Reporting restrictions sometimes cover specific parts of cases The Court of Appeal is to rule on whether a trial of two terrorist suspects can be heard in secret. The Crown Prosecution Service (CPS) says a secret trial is in the interests of national security.
It would become the first jury trial to be heard entirely behind closed doors in England.
Details of the case emerged at an appeal against an order issued in May, which banned the identification of the defendants and access to the trial.
Media challengeThe media were banned from reporting the existence of that order until the Court of Appeal hearing, and its judges are now ruling on the media's challenge to the case restrictions.
Reporting restrictions sometimes cover specific parts of cases, but this case - which relates to two defendants referred to as "AB" and "CD" - would be the first to feature a jury in a normal courtroom hearing evidence in secret.
The court heard that AB and CD had been arrested "in high-profile circumstances" and faced allegations of the preparation of terrorist acts and possessing bomb-making instructions.
The court was also told that if a decision was made to hold the trial in open court, and identify the defendants, the CPS could abandon the prosecution.
