Business and Human Rights Law is a rapidly growing area of law, which has dramatically transformed many parts of international law. In this new volume in the Elements series, Robert McCorquodale explores how the responsibility for human rights abuses has transitioned from a purely state obligation to also being the responsibility of businesses. Business responsibility for human rights impacts have become subject both to legislation and to court decisions whenever their activities lead to human rights abuses anywhere in the world. This book shows the importance of the UN Guiding Principles on Business and Human Rights in these developments, and examines their influence on international, regional, and national law. It also analyses the changes on state obligations to protect human rights, on the corporate responsibility for human rights abuses, and on effective access to remedies for those adversely affected by business activities. Each of these shifts has consequences on core tenets of international law, such as sovereignty and jurisdiction, and has implications for crafting new international law in areas such as climate change and technology. Robert McCorquodale brings his decades of experience in scholarship and legal practice in business and human rights law, as well as his extensive engagement with businesses, governments, civil society, and international organisations, to bear on his understanding and analysis of this increasingly important field.
