"These are more than allegations – these are pieces of a puzzle that are being put together. It makes an immediate criminal investigation absolutely inescapable." On 12 March 2009, in an op-ed piece in The Guardian, the analyst Timothy Garton Ash called for Mohamed's claims of torture and MI5 collusion to be referred to the Director of Public Prosecutions. He said that any other decision "will inevitably be interpreted as a political cover-up." On 10 February 2010, the UK Court of Appeal ruled that material held by the UK Foreign Secretary must be revealed. "MI5 knew that Binyam Mohamed, the former Guantanamo detainee, was being tortured by the CIA, a Court of Appeal judgment has revealed." The court opinion noted: The former detainees' suit against the government for the collusion of MI5 and MI6 in the unlawful treatment by the CIA, was eventually tried in 2009. Despite attempts by the Foreign Secretary, David Miliband, to suppress evidence on the grounds that such disclosure would harm national security, the government lost the case in the High Court. 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. On 27 January 2010, The Guardian reported that "United Nations human rights investigators had concluded that the British government had been complicit in the mistreatment and possible torture of several of its own citizens during the 'war on terror'". Among listed cases in which the authors concluded that a state has been complicit in secret detention, they highlight "the United Kingdom in the cases of several individuals, including Binyam Mohamed". On 10 February, three Court of Appeal judges ordered the British government to reveal evidence of
