An American military lawyer and veteran of dozens of secret Guantanamo tribunals has made a devastating attack on the legal process for determining whether Guantanamo prisoners are "enemy combatants".
The whistleblower, an army major inside the military court system which the United States has established at Guantanamo Bay, has described the detention of one prisoner, a hospital administrator from Sudan, as "unconscionable".
His critique will be the centrepiece of a hearing on 5 December before the US Supreme Court when another attempt is made to shut the prison down. So nervous is the Bush administration of the latest attack – and another Supreme Court ruling against it – that it is preparing a whole new system of military courts to deal with those still imprisoned.
