On 14 December, Miliband appealed against six High Court rulings that CIA information on Mohamed's treatment, and what MI5 and MI6 knew about it, must be disclosed. In an unprecedented case, counsel for "The Guardian" and other media organisations, Mohamed and two civil rights groups, Liberty and Justice, argued that the public interest in disclosing the role played by British and US agencies in unlawful activities far outweighed any claim about potential threats to national security. On 20 December, a U.S. District Court judge, Gladys Kessler, found that there was "credible" evidence that a British resident was tortured while being detained on behalf of the US Government. Her formerly classified legal opinion, obtained by "The Observer," records that the US Government does not dispute "credible" evidence that Binyam Mohamed had been tortured while being held at its behest.
