Appeal Judges upheld a decision made in November by the Special Immigration Appeals Commission (SIAC):
SIAC was entitled to conclude that there is a real risk that the impugned statements will be admitted in evidence at a retrial and that, in consequence, there is a real risk of a flagrant denial of justice.

The Home Secretary pinned her hopes for ousting Abu Qatada from Britain on a fresh deal with the Jordanians.
A Tory MP and former government lawyer give their view on the UK potentially withdrawing from the ECHR to aid Abu Qatada's deportation.
The Government has been refused permission to take its fight to remove preacher Abu Qatada from the UK to the Supreme Court.
