International Law in the U.S. Legal System decodes the often complicated ways that international law operates within the United States legal system and sheds light on unresolved issues and areas of controversy. The book covers all of the principal forms of international law including treaties, decisions and orders of international institutions, customary international law, jus cogens norms, and general principles. It also explores a number of issues that are implicated by the intersection of U.S. law and international law, such as foreign sovereign immunity, international human rights litigation, extradition, and extraterritoriality.
