Internet jurisdiction has emerged as one of the greatest and most urgent challenges online, severely affecting areas as diverse as e-commerce, data privacy, law enforcement, content take-downs, cloud computing, e-health, Cyber security, intellectual property, freedom of speech, and Cyberwar. In this innovative book, Professor Svantesson presents a vision for a new approach to Internet jurisdiction––for both private international law and public international law––based on sixteen years of research dedicated specifically to the topic. The book demonstrates that our current paradigm remains attached to a territorial thinking that is out of sync with our modern world, especially, but not only, online. Having made the claim that our adherence to the territoriality principle is based more on habit than on any clear and universally accepted legal principles, Professor Svantesson advances a new jurisprudential framework for how we approach jurisdiction. He also proposes several other reform initiatives such as the concept of ‘investigative jurisdiction’ and an approach to geo-blocking, aimed at equipping us to solve the Internet jurisdiction puzzle. In addition, the book provides a history of Internet jurisdiction, and challenges our traditional categorisation of different types of jurisdiction. It places Internet jurisdiction in a broader context and outlines methods for how properly to understand and work with rules of Internet jurisdiction. While Solving the Internet Puzzle paints a clear picture of the concerns involved and the problems that needs to be overcome, this book is distinctly aimed at finding practical solutions anchored in a solid theoretical framework.
