This book examines the application of UK Criminal and Human Rights Law to people and circumstances outside the United Kingdom. Building upon previous analyses which have focused on a single aspect of extraterritorially, this book examines the fields of Criminal and Human Rights law as the two main areas of non-private law which are frequently applied across borders. Both fields are placed in context before being drawn together in a coherent and systematic way. The book examines recent law and practice, as well as historic developments and explores the concept of enforcement. The author's analysis includes coverage of topics such as the criminalisation of sex-tourism, the extradition of white-collar criminals and the application of human rights law to Iraq following American and British intervention in the region. Law Across Borders goes on to point the way forward in the development of the extraterritorial application of public law, and suggests ways in which greater coherence can be achieved. This book will be of particular interest to practitioners, academics and scholars of International Law, Human Rights Law and Criminal Law. It is unique in its ambition to offer a comprehensive description and analysis of the extra-territorial application of UK Human Rights Law and Criminal Law in a single text.
