A 28-year-old Irishman, described by the FBI as the "largest facilitator of child porn on the planet", will find out tomorrow if he can make a new application for bail.
Eric Eoin Marques, who faces four charges relating to advertising and distributing online child pornography, was refused bail by the High Court last month.
Evidence was given that he was a flight risk and there was a risk that evidence could be destroyed.
His lawyers told the court this morning that the previous application was made when he was being held under a provisional extradition warrant, which allowed him to be held for 18 days.
They argued he should be allowed to make a new bail application now that he is facing full extradition proceedings.
However, lawyers for the State said nothing had changed since the original bail application had been made and refused.
They told the court a new bail application would be a waste of the court's time and would achieve no purpose.
Mr Justice John Edwards will rule in the morning on whether or not a new bail application can be made.
