This manual outlines the fundamental human rights principles that are most commonly engaged in the fight against terrorism. It explains states’ obligations in respect of those rights when dealing with terrorism. Counter-terrorism strategies that are compliant with human rights not only avoid certain legal pitfalls, but may also prove more effective in the long term at winning the ideological battle against terrorism than strategies that themselves violate human rights., This manual is designed as both a stand-alone tool and as a complement to the OSCE/ODIHR training programme for policy makers and practitioners working in counter-terrorism in OSCE participating States. It explains how human rights standards and counter-terrorism techniques work hand in hand. The manual and training programme are aimed at assisting states in ensuring that their counter-terrorism strategies comply with human rights standards and, as such, are more likely to meet their objectives., Part I begins by emphasizing the relationship between human rights and counter-terrorism and stresses the need for clearly defined laws and principles to ensure the effectiveness of both. It then sets out the existing counter-terrorism and human rights frameworks in international law and discusses the ways in which the two ought to work together. Parts II and III outline key themes in promoting human rights and protecting against terrorism, and explain how human rights standards work, in particular the central principles most directly relevant to developing practical counter-terrorism strategies.
