The Idea of International Human Rights Law delves into the academic discipline of international human rights law, presenting it as both distinct from and interconnected with general international law. Author Steven Wheatley explores how the concept of human rights shapes legal practices at an international level without relying on a single moral philosophy or political theory. Instead, he examines the term’s meaning through its practical applications in various legal contexts such as the United Nations, core human rights treaties, and customary international law. Utilizing complexity theory to analyze these legal practices, Wheatley illustrates how the moral concept of human rights evolves within the social world, highlighting its dynamic nature and influence on international legal frameworks. This approach not only elucidates the unique position of international human rights law but also sheds light on the fragmentation of general international law.
