The core of a terrorism trial must be held in secret so that justice can be done, the Court of Appeal has ruled.
Three judges found the course was justified in the "exceptional" case of Erol Incedal and Mounir Rarmoul-Bouhadjar, who are facing charges at the Old Bailey.
Lord Justice Gross said: "The rule of law is a priceless asset of our country and a foundation of our constitution. One aspect of the rule of law – both a hallmark and a safeguard – is open justice, which includes criminal trials being held in public and the publication of the names of defendants.
"Open justice is both a fundamental principle of the common law and a means of ensuring public confidence in our legal system; exceptions are rare and must be justified on the facts."
