Although over 70 countries have developed data privacy laws, there is a lack of expert guidance on these laws. This text is the first to examine the fundamental aims and principles of data privacy law, along with the mechanisms for its enforcement in an international context. Bygrave analyses relevant law from around the globe, paying particular attention to international instruments and using these as a foundation for examining national law. Through a consideration of data privacy law within a broader legal and political framework, this book focuses upon itsinterrelation with human rights, administrative law, employment law, consumer protection law, intellectual property rights, and competition law. Bygrave also examines the regulatory challenges that face data privacy law, and explores its future utility and efficacy.
