An Introduction to Public International Law

This chapter begins by introducing a number of foundational concepts, which serve as the starting point in the field of public international law. Section 1 of this chapter begins with the notion that states are sovereign equals, which must consent to be bound by nternational law. This section also introduces the critical distinction that international law makes between states and “non-state actors.” Section 2 of this chapter discusses the inevitable comparison of public international law with domestic legal systems, and the significant limitations of this analogy as a means for understanding the field of public international law. Section 3 concludes by explaining this book’s overarching structure, as well as the approach of this book to the introduction of public international law.
