‘This book makes an interesting and original contribution to the field of human rights law by exploring the distinctive question of the extent to which states are (and should be) bound by human rights when they cooperate transnationally with other states - for example in areas such as anti-terrorism, intelligence-sharing or extradition. It combines careful scholarly analysis of existing rules of international law with proposals for further developing an “international human rights law of cooperation” to strengthen the responsibility of states for protecting human rights when they cooperate with other states.’
