Computer expert Babar Ahmad has been held in a UK prison without trial for eight years after being accused of raising funds for terrorism.
His judicial review application will be heard today along with that of radical cleric Abu Hamza and another suspect, Khaled Al-Fawwaz.
The Director of Public Prosecutions Keir Starmer QC has refused to consent to the private prosecution of terror suspects Babar Ahmad and Syed Ahsan.
Babar Ahmad's family has urged Home Secretary Theresa May to halt his extradition until a decision is made on a potential private prosecution in the UK. In a statement released following the move, the family said:
"We are simply asking for the court to put a hold on Babar's extradition so that the DPP has the necessary time and space to make a decision on the material provided to him in April 2012 which was kept hidden from him by the police for eight years.
"The DPP has confirmed that he is considering this material in addition to the request by Mr Karl Watkin for permission to privately prosecute Babar in the UK.
"We trust that the court will find that this is a reasonable request which is both in the public interest and the interests of justice."
Terror suspect Babar Ahmad has launched a High Court bid to halt his removal from the UK to the United States, it was confirmed earlier.
