This volume resulted from the International Conference on the Administration of Justice and National Security in Democracies, held in Ottawa in June 2007 and organized jointly by the Courts Administration Service and the Canadian Centre of Intelligence and Security Studies at Carleton University. The Conference brought together members of the judiciary, government officials, and academics from democracies around the world to share their views on the continuing importance and ongoing challenges of the administration of justice and the rule of law in the context of modern threats to national security, in particular those posed by transnational Islamist terrorism.
