Regina v N(A); Regina v Le [2012] EWCA Crim 189; [2012] WLR (D) 38
“The implementation of the United Kingdom’s obligation to comply with article 26 of the Council of Europe Convention on Action Against Trafficking in Human Beings 2005 would normally be achieved by the proper exercise of the long established prosecutorial discretion which enabled the Crown Prosecution Service, however strong the evidence might be, to decide that it would be inappropriate to proceed with the prosecution of a defendant suspected of being involved in unlawful activities if he/she might have been the victim of trafficking for labour exploitation and might be unable to advance duress as a defence but who fell within the protective ambit of article 26.”
