Elgizouli v Secretary of State for the Home Department [2020] UKSC 10

El Shafee Elsheikh was involved with ISIS and is alleged to have been involved in the beheadings of 27 citizens from the UK and the US. The UK provided legal assistance to the Americans but broke with convention by not requiring assurances that the evidence would not be used as part of a prosecution that could lead to the imposition of the death penalty. In this judicial review claim that decision by the Home Secretary was challenged on not only human rights grounds but also on the basis of data protection legislation as well. Music from bensound.com
