, is wanted by US authorities to face charges relating to conspiring to distribute and advertise child pornography, and advertising and distributing child pornography.
The 28-year-old, with an address at Mountjoy Square in Dublin, has been in custody since his arrest in August last year, after he was refused bail over concerns he represented a flight risk and may abscond or interfere with evidence.
Last December, the extradition court heard the DPP had decided not to bring proceedings against Mr Marques with respect to the alleged offences. The court heard a detailed letter had been submitted to the DPP, in which it was indicated Mr Marques would enter a plea of guilty were the offences to be prosecuted in this jurisdiction.
Last month at the High Court, Mr Justice John Edwards said he had decided to refuse Mr Marques leave to challenge, by way of judicial review, the decision not to prosecute him.
Mr Justice Edwards said that Mr Marques would also not be granted leave to seek judicial review of the refusal of the DPP to give reasons for not prosecuting him.
Yesterday, the High Court heard his legal team will be going to the Supreme Court over the judicial review decision.
The High Court will hear an application to put a stay of the extradition proceedings on October 23.
Mr Marques was remanded in custody until then.
