The events of 11 September 2001 triggered wide ranging national and international legislative changes to counter the increased threat to terrorism. The UKs legal responses to terrorism are widely regarded as a model of effective anti-terrorism measures. This is the first book to combine, in one volume, the UKs cases and materials on combating terrorism. It includes all the relevant executive and legislative acts, international treaties, conventions and case law. It will be an essential reference tool for lawyers who specialise in international law, criminal law and human rights law, as well as law enforcement agencies, policy makers and academic communities.
