This textbook introduction to international law and justice is specially written for students studying law in other departments, such as politics and IR. By showing how international politics is intimately connected to international law, Edwin Egede and Peter Sutch - a lawyer and a political theorist - show that justice and ethics are essential to understanding international society. To help students learn, key concepts are explained in text boxes and each chapter includes case studies, chapter summaries, revision questions and suggestions for further reading. Students will engage with the most crucial questions and critical debates: sovereignty and global governance, sovereign and diplomatic immunity, human rights, the use of force, sanctions and the domestic impact of international law.
