An article from Out-Law poses this question, in the light of a Supreme Court case which will decide the issue of whether, and to what extent, a person who has not been charged with an offence can have a reasonable expectation of privacy in relation to information that relates to a criminal investigation into their activities. It is said that a critical question in this context is whether information relating to a criminal investigation prior to the point of charge is private, noting that identification of suspects prior to charge is not currently regulated by statute. The case involves an article from Bloomberg using information about a US citizen from a letter of request for mutual legal assistance that had been sent by one law enforcement body to another.
