Judgement has been reserved in a convicted double murderer's High Court challenge to being returned to prison.
With Martin Corey's liberty currently at stake, Mr Justice Treacy is expected to deliver his verdict as soon as possible.
The case centres on the alleged secrecy surrounding the basis upon which the 61-year-old’s licence was revoked.
Corey, from Lurgan in Co Armagh, received a life sentence in 1973 for the murders of two RUC men. He was released on licence in 1992, having served 19 years behind bars.
But in April 2010, the then Secretary of State Shaun Woodward ordered his recall on the basis of what has been described as “closed material”.
Corey issued judicial review proceedings against the Independent Parole Commissioners.
His barrister, Karen Quinlivan QC, argued that claims of involvement with dissidents have been made, without going into detail.
The court heard that it had been impossible to challenge the revocation order because of the undisclosed information.
According to Ms Quinlivan the Grand Chamber of the European Court of Human Rights and the House of Lords have both made it clear that details must be given in such circumstances.
