"In a regional, national and global response to terrorism, the emphasis necessarily lies on preventing the next terrorist act. Yet, with prevention comes prediction: the need to identify and detain those considered likely to engage in a terrorist act in the future. The detention of "suspected terrorists" is intended, therefore, to thwart a potential terrorist act recognising that retrospective action is of no consequence given the severity of terrorist crime. Although preventative steps against those reasonably suspected to have an intention to commit a terrorist act is sound counter-terrorism policy, a law allowing arbitrary arrest and detention is not. A State must carefully enact anti-terrorism laws to ensure that preventative detention does not wrongly accuse and grossly slander an innocent person, nor allow a terrorist to evade detection. This book examines whether the preventative detention of suspected terrorists in State counter-terrorism policy is consistent with the prohibitions on arbitrary arrest and detention in international human rights law. This examination is based on the "principle of proportionality"; a principle underlying the prohibition on arbitrary arrest as universally protected in the Universal Declaration of Human Rights, and given effect to internationally in the International Covenant on Civil and Political Rights, and regionally in regional instruments including the European Convention on Human Rights.

The book is written from a global counter-terrorism perspective, drawing particularly on examples of preventative detention from the UK, US and Australia, as well as jurisprudence from the ECHR"--
