The High Court has rejected all the arguments supporting David Miranda’s application for judicial review of his detention at Heathrow Airport in August last year. In a highly readable and pungent judgment, Laws LJ has some robust things to say about the vaunting of journalistic interests over public security in the guise of Article 10, and the ‘mission creep’ of requirements demanded by the courts for state action to be considered “proportionate”.

This is the long-awaited conclusion to the substantive hearing since judicial review proceedings were initiated seven months ago (for more, see The detention of David Miranda – a disturbing use of state power?). It will be remembered that Miranda was detained and questioned by police officers under the Terrorism Act 2000, and various items in his possession, notably encrypted storage devices, were taken from him. Miranda claims that all this was done without any legal authority.
