(4) A person detained under this paragraph shall …..be released not later than the end of the period of nine hours beginning when his examination begins” THE FACTS 6. The following account of the facts is derived to a considerable extent from the judgment of Laws LJ. Mr Miranda is a Brazilian citizen and the spouse of Mr Glenn Greenwald, a journalist who at the material time was working for the Guardian newspaper. Some months after an initial contact made in late 2012 Mr Greenwald and another journalist, Laura Poitras, met Mr Edward Snowden. He provided them with encrypted data which had been stolen from the National Security Agency (NSA) of the United States. The data included UK intelligence material. Some of it formed the basis of articles in the Guardian on 6 and 7 June 2013 and on later dates. On 12 August 2013, Mr Miranda travelled from Rio de Janeiro to Berlin in order to meet Laura Poitras. He was carrying encrypted material derived from the data obtained by Mr Snowden. He was to collect computer drives containing further such material. He was doing it in order to assist in the journalistic activity of Mr Greenwald. He was stopped at 08.05 on Sunday 18 August 2013 at Heathrow where he was in transit on his way back to Rio de Janeiro. 7. The Security Service (for which the first defendant Secretary of State is responsible by statute) had undertaken an operation relating to Mr Snowden. They became aware of Mr Miranda’s movements. At 08.30 on Thursday 15 August 2013 they briefed Detective Superintendent Stokley of SO 15, the Counter-Terrorism Command in the Metropolitan Police (“MPS”), the second defendant. 8. The Security Service told him that one of the individuals involved in disseminating the stolen intelligence material was Mr Greenwald, a freelance journalist for the Guardian, that Mr Miranda was married to him and was travelling from Berlin to Rio and may have some sensitive material in his possession. As Det Supt Stokley put it at para 10 of his first witness statement dated 23 September 2013, the Security Service wanted to explore “the various options around seizure and analysis of this material and what police colleagues could do to assist with that process.”
