The law of international responsibility is one of international law's core foundational topics. Written by international experts, this book provides an overview of the modern law of international responsibility, both as it applies to states and to international organizations, with a focus on the ILC's work.

This rich and remarkable volume offers an overview of the most important schools, movements and trends which make up the theoretical landscape of contemporary international law, as well as the works of over 500 authors. It moves beyond generalization and examines how the relevant literature deals with the basic issues of the international legal system, such as international obligations, legitimacy, compliance, unity and universality, the rule of law, human rights, use of force and economics. It offers insights into the addressees (the state, international organizations, individuals and other private persons), and the construction of international law, including law-making, the relationship between norms, and interpretation. Moreover, it widens the discourse by addressing old, yet enduring, as well as new concerns about the functioning of the international legal system, and presents views of non-international lawyers and political scientists regarding that system. It is a valuable analysis for researchers, students, and practitioners.

This book examines some of the most prominent contemporary theories of compliance with international law. It is argued that these theories ultimately rely on some political philosophy and that therefore their strengths and weaknesses can be traced back to those of the respective philosophical background. The approach finally taken is based on some recent empirical and theoretical research undertaken and as such provides new insights to the major works of the authors that are at the core of the discussion.

Two fish are swimming in a pond. 'Do you know what?' the fish asks his friend. 'No, tell me.' 'I was talking to a frog the other day. And he told me that we are surrounded by water!' His friend looks at him with great scepticism: 'Water? Whats that? Show me some water!' International lawyers often find themselves focused on the practice of the law rather than the underlying theories. This book is an attempt to stir up 'the water' that international lawyers swim in. It analyses a range of theoretical approaches to international law and invites readers to engage with different ways of legal thinking in order to familiarize themselves with the water all around us, of which we hardly have any perception. The main aim of this book is to provide interested scholars, practitioners, and students of international law and other disciplines with an introduction to various international legal theories, their genealogies, and possible critiques. By providing an analytical approach to international legal theory, the book encourages readers to enhance their sensitivity to these different approaches and to consider how the presuppositions behind each theory affect analysis, research, and practice in international law. International Law Theories is intended to assist students, scholars, and practitioners in reflecting more generally about how knowledge is formed in the field.

The first suggests that states can be held responsible because they are 'moral agents' like human beings, with similar capacities for deliberation and intentional action. A state is responsible in the same way in which an indivdiual is responsible. The second sthat states can be held responsible because they are legal persons that act vicariously through their officials; states are 'principals' rather than agents, and the model for state responsibility is a case of vicariously liability, such as when an employer is held financially liable for the actions of her employee. Sam Fleming reconstructs and develops a forgotten understanding of state responsibility from Thomas Hobbes' political thought. Like proponents of the two theories of state responsibility, Hobbes considered states to be 'persons', meaning that actions, rights, and responsibilities can be attributed to them. States can be said to wage war, possess sovereignty, and owe money.

A dialogue between international responsibility lawyers and legal philosophers laying the groundwork for new research and legal reform.

State responsibility in international law is considered one of the cornerstones of the field. For a long time it remained the exclusive responsibility system due to the primacy of States as subjects of international law. Its unique position has nonetheless been challenged by several developments both within and outside the international legal order, such as the rise of alternative responsibility ideas and practices, as well as globalization and its consequences. This book adopts a critical and holistic approach to the law of State responsibility and analyzes the functionality of the general rules of State responsibility in a changed international landscape characterized by the fragmentation of responsibility. It is argued that State responsibility is not equally relevant across the broad spectrum of international obligations, and that alternative constructions of responsibility, namely international criminal law and international liability, have increased in standing.
