Detention in the context of counterterrorism and armed conflict: Continuities and new challenges

Abstract This article explores recent practices of States in relation to counterterrorism and armed conflict detention. Recent cases in the courts of the UK and US are drawn on to demonstrate the continued defence by those States of their administrative detention practices. Furthermore, the practice of other States in adopting new administrative detention laws as part of their counterterrorism strategies is explored. Finally, two examples of contemporary controversies are then considered to show where much of the debate is likely to be focused in the coming years, namely the use of other administrative measures short of detention, particularly assigned residence, and detentions carried out by armed groups that are supported by foreign States.
